Description

technical field [0001] The invention relates to the field of electronics, in particular to the field of commercial power monitoring systems. Background technique [0002] Electric energy is a convenient energy source, and its wide application has formed the second technological revolution in the modern history of mankind. It has effectively promoted the development of human society, created huge wealth for human beings, and improved human life. With the popularization of the power grid, household appliances are now used in every household, which has brought great changes to human life. [0003] However, with the continuous increase of electricity consumption, it is inevitable that the mains power supply will be unstable due to excessive load or aging power supply lines, which will affect the normal use of household appliances and even affect the service life. Therefore, at present, people usually use the mains monitoring system to monitor the changes of the mains. However,...

Problems solved by technology

[0003] However, with the continuous increase of electricity consumption, it is inevitable that the mains power supply will be unstable due to excessive load or aging power supply lines, which will affect the normal use of household appliances and even affect the service life.

Therefore, at present, people usually use the mains monitoring system to monitor the changes of the mains. However, the current mains monitoring system is mainly composed of a mains rectifier unit, a mains voltage sampling unit, and a signal power amplifier isolation unit. The signal power amplifier isolation unit is usually composed of The other units of the system supply power, the circuit structure is complicated, and for the monitoring of the mains power, the monitoring is the mains voltage after the isolation of the signal power amplifier, which affects the monitoring speed and cannot be switched to the emergency power supply in time, which will cause property loss and casualties

[0004] Therefore, the defect in the prior art is that the signal power amplifier isolation unit in the mains monitoring system is usually powered by other units of the system, the circuit structure is complicated, and the wiring is complicated
