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

Abstract

The invention discloses a high-voltage frequency converter. The high-voltage frequency converter comprises a high-voltage frequency converter main body, a base and a support seat, as well as an iron core transformer, a control cabinet and power units, which are all arranged in the high-voltage frequency converter main body, wherein the support seat is mounted on the base; the high-voltage frequency converter main body is mounted on the support seat; a vertical partition board is arranged in the high-voltage frequency converter main body; three transverse partition boards are arranged in the high-voltage frequency converter main body on the left side of the vertical partition board; the control cabinet is mounted on the right side of the vertical partition board; the power units are mounted on the three transverse partition boards; the iron core transformer is mounted at the inner bottom of the high-voltage frequency converter main body; through holes are formed in the support seat; a cooling fan is arranged on the high-voltage frequency converter main body. The high-voltage frequency converter is simple in structure, convenient to use and mount, simple to operate, low in cost, convenient for wiring, good in radiating effect, wide in application range and long in service life, saves labor and is safe and reliable.

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 P...
