AI Technical Summary

Technical Problem

Existing technologies cannot provide reliable anchor points for high-altitude operations in GIS indoor environments, and it is difficult to distinguish between work areas and non-work areas, resulting in high-risk high-altitude operations.

Method used

Flexible steel wire ropes are used in conjunction with wire locking devices to form a rope loop structure that surrounds the indoor beams of the GIS. Boundary warning components and alarms are installed on the steel wire ropes. The alarms issue warning signals when the area approaches a non-working area, thus delineating the working area from the non-working area.

Benefits of technology

It enables safe high-altitude operations within GIS indoor environments, avoids damage to the main structure, provides a rapid deployment and low-cost solution, and improves the safety and clarity of work area distinctions.

Abstract

The invention relates to the technical field of electrical detection equipment, and particularly discloses a non-intrusive horizontal lifeline device and method for high-place operation in a GIS room. The non-intrusive horizontal lifeline device comprises a steel wire rope, at least two boundary early warning assemblies, a safety belt and an alarm; the two boundary early warning assemblies are detachably installed on the steel wire rope at intervals so that the part, between the two boundary early warning assemblies, of the steel wire rope can be divided into a working interval, and the part, except the two boundary early warning assemblies, of the steel wire rope can be divided into a non-working interval. The safety belt is provided with a first hooking end used for being hooked to the working area of the steel wire rope. The alarm is arranged at the first hanging end of the safety belt and used for sending out a warning signal when the first hanging end makes contact with any boundary early warning assembly or the distance between the first hanging end and any boundary early warning assembly is smaller than a preset distance threshold value. The method has the characteristics that the GIS room does not need to be damaged, and the safety is good.
