The composite interphase spacer comprises metal ends, a core rod, a sheath and sheds, and is characterized in that the core rod (2) is a solid glass fiber-reinforced epoxy resin drawn rod, and is wrapped by the vulcanizing drying tunnel sheath (3) and the high-temperature vulcanized silicon rubber half sheds, and the metal ends (1) are fixedly mounted on both ends of the core rod (2). The composite interphase spacer solves the shaking problem of high-voltage overhead line wires, the cost is reduced, the weight of the composite interphase spacer is reduced, the burden of lines is decreased, and the composite interphase spacer is convenient to mount, and has the advantages of simple structure, bending resistance and good corrosion resistant and insulating properties.
Description
Technical field
Exchange overhead transmission line and use compound inter-phase spacer, be specifically related to a kind of outdoor insulative 35kV, 110kV, 220kV interchange overhead transmission line that the power industry high voltage power transmission uses and use compound inter-phase spacer.
Background technology
Along with the fast development of China's power industry, high voltage overhead power transmission sequence conductor galloping is one of main threat of line security operation, has become the main harm factor of the normal operation of circuit.The lead inter-phase spacer is to be used to one of effective measures that prevent overhead transmission line galloping, the effect of conductor spacer: (1) prevents the whiplash between the sub-conductor; (2) suppress aeolian vibration; (3) suppress subspan oscillation.Though conductor spacer is a kind of attached gold utensil, be related to the security of operation and the useful life of bundle conductor, prevent conductor galloping extensive application all at home and abroad.Exchange overhead transmission line and also stablizing rising with the market demand of compound inter-phase spacer.The interchange overhead transmission line of present outdoor use is generally full umbrella skirt construction with compound inter-phase spacer, and not only the cost of raw material is high, and himself weight escheat has caused certain burden to circuit.
Summary of the invention
The technical problem that the utility model will solve is: overcome the problem that prior art exists, provide a kind of in light weight, mechanical strength is high, the overhead transmission line that exchanges of anti-waving property and good insulation preformance is used compound inter-phase spacer.
The utility model solves the technical scheme that its technical problem adopted: this interchange overhead transmission line is used compound inter-phase spacer; Comprise metal termination, plug, sheath and full skirt; It is characterized in that: described plug is solid glass fiber reinforced epoxy resin leading-drawing rod; Outside at plug coats sulfuration drying tunnel sheath and high-temperature silicon disulfide rubber half full skirt, is fixed with the metal termination at the two ends of plug.
Described metal is provided with fixing hole on the termination.
The fixing hole that is provided with on the described metal termination is single hole or diplopore.
Described metal end head material is a cast steel hot galvanizing material.
Described half full skirt is vulcanizing drying tunnel sheath two ends left-right symmetric by big full skirt and little full skirt, and per two umbellule skirts are provided with a big full skirt at interval, and big full skirt and little full skirt are downward-sloping.
Compared with prior art; The interchange overhead transmission line of the utility model with the beneficial effect that compound inter-phase spacer had is: adopted half full skirt composite insulating material structure; Not only practice thrift the cost of raw material, also alleviated own wt and circuit burden greatly, improved the bending-twisting ability of conductor spacer; Improve its rigidity greatly, reduced side-play amount.Insulated part adopts to be made up of high strength glass fiber leading-drawing rod and silicone rubber jacket and half full skirt, and it has in light weight, simple in structure, mechanical strength advantages of higher, and silicon rubber compound inslation surface has hydrophobicity and migration of hydrophobicity; Can improve the stain resistance of product greatly; Corrosion resistance is good, and good insulation preformance, non-maintaining does not need periodic inspection; Be coated with silicone oil, practice thrift a large amount of regular maintenance expenses.
Description of drawings
Fig. 1 is that the utility model exchanges the structural representation of overhead transmission line with compound inter-phase spacer, is the most preferred embodiment of the utility model.
Wherein: 1 metal termination, 2 plugs, 3 sheaths, 4 big full skirt 5 umbellule skirts 6 fixing holes.
Embodiment
Interchange overhead transmission line below in conjunction with 1 pair of the utility model of accompanying drawing is done further elaboration with compound inter-phase spacer.
Shown in accompanying drawing 1; This interchange overhead transmission line is made up of metal termination 1, plug 2, sheath 3, big full skirt 4, umbellule skirt 5 and fixing hole 6 with compound inter-phase spacer; Middle part at plug 2 coats with sulfuration drying tunnel sheath 3, connects with metal termination 1 with compression joint technique at the two ends of plug 2 then.Described plug 2 is a solid glass fiber reinforced epoxy resin leading-drawing rod; Plug 2 outside composite jackets 3, big full skirt 4 and umbellule skirt 5 are half full skirt; Big full skirt 4 is vulcanizing drying tunnel sheath 3 two ends left-right symmetric with umbellule skirt 5; Per two umbellule skirts 5 are provided with a big full skirt 4 at interval, and big full skirt 4 is downward-sloping with umbellule skirt 5.Sheath 3, big full skirt 4 and umbellule skirt 5 all adopt high-temperature silicon disulfide rubber to process.Two fixing holes 6 are set on the described metal termination 1.Described metal termination 1 material is a cast steel hot galvanizing material.
1 fixing hole 6 also can be set on the described metal termination 1.
During assembling, metal termination 1 connects with the end of plug 2 adopts the encapsulate compression joint technique, and the big full skirt 4 at two ends adopts whole the notes to press one-shot forming technique with umbellule skirt 5, and the technology of middle part sheath 3 usefulness sulfuration drying tunnel is coated on the plug 2.Overall structure is simple, and own wt is light, has not only practiced thrift the cost of raw material, has also alleviated own wt and circuit burden greatly, has stronger bending resistance and torsional property.
It is that the interchange overhead transmission line of 35kV, 110kV, 220kV is used compound inter-phase spacer that the utility model is mainly used in specification.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection range of the utility model technical scheme according to the technical spirit of the utility model.
