SS3型4000系高低压试验（SS3 type 4000 high voltage test）

SS3型4000系高低压试验（SS3 type 4000 high voltage test） The key test Closed DSK without interlocking movement sound If the forerunners are closed FGJ or YGJ, it can be confirmed whether FGZJ or FGZJ can have the power of self-hold, unable to hold to 1ZK jump or 1 (2) DSK contact, and the test can be distinguished between 1ZK and 1 (2) DSK. If YGZJ or FGZJ can self sustaining, artificial pick up pressure BHF core (or confirm that the BHF core sucked down), if the door interlock action, as theres a bug in the BHF circuit, i.e. the kyk, kyk 1 or 2 LK contact undesirable or travel switch is not closed in place or BHF itself is bad, if press the door interlock when BHF is not action, failure is the wind road. If the wind road is open, the wind pressure of 102 air cylinder is confirmed. If the wind is open, 97 diaphragm plate valves are open, and the door interlocking action is closed or 108 inversion for 131 or 114 plug doors. If the door interlock does not move, close one (2) ZKZ2, the main circuit breaker action, then the 100 pressure regulating valve is not good. If there is no wind in the 102 air cylinder, a small air pump is played, and the door interlock action is 131. No door interlocking movement sound, but the main circuit ground signal light First use the reversing handle 1 (2) SKX or artificially reverser to Ⅰ side forward or backward, let 323 lines have electricity. If 1XC ~ 6XC can be electrocutively, then 2KYK or 1KYK will be used in the library. 3. When giving the key, there is a door interlocking movement sound, repeatedly breaking the DSK, the door interlocking movement sound from strong to weak, until silent There is a wind position in the plug gate; Judgment method: the main circuit breaker is broken without the jitter of the main circuit, and the main circuit breaker can not be heard in the wind (low voltage test). After the DSK, the door interlock action, the signal indicator is not displayed The switch test, if normal, is between 245 ~ 550 lines and 1 (2) D
