For this reason, the utility model adopts following technical scheme: the spacing gold utensil of wire composite suspension insulator string windage yaw, comprises body and lower body, it is characterized in that,
The top of described upper body has one for the connecting hole with cross-arm Bolted angle connection, and the stopper slot of a both ends open is formed at bottom, and the notch of this stopper slot down; The top of lower body is placed in stopper slot and is coupling with the bottom of upper body, the running clearance that one can control lower body deflection angle is formed between the top of lower body and the bottom land of stopper slot, when the deflection angle of lower body reaches setting limited angular, the top of lower body and the bottom land of limited groove block.
The utility model changes the connection tower mode of conventional wires suspension string, upper body is fixedly connected on tangent tower cross-arm angle steel, lower body is rigidly connected composite insulator, the reserved running clearance that can control lower body deflection angle on spacing gold utensil, when wire is under strong wind wind action, namely suspension string lower end composite insulator is stuck after rotating and reaching setting limited angular, remain a small amount of wire wind load to be born by composite insulator bending resistance, achieve the object being carried out pilot windage yaw angle by spacing gold utensil.
Further, described setting limited angular is preferably 25-35 °.
Further, the top of described lower body is trapezoidal, oval, square or rectangular, as long as the bottom land of the limited groove of energy blocks when lower body turns to setting limited angular.
Further, the top of described lower body is preferably big up and small down trapezoidal.
Further, lower body is formed a circle instruction bulge loop, the lower body be positioned at below instruction bulge loop forms one for inserting the insertion groove of composite electric insulator core bar.Instruction bulge loop is used to indicate the insertion position of composite electric insulator core bar.
Further, the bottom margin of described lower body forms the connecting portion being used for crimping with composite insulator outer layer insulation rubber.
Further, the middle part of described upper body forms the step being used for locating with cross-arm angle steel, and body is fixed on cross-arm angle steel.
The utility model changes the connection tower mode of conventional wires suspension string, achieves the object being carried out pilot windage yaw angle by spacing gold utensil; By restriction wire windage yaw angle, effectively control suspension insulator generation windage yaw discharge, ensured the safe and reliable operation of transmission line.
