Description
Technical field
The utility model relates to power technology field, relates in particular to a kind of ring main unit all insulation sheath removal tool.
Background technology
In power technology field, need to overhaul cable terminal, in maintenance process, conventionally insulator or stress cone need to be taken apart from cable end sheath.In prior art, the method for dismounting generally adopting is to use rough power that cable end sheath is extracted, if a people cannot extract sheath, many people use rope to pack into sheath, with joint efforts sheath is extracted, as many people still cannot extract, the general mode that cuts open sheath that adopts of workmen, sheath after destroying like this cannot reuse, and causes direct economic loss.According to silica gel characteristic, sheath itself be have inotropic, quite power is extracted sheath and use rope, capital is elongated sheath, after making it to reinstall, overlap off-dimension, and on sheath, can produce the fine cracks of naked eyes None-identified, in the time of power supply, produce partial discharge, become potential safety hazard, affect power supply reliability.
In addition, remove for convenience cable end sheath, will make sheath inside reserve space, the general direct use straight screwdriver of construction team inserts in the middle of cable end sheath and insulator or stress cone.Use straight screwdriver very easily to scratch and even damage sheath, insulator or stress cone.
(1) if sheath damages, need to change a whole set of cable end sheath, can cause direct economic loss.
(2) if insulator damages to be needed to change, need whole power failure according to ring main unit structural principle overwhelming majority ring main unit, after having changed, need again to annotate sulfur hexafluoride gas; If do not change, can cause gap discharge, partial short-circuit.
(3) if the insulating barrier of cable end damage, in cable running, can therefore produce creepage, produce partial discharge.Thereby this potential safety hazard do not eliminate can cause cable long-play and seriously heating make cable accelerate aging even blast.
Therefore, existing cable end protective cover method for dismounting drawback is a lot of, and equipment is had to very high damage ratio.Being not only construction member is difficult to cable terminal to remove also manpower, financial resources have all been increased to burden.Cable terminal part sustains damage to change and not only causes economic loss, and the workload that has increased construction teams and groups has also been dragged slowly job schedule.If sustaining damage, cable terminal part do not have timely reparation to form potential safety hazard yet, these potential safety hazards are not got rid of, gently impact supplies power transmission among a small circle, heavy the accident of may blasting, cause casualties and property loss, and can cause large area blackout, its economic loss is difficult to calculate, and electric power system is produced to long-range harmful effect.
