Abstract

The present invention provides a current transformer heat radiation apparatus comprising a cabinet body, through which cooling wind can pass. The cabinet body is provided with a partition plate in the direction of passing of the cooling wind to separate the inside of the cabinet body into a first chamber in which an electric reactor can be mounted and a second chamber in which a power module can be mounted. The partition plate is connected to the power module in a sealed way. The partition plate is fixedly connected to one end, provided with an air inlet, of the cabinet body. The partition plate is connected to the inner wall of the cabinet body in a sealed way in the direction of the two ends perpendicular to the cooling wind flow direction. The two ends of the first chamber are respectively connected with the air inlet and an air outlet. The partition plate is provided with a vent hole connected with an air transmission duct and the second chamber. Cooling fins of the power module extend into the air transmission duct through the vent hole. The current transformer heat radiation apparatus of the invention has high heat radiation capability and longer heating components usage life.

Description

technical field [0001] The invention belongs to the technical field of converter cooling devices for rail transit, and in particular relates to a converter cooling device. Background technique [0002] The converter has the functions of inverter feedback, rectification and traction, and voltage stabilization. When it is used for ground power supply of urban rail transit, it can realize the conversion between AC and DC in the substation. The main heating components of the converter include self-power modules and reactors. In order to ensure the good performance of each component, it is necessary to dissipate heat from each heating component when the converter is working. [0003] However, the air duct design of the existing converter cooling device is to connect various heating components in series in the entire ventilation direction, so it is difficult to dissipate heat from different heating components separately, resulting in the air temperature gradually increasing along ...
