Abstract

The invention discloses a container type frequency conversion pry. The pry comprises a box body, an accommodating space is formed in the box body; a wiring unit, a voltage transformation unit and a frequency conversion unit are arranged in the accommodating space; a first cooling unit and a second cooling unit are also arranged in the accommodating 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 dissipationfan to cool the voltage transformation unit, the second cooling unit comprises a cold conduction assembly and a second heat dissipation fan, and the cold conduction assembly abuts against the frequency conversion unit. The first cooling unit cools the voltage transformation unit in an air cooling mode, the second cooling unit cools the frequency conversion unit in an air cooling and water coolingcombined mode, the situation that the voltage unit and the frequency conversion unit cannot normally operate due to the too high temperature is avoided, and the operation efficiency and reliability ofthe whole machine are improved.

Description

technical field [0001] The invention relates to the technical field of oil, coal bed gas and shale gas drilling and production equipment, in particular to a container-type frequency conversion skid. Background technique [0002] At present, electric drive fracturing pumps have just begun to develop, and the motor drive of fracturing pumps is generally driven by frequency converters. However, the frequency converter is used as the power supply for driving the motor of the fracturing pump. The main problems currently faced are as follows: ordinary frequency converters cannot be directly applied to oilfield workplaces, and even the frequency converters with protective casings have large dimensions, heavy weight, and The power density of the machine is small, and only one frequency converter can drive one fracturing pump motor. [0003] In order to solve the above technical problems, a container-type frequency conversion skid appeared, which integrates components such as variab...
