The invention relates to a current leading-out device of a resting cable, an installation method and an anti-theft alarm system, the current leading-out device is used for detecting a current signal of a tested resting cable, the current leading-out device is used for connecting a cable head of the tested resting cable, the current leading-out device comprises a sealing cap, a sealing cap connector, a conductive pile and a wire, and the cable head comprises a sealing cap part and an outer protection part. An outer protective layer of the tested resting cable is removed from the cap sealing part; the sealing cap is of a cylinder structure, a containing chamber matched with the sealing cap part in size and used for containing the sealing cap part are formed in the sealing cap, the conductivepile is located in the containing chamber and used for being connected with a wire core and being connected out through a wire, a wiring hole is formed in the bottom of the sealing cap, and the sealing cap connector is fixedly connected with the sealing cap and provided with a wiring end; and a wire is connected to the wiring end through the wiring hole. Compared with the prior art, through the multi-layer waterproof design, the sealing of the conductive pile is achieved, the waterproof effect is achieved, the circulation signals can be stably collected, and the reliability of cable anti-theft monitoring is guaranteed.
Description
technical field [0001] The invention relates to the field of cable anti-theft, in particular to a current lead-out device for a dormant cable, an installation method and an anti-theft alarm system. Background technique [0002] Extra-high voltage dormant cables refer to power cables with a voltage level of 110kV and above that have been out of service for a long time but will be partially utilized or fully utilized in a certain period of time in the future. Since such cables have been out of service for a long time, once they are stolen, it is difficult to find them in a short time. Like ordinary cables, the core (601) of the EHV resting cable is mainly made of metallic copper. Due to the rising copper price and the copper content of the EHV resting cable is more, incidents of theft against it are increasing. The theft of extra-high voltage resting cables will not only cause direct economic losses to power companies, but also cause delays in some construction projects, resu...
