Problems solved by technology

The existing fixed switchgear is a box-type fixed structure, which generally has the disadvantages of large volume and large space occupation. In particular, there is no pressure relief device between the isolation rooms. Once an internal failure occurs, it is easy to endanger the personal safety of the operating personnel.
At the same time, due to the unreasonable layout of the fixed switchgear, it is not only difficult to overhaul, but also lacks sufficient safety guarantees and safety measures. Operability

Abstract

The invention discloses an indoor metal armored draw out type switch device which comprises a cabinet body and a handcart which can be drawn out. The cabinet body is formed by connecting aluminized zinc plates through bolts. A handcart room, a bus room, a cable room and a relay instrument room are arranged in the cabinet body. The cable room is arranged at the lower part of the cabinet body. The relay instrument room is arranged at the upper part of the front part of the cabinet body. The handcart room is arranged below the relay instrument room. The bus room is arranged behind the handcart room. The cable room is arranged below the bus room. The circuit breaker handcart is arranged in the handcart room. An interlocking device is arranged on the circuit breaker handcart. A heater is arranged on the cable room. The indoor metal armored draw out type switch device provided by the invention has the advantages of novel structure, small volume, reliable interlocking, high protection level, strong interchangeability, convenient operation and maintenance, flexible installation and convenient wiring, and fully meets the requirements of 'five-prevention'.

Description

technical field [0001] The invention relates to a power switchgear, in particular to an indoor metal-clad withdrawable switchgear. Background technique [0002] At present, as an indoor complete set of power distribution equipment for receiving and distributing electric energy, fixed switchgear is mainly used for power receiving, power transmission, control and control of motors and transformers in power plants, industrial and mining enterprises, and substations in power systems. under protection. The existing fixed switchgear is a box-type fixed structure, which generally has the disadvantages of large volume and large floor space. In particular, there is no pressure relief device between each isolation room. Once an internal failure occurs, it is easy to endanger the personal safety of operating personnel. At the same time, due to the unreasonable layout of the fixed switchgear, it is not only difficult to overhaul, but also lacks sufficient safety guarantees and safe...
