4 FAQs about The spring is used to store energy after the high-voltage cabinet is closed

How does a spring work?

During charging, the spring stores potential energy, which it releases rapidly during discharging. This stored mechanical energy allows consistent operations without relying on an external power source. When the motor rotates, it provides potential energy to store in the spring.

How does spring charging work in a circuit breaker?

When the circuit breaker needs to be opened or closed, the mechanical energy stored in charged springs is released using a release mechanism. Spring charging is essential since it can either open or close the circuit by moving the contacts apart.

How does a tripping spring work?

Part of this energy charges the tripping spring. During the closing operation, the tripping spring deforms and stores energy. That means the tripping (opening) spring becomes charged during the discharging of the closing spring. This prepares the circuit breaker for the opening operation immediately after it has been closed.

Why do circuit breaker springs need to be charged?

When the springs are gets charged, they store potential energy, which may then be released to successfully operate the breaking mechanism. Proper charging of these springs is essential for ensuring that the circuit breaker can cycle between open & closed states in accordance with operational demands (or) protective measures.
