Description

technical field

[0001] The invention relates to the technical field of electrical equipment, in particular to an AC metal armored removable switchgear for protecting circuits. Background technique

[0002] AC metal-enclosed switchgear, commonly known as switchgear, is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. It can control, protect and detect circuits, and can also be used in places with frequent operations. It is currently the most widely used power distribution switchgear. In recent years, with the vigorous development of industry, there is a large demand for power supply and distribution switchgear, and after the transformation of urban and rural power grids, the incentives of market demand, government policy support, the introduction of foreign advanced products, Sino-foreign joint ventures, and the rapid development of private enterprises The rise has effectively promot...
