器が健全な場合であるが、主電動機が閃絡接地事
故を起こした場合等の動作について説明する。 At startup, the traction motor is connected in series with the starting resistor, and all resistor short-circuit contactors are in an open state. The starting resistance is successively short-circuited by the resistance shorting contactors R1 to R8 as the electric car accelerates due to the action of the current limiting relay CL that controls the starting current, and the starting resistance is shorted by the closing of the resistance shorting contactor R8. are all short-circuited and enter a state of characteristic acceleration. The above control is performed when the electrical equipment is healthy, but the operation when the main motor causes a flash fault grounding accident will be explained.

路接点Ｌ−２が開路し、過大電流をしや断する。 When the main motor flashes to ground, the overhead line is directly grounded, and the overcurrent relay coil
Excessive current flows. This overcurrent activates the overcurrent relay, and its auxiliary contact OCR-2
The coil L-1 of the current relay is demagnetized and the main circuit contact L-2 of the current interrupter opens, thereby interrupting the excessive current.

電器が動作した事を表示する。 Once activated, the overcurrent relay mechanically remembers the operating state and resets the OCR-3 reset coil.
It will not be reset unless it is energized. When the overcurrent relay operates, the auxiliary contact OCR-4 lights up the indicator light OCLP on the driver's cab, indicating that the overcurrent relay has operated.

機制御装置のごく一般的な制御方法である。 The overcurrent relay is reset by returning the master controller MC to the OFF position and then pressing the reset switch RSW. Pressing the reset switch resets the overcurrent relay coil OCR.
-3 is energized, the overcurrent relay is reset, and the auxiliary contact OCR-2 is closed to prepare for the next operation.
In addition, due to the opening of OCR-4, the driver's cab indicator light OCLP
goes out. In addition, the OCR reset coil OCR-
3 is usually made with a short-time rating, and OCR
The auxiliary contact OCR-5 is inserted to protect the coil when the reset signal is continuously issued for some reason. The above control is a very common control method for electric vehicle motor control devices.

とすることも出来ない。 Figure 3 shows a cam diagram of an overcurrent relay. The driver's cab reset switch RSW is normally
It is configured with a spring return type to keep the contact open. The driver can operate by pressing the reset switch RSW a little and then releasing it, or by turning on the overcurrent indicator OCLP.
It is easy to perform operations such as letting go of your hand as soon as the light goes out. Upon such operation of the reset switch RSW, the overcurrent relay may stall. That is, the reset signal is not completely generated, and the a contact OCR-4 is open, but the b contact OCR-2 also remains open. The overcurrent indicator light OCLP in the driver's cab is off, but even if the main controller MC is operated, the current breaker L does not operate and the electric car cannot be started. Also, reset switch
Even if the RSW is operated again, the overcurrent relay cannot be completely reset because the OCR-5 is open.
