　しかし、このような電力システムは、電力連携線に落雷があると、その電力引き込み線に接続された装置が、落雷に伴う高電圧や高電流により破壊されるおそれがある。また、雷雲がかなり近付いてから突然ブレーカーなどで蓄電池を引込み線から切り離すと、蓄電池の容量が少ない場合は、雷雲が遠ざかる前に電力不足となり、停電してしまう。また、単に引き込み線を切り離しただけでは、近傍に落雷した場合の電磁波による誘起電圧でリレー接点間の絶縁を破壊し、家庭内機器に被害を及ぼしてしまうこともあり、接点開閉距離が大きいリレーを用いると、装置が大型化してしまう。 However, in such a power system, if there is a lightning strike on the power connection line, the device connected to the power lead-in line may be destroyed by the high voltage or high current accompanying the lightning strike.

　［１．１．経緯］
　本開示の実施の形態について詳細に説明する前に、本開示の実施の形態に至った経緯を説明する。 <1. Embodiment of the present disclosure>
[1.1. History]
Before describing the embodiment of the present disclosure in detail, the background to the embodiment of the present disclosure will be described.
　上述したように、蓄電池を備えることで、入力電源からの電力が途絶えても、接続されている機器に対して、停電することなく所定の時間電力を蓄電池から供給し続けることができる無停電電源装置の存在が知られている。このような電源装置を需要家単位に拡大して、停電等の電力供給の異常発生時に電力を需要家に供給する電力システムが提案されている。 As described above, an uninterruptible power supply that can continue to supply power from a storage battery for a predetermined time without power failure to connected devices even if the power from the input power supply is interrupted by providing the storage battery The existence of the device is known. There has been proposed a power system that expands such a power supply device for each customer and supplies power to the customer when a power supply abnormality such as a power failure occurs.
　しかし、このような電力システムは、電力連携線に落雷があると、その電力引き込み線に接続された装置が、落雷に伴う高電圧や高電流により破壊されるおそれがある。また、雷雲がかなり近付いてから突然ブレーカーなどで蓄電池を引込み線から切り離すと、蓄電池の容量が少ない場合は、雷雲が遠ざかる前に電力不足となり、停電してしまう。また、単に引き込み線を切り離しただけでは、近傍に落雷した場合の電磁波による誘起電圧でリレー接点間の絶縁を破壊し、家庭内機器に被害を及ぼしてしまうこともあり、接点開閉距離が大きいリレーを用いると、装置が大型化してしまう。 However, in such a power system, if there is a lightning strike on the power connection line, the device connected to the power lead-in line may be destroyed by the high voltage or high current accompanying the lightning strike. Also, if the storage battery is suddenly disconnected from the lead-in line with a breaker or the like after the thundercloud has approached considerably, if the capacity of the storage battery is small, power will be insufficient before the thundercloud moves away, causing a power failure. In addition, if the lead-in wire is simply disconnected, the insulation between the relay contacts may be damaged by the induced voltage caused by electromagnetic waves when a lightning strikes nearby, causing damage to household equipment. If is used, the apparatus becomes large.
　そこで本件開示者は、上述した点に鑑み、装置の大型化を避けつつ、雷雲の接近状況に応じて蓄電池へ供給する電力の電力源を柔軟に切り替えることが可能な技術について鋭意検討を行った。その結果、本件開示者は、以下で説明するように、装置の大型化を避けつつ、雷雲の接近状況に応じて蓄電池へ供給する電力の電力源を柔軟に切り替えることが可能な技術を考案するに至った。 Therefore, in view of the above-described points, the present disclosure has intensively studied a technology that can flexibly switch the power source of the power supplied to the storage battery according to the approach situation of thunderclouds while avoiding the enlargement of the device. . As a result, as will be described below, the present disclosure devised a technology that can flexibly switch the power source of the power supplied to the storage battery according to the approaching situation of thunderclouds while avoiding the enlargement of the device. It came to.
　［１．２．構成例］
　続いて、本開示の実施の形態に係る電力システムの構成例を説明する。図１は、本開示の実施の形態に係る電力システムの構成例を示す説明図である。以下、図１を用いて本開示の実施の形態に係る電力システムの構成例について説明する。 [1.2. Configuration example]
Subsequently, a configuration example of the power system according to the embodiment of the present disclosure will be described. FIG. 1 is an explanatory diagram illustrating a configuration example of a power system according to an embodiment of the present disclosure. Hereinafter, a configuration example of the power system according to the embodiment of the present disclosure will be described using FIG. 1.
