Abstract
The utility model discloses an insulating bush for a transformer hoist seat, which is characterized by comprising an insulating cylinder, a square ring and bakelite bolts; a circle of square ring protecting plate used for being overlapped with the insulating cylinder is arranged at the root of the square ring; the insulating cylinder, the square ring and the square ring protecting plate adopt insulating structures made of insulating carboards or epoxide resin; the insulating cylinder and the square ring are respectively fixed in corresponding positions in the hoist seat through the bakelite bolts; the square ring is vertically positioned on one side of the middle of the insulating cylinder; and the insulating cylinder is adhered together with the square ring protecting plate through insulating cement. The insulating bush has the benefits of simple structure and reliable insulating property, and is put in the transformer hoist seat, so that the creepage distance of a lead wire and a sleeve to the hoist seat is increased, and the insulating strength is improved. The insulating bush is mainly applied to power transformers at more than 110 kV voltage class.
Description
(1) technical field
The utility model belongs to transformer accessory, particularly a kind of power transformer enclosure insulation lining.
(2) background technology
Present stage, do not find and the design's identical in structure insulation lining.
(3) summary of the invention
The utility model provides a kind of simple in structure, the reliable power transformer enclosure of insulation property insulation lining in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Power transformer enclosure of the present utility model insulation lining, its special character is: comprise insulating cylinder, square ring, bakelite bolt, the root of square ring is provided with one and encloses the square ring backplate that is used for the insulating cylinder overlap joint, insulating cylinder, square ring, square ring backplate be the insulation system for being made by insulating board or epoxy resin all, by the bakelite bolt insulating cylinder and square ring are separately fixed at the interior relevant position of seat that raises, square ring vertically is positioned at middle part one side of insulating cylinder, and insulating cylinder and square ring backplate bond together by insulating cement.
The beneficial effects of the utility model are, and are simple in structure, insulation property are reliable, the utility model is placed in the power transformer enclosure and uses, and increased lead-in wire, the sleeve pipe creepage distance to the seat that raises, and improved dielectric strength.Be mainly used in the power transformer of the above electric pressure of 110kV.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
Fig. 1 is overall structure figure, and Fig. 2 is the right view of insulating cylinder, and Fig. 3 is the front view of insulating cylinder, and Fig. 4 is the vertical view of Fig. 2, and Fig. 5 is the right view of square ring, and Fig. 6 is the front view of square ring, and Fig. 7 is the vertical view of Fig. 5.
Among the figure, 1 insulating cylinder, 2 square rings, 3 bakelite bolts, 4 square ring backplates, 5 rising seats.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Power transformer enclosure of the present utility model insulation lining, comprise insulating cylinder 1, square ring 2, bakelite bolt 3, the root of square ring is provided with one and encloses the square ring backplate 4 that is used for the insulating cylinder overlap joint, insulating cylinder 1, square ring 2, square ring backplate 3 be the insulation system for being made by insulating board or epoxy resin all, by the bakelite bolt insulating cylinder 1 and square ring 2 are separately fixed at relevant position in the seat 5 that raises, square ring vertically is positioned at middle part one side of insulating cylinder, and insulating cylinder and square ring backplate 3 bond together by insulating cement.
The utility model is placed in the power transformer enclosure and uses, and to increase lead-in wire, the sleeve pipe creepage distance to the seat that raises, improves dielectric strength.
When the utility model is installed, with the bakelite bolt insulating cylinder 1 being fixed on the seat 5 that raises earlier, with the bakelite bolt moulding square ring 2 being fixed on the seat 5 that raises, is the overlap of insulating cylinder and moulding square ring that square ring backplate 3 usefulness insulating cements bond together then.
