Electrical cabinet, also known as electrical control cabinet, is a type of electrical equipment. Outside the electrical cabinet, first enter the main control switch of the cabinet, and then enter the auxiliary control switch. Each subcircuit is configured as needed. One or more low-voltage switchgear and its associated control, measurement, signalling, maintenance, regulating and other equipment are components for which all internal electrical and mechanical connections are made by the manufacturer and fully assembled with structural components.
The main function of the electrical control cabinet is to open, close, control and maintain the electrical equipment in the process of power generation, transmission, distribution and energy conversion. The components in the electric cabinet are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various maintenance devices.
The electrical control cabinet is a cabinet that installs electrical control components such as air switches. Touch display gauges and control buttons. Cabinets for on-site control of electromechanical equipment. The electric control cabinet is made by absorbing the advanced experience of pump control at home and abroad. After years of production and application, it has been continuously improved and optimized, and has been carefully designed and manufactured.
The electrical control cabinet has the functions of overload, short circuit, phase loss maintenance, pump body leakage, motor overtemperature, electric leakage, etc., as well as single-pump and multi-pump control operation forms, various main and standby pump switching methods and various starting methods. It can be widely used in agricultural production and automatic control of water supply, drainage, fire protection, sprinkler pipe network pressure, HVAC, and cold and hot water circulation in various buildings.
All equipment in the transmission cabinet should be properly grounded and connected to a common ground point or ground bus using a stubby ground wire. Any control equipment (such as PLC) connected to the inverter should be grounded with the inverter, and a short and thick wire should be used for grounding. Flat conductors such as metal mesh are favored for their low impedance at high frequencies. Low-voltage installations, relays and electrical cabinet contactors should be protected by fuses. When you don't know the mains grid, it is recommended to add an incoming reactor.
