Description

Two-way lightning protection pillar insulator
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to a kind of two-way lightning protection pillar insulator.
Background technology
In order to reduce the overhead distribution fault that external causes such as trees, birds, accumulated snow cause, improve power supply reliability, developed country gradually adopts suspended insulated guide wire from the later stage in the sixties in the world.China begins that from the eighties city overhead distribution net is implemented insulating and transforms pilot, and the nineties begins to promote the use of.
Insulated conductor has solved corridor that plain conductor can't resolve and safety problem really, compares with cable, reduced investment, builds soon, and advantage is fairly obvious.But the lightning-caused breaking problem is but very outstanding.For example, 1998, lightening activity was strong, the 10KV insulated overhead line generation lightning-caused breaking of Beijing Power Supply Bureau's administration 14 times.Therefore, the lightning-caused breaking problem must be properly settled, the safe operation of overhead insulating power distribution network could be guaranteed.
The lightning-caused breaking principle of insulated conductor has been compared obviously different with plain conductor.When direct lightning strike or lightning induced voltage act on plain conductor and cause insulator arc-over, the power frequency short circuit current electric arc that continues moves to deviating from the power supply direction along lead under the effect of a power, lead is very little by the probability of serious burn, breakdown insulating barrier is a pin hole shape, the group that the power frequency short circuit current electric arc that continues is subjected to insulate is on every side coagulated, the arc root can only will fitly be blown at extremely short time inside conductor in the burning of pin hole place.
According to the principle of above-mentioned insulated conductor lightning-caused breaking, the corresponding precautionary measures have " dredge and stop up " dual mode." dredging " is exactly with near the local bare wireization of the insulated conductor the insulator, make power frequency arc arc root shift or be fixed on the special gold utensil and burn, thereby guardwire avoids burn.For example, peeling off insulating barrier at insulator and wire coupling place adopts arc protection type present price or the insulated conductor of insulator both sides is peeled off one section insulating barrier and installed the preventing arc wire clamp additional." obstruction " is exactly to stop the power frequency continued flow starting the arc behind the lightning stroke flashover.For example, adopt the current-limiting arc-extinguishing angle, i.e. the ring-like external series gap metal oxide arrester of band series connection.
Though above-mentioned dual mode can prevent lightning-caused breaking effectively, there is following deficiency:
1, present existing arc-preventing metal utensil, in use, insulated conductor need be peeled off length, and exposed part is bigger, and this can have certain influence to the sealing and the insulation of lead.
2, use lightning arrester, though protection effect is good, the construction and installation complexity, investment is big.
