What are the main items inspected in AQ3009 explosion-proof electrical testing? Explosion-proof electrical equipment in use must undergo regular explosion-proof inspections to identify any issues that may arise during operation, thereby minimizing the risk of explosions. Many customers have asked what aspects are checked by explosion-proof testing agencies, so here the editor summarizes them. The selection of explosion-proof equipment is inappropriate; for example, Gc-type equipment is installed in Zone 1 areas, dust-proof products are used in environments with gases, and non-explosion-proof products are installed in explosion-proof areas. The installation and maintenance of explosion-proof systems are also inadequate: for instance, flame-retardant products are installed directly against walls, the flame-retardant surfaces rust, there is a lack of fasteners, and nameplates are missing. The selection and wiring of cables are not appropriate; generally, the cross-sectional area of the wires used for connections should be no less than 4 mm2, and explosive gases that are heavier than air should be wired above pipes, among other requirements. https://pica.zhimg.com/80/v2-36f3c9bd1f925949755529763805b439_1440w.webp?source=d16d100b
The AQ3009 explosion-proof electrical inspection focuses on the following aspects: 1. Whether the selection of explosion-proof equipment is appropriate: It checks whether equipment that meets explosion-proof standards is installed in the appropriate areas, such as whether explosion-proof products are used in gas-filled environments and whether non-explosion-proof products are installed in explosion-proof areas. 2. Are the explosion-proof installation and maintenance proper: Check whether the installation of explosion-proof equipment complies with relevant standards, such as whether the flame arrestor products are installed correctly, whether the flame arrestor surfaces are rusted, and whether there is a lack of fasteners and nameplates. 3. Are the cable selection and wiring appropriate? Check whether the choice of cables and their wiring meet the requirements, such as whether the diameter of the wires used for power connection is at least 4 mm, and whether they are properly wired above the pipes carrying explosive gases. By conducting regular inspections of explosion-proof electrical equipment, issues that arise during use can be identified and resolved in a timely manner, thereby minimizing the risk of explosions. The above are the main aspects of AQ3009 explosion-proof electrical testing. .
