Problems solved by technology
The operating mechanisms of high-voltage circuit breakers are mainly divided into hydraulic and spring operating mechanisms. The hydraulic operating mechanism has the advantages of short opening and closing time and stability, but has complex structure, high cost, high technical difficulty, and easy oil leakage; spring operating mechanism Low mechanism cost, simple structure, long service life, basically maintenance-free, etc., suitable for wide use on high-voltage circuit breakers
[0003] The Chinese utility model patent with the application number of 201220353046.8 discloses a circuit breaker energy storage and clutch mechanism. The disclosed energy storage spring arm directly stretches the energy storage spring, and the effective angle of the force will change with the rotation of the energy storage spring arm. , do more useless work, causing impact on the support of the circuit breaker mechanism, affecting performance such as life

The invention relates to the technical field of electrical equipment, in particular to an energy storage control device of a breaker. The device comprises a center shaft arranged in a device box and used for driving a breaker mechanism to make movements, and an energy storage device, a switch-on device, a switch-off device, a reset device and a center shaft one-way rotating device, which are connected to the center shaft; the energy storage device comprises an energy storage motor, a large chain wheel, a small chain wheel, an energy storage disk, an on-off device, an energy storage auxiliary switch and an energy storage spring, a chain or belt is wound on the energy storage disk in the circumferential direction, one end of the chain or belt is connected with the energy storage disk, and the other end of the chain or belt is connected with the energy storage spring. The energy storage control device has the advantages that the energy storage spring is pulled by the chain or belt by driving the energy storage disk to compress stored energy, the effective angle of the acting force of the energy storage spring can always be in a maximum level, on the one hand, the effective work of theenergy storage spring is improved, on the other hand, impact of the lost work on the device body is reduced, and the device service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an energy storage control device for a circuit breaker. Background technique [0002] The circuit breaker is the main equipment in the field of high-voltage power transmission and transformation, and the operating mechanism of the circuit breaker is an important part of the high-voltage circuit breaker. The closing and opening operations of the high-voltage circuit breaker are realized through the operating mechanism of the circuit breaker. The energy storage and clutch of the circuit breaker are one of the most important components of the action of the entire circuit breaker mechanism, and are the prerequisites for the high-voltage circuit breaker to perform closing and opening operations. The operating mechanisms of high-voltage circuit breakers are mainly divided into hydraulic and spring operating mechanisms. The hydraulic operating mechanism has the advantages o...
