Description
Technical field
The invention belongs to distribution line application tool fields, in particular to a kind of quickly to adjust conducting wire sag device.
Background technique
Arc sag refers on a flat ground, when conducting wire suspension height is identical on adjacent two bases electric pole, conducting wire minimum point and two
The vertical range of line between hitch point.Generally, when transmission distance farther out when, due to conducting wire be self-possessed, will form slight arc sag,
Making conducting wire is in the shape of catenary, if suspension point height of the conducting wire on adjacent two electric pole be not identical, at this point, in a span
Interior two arc sags will occur, i.e. the two of conducting wire hitch point to conducting wire minimum point there are two vertical range, referred to as maximum arc sag and
Minimum arc sag theoretically needs infinitely great power since a conducting wire is straightened, and such power is not present in practice, if electric
Line conductor arc sag is excessive, the safe distance that the distance between route minimum point and the earth will be made to be unsatisfactory for design requirement, and
