Description
Technical Field
The invention relates to an anti-theft device for a power cable, which is particularly used for the anti-theft of the cable of a power transmission line, in particular to the anti-theft of the power transmission cable below 35 kV.
Background
The overhead cable with the high density and the large length of 35kV or below is widely applied, still is the current mainstream cable laying mode, and occupies a large proportion in an urban power grid. For some persons who steal cables, a common stealing mode is to pull and steal the two ends of the cables after cutting the two ends, and this mode still causes the theft of our power transmission lines with the addition of auxiliary tools (for example, for a cable anti-theft device disclosed in chinese patent CN201010257195X, although the anti-theft capability is increased by steel strands, the cutting capability of new hydraulic tongs is also that the steel strands can still be easily cut after being promoted), especially for suburb power transmission lines governed by the state power supply company.
The current situation and the defects of the current aerial cable for preventing burglary are as follows:
(1) the traditional overhead cable is prevented from being stolen by depending on manual regular inspection, and because the manual inspection belongs to passive protection, the stealing behavior is difficult to find in regular inspection; meanwhile, with the increasing number of cables in recent years, the jurisdiction area is increasingly expanded, and the daily inspection workload of operators is more and more large.
(2) Some intelligent anti-theft devices are only provided with monitoring cameras at present, the monitoring cameras are used for a long time, so that the data storage and transmission pressure is high, and the cameras cannot reliably obtain evidence when the on-site image capturing evidence is really required to be called;
(3) the existing camera monitors the burglary prevention and is matched with a buzzer or a warning lamp to give an alarm, the warning effect is limited, and the further burglary behavior of a burglar and the behavior of dismantling a burglary prevention facility cannot be prevented. For example, the power cable burglar alarm device disclosed in chinese patent CN2015200996099 detects through an infrared camera, and an audible and visual alarm gives an alarm, including a data transmission monitoring center, but this process is only a warning effect, and cannot prevent the behavior of stealing and dismantling the alarm device of a thief in the next step.
