High and low voltage switchgear installation precautions

What are the precautions when using high and low voltage power distribution cabinets?

Insulation work should be done well. Generally, the temperature range required for high and low voltage power distribution cabinets 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 Accelerating will also reduce the insulation strength of the insulating member.

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, Xiangtai adds some reinforced insulation appliances according to the situation, and insulation protection measures are necessary, and the surrounding environment requires no fire source, no pollution, no corrosive chemicals.

Do dustproof work regularly. Metal equipment used in high and low voltage switchgear equipment 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 circuit breakers that are frequently operated daily, the looseness of the fixing screws should be checked regularly to do the fastening work.

The internal wiring of high and low voltage power distribution cabinets must be reasonable. Sometimes, due to production needs, it is necessary to connect the temporary power supply from the switchgear for high-voltage equipment. In the wiring, it is necessary to strictly follow the electrical safety management regulations, and adopt the wire with good insulation performance. The safety should fully meet the needs of the power load. The electrical professional performs the operation, and the wiring is required to be smooth and not knotted. There is no mutual entanglement between the wires and the wires, and a reliable grounding work is performed. When the temporary power supply is not needed, it is necessary to promptly remove the newly added power supply facilities and clean the site.
