Description
Technical field
The present invention relates to a kind of anti-rat snake devices of distribution line.
Background technology
Domestic and international distribution line external force is destroyed, be always one all the year round since pendent problem.Wherein, very one big
Exceptionally broken failure cause is that the climbing of rat snake class causes caused by line short.With the increasing of outer broken accident number, coverage
Expansion, the outer broken problem of distribution line caused enough attention.
For electric line protection against rodents class climbing safeguard procedures traditional at present, mainly using anti-snake thorn, bird-scaring unit dress
It sets, protection against rodents this part there is no effective solution method.Reinforce with the protection of greening environment, the probability that rat snake occurs will increasingly
It is more.And general anti-snake device pierces mainly by anti-snake and prevents class climbing, but class can many times be shone into injury, thus
The ecological balance of location is influenced indirectly.Although nearly 100% insulating is handled current 10kV distribution lines, on circuit
The main reason for some fuses, bar knife remain unchanged there are bare spots, also become 10kV distribution line failures.Institute is to prevent snake thorn device
It is outer broken caused by rat snake climbing without fundamentally solving the problems, such as, and the insulation measures of bar knife cutter head exposed section design at present are deposited
The bar knife critical component installed in larger difficulty, circuit " must ensure that conducting element has reliable insulation against ground, bears conduction
The supporting insulator of the operating force of element and various external force ", but the insulation distance of current bar knife cutter head exposed section only has
170mm, hence it is evident that it is less than 200mm dry arcing distances, though circuit normal operation is not influenced under normal circumstances, but as long as slightly there is foreign matter
(such as rat snake, branch) easily causes insulation distance shortening to lead to insulator arc-over and make line tripping, in addition the bar on circuit
Knife, because its moving contact is that rotation carrys out divide-shut brake at pedestal on lower side, conduction contact part can be fixed, design personalized insulating boot
The conductive exposed part such as bar knife is carried out to cover the settling mode that insulating processing is best.
