High-voltage cable fixed construction point multifunctional anti-external damage monitoring system and method

Abstract

The invention discloses a multi-functional external force damage monitoring system and method for a fixed construction point of a high-voltage cable, which realizes real-time monitoring of the grounding current of the metal sheath of the high-voltage cable, the temperature of the cable joint of the high-voltage cable, and whether the grounding wire of the high-voltage cable is stolen. The system includes a master station, a transmission device, and several terminal monitoring devices; the terminal monitoring device includes a high-voltage cable metal sheath grounding current monitoring device for monitoring high-voltage cable metal sheath grounding current data, and a high-voltage cable cable connector for monitoring A high-voltage cable joint temperature monitoring device for temperature and a high-voltage cable grounding wire anti-theft cutting monitoring device for monitoring whether the high-voltage cable grounding wire is stolen; The joint temperature and high-voltage cable grounding wire status data are uploaded to the master station after being summarized.

Description

technical field [0001] The present disclosure relates to the technical field of cable partial discharge monitoring, in particular to a multi-functional external force damage monitoring system and method for fixed construction points of high-voltage cables. Background technique [0002] High-voltage cable is a kind of power cable, which refers to the power cable used to transmit between 1kv-1000kv, and is mostly used in power transmission and distribution. Due to factors such as the weak protection awareness of power facilities in some construction units, the hidden danger of external damage has always threatened the safe operation of cable lines. [0003] The main causes of external force damage to high-voltage cables are: (1) the impact of human factors such as urban construction on the safe operation of power cables; The operation management does not pay enough attention, and the inspections of the operation personnel are not in place, and the phenomenon of omission is re...

Problems solved by technology

[0003] The main causes of external force damage to high-voltage cables are: (1) the impact of human factors such as urban construction on the safe operation of power cables; Insufficient attention is paid to operation management, and inspections by operating personnel are not in place, and omissions are common

[0004] The inventor discovered during the research and development process that the existing high-voltage cable damage monitoring methods include: manual inspection, distribution of promotional materials, and signing of safety disclosure agreements, etc., and inspection personnel need to complete regular inspections and elimination tasks every month, and it is impossible to fix the spot around the clock It is also difficult to report the hidden dangers of external damage in time to monitor the hidden dangers of construction, and the expected results cannot be achieved, and the safe and stable operation of high-voltage cables cannot be guaranteed.
