Common knowledge of low-voltage switchgear

1. Low-voltage switchgear: It is an electrical device mainly based on isolation switches. The point is that the manufacturer uses the relevant convex and concave electricity (including the handling of electrical appliances, maintenance of electrical appliances, measurement of electrical appliances) and their bus ducts, current-carrying conductors, insulation and metal material cabinets in accordance with the main wiring methods of closed or open bodies. of other equipment. It acts as a device for conducting and distributing electromagnetic energy in a power engineering management system.

2. High-voltage power switch equipment: mainly used for power generation, transmission and distribution, power distribution equipment and electromagnetic energy conversion high-voltage power switch and its operation, measurement, maintenance equipment, electrical equipment coordination (busway), casing, etc. collective name.

3. The "five preventions" in the safety protection regulations of low-voltage switchgear: 1. Avoid mis-opening and closing the isolating switch, 2. Avoid inductive electrification dividing and closing the resistance isolation switch, 3. Avoid inductive electrification and grounding device power switch , 4. Avoid opening and closing the isolating switch with grounding device, 5. Avoid entering the induction electrification distance by mistake.
