Which regulation does the three-year explosion-proof testing come from?


With the increasing popularity of explosion-proof electrical appliances, many explosive hazardous areas have installed and used explosion-proof electrical appliances. Many end users believe that as long as explosion-proof electrical appliances are installed in explosive hazardous areas, everything will be fine. In many cases, the so-called explosion-proof electrical appliances do not haveZhongnuo TestingExplosion proof certificate orExplosion proof certificateExpired, forged, etc. The nameplate does not match the explosion-proof certificate, the explosion-proof type selection does not comply, gas explosion-proof electrical equipment and dust explosion-proof electrical equipment are mixed, the wiring of explosion-proof electrical installation is improper, the circuit is not grounded, drilling holes and installing buttons on the explosion-proof shell cause explosion-proof failure, and explosion-proof electrical equipment is subjected to corrosion, high temperature, and intense vibration for a long time.

 

Regarding explosion-proof electrical appliances in use,AQ 3009-2007The standard "Electrical Safety Explosion Prevention Specification for Hazardous Areas" stipulates that:Zhongnuo TestingExplosion proof electrical appliances at least3Entrust a testing center with explosion-proof professional qualifications once a year to conduct testing on the performance, installation, maintenance, etc. of explosion-proof electrical appliances. Any non compliant items must be rectified in a timely manner, and the inspection report and rectification situation must be filed with the safety production supervision and management department.

 

Conducting on-site inspections of explosion-proof electrical appliances in use is not only a requirement of the safety production department, but also a concern of the enterprise for its own life and property safety.
