Description
The technical field is as follows:
the utility model relates to an insulating oilpaper condenser transformer bushing oil mesostructure under glass steel.
Background art:
the power industry plays an important role in national economy, and many aspects of modern industry, agriculture, traffic, national defense and people's life cannot be isolated from electricity. The power transmission and transformation equipment is an important component of power equipment, and powerful electric energy generated by a power station can be transmitted to each user only through the power transmission and transformation equipment. The mutual inductor is an indispensable important device in the power transmission line and is used for measuring and protecting the power transmission and transformation device.
The transformer bushing oil is provided with a grounding position and a mutual inductor which are matched with each other in a certain length, the structure of the grounding position is shown in figure 2, the grounding position generally uses a cylinder made of an aluminum alloy material, the upper end of the cylinder is connected and sealed with a mounting flange 1, the lower end of the cylinder is connected and sealed with a lower insulation 2, and the lower insulation 2 can be made of porcelain or epoxy materials.
This kind of structure is with high costs, and sealed probably became invalid between earthing position and lower insulation 2, caused the sleeve pipe oil leak, and my company made lower insulation with glass steel before, establish semiconductor material in the outside and form equipotential and replace the aluminium section of thick bamboo, nevertheless lead to the inside electric field of sleeve pipe inhomogeneous easily, easily produce acetylene after power frequency is withstand voltage.
The oil paper condenser bushing can not avoid forming impurities in oil in the production process, the impurities are gathered at the tail part of the bushing after long-term operation, and the tail part of the bushing is the place with the largest electric field, so that the bushing fault is easily caused.
The invention content is as follows:
the utility model relates to a solve the problem that above-mentioned prior art exists and provide an insulating oiled paper condenser transformer bushing oil mesostructure under the glass steel.
The utility model discloses the technical scheme who adopts has: the mounting flange and the base are respectively mounted on the upper side and the lower side of the lower insulation of the glass fiber reinforced plastic, the lower insulation of the glass fiber reinforced plastic comprises a grounding part and an insulating part, a carbon fiber or semiconductor material is arranged on the inner surface of the grounding part, and the carbon fiber or semiconductor material and the grounding part are solidified and molded together and are in short circuit with the mounting flange; the bottom of the insulating part is connected with the base in a gluing and sealing manner, and a dirt collecting groove is formed at the tail part of the transformer bushing.
The utility model discloses following beneficial effect has:
the mode that the glass fiber reinforced plastic lower insulation inner surface is provided with the carbon fiber or the semiconductor material is used for replacing the conventional aluminum alloy grounding cylinder, so that the cost is reduced, the manufacturing is simple, the electric field is uniform, and the sealing is more reliable. The lower end of the glass fiber reinforced plastic insulator and the base are glued to form a dirt collecting groove, so that the process sanitation inside the sleeve can be guaranteed, and the sleeve is safe and reliable to operate.
Description of the drawings:
fig. 1 is a structural diagram of the present invention.
Fig. 2 is a structural view of a conventional structure.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the utility model relates to a structure in insulating oiled paper condenser transformer bushing oil under glass steel, including mounting flange 1, insulating 2, base 3 under the glass steel, wherein the insulating ground connection part 21 and insulating part 22 that divide into under the glass steel.
The mounting flange 1 and the glass fiber reinforced plastic lower insulation 2 are glued to form a whole and sealed, the glass fiber reinforced plastic lower insulation grounding part 21, namely a part for mounting the current transformer, is provided with carbon fiber or semiconductor materials 4 on the inner surface of the glass fiber reinforced plastic lower insulation 2, and is in short circuit with the mounting flange 1. 2 bottoms of insulation and 3 cementing sealing connection of base under the glass steel form an equipotential dirty groove 5 of collection at the sleeve pipe afterbody, also can not lead to discharging if there is impurity in the oil, safer to the product.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
