In one example, the power receiving and substation equipment is used in a power distribution substation. In this case, the voltage of 66 kV is reduced to a voltage of 6 kV due to voltage conversion in the power receiving and transforming equipment. Then, the electricity whose voltage has been lowered to 6 kV is transmitted from the distribution substation through the distribution line.
図１は、電気所における受変電設備１の建設後の状態の一例を示し、図２は、電気所における受変電設備１の建設後の状態の図１とは別の一例を示す。図１の一例では、電気所の敷地内に２種類の受変電設備１Ａ，１Ｂが建設され、図２の一例では、電気所の敷地内に１種類の受変電設備１Ａが建設される。受変電設備１Ａ，１Ｂを含む受変電設備１では、鉛直方向に相当する高さ方向（矢印Ｚで示す方向）、鉛直方向に対して交差する（直交又は略直交する）第１の水平方向に相当する横方向（矢印Ｙで示す方向）、及び、鉛直方向及び第１の水平方向の両方に対して交差する（直交又は略直交する）第２の水平方向に相当する奥行方向（矢印Ｘで示す方向）が、規定される。 FIG. 1 shows an example of a state of the power receiving and transforming equipment 1 at an electric station after construction, and FIG. 2 shows an example of the state of the power receiving and transforming equipment 1 at an electric station after construction, different from FIG. 1. In the example of FIG. 1, two types of power receiving and transforming equipment 1A and 1B are constructed within the premises of an electric station, and in the example of FIG. 2, one type of power receiving and transforming equipment 1A is constructed within the premises of an electric station. In the power receiving and transforming equipment 1 including the power receiving and transforming equipment 1A and 1B, in the height direction corresponding to the vertical direction (the direction indicated by arrow Z), and in the first horizontal direction that intersects (orthogonal or approximately orthogonal to) the vertical direction. The corresponding horizontal direction (direction indicated by arrow Y) and the depth direction (direction indicated by arrow direction) is defined.
受変電設備１は、架台２を備える。ある一例では、高さ方向に沿った架台２の寸法は、１５００ｍｍ程度となり、別のある一例では、高さ方向に沿った架台２の寸法は、２０００ｍｍ程度となる。受変電設備１では、架台２上に、建屋３が設置される。このため、建屋３は、高さ方向に沿った架台２の寸法だけ、地面から鉛直上側に離れて建設される。なお、建屋３でも、受変電設備１と同様に、高さ方向、横方向及び奥行方向が、規定される。 The power receiving and transforming equipment 1 includes a pedestal 2 . In one example, the dimension of the pedestal 2 along the height direction is about 1500 mm, and in another example, the dimension of the pedestal 2 along the height direction is about 2000 mm.

In the power receiving and transforming equipment 1B, the building 3 is assembled by joining the two container houses C1 and C2. Therefore, the container houses C1 and C2 are used in common for the power receiving and transforming equipment 1A and 1B, and the container house C3 is used only for the power receiving and transforming equipment 1A. Note that each wall of the container house C is formed of, for example, a panel that is nonflammable and has high heat insulation properties, and highly durable metal siding such as galvalume steel plate (registered trademark) .

図６は、受変電設備１において建屋３を形成する複数のコンテナハウスの１つであるコンテナハウスＣ１の内部構成を示す。図３、図４及び図６に示すように、受変電設備１のそれぞれでは、コンテナハウスＣ１の内部に、受変電機器ユニット５０が配置及び収納される。したがって、コンテナハウスＣ１は、受変電機器ユニット５０が収納される受変電機器用ハウスとなる。 FIG. 6 shows the internal configuration of a container house C1, which is one of a plurality of container houses forming the building 3 in the power receiving and transforming equipment 1. As shown in FIGS. 3, 4, and 6, in each of the power receiving and transforming equipment 1, a power receiving and transforming equipment unit 50 is arranged and housed inside the container house C1. Therefore, the container house C1 becomes a house for power receiving and transforming equipment in which the power receiving and transforming equipment unit 50 is housed.
