Waterproof device for mining motor winding conducting rod

Abstract

The invention discloses a waterproof device for a mining motor winding conducting rod. The device comprises a wiring cavity. The wiring cavity is fixedly arranged in the middle section of the heat conduction shell, a conducting rod is arranged in the heat conduction shell, a circular notch is formed in the lower end of the conducting rod, the winding lead-out wire abuts against the circular notchof the conducting rod, a sealing ring is arranged between the circular notch and the winding lead-out wire, and the heat shrink tube seals the winding lead-out wire through a self-adhesive tape. Silicon rubber is also arranged on the sealing ring. The heat conduction shell comprises a sealing part, a heat dissipation part and a connecting part. The method has the advantages that the slender hole of the sealing part is combined with the hollow part of the heat dissipation part to form an internal heat exchange space, heat generated in the conducting rod and the winding outgoing line is timely transmitted to the interior of the heat exchange space, meanwhile, secondary heat exchange is formed between the thin wall of the heat exchange space and the outside, the conducting rod, the winding outgoing line and the outside humid environment form a sealed space, and the creepage phenomenon is prevented.

Description

technical field [0001] The invention relates to the field of mining motors, in particular to a waterproof and moisture-proof device for mining motor components. Background technique [0002] Due to the relatively humid environment in coal mines, there is often condensed water inside the motor. The condensed water passes through the welding part of the conductive rod and the winding lead-out wire to cause creepage with the casing, resulting in zero insulation resistance, affecting the use of the motor and affecting production efficiency. After applying the waterproof technology of the winding lead wire and the conductive rod, when condensed water is generated, creepage phenomenon caused by water droplets on the surface of the conductive rod and the winding lead wire will occur, which will affect the normal operation of the motor and change the winding lead wire and the winding lead wire. The connection structure of the conductive rod will greatly improve the service life of t...
