The manipulator bar for installing clamps of measuring cables at the inputs of high-voltage equipment on overhead power lines

摘要

The utility model relates to the field of electrical engineering, namely to rods for attaching clamps of measuring cables to the inputs of high-voltage equipment located high above the ground on high-voltage power lines, without the use of stairs and elevators, also serves to facilitate the work and protect personnel involved in installation, maintenance and repair of electrical networks and switchgears. The technical result of the utility model is to simplify the process of manipulating the rod, namely, to reduce physical load on the worker when installing removable clamps due to structural changes of the rod itself. The manipulator bar contains an insulating rod, a handle with pins, a collet with holes, a connector for attaching a removable phase clamp. To manipulate the removable clamp, the rod is equipped with a rotary device and a cord, one end of the cord is fixed to the handle, and the other end is fixed to the connector for attaching the removable clamp. For reliable fixation of the cord from spontaneous unwinding when the hand intercepts the handle during manipulation, a spring is installed in the handle. In this case, the cord is mounted on rollers located on an insulating rod, a rotary device located in front of the connector, and on the connector. The connector is hollow in the form of a lever type grip made of bent steel sheet with flanges and consists of a fixed body, a movable lever, and a hollow rod connected motionless with the connector housing. The rod is used to connect the connector to the rotary device. To reduce physical stress during manipulation of the clip inserted into the connector, a roller is installed on the movable lever of the connector, and two rollers are installed on the gripping rod through which the cord passes, forming a chain block.
