Main Content of Regular Inspection for Explosion-Proof Electrical Equipment
1. Model Inspection
In strict accordance with relevant laws, the explosion-proof marking of explosion-proof electrical equipment must be standardized, and it can only be implemented after passing the relevant explosion-proof standard inspection and obtaining the qualification. It is necessary to design the appropriate explosion-proof type, level, and temperature class information for electrical equipment based on the specific working environment.
2. Installation Inspection
During electrical equipment installation, any oversight can potentially lead to losses. For instance, if the ventilation and exhaust system is not properly installed and not adequately ventilated, there's also a risk of explosion due to the electrical equipment's casing during operation. Therefore, meticulous attention must be paid during installation, and it is essential to follow relevant standards meticulously.
3. Wire inspection
Electrical equipment is often composed of a large number of interconnected wires, which can be particularly complex. If not properly connected, or if there are incorrect connections, or if the insulation of the wires peels off, it may lead to short circuits or overloads, resulting in arcs or sparks. Therefore, it is crucial to strengthen the inspection of circuit connections, especially the sealing of wires, to ensure that the connections meet the requirements.
4. Grounding Inspection
Electrical equipment generates static electricity during operation. If there's an excessive amount of static, sparks may occur upon discharge. Therefore, proper grounding protection is crucial to promptly dissipate static electricity and prevent explosions. Common grounding methods include working grounding, static grounding, and lightning protection grounding, etc. Engineers must select the appropriate grounding method based on the specific working environment and ensure that the grounding is both safe and secure.
