Abstract

The invention discloses an internal circulation ventilation type power distribution cabinet for power distribution automation, and the cabinet comprises a housing which is internally provided with a heat dissipation cavity and a rectangular cavity, and the rectangular cavity is located below the heat dissipation cavity. A circulating heat dissipation mechanism is arranged in the heat dissipation cavity, the circulating heat dissipation mechanism comprises a second hollow strip installed at the top in the heat dissipation cavity, a rotating pipe is rotationally connected to the inner bottom of the heat dissipation cavity, and a first hollow strip is fixedly connected to the upper end of the rotating pipe; a plurality of air openings are formed in the opposite faces of the first hollow strip and the second hollow strip correspondingly, and a circulating fan is installed on the left side of the shell. According to the power distribution cabinet, the internal circulating fan is adopted for heat dissipation, a good heat dissipation effect can be achieved, dust can be prevented from entering the interior of the power distribution cabinet while cooling is effectively carried out, and the interior of the power distribution cabinet can be further cooled due to the arrangement of the semiconductor chilling plate and the touch delay switch.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, in particular to an internal circulation ventilation type power distribution cabinet for power distribution automation. Background technique [0002] The power distribution cabinet is an important equipment in the power distribution automation system. It will generate a lot of heat when it is working. When the heat accumulates too much, it will affect the normal operation of the power distribution cabinet. Therefore, it is necessary to dissipate heat from the power distribution cabinet. Among the existing equipment, Generally, vents are set on the cabinet body for ventilation and heat dissipation, which is a commonly used heat dissipation method for existing power distribution cabinets; [0003] However, in the actual use process, using this method for heat dissipation will bring external dust into the interior of the power distribution cabinet. More dust will easily lead to short-circu...
