Abstract

The invention discloses an explosion-proof high-voltage frequency converter, which comprises a shell, wherein a monitoring port is formed in the front face of the shell, a fixed grid plate is fixedly connected to the position, located outside the monitoring port, of the front face of the shell, a rubber strip is fixedly connected to the inner surface of the fixed grid plate, a sealing assembly is hinged to one side of the shell through a hinge, the sealing assembly comprises a sealing door, a visible window is formed in one side of the sealing door, and a rubber strip is arranged on the fixed grid plate and matched with a first sealing strip on a transverse strip and a second sealing strip on a vertical strip in the sealing assembly, and a first gear and a second gear on a screwing block are meshed, and the first sealing strips and the second sealing strips on the transverse strips and the vertical strips can tightly press the rubber strips. By adopting the explosion-proof high-voltage frequency converter, methane gas can be prevented from entering the shell, and the situation of explosion is prevented to a certain degree.

Description

technical field [0001] The invention relates to the field of explosion-proof technology, in particular to an explosion-proof high-voltage frequency converter. Background technique [0002] At present, the high-voltage frequency converter has been widely used. The frequency converter is a power control device that uses the on-off function of the power semiconductor device 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. In China, most products adopt the form of series connection of power units. [0003] Current frequency converters basically do not have explosion-proof functions, and high-voltage frequency conversion is also required to work in coal mines containing methane gas. Once a short circuit or leakage occurs in the frequency converter, it is easy to cause an expl...
