Abstract
The utility model discloses a buffer-type static contact structure for a vacuum arc-extinguishing chamber. The buffer-type static contact structure comprises a porcelain housing. The upper end of the porcelain housing is installed with a static end cap. The static end cap is installed with a static conductive rod. The inner walls at the upper end of the porcelain housing are respectively provided with a buffer guide slot. The buffer guide slot is internally embedded with a buffer plate. The lower edge of the buffer plate is abutted tightly in the buffer guide slots through buffer spring pieces. The buffer plate is installed with an electric-connection column. The upper end of the electric-connection column is connected with the static conductive rod through flexible connection, and the lower end of the electric-connection column is fixedly connected with a static contact. The buffer-type static contact structure is simple and reasonable in structure, and convenient to install and use; and by adopting the design of arranging the buffer plate in the porcelain housing, the buffer performance of the static contact is effectively improved, so that the static contact can alleviate impact force when impacted by a moving contact, the stability in opening and closing operation is improved, the contact is not easy to bounce, and the service 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 static contact structure of 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 static contact structure of 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 static contact structure of vacuum interrupter, it is characterized in that: include porcelain shell, described porcelain shell upper end is provided with quiet end cap, on described quiet end cap, static conductive rod is installed, 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, and lower end is fixedly connected with fixed contact.
The buffer-type static contact structure of described a kind of vacuum interrupter, is characterized in that: the radome that is coated on electric binding post outer wall is installed on described buffer board.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, employing arranges the design of buffer board in porcelain shell, effectively improved fixed contact shock-absorbing capacity, make fixed contact can slow down impulsive force when clashed into by moving contact, improved minute, the stability of feed motion, contact is difficult for bounce occurs, and has extended useful life of contact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
