High-voltage disconnector status recognition technology applied to optical fiber
In order to solve the problem that the opening and closing state cannot be directly obtained in the traditional high-voltage disconnector state detection method,a high-voltage disconnector angle measurement sensor applied to optical fiber is designed.The input and output characteristic curves of the sensor are fitted by the least squares method,and the curve fitting method is used for nonlinear compensation to reduce the nonlinear error of the sensor.A temperature compensation model based on binary regression analysis is established for temperature compensation.The experimental results show that the nonlinear error of the sensor is reduced from 15.7％ to 5.7％ after nonlinear compensation by using the curve fitting method.After temperature compensation,the zero temperature coefficient is reduced by nearly 3 times,the sensitivity temperature coefficient is reduced by more than 9 times,the relative error is reduced by 4.52 percentage points,and the average absolute error of the sensor is 0.49％,which meet the design needs.
