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

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Certain directional terms used hereinafter to describe the drawings, such as "inner," "outer," "above," "below" and other directional terms, are to be understood those directions involved in the drawing. Unless otherwise specified, the directional terms described in this specification basically follow the conventional directions understood by those skilled in the art.
[0021] The terms "first", "first", "second", "second" and similar terms used in the present invention do not indicate any order, quantity or importance in the present invention, but Used to distinguish one part from other parts.
[0022] refer to Figure 1-Figure 2 , a replacement tool 100 for live replacement of tension insulator strings, comprising: a clamp 1, including a front clamp 11, a rear clamp 12 and two clamps connected between the front clamp 11 and the rear...

The present invention provides a replacement tool for live replacement of tension insulator strings, including: a clamp, including a front clamp, a rear clamp and two extension rods connected between the front clamp and the rear clamp, The front clamp and the rear clamp are respectively detachably clamped to the front fixed end and the rear fixed end of the tension insulator string, and the front clamp is also provided with a penetrating piece; a bottle holder for bearing Support the strain insulator string, one end of the bottle holder is hinged to the rear clip, and the other end can be controlled to extend into or out of the penetrating part; when the strain insulator string is connected to the front When the fixed end is disconnected, the other end of the bottle holder protrudes from the piercing member, and the bottle holder supports the tension insulator string and can be controlled to pivot relative to the rear clip. The application of the technical scheme can realize the effect of live replacement of tension insulator strings.
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...
