Description

Technical Field

[0001] The utility model relates to the technical field of monitoring and early warning, in particular to a cable online monitoring and fault early warning distance measurement system. Background Art

[0002] The power cable online monitoring and fault warning ranging system is widely used in the current cable monitoring. The power cable online monitoring and fault warning ranging system can play the role of cable fault warning and precise positioning. The online monitoring system includes: cable fault warning, cable partial discharge positioning, temperature status monitoring, and operating load monitoring; it is mainly used for 10kV-220kV cable online monitoring.

[0003] However, the current monitoring points in the online monitoring and fault warning ranging system of power cables are difficult to deploy, and the number of monitoring points that can be deployed is limited; when a fault occurs, it is necessary to continuously excavate the ground and connect the detection device to the cable, so as to continuously reduce the length of the cable fault position. The whole operation is very cumbersome and it takes a long time to determine the fault point. For this reason, we provide a power cable online monitoring and fault warning device (see patent number: 202120730707.3 for details), including a pre-buried pipe, a transfer conductive component is installed at the bottom of the pre-buried pipe, and a detector for detecting the current of the transfer conductive component is detachably installed inside the pre-buried pipe; The bottom end of the embedded pipe is installed with a first external component and a second external component which are arranged in a mirror-symmetrical manner. The first external component is sleeved on the end of the first cable, and the second external component is sleeved on the end of the second cable. The transfer conductive component has two detection ends, one detection end is electrically inserted into the first external component, and the other detection end is electrically inserted into the second external component. The utility model can facilitate the fixing of the embedded pipe underground through the two preset external components, and the detector can be directly installed in the embedded pipe to realize real-time monitoring. For the embedded pipe without the detector installed, the detector can be directly inserted into the embedded pipe, which is simple and quick to operate.

[0004] However, the existing cable online monitoring and fault warning ranging system has troublesome connection work, which greatly increases the workload. At the same time, the connection is also relatively loose, resulting in the cable and the device being separated. At the same time, when the cable is interrupted, only detection can be performed, and no signal can be generated to remind maintenance personnel to carry out maintenance. Moreover, after the cable is restored, it cannot be reset by itself, and the device can only be reset manually, which greatly increases the workload. Utility Model Content

[0005] The purpose of the utility model is to solve the problems of the existing cable online monitoring and fault warning ranging system, in which the connection work is troublesome, which greatly increases the workload, and the connection is also relatively loose, resulting in the separation of the cable and the device.
