Problems solved by technology
However, when defects such as lightning strikes and self-explosion appear in the "V" word tension insulator string, the difficulty and danger of live maintenance are very high. The two operating hooks completely hook the lower part of the tension insulator string, which is easy to unhook and cause safety hazards

The invention provides a replacement tool which is used for replacing a strain insulator string in a live-line manner. The tool comprises a clamp comprising a front clamping piece, a rear clamping piece and two extension rods connected between the front clamping piece and the rear clamping piece, and an insulator cradle used for supporting the strain insulator string, wherein the front clamping piece and the rear clamping piece are respectively and detachably clamped at a front fixed end and a rear fixed end of the strain insulator string, the front clamping piece is also provided with a penetration piece, one end of the insulator cradle is hinged with the rear clamping piece, and the other end of the insulator cradle can be controlled to extend into or out of the penetration piece, when the tension insulator string is disconnected with the front fixed end, the other end of the insulator cradle extends out of the penetration piece, and the insulator cradle supports the tension insulator string and can be controlled to pivot relative to the rear clamping piece. By applying the technical scheme, the effect of the live replacement of the strain insulator string can be achieved.
Description
technical field [0001] The invention relates to the field of tools for high-voltage transmission lines, in particular to an appliance for live replacement of tension insulator strings. Background technique [0002] The "V"-shaped strain insulator string is a key technology in compact line towers (such as 2202DZMV type, 220ZM type), which can effectively limit the swing range of the wire, and reduce the size of the tower head and the dynamic and static width of the corridor. , due to the short distance between the three-phase conductors, the natural transmission power and electromagnetic environment of the line are better than ordinary lines. However, when defects such as lightning strikes and self-explosion appear in the "V" word tension insulator string, the difficulty and danger of live maintenance are very high. The two operating hooks completely hook up the lower half of the tension insulator string, which is easy to unhook and cause potential safety hazards. Contents...
