The utility model discloses a kind of explosion-proof transformer sleeve pipe, including center conductor, the core body being set in outside the center conductor and the flange being fixed on outside the core body, the core body outer sheath is provided with umbrella cover, described umbrella cover one end leans the flange, the umbrella cover other end has leaned end cap, side of the end cap away from the umbrella cover is provided with pressing plate, spring is provided between the end cap and the pressing plate, side of the pressing plate away from the end cap is provided with the fastener coordinated with the screw thread on the core body.As long as fastener to be screwed to when installing umbrella cover the bottom of thread on core body using the structure, thrust is controlled by spring, so that umbrella cover is easy for installation, can not only be ensured sealing and can be prevented umbrella cover from bursting.
Description
Technical field
The utility model belongs to bushing shell for transformer technical field, specifically a kind of explosion-proof transformer sleeve pipe.
Background technology
Bushing shell for transformer is the primary insulation device outside transformer tank, and the lead-out wire of Transformer Winding has to pass through insulation sleeve
Pipe, make to insulate between lead-out wire and between lead-out wire and transformer case, while play fixation lead-out wire.
The umbrella cover both ends difference flange and end cap, existing flange and end cap of existing bushing shell for transformer pass through
Threaded connection, when installing umbrella cover, flange is fixed, is then charged into umbrella cover, the end cap of the other end is by screw thread by umbrella cover
Jam-packed is between end cap and flange, in order to ensure that sealing end cap must have enough thrusts between umbrella cover, and thrust
The dynamic regulation of pure armrest is unmanageable, too loose to be difficult to ensure that sealing, too tight umbrella cover to be caused to burst.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of explosion-proof transformer sleeve pipe, this kind of explosion-proof transformer sleeve pipe
The thrust between umbrella cover and end cap controls by spring when mounted, it is not necessary to adjusts the pressure between end cap and umbrella cover manually
Clamp force, so as to ensure that it is quick-fried that thrust and can enough prevents that umbrella cover from being pressed.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of explosion-proof transformation
Device sleeve pipe, including center conductor, the core body being set in outside the center conductor and the flange being fixed on outside the core body, it is described
Core body outer sheath is provided with umbrella cover, and described umbrella cover one end leans the flange, and the umbrella cover other end has leaned end cap, the end cap
Side away from the umbrella cover is provided with pressing plate, spring is provided between the end cap and the pressing plate, the pressing plate is away from institute
The side for stating end cap is provided with the fastener coordinated with the screw thread on the core body.As long as will when installing umbrella cover using the structure
Fastener is screwed to the bottom of thread on core body, and thrust is controlled by spring, so that umbrella cover is easy for installation, not only
Sealing can be ensured and can prevent umbrella cover from bursting.
In above-mentioned technical proposal, it is preferred that spring mounting groove is provided with the end cap, the spring is arranged at the bullet
In spring mounting groove.Spring is carried out using the structure spacing.
In above-mentioned technical proposal, it is preferred that the umbrella cover both ends are provided with sealing ring.Umbrella cover two is caused using the structure
The sealing at end improves.
In above-mentioned technical proposal, it is preferred that be provided with insulating paste in the gap between the umbrella cover and the core body.Using
The structure causes insulating properties to improve.
In above-mentioned technical proposal, it is preferred that be provided with measurement terminal on the flange.Set measurement terminal can be in transformation
It is convenient after device sleeve pipe installation that its performance is tested.
In above-mentioned technical proposal, it is preferred that be provided with resin glue between the gap of the flange and the core body.
The utility model compared with prior art, has the advantages that：As long as using the structure when installing umbrella cover
Bottom of thread fastener being screwed on core body, thrust is controlled by spring, so that umbrella cover is easy for installation, no
Sealing can only be ensured and can prevent umbrella cover from bursting.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is Fig. 1 partial enlarged drawing.
Embodiment
