Abstract

The invention belongs to the technical field of substations, and particularly relates to a mining explosion-proof mobile substation, which comprises a mining explosion-proof high-voltage vacuum switch, and is characterized in that a high-voltage sleeve is fixedly arranged at the right end of the mining explosion-proof high-voltage vacuum switch; the mining explosion-proof high-voltage vacuum switch is fixedly connected with a high-voltage bushing through a first bolt, an elastic pad and a gasket, a wire holder assembly is fixedly arranged on the front side wall of the high-voltage bushing, a word plate is fixedly arranged at the lower end of the wire holder assembly through a copper rivet, and a box is fixedly arranged at the right end of the high-voltage bushing. A box cover is fixedly arranged at the upper end of the box, the heat productivity of the mining explosion-proof dry-type transformer is effectively improved, the output power of the transformer is increased, and the situation that the service life of the transformer is affected due to the fact that the interior of the transformer is at a high temperature for a long time is prevented.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a mine flameproof mobile substation. Background technique [0002] Mining explosion-proof mobile substation, referred to as mobile substation, is mainly used in dangerous places containing gas and coal dust explosions in coal mines, such as KBSGZY mine explosion-proof mobile substation, as a primary voltage of 10KV or 6KV, secondary voltage 380V, 660V, 1140V, 3300V power supply and transformation equipment. The most commonly used configuration of mobile substation is composed of three parts: mine explosion-proof dry-type transformer, mine explosion-proof mobile substation high-voltage vacuum switch and mine explosion-proof mobile substation intelligent low-voltage protection box. substation. [0003] However, during the use of the existing flameproof mobile substation for mining, the heat dissipation is poor and the mechanical strength is low. The inside of the transformer ...
