Today, the editor of Xi'an Senyuan Electric Technology Co., Ltd. will introduce in detail the precautions for daily use and maintenance of high and low voltage distribution cabinets. First, we need to understand what high and low voltage distribution cabinets are and what are the precautions for maintenance?

What is a high and low voltage distribution cabinet?

High and low voltage distribution cabinets usually refer to equipment that connects high or low voltage cables. They are used in power stations, substations, and other facilities. High voltage cabinets are used to reduce voltage through transformers before being connected to a low voltage cabinet, which in turn connects to various electrical distribution boxes. It is actually an electrical equipment that assembles some protective devices such as switches and circuit breakers into one unit.

In order to ensure the normal operation of high and low voltage distribution cabinet equipment, it is necessary to carry out daily maintenance and upkeep of the high and low voltage distribution cabinets.

Here, the editor reminds everyone to do a good job of insulation protection in different environments. Generally, the working temperature range required for high and low voltage distribution cabinets is between -10 ℃ and 45 ℃. If the ambient temperature is too high, it will lower the conductivity of metal components, increase the resistivity, and accelerate the oxidation process, which will also reduce the insulation strength of insulation components. When the weather is too cold, it can also cause significant internal stress in equipment components, thereby damaging the reliability of insulation components. So it is necessary to add some insulation type electrical appliances according to the situation and take good insulation protection measures for the maintenance of high and low voltage distribution cabinets.

Secondly, ensure proper maintenance and dust prevention of high and low voltage distribution cabinets.

Metal equipment used on high and low voltage distribution cabinets can be coated with suitable paint to prevent rust and corrosion. In order to eliminate the impact of dust accumulation on the insulation performance of high and low voltage distribution cabinets, it is also necessary to regularly clean the dust in the equipment with a brush. For frequently operated switches, the looseness of their fixing screws should be checked regularly, and lubrication and fastening work should be done well.

Thirdly, when maintaining high and low voltage distribution cabinets, attention should be paid to the reasonable internal wiring.

When wiring inside the high and low voltage distribution cabinet, it is necessary to strictly follow the electrical safety management regulations, use wires with good insulation performance, and allow electrical professionals to operate. The wiring should be smooth and not tangled, and there should be no entanglement between wires arranged neatly. Reliable grounding work should be done well.