　図１に示したように、本開示の実施の形態に係る電力システムは、蓄電装置１００と、インバータ２００と、雷検出アンテナ３００と、雷検出器３１０と、太陽光パネル４００と、を含んで構成される。 As shown in FIG. 1, the power system according to the embodiment of the present disclosure includes a power storage device 100, an inverter 200, a lightning detection antenna 300, a lightning detector 310, and a solar panel 400. Composed.
　蓄電装置１００は、内部に蓄電池を有し、蓄電池への充電を実行するとともに、蓄電池に蓄えた電力を家庭内の電化製品に供給することを目的とした装置である。蓄電装置１００は、蓄電制御装置１１０と、蓄電池１２０と、パワーコンディショナ（ＰＷＣ）１３０と、リレー１４０、１５０と、を含んで構成される。 The power storage device 100 is a device that has a storage battery inside and performs charging of the storage battery, and also supplies power stored in the storage battery to household appliances. The power storage device 100 includes a power storage control device 110, a storage battery 120, a power conditioner (PWC) 130, and relays 140 and 150.
　蓄電制御装置１１０は、太陽光パネル４００や、商用電源等の外部電力源で発電された電力を蓄電池１２０へ蓄電するための制御を行う。蓄電制御装置１１０は、蓄電池１２０の蓄電量が一定以下になると、外部電力源からの電力も用いて蓄電池１２０へ充電することができる。なお、外部電力源は交流電源であっても良く、直流電源であっても良い。 The power storage control device 110 performs control for storing the power generated by the solar panel 400 or an external power source such as a commercial power source in the storage battery 120. The power storage control device 110 can charge the storage battery 120 using the power from the external power source when the storage amount of the storage battery 120 falls below a certain level. The external power source may be an AC power supply or a DC power supply.
　また蓄電制御装置１１０は、雷雲の接近に応じて蓄電池１２０への充電に用いる電力を切り替える装置である。蓄電制御装置１１０は、蓄電池１２０から蓄電量（ＳｏＣ；Ｓｔａｔｅ　ｏｆ　Ｃｈａｒｇｅ）の情報や、雷検出器３１０から取得した雷までの距離及びエネルギー情報を取得し、その取得した情報に基づき、リレー１４０、１５０の動作を制御する。 Further, the power storage control device 110 is a device that switches the power used for charging the storage battery 120 according to the approach of thunderclouds. The power storage control device 110 acquires information on a storage amount (SoC) from the storage battery 120, distance to the lightning acquired from the lightning detector 310, and energy information, and based on the acquired information, the relay 140, 150 operations are controlled.
　蓄電制御装置１１０は、雷検出器３１０から取得した情報を用いることで、雷が近隣の鉄塔などに直撃して停電が発生する前に、蓄電池１２０に十分蓄電することができ、雷雲が近づいたときは外部電力源や太陽光パネル４００からの電力引き込み線をリレー１４０、１５０で切り離すことができる。 By using the information acquired from the lightning detector 310, the power storage control device 110 can sufficiently store power in the storage battery 120 before lightning strikes a nearby steel tower and a power failure occurs, and a thundercloud approaches. Sometimes, the external power source or the power lead-in line from the solar panel 400 can be disconnected by the relays 140 and 150.
　蓄電制御装置１１０は、雷が近付いている際にはあらかじめ外部電力源や太陽光パネル４００からの電力引き込み線をリレー１４０、１５０で切り離すことで、雷による電流サージをパワーコンディショナ１３０や家庭内の電化製品に流さないようにすることができる。従って、蓄電制御装置１１０は、電化製品を雷サージによる故障から守りながら、雷雲の通過中は蓄電池１２０に蓄電された電力を家庭内の電化製品に供給することができ、家庭における平常通りの生活を可能としている。 When lightning is approaching, the power storage control device 110 disconnects the power supply line from the external power source or the solar panel 400 with the relays 140 and 150 in advance, thereby preventing the current surge caused by the lightning from occurring in the power conditioner 130 or the home. It can be prevented from flowing into the appliances. Therefore, the power storage control device 110 can supply the power stored in the storage battery 120 to the home appliance while the thundercloud passes while protecting the home appliance from a lightning surge failure. Is possible.
