Abstract
The utility model relates to an oil purifying device for the oil inside the casing body in the process of transformer operation, which is connected with the transformer tank body into a communicated vessel via an oil outlet pipe flange (9) arranged on the shell (2) and an oil inlet pipe flange (10). The inner of the shell (2) is divided into two layers, namely, an upper and a lower by a clapboard (3); a filter element (4) is arranged on the upper layer and a drying agent is wrapped wherein; an oil pump (7) is arranged on the pipeline at the upper layer with which the oil inlet pipe (6) entering the lower layer of the shell (2) is communicated; the oil pump (7) is connected with an electromotor (8). The utility model can realize the function of forcing the oil to circulate for purification so as to quicken the circulation and purification of transformer oil in tank, completely purify the oil inside the case body and improve the security of operation of transformer.
Description
Technical field: the utility model relates to a kind of device that in the transformer running oil in the casing is purified, and belongs to the assembly of transformer.
Background technology: non-sealed transformer, in long-term running, can make airborne steam be brought into oil tank of transformer inside owing to fuel tank internal in the respiratory and outside air exchange, incorporate in the oil, the insulation property of transformer oil have been reduced, for eliminating the defective of bringing therefrom, the above transformer of regulation 3150kVA should be installed oil filter among the GB/T6451-1999.Transformer is installed in outside the fuel tank with oil filter and forms a container that is communicated with transformer-cabinet at present.Its structure is to load onto drier and adsorbent in the container that has oil inlet pipe and a flowline, and loads onto wire netting at oil inlet pipe and flowline, prevents that drier from being gone out by oil.Its operation principle is the temperature difference generation convection current by oil in the operating transformer-cabinet, the oil that makes casing enters oil filter from the oil inlet pipe of bottom, after impelling the drying and absorption that drives original oily rise process oil filter internal desiccant and adsorbent in the oil filter, flow back in the oil tank of transformer again from the flowline on top, form recurrent state, reach the purpose of clean oil with moisture content and impurity in dry and the absorption transformer oil.Its shortcoming is: 1. for the transformer of stable operation, the temperature difference of its top and bottom oil is little, so its inner convection current is very slow, and promptly purification speed is very slow.2. on the general transformer body oil filter only is installed, the interior a large amount of oil of transformer-cabinet can not be fully purified, be difficult to guarantee the long-term stability operation of transformer.
Summary of the invention: the purpose of this utility model is to provide a kind of transformer oil filter that can forced oil-circulation, accelerating the circularly purifying speed of transformer oil in the fuel tank, and the oil in the casing is fully purified, and improves the fail safe of transformer operation.
The utility model comprises a housing, housing is communicated with oil tank of transformer by the flowline flange on its top and the oil inlet pipe flange of bottom, form a linker, enclosure interior is divided into two-layer up and down by dividing plate, the filter core that the inside is enclosed with drier is placed on the upper strata, the oil inlet pipe of bottom passes dividing plate and inserts housing upper strata filter core, the motor that an oil pump is arranged and power is provided for oil pump on the in-line in housing lower floor through housing lower floor.
Description of drawings: Fig. 1 is a structural representation of the present utility model
Among the figure: 1-flowline 2-housing 3-dividing plate 4-filter core 5-drier 6-oil inlet pipe 7-oil pump 8-motor 9-flowline flange 10-oil inlet pipe flange 12-cover plate
Embodiment: further specify below in conjunction with accompanying drawing.Flowline flange 9 and oil inlet pipe flange 10 by oil filter housing 2 in the utility model are connected to the container that is communicated with oil tank of transformer.The cover plate 12 of housing 2 upper and lower end faces is convenient to change drier by bolted, and motor and oil pump are installed.Housing 2 inside are divided into two-layer up and down by dividing plate 3, there is filter core 4 on the upper strata, and drier 5 is wrapped in by filter core 4.Oil inlet pipe 1 enter after housing 2 lower floors with the connecting line of upper strata dividing plate 3 in oil pump 7 is arranged, oil pump 7 is connected with motor 8 again.When transformer moves, according to law of connected vessels, oil tank of transformer and oil filter housing 2 upper stratas all are full of oil, motor 8 drives oil pump 7 forces the oil in the casing to enter oil filter housing 2 upper stratas, flow back in the casing along flowline 1 by the oil that oozes out after drier 5 and filter core 4 processing, so circulation can be accelerated purification speed, and the oil of transformer-cabinet fully is purified.
Owing to adopt the oil pump forced oil-circulation, can make the whole intensive dryings of the interior oil of fuel tank filter to reach fully and purify, speed is fast, the efficient height.Also can carry out purified treatment to the oil in the transformer-cabinet at any time in addition according to actual conditions.
Claims (1)
1. the transformer oil filter of a forced oil-circulation, comprise a housing, housing is communicated with oil tank of transformer by the flowline flange on its top and the oil inlet pipe flange of bottom, form a linker, it is characterized in that: enclosure interior is divided into two-layer up and down by dividing plate, the filter core that the inside is enclosed with drier is placed on the upper strata, the oil inlet pipe of bottom is through housing lower floor, pass dividing plate and insert housing upper strata filter core, the motor that an oil pump is arranged and power is provided for oil pump on the in-line in housing lower floor.
