The high and low voltage distribution cabinet is the key equipment in the power system.High-voltage power distribution cabinets are used to receive and distribute electrical energy. The voltage level is commonly 10kV, etc. There are types of inlet cabinets, outlet cabinets, etc., with circuit breakers, transformers and other components to achieve control, protection and other functions.The low-voltage power distribution cabinet further distributes the electrical energy after the high-voltage is buckled by the transformer, such as 0.4kV voltage, including chest of drawers, fixed cabinets, etc., including circuit breakers, contactors, etc., to ensure the safety and stability of electricity consumption.Its technical points cover insulation performance, protection level, short-circuit tolerance, etc. Reasonable selection, installation and commissioning are of great significance to ensure the reliable operation of the power system, reduce failures and ensure the safety of personnel.
