The invention discloses a non-commissioned cable anti-theft and anti-cutting alarm based on a magnetic trip principle. The alarm is installed in a cable trench, and a cable is fixed on a cable support. The alarm comprises a magnetic snap switch and an alarm box; the magnetic snap switch comprises a switch part and a magnet part, the switch part is formed by connecting, shaping and packaging a magnetic reed switch through a lead, the magnet part is formed by packaging a magnet in a plastic or alloy shell, the magnet part is fixed with a cable, the switch part is fixed on the cable support, and when the magnet part is far away from the switch part, the switch part is triggered to send out an alarm signal; and the alarm box comprises a box body and a circuit board arranged in the box body, a lead of the switch part is connected with the circuit board, a battery and a wireless communication module are installed on the circuit board, and an alarm notice is sent to a set terminal through the wireless communication module after the switch part sends an alarm signal. By adopting the technical scheme, when a lawbreaker steals and cuts a cable, an alarm can be provided in time.
Description
【Technical field】 [0001] The invention relates to the technical field of power transmission, in particular to the cable anti-theft cutting technology. 【Background technique】 [0002] The unused cables in the cable trench are relatively hidden, inaccessible, dimly lit, there is no locking device in the cable well, and there is no available 220V AC power supply. Each cable is generally within 500 meters, and the length of defense required is large, especially at night. Criminals who steal and cut are often difficult to track down afterwards. 【Content of invention】 [0003] In order to overcome the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an anti-theft and cutting alarm for unused cables based on the principle of magnetic tripping, which can provide an alarm in time when criminals steal and cut cables. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following t...
