Abstract
A sensor system for measuring an angle of a gate of an isolating switch of overhead lines, comprising an optical fiber angle sensor, a base, a support plate, a light source fiber, a laser transmitter, an aluminum box, a relay, a step-down power module, a control circuit board, a photoelectric converter, and a receiving optical fiber. The support plate is arranged on an upper part of a pillar insulator; the optical fiber angle sensor is arranged on the base to detect a rotation angle of the gate; the laser transmitter is controlled to emit a laser beam into the light source fiber; the laser beam is received by the receiving optical fiber and transmitted to the photoelectric converter to convert a light intensity into a voltage signal; the converted voltage signal is transmitted to the control circuit board for processing, and the angle of the gate is output.
