Abstract

The invention discloses a high-voltage frequency converter with a safety protection structure and a working method thereof. The converter comprises a protection box, wherein a damping support is installed in the center of an inner wall of the bottom of the protection box, a high-voltage frequency converter body is installed at the center of the top of the damping support, a lower sliding groove isformed in one side of the bottom of the protection box, a reciprocating screw rod is rotatably connected with the interior of the lower sliding groove, a gear motor in driving connection with the reciprocating lead screw is installed on one side of the bottom of the protection box, a sliding block sliding in the lower sliding groove is connected with the reciprocating lead screw in an engaged mode, the sliding block is fixed to the corner of one side of the bottom of the box door, and an electronic lock is installed in the center of one side of the protection box. The high-voltage frequency converter is novel in structure and ingenious in conception, accidental electric shock of workers can be prevented, the workers can be prevented from conducting maintenance work in an electrified stateof the high-voltage frequency converter body, and use safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage frequency converters, in particular to a high-voltage frequency converter with a safety protection structure and a working method thereof. Background technique [0002] The frequency converter is a power control device that uses the on-off function of power semiconductor devices to convert the power frequency power supply to another frequency. With the rapid development of modern power electronics technology and microelectronics technology, high-voltage and high-power frequency conversion speed control devices continue to mature. The high-voltage problem that has been difficult to solve has been well solved in recent years by connecting devices or units in series. High-voltage and high-power frequency conversion speed control devices are widely used in various fans, water pumps, compressors, rolling mills, etc. [0003] The existing high-voltage inverters need to be powered off manually duri...
