The pointer-type oil level indicator has the advantages that the oil level indicator radically solves the problem in sealing oil in the oil level indicator and an oil conservator of a transformer, thereby isolating the transformer oil from the solar irradiation and accurately indicating the oil level; and the oil level indicator can prevent aging of the oil material due to irradiation and has the advantages of simple structure, economic and practical use, high reliability, convenient maintenance, etc.
Description
Technical field
The utility model relates to the oil level display device, especially a kind of pointer type fuel level indicator.
Background technology
The transformer oil conservater will play the indication oil level, carry out the effect that oil degradation was breathed and prevented to oil under the product normal operation, can it is directly connected to transformer safely, stablely reach long-time running.
In existing middle low capacity, open type oil immersed power transformer structural design, the oil level indicator of institute's adapted oil conservater adopts plane oil meter or glass tubular type oil meter usually.In adopting plane oil meter structure indication oil conservater during oil level, because the normal oil colours of transformer is yellowish Transparent color, and aberration is less between the oil meter base plate, the rolling inspection personnel are difficult for from observing the transformer oil level at a distance, and transformer oil directly is subjected to can quickening oil deterioration after the effect of solar irradiation, and the insulating capacity of oil product is descended, and dielectric loss raises, to the corrosion of metal parts product, influence the heat radiation of heat generating components.When adopting glass tubular type oil meter, though red ball float is housed in the glass tube, the oil level indication is eye-catching, is convenient to the operation maintenance personnel and observes oil level, and is same because transformer oil is subjected to the effect of solar irradiation, easily makes oil colours deepen aging, quality badness.Simultaneously because glass tube and red ball float are very easily damaged, to having relatively high expectations of installation and transportation aspect.
Since in transformer plane oil meter and the glass tubular type oil meter oily all with oil conservater UNICOM, the ageing oil in the oil meter is easily sneaked in the oil conservater, even enters in the transformer body fuel tank, makes product electrical insulation properties deterioration.Transformer oil starvation and oil degradation all directly have influence on the safe operation of transformer.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the sealing problem between oil level indicator housing and ball float fork, the utility model provides a kind of non-contacting magnetically-actuated mode, and the oil level indicator pointer is rotated, and points out the variation of oil level.Oil level indicator pointer and panel can be sealed in the housing of an oil resistant like this, thereby the oil in complete and the transformer oil conservater is isolated, and pointer indicates the oil level at ball float place to change by magnetically-actuated in the oil level indicator.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of pointer type fuel level indicator, it comprises: housing, pointer, be installed on sleeve pipe on the housing, be installed on needle pivot and transmission shaft in the described sleeve pipe, described needle pivot and described transmission shaft link by magnetic coupling, vertically connect fly rod at described transmission axle head, one end of described fly rod is connected with ball float, described sleeve pipe is the blind hole structure, described sleeve pipe two ends are coated with needle pivot and transmission shaft respectively, two extreme position that described transmission shaft rotates, be provided with limited block on the described sleeve pipe, on the transmission shaft of the relevant position of described limited block, limit shaft is installed, the link place of described transmission shaft and described fly rod, on transmission shaft, offer the mounting hole that adapts with the fly rod external diameter, described fly rod one end stretches into described mounting hole and is connected with described transmission shaft by fastening bolt, add fulcrum between described sleeve pipe and the described transmission shaft, described fulcrum is fixedlyed connected with described sleeve pipe, described fulcrum is to be connected by bolt with described sleeve pipe, described pointer external coating reflectorized material, index dial also is installed in the housing that is coated with described needle pivot side, scribbles reflectorized material on the index dial surface.
The beneficial effects of the utility model are, fundamentally solved the sealing problem of the oil in oil level indicator and the transformer oil conservater, transformer oil and solar irradiation are isolated, can correctly point out simultaneously the oil level height again, the oil plant of avoiding causing because of illumination wears out, and simple in structure, economical and practical, the reliability height is convenient to safeguard etc.

Embodiment
As shown in Figure 1, a kind of oil level indicator comprises: housing 1, pointer 3, end at housing 1 is coated with sleeve pipe 5, needle pivot 7 and transmission shaft 9 are threaded onto the both sides of sleeve pipe 5 respectively, and sleeve pipe 5 is the blind hole structure, and needle pivot 7 is connected by magnetic coupling 11 with transmission shaft 9, magnetic coupling 11 is made up of two radial magnet, lays respectively at the both sides of sleeve pipe 5.In by the housing 1 that needle pivot 7 one sides are housed, housing 1 bottom is equipped with pointer scale dish 13, in addition, be coated with radial magnet, pointer 3 on the needle pivot 7 successively, and radial magnet, pointer 3 are fixedlyed connected with needle pivot 7, and clear glass 15 is installed on housing 1 then, and with trim ring 17 cappings.Because pointer 3 has reflectorized material with the external coating of pointer scale dish 13, so, even, also can come into plain view in night observation oil level situation.
In the sleeve pipe 5 that is coated with transmission shaft 9, radial magnet, fulcrum 18, limit shaft 19 and fly rod 21 are installed on transmission shaft 9 successively, radial magnet is fixedlyed connected with transmission shaft 9, and fulcrum 18 is fixedlyed connected with sleeve pipe 5, and with bolt 23 that fulcrum 18 is fixing with sleeve pipe 5, thus transmission shaft 9 is played the perpendicular positioning effect.Two extreme position in that transmission shaft 9 rotates are provided with limited block 25 on the sleeve pipe 5, on the transmission shaft 9 of the relevant position of limited block 25 limit shaft 19 is installed, and are used to control the maximum and the minimum angles of transmission shaft 9 rotations.The link place of transmission shaft 9 and fly rod 21, on transmission shaft 9, offer the mounting hole 27 that adapts with fly rod 21 external diameters, fly rod 21 1 ends stretch into mounting hole 27 and are connected with described transmission shaft 9 by fastening bolt 29, screw tight and fixing fly rod 21 length with nut 31, fly rod 21 length change with transformer oil conservater diameter, regulate by fastening bolt 29.At last, ball float 33 is installed on the fly rod 21.
As Fig. 2 and Fig. 3, pointer type fuel level indicator is installed on the oil conservater, for preventing to leak, so increased seal 35 at the installed surface of oil level indicator and oil conservater.When transformer moves, variation along with environment temperature and load, temperature of oil in transformer will change, the transformer pasta changes because of the contraction of oil, the variation of expanding, ball float 33 moves along with the lifting of pasta, this moment, the ball float 33 of corresponding oil level indicator drove fly rod 21 deflections, fly rod 21 sends deflection force to transmission shaft 9, radial magnet on the transmission shaft 9 is rotation thereupon also, according to magnetic induction principle, the radial magnet that is connected with needle pivot 7 is rotation and then, and then needle pivot 7 drive pointers 3 are inclined to one side, and the indication oil level changes.
