Abstract

The invention discloses an intermediate joint system and a partial discharge monitoring method. The intermediate joint system comprises an intermediate joint, wherein the intermediate joint comprisesan explosion-proof box, and the intermediate joint system further comprises a plurality of wireless sensors; the plurality of wireless sensors comprise at least one partial discharge wireless sensor;and the partial discharge wireless sensor is arranged in the explosion-proof box. The intermediate joint system can be used for reliably monitoring the partial discharge condition of the intermediatejoint for a long time so as to improve the use safety of the intermediate joint.

Description

technical field [0001] The invention relates to the field of electric power monitoring, in particular to an intermediate joint system and a partial discharge monitoring method. Background technique [0002] The intermediate head generally refers to the cable intermediate joint, that is, the cable joint in the middle of the cable line. The intermediate head is a cable accessory used for the intermediate connection of cross-linked cables or oil-immersed cables of various voltage levels. Its main function is to make the line smooth, keep the cable sealed, and ensure the insulation level of the cable joint to make it safe and reliable. to run. [0003] Partial discharge phenomenon is an unfavorable phenomenon mainly aimed at high-voltage electrical equipment. According to power grid statistics, partial discharge is an important reason for the final insulation breakdown of high-voltage electrical equipment, and it is also an important sign of insulation degradation. [0004] Sp...
