Problems solved by technology

[0002] The original terminal block structure in the instrument room of the medium-voltage switchgear has a small installation space. During installation, the parts need to be assembled first, and then installed in the cabinet, resulting in time-consuming installation. At the same time, only double-layer terminals can be installed in the instrument room. It is convenient for wiring and checking, making it inconvenient for wiring installation and maintenance in the instrument room
[0003] In addition to the instrument room, the medium voltage cabinet also includes a busbar room, a cable room and a circuit breaker room, that is, various functional components are installed in the medium voltage cabinet, which makes its internal structure complex and has certain operational safety hazards

Abstract

The invention provides a medium voltage switch cabinet. The medium voltage switch cabinet comprises a cabinet body, each side plate of the cabinet body is in a unilateral double-beat bending way, andthe side plates are connected with an upright; a bus chamber, a cable chamber, a secondary wiring instrument chamber and a circuit breaker chamber are arranged in the cabinet body; the bus chamber, the cable chamber, the secondary wiring instrument chamber and the circuit breaker chamber are isolated through separators; a plurality of bus sleeves in vertical line arrangement in upper and lower arearranged in the bus chamber; one end of each bus is connected with a contact box; an insulator is further arranged in the bus chamber, the cable chamber is arranged below the bus chamber; a mutual inductor and a ground switch connected with the mutual inductor are arranged in the cable chamber; the secondary wiring instrument chamber is arranged at one corner of the cabinet body, and the circuitbreaker chamber is arranged below the secondary wiring instrument chamber. The internal of the switch cabinet disclosed by the invention is reasonable in layout, tidy in wiring, and the busbar arrangement is more convenient, and the maintenance is more convenient.

Description

technical field [0001] The present disclosure relates to the technical field of power distribution, in particular to a medium-voltage switchgear. Background technique [0002] The original terminal block structure in the instrument room of the medium-voltage switchgear has a small installation space. During installation, the parts need to be assembled first, and then installed in the cabinet, resulting in time-consuming installation. At the same time, only double-layer terminals can be installed in the instrument room. It is convenient for wiring and checking, which makes the installation and maintenance of wiring in the instrument room inconvenient. [0003] In addition to the instrument room, the medium-voltage cabinet also includes a busbar room, a cable room, and a circuit breaker room. That is, various functional components are installed in the medium-voltage cabinet, which makes its internal structure complex and poses certain operational safety hazards. Contents of ...