図７は、受変電機器ユニット５０の構成の一例を示す。図６及び図７等に示すように、受変電設備１ＡにおいてコンテナハウスＣ１に収納される受変電機器ユニット５０Ａでは、前述した変圧器二次側部分２２、母線連絡部分１５Ａ、所内変圧部分１６及び複数の配電線部分１７が、１つのフレーム５１に一体に組付けられ、１つのフレーム５１の内部に一括して収納される。同様に、受変電設備１ＢにおいてコンテナハウスＣ１に収納される受変電機器ユニット５０Ｂでは、前述した変圧器二次側部分２２、母線接続部分１５Ｂ、所内変圧部分１６及び複数の配電線部分１７が、１つのフレーム５１に一体に組付けられ、１つのフレーム５１の内部に一括して収納される。 FIG. 7 shows an example of the configuration of the power receiving and transforming equipment unit 50. As shown in FIGS. 6, 7, etc., in the power receiving and transforming equipment unit 50A housed in the container house C1 in the power receiving and transforming equipment 1A, the above-mentioned transformer secondary section 22, bus bar connection section 15A, station transformer section 16, A plurality of power distribution line portions 17 are integrally assembled to one frame 51 and housed inside one frame 51 all at once. Similarly, in the power receiving and transforming equipment unit 50B housed in the container house C1 in the power receiving and transforming equipment 1B, the transformer secondary side portion 22, the busbar connection portion 15B, the in-house transformer portion 16, and the plurality of distribution line portions 17 are as follows: They are assembled into one frame 51 and housed all at once inside one frame 51.
受変電機器ユニット５０Ａでは、変圧器二次側部分２２、母線連絡部分１５Ａ、所内変圧部分１６及び複数の配電線部分１７のそれぞれが鉄の筐体に収納される構成である複数のキュービクルが設けられる構成とは異なり、変圧器二次側部分２２、母線連絡部分１５Ａ、所内変圧部分１６及び複数の配電線部分１７は、壁等によって互いに対して隔壁されず、互いに対して分離されていない。同様に、受変電機器ユニット５０Ｂでは、変圧器二次側部分２２、母線接続部分１５Ｂ、所内変圧部分１６及び複数の配電線部分１７は、壁等によって互いに対して隔壁されず、互いに対して分離されていない。 The power receiving and transforming equipment unit 50A includes a plurality of cubicles in which the transformer secondary side part 22, the busbar communication part 15A, the station transformer part 16, and the plurality of distribution line parts 17 are each housed in an iron casing. Unlike the structure shown in FIG. Similarly, in the power receiving and transforming equipment unit 50B, the transformer secondary side portion 22, the busbar connection portion 15B, the station transformer portion 16, and the plurality of distribution line portions 17 are not separated from each other by a wall or the like, but are separated from each other. It has not been.
前述のような構成であるため、受変電機器ユニット５０Ａでは、変流器２６，４１，４２、遮断器２７，４３、母線連絡遮断器３７及び所内変圧器３８等の装置群１０の一部を構成する複数の受変電機器が、互いに対して隔壁されることなく、フレーム５１に一体に組付けられる。同様に、受変電機器ユニット５０Ｂでも、装置群１０の一部を構成する複数の受変電機器が、互いに対して隔壁されることなく、フレーム５１に一体に組付けられる。したがって、受変電設備１のそれぞれでは、受変電機器用ハウスであるコンテナハウスＣ１の内部に、装置群１０の一部を構成する複数の受変電機器が互に対して隔壁されることなく一体に組付けられた受変電機器ユニット５０が、収納される。 Because of the configuration described above, the power receiving and transforming equipment unit 50A includes some of the equipment group 10, such as the current transformers 26, 41, 42, circuit breakers 27, 43, busbar connection circuit breaker 37, and station transformer 38. A plurality of constituent power receiving and transforming devices are integrally assembled to the frame 51 without being partitioned from each other. Similarly, in the power receiving and transforming equipment unit 50B, a plurality of power receiving and transforming equipments forming part of the device group 10 are integrally assembled to the frame 51 without being separated from each other. Therefore, in each of the power receiving and transforming equipment 1, a plurality of power receiving and transforming equipments constituting a part of the equipment group 10 are integrated together without being separated from each other inside the container house C1 which is a house for power receiving and transforming equipment. The assembled power receiving and transforming equipment unit 50 is stored.
