Problems solved by technology

[0002] In high-rise buildings, living areas, power distribution, motor control and lighting distribution equipment of enterprises in working conditions, withdrawable switchgears are often used to make power conversion and distribution control. The existing switchgears are bulky and have low heat dissipation efficiency. During long-term use, it is easy to cause unstable push-pull and jamming, which seriously affects subsequent use and endangers the safety of the equipment

Abstract

The invention discloses a drawing-out type switchgear. The drawing-out type switchgear comprises a switchgear casing, a pedestal structure is arranged in the lower end of the switchgear casing, a cover plate is arranged in the upper end of the switchgear casing, the cover plate is provided with a lightning rod, the upper and lower ends of the switchgear casing are provided with upper and lower ventilating openings respectively, vertical and horizontal insulated separating plates are arranged in the switchgear casing, and the insulated separating plates divide the switchgear casing into four component parts, namely a bus cavity, a function unit cavity, a drawer cavity and a cable cavity. The drawing-out type switchgear of the invention is compact and reasonable in structure design, a drawer can be pulled and pushed smoothly, and the heat radiation and ventilating effects are good.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a withdrawable switch cabinet. Background technique [0002] In high-rise buildings, living areas, power distribution, motor control and lighting distribution equipment of enterprises in working conditions, withdrawable switchgears are often used to make power conversion and distribution control. The existing switchgears are bulky and have low heat dissipation efficiency. During long-term use, it is easy to cause unstable push-pull and jamming, which seriously affects subsequent use and endangers the safety of the equipment. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a pull-out switchgear group, which has a compact overall design and a stable pulling process, and is equipped with an electromagnetic locking mechanism and a thimble ejection mechanism, so that the switchgear has a high safety factor and is easy to...
