Device.
Background technology
Aerial earth wire is the device that overhead transmission line is protected to exempt from lightning attack.In order to improve the safety of circuit operation
Property, aerial earth wire is typically all to be erected above protected conducting wire.When there is thundercloud to ground discharge in side on the line, lightning
Passage easily hits aerial earth wire first, lightning current is made to enter the earth, to protect the normal power transmission of conducting wire.Meanwhile aerial earth wire is also
There is electromagnetic shielding action, when thundercloud is to ground discharge near circuit, it is excessively electric that the caused lightning induction on conducting wire can be reduced
Pressure.Therefore aerial earth wire must securely be connected with tower grounding device, to ensure reliably lead lightning current after being struck by lightning
Enter the earth.Important transmission line of electricity generally uses two aerial earth wires that protected conducting wire is all placed in its protection domain
It is interior.
Function of the aerial earth wire due to not bearing conveying electric current, so mostly being formed using steel strand wires.Also some transmission lines of electricity
Use good conductor ground wire, the i.e. aerial earth wire made of aluminium alloy or aluminium Baogang conducting wire.This ground wire electric conductivity is preferable, can be with
Improve multi-line power transmission performance, mitigate the interference to adjacent communication line.
Power transmission line overhead ground wire defect happens occasionally, when stranded needing replacing or inspecting periodically ground occur in aerial earth wire
During line wire clamp, construction personnel needs to lift by crane aerial earth wire, unclamps ground wire wire clamp, is replaced or Inspection.Due to shaft tower knot
