Abstract

The invention relates to the field of electrical cabinet equipment, and discloses a high and low voltage switchgear with protective performance, which is used for installing an electrical cabinet shell of electrical equipment. In the installation cavity of the device, a plurality of installation cavities are also provided with retractable airbags for driving the movement of the telescopic plates, and a pneumatic component capable of spraying dry powder in a plurality of single cabinets is also installed on the installation frame. By shrinking the installation cavity, the invention avoids the expansion of danger caused by factors such as heat conduction, and at the same time, when the telescopic plate moves to the maximum extent, it just completely covers the heat dissipation hole, which further ensures the sealing of the installation cavity in the event of an emergency, and strictly controls the expansion of danger. , and can also be covered by dry powder to isolate the open flame and exhaust air to prevent the occurrence of fire in the single cabinet, so as to further protect the electrical cabinet to fully ensure the safety of its use.

Description

technical field [0001] The invention relates to the field of electrical cabinet equipment, in particular to a high and low voltage switchgear with protective performance. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of the components. Electrical cabinets are generally made of two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel sheets are softer than hot-rolled steel sheets, and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] In the prior art, a Chinese patent document with a publication number of CN111478218B proposes an independent insulation drawer-type low-voltage switchgear with anti-diffusion, which realizes the full wrapping protec...
