Description

Technical Field

[0001] The utility model relates to the technical field of industrial production, in particular to a three-proof fully enclosed frequency converter. Background Art

[0002] The frequency converter is an electric energy control device that converts the industrial frequency power supply into another frequency by using the on-off function of the power semiconductor device. With the rapid development of modern power electronics technology and microelectronics technology, high-voltage and high-power frequency conversion speed regulation devices have continued to mature. The high-voltage problem that has been difficult to solve has been well solved in recent years through the series connection of devices or units. The device that converts AC power with fixed voltage and frequency into AC power with variable voltage or frequency is called a "frequency converter". The equipment must first convert three-phase or single-phase AC power into DC power, and then convert DC power into three-phase or single-phase AC power.

[0003] In order to enhance the heat dissipation effect, ordinary inverters have multiple heat dissipation holes. The existence of the heat dissipation holes will cause water and dust to enter the inverter through the heat dissipation holes of the inverter casing and damage its internal circuits, limiting the installation conditions of the inverter. Fully enclosed inverters will cancel the opening of heat dissipation holes and replace them with a heat sink to dissipate heat, which can prevent dust from entering. However, dust is easily accumulated in the gaps of the heat sink, which will seriously reduce the heat dissipation effect of the heat sink in the long run. Therefore, a three-proof fully enclosed inverter with stable heat dissipation is needed. Utility Model Content
