Abstract

The invention discloses an oil temperature circulating oil pump suitable for a transformer oil tank of a substation, comprising an oil temperature detection sensor, a control module, a submersible oil pump, a battery and a solar panel; the control module obtains the main transformer oil tank through the oil temperature detection sensor and the control module presets a threshold oil temperature; and when the oil temperature detection sensor detects that the oil tank temperature is higher than the threshold oil temperature, it controls the submersible pump to speed up the operation; the solar panel and the The storage battery is electrically connected and charged; the storage battery supplies power to the control module, the oil temperature detection sensor and the submersible oil pump. The invention provides an oil temperature circulating oil pump suitable for the main transformer oil tank, which can maximize the performance of the submersible oil pump, so that the submersible oil pump can adjust the operation speed according to the oil temperature in the oil tank, and reduce the maintenance period and maintenance cost.

Description

technical field [0001] The invention relates to the structural field of substation oil pumps, in particular to an oil temperature circulating oil pump suitable for main transformer oil tanks. Background technique [0002] The main transformer of the substation will generate a lot of heat during the working process, so the winding and iron core of the main transformer are immersed in the oil tank for heat dissipation and cooling. With the increase of the working time of the main transformer, the oil temperature near the winding and iron core of the main transformer will only rely on the natural circulation of the temperature difference of the oil flow in the oil tank, which will affect the heat dissipation effect, so it is necessary to add an oil pump to the oil tank to strengthen the oil flow in the oil tank cycle. The resulting strong circulation heat dissipation effect is far better than the natural circulation of temperature difference. [0003] In the process of strong...
