The utility model relates to transformer oil vacuum filtering system.It comprises oil tank of transformer (1), it is characterized in that: it also includes coarse filter (2), heater (3), vacuum chamber (4), fine filter (6), purpose ceramic-film filter (7) and vacuum suction pipeline (8); Described oil tank of transformer (1) is communicated with described fine filter (6) with described coarse filter (2), described heater (3), described vacuum chamber (4) successively and forms a closed circuit; Described fine filter (6) also described purpose ceramic-film filter (7) is communicated with, and described purpose ceramic-film filter (7) is also communicated with described oil tank of transformer (1); Described vacuum chamber (4) is also communicated with described vacuum suction pipeline (8).After adopting this transformer oil vacuum filtering system process, the oil quality of gained is high, and it has processing time short, the advantage such as working strength is low.
Description
Technical field
The utility model relates to electric power electric oil-filled equipment house transformer oil filtration technology, particularly relates to transformer oil vacuum filtering system.
Background technology
The transformer oil that electric power electric oil-filled equipment is used, because of constantly in oxidation electric discharge, spark and use under the environment such as high temperature, easily cause oil product aging and then produce a large amount of greasy filth and other contamination precipitations.These impurity are dissolved in oil in a large number can have a strong impact on oil quality, therefore needs to cross pointedly to filter.At present, in conventional application, the filter process of transformer oil, mainly adopts bipolar vacuum oil-filter repeatedly repeatedly to filter, carries out dewatering and removing impurity, although it can reach part improve oil product cleannes grade, but such filter type is time-consuming longer, have impact on efficiency, simultaneously because its filter core is limited in one's ability, to impurity treatment DeGrain, not easily up to standard, thus truly can not handle well cuts well, solve the oily requirement of high accuracy; Even if it can reach oil purification requirement when filtering, but also need not stop the long period of circulating.Such as, cleannes are the transformer oil of the untreated impurity of NAS9 level by employing conventional bipolar vacuum oil-filter, and after filtering 4 times, its cleannes are NAS7 level, and after filtering 12 times, its cleannes just can reach NAS5 level.In addition, existing bipolar vacuum oil-filter be through filter core add high accuracy step by step and realize filter, because the material that its high-precision filter element is used is stationery filter core, with not cleaning after mistake, thus its consumables cost is too high, causes unnecessary waste.
Utility model content
The purpose of this utility model is to provide transformer oil vacuum filtering system, and after adopting this transformer oil vacuum filtering system process, the oil quality of gained is high, and it has processing time short, the advantage such as working strength is low.
The purpose of this utility model is achieved in that
Transformer oil vacuum filtering system, it comprises oil tank of transformer, it is characterized in that: it also includes coarse filter, heater, vacuum chamber, fine filter, purpose ceramic-film filter, vacuum suction pipeline, lobe pump and vavuum pump; Described oil tank of transformer is communicated with described coarse filter, described heater, described vacuum chamber and described fine filter successively and forms a closed circuit; Described fine filter is also communicated with described purpose ceramic-film filter, and described purpose ceramic-film filter is also communicated with described oil tank of transformer; Described vacuum chamber is also communicated with described vacuum suction pipeline; Described vacuum suction pipeline is communicated with described vavuum pump with described lobe pump successively.
As further optimizing, above-mentioned transformer oil vacuum filtering system, also includes oil outlet pump; After above-mentioned vacuum chamber is communicated with described oil outlet pump, then be communicated with above-mentioned fine filter.
The utility model has following beneficial effect:
It is high that this transformer oil vacuum filtering system has filter capacity oil quality that is strong, that process rear gained, the features such as the processing time is short, and working strength is low, and consumables cost is low, ceramic membrane is capable of washing.This system takes off micro-water, removing impurities matter function significantly strengthens, and only needs disposable process just can realize the up to standard oil processing of cleannes up to NAS5 level.
Accompanying drawing explanation
Fig. 1 is the structural representation of transformer oil vacuum filtering system described in the utility model embodiment 1.
Detailed description of the invention
Be below the utility model preferred embodiment, be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Figure 1: transformer oil vacuum filtering system, it comprises oil tank of transformer 1, coarse filter 2, heater 3, vacuum chamber 4, oil outlet pump 5, fine filter 6, purpose ceramic-film filter 7, vacuum suction pipeline 8, lobe pump 9 and vavuum pump 10; Its oil tank of transformer 1 forms a closed circuit by pipeline connection with coarse filter 2, heater 3, vacuum chamber 4, oil outlet pump 5, fine filter 6 successively; Its fine filter 6 is also communicated with purpose ceramic-film filter 7, and this purpose ceramic-film filter 7 is also communicated with oil tank of transformer 1; Wherein, vacuum chamber 4 is also communicated with vacuum suction pipeline 8, and this vacuum suction pipeline 8 is also communicated with vavuum pump 10 with lobe pump 9 successively.
By the transformer oil vacuum filtering system of gained in the present embodiment 1, when being in the filter process of the transformer oil of the untreated impurity of NAS9 level for cleannes, oil product to be joined coarse filter 2 through oil circuit pipeline from oil tank of transformer 1 and tentatively filters, successively again through vacuum chamber 4 after heater via 3 heats, oil outlet pump 5, fine filter 6 and oil tank of transformer 1 circulate to remove micro-water, and the impurity that coarse filtration is large, treat that transformer oil oil temperature reaches 50 DEG C, when moisture content reaches requirement standard, close the circulation filtering pipeline between fine filter 6 and oil tank of transformer 1, and open purpose ceramic-film filter 7 simultaneously, to filter out the fine impurity in oil, work for the treatment of shutdown system is completed after qualified.Can be obtained by oil sample analysis of experimental data in whole processing procedure, this transformer oil vacuum filtering system is adopted only to filter 1 time, the up to standard oil of cleannes up to NAS5 level can be obtained, after its process, gained oil quality is high, and this processing procedure has time short, the advantage such as working strength is low, consumables cost is low, ceramic membrane is capable of washing.
