Problems solved by technology

The existing low-voltage withdrawable switchgear will generate heat during the working process, so it needs to be dissipated. The existing heat dissipation component is used to dissipate heat, but the existing heat dissipation component will vibrate during the working process, which will affect the use of the switchgear. life

Abstract

The invention discloses a low-voltage draw-out switch device, which belongs to the technical field of electrical equipment, and comprises a device body and a supporting seat, the bottom end of the device body is slidably inserted in the supporting seat, the device body is provided with a plurality of drawer units, and the low-voltage draw-out switch device further comprises an air cylinder, a lifting plate, a heat dissipation assembly, a cylinder body, a damping assembly and an adjusting assembly; when the air blower vibrates during working, the air blower drives the equipment body and the cylinder body to vibrate up and down, the cylinder body further drives the piston to move reversely or oppositely, and at the moment, the piston can be buffered through the elastic buffering assembly and the damping assembly and can also be buffered through air in the cylinder body; the buffering effect is further improved, and effective buffering on the equipment body is achieved when the blower works; the problem that the service life of the switch equipment is affected due to the fact that an existing heat dissipation assembly vibrates in the working process is solved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a low-voltage withdrawable switchgear. Background technique [0002] Low-voltage switchgear is a kind of equipment that transmits and distributes power after the power grid is stepped down. It realizes the functions of control, measurement, protection, and conversion of the power grid. It is an important part of the national power supply and distribution system. Low-voltage withdrawable switchgear is widely used in Due to the increase in infrastructure and power energy investment in production sites, public places, and residential buildings, the low-voltage withdrawable switchgear industry has begun to have a large space for development. The existing low-voltage withdrawable switchgear will generate heat during the working process, so it needs to be dissipated. The existing heat dissipation component is used to dissipate heat, but the existing heat dissipation compon...