　蓄電池１２０は、充放電が可能な二次電池であり、例えば商用電源からの電力供給が途絶しても、テレビや冷蔵庫などの家庭内の電化製品へ所定の時間電力を供給できるだけの容量を有する。蓄電池１２０は、蓄電量（ＳｏＣ）の情報を蓄電制御装置１１０へ提供することが出来る機能を有する。 The storage battery 120 is a secondary battery that can be charged and discharged, and has a capacity that can supply power to a home appliance such as a television or a refrigerator for a predetermined time even when power supply from a commercial power supply is interrupted, for example. . The storage battery 120 has a function of providing information on the storage amount (SoC) to the storage control device 110.
　パワーコンディショナ１３０は、太陽光パネル４００により発電された電力、または外部電力源１０から供給される電力を、蓄電池１２０への蓄電に適した電力に変換する機能を有する。 The power conditioner 130 has a function of converting the power generated by the solar panel 400 or the power supplied from the external power source 10 into power suitable for power storage in the storage battery 120.
　リレー１４０は、太陽光パネル４００とパワーコンディショナ１３０との間に設けられ、太陽光パネル４００で発電される電力の蓄電池１２０への供給と遮断とを切り替える。リレー１５０は、外部電力源１０とパワーコンディショナ１３０との間に設けられ、外部電力源１０から供給される電力の蓄電池１２０への供給と遮断とを切り替える。 The relay 140 is provided between the solar panel 400 and the power conditioner 130, and switches between supplying and shutting off the electric power generated by the solar panel 400 to the storage battery 120. The relay 150 is provided between the external power source 10 and the power conditioner 130, and switches between supply and interruption of the power supplied from the external power source 10 to the storage battery 120.
　図２は、リレー１４０の構成例を示す説明図である。リレー１４０は、図２に示したように、ノーマリークローズ（ＮＣ）、ノーマリーオープン（ＮＯ）、コモン（Ｃ）の３端子を有する。ノーマリークローズの端子は太陽光パネル４００と接続されており、ノーマリーオープンの端子は接地されている。リレー１５０についても、リレー１４０と同等の構成を有する。 FIG. 2 is an explanatory diagram showing a configuration example of the relay 140. As shown in FIG. 2, the relay 140 has three terminals of normally closed (NC), normally open (NO), and common (C). The normally closed terminal is connected to the solar panel 400, and the normally open terminal is grounded. The relay 150 also has a configuration equivalent to that of the relay 140.
　このように、リレー１４０、１５０は片側が接地されていることで、仮に近傍に落雷し、落雷に伴う電磁波で誘起する電圧により接点が絶縁破壊した場合でも、リレー１４０、１５０に接続されたパワーコンディショナ１３０の破壊を防ぐことができる。 As described above, the relays 140 and 150 are grounded on one side, so that even if a lightning strikes in the vicinity and the contact breaks down due to a voltage induced by electromagnetic waves accompanying the lightning strike, the power connected to the relays 140 and 150 It is possible to prevent the conditioner 130 from being destroyed.
　インバータ２００は、蓄電装置１００から家庭内の電化製品へ電力を供給する際に、電化製品に適した電力に変換する装置である。電化製品が交流で動作するものであれば、インバータ２００は、電力を直流から交流に変換する。また電化製品が直流で動作するものであれば、インバータは電圧の調整を行う。 The inverter 200 is a device that converts electric power suitable for an electric appliance when supplying electric power from the power storage device 100 to the electric appliance in the home. If the electrical appliance operates with alternating current, inverter 200 converts power from direct current to alternating current. In addition, if the electric appliance operates on DC, the inverter adjusts the voltage.
　雷検出アンテナ３００は、落雷の発生を検出するアンテナである。雷検出アンテナ３００は、落雷の発生により電波を受信すると、その電波を雷検出器３１０に出力する。雷検出器３１０は、雷検出アンテナ３００から送られる電波から、雷までの距離と、雷によるエネルギーと、を算出する。雷検出器３１０は、算出した雷までの距離及び雷によるエネルギーの情報を蓄電装置１００へ提供する。 The lightning detection antenna 300 is an antenna that detects the occurrence of a lightning strike. When the lightning detection antenna 300 receives a radio wave due to a lightning strike, the lightning detection antenna 300 outputs the radio wave to the lightning detector 310. The lightning detector 310 calculates the distance to the lightning and the energy of the lightning from the radio wave transmitted from the lightning detection antenna 300. The lightning detector 310 provides information on the calculated distance to the lightning and energy of the lightning to the power storage device 100.
