Description
Technical field
The utility model relates to the transformer technology field, is specifically related to the transformer insulated Decvice for regeneration of oils of a kind of electric power.
Background technology
Transformer, as a kind of main soft magnetism electromagnetic component, is widely used in power technology, and its major function is power transmission, voltage transformation and insulation isolation.In transformer, transformer insulation oil is the important insulation of transformer and coolant, and the quality of transformer oil directly affects the safe and stable operation of transformer.Transformer insulation oil is in long-term running, be subject to the effect of electric field, humidity, temperature, light, oxygen and foreign material, its Chemical Physics performance and dielectric property progressively degenerate and are aging, the result that insulating oil is aging will produce various oxides, moisture, organic acid, methane, the suspended matters such as ethene, acetylene, carbon granules, cause insulating oil variable color, acid number rising flash-point to reduce, dielectric property worsen.The fault of some transformers and accident have direct relation with the quality of transformer oil invariably.Therefore, to transformer insulation oil purified, regenerating is necessary.
Existing transformer insulation oil regeneration techniques is all to adopt closed cycle to filter, transformer oil enters oil filter from the bottom of transformer, transformer oil enters the top of transformer from the oil filter outlet, because transformer oil is mixing in filter process always, oil strain efficiency is lower.Yet the transformer insulated oilreserves of some large power plants is very large, if according to the prior art processing of regenerating, will be one not only time-consuming, effort, efficiency is low but also loaded down with trivial details work.
The utility model content
The purpose of this utility model is to provide a kind of installation, simple and safe operation, and the transformer insulation oil regeneration efficiency is high, the measured transformer insulated Decvice for regeneration of oils of matter.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of transformer insulated Decvice for regeneration of oils, comprise oil storage tank, and oil storage tank is connected in series with vacuum oil-filter and transformer; Oil storage tank is connected with vacuum oil-filter with second pipe by the first pipeline, and the first pipeline is connected in series with second pipe; Vacuum oil-filter is connected with transformer with the 4th pipeline by the 3rd pipeline, and the 3rd pipeline is connected in series with the 4th pipeline; Transformer is connected with second pipe by the 5th pipeline, and oil storage tank is connected with the 4th pipeline by the 6th pipeline; Be respectively arranged with the first control valve, the second control valve, the 3rd control valve, the 4th control valve, the 5th control valve, the 6th control valve on the first pipeline, second pipe, the 3rd pipeline, the 4th pipeline, the 5th pipeline and the 6th pipeline.
Described transformer is connected with a vacuum pump by the 7th pipeline, is provided with the 7th control valve on the 7th pipeline.
Also be provided with a vacuum meter on described transformer.
Described vacuum oil-filter is the two-stage vacuum oil filter.
Described the first control valve, the second control valve, the 3rd control valve, the 4th control valve, the 5th control valve, the 6th control valve are butterfly valve.
The transformer insulated Decvice for regeneration of oils that the utility model provides, improved degassing efficiency on the one hand, realized the regeneration of transformer insulation oil, also has on the other hand dehydration concurrently and drive damp function.In the transformer of high vacuum, at downward " spray " the formation film while coming that disperses of insulating oil, and be sprayed at oil in the device body from the top down in mobile process, the oil meter area increases, fully be exposed to certain hour in vacuum, take off not most gas, moisture, volatile acid etc. through the two-stage vacuum oil filter in insulating oil and extracted out by vacuum pump.In addition, because the heat conductivity of insulating oil is good, thermal capacity is large again, and transformer itself is played to deep fat heat drying effect to a certain extent.
The higher temperature that the utility model creates by the two-stage vacuum oil filter and hypobaric environment, make dissolved gases in transformer insulation oil, moisture be easy to overflow from insulating oil; Change air pressure in transformer by vacuum pump is installed, make insulating oil carry out back and forth the one direction vacuum degassing between oil storage tank and transformer.The utility model overcome low, the ropy technical problem of existing regeneration efficiency in existing transformer insulation oil regeneration techniques, reduced because fault and the accident that the insulating oil quality problem occurs, and what make that transformer insulation oil can safety recycles.
