Embodiment Construction
[0020] A 6300A large-capacity vacuum switch that can be equipped with a cabinet, including a moving contact 1, a static contact 2, a main bus bar 3, and a branch bus bar 4. The moving contact is in the form of vertical double contacts (that is, there are left and right contacts parallel vertically arranged), the static contact is vertically inserted between the vertical double contacts, and contacts with the vertical double contacts.
[0021] The static contact 2 and the branch busbar 4 are clamped and connected through the clamp 5, and the static contact is clamped in the branch busbar. (Or one-way parallel connection between the static contact and the branch bus through the connecting piece 6). The main busbar and branch busbar adopt the form of tubular line. The main busbar and the branch busbar are clamped and connected by a clamp 7, and the main busbar is clamped in the branch busbar. There is a temperature measuring probe 8 for measuring the temperature of the busbar. ...

The invention discloses a large capacity vacuum switch of a matchable tank of 6300A, comprising a moving contact, a static contact, a main bus-bar and a branch bus-bar; the moving contact is in a vertical double-contact form; the static contact is vertically inserted between the vertical double contacts to be contacted with the vertical double contacts; the invention has reasonable structure and adopts the moving contact of the vertical double contact form, which can effectively reduce the current density and improve the thermal property of heat convection. The invention adopts a tubular bus-bar form; the electric fields are uniformly arranged; the mechanical intensity for anti-electric power is high; the main bus-bar and the branch bus-bar are connected by a clamp in a hooping way; the connection is firm and the contact effect is good.
Description
Technical field: [0001] The invention relates to a large-capacity vacuum switch. Background technique: [0002] The existing large-capacity vacuum switch adopts a horizontal single moving contact, high current density, and unsatisfactory thermal performance of heat convection. There are also deficiencies in the invention, which affect the work performance. Invention content: [0003] The purpose of the present invention is to provide a large-capacity vacuum switch with reasonable structure and good working performance, which can be equipped with a cabinet of 6300A. [0004] Technical solution of the present invention is: [0005] A 6300A large-capacity vacuum switch that can be equipped with a cabinet, including moving contacts, static contacts, main busbars, and branch busbars. The vertical double contacts are in contact with the vertical double contacts. [0006] The static contact and the branch busbar are connected in a clamping type, and the static contact is clam...