　続いて蓄電装置１００に含まれる蓄電制御装置１１０の機能構成例について説明する。図３は、本開示の実施の形態に係る蓄電制御装置１１０の機能構成例を示す説明図である。 Subsequently, a functional configuration example of the power storage control device 110 included in the power storage device 100 will be described. FIG. 3 is an explanatory diagram illustrating a functional configuration example of the power storage control device 110 according to the embodiment of the present disclosure.
　図３に示したように、本開示の実施の形態に係る蓄電制御装置１１０は、距離情報取得部１１１と、蓄電情報取得部１１２と、充電元切替部１１３と、を含んで構成される。 As shown in FIG. 3, the power storage control device 110 according to the embodiment of the present disclosure includes a distance information acquisition unit 111, a power storage information acquisition unit 112, and a charging source switching unit 113.
　距離情報取得部１１１は、雷発生時に、雷までの距離及び雷によるエネルギーの情報を雷検出器３１０から取得する。蓄電情報取得部１１２は、蓄電池１２０の蓄電量（ＳｏＣ）の情報を蓄電池１２０から取得する。 The distance information acquisition unit 111 acquires information about the distance to the lightning and the energy of the lightning from the lightning detector 310 when a lightning occurs. The storage information acquisition unit 112 acquires information on the storage amount (SoC) of the storage battery 120 from the storage battery 120.
　充電元切替部１１３は、距離情報取得部１１１及び蓄電情報取得部１１２が取得した情報に基づいて、リレー１４０、１５０の動作を制御する。充電元切替部１１３は、リレー１４０、１５０の動作を制御することで、蓄電池１２０へ供給する電力を切り替える。充電元切替部１１３によるリレー１４０、１５０の動作の制御例については後に詳述する。 The charging source switching unit 113 controls the operation of the relays 140 and 150 based on the information acquired by the distance information acquisition unit 111 and the power storage information acquisition unit 112. The charging source switching unit 113 switches the power supplied to the storage battery 120 by controlling the operations of the relays 140 and 150. An example of controlling the operation of the relays 140 and 150 by the charging source switching unit 113 will be described in detail later.
　以上、図３を用いて本開示の実施の形態に係る電力システムの構成例について説明した。続いて、本開示の実施の形態に係る蓄電装置１００の動作例について説明する。 The configuration example of the power system according to the embodiment of the present disclosure has been described above with reference to FIG. Subsequently, an operation example of the power storage device 100 according to the embodiment of the present disclosure will be described.
　［１．３．動作例］
　図４は、本開示の実施の形態に係る蓄電装置１００の動作例を示す流れ図である。以下、図４を用いて本開示の実施の形態に係る蓄電装置１００の動作例について説明する。 [1.3. Example of operation]
FIG. 4 is a flowchart illustrating an operation example of the power storage device 100 according to the embodiment of the present disclosure. Hereinafter, an operation example of the power storage device 100 according to the embodiment of the present disclosure will be described with reference to FIG.
　雷が発生したことが雷検出アンテナ３００により検出されると、蓄電制御装置１１０が、雷検出器３１０から、雷までの距離および雷によるエネルギー情報を取得する（ステップＳ１０１）。雷までの距離および雷によるエネルギー情報は、例えば距離情報取得部１１１が取得する。また蓄電制御装置１１０は、蓄電池１２０の蓄電量（ＳｏＣ）の情報を取得する（ステップＳ１０２）。蓄電池１２０の蓄電量の情報は、例えば蓄電情報取得部１１２が取得する。 When the occurrence of lightning is detected by the lightning detection antenna 300, the power storage control device 110 obtains the distance to the lightning and the energy information by the lightning from the lightning detector 310 (step S101). For example, the distance information acquisition unit 111 acquires the distance to lightning and the energy information by the lightning. In addition, the power storage control device 110 acquires information on the storage amount (SoC) of the storage battery 120 (step S102). The information on the amount of power stored in the storage battery 120 is acquired by, for example, the power storage information acquisition unit 112.
