Problems solved by technology

However, the above methods have obvious limitations: the leakage current detection method can only reflect the results after the transmission line is damaged, and it cannot work when the power is off; the power line carrier detection method faces high noise, large impedance changes, and signal transmission during the monitoring process. Large loss and other problems; point strain sensors can not locate the fault point and can only be arranged in some special positions on the transmission line, the monitoring range is not comprehensive enough, on the other hand, there is a certain deviation between the strain detection value and the actual value, which cannot fully reflect the real situation

Embodiment 1

[0025] This embodiment provides a holographic sensing external force damage monitoring system to monitor the external force damage of cables, such as figure 1 As shown, part A in the figure represents the above-ground part, and part B represents the underground part. The cable 1 is connected from the power plant 2 and connected from the underground to the power terminal 3 by means of buried pipes, cable trenches or cable tunnels. The holographic perception external force damage monitoring system includes a sensor module, a host 5 and a monitoring terminal 6. The host 5 is placed in the monitoring room at one end of the cable line or in the ground monitoring terminal to run calculations and monitoring processes and provide monitoring alarm data. The monitoring terminal 6 can be Computers and / or mobile phones are not limited here. In this embodiment, the holographic sensing external force damage monitoring system further includes a camera 8 which is controlled by the host 5 and ...

Abstract

The invention discloses a holographic external force damage sensing monitoring system, and relates to the technical field of power transmission. The technical scheme provided by the invention is usedfor monitoring external force damage of the cable, the system comprises a sensing module, a host and a monitoring terminal, the sensing module picks up a vibration signal of a cable channel and transmits the vibration signal to the host, and the host comprises a database, analyzes signal characteristics, compares the signal characteristics with signal characteristics in the database and sends alarm information to the monitoring terminal according to a comparison result. According to the technical scheme provided by the invention, the safety problem of an existing power cable is solved throughreal-time online monitoring.

Description

【Technical Field】 [0001] The invention relates to the technical field of power transmission, in particular to a holographic sensing external force damage monitoring system. 【Background technique】 [0002] With the increase of electricity load, the grid power supply system gradually develops to the ring-type power supply mode. In order to enhance the reliability and safety of power supply, most of the urban power grid systems adopt the method of tunneling underground, cable trench or cable tunnel. Because of its high copper content, scattered distribution, and unattended characteristics, cables have gradually attracted the attention of thieves, causing great social risks; on the other hand, cables are widely distributed due to their own laying characteristics, and monitoring is inconvenient There are more and more risk points of damage caused by external forces. Especially with the progress of my country’s urbanization process and urban optimization and transformation and upgradin...
