Abstract
The utility model provides a lightning stroke overvoltage protection type supporting insulator. The insulator comprises an insulator body, a lead wire connecting part at the upper end of the insulator body and a fixing part at the lower end of the insulator body. An arc extinction ball is fixed to the fixing part in a power-on manner. An arc striking rod is fixed to the lead wire connecting part in a power-on manner. One end of the arc striking rod is fixed to a base of the lead wire connecting part and extends downward in an air discharge gap hanging manner compared with the arc extinction ball. In the technical scheme, the arc striking rod of the lead wire connecting part and the arc extinction ball of the fixing part form a lightning stroke overvoltage discharge bypass, so that the supporting insulator can be effectively protected in case of a lightning stroke or an overvoltage. The supporting insulator is simple in structure.
Description
Technical field
The utility model relates to the supporting insulator in overhead power transmission, distribution line.
Background technology
The electric property of transmission of electricity, distribution line and protective value thereof require to improve gradually the development of the technology that promoting, and especially the insulation property upgrading of transmission of electricity, distribution line is more urgent.At present, in overhead distribution, lightning protection measures mainly contains overhead ground wire, mounting clamp clamp insulator, overvoltage protection device is installed on pillar insulator both at home and abroad, and load side is installed arc-preventing metal utensil.Due to transmission of electricity, there is the not enough electric mounting position of a large amount of resistance to thunderbolts in distribution line, be difficult to directly bear thunderbolt, struck off wire, insulator demolition, full skirt and because of arcing, the phenomenon such as hardening crack and become the technical barrier that electric power system faces.Wherein, in transmission of electricity, distribution line, a large amount of supporting insulators is installed, adopt above-mentioned lightning-protecting engineering means to have many technical problems such as amount of investment is large, installation complex operation, and lightning arrester installation needs wire insulation skinning operations, cause the technical problems such as core water inlet and corrosion, also can be subject to the impact of ring network power supply load side variation etc.
Summary of the invention
Goal of the invention of the present utility model be to provide a kind of have Lightning Over-voltage barrier propterty Lightning Over-voltage protection type post insulator.The Lightning Over-voltage protection type post insulator technical scheme that the utility model provides, its main technical content is: a kind of Lightning Over-voltage protection type post insulator, include insulator body, the wire interconnecting piece of insulator body upper end and the fixed part of lower end, fixed part conduction is fixed with extinguishing arc ball, on wire interconnecting piece, conduction is fixedly installed starting rod, starting rod one end is fixed on wire interconnecting piece pedestal, and to downward-extension, it is unsettled that relative extinguishing arc ball is atmospherical discharges gap.
In above-mentioned overall technical architecture, described starting rod is Transverse arm section, oblique arm section and the back bending section of Lian Xu, and it is unsettled that the back bending section top relative extinguishing arc ball of bulb is atmospherical discharges gap.
In above-mentioned overall technical architecture, described starting rod is provided with insulating sleeve skin, and the outer field lower end of the insulating sleeve mouth of pipe is towards extinguishing arc ball.
The disclosed Lightning Over-voltage protection type of the utility model post insulator technical scheme; be provided with the Lightning Over-voltage being formed by the starting rod of wire interconnecting piece and the extinguishing arc ball of the fixed part bypass of releasing; moment punctures the airspace between starting rod lower end and extinguishing arc ball; thereby protected the excellent of post insulator; the technical program has realized Lightning Over-voltage barrier propterty technical purpose, and its simple structure.
Accompanying drawing explanation
Fig. 1 is general assembly structure chart of the present utility model.
Fig. 2 is another embodiment structural map of the present utility model.
Embodiment
The disclosed Lightning Over-voltage protection type of the utility model post insulator, as shown in drawings, its composition includes the wire interconnecting piece 2 of insulator body 1, insulator body upper end and the fixed part 3 of lower end, the upper and lower end of insulator body 1 embeds respectively in the pedestal of electric wire connecting portion 2, fixed part 3, and three parts are fixed as one.Starting rod 4 is fixedly connected on the riffled tube 7 of a side of wire interconnecting piece 2 pedestals, and be connected with wire interconnecting piece 2 conductions, extinguishing arc ball 5 is fixedly installed on fixed part 3, and preferably and wire interconnecting piece 2 and riffled tube 7 in same lateral position, in the present embodiment, extinguishing arc ball 5 adopts cup head stainless steel nut, and screw-threaded coupling is fixed on fixed part 3 pedestals.Starting rod 4 is to downward-extension; as shown in drawings; starting rod 4 is the Transverse arm section of Lian Xu, downward oblique arm section and back bending section; back bending section top is bulb; this bulb is relative with extinguishing arc ball 5, and to be atmospherical discharges gap unsettled; both have formed the bypass channel of Lightning Over-voltage breakdown protection, and both relative air clearances are 130 ± 5mm.For more efficiently performance Lightning Over-voltage barrier propterty, starting rod 4 is arranged in insulating sleeve layer 6, and wire interconnecting piece 6 is arranged in sheath 6, and the outer 8 lower end mouths of pipe of insulating sleeve are towards extinguishing arc ball 5, relative with extinguishing arc ball 5.
