The importance of electrical explosion-proof testing
Now, we need to place greater importance on safety testing and inspection work, constantly introducing new safety testing methods and instruments, and promoting the continuous development of electrical explosion-proof safety testing technology. Conducting electrical explosion-proof safety testing in hazardous areas means testing and confirming the safety and reliability of the explosion-proof performance of electrical facilities and equipment operating in hazardous areas. In such hazardous areas, many places can produce explosive gases, some can produce combustible dust, etc. Through those with safety production testing and inspection qualificationsZhongnuo TestingInstitutions shall not dismantle or only partially dismantle the tested facilities and equipment in hazardous areas, and shall supplement them with relevant testing measures. They shall conduct safety inspections on potential hazards of electrical explosion-proof facilities in hazardous chemical areas, control them early, and provide technical support for the safe operation of hazardous chemical enterprises.
The content of electrical explosion-proof safety testing
Conducting electrical explosion-proof testing in hazardous areas, mainly including transformer and distribution systems; Electrical circuit system; Selection of explosion-proof electrical equipment; Infrared testing for overheating conditions; Grounding system and grounding resistance detection; Ultrasonic leakage discharge testing involves the inspection and testing of all electrical explosion-proof safety facilities within the explosion-proof area. In various hazardous areas, explosion-proof safety testing is usually carried out on electrical equipmentZhongnuo TestingOnce problems are found with the electrical equipment model, installation, operation, wiring, grounding, etc., a written report should be immediately issued to the relevant enterprise. At the same time, contact should be made with the safety supervision department to urge the enterprise to take corrective actions. The ultimate goal is to ensure that the explosion-proof testing and inspection of electrical equipment in hazardous areas meet the qualified standards.
Form of electrical explosion-proof safety testing in hazardous areas
1. Model detection
According to the strict regulations of relevant national laws, the explosion-proof labeling of explosion-proof electrical equipment must be standardized, and it can only be implemented after passing the inspection of the national quality inspection department. Design appropriate explosion-proof types, explosion-proof levels, and temperature groups for electrical equipment based on specific working environments.
2. Installation testing
During the installation of electrical equipment, any carelessness can lead to potential losses. If the ventilation and exhaust system is not properly installed and not very smooth, there is also a possibility of explosions in the casing of electrical equipment during electrical operation. So when installing, we must strive for excellence and install according to relevant standards.
3. Line detection
Electrical equipment is often composed of a large number of connected circuits, which are particularly complex. If the connections are not solid, or if there are incorrect connections, or if the insulation layer of the circuit falls off, it may cause short circuits or overloads, resulting in arcing or electric sparks. So, it is necessary to strengthen the inspection of the circuit, especially the sealing of the circuit, to ensure that the connection of the circuit meets the requirements.
4. Grounding detection
Electrical equipment generates static electricity during operation. If there is too much static electricity, sparks may occur during discharge. Therefore, grounding protection measures should be taken to timely discharge the static electricity and prevent explosions. The usual grounding methods include three types: working grounding, electrostatic grounding, and lightning protection grounding. For engineers, it is necessary to choose the grounding method according to the specific working environment, and the grounding should be safe and firm.
Chemical enterprises must regularly maintain and inspect explosion-proof electrical and anti-static facilities in hazardous areas during their production, ensuring that they always operate in normal working condition. For hazardous areas, electricalExplosion proof safety testingWe should follow scientific development, keep pace with the times, strengthen the discovery and invention of new detection methods and means, continuously apply new knowledge and technology, as well as management methods, prevent hidden dangers, and eliminate exposed unsafe factors.
