A variable-frequency power supply with a dustproof structure disclosed by the invention comprises a cabinet body, a protection shell and a mounting shell, wherein a variable-frequency power supply body is placed in the cabinet body, a first ventilation opening, an exhaust opening and a second ventilation opening are respectively formed in the tops and the bottom parts of the two sides of the cabinet body and the top part of the back surface of the cabinet body, a dustproof net cover and a silica gel adsorption filter screen plate which are used in cooperation with each other are fixedly installed in each of the first ventilation opening, the exhaust opening and the second ventilation opening in sequence, a sealing door is slidably installed in the installation block through a sliding block, a first bottle liner, a second bottle liner and an installation cavity are arranged in the protection shell, a refrigeration sheet is fixedly installed on the back face of the interior of the installation shell, and a fan is fixedly installed on the front face of the refrigeration sheet. Through the cabinet body, the sealing door, the dustproof net covers and the silica gel adsorption filter screen plates, the variable-frequency power supply can perform dustproof operation, and the practicability of the variable-frequency power supply is improved.
Description
technical field [0001] The invention relates to the technical field of variable frequency power supplies, in particular to a variable frequency power supply with a dustproof structure. 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 frequency converter is mainly composed of rectification, filtering, inverter, braking unit, drive unit, and detection unit. and other components, the frequency converter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter has many Protection functions, such as overcurrent, overvoltage, overload protection, etc., wit...
