Explosion-proof and anti-corrosion intelligent circuit breaker

Abstract

The explosion-proof anticorrosion intelligent breaker of invention relates to a switch, and comprises an explosion-proof case, a breaker, a blast gas detector and an alarm; the explosion-proof case is formed by sealing a case body with a case cover; a plurality of cable ports are arranged below the explosion-proof case, and connecting portions between the cable ports and the explosion-proof case are sealed by a sealant; the case cover is provided with a rotary handle; the rotary handle inserts into the explosion-proof case and is matched with a breaker switch arranged in the explosion-proof case; the blast gas detector is arranged in the explosion-proof case, and a signal input end of the detector is respectively in circuit connection with a plurality of blast gas sensors, and a signal output end is in circuit connection with the alarm arranged outside the case cover. The explosion-proof anticorrosion intelligent breaker not only has a normal explosion-proof case sealing property, and a nitrogen storage tank is arranged inside; when external gas enters the case body and before the concentration gradually reaches the combustion blast critical value, the nitrogen is gradually released so as to gradually dilute the flammable and combustible gas concentration, thus preventing combustion blast, and ensuring personal and property safety.

Description

technical field [0001] The invention relates to a switch, in particular to an explosion-proof and anti-corrosion intelligent circuit breaker. Background technique [0002] Circuit breakers installed in flammable and explosive environments are usually located in a sealed explosion-proof box to prevent flammable and explosive gases from contacting the circuit breaker and avoid other explosions caused by electric ignition. However, the usual explosion-proof boxes only use physical Insulation, unless the gap is completely welded, it is inevitable that the outside gas will enter, and when the outside gas enters, even if there are alarm measures, people usually will not have time to deal with it. In this area, if a combustion explosion occurs, it will cause major losses. , causing harm to personal and property safety. Contents of the invention [0003] The object of the present invention is to provide an explosion-proof and anti-corrosion intelligent circuit breaker in order to...
