Abstract
The horizontal inner oil metal corrugated expansion oil conservator comprises an outer cover and a compensating body which is arranged in the outer cover and is composed of metal corrugated pipes, and is technically characterized in that: the inner cavity of the compensating body is communicated with the transformer oil tank through a supporting ring, and a supporting frame is arranged outside the compensating body and is arranged on the sliding guide rail. When the oil temperature of the transformer oil tank increases or decreases, the compensation body extends or retracts along the horizontal axis to drive the support frame to reciprocate on the sliding guide rail, so that the purpose of compensating the volume along with the change of the oil temperature of the transformer is achieved. Because the oil is filled in the metal corrugated pipe forming the compensation body, the support frame and the sliding guide rail are arranged outside the metal corrugated pipe and are not in the transformer oil, the transformer oil can not be polluted and the clamping stagnation phenomenon can not occur.
Description
Technical field:
The utility model relates to a kind of compensation arrangement with temperature of oil in transformer variation change volume, specifically a kind of horizontal interior oily metal bellow expansion oil storage tank.
Background technology;
Horizontal outer oily oil conservator is arranged on the market now, structurally it is that a metal bellows is contained in the metal housing of a sealing, one end communicates with atmosphere, the other end is shut, between wavy metal tube outside and metal housing, adorn transformer oil, and logical with the oil phase of transformer-cabinet, rely on the inflate compression bellows of oil in the oil tank of transformer and reach the purpose of volume compensation.Find that through operation in a few years there is following shortcoming in it: unstable in oil 1, because bellows is a flexible body, need directed pulley support guiding that sliding friction is arranged at the volley, therefore easily cause oil contaminated; 2, because bellows is a flexible body, very unstable, be easy to clamping stagnation at the volley, when external force acquired a certain degree, bellows overcame clamping stagnation, jerked, and easily caused the relay misoperation work, and then the serious accident that causes transformer to have a power failure; 3, this product is because about dual-seal, in case therefore bellows has leak source, snaps and will make in the oil leakage afferent echo line tube chamber, and having only the height of oil to surpass radius could overflow from the hole that connects atmosphere one end, and this moment, bellows was failure to actuate already; 4, because of the outer cover the inside action of bellows in sealing, the oil level misregister easily causes false oil level phenomenon.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of transformer oil and horizontal interior oily metal bellow expansion oil storage tank stable, that be convenient to maintain of can not polluting.
The purpose of this utility model is to realize like this, it comprises an outer cover and places the compensation body that is made of metal bellows in this outer cover, it is characterized in that: the compensation intracoelomic cavity is connected with oil tank of transformer by support ring, is provided with bracing frame in the outside of compensation body, and this bracing frame places on the rail plate.When the oily temperature of oil tank of transformer increased or descends, the compensation body drove bracing frame reciprocating motion on rail plate along horizontal axis elongation or withdrawal, reached with temperature of oil in transformer with this to change and the purpose of compensation volume.
The utility model is owing to be charge of oil in the metal bellows that constitutes the compensation body, and bracing frame and rail plate place outside the metal bellows, not in transformer oil, therefore pollutes transformer oil never, also catching phenomenon can not take place.Outer cover does not seal, and only plays a part dustproofly, rainproof, in case the phenomenon of snapping is arranged, then can find leak source immediately, is convenient to maintain.In addition, the oil level indication is directly perceived, accurate.
Below in conjunction with accompanying drawing the utility model is explained.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the B-B view among Fig. 1;
Fig. 3 is that K among Fig. 1 is to view;
Fig. 4 is the A-A view among Fig. 1.
Embodiment:
By accompanying drawing as can be known, the utility model mainly is made of outer cover 3, compensation body 4, bracing frame 8, guide rail 9, needle roller 13, support ring 2.Constitute rail plate by guide rail 9 and needle roller 13.The bracing frame 8 that is located at the compensation external body places (how much deciding according to the oil conservator size of this rail plate quantity on the rail plate, present embodiment provides three), compensation body 4 is made of metal bellows, its inner chamber is connected by support ring 2 and oil tank of transformer (do not draw among the figure, only provide the dish valve 11 that connects oil tank of transformer).After oil conservator and transformer install, dish valve 11 is opened.Because compensation body 4 inner chambers have been made evacuation processes before not installing, in be vacuum, transformer oil enters compensation body 4 through dish valve 11, open ball valve 7 then, behind the air-out, close ball valve 7, at this moment transformer forms closed state with compensation body 4, when the oil temperature is high,, drives bracing frame 8 and on rail plate, travel forward because the pressure effect forces compensation body 4 along the horizontal axis elongation; When oil temperature descends because vacuum action forces compensation body 4 closures, drive bracing frame 8 on rail plate toward swivel motion.Because compensation body 4 produces volume-variation, therefore make the oil in the transformation body keep rated operating pressure.Sequence number 1 is an indicating window among the figure, and sequence number 10 is a ring flange, and sequence number 12 is a footing.
