The utility model aims to provide a kind of anti-thunder insulator with rain and snow sheath, with what solve that prior art exists, special lightning arrester is set and increases the difficulty of investment and line upkeep; And the junction between insulator and power line is exposed in circuit very easily causes the corrosion of junction to damage, there is the problem of the requirement of potential safety hazard.
The technical solution of the utility model is: a kind of anti-thunder insulator with rain and snow sheath, comprise by insulating rod and be connected to the insulator that the several water-proof plates on this insulating rod form, top at this insulator is provided with binding clip, in the bottom of this insulator, is provided with metal screw and hold-down nut, a side below the binding clip of described insulator connects a reclinate lightning-arrest bar, in the lower end of this lightning-arrest bar, be provided with the discharge end towards insulator lower end, in the lower end of described insulator, be provided with the discharge head relative with the discharge end of the bar of taking shelter from the thunder, it is characterized in that, the junction of the binding clip on this insulator top and lightning-arrest bar and insulator is installed in a rubber sheath, this rubber sheath comprises the main body of the n shape that can hold described binding clip and insulator top, in the both sides of this main body, be provided with for the body through power line, below body at one end, be provided with for the lower tube body through the pole-footing portion that takes shelter from the thunder, part at this below body center is provided with minute tangent plane along body axis and main body axis, along the edge of this minute tangent plane, is provided with butt joint edge, at the opposite face of butt joint edge, is provided with several projections that cooperatively interact and jack.
Top at described body is provided with reducing.
Described binding clip comprises base plate, top board, screw rod and nut, and the bottom surface of base plate is connected with the top of the metallic object on described insulating rod top; Top board be located at base plate above, the middle part between top board and base plate is provided with arc groove, at least mutually fastening by two screw rods and nut between the top board of arc groove both sides and base plate.
The utility model has the advantages that: integrated lightning-arrest electric discharge mechanism on insulator, save other installation lightning arrester, simplified line construction, saved investment, reduced the maintenance difficulties of circuit, also overcome at insulator centre bore the shortcoming that lightning arrester causes strength decreased is set; The junction of the junction of insulator and power line and binding clip and ground loop is all enclosed in the rain and snow sheath of a rubber, has avoided extraneous sleet to corrode for a long time junction, has guaranteed the operation of power circuit long-term safety; Also effectively stopped the possibility of exposed junction electric leakage.Easy for installation, with low cost.
