A protection inverter suitable for new energy main power supply

Abstract

The invention discloses a protection type frequency converter suitable for new energy main power supply, belonging to the field of frequency converters. The access plug, the left end of the access plug is fixedly connected with the access protection shell located inside the inverter body, the left inner wall of the access protection shell is fixedly connected with the temperature-sensing heat collector, and the access protection shell is fixedly connected with the temperature-sensing heat collector. The temperature-sensing magnetic variable magnetic block on the right side of the chip can be matched with the temperature-sensing heat collector, the temperature-sensing magnetic variable magnetic block, the electrical stability induction component and the fan-type access protection component. The temperature change of the inverter generates induction action, which effectively assists the inverter body to judge the voltage status of the main power supply, improves the functionality and intelligence of the inverter body, effectively reduces the failure rate of various electrical components on the circuit, and promotes new energy. development of.

Description

technical field [0001] The invention relates to the field of frequency converters, and more particularly, to a protection type frequency converter suitable for new energy main power sources. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit and micro-processing unit. The inverter adjusts the voltage and frequency of the output power supply by switching on and off the internal IGBT. In addition, the inverter has many protection functions, such as overcurrent, overvoltage, overload protection and so on. [0003] With the development of society and science and technology, human beings continue to increase the consumption of non-livable resources on the earth...