　そして蓄電制御装置１１０は、上記ステップＳ１０１、Ｓ１０２で取得した情報に基づいて、蓄電池１２０への充電に用いる電力を切り替える（ステップＳ１０３）。蓄電池１２０への充電に用いる電力の切り替えは、例えば充電元切替部１１３が実行する。 And the electrical storage control apparatus 110 switches the electric power used for charge to the storage battery 120 based on the information acquired by said step S101, S102 (step S103). Switching of the electric power used for charging the storage battery 120 is executed by, for example, the charging source switching unit 113.
　具体例を挙げて蓄電制御装置１１０による蓄電池１２０への充電に用いる電力の切り替え動作を説明する。図５は、蓄電制御装置１１０による蓄電池１２０への充電に用いる電力の切り替え動作を説明する説明図である。 A switching operation of power used for charging the storage battery 120 by the power storage control device 110 will be described with a specific example. FIG. 5 is an explanatory diagram for explaining a switching operation of power used for charging the storage battery 120 by the power storage control device 110.
　時刻ｔ１より前の時点では、雷検出アンテナ３００から雷雲までの距離が充分離れているため、蓄電制御装置１１０は、リレー１４０、１５０のいずれもオン（ＮＣに接続されている）状態にする。この時点では、蓄電制御装置１１０は、太陽光パネル４００で発電された電力を優先的に蓄電池１２０への充電に用いるモード（ＰＶ優先充電モード）で蓄電池１２０への充電を行っている。 Since the distance from the lightning detection antenna 300 to the thundercloud is sufficiently far before the time t1, the power storage control device 110 turns on both the relays 140 and 150 (connected to the NC). At this time, the power storage control device 110 is charging the storage battery 120 in a mode (PV priority charging mode) in which the power generated by the solar panel 400 is preferentially used for charging the storage battery 120.
　時刻ｔ１の時点で、雷検出アンテナ３００から雷雲までの距離が所定の第１の距離Ｄ１以下になったことが検出されると、蓄電制御装置１１０は、外部電力源１０で発電された電力を優先的に蓄電池１２０への充電に用いるモード（外部電力優先充電モード）に切り替える。この外部電力優先充電モードは、蓄電池１２０のＳｏＣが１００％に近い状態になるまで、外部電力源１０からの電力を用いて積極的に蓄電池１２０へ充電することを目的としたらモードである。 When it is detected that the distance from the lightning detection antenna 300 to the thundercloud is equal to or less than the predetermined first distance D1 at time t1, the power storage control device 110 uses the power generated by the external power source 10 The mode is switched to a mode (external power priority charging mode) used for charging the storage battery 120 with priority. This external power priority charging mode is a mode that aims at positively charging the storage battery 120 using the power from the external power source 10 until the SoC of the storage battery 120 is close to 100%.
　さらに、時刻ｔ２の時点で、雷検出アンテナ３００から雷雲までの距離が所定の第１の距離Ｄ１より短い第２の距離Ｄ２以下になったことが検出されると、蓄電制御装置１１０は、リレー１５０をオフ（ＮＯに接続されている）状態にする。これにより、蓄電装置１００は外部電力源１０から切り離される。 Furthermore, at time t2, when it is detected that the distance from the lightning detection antenna 300 to the thundercloud is equal to or less than the second distance D2 shorter than the predetermined first distance D1, the power storage control device 110 150 is turned off (connected to NO). Thereby, power storage device 100 is disconnected from external power source 10.
　さらに、時刻ｔ３の時点で、雷検出アンテナ３００から雷雲までの距離が所定の第２の距離Ｄ２より短い第３の距離Ｄ３以下になったことが検出されると、蓄電制御装置１１０は、リレー１４０もオフ（ＮＯに接続されている）状態にする。これにより、蓄電装置１００は外部電力源１０だけでなく太陽光パネル４００からも切り離される。従って、時刻ｔ３の時点になると、家庭内の電化製品は蓄電池１２０からの電力のみによって動作する。 Further, at time t3, when it is detected that the distance from the lightning detection antenna 300 to the thundercloud is equal to or less than the third distance D3 shorter than the predetermined second distance D2, the power storage control device 110 140 is also turned off (connected to NO). Thereby, power storage device 100 is disconnected not only from external power source 10 but also from solar panel 400. Therefore, at time t3, the household appliances operate only with the electric power from the storage battery 120.
