Abstract

The invention provides a frequency converter with an explosion-proof function. The frequency converter comprises a cabinet body and a modular assembly arranged in the cabinet body, the cabinet body comprises an outer cabinet body and an inner cabinet body, and each of the outer cabinet body and the inner cabinet body comprises a side plate. The outer cabinet body and the inner cabinet body share abottom plate and a top plate, a damping device is arranged in a gap formed between the bottom plate of the outer cabinet body and the side plate of the inner cabinet body, and explosion-proof layersare arranged on the outer surface of the inner cabinet body and the inner surface of the outer cabinet body. According to the frequency converter, the outer cabinet body is arranged, the outer cabinetbody and the inner cabinet body are both coated with the explosion-proof layers, and the damping device is arranged, so that the explosion-proof characteristic can be provided.

Description

technical field [0001] The invention relates to the field of frequency converters, in particular to a frequency converter with an explosion-proof function. 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. With the continuous improvement of industrial automation, frequency converters have also been widely used. The inverter may explode during use. There are two main reasons for the explosion. Most of the explosions are caused by external or internal short-circuits, resulting in instantaneous or long-term overvoltage and overcurrent, overloading the module or capacitor, and explosion due to heat swelling; a few are due to device Quality problems or natural aging, power performance decline. Once the frequency converter explodes, it will affect other normal equipment, causing heavy proper...
