Variable-frequency electricity larceny prevention device and method for building sound control lamp power supply

Abstract

The invention discloses a variable-frequency electricity larceny prevention device and method for a building sound control lamp power supply, and the device and method can enable the building sound control lamp power supply to achieve the intermittent output, generate a power supply which does not meet the standard frequency requirements, enable a household electrical appliance not to be used while not affecting the normal illumination of a sound control lamp, and achieve the purpose of electricity larceny prevention. Four or eight paths of multi-path change-over switch devices I are arrangedon a source live wire of a building sound control lamp power supply; a live wire of a building sound control lamp power supply is changed into four or eight paths from one path to be connected in parallel, the other end of a source live wire is connected with a building sound control lamp in parallel through a second multi-path selector switch device with a reset function, and the other ends of all building sound control lamps are connected together and connected with a source zero line of the sound control lamp; the device further comprises reset and restart output switches which are automatically reset once every 3-5 min, and the two ends of the reset and restart output switches are connected with the reset and restart ends of the second multi-way change-over switches in parallel.

Description

technical field [0001] The invention relates to a frequency conversion type anti-stealing electricity device and method for a building sound-activated lamp power supply. Background technique [0002] In order to make it easier for building residents to go home at night, the building is equipped with a voice-activated lighting system. The building voice-activated lighting system is powered by an independent building voice-activated light power supply. The power supply company does not charge additional electricity charges to building residents. 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 th...

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.