受変電機器ユニット５０では、高さ方向、高さ方向に対して交差する（直交又は略直交する）前後方向、高さ方向及び前後方向の両方に対して交差する（直交又は略直交する）幅方向が、規定される。図６の一例では、受変電設備１のそれぞれにおいて、受変電機器ユニット５０は、前後方向が建屋３の奥行方向と一致又は略一致し、かつ、幅方向が建屋３の横方向と一致又は略一致する状態で、コンテナハウスＣ１に設置される。そして、受変電機器ユニット５０は、高さ方向が建屋３の高さ方向と一致又は略一致する状態で、コンテナハウスＣ１の内部に収納される。また、受変電機器ユニット５０のそれぞれでは、変圧器二次側部分２２、母線連絡部分１５Ａ（又は母線接続部分１５Ｂ）、所内変圧部分１６及び複数の配電線部分１７が、幅方向（建屋３の横方向）に並んで配置される。 In the power receiving and transforming equipment unit 50, the height direction, the front-back direction that intersects (perpendicularly or approximately orthogonally) to the height direction, and the width that intersects (orthogonally or approximately orthogonally) to both the height direction and the front-rear direction. A direction is defined. In the example of FIG. 6, in each of the power receiving and transforming equipment 1, the power receiving and transforming equipment unit 50 has a front-back direction that matches or substantially matches the depth direction of the building 3, and a width direction that matches or substantially matches the lateral direction of the building 3. They are installed in the container house C1 in a matching state. The power receiving and transforming equipment unit 50 is housed inside the container house C1 with its height direction matching or substantially matching the height direction of the building 3. Further, in each of the power receiving and transforming equipment units 50, the transformer secondary side portion 22, the busbar connecting portion 15A (or the busbar connecting portion 15B), the in-station transformer portion 16, and the plurality of distribution line portions 17 are arranged in the width direction (of the building 3). (horizontal direction).
また、受変電機器ユニット５０のそれぞれでは、１組の母線３６Ａ（又は３６Ｂ）によって、変圧器二次側部分２２、母線連絡部分１５Ａ（又は母線接続部分１５Ｂ）、所内変圧部分１６及び複数の配電線部分１７が、電気的に接続される。そして、受変電機器ユニット５０のそれぞれでは、変圧器二次側部分２２、母線連絡部分１５Ａ（又は母線接続部分１５Ｂ）、所内変圧部分１６及び複数の配電線部分１７が互に対して隔壁されていないため、母線３６Ａ（又は３６Ｂ）は、フレーム５１の内部を通って延設される。 Furthermore, in each of the power receiving and transforming equipment units 50, one set of busbars 36A (or 36B) connects the transformer secondary side portion 22, the busbar connection portion 15A (or busbar connection portion 15B), the station transformer portion 16, and a plurality of wiring lines. Wire portion 17 is electrically connected. In each of the power receiving and transforming equipment units 50, the transformer secondary side portion 22, the busbar connecting portion 15A (or the busbar connecting portion 15B), the station transformer portion 16, and the plurality of distribution line portions 17 are partitioned from each other. Therefore, the busbar 36A (or 36B) extends through the inside of the frame 51.
例えば、変圧器二次側部分２２、母線連絡部分１５Ａ、所内変圧部分１６及び複数の配電線部分１７のそれぞれが鉄の筐体に収納される構成、すなわち、複数のキュービクルが設けられる構成では、複数のキュービクルのそれぞれに対して１組ずつ母線が設けられる。そして、鉄の筐体の外部において、接続部材等を介して、複数の母線の間が接続され、複数のキュービクルの間が電気的に接続される。実施形態では、前述のように受変電機器ユニット５０が形成されるため、母線連絡部分１５Ａ（又は母線接続部分１５Ｂ）、所内変圧部分１６及び複数の配電線部分１７を母線３６Ａ（又は３６Ｂ）によって接続する構成は、複数のキュービクルが設けられる構成とは、異なる。 For example, in a configuration in which the transformer secondary side portion 22, the busbar connection portion 15A, the station transformer portion 16, and the plurality of distribution line portions 17 are each housed in an iron casing, that is, in a configuration in which a plurality of cubicles are provided, One set of busbars is provided for each of the plurality of cubicles. Then, outside the iron casing, the plurality of bus bars are connected via connection members or the like, and the plurality of cubicles are electrically connected. In the embodiment, since the power receiving and transforming equipment unit 50 is formed as described above, the busbar connecting portion 15A (or busbar connecting portion 15B), the station transformer portion 16, and the plurality of distribution line portions 17 are connected by the busbar 36A (or 36B). The configuration for connecting is different from the configuration in which multiple cubicles are provided.
