Self-adaptive cable core line isolation tool

Abstract

The invention discloses a self-adaptive cable core line isolation tool. The self-adaptive cable core line isolation tool comprises a hollow cylinder and a handheld part, wherein one end of the hollow cylinder is a blind end, a horn opening end is formed at the other end of the hollow cylinder, the handheld part is connected with the blind end of the hollow cylinder, a plug-in hole is formed in a hollow part of the hollow cylinder and is used for being adaptive to a cable core line, the hollow cylinder and the handheld part are integrally formed by employing a silica gel material, the aperture of the plug-in hole is 2.4-2.6 millimeters, and an opening oblique angle of the horn opening end is 26-27 degrees by reference to a central axis of the hollow cylinder. The self-adaptive cable core line isolation tool has the advantages that the core line and the plug-in hole are enabled to be in effective contact and absorption and cannot fall off, the longitudinal stress on the hollow cylinder during the insertion process of the core line is optimized, the self-adaptive cable core line isolation tool has wide universality and adaptivity and is high in site practicability, a specification matching program in a traditional end package process is simplified, and the site working efficiency is improved.

Description

technical field [0001] The invention relates to an adaptive cable core wire isolation tool. Background technique [0002] With the development of social economy, the demand for electric energy shows a trend of rapid growth, and the number of power outage inspections at various levels in substations is increasing. For the power failure inspection of the power system, the safety measures of the secondary system are particularly critical. It plays a role in isolating the secondary circuit between the operating equipment and the maintenance equipment, and ensures the safe operation of the operating equipment during maintenance. [0003] The safety measures for the secondary circuit need to remove a large number of secondary circuit core wires between the operating device and the maintenance device. For a long time, the maintenance personnel of the power system have used red insulating tape to cover the exposed core wires after removing the secondary circuit core wires. The thre...

AI Technical Summary

Problems solved by technology

[0004] 1. The process of wrapping is cumbersome and time-consuming. For each core wire to be wrapped, it is necessary to manually tear off a section of insulating tape and wrap it, which leads to long isolation time and low efficiency for safety measures

[0005] 2. This treatment method has irregular and imprecise wrapping, and the exposed and unwrapped core wires touch each other, which poses a threat to the safety of the circuit

[0006] 3. The core wire of the cable carries voltage, which may cause the danger of personal electric shock in this wrapping condition

[0007] 4. After the safety measures are restored, there will be sticky colloids of insulating tape remaining on the core wires of the recovered secondary cables. The core wire of the secondary cable forms a "virtual connection"
