Abstract
A composite insulator, which is provided with annex with climbing increased covers on the upper part and the lower part, relates to a composite insulator that is arranged on the electric locomotive roof. The upper and the lower annexes of the insulator are covered by climbing increased covers. The upper climbing increased cover extends out of the lower part of the upper annex, protruding inward. The lower climbing increased cover has a hollow boss corresponding to the circular installation hole of the lower annex. The utility model is provided with an upper and a lower climbing increased covers in the upper and lower annexes of the composite insulators, which make the original electric conductor annex become a good insulator which possess the arc of resistance, the hydrophobic performance and good antifouling performance owing to the insulation property of the climbing increased covers. Under the strict height limitation, the roof insulator increases the climbing electricity distance and arc distance by 20-35% while improving the antifouling voltage about 30%, so as to achieve the purpose of guaranteeing the safe operation. If the climbing distance needs to be enlarged, the upper and/or lower climbing increased covers can be provided with skirt rim outside. The utility model has the advantages of novel design, reasonable structure, scientific selecting material, safe and energy saving.
Description
Technical field
The utility model relates to the composite insulator that a kind of electric locomotive roof is adorned.
Background technology
Electric locomotive operates under the different air environment and climatic conditions, and the insulator on its roof is subjected to various pollutions, as coal smoke, oil smoke, chemical pollution, dense fog, icing, accumulated snow, light rain, dust and greasy dirt etc.Insulator surface lining one deck dunghill, dunghill forms electric pathway on the surface of insulator, makes the insulating power of insulator reduce greatly, and flashover takes place, and has caused serious threat for the safe operation of locomotive.And the roof insulator can not adopt its height of increase to improve the method for arcing distance and creep distance owing to be subjected to strict limitation in height.The utility model provides a kind of efficient ways for addressing the above problem.
Existing with the patent application of the upper and lower installation accessories leak free of insulator, as " a kind of organic composite insulator that is applicable to ultra-high-tension power transmission line " (patent No. 00260164), constitute by plug, umbrella cover and two ends gold utensil, in plug two ends and gold utensil junction, adopt hot pressing to annotate mode, make it to form a silicone rubber seal cover." composite insulator that the body that is tightly connected is arranged on a kind of gold utensil " (patent No. 00257543), there is bulb in dress awl chamber on the external end of composite insulator on ball residence, between awl chamber and the compound inslation daughter, the gold utensil body that is tightly connected is housed outside boring the chamber." a kind of composite insulator of compression type end seal structure " (patent No. 99255536), comprise and connect gold utensil, plug and outer insulation jacket, sealed end also comprise seal ring be connected the seal ring overcoat that gold utensil is complementary, the seal ring overcoat make seal ring with outer insulation jacket, be connected gold utensil, sealant closed contact.They only play the leak free effect, and the effect that does not improve creep distance, arcing distance and dirty withstand voltage.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of energy and improves creep distance, arcing distance, and the upper and lower installation accessories band that dirty withstand voltage value is high increases the composite insulator of climbing cover.
The implementation of the utility model purpose is, upper and lower installation accessories band increases the composite insulator of climbing cover, be with upper and lower increasing outside the upper and lower annex 2,6 of composite insulator 5 and climb cover 1,8, on increase and climb cover and 1 grow annex 2 lower ends, inwardly have and protrude 3, increase down and climb cover 8 and have and the interior empty boss of the cooresponding circle of play annex mounting hole.
The utility model adds at the upper and lower annex 2,6 of composite insulator 5 and adorns upper and lower increasing and climb cover 1,8, makes to be that the annex of electric conductor becomes and has arc resistance, hydrophobic nature and anti-fouling flashover performance good insulation performance body owing to increasing the insulating effect of climbing cover originally.Make the roof insulator under the limitation in height of strictness, increase its creep distance and arcing distance 20-35%,, improve dirty withstand voltage about 30%, reach the purpose of guaranteeing locomotive safety running.
The utility model modern design, rational in infrastructure, selection science, safe and reliable, energy savings.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
With reference to accompanying drawing, be with upper and lower increasing outside the upper and lower annex 2,6 of the utility model composite insulator 5 and climb cover 1,8, on increase and climb cover and 1 grow annex 2 lower ends 8 ± 5mm, inwardly have and protrude 3, so that with the identical overlapping suit of silaatic skirt cover of insulator, prevent that rainwater from infiltrating the inner bonding interface 4 of insulator.Upper and lower increase climb the cover 1,8 wall thickness be 3-8mm, optimum wall thickness is 4 ± 1mm.Add large distance as need, above and/or under increase and climb the cover 1 and/or 8 outer full skirts that also have.
Under increase climb cover 8 have with the cooresponding circle of play annex mounting hole in empty boss, this be the nut chamber, nut 7 is fixed on insulator on the roof, under increase to climb and overlap 8 and can prevent to discharge at nut 7 places.
Upper and lower increasing climbs cover 1,8 and made by silaatic or EP rubbers edge material, is preferably silaatic.
Upper and lower increasing climbs cover and also can be installed on the installation accessories of compound inslation pillar on various disconnecting links, the switch or porcelain strut insulator.