また、母線３６Ａ，３６Ｂは、アルミニウム及び銅等の導電材料から形成可能である。ただし、母線３６Ａ，３６Ｂを軽量化する観点から、母線３６Ａ，３６Ｂは、アルミニウムから形成されることが好ましい。また、受変電機器ユニット５０のそれぞれでは、フレーム５１によって形成される前方側の面は、不燃性を有する透明なカバーから形成されることが好ましい。この場合、受変電機器ユニット５０の前方側の面のカバーは、例えば、ポリカーボネート等から形成される。受変電機器ユニット５０において前方側の面が透明に形成されることにより、受変電機器ユニット５０において一体に組付けられる受変電機器の状態を、前方側から視認可能となる。また、受変電機器ユニット５０では、一体に組付けられる受変電機器等は、前方側の面のカバー等によって、受変電機器ユニット５０の外部に露出しない。 Additionally, bus bars 36A and 36B can be formed from conductive materials such as aluminum and copper. However, from the viewpoint of reducing the weight of the bus bars 36A, 36B, the bus bars 36A, 36B are preferably formed from aluminum. Further, in each of the power receiving and transforming equipment units 50, the front side surface formed by the frame 51 is preferably formed from a nonflammable transparent cover. In this case, the cover on the front side of the power receiving and transforming equipment unit 50 is made of, for example, polycarbonate. By forming the front side surface of the power receiving and transforming equipment unit 50 to be transparent, the state of the power receiving and transforming equipment assembled together in the power receiving and transforming equipment unit 50 can be visually confirmed from the front side. Further, in the power receiving and transforming equipment unit 50, the power receiving and transforming equipment etc. that are assembled together are not exposed to the outside of the power receiving and transforming equipment unit 50 due to a cover on the front side surface or the like.
図８は、受変電設備１において建屋３を形成する複数のコンテナハウスの図６とは別の１つであるコンテナハウスＣ２の内部構成を示す。図３、図４及び図８に示すように、受変電設備１のそれぞれでは、コンテナハウスＣ２の内部に、配電盤ユニット６０が配置及び収納される。したがって、コンテナハウスＣ２は、配電盤ユニット６０が収納される配電盤用ハウスとなる。 FIG. 8 shows the internal configuration of a container house C2, which is one of the plurality of container houses forming the building 3 in the power receiving and transforming equipment 1, which is different from that shown in FIG. As shown in FIGS. 3, 4, and 8, in each of the power receiving and transforming equipment 1, a switchboard unit 60 is arranged and housed inside the container house C2. Therefore, the container house C2 becomes a house for a power distribution board in which the power distribution board unit 60 is housed.
図８等に示すように、受変電設備１のそれぞれにおいてコンテナハウスＣ２に収納される配電盤ユニット６０では、複数の配電盤が、１つのフレーム６１に一体に組付けられ、１つのフレーム６１の内部に一括して収納される。したがって、配電盤ユニット６０では、複数の配電盤のそれぞれが筐体に収納される構成とは異なり、複数の配電盤は、壁等によって互いに対して隔壁されず、互いに対して分離されていない。すなわち、配電盤ユニット６０では、複数の配電盤が、互いに対して隔壁されることなく、フレーム６１に一体に組付けられる。そして、受変電設備１のそれぞれでは、配電盤用ハウスであるコンテナハウスＣ２の内部に、装置群１０の一部を構成する複数の配電盤が互に対して隔壁されることなく一体に組付けられた配電盤ユニット６０が、収納される。 As shown in FIG. 8 etc., in the switchboard unit 60 housed in the container house C2 in each of the power receiving and transforming equipment 1, a plurality of switchboards are assembled into one frame 61, and are housed inside the one frame 61. Stored all at once. Therefore, in the switchboard unit 60, unlike a configuration in which each of the plurality of switchboards is housed in a housing, the plurality of switchboards are not partitioned from each other by a wall or the like and are not separated from each other. That is, in the switchboard unit 60, a plurality of switchboards are integrally assembled to the frame 61 without being partitioned from each other. In each of the power receiving and transforming equipment 1, a plurality of switchboards constituting a part of the device group 10 are integrally assembled inside the container house C2, which is a switchboard house, without being partitioned from each other. A switchboard unit 60 is housed.

A control protection device (transformer panel) 65 that performs monitoring and control in addition to protecting the equipment for the transformer section 11 including the transformer section 11, and a control protection device (transformer panel) 65 that performs monitoring, control, etc. in addition to protecting the equipment for the plurality of distribution line sections 17. (distribution line board) 66, an in-station panel 67 that monitors and controls the in-station transformer section 16 in addition to protecting equipment, and an interface device 68 that controls information transmission.
