Problems solved by technology

The traditional detection method is often to connect the secondary current of the protective current transformer at the power distribution terminal, and detect the short-circuit current by judging whether the line current exceeds the preset value (set value), which is inconvenient to use
In addition, traditional detection methods are not convenient for remote monitoring

[0055] Network interface 1, current acquisition unit 2, signal amplifier 3 and analog-to-digital converter 4 are connected in sequence, analog-to-digital converter 4, input unit 5, detection start button 9, detection end button 10, first memory 11, display 6 and dat...

Embodiment 2

[0096] figure 2 It is another embodiment of the power communication network line detection system of the present invention.

[0097] Compared with Embodiment 1, this embodiment is different in that, in the power communication network line detection system in this embodiment, the processor 8 of the detection subsystem 100, after each data upload is completed by the data upload unit 7, All data stored in the first memory 11 are deleted. In order to continue to store new data in the future.

[0098] In addition, in this embodiment, the detection subsystem 100 of the power communication network line detection system further includes:

[0099] The second memory 13 is used for storing data deleted in the power communication network line detection system.

[0100] When in use, the processor 8 deletes all data stored in the first memory 11 after each data upload is completed by the data upload unit 7, and stores all data deleted from the first memory 11 to the second memory 13. ...

Embodiment 3

[0104] This embodiment is another embodiment of the power communication network line detection system of the present invention.

[0105] Compared with Embodiment 2, this embodiment is different in that, in the detection subsystem 100 of the power communication network line detection system described in this embodiment, the processor 8 is also used to convert the received modulus The data output by the converter 4 is compared with a preset reference current threshold to obtain a current detection result;

[0106] The processor 8 is further configured to display, through the display 6, prompt information corresponding to a fault in the power communication network line under test when the obtained current detection result is abnormal.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an electric power communication network line detection system. Background technique [0002] The power communication network came into being in order to ensure the safe and stable operation of the power system. Together with the relay protection, safety and stability control system and dispatching automation system of the power system, it is collectively called the three pillars of the safe and stable operation of the power system. An important means of safe, stable, and economical operation is an important infrastructure of the power system, and it has strict requirements on the reliability of communication. [0003] In order to ensure the reliability of power communication network communication, it is often necessary to detect the line current of the power communication network line. The traditional detection method is often to connect the secondary current of the protective cur...
