Technical field
The utility model relates to a kind of power transformer and uses oil conservator, particularly a kind of bellow oil conservator with oil-level way of output.
Background technology
The employed novel corrugated oil conservator of power transformer is widely used with long service life, characteristics such as non-maintaining.Oil level shows and supervisory control system has become one of requisite annex of oil conservator.It is inner and use electronic component that existing oil level supervisory control system is installed on oil conservator, though the life-span of electronic component can reach tens thousand of hours, compares with the useful life of bellow oil conservator and be nowhere near.Change or safeguard being installed in the inner electronic component of oil conservator, often will open oil conservator, even need transformer to have a power failure, thereby give and use and management makes troubles.
Traditional pointer type fuel level indicator has oil level and observes characteristics such as clear, that replacing is convenient, transmits oil level information but traditional pointer type fuel level indicator is the ball float drive power transmission shaft that is placed in the oil conservator, and this structure is not suitable for hermetic corrugated oil conservator.Though have the bellow oil conservator of minority that the magnetic-type oil level indicator has been installed at present, to be the oil level collection terminal be connected with ripple near the oil conservator end plate its connected mode (i.e. stretching, extension through ripple change gather oil level information).Because in the oil conservator running, all the ripple stretching, extension is not uniformly, so this kind magnetic-type oil level indicator transmission oil level information error is very big, false oil level often occurs.And, therefore must open oil conservator and change user's troublesome maintenance owing to comprise that whole devices of electronic component are installed in oil conservator inside.
China's electrical network is to digitlization, intelligent development at present, and following power grid construction must be also with new technology innovation is constantly arranged.If because of the electric network information transformation will not changed to the bellow oil conservator in useful life; Certainly will cause the too much wasting of resources; This just needs the oil level display monitoring device of oil conservator to possess the function of upgrading, upgrading at net, satisfies the intelligent needs of building of electrical network.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of oil-level measurement intelligent bellow oil conservator accurate, easy to maintenance.
The utility model is realized through following technical proposals: intelligent bellow oil conservator; Comprise the bellow oil conservator body; In the oil conservator body, be provided with the oil level transmission device; The oil level transmission device is fixed in the stainless steel coiling of also passing through self on the oil conservator front end housing and is connected with the oil conservator movable end, transmits oil level information through moving horizontally of oil conservator movable end; Said oil level transmission device output is provided with the magnetic drives piece, outside the oil conservator body, is provided with the oil level display unit, and its receiving terminal is provided with the magnetic drives piece, and oil level transmission device and oil level display unit are through the magnetic force couple transmission oil level information of magnetic drives piece.
Described oil level transmission structures: decelerator, torsion box and bracing frame are installed on fixed mount; Steering module is installed on the bracing frame, and the stainless steel coiling is wrapped on the wire spool that has the track that winds the line through steering module, and its end is connected with the oil conservator movable end; Wire spool is fixed on the reducer input shaft; And drive reducer input shaft and rotate synchronously, reducer output shaft has gap, is used to clamp the inner of scroll spring; The outer end of scroll spring is by the locking of torsion box, and the reducer output shaft end is installed the magnetic drives piece.
The beneficial effect of the utility model: the utility model adopts said structure, and the displacement of movable end can embody real oil level, therefore can transmit oil level information accurately through moving horizontally of oil conservator movable end; The oil level transmission device can change the radially rotation that converts the magnetic force coupling block into the straight line of oil conservator movable end, has therefore simplified the structure of oil level indicator greatly.
Owing to adopt magnetic-coupled transfer mode to realize that oil level display unit and oil conservator inside isolate fully, therefore can under the oil conservator running status, at any time oil level indicator be changed and safeguard; When reinstalling oil level indicator, oil level indicator can also demonstrate oil level information accurately through the searching oil level of magnetic coupled system intelligence.
Can also in oil level indicator, increase and report to the police and the analog signal output function according to different needs, realize digitlization, Intellectualized monitoring.

Embodiment
The structure chart of the utility model is as shown in Figure 1.It is mainly by shell body 1, corrugated expansion joint 2, and oil conservator front end housing 8, oil conservator movable end 11, oil level transmission device 7 and oil level display unit 4 are formed.Corrugated expansion joint 2 is loaded on shell body inside; The connector 10 that shell body 1 has exhaust outlet 3, pouring orifice 9 and connects oil tank of transformer.Oil conservator front end housing 8 has the pneumostome 6 that communicates with ambient atmosphere.
Oil level transmission device 7 is installed on oil conservator front end housing 8 places, and is connected with oil conservator movable end 11 through self stainless steel coiling, and oil level display unit 4 is installed in the oil conservator outside, and by oil conservator seal plate 5 with isolating inside and outside the oil conservator.
Oil level transmission device 7 structures are as shown in Figure 2: wire spool 12 is fixed on the reducer input shaft 13 and drives reducer input shaft 13 and rotates synchronously.Reducer output shaft 17 has the inner that gap is used to clamp scroll spring 16, and the outer end of scroll spring 16 is by 15 lockings of torsion box.The reducer output shaft 17 terminal magnetic drives pieces 18 of installing.Decelerator 14, torsion box 15, bracing frame 20 are fixing by fixed mount 19 respectively.Bracing frame 20 is equipped with steering module 21, and stainless steel coiling 22 is wrapped on the wire spool 12 that has the track that winds the line through steering module 21, and its end is connected with oil conservator movable end 11.This device provides tensile force by oil conservator movable end 11, by scroll spring 16 convergent force is provided, and stainless steel coiling 22 is in tension all the time.
