Moisture-proof mechanism of alternating-current metal closed looped network switchgear

Abstract

The invention relates to the technical field of electrical equipment, and discloses a moisture-proof mechanism of a alternating current metal closed looped network switchgear. The moisture-proof mechanism comprises a cabinet body, wherein a partition plate is fixedly arranged on the upper side in the cabinet body, the cabinet body is divided into a dehumidification cavity and a working cavity through the partition plate, baffle nets are fixedly arranged on the left side and the right side in the dehumidification cavity, a drying agent filler is filled between the two baffle nets in the dehumidification cavity, an air inlet hole is formed in the right side wall of the dehumidification cavity, a heat dissipation fan is fixedly arranged on the left side in the dehumidification cavity, a ventilation pipe is fixedly connected to the left side wall of the dehumidification cavity, a set of heat dissipation holes are formed in the left side wall of the cabinet body, a sealing cover is arranged on the outer side of the set of heat dissipation holes, and the right side wall of the sealing cover is fixedly connected with the left outer side wall of the cabinet body. According to the invention, the moisture-proof mechanism can effectively prevent working elements in a switchgear from being affected with damp and damaged due to long-term contact with moisture, is good in moisture-proof effect, and prolongs the service life of the switchgear.

Description

Technical field [0001] The present invention relates to the technical field of electrical equipment, and is specifically a moisture-proof mechanism for an alternating metal closed loop switching device. Background technique [0002] AC metal closed switch equipment is a new generation of medium-voltage electrical appliances that introduce advanced technology and designed according to domestic agricultural power and domain network transformation requirements, has a small size, light weight, beautiful shape, easy operation, long life, high long life, high Parameters, non-pollution, less maintenance, etc., as the acceptance and distribution of electrical energy. [0003] At present, the AC metal closed loop switching device is in production, generally opens a plurality of heat dissipation holes on the sidewall of the casing to facilitate timely generation of heat generated in time, but this method can cause external wet. The gas enters the inside of the casing, causing damage to the...
