Abstract

The invention relates to a contact isolation chamber for a switch cabinet and the switch cabinet. By the contact isolation chamber, the problems that a contact box of a mobile and opening type switchcabinet in the prior art is not good in cooling and a movable contact and a static contact cannot be normally plugged are solved. The contact isolation chamber for the switch cabinet comprises a shell, wherein an insulation seat and an opening are arranged in the shell, the opening is used for the movable contact to insert, and the static contact is arranged on the insulation seat and is used forexposing one end plugged with the movable contact out of the insulation seat. By changing an original contact box to a relatively large contact isolation chamber and exposing one end, in contact withthe movable contact, of the static, observation during plugging is facilitated; and the static contact and the movable contact are exposed, air cooling in the contact isolation chamber is also facilitated, and the product reliability is improved.

Description

Technical field [0001] The invention relates to a contact compartment for a switch cabinet and a switch cabinet. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and electrical energy conversion in the power system. According to different installation methods of the circuit breaker, it can be divided into removable switchgear and fixed switchgear. In power distribution systems, armored removable metal-enclosed switch cabinets have been widely used. Most of these switch cabinets are composed of four compartments, which are busbar compartment, circuit breaker compartment, cable compartment, and spare handcart compartment. For example, the Chinese utility model patent with the authorized announcement number CN205985930U and the authorized announcement date of 2017.02.22 discloses a metal-enclosed central removable switchgear. The circuit bre...
