Abstract
The invention provides a live-wire work insulating cross arm. A hoop is retained on a pole through a jackscrew; supports are mounted outwards and slantwise on the hoop at intervals of 120 degrees through a support-hoop connector; a support rope tying head is arranged at the upper end of the support; a diameter adjusting hoop is connected to the upper portion of the hoop; a center rod is connected to the upper portion of the diameter adjusting hoop; a support center head is arranged at the upper end of the center rod; a pull rope is connected between the support center head and the support rope tying head; a hook pulley is connected to each support rope tying head through a rope; and a hook is tied to the lower portion of the hook pulley. The live-wire work insulating cross arm is capable of replacing a lead through live-wire work, and also capable of effectively controlling the air gaps and safe distances between the lead and the cross arm and other wires arranged in parallel on the same pole; in short, the live-wire work insulating cross arm is convenient to mount, simple to operate, and universal to multiple layers of leads. Besides, the live-wire work insulating cross arm is applicable to mounting leads through live-live work on a power transmission device.
Description
Technical field
The present invention is to provide the power transmission lines fixture of electric field, specifically a kind of live line working insulator crossarm.
Background technology
Domestic existing 10kV live line working insulator crossarm can't effectively use at present, exists unsafe drawback, has not only increased operating personnel's hazards but also has not had the requirement that improves power supply reliability again.And need to have a power failure and change insulator crossarm, reduced operating efficiency.
Summary of the invention
In order to overcome the shortcoming of existing insulator crossarm, the invention provides a kind of live line working insulator crossarm.This cross-arm is through installing leg-of-mutton support on electric pole, installation lifting rope pulley and suspension hook lift lead on each support, solve the technical problem of the charged installation of lead.
The scheme that technical solution problem of the present invention is adopted is:
On electric pole, be installed with anchor ear, be separated by 120 ° on the anchor ear, be provided with the stent bolt fag end in the support upper end through support and the outward-dipping support that is equipped with of anchor ear link through jackscrew; Be connected with the diameter adjustment hoop on anchor ear top; Diameter adjustment hoop top is connected with center pole, is provided with the carriage center head in the center pole upper end, is connected with stay cord between carriage center head and the stent bolt fag end; On each stent bolt fag end, be connected with lifting hook pulley through rope, bolt has suspension hook in the bottom of lifting hook pulley.The square tube that support adopts epoxy resin composite material to process.
Good effect, the present invention is when the charged for replacement lead, and the vertical load that original cross-arm is carried lead is transferred on the insulator crossarm, guarantees the lead secure.And utilize up-down on the insulator crossarm device with the height lifting or the reduction in various degree of three-phase conducting wire.The effectively air gap of other circuit of pilot and cross-arm and parallel lines on same tower and safe distance have the advantages that easy for installation, simple to operate, multi-layer conductor leads can both be general.Suiting on power transmission device, to be used for charged installation lead uses.
Description of drawings
Fig. 1 is insulator crossarm configuration state figure of the present invention
Among the figure, 0. electric pole, 1. anchor ear, 2. support, 2.1. support and anchor ear link, 2.2. stent bolt fag end, 3. diameter adjustment hoop, 4. carriage center head, 5. stay cord, 6. suspension pulley, 6.1. suspension hook, 7. center pole.
Embodiment
On electric pole, be installed with anchor ear 1 through jackscrew; Be separated by 120 ° on the anchor ear through support and the anchor ear link 2.1 outward-dipping supports 2 that are equipped with; Be provided with stent bolt fag end 2.2 in the support upper end, be connected with diameter adjustment hoop 3 on anchor ear top, diameter adjustment hoop top is connected with center pole 7; Be provided with carriage center 4 in center pole upper end; Be connected with stay cord 5 between carriage center head and the stent bolt fag end, on each stent bolt fag end, be connected with lifting hook pulley 6 through rope, bolt has suspension hook 6.1 in the bottom of lifting hook pulley.
The square tube that support adopts epoxy resin composite material to process guarantees insulation property.
Use of the present invention:
The lead of installing is in advance fastened on suspension hook, and the pulling rope makes the suspension hook setting height of slinging, and carries out charged installation lead.According to the length of cross-arm, through pulling up and the center pole that falls, the angle of support and electric pole is increased or dwindle, thereby change two at a distance of the distance between the support, realize adapting to the requirement of cross-arm length.
Cross-arm is used for the pull-up lead.Through the length of degree of tightness stay cord and the rope lengths on lifting hook pulley top, can make unsettled lead reach setting height.
Utilize existing insulator crossarm that it is combined into triangle and sling lead, the characteristic through mechanics is decomposed the vertical load of lead, makes the upper and lower convergent-divergent of lead through stringing again.Can make the vertical range of lead reach suitable operation height.
Be fixed on the fulcrum bottom of discipline lead on the anchor ear of holding electric pole tightly, lock anchor ear, prevent that insulator crossarm from waving with jackscrew.
Characteristics of the present invention:
1, industrial frequency withstand voltage 45KV did not have punch-through in 1 minute.
2, mechanical strength and hot strength reach the specification technique index.
3, insulation property reach the specification technique index.
4, restringing under can electriferous state.
When the present invention can the charged for replacement lead, the vertical load that original cross-arm is carried lead was transferred on the insulator crossarm, assurance lead secure.And the up-down on the insulator crossarm device capable of using is with the height lifting or the reduction in various degree of three-phase conducting wire.The effectively air gap of other circuit of pilot and cross-arm and parallel lines on same tower and safe distance have the advantages that easy for installation, simple to operate, multi-layer conductor leads can both be general.Overcome the difficulty of all straight line poles replacing cross-arms.
