Description

本発明は、高電圧モータ等を起動するための高圧コンビネーションスタータ盤に収納される高圧真空電磁接触器に関し、特に高圧ヒューズの配置構造を工夫した高圧真空電磁接触器に関する。   The present invention relates to a high-pressure vacuum electromagnetic contactor housed in a high-voltage combination starter panel for starting a high-voltage motor or the like, and more particularly to a high-pressure vacuum electromagnetic contactor with a devised arrangement structure of a high-voltage fuse.

図２は従来の高圧真空電磁接触器（ＶＣＳ）の構成を示し、（ａ）は高圧コンビネーションスタータ盤内に収納されたＶＣＳの側面図、（ｂ）はＶＣＳの正面図である。なお、（ａ）の右側がＶＣＳの正面である。
高圧コンビネーションスタータ盤（単に、盤とも略す）１０は、縦型の直方体形状を成し、内部に接地金属を兼ねる２枚の仕切り板１１が水平に配設されてユニット室に区切られている。このうち上段と中段のユニット室にＶＣＳ１２が、車輪１３を介して前後に移動可能に収納されている。 2A and 2B show a configuration of a conventional high-pressure vacuum electromagnetic contactor (VCS), in which FIG. 2A is a side view of the VCS housed in the high-pressure combination starter panel, and FIG. 2B is a front view of the VCS. The right side of (a) is the front of the VCS.
The high-pressure combination starter board (simply abbreviated as a board) 10 has a vertical rectangular parallelepiped shape, and two partition plates 11 that also serve as a ground metal are disposed horizontally and partitioned into unit chambers. Among these, the VCS 12 is accommodated in the upper and middle unit chambers so as to be movable back and forth via the wheels 13.

ＶＣＳ１２は、概略直方体形のフレームであるクレードル２１を有し、この中に、電磁開閉接点である真空バルブが収納された真空バルブ用絶縁ケース（単に、絶縁ケースとも略す）２２と、操作電源トランス２３とが配置され、これら上部に高圧ヒューズ２４が配置され、これらの要素２２，２３，２４が導体を介して電気的に接続されている。この電気経路には、破線矢印Ｙ１で示すように図示せぬ電源電圧からの電流ｉが、高圧ヒューズ２４、絶縁ケース２２内の真空バルブの順に流れるようになっている。   The VCS 12 includes a cradle 21 that is a substantially rectangular parallelepiped frame, in which a vacuum valve insulation case (simply abbreviated as an insulation case) 22 in which a vacuum valve as an electromagnetic switching contact is housed, and an operation power transformer 23, a high-voltage fuse 24 is disposed on the upper portion thereof, and these elements 22, 23, and 24 are electrically connected through conductors. A current i from a power supply voltage (not shown) flows through this electrical path in the order of the high-voltage fuse 24 and the vacuum valve in the insulating case 22 as indicated by a broken line arrow Y1.

高圧ヒューズ２４は、真空バルブの開閉で対応しきれない程の大きな短絡電流が流れた場合に電流経路を遮断するものである。
また、ＶＣＳ１２の正面保護カバー２５には、両側に把手２６とインターロックレバー２７が設けられている。その把手２６を矢印Ｙ２で示す前後方向に人が把持してＶＣＳ１２を移動することが可能となっている。 The high-voltage fuse 24 cuts off the current path when a large short-circuit current that cannot be dealt with by opening / closing the vacuum valve flows.
Further, the front protective cover 25 of the VCS 12 is provided with a handle 26 and an interlock lever 27 on both sides. A person can hold the handle 26 in the front-rear direction indicated by the arrow Y2 to move the VCS 12.

