Technical Field
The invention relates to the technical field of live-line work of extra-high voltage lines, in particular to telescopic potential transfer rods for live-line work of extra-high voltage lines.
Background
The ultra-high voltage line has large transmission capacity and high reliability requirement, and does not have a temporary power failure condition, has critical defect, and needs to be treated by utilizing live working emergency elimination.
The potential transfer rod of the existing extra-high voltage strain tower has problems in the actual use process, brings fixed risk hidden troubles to live working, and influences the live working efficiency.
The existing potential transfer rod is 80cm in length and too large in size, and cannot be placed in a personal tool bag, and only can be positioned at the waist of an operator.
Disclosure of Invention
The invention aims to provide telescopic potential transfer rods for live-wire work of an extra-high voltage line, which are easy to operate, convenient to disassemble and assemble and reliable in connection.
In order to achieve the purpose, the technical scheme includes that the telescopic potential transfer rod for hot-line work of extra-high voltage lines comprises a telescopic insulating operation handle, an omega-shaped plug is mounted at the front end of the telescopic operation handle and electrically connected with a terminal connector through a copper wire coated with a copper wire sheath, the terminal connector comprises a C-shaped connecting seat and a screw rod, a threaded hole is formed in the upper side portion of the C-shaped connecting seat and in threaded connection with the screw rod, a pressing block is arranged at the lower end of the screw rod, a rotating handle is arranged at the upper end of the screw rod, the lower side portion of the C-shaped connecting seat faces the upper side portion of the pressing block, or a boss used for sleeving a copper wiring nose is arranged on the lower side portion of the pressing block, so that the copper wiring nose at the front end of a clothes connecting wire is firmly sleeved when the screw rod rotates.
, the telescopic handle is composed of multiple sleeves nested one inside the other and able to slide relatively.
, the omega-shaped plug is mainly composed of a copper terminal and curved copper clamping sheets connected to two sides of the copper terminal, wherein the copper terminal is installed at the front end of the innermost sleeve and is electrically connected with a copper wire penetrating out of the innermost sleeve.
, the copper wire covered with copper wire sheath is inserted into the nested multiple sleeves, end is passed out from the innermost sleeve and electrically connected with the copper terminal, and end is passed out from the outermost sleeve and electrically connected with the C-shaped connecting seat of the terminal connector.
, the height of the boss is matched with the thickness of the copper wire connecting nose of the clothes connecting line, so that the copper wire connecting nose is pressed when the pressing block presses the lower side part of the C connecting seat.
, the screw is detachably connected with the pressing block.
Compared with the prior art, the invention has the advantages that telescopic potential transfer rods which can be quickly assembled and disassembled with a copper connection lug and are reliably connected and have good conductivity are provided, the telescopic potential transfer rods can be quickly assembled and disassembled by one person through the potential transfer rods, the working efficiency of operators is improved, the time length of the extra-high voltage live working is greatly shortened, the circuit retreating and reclosing time is reduced, and the safety of the operators and a power grid is effectively improved.
