Anti-electric shock multipath output intelligent switch

Abstract

The invention discloses an anti-electric shock multipath output intelligent switch, and relates to the field of intelligent switch circuit structures. The switch 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, so that the original household live wire is changed into a household zero wire, the household zero wire is changed into a household live wire, electric shock and tripping are avoided when a human body touches a single live wire, multi-path preset current output is achieved through the output circuit module, and the classification control requirement of a user for household electric appliances is met.

Description

technical field [0001] The invention belongs to the field of intelligent switch circuit structure, in particular to an electric shock-proof multi-channel output intelligent switch. Background technique [0002] With the rapid development of science and technology, there are more and more electrical equipment, and the number of accidents caused by electric shocks and even casualties remains high every year. Therefore, electricity safety has become a key concern in electrical equipment. Among the electric shock accidents that have occurred, the number of accidental electric shock accidents with household electricity is large. For those skilled in the art, it is very important to invent an electric shock-proof and fire-proof electric safety manager for household circuits to avoid accidental contact with live wires and cause electric shock casualties. necessary. However, the existing air switches and leakage protectors are all mechanical switches with low sensitivity and slow ...

AI Technical Summary

Problems solved by technology

However, the existing air switches and leakage protectors are all mechanical switches with low sensitivity and slow response time. There are multiple switches and leakage protectors in one switch box, and many wirings make installation inconvenient and prone to poor contact and The heating phenomenon of wires is easy to cause fire, so the use of existing air switches or leakage protectors to ensure the safety and reliability of household electricity is not enough
