The invention discloses a heat dissipation device of a low-pressure chamber of a box-type transformer. The device comprises an outer shell, an air-air heat exchanger, a heat dissipation fan, a circulation fan and an automatic control module, the air-air heat exchanger, the heat dissipation fan, the circulation fan and the automatic control module are arranged in the outer shell, the air-air heat exchanger is provided with an air inlet and an air returning opening, the heat dissipation fan is arranged on the lower portion of the air-air heat exchanger and is connected with cooling fins of the air-air heat exchanger, the circulation fan is arranged in the air inlet or the air returning opening of the air-air heat exchanger, the automatic control module is arranged on the upper portion of the air-air heat exchanger, and when the measured internal temperature of the air-air heat exchanger is higher than the set threshold value, the heat dissipation fan is controlled to be started. The device can ensure that full heat dissipation is performed on the low-pressure chamber, meanwhile, pollutants in external air cannot be introduced in the interior of the low-pressure chamber of the box-type transformer, and the noise of the box-type transformer cannot be leaked outwards, and running reliability of the box-type transformer in the high-temperature environment in summer can be effectively improved.
Description
technical field [0001] The invention relates to a power auxiliary device, in particular to a heat dissipation device for a low-voltage chamber of a box-type transformer. Background technique [0002] Box-type transformers (referred to as "box-type transformers") and other types of power transformation and distribution combined electrical appliances are increasingly used, especially European-type box-type transformers. The internal components are reasonably arranged, and the maintenance and operation are convenient. The fan cools and dissipates heat. However, the low-voltage switch room of the European-style box-type transformer often has poor heat dissipation. Especially in summer, the temperature of the low-voltage switch room often reaches more than 80 °C under the action of the heat of the transformer and the sun, which is far more than the plastic case circuit breaker and other equipment. The allowable ambient temperature limit not only leads to accelerated aging of int...