また、配電盤ユニット６０では、 高さ方向、高さ方向に対して交差する（直交又は略直交する）前後方向、高さ方向及び前後方向の両方に対して交差する（直交又は略直交する）幅方向が、規定される。図８の一例では、受変電設備１Ａ，１Ｂのそれぞれにおいて、配電盤ユニット６０は、前後方向が建屋３の奥行方向と一致又は略一致し、かつ、幅方向が建屋３の横方向と一致又は略一致する状態で、コンテナハウスＣ２に設置される。そして、配電盤ユニット６０は、高さ方向が建屋３の高さ方向と一致又は略一致する状態で、コンテナハウスＣ２の内部に収納される。また、配電盤ユニット６０のそれぞれでは、保護リレー装置６２、監視制御装置６３、制御保護装置６５，６６、所内盤６７及びインタフェース装置６８が、幅方向（建屋３の横方向）に並んで配置される。 In addition, in the switchboard unit 60, the height direction, the front-back direction that intersects (orthogonally or approximately orthogonally to) the height direction, and the width that intersects (orthogonally or approximately orthogonally) to both the height direction and the front-rear direction. A direction is defined. In the example of FIG. 8, in each of the power receiving and transforming facilities 1A and 1B, the switchboard unit 60 has a front-rear direction that matches or substantially matches the depth direction of the building 3, and a width direction that matches or substantially matches the lateral direction of the building 3. They are installed in container house C2 in a matching state. The switchboard unit 60 is housed inside the container house C2 with its height direction matching or substantially matching the height direction of the building 3. Further, in each of the switchboard units 60, a protection relay device 62, a supervisory control device 63, control protection devices 65, 66, an in-house panel 67, and an interface device 68 are arranged side by side in the width direction (lateral direction of the building 3). .
また、受変電設備１Ａにおいて建屋３を構成するコンテナハウスＣ３には、電気所において受変電設備１Ａ，１Ｂで共用される装置（共通盤）が、収納される。受変電設備１Ａでは、コンテナハウスＣ３の内部に収納される装置も、建屋３の内部に収納される前述の装置群１０の一部を構成する。コンテナハウスＣ３に収納される装置としては、複数の受変電設備１についての情報を一括して送受信する通信機器、及び、複数の受変電設備１で共用される電源等が、挙げられる。なお、図３の一例では、コンテナハウスＣ３の内部に、複数の受変電設備１で共用される装置が一体に組付けられた共通盤７０も設置可能とする。 Furthermore, a container house C3 that constitutes the building 3 in the power receiving and transforming equipment 1A houses a device (common panel) that is shared by the power receiving and transforming equipment 1A and 1B at the electric station. In the power receiving and transforming equipment 1A, the devices housed inside the container house C3 also constitute a part of the above-mentioned device group 10 housed inside the building 3. Devices housed in the container house C3 include a communication device that collectively transmits and receives information about the plurality of power receiving and transforming facilities 1, a power source that is shared by the plurality of power receiving and transforming facilities 1, and the like. In the example of FIG. 3, a common panel 70 in which devices shared by a plurality of power receiving and transforming facilities 1 are assembled can also be installed inside the container house C3.
前述のような受変電設備１を建設する際には、製造メーカの工場等の電気所の外部において、複数の受変電機器及び複数の配電盤を含む複数の装置を、複数のコンテナハウスＣに分割して設置する。この際、例えば、コンテナハウスＣ１に、受変電機器ユニット５０が設置され、コンテナハウスＣ２に、配電盤ユニット６０が設置される。そして、コンテナハウスＣを電気所に搬送する前に、可能な範囲で必要な配線を行い、複数の装置を電気的に接続する。そして、コンテナハウスＣを電気所に搬送する前に、製造メーカの工場等で、複数の装置の性能試験を可能な範囲で行う。この際、例えば、コンテナハウスＣ１に設置された受変電機器とコンテナハウスＣ２に設置された配電盤との間を電気的に接続する等して、性能試験が行われる。 When constructing the power receiving and transforming equipment 1 as described above, a plurality of devices including a plurality of power receiving and transforming equipment and a plurality of switchboards are divided into a plurality of container houses C outside an electric station such as a manufacturer's factory. and install it. At this time, for example, the power receiving and transforming equipment unit 50 is installed in the container house C1, and the power distribution board unit 60 is installed in the container house C2. Then, before transporting the container house C to an electrical station, necessary wiring is performed to the extent possible and a plurality of devices are electrically connected. Then, before transporting the container house C to an electrical station, performance tests of a plurality of devices are performed to the extent possible at the manufacturer's factory or the like. At this time, a performance test is performed, for example, by electrically connecting the power receiving and transforming equipment installed in the container house C1 and the power distribution board installed in the container house C2.
