Description
Technical field
The utility model belongs to electrical equipment technical field, specifically a kind of transformer water-tight device.
Background technology
Bushing shell for transformer is the external primary insulation device of transformer tank, and its effect makes to insulate between lead-in wire and between lead-in wire and transformer case, plays anchor leg effect simultaneously.The insulation fault that transformer causes due to watered and wetting constantly occurs, and accounts for 20% of insulation fault.And the one of the main reasons of watered and wetting is exactly: the junction of insulating sleeve top lead nose is naked to be exposed on the external, and bushing for transformer top seal is bad, moisture enters in insulating sleeve along lead-in wire, causes breakdown accident.The water-tight of visible thimble assembly normally runs transformer and plays vital effect.
Summary of the invention
Technical problem to be solved in the utility model is, provides one to make insulating sleeve and lead-in wire junction good waterproof performance, thus ensures the transformer water-tight device that transformer normally runs.
Transformer water-tight device of the present utility model, comprises the insulating sleeve being arranged on transformer tank external body, the conductive pole being positioned at insulating sleeve inner chamber, and the terminals at described conductive pole top stretch out insulating sleeve; The top of described insulating sleeve is provided with a waterproof cover, and the top of described conductive pole is arranged in the inner chamber of described waterproof cover; The sidewall of described waterproof cover has an incoming line, for lead-in wire through, be connected on conductive pole.
The top of described waterproof cover is provided with a through hole, the top of described conductive pole is provided with one section of threaded rod closed with the matching size of waterproof cover top through hole, described threaded rod through waterproof cover top through hole and by a mounting nuts, waterproof cover is pressed on the end face of insulating sleeve.
The top of described conductive pole is provided with one section of thread segment, described thread segment being provided with two for compressing the clamp nut of lead-in wire line nose, for clamping the line nose of lead-in wire, being installed on conductive pole by lead-in wire.
Between described mounting nuts and waterproof cover end face, between two clamp nuts and be respectively arranged with sealing gasket between waterproof cover and the end face of insulating sleeve, the sealing property of intensifier.
Described incoming line comprise one section with the water-inlet-proof pipe of waterproof cover sidewalls orthogonal, prevent the rainwater tilted from entering waterproof cover inner chamber from incoming line, affect sealing property.
The outer setting of described insulating sleeve has cluster parachute, the surface of the described cluster parachute the superiors is provided with multiple gutters of radial distribution.
Apparatus structure of the present utility model is simple, good water-proof effect.
