Abstract
A power transformer comprises an oil tank and a transformer body immersed in the oil tank. Three high-voltage conductive terminals and three low-voltage conductive terminals are arranged on the top of the transformer body. An oil injection pipe is arranged on a tank cover of the oil tank and provided with a pressure relief valve, an oil level meter is arranged at the lower right corner of the oil tank, and an oil tank valve and an oil discharge plug are arranged at the bottom of the oil tank. The power transformer is good in tightness and safety, and the oil tank is not easy to deform.
Description
Technical field:
The utility model relates to a kind of power transformer.
Background technology:
Transformer is the visual plant in power transmission and transformation system, and the oil seepage phenomena of oil-immersed power transformer is long-standing problem.Because existing oil-immersed power transformer mostly adopts floated oil level indicator, it is to use glass tube that the liquid level of its oil level indicator shows, because the mechanical strength of glass tube is low, cracky so sealing property is bad, easily causes rain leakage to fuel tank, reduce the dielectric strength of oil, and the transformer oil of transformer when operation inside can expanded by heating, and fuel tank is produced larger pressure, easily causes the fuel tank distortion.
The utility model content:
The technical problem that the utility model solves is to provide a kind of power transformer, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of power transformer, comprise fuel tank and the device body that is immersed in fuel tank internal, described device body top is provided with three high-voltage conducting wires terminals and three primary cable terminals, the case lid of described fuel tank is provided with oil fuel tube, oil fuel tube is provided with pressure relief valve, the lower right corner of described fuel tank is provided with oil level indicator, and described fuel tank bottom is provided with fuel tank valve and bleeder plug.
Described oil level indicator is high by a kind of mechanical strength, cracky not, and the transparent material that corrosion resistance is strong is made.
Described fuel tank bottom also is provided with earth stud.
Beneficial effect:
The utility model arranges oil level indicator, its oil level indicator is high by a kind of mechanical strength, cracky not, the transparent material that corrosion resistance is strong is made, removed from oil level indicator leakage of oil, and automatically regulate internal pressure in transformer work due to pressure relief valve, and guaranteed that fuel tank is not yielding, guaranteed the security performance of transformer.
Description of drawings:
Fig. 1 is a kind of front view of power transformer
In figure: 1-fuel tank, 2-case lid, 3-high-voltage conducting wires terminal, 4-primary cable terminal, 5-oil fuel tube, 6-oil sample valve, 7-bleeder plug, 8-oil level indicator.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of power transformer, comprise fuel tank 1 and the device body that is immersed in fuel tank internal, it is characterized in that, described device body top is provided with three high-voltage conducting wires terminals 3 and three primary cable terminals 4, and the case lid 2 of described fuel tank 1 is provided with oil fuel tube 5, and described oil fuel tube 5 is provided with pressure relief valve, the lower right corner of described fuel tank 1 is provided with oil level indicator 8, and described fuel tank 1 bottom is provided with oil sample valve 6 and bleeder plug 7.
The utility model arranges oil level indicator, its oil level indicator is high by mechanical strength, cracky not, the transparent material that corrosion resistance is strong is made, removed the leakage of oil in oil level hole from, and automatically regulated the internal pressure that transformer oil causes in transformer work by pressure relief valve, guaranteed that fuel tank is not yielding.Guaranteed the security performance of transformer.
above demonstration and described sill principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, that describes in above-described embodiment and specification just illustrates principle of the present utility model, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall in claimed the utility model scope, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