そして、複数の装置が分割されて設置された複数のコンテナハウスＣを、互いに対して分離された状態で、電気所に搬送する。図９は、複数のコンテナハウスＣのある１つを搬送している状態を示す。図９に示すように、電気所への複数のコンテナハウスＣの搬送では、１台のトレーラ８０に１つのコンテナハウスＣを搭載して、搬送が行われる。このため、搬送するコンテナハウスＣと同一の台数のトレーラ８０を用いて、搬送が行われる。また、コンテナハウスＣのそれぞれは、１台のトレーラ８０に１つのコンテナハウスＣが搭載可能な大きさに、形成される。したがって、１台のトレーラ８０に１つのコンテナハウスＣが搭載可能な大きさに、建屋３が複数のコンテナハウスＣに分割される。なお、図９では、コンテナハウスＣの内部に設置される装置を省略して示す。 Then, a plurality of container houses C in which a plurality of devices are installed are separated from each other and transported to an electrical station. FIG. 9 shows a state in which one of the plurality of container houses C is being transported. As shown in FIG. 9, when transporting a plurality of container houses C to an electric station, one container house C is loaded onto one trailer 80 and transported. Therefore, transportation is performed using the same number of trailers 80 as the number of container houses C to be transported. Moreover, each of the container houses C is formed to a size that allows one container house C to be mounted on one trailer 80. Therefore, the building 3 is divided into a plurality of container houses C to a size that allows one container house C to be loaded onto one trailer 80. Note that in FIG. 9, devices installed inside the container house C are omitted.
受変電設備１の建設では、電気所の敷地内において、基礎工事を行った後に、架台２を建設する。そして、前述のようにして電気所に搬送された複数のコンテナハウスＣを、架台２上に設置する。そして、架台２上において、複数のコンテナハウスＣを互いに対して結合する。これにより、建屋３が組立てられるとともに、建屋３の内部に、複数の受変電機器及び複数の配電盤を含む複数の装置が、収納される。そして、発電所等から電力を供給する電力系統に、建設した受変電設備１を連系することにより、受変電設備１の運用が開始される。なお、架台２は、必ずしも設けられる必要はなく、地盤上において、複数のコンテナハウスＣを互いに対して結合し、建屋３が組立ててもよい。 In constructing the power receiving and transforming equipment 1, the pedestal 2 is constructed after foundation work is performed within the premises of the electric station. Then, the plurality of container houses C transported to the electrical station as described above are installed on the pedestal 2. Then, on the frame 2, the plurality of container houses C are coupled to each other. As a result, the building 3 is assembled, and a plurality of devices including a plurality of power receiving and transforming devices and a plurality of switchboards are housed inside the building 3. Then, the operation of the power receiving and transforming equipment 1 is started by interconnecting the constructed power receiving and transforming equipment 1 to an electric power system that supplies electric power from a power plant or the like. Note that the frame 2 does not necessarily need to be provided, and the building 3 may be assembled by connecting a plurality of container houses C to each other on the ground.
ここで、電気所の敷地内において土木工事及び建築工事によって建屋を建築した後に、複数の装置を電気所に搬送し、搬送された複数の装置を建築した建屋の内部に収納する場合を、比較例とする。実施形態では、複数のコンテナハウスＣを互いに対して結合することにより建屋３が組付けられるため、比較例に比べて、建屋３を建設する手間が低減され、短時間で建屋３が建設される。また、複数のコンテナハウスＣに複数の装置が分割して設置された状態で複数のコンテナハウスＣが互い対して結合されるため、建屋３の組立てと並行して、建屋３の内部への複数の装置が収納される。すなわち、実施形態は、建屋を建築した後に、建築した建屋の内部に複数の装置を設置する比較例とは、異なる。このため、建屋３の内部に複数の装置を設置する手間等が低減される。 Here, we will compare the case where, after constructing a building through civil engineering and construction work on the premises of an electric power station, multiple devices are transported to the electric power station, and the transported multiple devices are stored inside the constructed building. Take as an example. In the embodiment, the building 3 is assembled by connecting a plurality of container houses C to each other, so the effort to construct the building 3 is reduced compared to the comparative example, and the building 3 can be constructed in a short time. . In addition, since a plurality of container houses C are connected to each other with a plurality of devices installed separately in a plurality of container houses C, in parallel with the assembly of the building 3, multiple devices are installed inside the building 3. equipment is housed. That is, the embodiment is different from the comparative example in which a plurality of devices are installed inside the constructed building after the building is constructed. Therefore, the effort of installing a plurality of devices inside the building 3 is reduced.
また、実施形態では、複数の装置が分割されて設置された複数のコンテナハウスＣを、互いに対して分離された状態で、電気所に搬送する。このため、複数の装置のそれぞれを電気所に搬送してから建屋の内部に設置する比較例等と比べて、実施形態では、複数の受変電機器及び複数の配電盤を含む複数の装置を電気所へ搬送する手間及びコスト等が、低減される。また、実施形態では、コンテナハウスＣ及び複数の装置を電気所に搬送する前に、必要な配線が行われるとともに、複数の装置の性能試験を可能な範囲で行う。このため、電気所において建屋３の内部に複数の装置が設置した後において、配線作業及び性能試験に要する手間及び時間等が、低減される。以上のように実施形態では、比較例等に比べて、受変電設備１の建設における手間が低減され、受変電設備１の建設に要する工期が短縮される。 Further, in the embodiment, a plurality of container houses C in which a plurality of devices are installed separately are transported to an electrical station in a state where they are separated from each other.

