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 haveExplosion proof certificateOr the explosion-proof certificate may have expired or been forged, the nameplate may not match the explosion-proof certificate, the explosion-proof type selection may not comply, gas explosion-proof electrical equipment and dust explosion-proof electrical equipment may be mixed, the wiring of explosion-proof electrical equipment installation may be improper, the circuit may not be grounded, drilling holes or installing buttons on the explosion-proof shell may cause explosion-proof failure, and explosion-proof electrical equipment may be subjected to corrosion, high temperature, and intense vibration for a long time.
Regarding explosion-proof electrical appliances in use,AQ 3009-2007According to the standard of "Electrical Safety Explosion Prevention Specification for Hazardous Areas", explosion-proof electrical appliances in use must be at least3Annual commission withexplosion-proofProfessional qualification testing centers conduct performance, installation, maintenance, and other testing of explosion-proof electrical appliances. Any non compliant items must be promptly rectified, 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.
If the enterprise needs to conduct regular inspections on such sites and prepare explosion-proof inspection reports, it only needs to provide the following information to Zhongnuo Testing:
1. Explosion proof area division diagram
2. List of electrical equipment in explosion-proof areas
3. Explosion proof area area
4. Copy of explosion-proof certificate for explosion-proof electrical equipment
If the enterprise only wants to test a part of the equipment or is unclear about the information provided, Zhongnuo Testing can provide targeted solutions and suggestions.
