Intelligent home electrical appliance and automatic power reclosing protection breaker

Abstract

The invention relates to an intelligent protection circuit breaker with automatic switch-on for household electric appliances and power supply, which comprises an air circuit breaker, a power circuit, a voltage sampling circuit, a temperature sampling and transferring circuit, a leakage sampling and transferring circuit, an electric potential comparison circuit, a given voltage circuit, a failure indicating and alarming circuit, a prompt start circuit, an automatic (delay) start circuit, an operation indicating circuit, a driving circuit, an executing agency, an output wiring terminal, an electric machine, a crate and a detecting circuit. The invention can protect household electric appliances, power supply and transmission line omni directionally and also can monitor a plurality of physical quantities like power voltage, loading circuit, leakage current, lightning induction and exotherm at the same time to ensure the physical quantities running under monitoring. The protection functions of the invention can amount to 12 types. The invention ensures no leakage voltage which is dangerous for personal security in an electric apparatus coat, and the exotherm of a power cord accords with national standard. The invention is safe and reliable and is inexpensive in cost. The invention can close the switch again automatically when failures are removed.

Description

1. The technical field to which it belongs; [0001] The invention belongs to the technical field of protectors, and the name is an intelligent household appliance, a power supply automatic reclosing protective circuit breaker (hereinafter referred to as a protective circuit breaker). With the advancement of my country's four modernizations, a large number of daily-use and household appliances have entered the fields of thousands of households, entertainment venues, hotels, restaurants, health care, decoration industries, colleges and universities, and the power consumption is increasing. And multi-series single-phase 220v power supply. [0002] "Electricity" not only adds color to people's life and improves the quality of life, but also brings confusion, even disaster and pain to people, so "electricity" is jokingly called "toothless tiger". Due to the low quality of power supply, aging or damage of insulation, certain weaknesses and defects of various electrical appliances, im...

AI Technical Summary

Problems solved by technology

When the fault is eliminated and the original rated operating conditions are restored, the leakage circuit breaker cannot be automatically reclosed for power supply, and manual closing is required, which will cause inconvenience to users and even property loss
