Abstract

The invention relates to an alternating current socket with overvoltage protection. The alternating current socket with the overvoltage protection is formed by a voltage stability control circuit and a voltage monitoring circuit, wherein the voltage stability control circuit provides a stable power for a control output circuit by using a capacitor to reduce voltage and then passing through a full-wave rectification circuit and a voltage stability circuit, and the voltage monitoring circuit provides a reference voltage signal for the control output circuit by monitoring voltage of an input power. The alternating current socket with the overvoltage protection can directly cut off household power to timely protect household electric appliances from being destroyed when voltage of the household power is too high.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an AC socket with automatic overvoltage protection function. Background technique [0002] At present, household lighting power supply and household appliance power supply are both 220V AC power supply. Sometimes the voltage is too high or too low during use. When the voltage is too low, it will affect the normal use of household appliances, but generally it will not cause damage to household appliances. damage. If the voltage is too high, the life of household appliances will be greatly shortened, and in severe cases, household appliances may be damaged. Sometimes the neutral line of the outside line is broken, and the 380V AC will be strung together, and the 220V household power supply voltage will rise to 380V, directly burning household appliances. When the situation is serious, it will also trigger a fire, causing direct economic losses to people's houses and property, ...
