Abstract

The invention relates to a power transmission wire sag adjusting device which comprises a wire feeder. The wire feeder comprises a wire feeder support connected with a corresponding iron tower through a connecting piece in use, and an upper side rolling body and a lower side rolling body are arranged on the wire feeder support. The upper side rolling body and the lower side rolling body are used for being matched with corresponding guide friction rolling so as to drag a wire to move, an inclination angle measurer used for detecting the inclination angle of the wire is arranged on the wire feeder support, and the upper side rolling body and / or the lower side rolling body are / is a driving rolling body driven by a motor power mechanism. The technical problems that in the prior art, time and labor are wasted when a paying-off pulley is manually rotated to adjust the sag, and the sag accuracy cannot be guaranteed are solved.

Description

technical field [0001] The invention relates to a power transmission wire sag adjustment device in the field of high-altitude stringing of power transmission lines. Background technique [0002] When stringing wires at high altitude, install a pay-off tackle on the iron tower, and use the pay-off tackle to carry out high-altitude payout. The sag of the wire is very important during the pay-off process. The sag of the transmission line is the main indicator of the safe operation of the line, which is related to the safety of the line. It is safe to operate, so it must be controlled within the scope specified in the design. Due to changes in line operating load and surrounding environment, changes in line sag will occur. Excessive sag will not only cause hidden dangers of accidents, but also limit the transmission capacity of the line, especially It is in the intersection and densely populated areas. [0003] In order to realize real-time monitoring of sag is the goal of dome...
