Description
Technical field
The present invention relates to a kind of 35kV voltage class routes to charge the method for connecing unloaded lead, belongs to transmission of electricity livewire work skill
Art field.
Background technique
Currently, electric transmission line hot-line connects unloaded lead, frequently with the method that extinguishing arc rope connects unloaded lead, since this method needs
Biggish electric clearance distance is wanted, using more in 110kV and Above Transmission Lines.
20kV and distribution circuit electric voltage grade below are lower, and electrification connects unloaded lead frequently with insulating glove working system.
The operational method needs operating personnel to wear the insulating protection apparatus of relevant voltage grade, in insulation carrying platform (such as insulation bucket arm
Vehicle) on perfect insulation masking is carried out to electrical body and grounding body after, then carry out connecing unloaded lead operation.Insulation clothing etc. is exhausted at present
Edge safety device is generally used for 20kV and following voltage class route.
35kV voltage class transmission line of electricity often undertakes important role in counties and districts power.With economic development,
The case where T link, is more and more in 35kV voltage class.The voltage class route has the higher voltage of transmission line of electricity simultaneously
The features such as grade and distribution line Insulation Coordination are low, electric clearance is small, personnel activity's range is smaller, conventional transmission of electricity electrification, which connects, draws
The method that method (such as extinguishing arc rope method) and the distribution electrification of line connect lead (such as insulating glove working system) is difficult to meet the voltage
