AI Technical Summary

Technical Problem

The existing relay protector cooling device has poor cooling effect and does not have moisture-proof function, which leads to the problem of short circuit damage caused by the relay protector.

Method used

A cooling device including a cooling box, a cover plate and a fan is designed, with multiple sets of heat sinks and moisture-proof mechanisms built-in. The exhaust fan drives air into multiple groups of heat sinks, increasing the contact area between the gas and the heat sink, and improving the cooling effect; at the same time, the moisture-proof mechanism absorbs moisture and impurities through the sponge block to prevent short-circuiting of electronic components.

Benefits of technology

It realizes rapid cooling and automatic moisture protection, improves the service life of the relay protector, and avoids the problem of short circuit damage.

Abstract

The invention relates to the technical field of relay protectors, and discloses a cooling device for an electrical engineering relay protector, the cooling device comprises a cooling box, a cover plate and exhaust fans, the cover plate is rotatably connected to the inner wall of the cooling box, the exhaust fans are symmetrically and fixedly connected to the outer wall of the cooling box, a cooling mechanism is arranged at the bottom of the cooling box, and the cooling mechanism is arranged on the inner wall of the cooling box. A moisture-proof mechanism is arranged in the cooling mechanism, a temperature detector is arranged at the top of the cooling box, moisture and impurities in air are absorbed through a filter tank plate, the moisture and the impurities are prevented from making contact with electronic elements on the relay protector, and the problem that the electronic elements are short-circuited and damaged is solved; according to the relay protector, the service life of the relay protector is prolonged, the sponge block is intermittently extruded through the arc-shaped groove plate, the effect of dewatering the sponge block is achieved, the sponge block is blocked through the baffle, the sponge block is prevented from popping out when being extruded, and the stability of the sponge block for absorbing water and impurities is improved.
