A kind of charged disconnecting lead-in wire arc-extinction device is characterized in that: comprise wire clamp and extinguishing arc coaster,

Described extinguishing arc coaster includes hook, opening part at hook is provided with lock plunger, the bottom that is used for fixing fixation side at hook is provided with fixed pulley, open side at hook is hinged with lock plunger, offer the through hole that extends along the short transverse of fixation side in the hook fixation side, described lock plunger passes through hole and stretches out in outside the through hole when pinning the hook opening, through hole on hook fixation side lateral surface is provided with grab, described grab is hinged on the fixed block, grab can along with the perpendicular plane swing of lock plunger, the top of described fixed block is provided with fastening screw, lateral surface on the through hole top of linking up with fixation side is fixed with a nut, fastening screw is through on the nut to hang fixed block and grab, is provided with the suspension ring of handled easily bar operation on the top of hook;

Described wire clamp includes two to embracing arc-like sheet together, one open side of arc-like sheet is hinged, be provided with two clamping screws on one of arc-like sheet of another open side of arc-like sheet, this clamping screw is hinged on the arc-like sheet, clamping screw swings along the swaying direction of arc-like sheet, respective side at another arc-like sheet is provided be used to the open slot that snaps in clamping screw, clamping screw is used nut check after snapping in open slot, the inboard place of arc-like sheet one of therein also is provided with a little arc-like sheet, this arc-like sheet is threaded connection part and is bolted on the arc-like sheet, and this little arc-like sheet and another arc-like sheet are to embracing thirty years of age.

The charged disconnecting lead-in wire arc-extinction device of this structure, opening by hook is suspended on the wire, rear rotation lock bolt makes it pass the through hole on the hook fixation side and it is stuck on the grab, then drive fixed block and the grab motion that connects thereon by rotating fastening screw, thereby until wire is locked, owing to thereby grab can move up and down so that the space size between lock plunger and the hook top changes, thereby can make it be applicable to different wires.Again with the copper cash of extinguishing arc rope part, pass the pulley of extinguishing arc coaster, be fixed on the drainage thread with wire clamp behind a circle in the drainage thread end.Two arc-like sheets that are fixed as wire clamp of described drainage thread on wire clamp open, the extinguishing arc wire clips is entered between two arc-like sheets, after again two arc-like sheets are stuck on the drainage thread, the locking clamping screw is then adjusted little arc-like sheet again and is made it compress the copper cash part of drainage thread and extinguishing arc rope.

Open side at hook is provided with the open slot of walking for lock plunger.

In sum, the utility model following advantage compared to existing technology:

Charged disconnecting lead-in wire arc-extinction device and charged disconnecting lead-in wire method 1 of the present utility model, have highly versatile, improve the charged disconnecting of the making arc-extinction device that goes between and to be common to 120mm ²-400mm ²The power transmission and transforming equipment wire, have stronger versatility.

2, the convenient advantage of using, arc-extinction device main body adopt aluminium alloy make, lightweight, be convenient to the high-altitude and carry installation.The extinguishing arc coaster of improve making, but will regulate, the unified integrated once mounting of all parts such as locking puts in place, simple, convenient fast.

3, through-current capability is strong, has reduced the possibility of extinguishing arc rope heating fusing, and wire clamp can firmly be locked extinguishing arc rope and drainage thread, has eliminated the possibility that drainage thread comes off, and security reliability is high.
