High voltage inverter capable of automatically extinguishing fire

Abstract

The invention discloses a high voltage inverter capable of automatically extinguishing fire comprising a high voltage inverter body, a base, a supporting seat, an iron core transformer arranged in the high voltage inverter body, a control box arranged in the high voltage inverter body and a power unit arranged in the high voltage inverter body, wherein the supporting seat is installed on the base, the high voltage inverter body is installed on the supporting seat, a vertical division plate is arranged in the high voltage inverter body, three transverse division plates are arranged in the high voltage inverter body on a left side of the vertical division plate, the control box is installed on a right side of the vertical division plate, the power unit is installed on the three transverse division plates, the iron core transformer is installed at the bottom in the high voltage inverter body, a through hole is formed in the supporting seat, and a heat dissipating draught fan is arranged on the high voltage inverter body. The high voltage inverter is simple in structure, convenient to use and install, simple to operate, low in cost, convenient for wiring, good in heat dissipating effect, labor-saving, wide in application range, long in service life, 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 Publ...

AI Technical Summary

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
