The Operating Principle and Experiment of the Device for Abandoning Lines to Protect Electric Poles

Abstract

At first, it introduced the device used for abandoning lines to protect electric poles from overload in distribution lines. The device set the weak parts in the annular ring, after the deformation of the rings caused by the load, the weak parts moved first, so that the device separated into two parts, finally the electric lines would fall down from the poles. It analyzed the action theory and set up the equivalent experiment to simulate the action process. By the experiment, it shown the reliability of the device in working, and by changing sizes of the annular ring, different action force of the device would be get, so that it could use to protect various levels electric poles.
