Abstract
The utility model discloses a buffer-type vacuum explosion chamber, which comprises a porcelain case, a static end cap and a movable end cap are respectively arranged on an upper end and a lower end of the porcelain case, a static conducting rod is arranged on the static end cap, a movable conducting rod is arranged on the movable end cap, a buffer guide groove is provided on the inner wall at the upper end in the porcelain case, a buffer plate is embedded in the buffer guide groove, the lower edge of the buffer plate is tightly support to the buffer guide groove through a buffer spring, an electric connection column is installed on the buffer plate, the upper end of the electric connection column is connected to the static conducting rod through flexible connection, and a static contact is fixedly connected with the lower end of the electric connection column, a movable contact corresponded to the static contact is arranged on the upper end of the movable conducting rod, and a corrugated pipe is provided on an outer wall sleeve of the movable conducting rod. The design of the buffer plate arranged in the porcelain case is employed, the buffer performance can be effectively increased, the impact force can be alleviated when the static contact is impacted by the movable contact, the stability of separating and closing motion can be increased, generation of bounce phenomenon of the contact is difficult, and the usage life of the contact is prolonged.
Description
Technical field
The utility model relates to vacuum circuit-breaker field, is specially a kind of buffer-type vacuum interrupter.
Background technology
Vacuum circuit-breaker is switchgear common in electrical system, its structure mainly comprises operating mechanism, be built-in with the arc control device unit of current transformer and transmission mechanism etc., have minute, closing speed is fast, compact conformation, the break-make that can fast and effeciently control electrical system, is widely used among various high-voltage electric system.And existing vacuum interrupter in use, moving contact divides, feed motion can clash fixed contact, and fixed contact is caused to larger impulsive force, easily causes occurring between contact bounce, and then cause contact abrasion and calcination, affect the useful life of contact.
Utility model content
The purpose of this utility model is to provide a kind of buffer-type vacuum interrupter, to solve vacuum interrupter traditional in prior art in use, moving contact divides, feed motion can clash fixed contact, fixed contact is caused to larger impulsive force, easily cause occurring between contact bounce, and then cause contact abrasion and calcination, affect the contact problem in useful life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of buffer-type vacuum interrupter, it is characterized in that: include porcelain shell, on described porcelain shell, lower end is separately installed with quiet end cap and moved end lid, on described quiet end cap, static conductive rod is installed, described moved end covers moving conductive rod is installed, in described porcelain shell, upper end inwall is provided with buffering guide groove, in described buffering guide groove, be embedded with buffer board, described buffer board lower edge is pushed against in buffering guide groove by buffering spring sheet, on described buffer board, electric binding post is installed, described electric binding post upper end is connected with static conductive rod by being flexible coupling, lower end is fixedly connected with fixed contact, described moving conductive rod upper end is provided with the moving contact corresponding with fixed contact, and moving conductive rod outer wall cover has bellows.
