Abstract
The invention discloses a heat dissipation apparatus of a reactor cabinet body. The apparatus comprises an upper wind shield, a lower wind shield and a heat exchanger. The reactor cabinet body is internally provided with a network-side reactor and a machine-side reactor. When the heat exchanger works, hot air above the network-side reactor in the cabinet body is absorbed by the upper portion of the heat exchanger, and thus power for air cyclic circulation in the cabinet body is formed. After the hot air goes into the heat exchanger, cooling processing is performed, and the cooled air goes into the cabinet body from the lower portion of the heat exchanger. Cold air, under the effect of the lower wind shield, passes from the lower portion of the cabinet body via a gap between the machine-side reactor and the lower wind shield and a solenoid air gap of the machine-side reactor. The cold air, after passing through the machine-side reactor, under the effect of the upper wind shield, passes via a gap between the network-side reactor and the upper wind shield and a solenoid air gap of the network-side reactor, and thus a complete air flow cycle in the cabinet body is formed. The apparatus provided by the invention can effectively improve the ventilation heat dissipation effect of such large-power devices as reactors and the like in a current transformer cabinet body in an economical way.
