‌500 KVA 33 KV step-down distribution transformers need to pay attention to the following points when using them:

‌distribution transformers 'Load current and operating voltage inspection: Ensure that the load current and operating voltage of the oil-immersed transformer are within the normal range to avoid damage to the equipment caused by overload and voltage fluctuations ‌
‌Oil level and oil temperature inspection: Regularly check the oil level, oil color and temperature of the distribution transformer. The upper oil temperature of oil-immersed self-cooling transformers should be kept below 85℃, and that of oil-enhanced air-cooling and oil-enhanced water-cooling transformers should be kept below 75℃.

Inspection of porcelain bushings: Check whether the high and low voltage porcelain bushings are clean, whether there are cracks, damage and flashover discharge marks, and ensure good insulation performance.

Inspection of wiring terminals: Check whether the wiring terminals have poor contact or overheating, ensure that the connection is firm, and avoid overheating problems caused by poor contact.

Inspection of operating sound: The 33kv step-down oil-immersed distribution transformer should have uniform electromagnetic sound during normal operation. If there is uneven sound or abnormal noise, it may be a sign of loose or damaged internal components.

Inspection of cooling system: Ensure that 500 KVA 33 KV The cooling system of the step-down distribution transformer operates normally, the temperature of the heat dissipation pipe is uniform, and there is no oil pipe blockage.

‌Inspection of explosion-proof pipes and desiccant: Check whether the explosion-proof pipe diaphragm of the distribution transformer is intact and whether the desiccant is saturated to ensure that the equipment can safely release pressure under abnormal conditions.

‌Environmental safety inspection: Ensure that the surrounding environment of the oil-immersed distribution transformer is safe before operation, remove flammable materials and fire sources, and avoid welding or cutting around the transformer.

‌Inspection of insulating oil: Regularly check the insulating performance of the insulating oil, replace the aged or seriously contaminated insulating oil in time, and ensure that its insulating performance meets the requirements.

‌Regular maintenance: Including cleaning the surface of the transformer, checking the tightness of the terminal, maintaining the cooling system, etc., to ensure that the equipment is in good condition.
