    Tips: Vacuum ac contactor troubleshooting

    Whether the vacuum ac contactor is faulty or not can be judged according to whether it can be closed and opened accurately and reliably and kept in the closing and opening positions. The failure of the main circuit can be found and eliminated from the routine inspection and maintenance of the vacuum ac contactor. The common failure analysis of vacuum ac contactor is as follows:

    • Inability to store energy: Inability to store energy is one of the common failures of vacuum contactors, especially the energy storage mechanism driven by ratchets and pawls has a higher probability of failure. The energy storage mechanism to complete the energy storage action mainly depends on the three links of the energy storage motor, the drive mechanism, and the positioning parts. Grasping these three links firmly, it is easy to find out the cause of the ac vacuum contactor failure.
    • No closing action: The fault here is mainly related to whether the closing electromagnet is closed, whether the energy storage is in place, and whether the positioning member is operating normally.
    • The ac vacuum contactor has a closing action but fails to close. When analyzing this type of failure, you should first analyze the lock, and then analyze whether it is related to the energy storage part.
    • The ac vacuum contactor does not open: It should be emphasized here that when the vacuum ac contactor refuses to move or closes, before analyzing and repairing the main body of the contactor, it is necessary to fully judge whether the reason is in the control and secondary components such as auxiliary switches, terminal blocks, etc., and then analyze and diagnose the contactor.
