Description

Insulating drainage wire fixing device Technical Field The invention belongs to the technical field of live working of power distribution networks, and particularly relates to an insulating drainage wire fixing device. Background In live working of a power distribution network, replacement of equipment such as a drop-out fuse, a lightning arrester, a circuit breaker and a disconnecting switch is a routine and important maintenance project, and the like, is usually implemented by adopting an intermediate potential working method and entering a live region by means of equipment such as an insulating arm car, an insulating platform and the like. However, in the operation process, a technical problem which exists for a long time and is not properly solved seriously restricts the operation efficiency and the safety, namely when the electrified drainage wire on the equipment is released, the suspended drainage wire is in a suspended state, and under the action of wind power, slight touching of operators or self gravity of the drainage wire, the suspended drainage wire is easy to swing, so that the electric safety distance between the suspended drainage wire and an adjacent grounding body (such as a cross arm and a pole tower) or other adjacent electrified bodies is greatly reduced, even the electric safety distance is directly contacted, single-phase grounding or inter-phase short-circuit accidents are caused, and the safety of the operators and the equipment is seriously threatened. Because of lack of a safe, reliable and convenient temporary fixing means for the drainage wire, in order to ensure a safe distance, sometimes the power outage range has to be enlarged or more complex insulating shielding measures are adopted, which results in complicated operation flow and low economy and efficiency. In addition, the existing tools or methods for temporarily fixing drainage lines are designed for specific scenes, for example, a simple single drainage line fixing frame cannot cope with maintenance tasks of simultaneously releasing a plurality of drainage lines, and in order to fix a plurality of drainage lines, a plurality of independent tools can be carried and operated on site, so that the problems of complicated installation, mutual interference, occupation of precious operation space and the like exist. For different operation demands of single-phase, two-phase and three-phase equipment and the like, namely, for different drainage wire number scenes (such as single drainage wire, two drainage wires and three drainage wires), a unified solution capable of being rapidly and flexibly adapted is lacking at present.
