Abstract

The invention discloses a high-voltage frequency converter with a safety protection structure and a working method thereof. The main body of the high-voltage frequency converter, the bottom side of the protective box is provided with a glide groove, the inside of the glide groove is connected with a reciprocating screw rod for rotation, and the bottom side of the protective box is equipped with a geared motor connected to the reciprocating screw rod , the reciprocating screw rod is meshed with a slider that slides inside the chute, the slider is fixed at the corner of the bottom side of the door, and an electronic lock is installed at the center of one side of the protective box. The invention has a novel structure and an ingenious concept, which can not only prevent workers from accidental electric shock, but also prevent workers from performing maintenance work while the high-voltage frequency converter body is charged, thereby greatly improving the safety of use.

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...
