Daily heat dissipation, overheating, and heat generation maintenance work for explosion-proof distribution boxes

Having a correct handling method for heat dissipation, overheating, and heating issues in explosion-proof distribution boxes is a prerequisite for ensuring the safe operation of the explosion-proof enclosure.。WithStructureprocessingmethodSuch as:

The tightening condition of these electrical connectors is closely related to the safe operation of electrical equipment. As is well known, electrical connectors exhibit thermal expansion and contraction. Due to temperature changes, hot spots, loosening of fasteners, and poor contact of connectors can occur, becoming a "roadblock" to the safe and stable operation of electrical equipment.Secondly, daily inspection of connection components of electrical equipment is also very necessary. During shutdowns and startups, check and tighten major connection components, disassemble and inspect the crimped parts of connection components for oxide layers. If oxide layers are found, they should be promptly polished and treated. Contacts that are burned by more than one-third or silver contacts worn to expose copper should be replaced.。

2. Strengthen patrol inspections, perform electrical temperature measurement, and promptly identify potential hazards.。Restrict inspection personnel, including inspection time, content, records, frequency, etc.。Scientifically and reasonably arrange the inspection time and frequency for electrical management, electrical operation, and electrical maintenance personnel to minimize inspection blind spots; inspection personnel must be conscientious and responsible, checking the integrity of all electrical equipment and accessories, verifying whether standby equipment is normal, and paying attention to whether each explosion-proof distribution box, switch, cable, temperature, sound, voltage, and current are normal. Temperature measurement records should be established in the power distribution room, with temperature checks on electrical equipment within the designated scope each shift and relevant records kept. Problems found must be reported level by level and handled promptly to effectively ensure the safe and stable operation of electrical equipment.。

Clean the motors and power supply cabinets thoroughly.。Hot and humid weather poses a threat to the stable operation of electrical equipment. Excessive dust accumulation on electrical equipment, power supply lines, and power supply equipment can cause short circuits, creepage, and discharge phenomena in electrical equipment, while operating electrical equipment can lead to poor heat dissipation and insulation aging of motors. This requires regular cleaning of dust on power supply lines and power supply equipment. For motors, especially open-type motors, inspection and dust removal should be carried out before summer arrives to ensure good heat dissipation, thereby effectively avoiding unnecessary expenses caused by poor heat dissipation and fluctuations in the price of explosion-proof operation columns.

4. Strengthen outdoor electrical protection, regularly measure insulation, and recommend external maintenance for long-term low insulation. Rainy weather also serves as a test for the protection of outdoor electrical equipment and motor insulation. Electrical protection, especially rain protection for electrical equipment, is particularly critical. Rainy weather brings high humidity, which can easily cause short circuits and leakage in electrical equipment. Meanwhile, severely aged motors are prone to moisture absorption, resulting in decreased motor insulation.On one hand, electrical protection requires promptly closing the doors of on-site control boxes to ensure that electrical protective covers are properly intact, and that protective covers do not leak or seep rain. On the other hand, it is necessary to ensure the insulation of backup electrical equipment. If the insulation of backup equipment does not meet requirements, it cannot serve as a backup, which also plays a role that cannot be ignored in the safe and stable operation of electrical equipment. This requires regular measurement of the insulation of backup electrical equipment, especially hot standby equipment. During rainy weather, the frequency of insulation measurement for backup equipment should be increased compared to normal times. For electrical equipment with long-term insulation failure, it is recommended to send it out for maintenance and servicing to ensure long-term safe standby of backup equipment.
