Prefabricated cabin type transformer substation and heat dissipation control method

Abstract

The invention discloses a prefabricated cabin type transformer substation and a heat dissipation control method. The prefabricated cabin type transformer substation comprises a communicated air channel, a first prefabricated cabin, a second prefabricated cabin and a third prefabricated cabin, wherein a transformer main body is arranged in the first prefabricated cabin, a cooling fin is arranged in the second prefabricated cabin and a neutral point disconnecting switch is arranged in the third prefabricated cabin; the neutral point disconnecting switch is connected with the transformer main body through a wire; the communicated air channel is located under the first prefabricated cabin and the third prefabricated cabin, and cabin bottoms of the first prefabricated cabin and the third prefabricated cabin both are provided with a ventilating grate communicated with the connected air channel; the top of the first prefabricated cabin is provided with an exhaust outlet and a temperature sensor, a fan is also arranged in the first prefabricated cabin, the top of the second prefabricated cabin is an open type structure, and side walls of the second prefabricated cabin and the third prefabricated cabin both are provided with a ventilating shutter. Reduction of running noise and energy consumption of the prefabricated cabin type transformer substation is realized.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a prefabricated cabin type substation and a heat dissipation control method. Background technique [0002] At present, with the rapid growth of urban electricity load, building new substations in the center of the city and connecting power from the periphery of the city through high-voltage cables has become an urgent problem facing the power supply of many economically developed cities in my country. However, the current construction of substations generally has the problem of "difficulty in landing", mainly due to the shortage of land resources in various places, and it is difficult to allocate land for substation construction. In addition, the traditional substation is generally a civil construction model, which requires on-site construction and construction, which has the disadvantages of long construction period, great impact on the surrounding environment, and large foo...

AI Technical Summary

Problems solved by technology

However, in the actual use process, the electrical components of the prefabricated cabin type substation are installed in the prefabricated box. In order to meet the heat dissipation requirements, it is usually necessary to be equipped with a high-power cooling fan and a large-sized cooling fin. The noise is relatively large, and the cooling fan will also consume a large amount of electric energy, resulting in relatively high noise and high energy consumption in the prefabricated cabin-type substation in the prior art
