Abstract

The invention belongs to the technical field of electrified operation devices of high-voltage transmission lines, and particularly relates to a strong electric field access device. The strong electricfield access device comprises a traction system, an operation system and a protection system, wherein the traction system comprises a traction machine, a follower pulley and a lifting rope; the operation system comprises a three-dimensional framework I and a plane framework II, and the framework II is arranged at the upper end of the rear side of the framework I; a pedal I is arranged on the lower side of the framework I, and a connecting part I is arranged on the framework I; a pedal II is arranged on the left side and the right side of the framework I in a foldable mode; a plane framework III is arranged on the left side and the right side of the upper end of the framework I in a foldable mode; the upper end of the framework III is detachably connected with the framework II through a buckle; the lifting rope is connected with the traction machine, the follower pulley and the connecting part I in sequence; and a protection rope is connected with the connecting part I and a locking pulley. By virtue of the strong electric field access device, the labor intensity of operators can be reduced, the operation area can be expanded, and the operation can be facilitated, and meanwhile, the safety of the operating personnel is guaranteed, and the strong electric field access device is convenient to store in a warehouse, and is convenient to store and transport on roads.

Description

technical field [0001] The invention belongs to the technical field of live working devices for high-voltage transmission lines, and in particular relates to a device for entering and exiting a strong electric field. Background technique [0002] In the live maintenance operation of 110-220kV transmission lines, the equipotential operation method is one of the commonly used operation methods. Equipotential work refers to the work performed when the operator wears a full set of shielding protective equipment and enters a strong electric field with the help of insulating tools such as an insulating ladder, and the operator directly contacts the charged body and is at the same potential as the charged body. Live repairing of wires, live replacement of shock-proof hammers, live replacement of the entire string of insulators and other live maintenance operations of transmission lines often need to be carried out by means of equipotential work, and equipotential personnel need to ...

AI Technical Summary

Problems solved by technology

[0004] The use of the above-mentioned strong electric field device will have the following problems: 1. When the wires that need live maintenance are too high, the equipotential personnel rely on manpower to climb the soft ladder to enter and exit the strong electric field, and the physical exertion is too large, which is easy to cause the physical condition when working in the strong electric field In the case of poor mental state, it is impossible to carry out work efficiently and attentively, thereby reducing work efficiency and work quality, and increasing safety risks; 2. Due to the limitation of the structure of the insulated ladder, the working area for equipotential personnel carrying out equipotential maintenance work at high altitude It is narrow and inconvenient to carry out actual work; 3. Equal potential personnel working at heights may lose backup protection due to human factors of ground electricians, resulting in high-altitude falling accidents, and the protection measures are not safe and reliable enough
