Abstract
The utility model relates to a protection rope, in particular to a live-working short-circuit protection rope working above a voltage grade of 35kV. The main points of the structure lie in that the protection rope comprises a grounding device, a grounding line, an insulated line and a high magnetic device, wherein one end of the grounding line is connected with the grounding device, and the other end of the grounding line is connected with the high magnetic device; one end part of the insulated line is connected to the grounding device or a pole-and-tower cross arm, and the other end part of the insulated line is connected with the high magnetic device. The protection rope has the advantages that the high magnetic device is in adsorption contact with a porcelain bottle socket of an insulator string, so that when the insulator string is detached from the cross arm, the high magnetic device can be detached from the porcelain bottle socket smoothly and completely instead of being stopped, thereby ensuring the safety wrestle between operators and high voltage electricity or induced electricity and guaranteeing the personnel safety of the live-working operators; and meanwhile, the protection rope has the advantages of simple structure, convenient carrying, convenient operation, and reduction of direct contact between operators and electrified body.
Description
Technical field
The utility model relates to a kind of protection rope, particularly a kind of 35kV and above electric pressure live line working short circuit protection rope.
Background technology
The charged for replacement insulator is as a conventional repair method in the transmission line hotline maintenance, in daily live line working, occupied extremely important position, but this operating type at highfield also is the operational method of a high-risk simultaneously, because the porcelain vase iron bowl head of 35kV and above electric pressure cross-arm side can produce very strong induced voltage after breaking away from shaft tower, this induced voltage reaches hundreds of usually even goes up kilovolt, to such an extent as to can " " discharge to iron tower.In the prior art when changing insulator, adopt a kind of clip to clamp porcelain vase bowl head, use action bars to the insulator string operation of threading off then, because action bars is shorter, when operating, the porcelain vase bowl head that the total inevitably contact of human body is being discharged causes induction of electric shock, thereby is threatening staff's job safety.
When insulator string and cross-arm dropout, because the clamping force of clip may be excessive, perhaps clip since other reasons such as fault by locked, still clamp porcelain vase bowl head, cause the insulator string band clip and action bars comes off, this will cause safe distance deficiency between human body at this moment and the high-tension line (porcelain vase bowl head), and human body is subjected to the threat of high-tension electricity by the clip discharge at any time, so there is great potential safety hazard in the power tool of the prior art.In addition because the complex structure of clip and action bars thereof carries also very inconvenient.
Invention constitutes
The purpose of this utility model is to provide a kind of job safety according to the deficiencies in the prior art part, and is simple in structure, portable 35kV and above electric pressure live line working short circuit protection rope.
The utility model is realized by following approach:
35kV and above electric pressure live line working short circuit protection rope; its structural feature is; include earthing device, earth connection, insulation rope and high magnetic device; one end of earth connection is connected with earthing device; the other end is connected with high magnetic device; one end of insulation rope is connected on earthing device or the shaft tower cross-arm, and the other end is connected on the high magnetic device.
During use, one end of insulation rope can be connected according to the practical operation needs safe length at scene on earthing device or the shaft tower cross-arm, earthing device is fixed on the cross-arm, high magnetic device then is adsorbed on the porcelain vase bowl head, high magnetic device should adopt the high material of magnetic force, assurance is to the absorption affinity of porcelain vase bowl head, during operation, the induced current of porcelain vase bowl head is by the earth connection earial drainage, when insulator string broke away from cross-arm, it came off downwards, because high magnetic device and the absorption of porcelain vase bowl head touch, the connection that does not exist other to lock, therefore under the action of gravity of insulator string, high magnetic device meeting breaks away from porcelain vase bowl head smoothly, finishes the disengaging fully of short circuit protection rope and insulator string, guaranteed that the staff has kept the safe distance with high-tension electricity when operation, be protected its personal safety; Simultaneously, the original relatively technology of operation short circuit protection rope structure described in the utility model is simple, and its insulation rope adopts the software rope, does not take the place on the space, and is therefore easy to carry.
The utility model can further be specially:
Earthing device is a kind of earth clip device, installs porose on it.
During use, the earth clip device is clipped on the cross-arm earthing position, adopts fasteners such as screw or bolt that the earth clip device is fixedly mounted on the cross-arm earthing position.
Earth connection is a kind of annealed copper wire of exterior insulation.
Can further be specially: earth connection is that a kind of cross section is 16 square millimeters a multiply insulation annealed copper wire.The earth connection of the high electric current of high pressure requires the conductance height, and the connecting line that cross section is suitable is convenient to the induced current earial drainage on the insulator string porcelain vase bowl head.The extexine of annealed copper wire need apply or increase a layer insulating.
The insulation rope is a kind of soft insulation rope.
Can further be specially: the insulation rope is a kind of soft insulation rope with length adjustment device.Like this, on the space side of occupation of land not, can also operate according to field requirement adjustment insulation rope length, not only convenient but also simple, can the minimizing personnel contact with the direct of electrified body in the scope of control, has further ensured personnel's safety.
High magnetic device is a kind of high magnetic device for carrying a tripot magnet.
High magnetic device can adopt the magnet or the magnetic devices of high magnetic, and the high magnetic device of test is excellent with high magnetic device for carrying a tripot magnet effect at present, does not get rid of to be more preferably appropriate products.
In sum; advantage of the present utility model is; a kind of 35kV and above electric pressure live line working short circuit protection rope is provided; it uses high magnetic device and insulator string porcelain vase bowl head to carry out absorption type and touches; like this; at insulator string when cross-arm breaks away from; because this absorption type touches, make the disengaging porcelain vase bowl head that high magnetic device can be smooth and complete, and can not lived by band; personnel and high-tension electricity have been ensured; safety between the induced electricity is wrestled; guaranteed the operating personnel's of charged work personal safety, simultaneously simple in structure, be easy to carry; it is also very convenient to operate, and has reduced personnel and has contacted with the direct of electrified body.
