Abstract
A vertical type inner oil conservator for a transformer comprises a tank body and a corrugated expansion box arranged in the tank body, wherein an upper cover plate moving up and down along the inner wall of the tank body is arranged at the top end of the corrugated expansion box; an exhaust opening and a collector box are arranged on the upper cover plate; and an oil inlet communicated with the corrugated expansion box is formed on the lower cover plate of the corrugated expansion box. The utility model adopts the technical points that the exhaust pipe of the collector box adopts a high pressure resistant DN 20 corrugated pipe connected with an exhaust valve extending out the bottom of the tank body; a collection room is arranged at the oil inlet of the corrugated expansion box; and the collection room is equipped with a waste discharging plug. The high pressure resistant exhaust pipe can not be damaged easily while moving inside the corrugated expansion box, and can reduce oil storage level; and the collection is arranged at the oil inlet, so that precipitates and sewage can be discharged periodically. The utility model has the advantages of purifying the oil quality of the transformer, and prolonging the service life of the oil and the corrugated expander of the transformer.
Description
Technical field:
The utility model relates to a kind of safety guard that is used for power transformer, and a kind of specifically transformer is with oily oil conservator in vertical.
Background technology:
To be that 200520092154.4 " multifunction storage Oil Tank " rubber of once existing at existing capsule-type, diaphragm type, wavy metal formula, conservator or oil conservator is easily aging, fragile can produce the transformer oil quality deterioration to the patent No., easily long-pending dunghill in the original inner oil type of seepage oil, the metal bellow type oil conservator, damage the ripple expansion character, influence its problem such as safe operation in useful life and done further improvement, better solved the defective that prior art exists to a certain extent.But also have the operation process complexity, the gas exhaust piping range ability is too high, and is fragile.Because of all dead sealings of weldering of metal bellow type oil conservator, and oil-out has only one, dunghill after several years in the metal bellow type oil conservator will more amass the more, each ripple unit is flexible inconsistent, then will influence the normal reciprocating motion of ripple, make the Buchholz relay would trip, serious damage ripple is difficult to guarantee the safe operation of metal corrugated pipe oil tank in useful life.
Summary of the invention:
The purpose of this utility model provides a kind ofly has the transformer that purifies transformer oil function, prolong transformer oil and bellow expander useful life with vertical interior oily oil conservator.
The purpose of this utility model is to realize like this, it comprises cabinet and places the interior ripple expansion box of this cabinet, the top of this ripple expansion box is provided with the upper cover plate that moves up and down along the cabinet inwall, upper cover plate is provided with exhaust outlet and collector box, be provided with the oil-in that is communicated with the ripple expansion box on the lower cover of ripple expansion box, it is characterized in that: vent valve outer at the bottom of the blast pipe in the collector box adopts high pressure resistant DN20 bellows and stretches out the cabinet cabinet links to each other; Oil-in place at the ripple expansion box is provided with collecting sewage room, and this collecting sewage room is provided with puts dirty plug.
It is not fragile to the utility model has the advantages that high pressure resistant blast pipe moves in the ripple expansion box, and can reduce the height of oil storage; The place is provided with collecting sewage room at oil-in, the precipitation dunghill regularly can be discharged.Make it to purify transformer oil, prolong transformer oil and bellow expander useful life.
Below in conjunction with accompanying drawing the utility model is done with explanation.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the upward view of Fig. 1.
Embodiment:
By accompanying drawing as can be known, the utility model comprises by cabinet lid 14, cabinet 1,9 oil conservators that constitute and being arranged in this oil conservator at the bottom of the cabinet by upper cover plate 3, lower cover 4, the ripple expansion box that bellow expander 2 constitutes, be provided with upper cover plate 3 on ripple expansion box top, move up and down along cabinet 1 inwall by the pulley 13 that is provided with on the upper cover plate 3, upper cover plate 3 is provided with exhaust outlet and collector box 5, be provided with the oil-in 11 that is communicated with the ripple expansion box on the lower cover 4 of ripple expansion box, vent valve 8 outer at the bottom of the blast pipe in the collector box 5 adopts high pressure resistant DN20 bellows 6 and stretches out the cabinet cabinet links to each other; Oil-in place at the ripple expansion box is provided with collecting sewage room 12, and this collecting sewage room is provided with puts dirty plug 10.To precipitate dunghill and regularly discharge by putting dirty plug 10.Sequence number 7 is the connection in series-parallel pipeline road among the figure.
Temperature changes in transformer, and temperature raises, and the insulating oil volume is big, and oil is through oil-in 11 in the oil tank of transformer, and the transformer insulation oil that enters in the ripple expansion box constantly increases, and upper cover plate 3 is risen gradually.Oil volume reduces when the temperature in the transformer reduces, and upper cover plate 3 descends, can be flexible up and down with the oil volume freedom, and adapt to oil volume and change, guarantee transformer oil and air insulated, basic protection oil prolongs the service life of transformer oil, reaches non-maintaining.
