What is the energy storage device of the high voltage cabinet? what's the effect?

The energy storage device of the high-voltage cabinet circuit breaker refers to the circuit breaker of the spring operating mechanism, the mechanical component that drives the contact of the circuit breaker to close quickly. closing action.

Specifically, it includes energy storage spring, energy storage motor, micro reduction box, locking mechanism, energy storage state indicating mechanism, etc.

The spring energy storage operating mechanism has many parts, and it is difficult to achieve high reliability. At present, the more advanced replacement products have permanent magnet operating mechanisms.
