Abstract
The invention relates to a method for removing old oil and oil sludge in a transformer, which is used for removing old oil and oil sludge in the transformer during replacement of transformer oil in a large-sized electric transformer. The method for removing old oil and oil sludge in the transformer is reliable, complete flushing is realized, and old oil is replaced completely. The dielectric loss is small after replacement of oil in the transformer, the pre-service standard of super-high-pressure oil is reached, the stability is ensured, and rebounding is prevented. Therefore, residual deteriorated oil molecules in the transformed oil are removed, and various indexes reach the national standard after oil replacement. A large amount of production cost can be saved for an enterprise, and energy is saved for the country.
Description
Technical field
The present invention relates to a kind of to carry out in electric power high-power transformer transformer oil change time, the sweep-out method of waste and old oil and greasy filth in a kind of transformer that the waste and old oil in transformer and greasy filth are removed.
Background technology
In recent years due to produce transformer oil producer especially transformers imported oil producer stop production, present market has bought the makeup oil less than same model, make many transformer oil especially transformers imported oil, in use for some time, due to the deterioration of transformer oil, need the state's produce oil renewing model.Current domestic many power supply units can only filter and remove Residual oil by carry out circulating vacuum after changing to fresh oil again the method for changing oil of the transformer oil of deterioration.So not only expend time in, and thoroughly can not remove original residual deteriorated oil component, in deteriorated Residual oil, have a small amount of active group continuing to play a part to activate deteriorated chemical reaction, deteriorated index bounce-back in a short time after often causing transformer oil to be changed oil.
Summary of the invention
Object of the present invention, a kind of energy method will be provided exactly reliable, and shower puts in place, old oil displacement thoroughly, residual deteriorated oil molecule can be removed in transformer, transformer change oil after dielectric loss little, the sweep-out method of waste and old oil and greasy filth in a kind of transformer that after changing oil, indices is all up to state standards.Technical solution of the present invention is such; A sweep-out method for waste and old oil and greasy filth in transformer, it is characterized in that carrying out according to the following steps;
A when relative air humidity is less than 70%, the waste and old oil in emptying transformer;
B fresh oil is heated to 60 ~ 70 DEG C, and from transformer top manhole, sprayed by oil on transformer body and fuel tank internal wall, circulation flushing three times, the oil after circulation flushing is finally discharged;
C opens low-pressure side manhole, manually enters, and thoroughly removes the waste and old oil in transformer and on chassis and greasy filth;
D vacuum fills fresh oil;
Fresh oil in transformer is extracted out by e vacuum oil-filter, is heated to 50-60 DEG C, after adsorption tanks carry out filtering and adsorb, feeds back in transformer, makes the medium consumption factor of the fresh oil in transformer drop to less than 0.2%.
Use this method to carry out waste and old oil and greasy filth in removing transformer, method is reliable, and shower puts in place, and old oil displacement thoroughly.Transformer change oil after dielectric loss little, meet super high pressure oil put into operation before standard, stable not rebound.Thus deteriorated oil molecule residual in removing transformer oil, after changing oil, indices is all up to state standards.Adopt adsorbent to be the adsorbent reducing medium consumption factor, its production technology is simple, and raw material sources are extensive, low production cost, does not have environmental pollution, and the effective of dielectric loss falls in process transformer oil, rate of finished products is high, can be enterprise and saves a large amount of producing cost, is national energy savings.
