Abstract

The invention relates to a readiness indicating component, and in particular to a circuit breaker integrated energy storage and release state and turning-on readiness indicating component disposed ona circuit breaker operating mechanism and an operating method thereof. The circuit breaker integrated energy storage and release state and turning-on readiness indicating component comprises an operation box, wherein the operation box is provided therein with a readiness indicating component, a turning-on / turning-off indicator and a turning-on button; the readiness indicating component is rotationally fixed to the operation box through a first shaft; the turning-on button positionally controls the operation box through a turning-on half axle; and the turning-on / turning-off indicator is rotationally positioned along the operation box. In the circuit breaker integrated energy storage and release state and turning-on readiness indicating component and the operating method thereof, the integrated structure that realizes status indication in conjunction has the advantages of simple principle, reliable operation, convenient installation, and low cost.

Description

technical field [0001] The invention relates to a ready indicating component, in particular to a circuit breaker integrated energy storage, energy releasing state and closing ready indicating component arranged on a circuit breaker operating mechanism and an operating method thereof. Background technique [0002] Circuit breakers are important components in power transmission and distribution equipment. In order to enable the operator to accurately judge the energy storage / energy release state of the circuit breaker operating mechanism and whether the circuit breaker is in the closing state and avoid invalid closing, it is usually necessary to provide a visual energy storage / energy release state and the closing state indicator. [0003] In the prior art, the indicator is implemented by a combination of two components, that is, an energy storage / discharge indicator and a closing ready indicator are required to cooperate with each other to realize the status indication, such ...
