Problems solved by technology

Therefore, power users and the switch industry agree that the spring operating mechanism is the most reliable. However, although the existing spring mechanism does not have the defects and problems of the first three operating mechanisms, its shortcoming is that it cannot be used on high-voltage circuits above 252KV. The domestic spring operating mechanism can onl

Abstract

The surface-contacted sliding four-bar linkage disc-reed storing energy operation mechanism includes motor, derailleur, drive gearing device, open, close disc-reed storing energy component, cam is mounted on output axes of motor and derailleur, and contacts with column-type idler wheel which is mounted on fan-shaped arm, the other end of the fan-shaped arm possesses drive claw, needle of claw is half-round, tooth of driver is also half-round, and joggled with each other to be surface contacting. The driver possesses column-type pin roll which is at middle groove-type gap of open and close gate connecting rod and close connecting board, sliding four-bar linkage on-off structure is composed, structure of the invention is novel, original and scientific, design is reasonable, the invention adopts surface-contacted arthrosis-type high load storing energy system and sliding four-bar linkage drive on-off structure technique and disc-reed with high energy density as storing energy component, it can obtain 9000 joule operation work, fits for 252KV to 363KV high voltage breaker. It adopts gate with pin axes to decrease energy loss and wallop.

Description

(1) Technical field [0001] The invention relates to an operating mechanism of a circuit breaker, in particular to a disc spring energy storage operating mechanism of a surface-contact sliding four-link transmission of a high-voltage circuit breaker with relatively large operating work. (2) Background technology [0002] The circuit breaker is a major equipment in the high-voltage power transmission and transformation circuit, and the operating mechanism used to close and open the circuit breaker is also an essential and important supporting equipment. At present, the sulfur hexafluoride circuit breaker commonly used in my country's high-voltage power transmission and transformation industry and its matching operating mechanism are roughly divided into four types, namely, pneumatic mechanism, hydraulic operating mechanism, disc spring energy storage hydraulic operating mechanism and Spring operating mechanism, although the first three operating mechanisms can work in higher vo...
