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

With the increasing popularity of explosion-proof appliances, many explosive hazardous areas have installed and used explosion-proof 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, so-called explosion-proof electrical appliances do notZhongnuo TestingExplosion proof certificate orExplosion proof certificateExpiration, falsification, inconsistency between nameplate and explosion-proof certificate, inconsistent selection of explosion-proof type, mixed use of gas explosion-proof electrical equipment and dust explosion-proof electrical equipment, improper wiring of explosion-proof electrical equipment, ungrounded wiring, drilling holes in explosion-proof shells, installation of buttons causing explosion-proof failure, long-term corrosion, high temperature, and intense vibration of explosion-proof electrical equipment.

For explosion-proof electrical appliances in use,AQ 3009-2007The standard for Electrical Safety and Explosion Protection in Hazardous Areas stipulates that:Zhongnuo TestingExplosion proof electrical appliances at least3Entrust a testing center with explosion-proof professional qualifications once a year to conduct performance, installation, maintenance, and other tests on explosion-proof electrical appliances. For any non conformities detected, corrective measures must be taken in a timely manner, and the inspection report and rectification situation must be filed with the safety production supervision and management department.

Conducting explosion-proof on-site inspections on 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.
