Cleaning power equipment, there is a trick for power supply employees!

During the peak of electricity in summer, it is essential to keep electric equipment healthy and safe and efficiently operating safely and efficiently.

That is, "take a bath" for the equipment!

The reason why electric equipment is "bath" is mainly because it is afraid of dirty.

As an important node of the power grid, the substation plays a key role in the reliable operation of the power system. The power equipment of the open -air substation is exposed in the air for a long time, and the surface of the device is prone to filth, and sometimes it will affect the safe operation of the power grid.

Therefore, the operation and maintenance personnel of the substation must "take a bath" for the power equipment in a timely manner.

As we all know, the electric energy is transmitted through water. Why can the power equipment be charged "bath"? There are a lot of attention!

The purity of water is particular

The reason why we can conduct electricity in common seawater, river water, lake water, tap water, etc. in our lives is because they all contain impurities. The water with electricity and flushing power equipment is filtered by industrial, and the resistivity is not less than 100000Ω (Om) · CM (centimeter). As long as the water is pure, it will not conduct electricity.

The rinse distance is particular

When the power supply employees are rinsed with a water -to -strip equipment with water, a certain distance is required between the water spraying mouth and the charging body. The length of the water column should be adjusted according to the diameter of the spray port and the equipment voltage level.

The sequence and angle of the flush are exquisite

When carrying out the "rinse of electric water", the power supply employee will determine the order and angle of the rinse in accordance with the characteristics of different equipment.

For example, when the insulator string, the sewage flows down the insulator. Mixing the filth and water will become a liquid conductive body. When cleaning the insulator string, it should be from the bottom. In addition, if you do n’t pay attention to rinse, water splashing on the equipment will also affect equipment operation and employee personal safety.

Water pressure, the number of nozzles is particular

The number of nozzles, water pressure, etc. of "Rinse Water Rinse" also clearly required. Scientifically use the flushing tool to prevent water rinse flicker accidents.

The weather and the environment are particular

Washing power equipment with water is high in the weather and needs to be carried out when the weather is fine. The wind is too large, the temperature is too low, it is too low, it rains, snowing, shaving sandstorms, and fog or thunder weather should not be "bath".

Of course, not all power equipment can be washed with electricity. All conductive metals, such as lines, transformers, and knife brake mouths cannot be cleaned with water. It is also necessary to prevent water from entering the terminal boxes elsewhere to avoid secondary wiring. The terminal row of the outdoor terminal box, the protection of the screen terminal, the wiring and other equipment should be cleaned with a special cleaner.

Now, in addition to pure water cleaning, you can also use high molecular water, dry ice and other clean power equipment.

Power supply employees use dry ice to clean 110 kV equipment at 220 kV pilling bridge transformer stations.

As a guardian for power equipment, power supply employees need to take care of these equipment carefully and keep them healthy. In addition to "bathing" the equipment regularly, daily cleaning and maintenance are also indispensable.
