Background technology
Electric insulator strain clamp string is the important component part of power transmission and distribution overhead power line, it not only directly has influence on fail safe, the reliability of power circuit operation, and affect economy, the feature of environmental protection of electric line operation to a great extent, and the useful life of whole circuit, so how design and evaluation, can be used for insulating energy-efficient, the environmental protection of transmission and distribution circuit, the electric insulator strain clamp string of safety, is key subjects anxious to be resolved of China's power grid construction.Especially how preventing arc how easily not peeling just can set up reliably insulated wire how easily electrical verification ground connection how more automatically effectively to grip in the problems such as wire, the product all needing a kind of innovation is old before replacing has continued to use defective old product for many years.Known power transmission and distribution overhead transmission line, in the past be all plain conductor, start distribution line after the nineties and use insulated conductor gradually.Insulated conductor solves the safety problems such as the line corridor that plain conductor originally has, the known distribution line class of insulation is relatively low, in actual use due to lightning-caused breaking, insulator is damaged, the situation making whole electric line produce operation troubles happens occasionally, especially due to global weather change, often there is thunderstorm weather, the meteorology that lightning flashes and thunder rumbles is more frequent, therefore the electric network fault caused has accounted for 36.8% of whole line fault, and wherein lightning-caused breaking rate accounts for 96.8%, greatly have impact on the normal power supply of gauze, the loss caused to national economy is also very considerable.Japan just once studied at early seventies and reached a conclusion: if insulated conductor does not have appropriate lightning protection measures, was will inevitably break and insulator breakage when so running into thunderbolt.Therefore insulated conductor must be solved by lightning-caused breaking, the problem of insulator breakage, the safe operation of guarantee overhead insulating transmission and distribution network.Known method, has installation overhead ground wire, and zinc oxide arrester etc., but still there is great hidden danger.Recently, straight line pole place preventing arc has good method, and as lightning protection pillar insulator, but the special strain clamp insulator string preventing arc in the place such as tension-resistant rod, terminal pole, extension bar does not also have, therefore be badly in need of will inventing one effectively, be conveniently adapted to the puncture type arc-protection strain insulator-string of various installation situation.
In addition, during known power transmission and distribution overhead transmission line erection, equipment used is mostly traditional old-fashioned power equipment, not only stupid but also large, install complicated, purchase numerous and diverse, poor safety performance, and the wire clamp of clamping wires is all fixed on the cross-arm of electric pole by single insulator and connection gold utensil, both the security performance of taking precautions against thunderbolt had been lacked, again can not reliably clamping wires lastingly, there is great hidden danger.Some energy-consuming products fallen behind all widely use so far in China always, the electrical network at different levels throughout urban and urual areas of whole country.
A kind of lightning protection strain insulator string (200910047802.7), the problems such as this invention substantially solves volume heaviness, do not need peeling, function is many.But what this invention adopted is tapered wire clamp, is connected with adopting U-shaped draw ring between anti-thunder insulator, tapered wire clamp puncture body is connected with also needing an external wire between anti-arc insulator starting rod.Many external wires can cause installation constant, increasing link easily occurs with many fault points, if adopt original wedge shape strain clamp, because chucking power is limited, clamping insulated conductor, easily cause the problem that wire slip is loosed core, so many power departments require that insulated conductor must peeling be arranged on strain clamp, considerably increase the workload of installation and the damage to wire.
Therefore we are under this technical background, have invented a kind of more advanced puncture type arc-protection strain insulator-string.
Summary of the invention
Object of the present invention, it is exactly the power grid construction for adapting to China's development, all disadvantages of the old-fashioned power equipment of thorough change, design and develop out a kind of power transmission and distribution overhead transmission line, there is preventing arc insulation function, electrical verification grounding function, puncture conducting function and fixed clamp and hang and pull and support wire function, and the puncture type arc-protection strain insulator-string of the omnidistance insulation function of power transmission and distribution can be accomplished.
Technical scheme of the present invention is such:
At lightning-proof suspension insulator 4 (see the patent No.: left end 200920068156.8), connected as one by twin sockets link plate 5 and wedge shape strain clamp housing 1, cable rack ceases to be busy is through wedge shape strain clamp housing 1 and puncture wedge cutting 2, first utilize the pressure compaction cable rack ceases to be busy of puncture wedge cutting 2, then hooks the shape use torque nut 7 between compact heap 3 that punctures cable rack ceases to be busy is punctured to clamp in one end of puncture wedge cutting 2 and scale, at this moment because the clamping of penetrating cable clamp and puncture effect, cable rack ceases to be busy is communicated with conduction with strain clamp housing 1 and puncture wedge cutting 2, made one end and the starting rod conduction of lightning-proof suspension insulator 4 by twin sockets link plate 5 simultaneously, the discharging gap that one fixing is had between two starting rods of lightning-proof suspension insulator 4, in time having lightening strikes, this discharging gap, inevitable prior to insulator body release electric arc, thus serve the effect preventing lightning-caused breaking and protection insulator.One end that scale hooks shape puncture compact heap 3 is designed with steelyard hook shape, is hooked on one of them bolt, simultaneously as bolt fixing hole, is convenient to install.Puncture wedge cutting 2 with scale hook shape puncture the metal ratchet of compact heap 3 except being struck by lightning time overcurrent striking effect except, itself and insulated conductor to sting the power of holding very large, thus significantly increase the frictional force between wire clamp and insulated conductor, solve the problem that insulated conductor slip is loosed core.
When the present invention works, as long as be directly fixedly connected on the cross-arm of electric pole by connecting metal bolt, just can meet preventing arc, electrical verification, puncture conduction, grip and hang pull and support, the multi-functional technical requirement such as comprehensive insulating protection.Structure of the present invention is simple, complete function, easy construction, efficient energy-saving, is a kind of comprehensively power equipment renewal product.
