Frequent safety accidents in low-voltage transformers: the importance of maintenance and testing

حديثاً, أ low-voltage transformer safety accident occurred in a certain city. It is reported that there was a serious overload inside the transformer, causing the insulation oil to be subjected to high temperature or arc action, which decomposed and produced a large amount of hydrocarbon mixed gas. These gases accumulate inside the transformer, causing a sharp increase in pressure, ultimately leading to structural damage to the transformer oil tank (primary transformer explosion). After the explosion, insulating oil, mixed gas, and oil mist were violently released outward through the crack in the transformer oil tank. These substances pose a danger to the surrounding environment and personnel and trigger secondary explosions, further expanding the consequences of the accident.

After the accident, relevant departments quickly activated emergency plans and carried out rescue work. They first controlled the fire on site and then used professional equipment to cool the leaked transformer to prevent the further spread of the fire. في نفس الوقت, firefighters use foam extinguishers to cover the leaked insulating oil to reduce its flammability. After emergency response, the fire was finally controlled, and the accident did not cause any casualties.

This accident reminds us that as an important equipment in the power system, the safe operation of low-voltage transformers is crucial for ensuring the safety of people's lives and property. لذلك, relevant departments and enterprises should strengthen the maintenance and testing of transformers in their daily work and promptly discover and deal with potential safety hazards. فضلاً عن ذلك, safety training for relevant personnel should be strengthened to enhance their ability and awareness to respond to sudden accidents.

The precautions for using low-voltage transformers include the following points:

1. Installation environment: Low voltage transformers should be installed in a dry, well-ventilated, dust-free, and noncorrosive gas environment to avoid the impact of moisture, ارتفاع درجة الحرارة, تلوث, and other issues on the performance and service life of transformers. في أثناء, transformers should be installed on a sturdy foundation to maintain their operation.

2. Wiring safety: Safety operating procedures should be followed to ensure correct and secure wiring. For the wiring on the high-voltage and low-voltage sides, corresponding electrical safety regulations should be followed to avoid safety accidents such as electric shock.

3. صيانة: Low voltage transformers require regular maintenance, including cleaning, inspection, measurement, إلخ. أثناء الصيانة, attention should be paid to checking the temperature, sound, appearance, and other conditions of the transformer, as well as testing and adjusting the electrical performance to detect and handle abnormal situations promptly.

4. Safe operation: When operating transformers, safety operating procedures should be followed to avoid safety accidents caused by improper operation. على سبيل المثال, during the operation of transformers, operations such as overloading and sudden power outages should be avoided.

5. Regular testing: Low voltage transformers should be regularly tested, including electrical performance testing, insulation resistance testing, إلخ., to ensure their normal performance, أمان, والموثوقية. During the testing process, attention should be paid to the correct use of testing methods and instruments to avoid misjudgments or missed detections.

6. الصيانة الوقائية: To ensure the normal operation of low-voltage transformers and extend their service life, preventive maintenance is required. على سبيل المثال, regular inspections, cleaning, measurements, and replacing vulnerable parts as needed. أثناء الصيانة, attention should be paid to correct maintenance methods and tools to avoid unnecessary damage or damage to the transformer.

7. Emergency response: If an emergency or safety accident occurs during use, appropriate measures should be taken immediately. على سبيل المثال, if a transformer catches fire, measures such as immediately cutting off power, using fire extinguishers to extinguish the fire, and following relevant emergency response procedures should be taken.
