Problems solved by technology

[0003] Cabinet-type inverters are generally medium and high-voltage high-power inverters. In special occasions such as oil fields and mines, sometimes it may be necessary to use the inverter in the open air. The existing cabinet-type inverters are not suitable for use in the open air and need to be improved.

Abstract

The invention discloses a cabinet type frequency converter. The cabinet type frequency converter comprises a frequency converter cabinet body and a power unit which is arranged inside the frequency converter cabinet body, wherein at least one air inlet is formed in the lower portion of the frequency converter cabinet body, at least one draught fan unit is arranged on the top of the frequency converter cabinet body, two bilaterally symmetrical stretchy rods are arranged on the top of the frequency converter cabinet body, a top cover is arranged at the top ends of the two stretchy rods, the draught fan unit is located between the top cover and the two stretchy rods, and a side edge cover is arranged on the outer side of the air inlet. The cabinet type frequency converter has the advantages that the structure is simple and reasonable, a good rainproof function is achieved, and requirements of industrial production are fully met. The cabinet type frequency converter is suitable for being used out of doors.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a cabinet-type frequency converter. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. [0003] Cabinet-type inverters are generally medium and high-voltage high-power inverters. In special occasions such as oil fields and mines, sometimes it may be necessary to use the inverter in the open air. The existing cabinet-type inverters are not suitable for use in the open air and need to be improved. . Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a cabinet-type frequency converter, which has a simple and reasonable structure, has a good rain-shielding function, is suitable for use in the open air, and fully meets t...
