Description
Technical field
The present invention relates to electric power operation equipment technical field, particularly relate to a kind of insulating hanging being exclusively used in equipotential live line work
Ladder.
Background technology
According to the principles of electric and electronic engineering, isoelectric level i.e. equipotential, if there is no potential difference with 2 in an alive circuit, then this
Point-to-point transmission does not has electric current, and this electromotive force of 2 is equal.Equipotential live line work in electric power operation utilizes this principle exactly, makes operation
The current potential at each position of personnel is the most equal with the current potential of band point wire, the most there is not potential difference, does not has in operation process
Electric current flows through operating personnel, thus ensures the personal safety of operating personnel.
At present, operating personnel's employing is swung when carrying out equipotential live line work into method entrance live wire, typically takes insulation
" scholar " font hanging ladder turnover isoelectric level live wire, the simple in construction of this kind of hanging ladder, but have following defects that in use
1, being limited by hanging ladder " scholar " character form structure, operating personnel needs higher control skill when taking hanging ladder turnover,
Otherwise operating personnel is difficult to bring himself into poised state in operation process, affects normal operation, and the hanging ladder of this kind of structure
It is only applicable to the operating personnel that body type is more modest；
2, this kind of hanging ladder is when extra high voltage line operation, owing to the tower head size of extra high voltage line is relatively big, and potential transfer
Process is the longest, and the time that operating personnel takes hanging ladder is long, and therefore, operating personnel needs the time controlling balance long, disappears
Expend bodily strength big, and safety is relatively low；
When 3, extra high voltage line being carried out equipotential live line work, operating personnel needs to carry with electric potential transferring stick, due to
Without auxiliary hanging point on " scholar " font hanging ladder, electric potential transferring stick cannot hang up on hanging ladder, and operating personnel needs the most hand-held current potential to turn
Move rod, so increase operation easier；
4, " scholar " font hanging ladder uses single suspension centre structure, operating personnel take can produce during hanging ladder swings spin existing
As, and the uncontrollable rotation direction of operating personnel, it is unfavorable for operation.
Summary of the invention
