Abstract
The invention relates to a CRH380B type motor train unit auxiliary converter extension power supply function test method. The method includes the following steps that: train states are confirmed before auxiliary converter extension power supply; traction converter faults are simulated; and auxiliary inverter extension power supply function testing is performed. According to the invention, the extension function of auxiliary converters of a motor train unit is tested and verified, and therefore, it can be ensured that the motor train unit can continuously output a three-phase alternating-current power source, and safe and reliable operation of the motor train unit can be guaranteed. Compared with the methods in the prior art, and according to the CRH380B type motor train unit auxiliary converter extension power supply function test method, a plug does not need to be disassembled in a plug-in and pull-out manner, and it only needs to operate a monitoring display, and traction converter fault simulation can be performed so that the extension power supply function can be verified. The test method is simple, safe and reliable, and is convenient to operate, and can assist in reducing labor intensity of operators and improving work efficiency by three times.

Property is ensured.
To achieve the above object, the present invention provides a kind of CRH380B types EMUs AuCT extension function of supplying power and surveys
Method for testing, it is characterised in that comprise the following steps：
The first step：Confirm AuCT extension power supply vehicle in front state, it is master control drivers' cab to take head car, and closure is by electricity
Bow, main circuit breaker switch, operation driver monitoring display screen HMI switch to traction interface, confirm all of traction convertor, auxiliary
Current transformer is illustrated as closure state；
Second step：Simulation traction convertor failure, disconnects main circuit breaker switch, the HMI switchings of operation driver monitoring display screen
To traction interface, wherein one traction convertor of traction unit is disconnected by " excision " button, carry out fault simulation；
3rd step：AuCT extends power supply function testing, and closure main circuit breaker switch operates driver monitoring display screen
HMI checks the dispaly state of AuCT, and the extension electrical power contact device of AuCT is connected, by other the one of traction unit
Platform traction convertor is powered for AuCT, and AuCT is shown as closure state, confirms that the extension of AuCT is supplied
Electricity Functional state is normal；
4th step：Reset traction convertor failure, disconnects main circuit breaker switch, the HMI switchings of operation driver monitoring display screen
To traction interface, by " recovery " button reset traction convertor.