ＶＣＳ１２の試験を行う場合、インターロックレバー２７でインターロックを解除した後、矢印Ｙ２で示す右側の引き出し方向に試験／断路位置Ｐ１まで引き出す。
また、高圧ヒューズ２４を交換する場合は、その試験／断路位置Ｐ１から更に矢印Ｙ２の右方向に引き出し、ＶＣＳ１２を盤１０の外側に引き出してから行う。これは高圧ヒューズ２４がＶＣＳ１２の内部上方に配置されているので、少なくとも高圧ヒューズ２４の保護カバーを開けることが可能な位置までＶＣＳ１２を盤１０から引き出す必要性による。 When the VCS 12 test is performed, the interlock lever 27 is used to release the interlock, and then it is pulled out to the test / disconnection position P1 in the right pulling direction indicated by the arrow Y2.
Further, when the high-voltage fuse 24 is replaced, the high-pressure fuse 24 is further pulled out from the test / disconnection position P1 in the right direction of the arrow Y2, and the VCS 12 is pulled out to the outside of the panel 10. This is because the high-voltage fuse 24 is disposed above the inside of the VCS 12, so that it is necessary to pull out the VCS 12 from the panel 10 to a position where at least the protective cover of the high-voltage fuse 24 can be opened.

この種の従来の高圧真空電磁接触器として、例えば特許文献１及び２に記載のものがあり、これらに代表されるように、従来の高圧真空電磁接触器は上述したように高圧ヒューズが装置上方に配置されている。
特開昭５８−７９４１０号公報 特開平５−１９００５９号公報 As this type of conventional high-pressure vacuum electromagnetic contactor, for example, there are those described in Patent Documents 1 and 2, and as typified by them, the conventional high-pressure vacuum electromagnetic contactor has a high-voltage fuse located above the device as described above. Is arranged.
JP 58-79410 A JP-A-5-190059

しかし、従来の高圧真空電磁接触器においては、高圧ヒューズ２４を交換する場合、ＶＣＳ１２を盤１０の外側に引き出してから交換しなければならないが、この際、ＶＣＳ１２は人が持てないほど重く、特に多段積収納した場合、盤１０の２段目、３段目等に収納されていると、人力で盤１０の外側に引き出すのは危険が伴う。そこで、リフタ３０を使用し、このリフタ３０の水平把持部にＶＣＳ１２を載置して引き出し、高圧ヒューズ２４を交換する。交換後は逆の手順でＶＣＳ１２を盤１０に収納する。
このようなリフタ３０を用いた手順が必要なので、高圧ヒューズ２４を交換するために手間が掛かるという問題がある。
本発明は、このような課題に鑑みてなされたものであり、高圧ヒューズを容易に交換することができる高圧真空電磁接触器を提供することを目的としている。 However, in the conventional high-pressure vacuum electromagnetic contactor, when the high-voltage fuse 24 is replaced, the VCS 12 must be replaced after being pulled out of the panel 10, and at this time, the VCS 12 is too heavy for a person to hold. When stored in multiple stages, if it is stored in the second, third, etc. of the board 10, it is dangerous to pull it out of the board 10 manually. Therefore, the lifter 30 is used, the VCS 12 is placed on the horizontal gripping portion of the lifter 30 and pulled out, and the high-voltage fuse 24 is replaced. After the replacement, the VCS 12 is stored in the panel 10 in the reverse procedure.
Since such a procedure using the lifter 30 is necessary, there is a problem that it takes time to replace the high-voltage fuse 24.
This invention is made | formed in view of such a subject, and it aims at providing the high voltage | pressure vacuum electromagnetic contactor which can replace | exchange a high voltage fuse easily.

