Abstract
By using a partition-type hollow composite insulation pillar, an innovative point is characterized in that an enclosed-type bottom of a partition sleeve 4 can block surface discharging caused by a leakage current of an inner wall of an epoxy glass fiber tube 2 and can separate air connection in the tube. The partition sleeve 4 is made of a rubber. A thickness of a bottom 4-3 is 3-4mm. An outer wall of the partition sleeve 4 is provided with an embossed circular ring 4-1 and a glue coating surface 4-2. An outer wall of the partition sleeve 4 and an inner wall of the epoxy tube 2 are pasted firmly by using a mucilage glue. A water film formed through water molecule ''condensation'' in the air in the partition sleeve is flowed to an upper end surface of the bottom of the partition sleeve and the water film can not be flowed to an upper portion and a lower portion. The partition sleeve 4 is made of the insulation rubber, can carry out heat expansion and cold contraction along with the epoxy tube and can be expanded and contracted along with bending, torsion and deformation of the epoxy tube. Influences of different materials and different expansion coefficients on a bonding interface are avoided.
Description
Technical field
The present invention relates to high-voltage composite insulator field.
Background technology
The purposes of composite insulator can be divided into three kinds: 1, suspended compound insulator, for hanging wire; 2, hollow combined insulator, also known as compound insulating sleeve, in-built electric component, and blanketing gas, liquid or solid insulating material, as electric equipments such as instrument transformer, lightning arrester, transformer, switches; 3, compound inslation pillar, for bus bar, the support of the equipment such as isolation switch.
Suspension type and hollow combined insulator because of cost close with porcelain insulator product, large scale application.And compound inslation props up major gene by production technology restriction (can not produce diameter and be greater than 130mm plug), and manufacturing cost is high, thus fails large scale application.Particularly 220KV and above electrical voltage system, substantially or the dominance of porcelain strut insulator.Current development 220KV and above compound inslation pillar have following several method: 1, porcelain compound: using porcelain knob as plug, the coated silicon rubber umbrella skirt cover in outside, and its mechanical performance is suitable with porcelain strut insulator, and major defect is that manufacturing cost is high, and anti-seismic performance is poor; 2, be wound around epoxy glass outward at pultrusion solid bar, successively increase diameter of mandrel several times, its subject matter is that cost is high, and layering shaped interface may exist air gap, causes infiltration defect; 3, fill insulating gas in epoxy fiberglass tubes, whether the necessary external air gauge of this product, leak in order to gas in long term monitoring pipe, considerably increase the maintenance workload of operation department, and user is difficult to accept; 4, filled polyurethane foam in epoxy fiberglass tubes, people query this material may there is partial discharge under High Voltage electric field action.The coefficient of expansion of foamed material and epoxy tube bi-material is inconsistent, bonding plane may be caused the to produce doubt that air gap problem also causes people of prolonged and repeated bending or variations in temperature, and in addition, the cost of major diameter epoxy tube filled and process is also higher; 5, inner wall increasing-climbing type: the multiple projecting annular bodies with axes normal are set in epoxy tube, make to become curve (namely increasing the creepage distance along inside pipe wall) with the epoxy tube inwall of axes normal by straight line.It improves the insulation level of epoxy tube inwall creeping discharge, but do not increase the atmospherical discharges distance in pipe, air breakdown insulation level can not be improved.
Summary of the invention
The present invention is directed to the problems referred to above, aim to provide a kind of environmental protection and energy saving, labor and material saving, easily manufactured, with low cost, completely cut off inner air tube electric discharge partition Hollow Compound insulation column.
Partition Hollow Compound insulation column is made up of upper annex 1, epoxy fiberglass tubes 2, external shed 3, partition cover 4 and lower annex 5.
Innovation of the present invention be cut off cover 4 enclosed type bottom 4-3 both creeping discharge of causing of epoxy fiberglass tubes 2 inwall leakage current capable of blocking, can cut off again that inner air tube is through to be punctured.Partition cover 4 rubber makes, and its shape resembles an isometrical cup of stockless, and bottom it, the thickness of 4-3 is 3-4mm, cuts off the external diameter φ 3-4mm less of epoxy fiberglass tubes internal diameter of cover pipe coated face 4-2, and its height h is 1-2 times of its diameter.The outer wall cutting off cover 4 has several protruding circular rings 4-1, and the height of projection of annulus is 1.5mm, and width is 5mm.When being loaded in epoxy fiberglass tubes by partition cover 4, protruding circular ring contact epoxy inside pipe wall, makes partition overlap pipe coated face 4-2 and does not rub with epoxy tube contact internal walls and wipe viscose glue.Protruding circular ring surface not coating viscosity glue and the non-bonding plane of 5mm width that formed is hoop instead of longitudinal direction, does not affect the interior insulation property (as the steel cap bulb of suspended porcelain insulator does not affect the insulation property of porcelain insulating substring) of product.Cut off a kind of special glue of the outer wall of cover 4 and the inwall of epoxy tube 2 firm, the moisture film formed time hydrone " condensation " that make each cut off in cover in air flows to the upper surface cutting off 4-3 bottom cover, does not allow moisture film upper and lower through.Each thickness cutting off cover bottom 4-3 is 3-4mm, 30-40KV voltage can be tolerated, after cutting off the end to end assembling of cover 4, bottom it, 4-3 forms multiple insulating course in epoxy tube 2, just can block power-frequency overvoltage and thunder and lightning or operating impulse voltage by the air breakdown in epoxy tube.Cut off cover 4 electro-insulating rubber to make, because rubber has elasticity, can expand with heat and contract with cold with epoxy tube, also can be flexible with the distortion of epoxy tube flexion torsion, avoid the impact on bonding interface that the different coefficient of expansion of different materials causes.Silicon rubber is because there being good hydrophobicity, and resistance to ag(e)ing and insulating properties, can be used as to make and cut off cover preferred material.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is the structural representations cutting off cover 4.
Embodiment
1, with reference to accompanying drawing 2, with mould, silicon rubber is supported cup-shaped and cut off cover 4, and with sand paper, circular outer wall coated face 4-2 is polished coarse, dry with after acetone cleaning; 2, the inwall of epoxy fiberglass tubes 2 is polished into matsurface, with uniform application viscose glue after acetone cleaning; 3, be enclosed within and insert in epoxy fiberglass tubes 2 by cutting off cover 4 outside a special air bag, be 0.4-0.8Mpa to airbag aeration to pressure, the outer wall that partition is overlapped and the inwall of epoxy tube are closely pasted.Air pressure keeps 24 hours, after viscose glue solidifies completely, takes out air bag.The next partition is installed according to the method described above overlap, makes it join end to end, cut off cover until all fill in whole epoxy fiberglass tubes; 4, sulphurated siliastic full skirt 3 in compound inslation supporting post mould is placed in by being equipped with the epoxy fiberglass tubes 2 cutting off cover 4; 5, annex 1 and lower annex 5, i.e. cost product processed is installed.
