Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] A distribution network control cabinet suitable for plateaus, including a cabinet body and a control system arranged in the cabinet body, the control system is divided into three layers: top layer, middle layer and bottom layer, the top layer includes control chips, the middle layer includes power modules, and the bottom layer Including the reactor; the control cabinet also includes the radiator corresponding to the power module.
[0031] Based on the above technical solutions and in conjunction with the accompanying drawings, the following specific implementation is given.
[0032] In order to better adapt to the special climate conditions of the plateau, the present invention provides a distribution network control cabinet suitable for the plateau, such as figure 1 As shown, the control cabinet includes a cabinet body 6 and a control system. The con...

The invention relates to a power distribution network control cabinet applicable to plateaus. The power distribution network control cabinet comprises a cabinet and a control system. The control system is arranged in the cabinet and is divided into a top layer, a middle layer and a base layer, the top layer comprises a control chip, the middle layer comprises a power module, and the base layer comprises an electric reactor. The power distribution network control cabinet has the advantages that the power distribution network control cabinet with the layout is small in occupied volume, low in cost and convenient to maintain in later periods; the power module with high heating value is arranged below the control chip, so that excellent heating and dehumidifying effects can be guaranteed for the control chip, and heating environments of the power module of the middle layer can be guaranteed by the electric reactor of the base layer; a radiator corresponds to the power module with the high heating value, so that excellent radiating effects can be guaranteed for the power module; the radiator is arranged under the middle layer, so that radiating effects can be simultaneously guaranteed for the middle layer and the base layer by the single radiator, the quantities of radiators and radiating fans can be reduced, and the cost can be saved; radiating plates and the base layer are arranged at intervals, so that excellent ventilating effects of the base layer can be guaranteed, and the radiating efficiency can be improved.
Description
technical field [0001] The invention relates to a distribution network control cabinet suitable for plateaus, belonging to the technical fields of smart grid and power electronics. Background technique [0002] Since the plateau operating environment is very different from the ordinary low-altitude environment, it is necessary to carry out special structural treatment according to the environmental characteristics of the plateau to meet the safe and reliable operation of the equipment in the plateau environment. The plateau has harsh natural climate conditions, which have a great impact on the performance of power electronic equipment. The main characteristics of the plateau climate are: [0003] (1) Low air pressure or air density; [0004] (2) The air temperature is low and changes greatly; [0005] (3) The absolute humidity of the air is small; [0006] (4) There are many thunderstorm days; [0007] (5) The solar radiation illuminance (ultraviolet rays) is relatively ...
