Description
Technical field
Design and manufacture, installation and maintenance field the invention belongs to cable accessory, and in particular to a kind of cable accessory branch refers to
Set includes the online restorative procedure after insulating jacket layer breakage.
Background technology
With automation and information-based high development, the covering surface of power transmission network is increasing, also to power grid dilatation and more
The reliability design newly regenerated proposes increasingly higher demands, it may be said that enters six western trellis codes（6σ）Quality control when
In generation, the structure design of tradition grid equipment and its cable accessory, reliability design and installation service mode also lagged behind this in the past
Kind requires.
For example, found in the installation of cable accessory and maintenance process, cable accessory branch fingerstall that factory makes and absolutely
Edge protecting pipe finished product is undergoing carrying, installation, is dismantling, after misphase reversing of position, or even when neighbouring accident or power grid failure itself,
The frequency that fingerstall and sheath at cable branch are damaged is very high.Although the electric stress control main body of impaired cable accessory is still
Normal work can be kept within of short duration period, but if effectively repairing not in time, the damaged part of cable accessory can be very
Further expand soon, the electric stress control ability of cable accessory is remarkably decreased, cable cover(ing) easily makes moist into water and accelerated wind
Change, dielectric level drastically declines, service life significantly shortens, and causes the reliability of power grid bulk supply to reduce, may finally be with
Therefore machine triggers the event that similar USA New York in 2003 has a power failure on a large scale and Italy has a power failure on a large scale, in addition trigger both at home and abroad politics,
Military, economic and disastrous safety problem.
Since easy damaged part is in the branch and protecting pipe of cable accessory, the space at this it is limited and be difficult to carry out compared with
For complicated maintenance operation, the method being simply wrapped around at present using insulating tape, although this method can be to tie up in the short time
Normal power supply is held, but is examined from the service life cycle of design, the possibility to break down at random is still very high.Therefore,
The existing maintenance method for ensuring reliability can only replace cable accessory overall pulling down, cause the larger waste of resource, and repair
Cycle is grown, totally of high cost not look forward to.
Therefore, it is necessary to invent the lower cable accessory branch fingerstall of a kind of more convenient, reliability higher, cost, sheath
The restorative procedure of pipe, and be online restorative procedure.
The content of the invention
Replaced it is an object of the invention to provide one kind without overall pulling down, operate more convenient, reliability higher, cost more
Cable accessory low, long-term reliability is high and the online restorative procedure of protecting pipe.
In order to achieve the above object, a kind of cable accessory branch fingerstall restorative procedure of the present invention, including " three steps of a, b, c "
Suddenly：
A. according to the appearance and size of cable accessory branch fingerstall and protecting pipe, the injection mould of prefabricated respective shapes and size
Tool, buckle-type insulation tube；
B. damaged protecting pipe is put on into buckle-type insulation tube, applying plug with liquid to toothpaste state room temperture rubber vulcanization is buckleing
In the card slot and joint close of box-like insulation tube, buckle-type insulation tube is cured with room temperture rubber vulcanization and be integrated；
C. the damaged prefabricated injection mold of cable accessory branch fingerstall is wrapped up, injection liquid to toothpaste state room temperature sulphur
Change rubber, injection mold is removed after Cure of Rubber is vulcanized.
Further, the structure of the injection mold has mold shell, envelope weir and gum-injecting port, and mold shell is by an antithesis
Close half module or multiple moulds are put together, the structure for sealing weir is formed and is fixed on outside mould for elastic sealing ring or rigid sealing ring
The port position of shell makes liquid to toothpaste state room temperture rubber vulcanization be not easy to overflow mold shell, and gum-injecting port is tubular structure and mould
Shell inner cavity connects, and mold shell and envelope weir are using metal, wooden, plastics or any one material or two kinds of materials for vulcanizing rubber
Material is put together.
Further, the Structure of cross section of the buckle-type insulation tube in " Ω, C, G " type open type elastic tube it is any one
Kind, using Shooting Technique shaping one side of buckle-type insulation tube is carried button, another side carry buttonhole realize closure, using squeeze
Going out technological forming makes the both sides of buckle-type insulation tube carry antithesis elastic buckles and realize closure, is adopted in the appearance of buckle-type insulation tube
Wrapping, which is wound, with rope realizes that the elastic screen cloth of closure or wrap slide fastener realizes closure.
Further, the liquid is attached preferably with buckle-type insulation tube, cable to the component of toothpaste state room temperture rubber vulcanization
Any one of the consistent mono component wet solidifying type of part branch fingerstall base ingredients, two-component self-curing type resin are made, or adopt
Be made of mono component wet solidifying type, two-component self-curing type organic siliconresin any one, or using mono component wet solidifying type,
Any one of two-component self-curing type polyurethane resin is made.
A kind of cable accessory branch fingerstall restorative procedure of the present invention, its advantageous effects are：
A. overall pulling down need not be powered off and replace cable accessory branch's fingerstall and protecting pipe, it is possible to achieve online to repair, maintenance
Cost and Socialized Reading cost are low；
B. will maintenance with service mode lifting to batch production, standardization and modularization, make that repairing execute-in-place is simple, saves
Shi Shengli, maintenance speed are fast, it is ensured that and the insulation rank kimonos of the former cable accessory branch fingerstall and protecting pipe labour service life does not reduce,
It can meet six western trellis codes in the reliability of the service life cycle interior insulation of design（6σ）Quality requirement.
