Abstract

The invention discloses an angle sensor provided with temperature compensation fibers and used for measuring a level angle of a pole tower. The angle sensor comprises a sensor packaging casing, a base plate, a platy swing arm, a swing hammer, a first jackscrew and a second jackscrew, wherein the base plate is fixedly connected to the top of the sensor packaging casing; one end of the platy swing arm is fixed on the base plate; the swing hammer is fixed at the other end of the platy swing arm; the first jackscrew is arranged on the left side of the sensor packaging casing and corresponds to one end of the swing hammer; the second jackscrew is arranged on the right side of the sensor packaging casing and corresponds to the other end of the swing hammer; strain detection optical fiber Bragg gratings are attached in the length direction of the platy swing arm; and environment temperature detection optical fiber Bragg gratings are in series connection with the strain detection optical fiber Bragg gratings. According to the angle sensor, high-precision level angle measurement of the pole tower can be realized and is not affected by an electric field or the environment temperature.

Description

technical field [0001] The invention relates to the technical field of optical fiber angle sensors, in particular to an optical fiber angle sensor with temperature compensation for measuring the horizontal angle of a tower. technical background [0002] The horizontal angle of the tower of the high-voltage transmission line is an important index reflecting the operation status of the tower. Due to the influence of icing, conductor galloping, etc., the collapse accidents of high-voltage transmission line towers occur from time to time. The measurement of the horizontal angle of the tower plays an important role in monitoring the health status of the tower. Therefore, the power sector requires regular monitoring of the horizontal angle of the tower. Conventional high-voltage transmission line tower horizontal angle monitoring uses electrical angle sensors, or testers use special equipment to measure and record the horizontal angle of the tower under the tower, and then analyz...
