AI Technical Summary

Problems solved by technology

At present, most of the accidents that occur during the operation of circuit breakers are caused by the failure of the operating mechanism. The characteristics are: the structure is relatively complex; the operating power is large; the transmission part moves at a high speed and the action process is fast.
However, the current institutions cannot meet the above requirements

Abstract

The invention relates to a V-type spring mechanism which comprises two baffles, a drive shaft, an energy storage shaft, a big gear, a small gear, a ratchet wheel, a detent, a ratchet pin, an upper drive plate, an upper breach shaft, a cam, an upper stroke switch, an upper driving lever, a crank arm, a connecting rod, a lower breach shaft, a lower driving lever, a lower stroke switch and a suspending spring. Compared with a traditional spring mechanism, the spring mechanism has the advantages of small size, low cost, stable performance, high universality, convenient debugging and the like.

Description

technical field [0001] The invention belongs to products in the field of high-tech transformation of traditional industries, and relates to a V-shaped spring mechanism used in high-voltage switchgear, in particular to a V-shaped spring mechanism used in circuit breakers. Background technique [0002] The operating mechanism of the circuit breaker is a device used to close the circuit breaker, maintain the closed state and open the circuit breaker. Therefore, the operating mechanism includes a closing mechanism, a mechanism (hook) for maintaining the closing state, and an opening mechanism. At present, most of the accidents that occur during the operation of circuit breakers are caused by the failure of the operating mechanism. The characteristics are: the structure is relatively complex; the operating power is large; the movement speed of the transmission part is high, and the action process is fast. However, the current institutions cannot meet the above requirements. C...