Furthermore, since no iron casing is provided, the space occupied by the power receiving and transforming equipment unit 50 inside the building 3 can be saved. Further, in the embodiment, parts such as through bushings that connect the plurality of cubicles are not necessary. This reduces the number of parts used and also reduces costs.
また、実施形態の受変電機器ユニット５０では、複数の受変電機器は、互いに対して隔壁されていない。このため、受変電機器ユニット５０では、１組の母線３６Ａ（又は３６Ｂ）によって、変圧器二次側部分２２及び配電線部分１７等の複数の部分が、電気的に接続される。このため、複数のキュービクルが設けられる構成に比べて、母線の本数を削減可能であり、母線同士を接続する箇所を削減可能となる。また、受変電機器ユニット５０を設けることにより、母線３６Ａ（又は３６Ｂ）を外部に露出させることなく、変圧器二次側部分２２及び配電線部分１７等の複数の部分が、母線３６Ａ（又は３６Ｂ）によって電気的に接続される。また、実施形態では、複数の受変電機器の間を連結する貫通ブッシング等の部品が、不要となる。これにより、使用部品が削減されるとともに、コストも削減可能なる。 Moreover, in the power receiving and transforming equipment unit 50 of the embodiment, the plurality of power receiving and transforming equipments are not partitioned from each other. Therefore, in the power receiving and transforming equipment unit 50, a plurality of parts such as the transformer secondary part 22 and the distribution line part 17 are electrically connected by one set of bus bars 36A (or 36B). Therefore, compared to a configuration in which a plurality of cubicles are provided, the number of bus bars can be reduced, and the locations where the bus bars are connected can be reduced. Furthermore, by providing the power receiving and transforming equipment unit 50, multiple parts such as the transformer secondary side part 22 and the distribution line part 17 can be connected to the bus bar 36A (or 36B) without exposing the bus bar 36A (or 36B) to the outside. ) are electrically connected. Further, in the embodiment, parts such as a through bushing that connects a plurality of power receiving and transforming devices are not required. This reduces the number of parts used and also reduces costs.
また、実施形態では、配電盤用ハウスであるコンテナハウスＣ２の内部に、複数の配電盤が互に対して隔壁されることなく一体に組付けられた配電盤ユニット６０が、収納される。このため、複数の配電盤のそれぞれが筐体に収納される構成に比べて、実施形態の構成では、筐体が設けられないことに起因して、軽量化される。また、筐体が設けられないことにより、建屋３の内部において配電盤ユニット６０が占めるスペースを、省スペース化可能となる。また、機能別にユニット単位で配電盤が配置されるため、配電盤ユニット６０の使用を開始した後において、配電盤ユニット６０の部分的な更新を容易に行うことが可能になる。 Further, in the embodiment, a power distribution board unit 60 in which a plurality of power distribution boards are assembled together without being separated from each other is housed inside a container house C2 which is a house for a power distribution board. Therefore, compared to a configuration in which each of the plurality of switchboards is housed in a casing, the configuration of the embodiment is lighter in weight because no casing is provided. Furthermore, since no casing is provided, the space occupied by the switchboard unit 60 inside the building 3 can be saved. Furthermore, since the switchboards are arranged in units according to functions, it is possible to easily partially update the switchboard unit 60 after the switchboard unit 60 has started to be used.
また、実施形態のある一例の受変電設備１では、電気所の立地条件に対応させて、架台２上に、建屋３が設置される。このため、積雪、大雨による浸水、及び、津波等に対して、適切に対策が行われる。また、受変電設備１の建設において、想定される浸水の深さ等に対応させて、高さ方向に沿った架台２の寸法を、適宜に調整可能である。 Further, in the power receiving and transforming equipment 1 of one example of the embodiment, a building 3 is installed on the pedestal 2 in accordance with the location conditions of the electric station. For this reason, appropriate measures are taken against snow accumulation, flooding due to heavy rain, tsunamis, etc. Furthermore, in constructing the power receiving and transforming equipment 1, the dimensions of the pedestal 2 along the height direction can be adjusted as appropriate in accordance with the assumed depth of flooding and the like.
