1. Do a good job of insulation according to the environment

Generally, the required temperature range of high and low voltage switchgear is -10 ℃ -45 ℃. If the ambient temperature is too high, the conductivity of metal parts will become low, while the resistivity will become larger, and the oxidation will gradually accelerate, which will also reduce the insulation strength of insulating parts. Of course, too cold environment will also cause greater internal stress in equipment parts, thus damaging the reliability of insulation parts. Therefore, it is necessary to add some strengthened insulation electrical appliances and insulation protection measures according to the situation, and the surrounding environment requires no fire source, no pollution, no corrosive chemicals.

2. Do a good job in dust prevention and inspection

In order to prevent rust and corrosion, the metal equipment used on the high and low voltage switchgear can be coated with appropriate paint. In order to eliminate the impact of dust on the insulation performance, the dust in the equipment should also be cleaned regularly with a brush. For the electric switch that is often operated daily, the looseness of its fixing screws should be checked regularly, and the lubrication and fastening work should be done well.

3. The internal wiring of high and low voltage switchgear shall be reasonable

Sometimes, due to production needs, it is necessary to temporarily connect and lead out the power supply from the switchgear for the use of high-voltage equipment. When wiring, it is necessary to strictly follow the electrical safety management regulations. Guizhou high and low voltage switchgear adopts wires with good insulation performance, whose safety should fully meet the needs of electrical loads, so that electrical professionals can operate. It is required that the wiring should be smooth without knots, and there should be no intertwining between wires, Do a good job of reliable grounding. When the temporary power supply is not needed, the newly added power supply facilities need to be removed and the site cleaned in time.
