Description
Technical field
The present invention relates to overhead line construction technical field, particularly relate to a kind of overhead transmission line sag observation bar and observation thereof
Method.
Background technology
In the extension of rural power grids, transformation process, need to set up the overhead transmission line that quantity is a lot, due to wire own wt and line
There is span between the support shaft tower on road, cause two bases to support in a span in shaft tower, wire minimum point and wire two hang
Having difference in height between hanging point line, vertical distance referred to as wire is at the sag of this point.Sag is too small, and the stress of conductor can be caused excessive
Exceed wire permissible value, cause broken string；Sag is excessive, causes wire over the ground, thing safe distance is not enough to crossing over, and wind cycloid is made
Become phase fault between adjacent wires, destroy the tower structure setting up wire.The size of sag and the model of wire, weight, should
