Portable protection device for hot-line work

TLDR: In this paper, a portable protecting space for hot-line job is used in high-voltage and ultra-high voltage transmission wires of 110 kilo voltages and above 110k voltages, composed of insulation operating bars, insulation bars for installing electrodes, adjustable electrodes, fixed electrodes, conducting wire clamps and ground lead wire components.

Abstract: A portable protecting space for hot-line job is used in high-voltage and ultrahigh voltage transmission wires of 110 kilo voltages and above 110 kilo voltages and is composed of insulation operating bars, insulation bars for installing electrodes, adjustable electrodes, fixed electrodes, conducting wire clamps and ground lead wire components. With the employment of the utility model, the size of the head of a circuit steel tower is capable of being compressed, and the discharge voltage of the protecting space has stability, repeatability and recoverability without influences of the arrangement of conducting wires, insulator type, pole tower type, polar effect and the like. The utility model has the advantages that the protecting space can be adjusted deftly and is convenient for being detached, installed and transported, and is adaptable for outdoor and tower operation, thereby improving safe reliability of staff member working in hot-line job and ensuring the safety of wires and equipments.
