In order to prevent the accident, the manufacturer of the Ready Board needs the personnel on duty in the distribution room to regularly check the safety of the distribution cabinet. What items do you need to check? Today, I'd like to introduce to you what safety inspections need to be done for low-voltage distribution cabinet. Whether the fixing screws at the connecting parts of the main circuit (copper busbar), shunt knife switch and circuit breaker correspond to the indication of the instrument.

Whether the connection points of all parts in the output line are overheated and discolored. During operation, check whether the three-phase load is balanced and whether the three-phase voltage is the same, and check whether the load voltage drop in the workshop exceeds the regulations: whether there is abnormal sound and peculiar smell inside each distribution cabinet and electrical appliance; Whether the circuit breaker with arc extinguishing cover and three-phase arc extinguishing cover are complete; Check whether the circuit breaker and electromagnet core are normally engaged, and whether the wireless coil is overheated or noisy.

Whether the bus insulation clamp of the manufacturer of the Ready Board is damaged and skewed, and whether the fixing screw of the bus clamp is loose; Whether the surface of electrical appliances in the distribution cabinet is clean and whether the grounding connection is normal and good; Whether the doors and windows of the distribution room are intact, whether the door of the distribution cabinet is complete, and whether there is water leakage on the roof in rainy days.

Safety is above all else, so we should take precautions. Nip potential safety hazards in the bud. The lines in the lighting Ready Board are crossed and disordered and not bound into bundles. Consequence: the wiring in the lighting Ready Board is messy, and the two-layer plate in the box presses the pipe orifice tightly, which affects the wire entering the box. If it is squeezed in reluctantly, the insulation of the wire will be damaged for a long time, which is easy to cause short circuit.

The manufacturer of the Ready Board makes the maintenance inconvenient and affects the appearance. Measures: when metal boxes are used for lighting Ready Boards, anti rust and anti-corrosion treatment shall be carried out. The outlet hole in the box can not be opened by electrical welding. One hole shall be made for one pipe, and the protective suit shall be put on the metal box hole before threading..
