Variable-frequency anti-theft method for building voice-activated lamp power supply

Abstract

A variable frequency anti-theft device and method for a building voice-activated lamp power supply can make the building voice-activated lamp power supply intermittently output, generate a power supply that does not meet the standard frequency requirements, and make household appliances unusable without affecting the normal lighting of the voice-activated lamp. , so as to achieve the purpose of preventing electricity theft. Install a 4-way or 8-way multi-way switch device on the source fire wire of the building voice-activated light power supply, change the live wire of the building voice-activated light power supply from one way to a 4-way or 8-way parallel connection, and pass a reset function at the other end of the source fire wire. The multi-way switch device includes two parallel building voice-activated lights, and the other ends of the building voice-activated lights are connected together and connected to the source zero line of the voice-activated lights; the device also includes a reset restart output switch that automatically resets every 3min to 5min. Both ends of the reset and restart output switch are connected in parallel with the reset and restart ends of the second multiplexers.

Description

technical field [0001] The invention relates to a frequency conversion type anti-theft electricity method for a building voice-controlled lamp power supply. Background technique [0002] In order to facilitate the residents of the building to go home at night, the building is equipped with a voice-activated lighting system. The building's voice-activated lighting system is powered by an independent building voice-activated lighting power supply, and the power supply company does not charge additional electricity charges to the building residents. At present, many users of old buildings that have been in disrepair for a long time have been stealing electricity. They privately pull wires from the power source of the building voice-activated lights to enter their homes for charging, lighting, and household appliances of their own electric vehicles, which greatly increases the load on the power source of the voice-activated lights in the building. , Overloaded electricity will r...

AI Technical Summary

Problems solved by technology

At present, many old building users who have been in disrepair for a long time steal electricity from the power supply of the building voice-activated light to enter the house privately for charging their own electric vehicles, lighting, household appliances, etc., which greatly increases the load on the power supply of the building voice-activated light. , the overload of electricity will reduce the insulation of the power cable of the building's voice-activated lights, which can easily cause a fire. At the same time, this kind of electricity theft has caused huge economic losses to the power supply company.

At present, there are many old buildings that have been in disrepair for a long time, and the means of stealing electricity are concealed. The purpose of preventing electricity theft cannot be achieved by on-site inspection alone.
