Abstract
The utility model discloses a plastic insulator. A screw rod which is sequentially provided with a conical column, an upper screw cap 1, an upper screw cap 2 and an upper washer passes through a hole on an oil tank cover plate of a transformer; after the lower end of the screw rod penetrates through a concave column and a lower washer, the screw rod is fixed on the hole of the oil tank cover plate of the transformer by a lower screw cap 1 and a lower screw cap 2, thus the conical column and the concave column clamp the oil tank cover plate hole of the transformer, and play a role of fixing and sealing; the screw rod passes through a hole at the middle of the conical column and the concave column; high-voltage electricity is output from the screw rod, the screw rod is separated from the oil tank cover plate by the conical column and the concave column, thus the high-voltage electricity is output safely.
Description
Technical field
The utility model relates to a kind of insulator made from plastic, can safely and effectively the high-tension electricity in the oil-immersed type transformer be drawn smoothly.
Background technology
At present, for solving oil-immersed type transformer lead-out wire Insulation Problems, adopt the ceramic insulation insulating sublayer usually; The withstand voltage height of ceramic insulator; But damage easily, little to some use amounts especially, voltage adopts the ceramic material cost high less than the insulator of 5KV; Difficulty is big, for the leakage that prevents oil must have the sealing device sealing.
Summary of the invention
In order to overcome existing oil-immersed type transformer lead-out wire Insulation Problems, the utility model provides a kind of insulator made from plastic, and this insulator made from plastic is not only simple in structure, cost is low, easily manufactured, and the self seal better performances.
The utility model solves the technical scheme that its technical problem adopted: will be installed with tapered pole, upper cap nut 1, upper cap nut 2, upper gasket, screw rod successively and pass the hole on the transformer oil cover plate; Concave column, lower gasket are passed in the lower end; Nut 1 is fixed on the hole of transformer oil cover plate with following nut 2 under using, and makes tapered pole and concave column clamp the oil tank of transformer cover board hole, plays fixing and sealing function; Screw rod passes the hole in the middle of tapered pole and the concave column; High-tension electricity is exported from screw rod, and screw rod is isolated by tapered pole and concave column and tank cover, thereby high-voltage safety is exported.
The beneficial effect of the utility model is, insulator made from plastic can be safely with high-tension electricity output, and the tapered pole of plastic production and concave column are clamped fuel tank cap and had good sealing property, do not need sealing device.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
