Embodiment 1

[0030] This embodiment has a cable partial discharge real-time monitoring system with route planning, including a local area network, the Internet, five partial discharge detectors, two community cable management stations, two mobile terminals and a control center;

[0031] Such as figure 1 As shown, the partial discharge detector A1, partial discharge detector B2, partial discharge detector C3, partial discharge detector D4, and partial discharge detector E5 are respectively installed on the five utility poles;

[0032] Such as figure 2 As shown, community cable management station M manages partial discharge detector A1 and partial discharge detector B2, community cable management station N manages partial discharge detector D4 and partial discharge detector E5, community cable management station M and community cable management Station N jointly manages the partial discharge detector C3 at the junction of the community;

[0033] The partial discharge detector includes a d...

Embodiment 2

[0066] This embodiment is further optimized on the basis of Embodiment 1. The partial discharge detector further includes a self-inspection module. The self-inspection module verifies the partial discharge detector, and the communication module sends the verification result to the control center.

[0067] The partial discharge detector ensures its reliable operation through self-inspection, which can effectively avoid the phenomenon of missing or wrong signals due to the failure of the partial discharge detector.

Embodiment 3

[0069] This embodiment is further optimized on the basis of Embodiment 2. The mobile terminal further includes an alarm module, and the alarm module sends out an alarm bell when the receiving module receives task assignment information.

[0070] The alarm bell can attract the attention of maintenance personnel and remind them to accept maintenance tasks in time.

Abstract

The invention provides a cable partial discharge real-time monitoring system with a line planning function. The system comprises a network, at least one partial discharge detector, a control center, at least one community cable management station and at least one mobile terminal, wherein the partial discharge detector is connected with the control center through a network, the community cable management station is connected with the control center through the network, and the mobile terminal is connected with the community cable management station through the network. The cable partial discharge real-time monitoring system can accurately position a discharge position of a cable at an operation state and measure discharge intensity, plans an optimal line for maintenance personnel, and is suitable for monitoring an overhead cable between a transformer station and a user.

Description

technical field [0001] The invention relates to the field of cables, in particular to a cable partial discharge real-time monitoring system with route planning function. Background technique [0002] During the operation of the cable, the aging of the cable insulation will lead to the occurrence of partial discharge. The change of the partial discharge indicates that there is a defect in the cable insulation that may endanger the safe operation of the cable. Safety incidents may occur. [0003] The Chinese invention patent application with the filing date of March 2, 2012 and the application number of 201210075267.8 discloses a cable partial discharge detection system, including a partial discharge tester, a photoelectric converter, a signal processor, and a display terminal. The signal processors are respectively It is connected with a photoelectric converter and a display terminal, the photoelectric converter is connected with a partial discharge tester, and the partial d...
