Abstract
The utility model discloses an external transformer oil filtering device which comprises a transformer and further comprises an oil pump, a filtering box and a sealed fan. A threaded hollow upper leading-out pipe is arranged at the upper end of the transformer, a threaded hollow lower leading-out pipe is arranged at the lower end of the transformer, valves are arranged on pipelines between the transformer, the oil pump and the filtering box, the filtering box is connected to the oil pump, the oil pump, the sealed fan and an electric motor are sequentially connected, and the electric motor is connected with a time relay. The external transformer oil filtering device has the advantages that a circulating beginning point is arranged at the bottom of the transformer to reinforce brushing of circulating oil to the bottom and fully filter out sedimentation metal at the bottom; by means of control of the time relay, external oil circulation can be established according to setting time to achieve the purposes of automatically filtering transformer oil and keeping the oil quality; the sealed fan effectively prevents the oil leakage phenomenon of an oil pump; the external transformer oil filtering device is more practical.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of external transformer oil filtering device.
Background technology
Transformer oil is as transformer insulated and cooling medium, and the quality of its quality is directly connected to the safe and stable operation of transformer.But the transformer oil moving all contains a certain amount of metal ingredient to some extent, its source mainly contains three aspects: the one, and transformer oil is brought in its production process; The 2nd, in transformer Installation and Debugging process, bring into; The 3rd, in transformer running, produce gradually.Therefore after transformer long-time running, the metal micro particles in radiator is circulated and is entered transformer body by oil, makes transformer oil in transformer by metallic particles severe contamination, thereby causes oily insulation property variation, uses and has brought potential safety hazard to the later stage.The processing of the transformer oil to metal severe contamination, the simplest method is exactly renew oil more, but more renew oil cost is too high; Another kind of is exactly to the transformer oil processing of regenerating, but its complicated operation, and cost price is also very large.
Utility model content
For the weak point in addressing the above problem, the utility model provides a kind of external transformer oil filtering device.
For solving above technical problem, the technical solution adopted in the utility model is: a kind of external transformer oil filtering device, comprise transformer, and it also comprises oil pump, filter cartridge, seal fan; The upper end of transformer is provided with extraction tube on thread hollow, lower end is provided with extraction tube under thread hollow;
On pipeline between transformer and oil pump, filter cartridge, be respectively provided with a valve; Described filter cartridge is connected on oil pump;
Oil pump, seal fan, motor three successively order are connected;
Motor is connected with the time relay.
On thread hollow, extraction tube is all connected with external pipeline with extraction tube under thread hollow and seals with seal washer.
Seal fan is connected with the driving shaft outlet of oil pump by a hollow cylinder outer cover.
The oil pump end of hollow cylinder outer cover has multiple exhaust holes.
The beneficial effects of the utility model are: 1, loop start is based upon the bottom of transformer, can strengthen recycle oil to the washing away of bottom, and the precipitation metal of bottom is filtered fully.2, the filter core of design is dismountable, can regularly change filter core, and can adopt the filter core of different qualities to carry out a certain index to transformer oil to clear up targetedly.3, adopt time relay control, set up external oil circulation by setup times, reach automatically transformer oil is filtered, keep oily object.(4) adopt seal fan, effectively prevented issuing licence of operation of oil pump oil leakage phenomenon; More convenient and practical.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1, transformer; 2, oil pump; 3, filter cartridge; 4, seal fan; 5, motor; 6, valve; 7, exhaust hole 8, the time relay; 9, extraction tube on thread hollow; 10, extraction tube under thread hollow.
Embodiment
As shown in Figure 1, the utility model comprises on transformer 1, oil pump 2, filter cartridge 3, seal fan 4, motor 5, valve 6, exhaust hole 7, the time relay 8, thread hollow extraction tube 10 under extraction tube 9 and thread hollow.
The upper end of transformer is provided with extraction tube 9, lower end on thread hollow and is provided with extraction tube 10 under thread hollow.On thread hollow, extraction tube 9 is all connected with external pipeline with extraction tube under thread hollow 10 and seals with seal washer.On pipeline between transformer 1 and oil pump 2, filter cartridge 3, be respectively provided with a valve 6.Filter cartridge 3 is connected on oil pump 2.Oil pump 2, seal fan 4, motor 5 threes successively order are connected.Motor 5 is connected with the time relay 8.
Under thread hollow, the removing that the pollution foreign material that can conveniently be deposited on transformer 1 bottom are set of extraction tube 10, reaches better filter effect.
When connection, the gland seal system of oil pump adopts leakoff-type shaft seal, and concrete condition is seen the pressure size of on-the-spot oil circulation and determined.Reach inactive state oil-proof.
Seal fan 4 is connected with the driving shaft outlet of oil pump 2 by a hollow cylinder outer cover, has multiple exhaust holes 7 at oil pump 2 ends of hollow cylinder outer cover, and guarantee can provide suitable pressure condition, can prevent again air intrusion transformer 1.
The pressure head of seal fan is also set according to the pressure drop of maximum oil pressure and leakoff-type shaft seal.When connection, operating personnel can, according to on-the-spot concrete condition, select to arrange the fixed position of each device, and length of pipe is determined according to scene.The time relay 8 of configuration, can carry out the setting of time.
Above-mentioned execution mode is not to restriction of the present utility model; the utility model also not instrument be limited to above-mentioned for example; variation, remodeling, interpolation or replacement that those skilled in the art make within the scope of the technical solution of the utility model, also all belong to protection range of the present utility model.
