Description
Technical field
The present invention relates to the safeguard protection earthing or grounding means in a kind of power construction, is applied particularly to protect power construction personnel
With the safety of equipment, avoid setting up and changing electric shock accidents of causing danger in work progress in aerial condutor.
Background technology
With the fast development of China's power transmission network, electric power transmission channel environment becomes to become increasingly complex;In same transmission of electricity
In passage, the transmission line of electricity of different voltage class is laid with(Extra high voltage line, backbone network circuit, distribution line), different is defeated
Between electric channel, the circuit for the leap that intersects there are;After transmission line of electricity runs to certain time, due to many reasons(Always
Old, increase conveying load, stranded damage), replacing transformation need to be carried out to transmission pressure.In construction reformation is changed, in order to reduce
User's power failure area, it is frequently encountered following several situations:(1)The situation of " π " link is laid with single back line, as " π "
During link wire replacing, former single back line charging operation, " π " wiring line conductor must be made to keep one with alive circuit in construction
Set a distance, once there is the carelessness of non-standard operation or work, it may occur that the accident abutted against with alive circuit, cause personal electric shock
Generation.(2)In Tong Ta(Bar)On multi circuit transmission lines, if carrying out wire replacing to a wherein loop line road, and other return leads must
During palpus charging operation, the carelessness of non-standard operation or work can cause and alive circuit is abutted against, and accident of human electric shock occurs.(3)
Intersect in the circuit of leap, that restringing needs leap to have a power failure working line be present, also have circuit and touch
The problem of connecing, cause the generation of accident of human electric shock.
Live restringing work progress is as follows:Circuit power-off will be first replaced, workmen, which hangs wire guide pulley wheels, to be pacified
On cross arm of tower where wire is changed, wire will be replaced and be placed on wire guide pulley wheels, and anticreep screens.Changed
New wire paying out reel is placed on the ground of wire one end, the termination for being changed wire and new bobbin are connected to one by hauling rope
Rise;On the ground of the other end for being replaced wire, winch is placed, the other end of old wire is connected with winch.By old wire
Dismounting " loose ends " is fixedly connected with overhead line structures, wire is moved on pulley.One man operation winch carries out take-up, separately
One people carries out unwrapping wire, and new wire is drawn by old wire, by the wire guide pulley wheels in more base shaft towers, enters the winch of the other end
On, so as to complete the replacing of wire.During whole replacing construction, if safety measure is not in place or due to weather, construction
Many-sided reason such as terrain environment, height can be caused to be replaced wire in the air and abutted against with live wire, the point that gets an electric shock can pass through receipts
Line side and unwrapping wire side joint, form two discharge paths, cause casualties and device damage.
