Description
Technical field
The utility model relates to a kind of tranformer protection equipment, particularly a kind of transformer body protective device.
Background technology
Power transformer is one of most important equipment in power plant and transformer station, wherein the most frequently used is oil-immersed type transformer, transformer oil is one of material forming transformer main insulation, with regard to insulation, special in extra-high-voltage large-capacity transf, the height of its gas content of oil has considerable influence to transformer insulated, this forms bubble because gas may gather together in equipment, particularly suddenly decline when temperature and pressure and the bubble that formed, be gathered in insulating paper layer or time surperficial and easily produce partial discharge.When the flow velocity that power transformer interior fault makes fuel tank flow to conservator increases, Buchholz relay action: when power transformer interior fault makes tank pressure increase, the earth pressure release actuating of relay; For forced oil-circulation air-cooled transformer, when cooling system decompression, oil temperature sharply raises, and makes overtemperature tripping relay and the air-cooled disappearance actuating of relay.Above protection relay action tripping operation, and send corresponding signal.Light Buchholz relay action is caused: when oil temperature being raised when transformer overload, the too high actuating of relay of temperature: when transformer cooling system power supply disappears, the air-cooled disappearance actuating of relay when minor failure occurs in power transformer inside or oil level declines; The action of above protection relay is in signal.The problem of transformer leakage of oil is easily there is in the transformer course of work; do not exit in time after inside transformer repairing; air accumulation is in Buchholz relay; oil level indicator vacation instruction; the non-Timeliness coverage of patrol officer, there's a sudden fall in temperature, and the air precipitation of dissolving in oil enters Buchholz relay and causes grave gas protection act to jump car; affect the normal work of transformer, impact is powered normally.
Chinese patent publication No. is: CN 103830862 A, patent name is " transformer pouring nitrogen type fire-fighting protection device ", comprise installation for transformer, transformer body, exhaust oil tank and nitrogen storage cabinet, described installation for transformer connects cut-off valve and Buchholz relay successively by pipeline, Buchholz relay is connected with transformer body by pipeline, the top of transformer body is provided with fire detector, the right side of transformer body is provided with exhaust oil tank, exhaust oil tank connects explosion decompression storehouse and transformer body respectively by pipeline, explosion decompression storehouse is connected with transformer body by pipeline, transformer body is inner arranges Loading voltage regulator near top end, Loading voltage regulator connects nitrogen storage tank by pipeline, nitrogen storage tank by pipeline respectively with transformer body and be vented oil tank.This device realizes flame failure protection transformer by injection nitrogen; the signal of Buchholz relay and fire detector is received by control system; nitrogen storage tank starts immediately and realizes flame failure protection; operating process is complicated; the protective effect of transformer can not be carried out in real time, add the production cost of product protection simultaneously.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of transformer body protective device, improves installation effectiveness, alleviate the labour intensity of workmen.
Its technical scheme is: comprise transformer body, explosion stack, oil conservator, oil pipe, Buchholz relay, discharge, dehydrating breather, bushing shell for transformer, transformer body is provided with bushing shell for transformer, the top of transformer body connects explosion stack, the end of described explosion stack is provided with the tube connector being communicated with oil conservator, oil conservator is by oil pipe connection transformer body, described oil pipe is provided with Buchholz relay, the inside of described oil conservator connects discharge, the end of described discharge connects dehydrating breather, described explosion stack is bending tube, the bottom of explosion stack is provided with venthole, venthole is communicated with oil conservator.
The bending angle of above-mentioned bending tube is 90-120 degree, reduces the pressure of explosion stack inside.
Above-mentioned dehydrating breather inside is provided with the dividing plate of bending, and described diaphragm internal is provided with Silica gel activated Attraction block.
The beneficial effects of the utility model are: the labor safety that ensure that personnel; prevent air accumulation in Buchholz relay; preventing the air precipitation of dissolving in oil from entering Buchholz relay causes grave gas protection act to jump car, ensures the normal work of transformer, provides normal supply of electric power.
