The invention discloses a protection system for monitoring cable external force damage, which comprises a cable buried underground and a plurality of monitoring devices distributed on the cable at intervals, the cable distance from the current monitoring device to the previous monitoring device is set according to the voltage grade and the current geographic position of the cable, and each monitoring device comprises a detection alarm module, a control module and a power supply module, comprising a stress sensor, a high-frequency electromagnetic ranging unit and a judgment unit, the judgment unit is configured to wake up the stress sensor according to a set time length, obtain the stress collected by the stress sensor, determine whether to wake up the high-frequency electromagnetic wave distance measurement unit or not according to the obtained stress, and obtain a receiving time length collected by the high-frequency electromagnetic wave distance measurement unit after wake-up; and judging whether the current monitoring equipment has a hidden danger of external damage according to the obtained receiving duration, and reporting the hidden danger when determining that the hidden danger exists. The problem that due to the fact that underground cable wiring is complex, a construction unit is prone to causing external force damage to the cable is solved.
Description
technical field [0001] The present application relates to the technical field of cable fault detection, and in particular, to a protection system for monitoring the damage of cables by external force. Background technique [0002] As an important carrier for transmitting electrical / magnetic energy and information, wire and cable play a key role in the fields of industry, life and national defense. In today's highly electrified world, if the cable fails and cannot be quickly located and repaired, it will cause huge losses to social wealth, and it will also add a lot of inconvenience to people's lives. [0003] During underground construction, underground cables are easily cut off accidentally, which not only damages power equipment but also leads to regional power supply terminals. It can be seen that external force damage is one of the important factors that endanger the safety of cables. In fact, the usual practice is to ask a special geophysical exploration company to co...
