Problems solved by technology
Breaking the lead wire of the branch line with power is a common live work project. The operation standard requires that the branch line lead wire be broken at the vertical position. , the cutting edge of the existing insulating wire cutting shears is in a parallel state with the lead wire, making it difficult to complete the breaking work
If the angle of the insulation disconnection shear is adjusted, the insulation part of the disconnection shear may be short-circuited, which seriously affects the operation safety.
[0003] At present, there are great limitations in using the existing live working tools to carry out the ground potential work method to disconnect the lead wires of the branch lines. lead wire ends are too long, which poses a serious safety hazard

The invention relates to a disconnecting cutter head, is widely applied to online branch line lead disconnecting of an overhead distribution line, on-load isolation switch replacement and other work,and belongs to the technical field of distribution line operation sites. The cutter head is mounted at one end of a supporting rod and is perpendicular to the supporting rod; a transmission rod used for remotely driving the cutter head to work is installed on the supporting rod; the cutter head comprises a cutter holder and a fixed cutter fixed at one end of the cutter holder and a movable cuttermatched with the fixed cutter for use is arranged on the shear holder; the movable cutter is connected with a lead screw, and a ratchet transmission mechanism for driving the lead screw to ascend anddescend is mounted on the lead screw and is connected and driven by a transmission rod. The cutter head is simple in structure, convenient to use, safe, reliable, wide in application range and high inoperation efficiency.
Description
technical field [0001] The invention relates to a wire-breaking cutter head, which is widely used in work such as disconnecting lead wires of branch lines with electricity on overhead power distribution lines, replacing isolating switches with load, etc., and belongs to the technical field of power distribution line work sites. Background technique [0002] Live work is an important means for the power system to carry out grid maintenance operations and eliminate grid defects. It can complete line maintenance work on the premise of ensuring safe operation of the grid and uninterrupted power supply for users, which has great economic and social benefits. Breaking the lead wire of the branch line with power is a common live work project. The operation standard requires that the branch line lead wire be broken at the vertical position. , the cutting edge of the existing insulating wire breaking shears is in a parallel state with the lead wire, so it is difficult to complete the...
