Abstract

The invention discloses a spring operation mechanism for a high-voltage breaker, belonging to the technical field of transmission and transformation. The spring operation mechanism for a high-voltage breaker comprises a wall plate, a spring tube, a ratchet wheel, a cam, a transmission roller, a connecting rod, a towing plate, a guiding seat, a switching-on wafer, a switching-off wafer, a buffer and a switching on and off spring, wherein a switching-off spring is arranged in the switching on and off spring, the lower end of the switching-off spring is fixed on the guiding seat, the upper end of the switching-off spring is connected with a spring seat of which the upper end is articulated with a bridge-shaped connecting plate and a transmission crutch, the right end of the transmission crutch is articulated with a buffer piston of the buffer, and the upper end of the bridge-shaped connecting plate is articulated with a positioning crutch. In the spring operation mechanism, the switching-off spring and the switching-on spring are arranged in the same tube, thus, the size of the operation mechanism is reduced; and the invention has the advantages of high switching on and off speed, stable mechanical performance, high reliability, and the like.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, in particular to a spring operating mechanism for a high-voltage circuit breaker. technical background [0002] The operating mechanism is the main 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 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 advantages of complex structure, high cost, difficult technical realization, and oil leakage. and other disadvantages; the spring operating mechanism has the characteristics of low cost, simple structure, long service life, and basical...
