Abstract
The utility model discloses an insulation crossarm, which comprises cross rods (1), an arc-shaped connecting part (2), chain locks (3) and clamping grooves (4); the cross rods adopt circular hollow structures, and are made of composite insulation material; the arc-shaped connecting part is arranged in the middle of the cross rod; the chain locks are fixedly connected to the cross rods on two sides of the arc-shaped connecting part respectively and are fixedly connected with a wire pole; and the clamping grooves used for fixing conducting wires are arranged at two lateral ends of the cross rods respectively. The utility model solves the problem that the insulation tool in a single crossarm for hot-line replacement of 10 KV overhead line in the hot-line work is not matched with the iron crossarm of the wire pole; moreover, due to the adoption of the hollow structures and the composite insulation material, the utility model has the advantages of light weight, convenient installation, high withstand voltage property, great strength, wide retractable range (the approximate lengths of the chain locks using the wire pole), and economy and practicality, and improves the safety coefficient of hot-line work and working efficiency of hot-line work.
Description
Technical field
The utility model belongs to distribution line live working originates with the cross-arm technology, and what relate generally to is a kind of insulator crossarm, is applicable in the live line working of 10KV overhead transmission line to use.
Background technology
Along with improving constantly of social modernization's level, also more and more higher to the requirement of power supply reliability.How just can accomplish not have a power failure, lack power failure, satisfy the demand of economic society to the electric power uninterrupted power supply? carrying out distribution line live working energetically is the effective measures that power supply reliability, realization uninterrupted power supply improve in power supply enterprise, be the urban distribution network minimizing scheduled outage time, shorten pressing for of fault outage time, also realizing bringing into play very positive effect aspect power grid security reliability service, minimizing energy loss, the raising electrical network economy benefit simultaneously.
Cross-arm is one of critical piece of distribution line overhead transmission line.At present, the cross-arm that adopts at 10KV overhead transmission line single back line mostly is iron cross arm, because wind and weather all the year round, phenomenons such as burn into is aging, distortion can appear in iron cross arm, as untimely replacing, can increase the fault outage number of times, cause potential safety hazard to operation of power networks.When the charged for replacement cross-arm, generally adopted the insulation strut of bucket arm vehicle special use to change in the past.The wide 150mm of this insulation strut, thick 70mm, long 2200mm; the volume heaviness; two ends lead draw-in groove all is a hardware; not only can increase live line working personnel's danger coefficient; and when mounted, insulation strut and the unmatched phenomenon of iron cross arm length (the insulation strut two ends can exceed about iron cross arm and lead 250mm usually) often appear, charged lifting or falling lead bother very much; bring inconvenience to operation, influenced operating efficiency.
Summary of the invention
The purpose of this utility model produces thus, proposes a kind of insulator crossarm.Solve instrument and the unmatched problem of electric pole iron cross arm when changing cross-arm in the live line working, the coefficient of safety when having increased live line working has improved the operating efficiency of charged for replacement cross-arm, has prolonged the useful life of cross-arm.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it is made of cross bar, arc connector, chain lock and draw-in groove, cross bar is circular hollow structure, the employing composite insulating material is made, middle part at described cross bar is provided with arc connector, on the cross bar of these arc connector both sides, be fixedly connected with chain lock respectively and be used for fixedlying connected, be respectively arranged with draw-in groove at the both sides of described cross bar end and be used for fixing lead with electric pole.
The utility model has solved in the live line working insulating tool and the unmatched problem of electric pole iron cross arm in the charged for replacement 10KV overhead transmission line list cross-arm, because it is a hollow structure, and adopt composite insulating material to make, not only in light weight, easy for installation, withstand voltage properties is high, intensity is big, big (chain lock use electric pole length exists flexible scope
About), economical and practical, and improved the coefficient of safety of live line working and the operating efficiency of live line working.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, cross bar, 2, arc connector, 3, chain lock, 4, draw-in groove.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure: insulator crossarm described in the utility model is made of cross bar 1, arc connector 2, chain lock 3 and draw-in groove 4, cross bar 1 is circular hollow structure, the employing composite insulating material is made, thick 5mm, diameter 50mm, long 1700mm, withstand voltage 45KV, load-bearing reaches 70kg, all meets " electric power safety rules " regulation.Arc connector 2 adopts insulating material to make, and is socketed in the middle part of cross bar 1, and the semi arch of its arc degree and electric pole matches.Being fixedly connected with chain lock 3 on the body of arc connector 2 respectively is used for fixedlying connected with electric pole.Be respectively arranged with draw-in groove 4 at the both sides of cross bar 1 end and be used for fixing lead, draw-in groove 4 also adopts composite insulating material to make, be provided with jam plate in the top, during use lead is put into the fixing back of draw-in groove 4 usefulness jam plates and just can prevent that lead from from draw-in groove 4 landings, further improving the coefficient of safety of operation and the reliability of power supply.
During use, adopt bucket arm vehicle above needs replacing iron cross arm, position, the 400mm-600mm left and right sides to be installed by this insulator crossarm, the arc part of arc connector 2 is close on the cambered surface of electric pole, tighten up fixing with chain lock, with bucket arm vehicle with lead put into the insulation draw-in groove after, can carry out replacing to cross-arm.
Claims (2)
1. insulator crossarm, comprise cross bar (1), it is characterized in that: described cross bar (1) is circular hollow structure, the employing composite insulating material is made, be provided with arc connector (2) in the middle part of described cross bar (1), on the cross bar (1) of described arc connector (2) both sides, be fixedly connected with chain lock (3) respectively and be used for fixedlying connected, be respectively arranged with draw-in groove (4) at the both sides end of described cross bar (1) and be used for fixing lead with electric pole.
