Abstract

The invention discloses a buffer device for a quick switch, which comprises a support flange, one side of the support flange is fixedly connected with oppositely arranged holding brackets, the end parts, far away from the support flange, of the two holding brackets are connected with support rod seats, the end parts, far away from the holding brackets, of the support rod seats are fixedly connected with disc spring sleeves, and pressure spring rods are sleeved in the disc spring sleeves; the buffer structure is fixedly connected to one side of the supporting flange, a cross-shaped transmission shaft is fixedly connected to the end, away from the supporting flange, of the buffer structure, and the two opposite ends of the cross-shaped transmission shaft are connected with the ends of the pressure spring rods respectively. The device is convenient to connect, simple in equipment debugging and mounting, small in friction force in the transmission process, novel in oil buffer structure, capable of meeting the action characteristic of a rapid switch, capable of keeping buffer integrated design, simple in overall structure, small in occupied space and small in transmission friction force of parts, and the service life of the equipment is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of electrical buffering equipment, and particularly relates to a buffering device for a quick switch. Background technique [0002] As a new type of power equipment, the fast switch can realize the rapid cut-off in the first half-wave of the short-circuit current of the system. The electromagnetic repulsion mechanism used in the circuit breaker has a faster closing and opening speed than that of the conventional circuit breaker. Therefore, it needs a more reliable and better performance buffer mechanism, and the existing buffer device is seriously worn between the parts during use, which is very difficult. It is easy to get stuck, resulting in poor buffering effect. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a buffer device for quick switch, which solves the problems of poor buffer performance and poor reliability of the existing buffer device. [0004] The techn...
