Zusammenfassung: | The utility model discloses an anti-electric shock multipath output intelligent switch, which relates to the field of intelligent switch circuit structures and comprises a main control chip, a power supply circuit module, a conversion circuit module, a fault detection circuit module, an output circuit module, a first operational amplifier chip and a second operational amplifier chip. After a person touches the household single live wire, the fault detection circuit module detects zero-sequence current, and the main control chip quickly disconnects the connection between the commercial power live wire and the household first power line, disconnects the connection between the commercial power zero wire and the household second power line, connects the commercial power live wire and the household second power line, and connects the commercial power zero wire and the household first power line. An original household live wire is changed into a household zero wire, the household zero wire is changed into a househo |
