Application Research of Fiber Bragg Grating for Sensing Finger Pressure Detection on High Voltage Isolate Switch

Abstract:

The sensing finger pressure does not meet the requirements can cause isolation switch overheating, even lead to accident in the operation of high voltage isolate switch. According to the structure of isolating switch, FBG pressure sensor and FBG displacement sensor are installed on isolate switch, which constitute the sensing finger pressure detection system. The sensing finger pressure detection experiments indicate that, when the moving contact’s closing position of isolate switch changes from 0.267mm to 29.040mm, the sensing finger pressure ranges from 30.378N to 32.970N.However, when spring pressure changes from 42.776N to163.827N, the sensing finger pressure ranges from 29.033N to 111.193N.The sensing finger pressure measuring system can realize real-time and online monitoring of the sensing finger pressure.