また、実施形態の一例では、建屋３の内部に収納される受変電機器ユニット５０及び配電盤ユニット６０等は、前面保守であること、すなわち、前方側からのみ点検等が可能である。また、前述した一例では、受変電機器ユニット５０において前方側の面が透明に形成されることにより、受変電機器ユニット５０において一体に組付けられる受変電機器の状態を、前方側から視認可能となる。このため、前面保守の構成において、受変電機器ユニット５０の点検等を、適切かつ容易に行うことが可能となる。また、受変電機器ユニット５０の前方側の面がカバーで覆われ、受変電機器が外部に露出しないため、主回路に配置される受変電機器への作業者等の接触が、有効に防止される。 Furthermore, in one example of the embodiment, the power receiving and transforming equipment unit 50, the switchboard unit 60, etc. that are housed inside the building 3 are maintained from the front, that is, they can be inspected only from the front side. Furthermore, in the above-mentioned example, the front surface of the power receiving and transforming equipment unit 50 is formed to be transparent, so that the state of the power receiving and transforming equipment assembled integrally in the power receiving and transforming equipment unit 50 can be visually checked from the front side. Become. Therefore, in the front maintenance configuration, it is possible to appropriately and easily perform inspections of the power receiving and transforming equipment unit 50. Furthermore, since the front side of the power receiving and transforming equipment unit 50 is covered with a cover and the power receiving and transforming equipment is not exposed to the outside, it is effectively prevented that workers etc. come into contact with the power receiving and transforming equipment arranged in the main circuit. Ru.
また、電気所では、建屋３の内部の装置と建屋３の外部の装置との間を接続するケーブルは、建屋３から外部に延出される。受変電設備１では、電力ケーブル及び制御ケーブルを含むケーブルは、前面の上部に配置する等して、建屋３の床面に貫通孔及びダクト等を形成することなく、建屋３の外部に延出されることが、好ましい。ある一例では、コンテナハウスＣのいずれかの側壁の外表面に、Ｔ型のゴムモールドによる終端接続部が形成され、建屋３の内部の装置と建屋３の外部の装置との間を接続するケーブルは、終端接続部を介して、建屋３から外部に延出される。 Furthermore, in the electrical station, cables that connect devices inside the building 3 and devices outside the building 3 are extended from the building 3 to the outside. In the power receiving and transforming equipment 1, cables including power cables and control cables are placed at the top of the front surface, and are extended to the outside of the building 3 without forming through holes or ducts on the floor of the building 3. It is preferable that In one example, a T-shaped rubber molded terminal connection part is formed on the outer surface of one of the side walls of the container house C, and a cable connecting equipment inside the building 3 and equipment outside the building 3 is formed. is extended from the building 3 to the outside via the terminal connection.
浸水対策等で床面に貫通孔等を形成しないため、建屋３の内部の装置と建屋３の外部の装置との間を接続する作業の作業性が、向上する。また、床面からケーブルを建屋３の外部に延出させないため、建屋３の内部の装置と建屋３の外部の装置とを接続するケーブルにおいて、導電部分の露出を防止可能となる。これにより、作業等における安全性が、向上する。また、床面に貫通孔等が形成されないことにより、建屋３の内部への小動物の侵入等が、有効に抑制される。 Since through-holes and the like are not formed in the floor surface to prevent flooding, etc., the workability of connecting equipment inside the building 3 and equipment outside the building 3 is improved. Further, since the cable is not extended from the floor to the outside of the building 3, it is possible to prevent the conductive portion of the cable connecting the equipment inside the building 3 and the equipment outside the building 3 from being exposed. This improves safety during work and the like. Furthermore, since no through holes are formed in the floor surface, entry of small animals into the interior of the building 3 is effectively suppressed.
また、建屋３の内部に配置される装置、すなわち、装置群１０を構成する装置へのケーブルの接続は、原則的にはコネクタ接続であることが好ましい。これにより、ケーブルの設置作業及び接続作業における手間等が、さらに低減される。 In principle, it is preferable that cables be connected to devices disposed inside the building 3, that is, devices constituting the device group 10, by connector connections. This further reduces the effort involved in cable installation and connection work.
建屋３の内部の装置と建屋３の外部の装置との間を接続する制御ケーブルは、中継端子台を経由して延設されることが、好ましい。この場合、外部からのサージを対策する構成が、中継端子台に設けられることが、保安上好ましい。 It is preferable that the control cable connecting the device inside the building 3 and the device outside the building 3 be extended via a relay terminal block. In this case, it is preferable from the viewpoint of safety that the relay terminal block is provided with a structure that takes measures against surges from the outside.
