Abstract
A container type variable-frequency drive skid includes a container body, wherein a containing space is provided in the container body, a wiring unit, a voltage transformation unit and a frequency conversion unit are arranged in the containing space, a first cooling unit and a second cooling unit are further arranged in the containing space, the first cooling unit comprises an air duct and a first heat dissipation fan arranged in the air duct, the voltage transformation unit is located in the air duct, air flows through the air duct under the action of the first heat dissipation fan to cool the voltage transformation unit, the second cooling unit comprises a cold guide assembly and a second heat dissipation fan, and the cold guide assembly abuts against the frequency conversion unit. The first cooling unit cools the voltage transformation unit in an air-cooling manner, and the second cooling unit cools the frequency conversion unit in an air cooling and water-cooling combined manner, such that the situation that the voltage transformation unit and the frequency conversion unit cannot operate normally due to too high a temperature is avoided, and the operation efficiency and reliabi…
