Abstract

The invention discloses a gas buffer device for a high-speed repulsion mechanism. The gas buffer device for the high-speed repulsion mechanism comprises a support plate and a cavity fixedly arranged on the support plate, wherein a piston and a spring located under the piston are arranged in the cavity. The gas buffer device for the high-speed repulsion mechanism also comprises a mechanism moving rod penetrating through a central axis of the support plate, the cavity, the piston and the spring, wherein a striking ring is fixed onto the mechanism moving rod and is located above the piston; one end of the mechanism moving rod is connected with a moving contact of a circuit breaker; the other end of the mechanism moving rod is connected with a mechanism lock catch unit. The gas buffer device for the high-speed repulsion mechanism provided by the invention solves the buffer problem of the high-speed mechanism, the damage caused by the impact force on the mechanism during a buffer process is greatly reduced, and the service life and the operation stability of the high-speed mechanism are improved; through changing an arrangement manner, the buffer device can be used for closing buffer of the high-speed mechanism.

Description

technical field [0001] The invention relates to a gas buffer device for a high-speed repulsion mechanism, in particular to a gas buffer device which can be used for breaking and closing the electromagnetic repulsion mechanism of a circuit breaker. Background technique [0002] With the development of my country's power system, the short-circuit current level of the system has risen sharply, and the requirements for the rapidity, stability and reliability of the operation of protective electrical equipment are getting higher and higher. [0003] High-speed electromagnetic repulsion mechanism has been used more and more because of its simple structure and fast breaking speed. [0004] There are defects in the braking and buffering measures of the high-speed electromagnetic repulsion mechanism currently used. Generally, the maximum speed during the action of the repulsion mechanism can reach 5-10m / s, or even higher. At present, most of the buffering methods adopted are hard bu...
