Let the substation run smoothly with three injections and one avoidance

Let the substation run smoothly with "three injections and one avoidance"!

1. Pay attention to lightning protection.

The casing of a box transformer is usually installed directly outdoors, and thunderstorms often occur in summer. Both the casing and the incoming and outgoing lines of the box transformer need to be equipped with specialized lightning protection devices. In addition, additional power lightning protection devices need to be installed at important power distribution entrances. In summer, the lightning protection devices need to be inspected and tested to ensure their normal protective effect, further ensuring the safe operation of the box transformer casing.

2. Pay attention to moisture and rain prevention.

I just mentioned that there is a lot of rain in summer, so when rainy weather approaches, it is necessary to promptly check and ensure the waterproof and sealing performance of the box transformer casing, ensure that the inside of the box transformer casing cannot enter water or be damp, and avoid safety hazards caused by water flowing into the box.

3. Pay attention to heat dissipation.

Due to the hot summer temperature and the long-term operation of the box transformer, it is necessary to strengthen the insulation and heat dissipation capacity of the box transformer shell. The allowable temperature for the operating environment of power transformers is specified, and the high temperature of the transformer environment does not exceed 40 ℃. Excessive temperature can easily cause electrical equipment failures.

4. Avoid overload operation.

Overloading can easily cause frequent faults in the box transformer. Without special circumstances, do not keep the equipment in an overloaded state for a long time. In addition, if the temperature of the box transformer is too high, it is mostly caused by overload operation. It is necessary to reduce the load operation in a timely manner.

Summer is a season of high temperature and humidity, which is very unfriendly to the operating conditions of electrical equipment. However, box transformers are the core part of the entire power system, and even in temporary power projects, box transformers are indispensable. In order to ensure the safety of box transformer power supply and distribution, maintenance work for box transformers should not be slack in any case.
