Major contents of regular inspection for explosion-proof electrical equipment
1. Model Inspection
In strict accordance with relevant laws, explosion-proof electrical equipment must have standardized explosion-proof markings, and must pass the corresponding explosion-proof standard inspection and obtain approval before implementation. It is necessary to design the appropriate explosion-proof type, level, and temperature class for electrical equipment based on the specific working environment.
2. Installation Inspection
During electrical equipment installation, any oversight can lead to potential losses. For instance, if the ventilation and exhaust system is not properly installed and not functioning smoothly, or if the electrical equipment's casing poses an explosion risk during operation, it is crucial to install with utmost precision and adhere to relevant standards.
3. Wire Inspection
Electrical equipment is often composed of numerous wiring connections, which can be particularly complex. If the connections are not secure, or if there are incorrect connections, or due to the insulation layer of the wires peeling off, it may lead to short circuits or overloads, resulting in arcs or sparks. Therefore, it is crucial to strengthen the inspection of circuit integrity, especially the sealing of the wires, to ensure the connections meet the required standards.
4. Grounding Inspection
Electrical equipment generates static electricity during operation. If there's an excess of static, a spark may occur during discharge. Therefore, it's crucial to implement proper grounding protection to promptly discharge 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 safe and secure.

We understand that places involving explosive gases and dust need regular explosion-proof electrical inspections. What exactly is checked during these inspections?
Electrical Explosion-Proof Safety Inspection for Hazardous Areas
1. Model Inspection
Under strict legal regulations, explosion-proof electrical equipment must have standardized explosion-proof markings, and can only be implemented after passing the corresponding explosion-proof standard inspections. It is necessary to design the appropriate explosion-proof type, level, and temperature class 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, it may not be adequately ventilated, and the outer shell of electrical equipment can pose an explosion risk during operation. Therefore, it is crucial to strive for perfection and ensure that the installation adheres to relevant standards.
3. Line Check
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 is an excessive amount of static, a spark can occur during discharge. Therefore, proper grounding protection must be in place to promptly discharge the static 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, ensuring that the grounding is both safe and secure.
Chemical companies must regularly maintain and inspect explosion-proof electrical and static-dissipative equipment in hazardous areas to ensure they are always in normal working condition. For dangerous sites, electrical explosion-proof safety inspections should be based on scientific development and keep pace with the times. Strengthen the discovery and invention of new inspection methods and means, continuously apply new knowledge and technology, as well as management methods, to prevent potential hazards and eliminate unsafe factors.
