Abstract
The utility model relates to a compensation arrangement that the volume changes along with the change of transformer oil temperature, specifically speaking is a metal corrugated expansion oil storage cabinet, personally experience sth. Part of the body and set up in the internal a plurality of corrugated metal inflation body of this cabinet including the cabinet, cabinet each internal corrugated metal inflation body is independent seal, every the top of the corrugated metal inflation body do not is equipped with valve A, lower part and is equipped with valve B, every respectively the valve A on corrugated metal inflation body upper portion is linked together with the cabinet is external through exhaust pipe respectively, every the valve B of corrugated metal inflation body lower part is linked together with transformer tank through defeated oil pipe way respectively. The utility model discloses an upper portion and lower part that cabinet each internal corrugated metal inflation was personally experienced sth. Part of the body have set up the valve respectively, constitute seal structure independent separately. In case one of them corrugated metal inflation body breaks down, valve about can closing, with the disconnection of whole oil piping system, the system still can move temporarily, has reduced loss of outage, more square easy access simultaneously.
Description
Technical field
The utility model relates to the compensation arrangement that volume changes with temperature of oil in transformer change, specifically a kind of metal bellow expansion oil storage tank.
Background technology
At present, the metal bellow oil conservator used in electric power system, primarily of an outer cover be placed in one or more wavy metal expanding core body in this outer cover and form in structure.By the gas exhaust piping on top and the mutual UNICOM of pipeline road of bottom between multiple wavy metal expanding core body, form a compensating body.The inner charge of oil of compensating body, outside communicates with air; Problems existing is: once wherein a wavy metal expanding core body breaks down, and just must have a power failure process immediately, because each wavy metal expanding core body does not install independently valve, can not disconnect with system.Therefore, the insulating oil of whole compensating body inside all must be bled off when overhauling this core body, both waste manpower and materials, and too increased Maintenance and Repair cost simultaneously.
Utility model content
In view of the weak point that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of metal bellow expansion oil storage tank.Be provided with multiple ripple expander in the cabinet of this metal bellow expansion oil storage tank, each ripple expander have independently hermetically-sealed construction, can be interconnected again.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises cabinet and is arranged at the multiple wavy metal expanders in this cabinet, each wavy metal expander in described cabinet is independently seal, the top of each described wavy metal expander is respectively equipped with valve A, bottom is respectively equipped with valve B, the valve A on each described wavy metal expander top is connected with outside cabinet respectively by gas exhaust piping, and the valve B of each described wavy metal expander bottom is connected with oil tank of transformer respectively by pipeline road.
Wherein: after the gas exhaust piping that each described wavy metal expander upper valve A connects converges, be connected with outside described cabinet, after the pipeline road that each described wavy metal expander bottom valve B (5) connects converges, be connected with described oil tank of transformer; Be interconnected by gas exhaust piping or pipeline road between each described wavy metal expander; Described valve A and valve B is butterfly valve, ball valve or vacuum valve.
Advantage of the present utility model and good effect are:
The upper and lower of each wavy metal expander in cabinet of the present utility model is provided with valve respectively, forms separately independently hermetically-sealed construction.Once one of them wavy metal expander breaks down, can close lower valve, disconnect with whole oil piping system, system still can be run temporarily, reduces loss of outage, is more convenient for maintenance simultaneously.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model;
Wherein: 1 is cabinet, 2 is wavy metal expander, and 3 is gas exhaust piping, and 4 is valve A, and 5 is valve B, and 6 is pipeline road.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises cabinet 1 and is placed in the multiple wavy metal expanders 2 in this cabinet 1, each wavy metal expander 2 in cabinet 1 is independently seal, the top of each wavy metal expander 2 is respectively equipped with valve A4, bottom is respectively equipped with valve B5, the valve A4 on each wavy metal expander 2 top is connected to gas exhaust piping 3, and the valve B5 of bottom is connected to pipeline road 6; After the gas exhaust piping 3 that each wavy metal expander 2 upper valve A4 connects converges, be connected with outside cabinet 1, after the pipeline road 6 that each wavy metal expander 2 bottom valve B5 connects converges, be connected with oil tank of transformer.When valve A4 and valve B5 opens, the gas exhaust piping 3 of wavy metal expanding core body 2 by top and pipeline road 6 UNICOM mutually of bottom, form an overall ripple expansion compensation body, the inner chamber of this compensating body is all full of iknsulating liquid, is inner oil type structure, the pipeline road 6 of bottom is communicated with oil tank of transformer, defines hermetic oil piping system.
Valve A4 of the present utility model and valve B5 can be butterfly valve, ball valve or vacuum valve.
Operation principle of the present utility model is:
During operation, when transformer oil temperature raise or reduce time, each wavy metal expander 2 along axis oriented normal direction synchronous or expansion, the change of compensator transformer oil volume.Wavy metal expander 2 once one of them breaks down, and the valve B5 of the valve A4 on out of order wavy metal expander 2 top and bottom can be closed, disconnect with whole oil piping system, influential system does not run temporarily.Can recover and system communication after the maintenance of this wavy metal expander 2, maintenance is convenient, cost saving, ensures system safety operation.
