What is the cause of energy storage switch trip

Jan 07, 2022

Closing spring and tripping spring are independent, energy storage mechanism generally only to closing spring energy storage, and tripping spring is generally relying on circuit breaker closing action energy storage in series in the closing loop with switch energy storage contact, that is to say, the switch can not be closed without energy storage. But there is no series switch and no energy storage contact in the opening circuit. So even if the switch does not store energy, you can also jump off. (Note: the switch does not store energy here refers to the closing spring does not store energy, and the release spring does not store energy is no contact out).


When the circuit breaker is disconnected, the opening spring has not stored energy, and the closing spring has stored energy. When closing, the closing spring releases energy, and the closing spring stores energy at the same time. To make sure the switch jumps when it closes. When the closing spring releases energy (the switch is just closed), the motor begins to store energy for the closing spring, which takes about ten seconds. At this time, it is considered as a failure, because the opening spring has stored energy, so it can jump off. This also shows that when the hand is in trouble, the switch can immediately jump off, but this kind of jump can not immediately again overlap (need to be different from the reclosing), because the closing has not stored energy, to wait for the end of energy storage to send power again. And if the switch is closed, at this time the switch closing spring and break spring have energy storage. When there is a fault, the brake spring releases energy to brake. After a second or so, the closing spring releases energy to close. And at the end of the closing, the opening spring has ended the energy storage, but the closing spring has not been good energy storage. If the switch is closed at fault, the switch can be jumped immediately because the release spring ends up storing energy. However, after jumping off, it cannot be closed again immediately, and it needs to wait until the energy storage of the closing spring is finished (generally, the switch takes 30 seconds, but in our actual situation, it can be tried again after the accident is handled).


Generally should be closed (at the same time for the spring storage), after closing the closing spring energy storage, ready for the next closing;

If there is no energy storage after tripping, then reclosing cannot be achieved;

It is recommended to check the integrity of the energy storage loop as soon as possible.