上記目的を達成するために、本発明の請求項１による高圧真空電磁接触器は、高圧コンビネーションスタータ盤に収納され、所定以上の電流が流れた際に電路を遮断するための高圧ヒューズを有する高圧真空電磁接触器において、前記高圧ヒューズを、前記高圧コンビネーションスタータ盤の正面側位置に着脱自在に配置したことを特徴とする。
この構成によれば、高圧ヒューズが高圧コンビネーションスタータ盤の正面側位置に配置されているので、高圧ヒューズを交換する際に、高圧真空電磁接触器を盤から通常設定されている試験／断路位置に引き出し、この位置で交換することができる。従来は、リフタに高圧真空電磁接触器を載置して盤から引き出し、高圧真空電磁接触器を床まで下ろしてから高圧ヒューズを交換していた。そして、交換後は逆の手順で高圧真空電磁接触器を盤に収納しなければならなかったので、リフタを用いた手間が掛かる手順を必要としていたが、本発明では、上記のように、盤から引き出さずとも試験／断路位置で交換可能なので、従来に比べ高圧ヒューズを容易に交換することができる。 In order to achieve the above object, a high voltage vacuum electromagnetic contactor according to claim 1 of the present invention is housed in a high voltage combination starter panel and has a high voltage fuse having a high voltage fuse for interrupting an electric circuit when a predetermined current or more flows. In the vacuum electromagnetic contactor, the high-voltage fuse is detachably disposed at a front side position of the high-voltage combination starter panel.
According to this configuration, since the high voltage fuse is arranged at the front side position of the high voltage combination starter panel, when replacing the high voltage fuse, the high voltage vacuum electromagnetic contactor is moved from the panel to the normally set test / disconnection position. The drawer can be replaced in this position. Conventionally, a high-pressure vacuum electromagnetic contactor is placed on a lifter and pulled out from the panel, and the high-pressure vacuum electromagnetic contactor is lowered to the floor before the high-pressure fuse is replaced. And since the high-pressure vacuum electromagnetic contactor had to be housed in the panel in reverse order after the replacement, a procedure that took time and effort using the lifter was necessary, but in the present invention, as described above, Since it can be exchanged at the test / disconnection position without being pulled out from, the high-voltage fuse can be easily exchanged as compared with the conventional case.

また、本発明の請求項２による高圧真空電磁接触器は、請求項１において、前記高圧ヒューズは、前記高圧コンビネーションスタータ盤の正面側が開口し、この開口に開閉自在な扉状の保護カバーが配設された絶縁ケースに収納され、この収納時に当該絶縁ケースを突き出て電源に接続された導体に繋がる第１の接点と、当該絶縁ケースを突き出て真空バルブに接続された導体に繋がる第２の接点とに両端が電気的に接続され、これら接続箇所以外が他の導電部分と絶縁されるように当該絶縁ケースに収納されていることを特徴とする。
この構成によれば、高圧ヒューズを、保護カバーを盤正面側から開けることにより容易に交換することができる。 The high-pressure vacuum electromagnetic contactor according to claim 2 of the present invention is the high-pressure vacuum electromagnetic contactor according to claim 1, wherein the high-voltage fuse has an opening on the front side of the high-voltage combination starter panel, and a door-shaped protective cover that can be opened and closed is disposed in the opening. A first contact that is housed in an insulating case provided and protrudes from the insulation case to the conductor connected to the power source during the storage; and a second contact that protrudes from the insulation case and connected to the conductor connected to the vacuum valve. It is characterized in that both ends are electrically connected to the contact and are housed in the insulating case so as to be insulated from other conductive portions other than the connected portions.
According to this configuration, the high-voltage fuse can be easily replaced by opening the protective cover from the front side of the panel.

以上説明したように本発明の高圧真空電磁接触器によれば、高圧ヒューズを容易に交換することができるという効果がある。   As described above, according to the high-pressure vacuum electromagnetic contactor of the present invention, there is an effect that the high-pressure fuse can be easily replaced.

