Abstract

The invention relates to a mining voltage type high-voltage explosion-proof frequency converter. The mining voltage type high-voltage explosion-proof frequency converter comprises a shell, wherein a plurality of reinforcing ribs are arranged on the outer wall and the inner wall of the shell; a plurality of clapboards are arranged in the shell, and partition the internal space of the space into a primary circuit chamber, a secondary circuit chamber and a water-cooling system chamber. The mining voltage type high-voltage explosion-proof frequency converter further comprises a water-cooling device, wherein the water-cooling device comprises an internal portion and an external portion; the internal portion is arranged in the water-cooling system chamber; the external portion is arranged outside the shell; the internal portion comprises an explosive-proof valve, a water distribution pipe and a water return pipe; the external portion comprises a radiator, an deionization exchanger and a pump unit. The mining voltage type high-voltage explosion-proof frequency converter has the beneficial effects that the explosion prevention problem during application of a voltage type high-voltage frequency converter under a coal mine is solved, and the problem of heat dissipation of a unit type structure is solved successfully. Through a water-cooled matched cabinet which is consistent with an explosion-proof standard, a plurality of water-cooling systems can be used at the same time, and a quick response can be made to failure of a cooling portion.

Description

technical field [0001] The invention relates to a frequency converter, in particular to a mine voltage type high-voltage explosion-proof frequency converter. 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. [0003] At present, high-voltage frequency converters have been widely used. In China, most products adopt the type of series connection of power units. However, this high-voltage frequency converter has no explosion-proof function, so it cannot be used in coal mines containing methane gas. C...
