【考案の詳細な説明】
本考案は、車両用過負荷防止延長給電回路に関
するものである。[Detailed Description of the Invention] The present invention relates to an overload prevention extended power supply circuit for a vehicle.
車両の電動発電機等電源装置に故障が生じた場
合には、例えば天井蛍光灯等の負荷の電源が無く
なるため隣接車よりの延長給電操作をする必要が
生じてくる。 When a failure occurs in a power supply device such as a motor generator of a vehicle, the power supply for a load such as a ceiling fluorescent light is lost, and it becomes necessary to perform an extended power supply operation from an adjacent vehicle.
従来、このような延長給電方法の一つとして、
故障車１個所からだけの切換スイツチを操作する
という方法があるが、この方法によると、例えば
編成車両内に電動発電機が３個以上ありその内２
個以上が故障した場合には、１個の電動発電機で
２個以上の電動発電機搭載車分の負荷をも負担さ
せる（合計３ユニツト分を負担させる）回路もで
き、この場合には電動発電機が過負荷となるとい
う欠点があつた。 Conventionally, as one of such extended power supply methods,
There is a method of operating the changeover switch from only one broken car, but according to this method, for example, if there are three or more motor generators in the train set and two of them are
In the event that one or more motor generators fail, a circuit is created in which one motor generator bears the load of a vehicle equipped with two or more motor generators (total load for 3 units). The drawback was that the generator was overloaded.
本考案は、このような過負荷を防止することを
目的としたものである。 The present invention aims to prevent such overload.
以下、本考案の一実施例を図によつて説明す
る。図は、電動発電機を有する同一型式の車両
（３両）を並べて示した簡略電気回路図である。

器、８は制御回路電源線である。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings. The figure is a simplified electrical circuit diagram showing three vehicles of the same type having motor generators arranged side by side.
1 is a molded circuit breaker for circuit protection, 2 is an extended power supply selection switch, 3 is an extended power supply contactor, 3a is its A contact, 4 is an extended power supply limiting relay which is the main point of the present invention, 4a is its B contact , 5 is a load, 6 is a motor generator, 7 is an electrical coupler for crossing electric wires between vehicles, and 8 is a control circuit power line.
今、２号車の電動発電機６が故障し１号車より
受電する場合を考える。故障車である２号車の延
長給電選択スイツチ２をｉ側に倒す（健全車はＮ
位置のまま）と、制御回路電源線８から配線用遮
断器１、延長給電選択スイツチ２を通り延長給電
制限継電器４が励磁されると共に、電気連結器７
を介して１号車の延長給電制限継車器４のｂ接点
４ａを通り延長給電接触器３が励磁されるので、
その接点３ａは閉路となり、１号車の電動発電機
６の出力が電気連結器７を通つて２号車に延長給
電される。 Now, let us consider a case where the motor generator 6 of car No. 2 breaks down and receives power from car No. 1. Turn the extended power supply selection switch 2 of car No. 2, which is a broken car, to the i side (if the car is healthy, turn it to N).
position), the extended power supply limiting relay 4 is energized from the control circuit power line 8 through the molded circuit breaker 1 and the extended power supply selection switch 2, and the electrical coupler 7 is energized.
The extended power supply contactor 3 is energized through the b contact 4a of the extended power supply limiting relay 4 of the first car.
The contact point 3a becomes a closed circuit, and the output of the motor generator 6 of the first car is extended to be supplied with power to the second car through the electrical coupler 7.
この状態では、３号車の延長給電選択スイツチ
２をｉ側に倒した場合でも、２号車の延長給電制
限継電器４が励磁されているためそのｂ接点４ａ
は開路となつており、２号車の延長給電接触器３
は励磁されないのでそのａ接点３ａは開路のまま
である。したがつて、１号車に電動発電機で３号
車の車両負荷を負担することにはならず、すなわ
ち、１個の電動発電機で３ユニツトの車両負荷を
負担することはできないことになる。このよう
に、本考案は例えば電動発電機に対する過負荷防
止を、延長給電操作と同時にしかも自動的に行な
うことができるものであり、他の電源装置の場合
でも同様に過負荷防止ができるものである。 In this state, even if the extended power supply selection switch 2 of the 3rd car is turned to the i side, the extended power supply limiting relay 4 of the 2nd car is energized, so its b contact 4a
is open circuit, and extended power supply contactor 3 of car 2
is not excited, so its a contact 3a remains open. Therefore, the motor-generator in car No. 1 does not bear the vehicle load of car No. 3, that is, it is not possible to bear the vehicle load of three units with one motor-generator. In this way, the present invention can automatically prevent overloads on motor generators, for example, at the same time as extended power supply operations, and can similarly prevent overloads on other power supplies. be.
以上述べたように、本考案によれば延長給電回
路において電源装置の過負荷を防止することがで
きる効果がある。 As described above, the present invention has the effect of preventing overload of the power supply device in the extended power supply circuit.
