Abstract
The utility model relates to a synthetic insulating cross arm used for a high-tension transmission circuit and a substation to bring a support and an insulated conductor into one integration, also called column-type synthetic insulator, comprising an inner core which is a spun glass enhanced type epoxy resin conic rod, a silicon rubber sleeve molded by the integrated mold pressing and sheathed outside the inner core, an aluminium alloy connecting supporting seat arranged on the bottom end of the conic rod, and the top of the conic rod is composed of an aluminium alloy clip. The utility model has the advantages of high mechanical strength, and excellent performances of electrical insulation, moisture protection, weather resistance and ageing resistance. The utility model is used for power transmission circuits, capable of enhancing the level of pollution flashover prevention, reducing the distance of phase insulation, lowering the height of tower, saving steel for circuit and tower and land for corridor, thus to lower the cost of circuit.
Description
The utility model relates to ultra-high-tension power transmission line and transformer station and is used to support a kind of novel composite insulation cross-arm with insulated conductor.
At present, the suspension type synthetic insulator that is mainly column support type and suspended porcelain insulator and develops in recent years as ultra-high-tension power transmission line and transformer station's main insulation, but operation finds that they all exist some problems and deficiency, have influence on the safe operation of power circuit, also cause the power circuit construction cost to improve.For example suspended porcelain insulator and synthetic insulator are considered windage yaw because of need, so phase spacing is big, the circuit corridor is wide, need long iron cross arm that hitch point is set, and the lightning conducter installation site is also higher relatively.Column support type porcelain insulator anti-fouling flashover performance is relatively poor, and need in service carry out antifouling processing, and maintenance workload is big.In recent years a kind of porcelain pole arm that is used for 35 kilovolt puts into operation, but because of bending strength is low, the cascade fracture accident takes place easily, and anti-fouling flashover performance is poor, is not suitable in the ultra-high-tension power transmission line more than 110 kilovolts.
The purpose of this utility model provides a kind of ultra-high-tension power transmission line that is used for, and has the mechanical strength height, and strong, the moistureproof and anti-weathering aging function admirable of electric insulating quality integrates the composite insulation cross-arm of the insulating effect of the supporting role of iron cross arm and insulator.Also can be used for transformer station, then be called the column support type synthetic insulator.
The utility model is realized as follows, by glass-fiber reinforced epoxy resin tapered rod is inner core, be set with the silicon rubber skirt cover of integral die forming outward, the awl bottom device has aluminium alloy to connect bearing, vertex of a cone end has an aluminium alloy wire clamp, all is equipped with filler between tapered rod and bearing and tapered rod and wire clamp.The bottom of glass-fiber reinforced epoxy resin tapered rod is tubular, and according to the stressed big or small length that determines pipe, also can be made into the whole conical pipe that is.
The utility model has the advantages that inner core adopts glass-fiber reinforced epoxy resin tapered rod, compactness is strong, mechanical strength height, electrical insulation properties and anti-weathering aging function admirable.Tapered rod adopts the pipe integrated or conical pipe structure of rod according to stressed size, and material is saved in the deadweight that can alleviate the composite insulation cross-arm, does not influence its mechanical strength again.Silicon rubber skirt cover has guaranteed the electric property long-term stability for integral die forming.Adopt aluminium alloy to connect bearing and wire clamp, in light weight being convenient to installed.The utility model integrates the supporting role of iron cross arm and the insulating effect of insulator, ultra-high-tension power transmission line adopts the utility model, can improve anti-soil sudden strain of a muscle level, can dwindle the phase insulation distance again, reduce the shaft tower height, a large amount of overhead line structures steel and corridor lands used saved are a kind of novel used for transmission line insulator arrangements.If aluminium alloy is connected bearing changes ring flange into, promptly be transformer station's column support type synthetic insulator.
Accompanying drawing is a structure chart of the present utility model.
Wherein, 1-aluminium alloy wire clamp, 2-filler, 3-silicon rubber skirt cover, 4-glass-fiber reinforced epoxy resin tapered rod, 5-aluminium alloy connects bearing.
An embodiment of the present utility model is as follows, with glass fibre and epoxy resin ratio in 3: 2, adopt vacuum compression molding method to make glass-fiber reinforced epoxy resin tapered rod, silicon rubber skirt cover adopts integral die forming, be sleeved on outside the glass-fiber reinforced epoxy resin tapered rod, and bonding with the special bonding agent.The awl bottom is loaded onto aluminium alloy and is connected bearing, and vertex of a cone end is loaded onto the aluminium alloy wire clamp, and the filler that is made into epoxy resin and adhesive is filled sealing and promptly made the composite insulation cross-arm respectively.When this cross-arm was installed on iron tower of power transmission line, as long as aluminium alloy is connected bearing to link to each other with iron tower, the aluminium alloy wire clamp hung lead and promptly finishes.
