Abstract
The utility model relates to high-pressure side all insulation distribution transformers, including fuel tank (4) and it is immersed in the internal body of fuel tank (4), the body is equipped with high-voltage conducting wires terminal (2) and primary cable terminal (3) for connecting extraneous cable, the high-voltage conducting wires terminal is European casing, one end of the European casing passes through outside oil tank wall to fuel tank, and the other end is located at the inside of fuel tank.The utility model has the advantages that: realize on high-tension side hermetically sealed, all insulation；After end installation, the degree of protection at high pressure connection can achieve IP67, reduces external environment, such as the influence of dust, moisture to product, to greatly improve Supply Security and reliability, while can also reduce later maintenance cost.
Description
Technical field
The utility model relates to a kind of high-pressure side all insulation distribution transformers.
Background technique
Currently, the oil-immersed transformer of 10KV field of power distribution application is the insulator tubular type lead dress that high-pressure side is air insulation
It sets, using such gage system, high-pressure side uses air insulation, firstly, insulation is highly prone to the influence of external environment, such as air
Pollution level, dust, air humidity etc. are made secondly, high-voltage charged body is exposed by the way of air insulation to operation and maintenance
At some potential safety problems, air insulation is used again, is also easy to produce shock hazard, and operational safety hidden danger is prominent.It needs periodically clear
Harmful dust accumulation on porcelain bushing shell is managed, operation expense is increased.
Summary of the invention
To overcome the shortcomings of existing technologies, the utility model provides a kind of high-pressure side all insulation distribution transformer, this is practical
Novel technical solution is:
High-pressure side all insulation distribution transformer including fuel tank (4) and is immersed in the internal body of fuel tank (4), the body
It is equipped with the high-voltage conducting wires terminal (2) and primary cable terminal (3) for connecting extraneous cable, the high-voltage conducting wires terminal is
One end of European casing, the European casing passes through outside oil tank wall to fuel tank, and the other end is located at the inside of fuel tank, the European casing
One end in fuel tank is equipped with T2 red copper bar, the European casing outside fuel tank and to pour epoxy resin between fuel tank exhausted
Edge layer is attached between the European casing and cable using the European end of shield type.
Oil level indicator (1) is installed on the fuel tank.
The European casing is fixedly mounted on body by fixed plate.
The utility model has the advantages that: realize on high-tension side hermetically sealed, all insulation；After end installation, at high pressure connection
Degree of protection can achieve IP67, external environment, such as the influence of dust, moisture to product are reduced, to greatly improve confession
Electric safety and reliability, while can also reduce later maintenance cost.
Detailed description of the invention
Fig. 1 is the agent structure schematic diagram of the utility model.
Specific embodiment
Further describe the utility model combined with specific embodiments below, the advantages of the utility model and feature will be with
Description and it is apparent.But examples are merely exemplary for these, does not constitute any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under the spirit and scope without departing from the utility model
The details and form of art scheme are modified or are replaced, but these modifications and replacement each fall within the protection scope of the utility model
It is interior.
Referring to Fig. 1, the utility model relates to a kind of high-pressure side all insulation distribution transformer, including fuel tank 4 and it is immersed in oil
Body inside case 4, the body are equipped with high-voltage conducting wires terminal 2 and primary cable terminal 3 for connecting extraneous cable, institute
The high-voltage conducting wires terminal stated is European casing, and one end of the European casing passes through outside oil tank wall to fuel tank 4, and the other end is located at oil
The inside of case 4, one end which is located in fuel tank are equipped with T2 red copper bar, the European casing outside fuel tank and oil
Epoxy resin insulating layers are poured between case 4, are attached between the European casing and cable using the European end of shield type.
Oil level indicator 1 is installed on the fuel tank.
The thread guide devices of the utility model use European casing, and European casing is connected by bolt with high-voltage winding, European
Casing is fixed on body using pressing plate, is all made of cold joint mode, replacement convenient to overhaul.
The European casing can be used cooperatively with European shielding type cable connector, to realize the complete close of high voltage side of transformer
Envelope, all insulation.It is preferably minimized influence of the environment to transformer；High voltage side of transformer is handled using tangible end all insulation
Afterwards, the person can directly contact high-pressure side, will not cause electric shock accidents, therefore greatly improve Supply Security, reduce security risk.
