Abstract

A power equipment power failure alarm device comprises an inverter, a modulating oscillator, an alarm module and a power module, wherein the power supply of a power distribution facility is connected with the inverter, the output end of the inverter is connected with the modulating oscillator, the modulating oscillator is connected with the alarm module and the power module provides power sources for the inverter and the modulating oscillator. The invention aims at that the city dwellers have had single phase alternating 220V household electrical appliances, the stealing of the power distribution facility needs to cut electricity off and then the terminal power sources of residential customers are cut off, so that the voltage of the terminal power sources of residential customers is detected, the inversion signal is collected to trigger the alarm device to work, the residential customers who are asleep can be alarmed, and the preliminary sign detection and early warning for the stealing of the power distribution facility can be realized. The invention has simple structure, is easy to realize and can be widely used for the anti-theft alarm of various power distribution facilities.

Description

technical field [0001] The invention relates to an on-line detection device for anti-theft of electric power facilities. The device can quickly send out sound and light reminders when a power failure occurs at a power receiving terminal of a resident customer, and is a power failure alarm for electric equipment. Background technique [0002] During the operation of power facilities, criminals will encounter theft, such as the common theft of distribution transformers, low-voltage household wires, and so on. Thieves often commit crimes late at night, when everyone is resting and it is difficult to find them, let alone drive them away. If there is a method that can detect the early signs of the theft of power distribution facilities, and remind the sleeping people, it will be possible to jointly drive away or call the police to arrest, protect the power facilities from being stolen, and ensure the normal use of electricity by customers. This was researched and developed. Co...
