Description

A kind of 10kV Multifunctional disaster prevention evil insulator and preparation method
Technical field
The invention belongs to electrical engineering technical field, be specifically related to a kind of 10kV Multifunctional disaster prevention evil insulator and preparation side Method.
Background technology
Distribution network line be power system send out, defeated, become, join, by the important component part of system in five big subsystems, it holds Carrying on a shoulder pole the important task to sharing of load electric energy, its safe and stable operation is most important, but owing to the dielectric level of distribution line is low, net Shelf structure is simple so that it is do not have the ability of protection direct lightning strike.It addition, the induced lightening voltage that thunder and lightning produces on wire is the most significantly Exceed the dielectric level of distribution line.According to statistics, in the electrical network of 6~35kV electric pressures, lightning trip-out rate remains high, And often have the equipment such as on-pole switch, disconnecting link, spark gap, transformator, sleeve pipe to damage when lightening activity.Distribution network line suffers During thunderbolt, easily there is insulator arc-over electric discharge, cause insulator surface by electric arc burn, dielectric level is greatly reduced, seriously Time can cause conductor cord disconnection (wherein insulated conductor is easier to lightning-caused breaking than bare conductor), line outage.
On the other hand, being gone down south strong cold air and southwest warm moist air joint effect by the north, south China part province goes out Existing powerline ice-covering disaster, and owing to the circuit whole height of distribution is low, circuit is distributed mainly on surrounding city, and distribution supplies Electrical stability be relatively vulnerable to branch drop, birds droppings, filth, the impact of heavy rain etc..Operating statistic data show, power distribution network is because of thunderbolt The insulator arc-over caused with icing causes tripping fault to account for the 70% of power distribution network tripping fault sum.These disaster accidents show: For improving existing transmission line of electricity safe operating conditions, carry out professional circuit and take precautions against calamities technical work, strengthen transmission line of electricity and prevent The research of lightning stroke trip, ice-covering-proof flashover, anti-pollution flashover etc., develops the power distribution network insulator with anti-multiple disaster function It it is the current important topic be badly in need of and solving.
There is following defect and deficiency in the lightning protection anti-ice-flashing composite insulator of related invention patent 201510376532.X:
1) do not account for the anti-bird pest of insulator, the function such as branch drops, heavy rain, insulator integral insulation under this type disaster Can decline, be difficult to ensure for electrical stability;
2) its cluster parachute and sparking electrode size do not optimize design, discharge electrode structure design existing defects, icing electric discharge in period There will be bridge joint between electrode, insulating segment lost efficacy, the aging aggravation of arrester valve piece, and lightning protection anti-ice-flashing effect declines.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency overcoming prior art to exist, it is provided that one can effective pre-lightning protection, The multiple disasters such as ice, heavy rain, filth, birds droppings, simple installation, length in service life, it is easy to existing transmission line of electricity is transformed 10kV Multifunctional disaster prevention used for transmission line evil insulator.
For solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of 10kV Multifunctional disaster prevention used for transmission line evil insulator, puts including circular arc type wire casing gold utensil and the rod type being bent upwards Electricity electrode, compound inslation sub-component, insulation umbrella cover, plug, steel foot gold utensil, described compound inslation sub-component includes being sheathed on successively Lower conductive cushion block, metal oxide resistance group, middle conductive cushion block, cross-over block and the upper conduction on plug and being mutually close to Cushion block, described insulation umbrella cover is wrapped in composite insulator component external, sets between described compound inslation sub-component and insulation umbrella cover Having insulating barrier, described circular arc type wire casing gold utensil to run through insulation umbrella cover to threaded with upper conductive cushion block, described steel foot gold utensil runs through Insulation umbrella cover threaded with lower conductive cushion block, the two ends of described plug respectively with circular arc type wire casing gold utensil and steel foot gold utensil phase Connecing, be cross-over block between described upper conductive cushion block and middle conductive cushion block, the connection of described middle conductive cushion block has to run through stretches out To insulation umbrella cover outside be bent upwards rod type sparking electrode, described circular arc type wire casing gold utensil be bent upwards rod type sparking electrode Between leave the air gap.
Described circular arc type wire casing gold utensil is umbrella and entirety covers the rod type sparking electrode being bent upwards, namely circular arc molded line Groove gold utensil entirety extension elongation size stretches out size, circular arc type wire casing gold utensil end more than the rod type sparking electrode being bent upwards The end that edge and the rod type sparking electrode being bent upwards are bent upwards leaves one section of distance tilted.
As improving further and supplementing for technique scheme, the present invention uses following measure.
