The invention relates to the field of sensors, in particular to an optical fiber angle transducer for measuring a windage yaw angle of an insulator. The optical fiber angle transducer comprises a housing (6), pendulum bobs (1), swinging arms (2), optical fiber rasters (3) and a substrate (4 ), wherein the substrate (4) is fixed in the top of the housing (6); the upper ends of the swinging arms (2) are connected to the substrate (4 ), and the lower ends are connected to the pendulum bobs (1); the optical fiber rasters (3) are integrally fixed on the swinging arms (2); hold hoops (5) are fixed on the side wall of the housing (6), and fittings clamped at the low voltage end of the insulator, of the hold hoops (5) enable the optical fiber rasters (3) inside the hold hoops (5) to be vertical downwardly. The optical fiber angle transducer provided by the invention is free from electromagnetic interference, does not need power supply, is high in measuring accuracy and resolution, is high in respond speed, and can be used in the harsh environment with high temperature, high humidity, chemical erosion and the like.

Description

technical field [0001] The invention relates to the field of sensors, in particular to an optical fiber angle sensor used for measuring the wind angle of an insulator. Background technique [0002] The wind deflection angle of the insulator of the high-voltage conductor is an important indicator to reflect the operation status of the line. The angle of the insulator plays an important role in monitoring the galloping of the conductor. Therefore, it is required to monitor the angle of the insulator regularly. In the past, electrical angle sensors were used, or testers went down the tower to use special equipment to measure, record, and then analyze the angle of the insulator. However, these two measurement methods often have disadvantages such as being affected by the high-voltage electric field environment, poor accuracy, affected by climate, wasting manpower, and unable to detect problems in real time. Therefore, how to accurately reflect the angle of the insulator in real...
