Antioxidant adding apparatus

Abstract

The invention relates to a device for adding an antioxidant and belongs to equipment for adding, heating and stirring the antioxidant and carrying out on-line oil charging to electric power equipment. The device comprises an automatic control system; the upper part of a buffering oil storage tank is communicated with a vacuum pump by a pipeline; the bottom of the buffering oil storage tank is connected with an oil delivery pump and an oil delivery electromagnetic valve by pipelines in sequence and communicated with an oil inlet of the upper part of a stirring tank; an oil outlet of the bottomof the stirring tank is connected with a circulation electromagnetic valve and a heater by pipelines in sequence and communicated with an oil inlet of the top of a buffering circulation tank; an inlet of the heater is connected with an oil inlet pipeline; an oil inlet electromagnetic valve is arranged on the oil inlet pipeline; an outlet of the oil delivery pump is connected with a pair of external oil charging pipelines which is provided with oil exhaust electromagnetic valves; and a feed port for adding the antioxidant and a release valve are arranged on the stirring tank. The device has the characteristics of high automation degree, sensitive and reliable control and easy operation.

Description

technical field [0001] The invention relates to a refueling device for adding materials to circulating oil, in particular to an oil circulating feeding processing device for refueling oil-filled power equipment under pressure after adding antioxidants to the oil, heating and stirring. Background technique [0002] Turbine oil or transformer oil needs to add T501 antioxidant, and there is no mature method for adding antioxidant, especially online addition. In the past, it was only possible to use a larger container to heat and dissolve the solid antioxidant after power failure or shutdown, and then add it to the equipment through the oil filter. The premise of this addition method is that there must be a large solvent to dissolve the antioxidant, and at the same time, an additional temperature-controllable heating device is required to realize the dissolution of the antioxidant. This process is feasible if a small amount of addition is required, but it is necessary to add a ...

Problems solved by technology

The premise of this addition method is that there must be a large solvent to dissolve the antioxidant, and at the same time, an additional temperature-controllable heating device is required to realize the dissolution of the antioxidant. This process is feasible if a small amount is added, but it is necessary to add a large amount. (For example, the additional amount is 100 kg), the on-site operation is more difficult, which is also an important reason why some equipment should be added but not added in time

At the same time, using the old method is also difficult to achieve online replenishment without power failure or shutdown

This artificial filling method is time-consuming, laborious and inefficient
