The structure is simple, the application and installation are convenient, the operation is simple, the cost is low, the wiring is convenient, the heat dissipation effect is good, labor is saved, the application scope is wide, the service life is long, and the safety and reliability are high.

Description

technical field [0001] The invention relates to a high-voltage frequency converter, which belongs to the field of electric power. Background technique [0002] High-voltage frequency converters are now widely used in metallurgy, mining, electric power, petrochemical, cement, water supply and drainage, and central air-conditioning, and many other fields. It has become the first choice for enterprises to adopt energy-saving methods of motor systems. High-voltage frequency converters are generally composed of four separate transformer cabinets, power unit cabinets, control system cabinets and input and output cabinets. At present, many high-voltage inverters on the market consist of many cabinets and occupy a large area. During packaging and transportation, they need to be disassembled and separated into cabinets. When they are installed on site, they need to be assembled and wired, which increases the workload of disassembly and installation. Chinese Utility Model Patent Publ...

Problems solved by technology

[0003] There are many internal circuits in high-voltage inverters, which are very easy to cause fires due to heat, but the current high-voltage inverters lack the function of automatically detecting its internal temperature to determine whether its internal fire is caused by a short circuit and the function of automatic fire extinguishing, so when the high-voltage inverter Failure to extinguish the fire in time after the internal circuit short circuit and heating cause a fire can easily cause a wider range of short circuits in the internal circuit of the high-voltage inverter and cause a wider range of fires, which poses a great safety hazard
