Description

technical field [0001] The invention relates to the field of sensors, in particular to an optical fiber MEMS sensor used for cable joints. Background technique [0002] With the continuous development of the power grid, the application of power cables is becoming more and more extensive, and cable detection technology has become an important topic in the power industry. The electric field stress of the intermediate joint of the power cable is relatively concentrated, which is the weak link of the power cable insulation. It is often easy to cause the cable breakdown due to the deterioration of the cable insulation performance, that is, the partial discharge problem. The partial discharge problem of high-voltage cable joints is the main factor causing high-voltage cable accidents. Doing a good job in the detection and early warning of high-voltage cable joints is the primary task to ensure the normal operation of high-voltage cables. However, in the prior art, the sensors ins...
