Abstract
The invention relates to a series type transformer oil fine filter which comprises a cylinder, a cover and a bottom plate, wherein an oil inlet pipe joint is arranged on one side of the cylinder and connected with an oil discharge port of an oil filter; an oil outlet pipe joint is arranged on the other side of the cylinder and connected with a transformer or oil tank; an oil inlet pipeline and an oil outlet pipeline are connected through a flange; coaxial 0.5mu m filter element and oil-through pipe are sequentially arranged from outside to inside in the cylinder; four universal wheels are arranged at the lower end of the bottom plate, can move flexibly and are connected with any oil filter. One level of 0.5mu m fine filter is added to the 3mu m filter at the oil discharge port of the oil filter, and the oil filtering efficiency of the transformer is greatly improved so that the hot oil circulation granularity of the 500kV transformer reaches the NAS3 level and the circulated hot oil of the 750kV transformer reaches NAS1 level.
Description
Technical field
The present invention relates to a kind of transformer oil filter, but especially a kind of tandem transformer oil fine filter.
Background technology
Transformer oil filter process and filtration of calor innatus oil circulation process use twin-stage high vacuum oil filter before injection transformer in the past; The index that Circulation and Hot Oil Spray finishes back Jie's damage, withstand voltage, little water, chromatogram can reach requirement, but the granularity index that 500kV level and above transformer require does not reach requirement.
Summary of the invention
To the problems referred to above, but the present invention proposes a kind of tandem fine filter, on the basis of twin-stage high vacuum oil filter oil drain out 3um filter, increased the one-level fine filter, improved the transformer oil filter efficiency greatly.
The present invention adopts following technical scheme: but a kind of tandem transformer oil fine filter; Comprise cylindrical shell, lid and bottom plate; A side is provided with inlet connector on cylindrical shell, is connected with the oil filter oil drain out, and opposite side is provided with flowline connection to subsea; Be connected with transformer or oil tank, in-line adopts flange to be connected with fuel-displaced pipeline.In cylindrical shell, be provided with coaxial filter core and pass through oil pipe, filter core with pass through oil pipe and be connected on the cylindrical shell through the ring flange of upper end and the ring flange of lower end.In cylindrical shell, respectively establish a back-up ring up and down, be close to the filter core inwall.In cylindrical shell, also be provided with sealing gasket and sealing ring.The filtering accuracy of said filter core is smaller or equal to 0.5um and greater than 3um.Transformer oil flows out from the oil filter oil drain out; The oil inlet pipe that connects through inlet connector enters into this fine filter; After the essence filtration through filter core; Get into and pass through oil pipe and flow into the flowline pipeline from the opening that passes through the oil pipe bottom, like this, the smart oil that filters of process just can flow directly into transformer or oil tank has suffered.The back-up ring that in cylindrical shell, is provided with plays fixation, is close to filter core, can prevent that filter core from moving.Filter core with pass through oil pipe and be connected on the cylindrical shell through ring flange, not only easy for installation, and be convenient for changing filter core.
Further, this fine filter flow and oil filter flow matches can guarantee that transformer oil flows into this fine filter reposefully from oil filter.
Further, cylindrical shell top is provided with Pressure gauge, and the bottom is provided with sample valve, the detection of can taking a sample at any time.
Further, be provided with four universal wheels, can move flexibly, be connected with any oil filter in the base plate lower end.
The invention has the beneficial effects as follows: on the basis of oil filter oil drain out 3um filter, increased the one-level fine filter; Improved the transformer oil filter efficiency greatly; Make 500kV transformer Circulation and Hot Oil Spray granularity reach NAS3 level level, reach NAS1 level level after the 750kV transformer Circulation and Hot Oil Spray.
Description of drawings
Fig. 1 is a partial sectional view of the present invention;
Among the figure: 1, lid, 2, sealing gasket, 3, sealing ring, 4, cylindrical shell, 5, pass through oil pipe; 6, filter core, 7, back-up ring, 8, inlet connector, 9, base plate; 10, universal wheel, 11, Pressure gauge, 12, flowline connection to subsea, 13, ring flange; 14, ring flange, 15, sample valve, 16, ring flange, 17, ring flange.
Embodiment
As shown in the figure; But a kind of tandem transformer oil fine filter comprises cylindrical shell 4, lid 1 and base plate 9, and a side is provided with inlet connector 8 on cylindrical shell 4; Be connected with the oil filter oil drain out; Opposite side is provided with flowline connection to subsea 12, is connected with transformer or oil tank, and in-line adopts flange to be connected with fuel-displaced pipeline.In cylindrical shell 4, be provided with coaxial filter core 6 and pass through oil pipe 5, filter core 6 with pass through oil pipe 5 and be connected on the cylindrical shell 4 through the ring flange of upper end and the ring flange of lower end.In cylindrical shell 4, respectively establish a back-up ring 7 up and down, be close to, can prevent that filter core from moving with filter core.In cylindrical shell 4, also be provided with sealing gasket 2 and sealing ring 3.The filtering accuracy of filter core is 0.5um.Transformer oil flows out from the oil filter oil drain out, because this fine filter flow and oil filter flow matches, so transformer oil can flow into this fine filter from oil filter reposefully.The oil inlet pipe that connects through inlet connector 8 enters into this fine filter; After the essence filtration through 0.5um filter core 6; Get into and pass through oil pipe 5 and flow into flowline through flowline connection to subsea 12 connections from the opening that passes through oil pipe 5 bottoms; Like this, the oil that filters through essence just can flow directly into transformer or oil tank has suffered.
The cylindrical shell bottom is provided with sample valve 15, and if the detection Quality of Transformer Oil of can taking a sample at any time qualified, continue to be filtered, if transformer oil is off quality, can stop to carry transformer oil to be filtered to this fine filter, seeks reason, in time renew cartridge more.
Be provided with four universal wheels 10 in base plate 9 lower ends, can move flexibly, be connected with any oil filter.
