Abstract
Light-duty compound cross-arm and the pillar filling solid insulator it is interrupted in epoxy fiberglass tubes.Product of the present invention is made up of upper adnexa 1, epoxy fiberglass tubes 2, silicon rubber umbrella skirt 3, insulation support plate 4, insulation air bag 5, filling insulant 6 and lower adnexa 7.The innovation of the present invention: a, insulation support plate 4 is installed in epoxy fiberglass tubes 2 and after filling insulant, epoxy fiberglass tubes inwall leakage current and air breakdown are blocked, do not lose circle deformation when can support again epoxy fiberglass tubes flexural loading, add the rigidity of product, decrease bending deformation quantity.B, in epoxy fiberglass tubes 2 install insulation air bag 5, alleviate product weight, save raw material, reduce cost, the space that circle deformation is transferred in capsule can will be lost again when epoxy fiberglass tubes flexural loading, simultaneously because implant is less, reduce the different impact on product of bi-material swell-shrink coefficient, it is to avoid interface and solid material tear or the air gap of recoverable force formation not in place.
Description
Technical field
The present invention relates to high pressure, supertension and extra-high voltage electric power field, be mainly used as insulator crossarm and transformer station's insulation column of iron tower of power transmission line.
Background technology
High pressure, supertension and extra-high voltage electric power transmission line of electricity generally use steel cross-arm and add suspension insulator the most both at home and abroad, and the widely used insulation column of transformer station is porcelain pillar.Steel cross-arm adds suspension insulator makes steel tower increase, and line corridor is widened.Porcelain pillar is antifouling, shockproof effect is bad, and Heavy Weight, and cost of transportation is high, installs inconvenience.In recent years, some scientific research institutions and company have developed several compound inslation pillar, all there is not all roses part, different defects is there is: 1, using epoxy glass pultrusion rod as plug primarily as the plug bearing mechanical load, but limited by manufacturing process, can not produce the diameter pultrusion rod more than 130mm, and solid pultrusion rod poor rigidity, bending deformation quantity is big；2, using porcelain knob as plug, major defect is that manufacturing cost is high, poor seismic behavior；3, being wound around epoxy glass outside pultrusion solid bar, the most successively increase diameter of mandrel, subject matter is that cost is high, and layering shaped interface exists air gap；4, insulating gas is filled in epoxy fiberglass tubes, the necessary external air gauge of this product, whether leak in order to gas in monitoring pipe, add the maintenance workload of operation department, user is difficult to accept；5, filling solids in epoxy fiberglass tubes, the density such as implant is big, then Heavy Weight, and cost is high；Density such as implant is little, then longtime running is likely to occur shelf depreciation under High Voltage electric field.And implant can not be consistent with the swell-shrink coefficient of epoxy fiberglass tubes bi-material, the inconsistent meeting of size expanded with heat and contract with cold causes bonding interface tear occur.It addition, the little implant of density is difficult to bear extruding force, circle deformation when insulation tube bears bend loading, can be lost, cause implant tear or extruding to recover not in place after losing circle and form air gap, insulation defect in being formed.
Summary of the invention
The present invention is directed to the problems referred to above, it is desirable to provide a kind of good electric property, dielectric strength is high, saves raw material, is interrupted light-duty compound cross-arm and the pillar filling solid insulator in reducing the epoxy fiberglass tubes of cost.
Product of the present invention is made up of upper adnexa 1, epoxy fiberglass tubes 2, silicon rubber umbrella skirt 3, insulation support plate 4, insulation air bag 5, filling insulant 6 and lower adnexa 7.
The innovation of the present invention: a, insulation support plate 4 is installed in epoxy fiberglass tubes 2 and after filling insulant, epoxy fiberglass tubes inwall leakage current and air breakdown are blocked, do not lose circle deformation when can support again epoxy fiberglass tubes flexural loading, add the rigidity of product, decrease bending deformation quantity.B, in epoxy fiberglass tubes 2 install insulation air bag 5, alleviate product weight, save raw material, reduce cost, the space that circle deformation is transferred in capsule can will be lost again when epoxy fiberglass tubes flexural loading, simultaneously because implant is less, reduce the different impact on product of bi-material swell-shrink coefficient, it is to avoid interface and solid material tear or the air gap of recoverable force formation not in place.
Insulation support plate 4 is made up of hard insulation, and shape can be according to mounting process requirement, and the insulation support plate installed under natural environment does not set steam vent, and the insulation support plate of vacuum mounting process is provided with steam vent.Insulation support plate circle of position shape, its diameter of phi 1 is identical with the internal diameter of epoxy fiberglass tubes 2, and according to the needs of different electric pressure products, its thickness d is 10 ~ 50mm.The two sides of insulation support plate 4 is respectively equipped with three Blind locating holes 4-1.
Insulation air bag 5 is made up of hard or semi-rigid insulant, needs according to different electric pressure products, the external diameter Φ 2 of insulation air bag is more smaller than epoxy fiberglass tubes, so as filling insulant, highly h is 1 ~ 5 times of Φ 2, upper and lower end is provided with three alignment pin 5-1, it is simple to insert Blind locating holes location during installation.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the structural representation of insulation support plate 4.
Accompanying drawing 3 is the structural representation of insulation air bag 5.
Detailed description of the invention
1,2 insulation support plate 4 is produced referring to the drawings；2, referring to the drawings 3, at 20 DEG C of constant temperature and humidity under the clean environment less than 50%, make insulation air bag 5, it is ensured that cleaning gas in air bag and be dried；3, epoxy fiberglass tubes is placed in sulphurated siliastic full skirt 3 in special mould；4, insulation support plate 4 is arranged on the lower end in the epoxy fiberglass tubes stood vertically with full skirt 3, the hole, the location alignment pin to good insulation air bag 5 bottom above gripper shoe, it is full of appropriate filling insulant, in the upper end of insulation air bag 5 to good dowel hole, another block insulation support plate 4 is installed.The most repeatedly, until all installing insulation support plate 4, insulation air bag 5 in whole epoxy fiberglass tubes, and insulant 6 is filled, after insulant to be filled solidification, install adnexa 1a and lower adnexa 7, i.e. make composite insulation cross arm, install adnexa 1b and lower adnexa 7, i.e. make compound inslation pillar.
