Low Voltage Switchgear

1. Do insulation work according to the environment:

Generally, the temperature range required for high and low voltage switchgear is between -10 °C and 45 °C. If the ambient temperature is too high, the electrical conductivity of the metal parts will be low, and the electrical resistivity will increase, and the oxidation will gradually increase. The insulation strength of the insulating member is also lowered. Of course, an environment that is too cold will also cause large internal stresses on the components of the device, thereby damaging the reliability of the insulation. Therefore, it is necessary to add some reinforced insulation appliances and insulation protection measures according to the situation, and the surrounding environment requires no fire source, no pollution, no corrosive chemicals.

2. Do the appropriate dust prevention and inspection:

Metal equipment used in high and low voltage switchgear can be coated with suitable paints in order to prevent rust and corrosion. In order to eliminate the influence of dust on the insulation performance, the dust in the equipment should be cleaned regularly with a brush. For the operation of the electric gate, it is necessary to regularly check the looseness of the fixing screws and do the lubrication and fastening work.

3. The internal wiring of the high and low voltage switchgear should be reasonable:

Sometimes, due to production needs, it is necessary to temporarily electrify power from the switchgear for high-voltage equipment. In wiring, it must be in strict accordance with the electrical safety management regulations, and the conductors with good insulation performance should be able to fully meet the needs of the power load. Let the electrical professional operate, require the wiring to be smooth and not knotted, and there is no mutual entanglement between the wires and the wires, and a reliable grounding work is done. When the temporary power supply is not needed, it is necessary to promptly remove the newly added power supply facilities and clean the site.
