Abstract

The invention discloses a novel on-line monitoring device for a high-voltage cable connector. The novel on-line monitoring device comprises a connector box, a screening tube is installed inside the connector box, and a passive wireless measurement sensor is embedded into the screening tube; the external portion of the connector box is connected with a transmission signal optical cable through a wireless receiver. The novel on-line monitoring device for the high-voltage cable connector can measure the heat and noise changes of a stress cone portion within the closest distance and transmit the changes to the wireless receiver on a shell of the connector through wireless signals and then transmits the changes to a measurement instrument through an optical cable. Compared with other measurement means, the novel on-line monitoring device has excellent sensitivity, accuracy, reliability and anti-interference, and the on-line monitoring device for the cable solves the problem that on-line monitoring can not be performed accurately.
