Embodiment
Inventor studies discovery, because insulated circuit has the lightning withstand level of inadequate natural endowment, is difficult to the effect of bearing direct lightning strike or induced lightening, does not install the built on stilts frame of lightning protection measures, when being struck by lightning, broken string can occur and porcelain insulator such as to burst at the problem.
Core of the present utility model is to provide a kind of insulator, while realizing being provided with lightning arrester in power distribution network, reduces unnecessary insulated conductor cut, improves the security performance of power distribution network.
In order to enable above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Set forth detail in the following description so that fully understand the utility model.But the utility model can be different from alternate manner described here to implement with multiple, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension.Therefore the utility model is not by the restriction of following public embodiment.
Please refer to Fig. 1 and Fig. 2, the insulator structure schematic diagram that Fig. 1 provides for the utility model embodiment; The front view of the insulator that Fig. 2 provides for Fig. 1.
A kind of specific embodiment of the present utility model provides a kind of insulator, comprising: insulator 1, and described insulator is provided with the full skirt 11 of preset number; Be arranged on the bite 2 of described insulator 1 one end, described bite 2 comprises the first bite 21 and the second bite 22, the cavity holding wire and pass through is provided with between described first bite 21 and the second bite 22, the inwall of described cavity is provided with conduction puncture tooth 23, and described conduction puncture tooth 23 penetrates the insulating barrier of described wire and the core of wire described in electrical contact; With the described lightning arrester 3 that tooth is electrically connected that punctures that conducts electricity.
When installing, only the first bite and the second bite need be separated, make wire through the cavity formed the first bite and the second bite, then the first bite is fastened in the second bite, conduction puncture tooth is made to penetrate the insulating barrier of wire, thus touch core, realize electrical connection, lightning arrester is connected electrically to the core of wire by conduction puncture tooth.When there is thunder-strike phenomenon; lightning arrester can play a good protection to wire; effectively avoid the generation of line tripping and the line-outage contingency caused by being struck by lightning; due to the insulating barrier adopting conduction puncture tooth to penetrate wire; namely have employed needling technique; need not the insulating barrier of strip off wire; can effectively avoid changing the broken of insulating barrier of line insulation wire; thus the damage avoided the core of insulated conductor and corrosion; ensure that the security of operation of circuit, make construction and installation simpler simultaneously.
