Description
Technical Field
The invention relates to the technical field of power transmission lines, in particular to a device for removing obstacles of a power transmission line.
Background
The transmission line is realized by using a transformer to boost the electric energy generated by the generator and then connecting the electric energy to the transmission line through control equipment such as a breaker and the like. The structure form, transmission line divide into overhead transmission line and cable run.
The overhead transmission line consists of a line tower, a lead, an insulator, a line hardware fitting, a stay wire, a tower foundation, a grounding device and the like and is erected on the ground. Power transmission is classified into ac power transmission and dc power transmission according to the nature of the transmitted current. Dc transmission was first successfully achieved in the 80's of the 19 th century. However, the voltage of the dc transmission is difficult to increase continuously under the current technical conditions, so that the transmission capacity and the efficiency are limited.
