Abstract
The utility model relates to a novel sealing sleeve for the joint of a transformer and an enclosed busbar. The novel sealing sleeve is arranged between the transformer and an enclosed busbar shell to be connected with the transformer and the enclosed busbar shell, and comprises a movable sleeve, a lifting base located inside the movable sleeve, a first flange and a second flange; the movable sleeve is located on the lower portion of the enclosed busbar shell to be connected with the enclosed busbar shell, the movable sleeve can move up and down along the axis of the lifting base, the first flange is located between the enclosed busbar shell and the movable sleeve to achieve the sealing effect on the enclosed busbar shell and the movable sleeve, and the second flange is located between the movable sleeve and the lifting base to achieve the sealing effect on the movable sleeve and the lifting base. By means of the technical scheme, the movable sleeve is in pressing sealing with the upper sealing flange and the lower sealing flange through an upper fixing armour clamp and a lower fixing armour clamp, line contact is adopted for the position, and sealing is reliable. In addition, the movable sleeve can move up and down along the axis of the lifting base, and the requirements of device installation, device overhauling and device maintaining are met.
Description
Technical field
The utility model relates to a kind of sealing shroud, particularly a kind of transformer and the female New type gland cover being connected of envelope.
Background technology
Nowadays, large capacity oil-filled transformer and enclosed busbar junction generally adopt rubber sleeve sealing, thereby reduce a sleeve pipe external insulation to prevent that rainwater from entering in bushing shell for transformer rising seat, avoid occurring the accident such as flashover, contact.But due to rubber sleeve sealing means, and aging along with rubber sleeve, due to the impact of the factor such as sunshine and ozone, this rubber telescopic is aging and cracking easily, brings hidden danger to the safe operation of bus.Unavoidable phenomenons such as seat ponding that occur raising just in poorly sealed situation, also find that there is sleeve pipe that power plant occurs that transformer is connected with envelope mother and cause the appearance of ground fault because of ponding.For this reason, be necessary sealing gum cover to transform, the seat seeping phenomenon of thoroughly stopping to raise occurs.
Utility model content
The technical problems to be solved in the utility model is that a kind of transformer and the female New type gland cover being connected of envelope of better tightness is provided.
For this reason, the technical solution of the utility model is:
A kind of transformer and the female New type gland cover being connected of envelope, it is arranged in the middle of transformer and the female shell 2 of envelope and is attached thereto, comprise a quill 1, described quill 1 is positioned at the bottom of the female shell 2 of described envelope and is attached thereto, also comprise, one is positioned at the rising seat 3 of described quill 1 inside, and described quill 1 can move up and down along the described axis that raises seat 3; The first flange 4, between the female shell 2 of described envelope and described quill 1 and it is sealed; The second flange 5, between described quill 1 and described rising seat 3 and it is sealed; The first fixing gold utensil 7, connects and fixes described quill 1, seals female shell 2 and the first flange 4; The second fixing gold utensil 8, connects and fixes described rising 3 and the second flange 5.
Further, the described seat 3 that raises is a rising seat that can raise described quill 3.
Further, described raise seat 3 bottom higher than described quill 4 bottom.In this further technical scheme, the seat 3 that raises is inner and higher than it bottom in quill, the possibility of thoroughly avoiding rainwater to enter.
Further, between described quill 1 and described rising seat 3, be also connected with an extensible member 6.
Further, described extensible member 6 is a L shaped rubber extensible member.In this further technical scheme, between quill 1 and rising seat 3, adopt L shaped rubber extensible member to be connected, meet the needs such as alignment error adjustment, shock insulation, temperature-compensating.
Further, described quill 1 is an aluminium matter sleeve.In this further technical scheme, adopt aluminium matter quill 1 to replace rubber telescopic, avoid causing because rubber telescopic is aging rainwater to enter the possibility of the female shell 2 of envelope.
The utlity model has following beneficial effect: in the technical solution of the utility model, quill is by upper and lower two fixing gold utensils and the sealing of upper-lower seal flange screw, and this place adopts line contact, and sealing is reliable; In addition, quill can move up and down along the seat axis that raises, and meets equipment installation, Problem needs.
Accompanying drawing explanation
Fig. 1 is the partial sectional view in a kind of transformer of the utility model and a preferred embodiment that seals female New type gland cover being connected.
Embodiment
As shown in Figure 1, in a preferred embodiment, a kind of transformer and the female New type gland cover being connected of envelope, it is arranged in the middle of transformer and the female shell 2 of envelope and is attached thereto, comprise a quill 1, quill 1 is positioned at the bottom of the female shell 2 of envelope and is attached thereto, and characterized by further comprising, one is positioned at the rising seat 3 of quill 1 inside, and quill 1 can move up and down along the axis of the seat 3 that raises; The first flange 4, is sealing between female shell 2 and quill 1 and it is being sealed; The second flange 5, quill 1 and raise seat 3 between and it is sealed; The first fixing gold utensil 7, connects and fixing quill 1, seals female shell 2 and the first flange 4; The second fixing gold utensil 8, connects and fix raise seat 3 and the second flange 5, and rising 3 is a rising seat that can raise quill 3.
Continue referring to Fig. 1, in the preferred embodiment, the seat 3 that raises bottom higher than quill 4 bottom, certainly, in other execution mode, its position can be done adjustment by a small margin up and down.In when work, because this rising seat 3 is inner and higher than it bottom in quill, the possibility that can thoroughly avoid rainwater to enter; Between quill 1 and rising seat 3, be also connected with an extensible member 6, this extensible member 6 can be a spring assembly, certainly, and in other preferred embodiment, also can be a spring part, also can be a rubber parts, further, extensible member 6 is a L shaped rubber extensible member, this embodiment selects this L-type rubber extensible member, in the course of the work, between quill 1 and rising seat 3, adopt L shaped rubber extensible member to be connected, meet the needs such as alignment error adjustment, shock insulation, temperature-compensating.
In addition, in the preferred embodiment,, quill 1 is an aluminium matter sleeve, in the course of the work, by, adopt aluminium matter quill 1 to replace rubber telescopic, avoid causing because rubber telescopic is aging rainwater to enter the possibility of the female shell 2 of envelope.
In the real course of work, whole retrofit work exists several important technical risks, the one, workmen causes equipment loss, comprise that the damage of bushing shell for transformer porcelain vase, welding slag scorch equipment, the bad live metal sleeve run duration overtemperatures etc. that cause of ground connection such as the cable at porcelain vase and transformer top, the risk that may occur for these, following several work have been done by electric branch: bushing shell for transformer is adopted to thicker rubber cushion parcel, sealing, isolated welding slag, the instrument that also can prevent drops and injures equipment by a crashing object; By other work reasonable arrangements on transformer body, reduce forked working; Increase earthing of casing line etc., these measures successfully avoid occurring that intending malignant event occurs, and guarantee that whole transformation project completes smoothly.Quill of the present utility model is by upper and lower two fixing gold utensils and the sealing of upper-lower seal flange screw, and this place adopts line contact, and sealing is reliable; In addition, quill can move up and down along the seat axis that raises, and meets equipment installation, Problem needs.
