The use of high and low voltage distribution cabinet is very important, we should take seriously. Good maintenance in the later period can not only increase its service life, but also save cost for itself. Why not do it? So if the high and low voltage distribution cabinet wants to use for a long time, it should be maintained regularly, but how should it be maintained and maintained?

1. Disconnect the power supply, check whether the rack of the distribution cabinet has reliable grounding, and make the grounding resistance not more than 4 Ω。 2. There are different voltage on the distribution cabinet. The circuit must be distinguished during maintenance to prevent short circuit accidents.

3. All electrical switches on the distribution cabinet shall be flexible and reliable without significant noise. The connection wire junction and terminal shall be free of looseness, and the wire at the connection end of the movable contact shall be free of fracture.

4. Remove dust from panel plug-in and all electromagnetic switch parts with soft brush or blow dryer, and check the status, contact condition, insulation of coil appearance and reliable action of mechanical parts in the distribution cabinet.

5. When replacing the fuse, the fuse current shall match the current of the circuit.

It can effectively reduce the cost by strengthening the service life of the high and low voltage distribution cabinet. Many people know that the increase of life span can reduce certain costs for manufacturers. So, how to extend the service life of high and low voltage distribution cabinet? For a product, if there is no careful care, its service life is reduced, which is not to be questioned. The service life of high and low voltage distribution cabinet is extremely good, that is, careful maintenance in the later period.