　その後、雷雲が遠ざかっていき、時刻ｔ４の時点で、雷検出アンテナ３００から雷雲までの距離が第３の距離Ｄ３より長くなったことが検出されると、蓄電制御装置１１０は、リレー１４０をオン状態にする。また時刻ｔ５の時点で、雷検出アンテナ３００から雷雲までの距離が第２の距離Ｄ２より長くなったことが検出されると、蓄電制御装置１１０は、リレー１５０をオン状態にする。 After that, when the thundercloud moves away and at time t4, it is detected that the distance from the thunder detection antenna 300 to the thundercloud is longer than the third distance D3, the power storage control device 110 turns on the relay 140. Put it in a state. Further, at time t5, when it is detected that the distance from the lightning detection antenna 300 to the thundercloud is longer than the second distance D2, the power storage control device 110 turns on the relay 150.
　そして、時刻ｔ６の時点で、雷検出アンテナ３００から雷雲までの距離が第１の距離Ｄ１より長くなったことが検出されると、蓄電制御装置１１０は、外部電力優先充電モードからＰＶ優先充電モードに切り替える。 When it is detected at time t6 that the distance from the lightning detection antenna 300 to the thundercloud is longer than the first distance D1, the power storage control device 110 changes from the external power priority charging mode to the PV priority charging mode. Switch to.
　なお、時刻ｔ５の時点で、蓄電池１２０のＳｏＣが所定値以上であれば、蓄電制御装置１１０は、この時点で外部電力優先充電モードからＰＶ優先充電モードに切り替えてもよい。 If the SoC of the storage battery 120 is greater than or equal to a predetermined value at the time t5, the power storage control device 110 may switch from the external power priority charging mode to the PV priority charging mode at this time.
　本開示の実施の形態に係る蓄電装置１００は、このような動作を実行することで、雷雲の近接状況に応じて蓄電池１２０を安全に電力引き込み線から切り離したり、電力引き込み線に接続したりすることが出来る。蓄電池１２０を電力線から切り離すための構成はリレー１４０、１５０であり、大型のリレーを用いる必要が無い。従って、本開示の実施の形態に係る蓄電装置１００は、装置の大型化を回避しながらも、雷雲の近接状況に応じて蓄電池１２０を安全に電力引き込み線から切り離したり、電力引き込み線に接続したりすることが出来る。 The power storage device 100 according to the embodiment of the present disclosure performs such an operation, so that the storage battery 120 can be safely disconnected from the power lead-in line or connected to the power lead-in line according to the proximity of thunderclouds. I can do it. The configuration for disconnecting the storage battery 120 from the power line is the relays 140 and 150, and there is no need to use a large relay. Therefore, the power storage device 100 according to the embodiment of the present disclosure can safely disconnect the storage battery 120 from the power lead-in line or connect to the power lead-in line according to the proximity of thunderclouds while avoiding an increase in the size of the device. Can be.
　［１．４．変形例］
　続いて、変形例として、蓄電池に蓄えた電力を売電する場合に上述の技術を適用した例を示す。図６は、本開示の実施の形態に係る電力システムの構成例を示す説明図である。図６に示した電力システムは、蓄電池１２０に蓄えた電力を家庭内の電化製品で使用するだけでなく、他の家庭などへ売電する場合を想定したシステムである。図６に示した構成は、図１に示した構成と比較して、サーキットブレーカ２１０が家庭内に設けられている。 [1.4. Modified example]

FIG. 6 is an explanatory diagram illustrating a configuration example of the power system according to the embodiment of the present disclosure. The power system shown in FIG. 6 is a system that assumes the case where the power stored in the storage battery 120 is used not only by household appliances but also sold to other households. In the configuration shown in FIG. 6, a circuit breaker 210 is provided in the home as compared with the configuration shown in FIG. 1.
　このような電力システムの場合でも、上述の説明と同様に、雷雲の近接状況に応じてリレー１４０、１５０の接続状態を切り替えて、雷雲が近接した場合に蓄電池１２０を安全に電力引き込み線から切り離すことが出来る。 Even in the case of such a power system, similarly to the above description, the connection state of the relays 140 and 150 is switched according to the proximity situation of the thundercloud, and the storage battery 120 is safely disconnected from the power lead-in line when the thundercloud approaches. I can do it.
　＜２，まとめ＞
