The utility model object is achieved in that a kind of high voltage iron tower lightning conducter or composite ground wire replacing separation net, its key is: comprise two insulation head-ropes that hanging device is parallel with two, left section of described insulation head-rope and right section are hung on two described hanging devices, between two described insulation head-ropes, be evenly provided with the row connection cord that insulate, the two ends of this insulation connection cord are fixedly connected with two eradication edge head-ropes respectively, described insulation connection cord is between described hanging device, between two described insulation head-ropes, be provided with row's strut, these strut two ends are separately fixed on two described insulation head-ropes, described strut between described hanging device, the two ends of described insulation head-rope are provided with fixture and tightening device, and this tightening device is between described hanging device and fixture.
Adopt said structure, insulation connection cord and insulation head-rope form network structure, and strut struts head-rope, ensure that head-rope can closing waist, assemble after this separation net, separation net is by lightning conducter (or composite ground wire) and power line isolation, construction part is separated with charged part, keep a safe distance, while changing lightning conducter, lightning conducter can not ride on power line, therefore changes lightning conducter (or composite ground wire) without power-off, easily and effectively, greatly reduce energy loss and user's economic loss.
Above-mentioned hanging device comprises fixed lever, and the two ends of this fixed lever are all fixed with fixed pulley, and described fixed lever is fixed on high voltage iron tower, and two described insulation head-ropes are hung on two described fixed pulleys.
Adopt said structure, fixed lever is convenient to the fixing of fixed pulley, fixed pulley the pulling of head-rope of being convenient to insulate, and the width that simultaneously increases separation net meets or exceeds the maximum spacing of power line on same level face, carrys out the normal operation of insulation blocking power circuit with this.
Above-mentioned tightening device is lever hoist, and this lever hoist is near described fixture.
Adopt said structure, lever hoist is easy for installation, and is convenient to take-up tension.
Above-mentioned fixture is earth anchor, and the end of described insulation head-rope is fixed on described earth anchor.
Adopt said structure, insulation head-rope is fixed by earth anchor and ground, more firm.
Above-mentioned strut is made up of epoxy resin, and described fixed lever is made up of aluminium alloy, and described insulation head-rope and insulation connection cord are Di Nima rope.
Adopt said structure, the fixed lever that aluminium alloy is made is light, is convenient to be transported high voltage iron tower, and intensity is high, durable; And the strut quality that epoxy resin is made is light, hardness also can meet supporting role, has alleviated the load-bearing of insulation head-rope; Stress intensity, dielectric strength and the rub proofness of enlightening Nima rope are high, and its tensile strength is high, are that 15 times of high-quality steel, elongation are little, lightweight, be same diameter steel 1/7th, can bubble through the water column, flexible.
Beneficial effect: a kind of high voltage iron tower lightning conducter of the utility model or composite ground wire replacing separation net, by separation net, lightning conducter and power line are isolated, remain safe distance, can prevent that lightning conducter from riding on power line in Renewal process, cause safety problem, change lightning conducter without power-off, reduced energy loss and user's economic loss.
