(9)The insulator that will be disengaged from bowl head with transmission rope delivers to ground, and new insulator transmission rope is mentioned on bar;
(10)No. 1 electrician and No. 2 electricians cooperate and one end of new insulator are arranged on bowl bulb hanging ring on bar, first-class spring Pin, the other end of new insulator is arranged on strain clamp and is fastened, and removing turnbuckle makes wire relaxes;
(11)Remove Work tool and pass ground back by transmitting rope;
(12)Masking of No. 1 electrician to adjacent conductors, insulator, cross-arm insulation is removed on bar;
(13)Lower beam after situation on operating personnel's inspection bar, operation is finished.
10. the method for changing distribution line strain insulator as claimed in claim 9, it is characterised in that:The fixing-line device bag Card line main body and the connector and elastic spacing mechanism that are attached to are included, connector is used for attended operation bar, and operating personnel is led to Crossing action bars ground potential operation is connected with connector makes card line main body clamping wire, and elastic spacing mechanism blocks card line main body to lead Self-locking improves security after line;
Card line main body includes stationary body and is hinged active agent thereon, and stationary body and active agent are high intensity aluminium Alloy die forging is formed, and cable clamping interface is arranged at the bottom of stationary body, and the downside of active agent coordinates with cable clamping interface blocks wire, and activity is main One end of body is hinged with handle, and stationary body correspondence handle has bar-shaped trough at position, and handle is passed through from bar-shaped trough, by drawing Hand applies external force to realize the folding of active agent, and elastic spacing mechanism is vertically connected on handle;
Elastic spacing mechanism includes fixed column, spring and steel ball, and there is blind round hole at the length direction center of fixed column, and spring is placed in In blind round hole, steel ball is fixed on the outer end of spring, and spring can freely stretch with steel ball in blind round hole, and fixed column is circle Post, it has screw thread with the connection end outer wall of stationary body;The peripheral edge portion of steel ball is all stretched out in outside blind round hole;
Physically there is a screwed hole corresponding with fixed column connection end the bar-shaped trough side of stationary body;The peripheral edge portion of steel ball or All stretch out in the bar-shaped trough on stationary body at home and abroad;The connection for attended operation bar is connected with the downside of stationary body Head;Connector includes cylinder and the attachment structure perpendicular to cylindrical sidewall, and the upper end of attachment structure is to connect with stationary body The external screw thread head for connecing, one end of cylinder is plum blossom bond structure;There is the U-type groove perpendicular to side wall on the downside of cylinder;
Limiting plate is hinged with relative to the offside of elastic spacing mechanism on active agent, there is connection ring the upper end of limiting plate.
