Abstract

The invention discloses a fault early warning sensor for a high-voltage cable connector, and the early warning sensor comprises a sensor and a hoop; the hoop is composed of two arc-shaped hoop sheets,and the two sides of the sensor are hinged with the two arc-shaped hoop sheets through hinges; the sensor comprises a shell, a communication interface, a circuit board and a probe, wherein the communication interface is arranged on the shell, the circuit board is fixed inside the shell, the communication interface and the probe are connected with the circuit board through wires, the probe is fixed below the shell, and the probe is in contact with the surface of a cable joint. The high-voltage cable joint fault early warning sensor adopting the structure is simple in structure and easy to install, and can monitor abnormal signals of a cable joint in real time and send out early warning in time.

Description

technical field [0001] The invention relates to the technical field of high voltage electricity, in particular to a high voltage cable joint fault early warning sensor. 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. Contents of...
