Abstract

The invention discloses an ultra-high-power spring operating mechanism for a high-voltage circuit breaker, belonging to the technical field of power transmission and transformation. The ultra-high power spring operating mechanism comprises a wall plate, a ratchet wheel, a connecting rod, a fork-shaped connecting plate, a guide seat, a switching-on wafer, a switching-off wafer, a switching-on crutch, a switching-off crutch, a switching-on disc spring set, a switching-off disc spring set and the like. The output power of the spring operating mechanism provided by the invention is greatly improved at the same time that the size of the whole mechanism is reduced; and the ultra-high power spring operating mechanism for the high-voltage circuit breaker has the advantages of high switching-on / off speed, stable performance parameter, high reliability, and ultra-high output power and the like.

Description

technical field [0001] The invention relates to a super-high-power spring operating mechanism for a high-voltage circuit breaker, belonging to the technical field of high-voltage power transmission and transformation. technical background [0002] The spring operating mechanism is an important equipment in the field of high-voltage power transmission and transformation, and 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 spring operating mechanism. 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 the disadvantages of complex structure, high cost, and difficult technical realization; The spring operating mechanism has the characteristics of low cost, simple structure, and long service life...
