Description

Bushing shell for transformer oil impregnate service kit
Technical field
The present invention relates to a kind of Repair of Transformer instrument, relate in particular a kind of oil-filled transformer sleeve pipe oil impregnate service kit.
Background technology
After oil-filled transformer long-time running, overload or short trouble, the defects such as sleeve pipe nut and conducting rod adhesion, conducting rod silk mouth and oil sealing cushion rubber burn out appear, thereby cause that the breakage of sleeve pipe porcelain vase, loosened screw landing, oil sealing cushion rubber cross cause thermal damage, cause Leakage in Transformer.Under traditional mode, change in the conventional instrument of cushion rubber use, conducting rod can rotate together along with nut when getting nut, conducting rod can't be fixed, thereby have to adopt the way of suspended core, employ forklift or crane, repair time is long, manpower and materials consumption is large, and the potential safety hazard increase, is unfavorable for carrying out smoothly of site operation.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of bushing shell for transformer oil impregnate service kit is provided, the problem that while having solved bushing shell for transformer oil impregnate maintenance in the past, cost is high, consumption is large and maintenance is complicated.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: bushing shell for transformer oil impregnate service kit, comprise sleeve, clamp, fixture block and clamping bar, and clamp comprise clamp, be provided with cavity in clamp, described clamping bar passes clamp fixture block is fixed in cavity.This programme is when application, cavity is passed conducting rod, put into fixture block in cavity, and promote fixture block by clamping bar conducting rod is tightened, can prevent that conducting rod from rotating, after the conducting rod chucking, screw tap will be sandwiched in sleeve, thereby can recover the conducting rod silking to the conducting rod tapping, to solve the problem of loosened screw landing; Due to sleeve pipe nut and conducting rod adhesion, conducting rod can prevent conducting rod with cap rotation when clamping is become flexible nut afterwards, be convenient for changing oil sealing cushion rubber and damaged sleeve pipe porcelain vase; This programme is simple in structure, and size is little, carries, easy to operate, can effectively improve bushing shell for transformer oil impregnate overhaul efficiency, avoid the mode of taking suspended core to process because of the sleeve pipe seepage, reduce the input of human and material resources and financial resources, reduced Field Force's labour intensity, practical.
Further, described fixture block is provided with the shrinkage pool that can stretch into clamping bar.Because fixture block is to promote conducting rod is tightened by clamping bar, in order to prevent that fixture block from sliding after chucking, establish shrinkage pool in the place that fixture block contacts with clamping bar, the clamping bar front end stretches into shrinkage pool, can prevent effectively that clamping bar and fixture block from sliding mutually in the process that clamping bar promotes; Shrinkage pool in this programme can be also groove, screwed hole, but considers structure and effect, and shrinkage pool is best, so this programme is selected the shrinkage pool structure.
Further, described fixture block is parallel in two vertical planes of clamping bar and is provided with tongue, and described cavity is provided with the groove that matches with tongue in the side corresponding with tongue, form fixture block slides along groove in cavity bascule.When tightening conducting rod, steady in order to keep fixture block due to fixture block, prevent that fixture block from rotating with conducting rod, simultaneously for easy to carry, so fixture block and the clamp mechanism by sliding tray is coupled together, and fixture block just can only slide and can not rotate in sliding tray like this, has improved chucking intensity.
Further, described sleeve comprises loop bar and the scroll chuck that is connected with loop bar one end, scroll chuck is provided with three claws, but described scroll chuck periphery also is provided with the adjustment screw that the control card pawl moves radially at scroll chuck, and the chucking face of described claw is provided with screw thread.In order to make sleeve to carry out tapping to the conducting rod screw mandrel of different size; so barrel forward end and screw tap are adopted the scroll chuck chucking; can arbitrarily adjust the chucking size; simultaneously at the chucking face of claw, establish screw thread and not only can increase chucking intensity; prevent claw and screw mandrel relative sliding, the screw thread of protection screw mandrel that can also be fabulous.
Further, described loop bar is hollow rod body.Because the screw mandrel length of conducting rod is longer, in order to facilitate tapping, so loop bar is hollow rod body, the part of screw mandrel tapping can be stretched out by loop bar, can not affect tapping, and is practical.
Further, described loop bar is provided with through hole on the periphery away from scroll chuck one end.Need to use larger power during due to tapping, hold loop bar during tapping sometimes and can not well exert all one's strength,, so can insert straight-bar in through hole, by pulling straight-bar, rotate the loop bar tapping, the tapping difficulty and the physical demands that reduce a staff, improve tapping efficiency.
Further, described clamp are connected with at the clamp lateral surface bar of shaking hands, and described clamp is provided with through hole in the side relative with the bar of shaking hands, and described clamping bar passes through hole fixture block is fixed.Clamp is after the chucking conducting rod, thereby the hand-holdable bar of shaking hands of staff keeps clamp to maintain static, and by through hole, can well locate, and prevents that clamping bar from sliding.
Further, described clamp is provided with the arc-shaped slot I in the side that cavity is positioned at bar one side of shaking hands, and the side that described fixture block is corresponding with arc-shaped slot is provided with the arc-shaped slot II, and arc-shaped slot II and arc-shaped slot I are equipped with screw thread.In order to strengthen tightening the screw mandrel tooth line of effect and protection conducting rod,, so in the place of clamp and fixture block chucking conducting rod, draw-in groove is set, and establish the screw thread with conducting rod screw mandrel coupling, can well protect the tooth line of conducting rod and clamp effectively, clamp firmly.
Further, described through hole is provided with screw thread, and described clamping bar is provided with the screw rod with the through hole whorl coupling, and screw rod is connected with screw rod and shakes hands.Clamping bar needs afterburning setting fixture block can be located after clamping fixture block, in order to reduce the use difficulty, so at through hole, establish screw thread, clamping bar is established the screw rod with the through hole whorl coupling, the screw rod connecting screw rod is shaken hands, like this, and when the staff clamps fixture block at needs, only need hold the screw rod rotation of shaking hands, coordinate fixture block is screwed with screw rod by through hole whorl, screw rod can be locked by screw thread after screwing simultaneously, need not to continue to add external force, simple in structure, easy to operate; Screw rod in this programme surface of shaking hands can be established annular knurl and be used for to be increased the frictional force of shaking hands with hand, the consumption that reduces a staff.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is simple in structure, and size is little, and is easy to operate, is easy to carry.
2, cost of the present invention is low, can repeatedly use, and is effective.
3, the present invention effectively improves bushing shell for transformer oil impregnate overhaul efficiency, has simplified bushing shell for transformer oil impregnate maintenance step, and is practical.