以下、本発明の実施の形態を、図面を参照して説明する。但し、本明細書中の全図において相互に対応する部分には同一符号を付し、重複部分においては後述での説明を適時省略する。
図１は、本発明の実施の形態に係る高圧真空電磁接触器（ＶＣＳ）の構成を示し、（ａ）は高圧コンビネーションスタータ盤内に収納されたＶＣＳの側面図、（ｂ）はＶＣＳの背面図である。
図１に示すＶＣＳ４０が、図２に示した従来のＶＣＳ１２と異なる点は、高圧ヒューズ２４をＶＣＳ４０における盤１０の正面側位置に着脱自在に配置したことにある。但し、本実施の形態では、高圧ヒューズ２４を水平な仕切り板１１に対して垂直状態に配置したが、盤１０の正面側位置であれば、それ以外に、水平や斜めなど自由な状態に配置してもよい。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, parts corresponding to each other in all the drawings in this specification are denoted by the same reference numerals, and description of the overlapping parts will be omitted as appropriate.
FIG. 1 shows a configuration of a high-pressure vacuum electromagnetic contactor (VCS) according to an embodiment of the present invention, where (a) is a side view of the VCS housed in a high-pressure combination starter panel, and (b) is the back side of the VCS. FIG.
The VCS 40 shown in FIG. 1 is different from the conventional VCS 12 shown in FIG. 2 in that the high-voltage fuse 24 is detachably arranged at the front side position of the panel 10 in the VCS 40. However, in the present embodiment, the high-voltage fuse 24 is arranged in a vertical state with respect to the horizontal partition plate 11. However, if it is a front side position of the panel 10, it is arranged in a free state such as horizontal or diagonal. May be.

高圧ヒューズ２４は、箱型の高圧ヒューズ用絶縁ケース（単に、絶縁ケースとも略す）４１に収納されている。絶縁ケース４１は、盤１０の正面側が開口しており、この開口に開閉自在な扉状の保護カバー４２が配設されている。絶縁ケース４１の背面板の上方には図示せぬ電源に接続された導体４３の一部が外面から内面に突出して第１の接点４３ａとして配設され、下方には三相の真空バルブ４４に接続された導体４５が外面から内面に突出して第２の接点４５ａとして配設されている。   The high-voltage fuse 24 is housed in a box-shaped insulation case for high-voltage fuse (simply abbreviated as an insulation case) 41. The insulating case 41 has an opening on the front side of the panel 10, and a door-shaped protective cover 42 that can be opened and closed is disposed in the opening. Above the back plate of the insulating case 41, a part of the conductor 43 connected to a power source (not shown) protrudes from the outer surface to the inner surface and is arranged as a first contact 43a, and below the three-phase vacuum valve 44 The connected conductor 45 projects from the outer surface to the inner surface and is disposed as a second contact 45a.

高圧ヒューズ２４は、第１及び第２の接点４３ａ，４５ａに一端及び他端が電気的に接続され、これら接続箇所以外が他の導電部分と絶縁されるように絶縁ケース４１に収納されている。この収納された高圧ヒューズ２４は、保護カバー４１を盤１０の正面側から開けることにより、従来構成のようにＶＣＳ４０を盤１０の外側に引き出さずとも、交換できるようになっている。   The high-voltage fuse 24 is housed in an insulating case 41 so that one end and the other end are electrically connected to the first and second contacts 43a and 45a, and the other portions are insulated from other conductive portions. . The housed high-voltage fuse 24 can be replaced by opening the protective cover 41 from the front side of the panel 10 without pulling the VCS 40 out of the panel 10 as in the conventional configuration.

真空バルブ４４は、当該真空バルブ４４の接点圧力を与える圧接バネ４７と、真空バルブ４４を駆動する駆動軸４８と、圧接バネ４７を介して駆動軸４８をマグネットで駆動する操作部４９とを備えて構成されている。本例では操作部４９は横に配置されているが、スペースがあればどこに配置しても良い。
また、真空バルブ４４に接続された導体５１は、環状の電流センサ５２の中空部分を通って電源に接続されている。 The vacuum valve 44 includes a pressure contact spring 47 that applies contact pressure of the vacuum valve 44, a drive shaft 48 that drives the vacuum valve 44, and an operation unit 49 that drives the drive shaft 48 with a magnet via the pressure contact spring 47. Configured. In this example, the operation unit 49 is disposed horizontally, but may be disposed anywhere as long as there is a space.
The conductor 51 connected to the vacuum valve 44 is connected to a power source through a hollow portion of the annular current sensor 52.

