Abstract

The invention discloses an oil temperature circulating oil pump applicable to a transformer oil tank of a substation. The oil temperature circulating oil pump comprises an oil temperature detection sensor, a control module, an oil-submerged pump, a storage battery and a solar panel, wherein the control module obtains oil temperature in a main transformer oil tank through the oil temperature detection sensor and is set with an oil temperature threshold in advance; when the oil temperature detection sensor detects that the temperature of the oil tank is higher than the oil temperature threshold,the oil-submerged pump is controlled to increase the running speed; the solar panel is electrically connected with the storage battery and charges the storage battery; and the storage battery provides the control module, the oil temperature detection sensor and the oil-submerged pump with electricity. According to the oil temperature circulating oil pump applicable to the main transformer oil tank, the performance of the oil-submerged pump can be developed to the maximum extent, the running speed of the oil-submerged pump can be adjusted according to the oil temperature in the oil tank, the maintenance cycle is shortened and the maintenance cost is reduced.

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...
