Description
Technical field
The present invention is to provide the power transmission lines fixture of electric field, specifically a kind of live-wire work insulating cross arm.
Background technology
Current domestic existing 10kV live-wire work insulating cross arm cannot effectively use, and there is unsafe drawback, not only increases the hazards of operating personnel and does not have again the requirement improving power supply reliability.And need the replacing insulator crossarm that has a power failure, reduce operating efficiency.
Summary of the invention
In order to overcome the shortcoming of existing insulator crossarm, the invention provides a kind of live-wire work insulating cross arm.This cross-arm by installing leg-of-mutton support on electric pole, each support is installed lifting rope pulley and suspension hook carries out lifting wire, the technical problem of the charged installation of solution wire.
The scheme that technical solution problem of the present invention adopts is:
Electric pole is installed with anchor ear by jackscrew, anchor ear is separated by 120 ° by support and anchor ear connecting frame is outward-dipping is provided with support, stent bolt fag end is provided with at pedestal upper end, diameter adjustment hoop is connected with on anchor ear top, diameter adjustment hoop top is connected with center pole, is provided with carriage center head in center pole upper end, is connected with stay cord between carriage center head and stent bolt fag end, each stent bolt fag end is connected with lifting hook pulley by rope, has suspension hook at the bottom bolt of lifting hook pulley.The square tube that support adopts epoxy resin composite material to make.
Good effect, the vertical load of original cross-arm carrying wire, when charged for replacement wire, is transferred on insulator crossarm, is ensured that wire is solid and reliable by the present invention.And utilize the lifting on insulator crossarm device by the lifting in various degree of the height of three-phase conducting wire or reduction.Can 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.Be suitable on power transmission device for applying in charged conducting wire.
Accompanying drawing explanation
Fig. 1 is insulator crossarm configuration state figure of the present invention
In figure, 0. electric pole, 1. anchor ear, 2. support, 2.1. support and anchor ear connecting frame, 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
Electric pole is installed with anchor ear 1 by jackscrew, anchor ear is separated by 120 ° by support and anchor ear connecting frame 2.1 is outward-dipping is provided with support 2, stent bolt fag end 2.2 is provided with at pedestal upper end, diameter adjustment hoop 3 is connected with on anchor ear top, diameter adjustment hoop top is connected with center pole 7, carriage center 4 is provided with in center pole upper end, stay cord 5 is connected with between carriage center head and stent bolt fag end, each stent bolt fag end is connected with lifting hook pulley 6 by rope, has suspension hook 6.1 at the bottom bolt of lifting hook pulley.
The square tube that support adopts epoxy resin composite material to make, ensures insulation property.
Use procedure of the present invention:
The wire of pre-installation is fastened on suspension hook, pulls rope, suspension hook is sling to setting height, carries out charged conducting wire.According to the length of cross-arm, by pulling up and the center pole that falls, the angle of support and electric pole is made to increase or reduce, thus the distance of change two between support, realize the requirement adapting to cross-arm length.
Cross-arm is used for pull-up wire.By the length of degree of tightness stay cord and the rope lengths on lifting hook pulley top, flying leads can be made to reach setting height.
Utilize existing insulator crossarm to be combined into triangle wire is sling, by the characteristic of mechanics, the vertical load of wire is decomposed, then make the upper and lower convergent-divergent of wire by stringing.The vertical range of wire can be made to reach suitable operation height.
The fulcrum bottom of middle term wire is fixed on holds tightly on the anchor ear of electric pole, locks anchor ear, prevent insulator crossarm from waving with jackscrew.
Feature of the present invention:
1, industrial frequency withstand voltage 45KV, without punch-through in 1 minute.
2, mechanical strength and hot strength reach specification technique index.
3, insulation property reach specification technique index.
4, can restringing under electriferous state.
The present invention can charged for replacement wire time, transfer on insulator crossarm by the vertical load of original cross-arm carrying wire, guarantee wire is solid and reliable.And the lifting on insulator crossarm device can be utilized the lifting in various degree of the height of three-phase conducting wire or reduction.Can 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 that all straight line poles change cross-arm.
