High-voltage inverter capable of alarming and self-extinguishing

Abstract

The invention discloses a high-voltage inverter capable of alarming and self-extinguishing. The high-voltage inverter comprises a high-voltage inverter body, a base, a support base, an iron core transformer, a control box and a power unit, wherein the iron core transformer is arranged in the high-voltage inverter body; the control box is arranged in the high-voltage inverter body; the power unit is arranged in the high-voltage inverter body; the support base is arranged on the base; the high-voltage inverter body is arranged on the support base; a vertical separating plate is arranged in the high-voltage inverter body; three horizontal separating plates are arranged in the high-voltage inverter body on the left side of the vertical separating plate; the control box is arranged on the right side of the vertical separating plate; the power unit is arranged on the three horizontal separating plates; the iron core transformer is arranged at the bottom in the high-voltage inverter body; a through hole is formed on the support base; a radiating fan is arranged on the high-voltage inverter body. The high-voltage inverter has the advantages of simple structure, convenience in use and mounting, simple operation, low cost, convenience in wiring, good radiating effect, labor-saving effect, wide application scope, long service life, safety and reliability.

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
