The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch.
Are circuit breaker operating mechanisms stored energy?
The modern circuit breaker operating mechanisms are said to be stored energy mechanisms since there are both opening springs and closing springs. One set of springs usually has tension on it. For this reason, extreme care should be taken when working on or near circuit breaker contacts.
What are modern circuit breaker operating mechanisms?
Modern operating mechanisms are quick to make, quick break. This means that the speed of operation is independent of the speed of the control handle. The modern circuit breaker operating mechanisms are said to be stored energy mechanisms since there are both opening springs and closing springs. One set of springs usually has tension on it.
Why is energy storage spring important in a circuit breaker?
As a powerful component of a circuit breaker, thereliability of energy storage spring plays an important role in the drive and control the operation of a circuit breaker motion process.
