Abstract

The invention discloses an optical fiber MEMS sensor used for a cable joint, which includes a sensing component and a fastening component, the fastening component includes a ring-shaped fastening strip, an installation hole is arranged in the middle of the ring-shaped fastening strip, and the sensor The assembly is installed in the installation hole; the locking assembly includes a locking piece, the locking piece is provided with a through hole, and the two ends of the annular fastening strip pass through the through hole; The fixing of the sensor can ensure that the probe of the sensor sticks to the surface of the cable joint.

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...
