Problems solved by technology

[0002] At present, in remote mountainous areas and rural areas of our country, the grid voltage is extremely unstable, and the voltage is generally low. Some grid voltages are only about 120V. In such a grid, household appliances cannot be used normally and will greatly damage the life of electrical appliances. Although there are many voltage stabilizers on the market, the effect is not very good, and the price is high, and the volume is large. Now there are many smart sockets on the market that can play the role of automatic protection against overvoltage and undervoltage, but it is very difficult There are few sockets with voltage stabilization function

Abstract

The invention discloses a voltage-stabilizing socket circuit, comprising a chip U1, a chip U2, a rectifier bridge Q, a transformer T, a fuse FU, and a relay K1. The voltage-stabilizing socket circuit can stabilize voltage around 220V when voltage of electric supply is too high and too low (higher than 240V or lower than 170V). The circuit is simple in structure, low in cost, small in volume, and can be used by integrating in an ordinary socket. The circuit is very suitable for popularization and application.

Description

technical field [0001] The invention relates to a socket, in particular to a voltage stabilizing socket circuit. Background technique [0002] At present, in remote mountainous areas and rural areas of our country, the grid voltage is extremely unstable, and the voltage is generally low. Some grid voltages are only about 120V. In such a grid, household appliances cannot be used normally and will greatly damage the life of electrical appliances. Although there are many voltage stabilizers on the market, the effect is not very good, and the price is high, and the volume is large. Now there are many smart sockets on the market that can play the role of automatic protection against overvoltage and undervoltage, but it is very difficult There are few sockets with voltage stabilization function. Contents of the invention [0003] The object of the present invention is to provide a voltage stabilizing socket circuit with simple structure and low cost, so as to solve the problems...
