Description

technical field [0001] The invention belongs to the field of electric energy equipment, and in particular relates to an indoor armored removable metal-enclosed switchgear. Background technique [0002] With the continuous development of my country's power grid laying technology, the actual power consumption of my country's power grid has become larger and more concentrated, which has led to an increasing load on the centralized power grid. Electrical devices, fixed switchgear are mainly used in power plants, industrial and mining enterprise power distribution, and substations in the power system for power receiving, power transmission, and control and protection of motors and transformers. 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 safet...

AI Technical Summary

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
