The invention discloses an automatic temperature control method of a prefabricated cabin transformer substation. The automatic temperature control method of the prefabricated cabin transformer substation comprises the following steps: when a temperature controller detects that the temperature value of the prefabricated cabin is less than a set value T0, opening electric control air valves on a first ventilation opening and a second ventilation opening, and closing electric control air valves on an air outlet, an air inlet and an auxiliary air opening; when the temperature controller detects that the temperature value of the prefabricated cabin is greater than the set value T0, opening the electric control air valves on the second ventilation opening, the air outlet and the auxiliary air opening, and closing the electric control valves on the first ventilation opening and the air inlet; when the temperature controller detects that the temperature value of the prefabricated cabin is equal to the set value T0, opening the electric control valves on the air inlet and the air outlet, and closing the electric control air valves on the first ventilation opening, the second ventilation opening and the auxiliary air opening. The mounting cost and the operation energy consumption of the prefabricated cabin transformer substation are reduced, and the heat-insulating property is improved.
Description
technical field [0001] The invention relates to the technical field of substations, in particular to an automatic temperature control method for a prefabricated cabin substation. Background technique [0002] At present, with the increasing shortage of urban land, prefabricated cabin substations with compact structure and small volume are widely used. The prefabricated cabin is generally made of splicing steel plates on the support frame, and the electrical equipment in the prefabricated cabin substation is placed in the prefabricated cabin, and the temperature in the prefabricated cabin has a great influence on the operation of the electrical equipment. Chinese Patent No. 201511010966.4 discloses a prefabricated cabin-type substation and a heat dissipation control method. By forming a through air channel in the bottom foundation of the prefabricated cabin, heat dissipation is realized by using the height difference and the temperature difference between the foundation and t...
