Shunting conductive protection device of static contact combination switch

Abstract

The invention discloses a shunting conductive protection device of a static contact combination switch. The shunting conductive protection device of a static contact assembly switch comprises an arc elastic sheet. A rectangle hole is formed in the top of the arc elastic sheet. A middle shaft part is connected to the middle part of the side wall of the arc elastic sheet. A blocking hole is formed in the bottom of the side wall of the arc elastic sheet. A contact device is embedded in the rectangle hole. An auxiliary connection block is connected to the middle part of the side wall of a main connection block. The auxiliary connection block passes through the rectangle hole. The outer side wall of the auxiliary connection block is welded with the inner side wall of the rectangle hole. The shunting conductive protection device of the static contact combination switch adopts the middle shaft portion instead of a torsional spring, can shunt a circuit protection device while promoting a fullcontact. As an optimal conductive material, a superconductive nanometer graphene material has strong conductivity and is wearing-resisting and temperature-resisting. As a result, the shunting conductive protection device of the static contact combination switch provides great convenience for usage and maintenance of an electric switch machine, solves a problem of a poor effect of big arc extinguishment of contact resistance of the contact for a long time, solves pressure buffering, reduces operation noise and has a good effect.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a shunt conduction protection device for a combined static contact switch. Background technique [0002] Electromechanical interlocking, especially in the process of track signal operation, a signal in the opening direction that passes or turns around the vehicle operation is realized by the actions of the static contact group and the matching moving contact group on the electric switch machine. . For this reason, the operation of static and dynamic contacts not only has higher requirements on structural performance and service life. Simultaneously, it also lies in being able to achieve the safe operation with the longest use in adapting to various harsh environments. The static contact block switch group is a common technology and belongs to the prior art. [0003] The constant voltage device in the prior art generally adopts two modes: one is to use the deformation...