つまり、電源に導体４３を介して高圧ヒューズ２４の一端が接続され、高圧ヒューズ２４の他端が導体４５を介して真空バルブ４４の一端に接続され、真空バルブ４４の他端が電流センサ５２を通る導体５１を介して電源に接続されている。この電気経路には、破線矢印Ｙ３で示すように図示せぬ電源電圧からの電流ｉが、高圧ヒューズ２４、真空バルブ４４の順に流れるようになっている。   That is, one end of the high voltage fuse 24 is connected to the power source via the conductor 43, the other end of the high voltage fuse 24 is connected to one end of the vacuum valve 44 via the conductor 45, and the other end of the vacuum valve 44 connects the current sensor 52. It is connected to a power source through a passing conductor 51. A current i from a power supply voltage (not shown) flows through the electric path in the order of the high voltage fuse 24 and the vacuum valve 44 as indicated by a broken line arrow Y3.

このような構成のＶＣＳ４０が高圧コンビネーションスタータ盤１０に収納され、高電圧モータを起動している場合に、上記の電流経路に真空バルブ４４の開閉で対応しきれない大きな短絡電流が流れ、これによって高圧ヒューズ２４が切れたとする。この際、電流経路が遮断されるので高電圧モータは保護されるが、高圧ヒューズ２４を新しいものと交換しなければならない。   When the VCS 40 having such a configuration is housed in the high-voltage combination starter panel 10 and the high-voltage motor is started, a large short-circuit current that cannot be handled by opening and closing the vacuum valve 44 flows in the current path. Assume that the high-voltage fuse 24 is blown. At this time, since the current path is interrupted, the high voltage motor is protected, but the high voltage fuse 24 must be replaced with a new one.

この場合、作業者は、ＶＣＳ４０を図２に示したインターロックレバー２７でインターロックを解除した後、把手２６を持って前方の試験／断路位置Ｐ１まで引き出す。そして、保護カバー４２を開けて、切れた高圧ヒューズ２４を取り外し、新しい高圧ヒューズ２４を装着する。そして、把手２６を持ち盤１０内の元の位置に戻す。   In this case, the operator releases the interlock of the VCS 40 with the interlock lever 27 shown in FIG. 2, and then pulls the VCS 40 to the front test / disconnection position P <b> 1 with the handle 26. Then, the protective cover 42 is opened, the broken high voltage fuse 24 is removed, and a new high voltage fuse 24 is installed. Then, the handle 26 is returned to the original position in the holding board 10.

以上説明したように本実施の形態の高圧真空電磁接触器４０によれば、高圧ヒューズ２４をＶＣＳ４０における盤１０の正面側位置に着脱自在に配置し、ＶＣＳ４０を盤１０から試験／断路位置Ｐ１に引き出し、この位置で高圧ヒューズ２４を交換できるようにしたので、従来に比べ容易に交換することができる。
従来は、リフタ３０にＶＣＳ１２を載置して引き出し、ＶＣＳ１２を床まで下ろしてから高圧ヒューズ２４を交換し、交換後は逆の手順でＶＣＳ１２を盤１０に収納しなければならなかったので、リフタ３０を用いた手間が掛かる手順を必要としていた。 As described above, according to the high-pressure vacuum electromagnetic contactor 40 of the present embodiment, the high-voltage fuse 24 is detachably disposed at the front side position of the panel 10 in the VCS 40, and the VCS 40 is moved from the panel 10 to the test / disconnection position P1. Since the high-voltage fuse 24 can be exchanged at this position, it can be easily replaced as compared with the conventional case.
Conventionally, the VCS 12 has been placed on the lifter 30 and pulled out, the VCS 12 has been lowered to the floor, and then the high voltage fuse 24 has been replaced. After the replacement, the VCS 12 has to be stored in the panel 10 in the reverse order. The procedure which requires time and effort using 30 was required.
