Flameproof electrical equipment inspections primarily involve regular checks on operational electrical devices, aiming to identify and address potential issues during use to minimize the risk of explosions. The inspection process is mainly conducted according to the AQ3009-2007 standard, which outlines the specific contents and standards for the inspections.

The inspection content mainly includes the following aspects:

Explosion-proof equipment selection:Verify the rationality of equipment selection, such as whether appropriate explosion-proof electrical equipment is chosen based on the classification of explosive hazardous areas, if there are any installations of Gc-rated equipment in Zone 1, or the use of dust explosion-proof products in gas environments, etc.

Explosion-proof installation and maintenance:Inspect equipment installation and maintenance for compliance with standards, such as whether explosion-proof products are directly mounted against the wall, if there are issues like rust or missing fasteners on the explosion-proof surface, and if any labels are missing.

Cable selection and wiring:Verify the合理性 of cable selection and wiring, such as ensuring the wire diameter is not less than 4mm², and whether wiring is above the pipeline for explosive gases heavier than air.

In terms of testing frequency, as stipulated by the AQ3009-2007 standard, electrical equipment in use must undergo at least one periodic inspection every 3 years and a test report must be issued.
