Anti-power-stealing alarm apparatus

Abstract

The invention relates to an electric anti-theft alarm, which comprises a rectifier, a DC power supply and a transformer. The input terminal of the rectifier is AC alternating current, the output terminal of the rectifier is connected with a DC power supply, the input terminal of the DC power supply is connected with a rectifier, and the negative pole of the output terminal of the DC power supply is connected with an alarm. Terminal A of the device, the positive pole of the output terminal of the DC power supply is connected to the terminal B of the switch and the alarm, the alarm is provided with a dialer and a door sensor, and the output terminal C of the alarm is connected in series with a resistor and a switch in sequence. There is a wire A and a transformer, and the wire A surrounds the transformer for 2 weeks; when the distribution box of the present invention is illegally opened or when the mobile transformer breaks the wire A, the alarm will sound an alarm and dial to the person in charge to notify, and the power of the alarm will The battery is used, and the battery is connected with an inverter power supply, which has the advantages of automation, high safety, complex structure, not easy to be damaged, and power failure prevention.

Description

technical field [0001] The invention belongs to the technical field of power distribution anti-theft devices, and in particular relates to an electric power anti-theft alarm. Background technique [0002] With the country's implementation of the Sannong Project, many agricultural transformers or distribution boxes have been built on farmland equipment. Due to the current large number of agricultural population entering the city to work, the labor force and labor density required for farmland are reduced, and these equipment are unmanned during the shutdown period. Nursing, easy to lose and damage, the general anti-theft measures are to use ground piles or iron chains or build power distribution rooms, but these measures are not effective, and because they cannot be monitored, the anti-theft measures are easy to be destroyed, and the loss caused by theft is huge Therefore, an anti-theft device with better anti-theft effect, automation and monitorability is needed.
