Transformers have become an indispensable piece of equipment in our lives. As large as some hospitals, our daily work enterprises, or factories, as small as our homes, transformers have been installed to help us stabilize the voltage and provide us with To provide a more convenient and safer electricity environment, but sometimes the transformer often has some small problems that cause us a lot of trouble, so preventive work is particularly important.

,

1. When the transformer is transported and stored, it is necessary to do a good job of sealing, and take waterproof and moisture-proof measures when installing and using it. Pay special attention to whether the top of the casing, the explosion-proof membrane, the top of the oil pillow, and the respiratory tract are well sealed.

2. When installing a transformer with strong oil circulation, ensure that the connection between the body and the cooling system is well sealed, and the gasket is installed correctly and kept intact. When replacing rubber pads, samples of rubber pad materials with unknown properties should be sampled for oil resistance test.

3. The water cooler and submersible pump should be tested for leaks in accordance with the manufacturer's instructions before installation. Operating and standby cooling oil must ensure that the oil pressure is greater than the water pressure.

4. The explosion-proof cylinder should be connected to the oil pillow, or connected to the atmosphere via a respirator, and drain the water under the oil pillow regularly.

5. The oil seal of the respirator should be refueled for maintenance and kept unblocked.

6. Before the transformer is put into operation, pay special attention to removing the internal air. For example, the remaining air should be removed from the high-voltage casing flange, riser seat, dead space in the oil pipeline, and the top of the oil cooler. Before the strong oil circulating transformer is installed and put into operation, all cooling equipment should be started to circulate the oil for a period of time to discharge the residual air.

7. When charging or filtering oil from the oil conservator with electricity, the water in the oil conservator should be drained first, and oil should not be injected from the lower part of the transformer to prevent air from bringing water and debris from the bottom of the tank into the coil.

8. When the gas sends a signal, take the gas in time to determine the composition, take the oil sample for chromatographic inspection, find out the cause, and troubleshoot in time.

To prevent the insulation breakdown of the transformer, it is necessary to protect the transformer from moisture. Most of the insulation breakdown is due to the damp of the transformer, and the accumulation of time leads to the insulation breakdown of the transformer.
