Abstract
The invention provides a lightning overvoltage protective post insulator which comprises an insulator body, a lead connecting part and a fixing part, wherein the lead connecting part is arranged at the upper end of the insulator body; the fixing part is arranged at the lower end of the insulator body; an arc extinction ball is conducted and fixed with the fixing part; a starting rod is conductively and fixedly arranged on the lead connecting part; one end of the starting rod is fixed on a base of the lead connecting part, extends downwards, has an air discharge gap with the arc extinction ball and is suspended relative to the arc extinction ball. Through the arrangement of the post insulator adopting the technical scheme, a lightning overvoltage discharge bypass comprises the starting rod on the lead connecting part and the arc extinction ball on the fixing part, so that the post insulator is effectively protected in case of lightning or overvoltage, and the lightning overvoltage protective post insulator adopts a simple structure.
Description
Technical field
The supporting insulator that what patent application of the present invention related to is 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 to promote the development of technology, and especially the insulation property upgrading of transmission of electricity, distribution line is then more urgent.At present, in domestic and international overhead distribution, lightning protection measures mainly contains overhead ground wire, mounting clamp clamp insulator, on pillar insulator, installs overvoltage protection device, and load side installs arc-preventing metal utensil.Due to transmission of electricity, there is the not enough electric mounting position of a large amount of resistance to thunderbolt in distribution line, be difficult to directly bear thunderbolt, struck off wire, insulator demolition, full skirt the phenomenon such as to hardening crack because of arcing has become the technical barrier that electric power system faces.Wherein, in transmission of electricity, distribution line, a large amount of supporting insulators is installed, the many technical problems such as amount of investment is large, installation complex operation that adopt above-mentioned lightning-protecting engineering means to exist, and lightning arrester installation needs wire insulation skinning operations, cause the technical problems such as core water inlet and corrosion, also can by the impact etc. of ring network power supply load side change.
Summary of the invention
The goal of the invention of patent application of the present invention 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 patent application of the present invention 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, relative extinguishing arc ball is that atmospherical discharges gap is unsettled.
In above-mentioned overall technical architecture, described starting rod is Lian Xu Transverse arm section, oblique arm section and back bending section, and back bending section top bulb is that atmospherical discharges gap is unsettled relative to extinguishing arc ball.
In above-mentioned overall technical architecture, described starting rod is provided with insulating sleeve skin, and the insulating sleeve outer field lower end mouth of pipe is towards extinguishing arc ball.
Lightning Over-voltage protection type post insulator technical scheme disclosed in patent application of the present invention; be provided with the Lightning Over-voltage be made up of the extinguishing arc ball of the starting rod of wire interconnecting piece and fixed part to release bypass; puncture the airspace between starting rod lower end and extinguishing arc ball instantaneously; thus protect the excellent of post insulator; the technical program achieves Lightning Over-voltage barrier propterty technical purpose, and its simple structure.
