Secure protector for power

Abstract

The invention discloses a safety power consumption protector, which can protect the circuit by automatically cutting of the power once the controlled circuit is too high and too low in voltage, and too heavy in current and the electric shock and electric leakage occur. The protector is composed of an electrically switchable grating (J1) and the control circuit thereof (6), a control component (D10) on the control circuit (6), an electrified press key (K1), a power cut-off press key (K2), a power source end junction column (a) of the electrically switchable grating (J1), a controlled end junction column (b or c), a voltage overtension control circuit, a lower voltage drop control circuit, an over intense current control circuit, an electric shock control circuit, an electric leakage control circuit, etc. automatic protection circuits. The protector in the second embodiment again supplies power after the power source end is power-off. If no body presses the electrified press key or an infrared remote control connection key, then a controlled line (2) can not automatically electrify, thus the household apparatus can not automatically work due to power supply.

Description

technical field [0001] The invention relates to a circuit safety protector, more precisely, it relates to a safety protection device for household electricity, and of course it can also be applied to the protection of some electrical appliances and circuits that need special protection. Background technique [0002] At present, with the continuous progress of society, the use of electricity is becoming more and more widespread in people's daily life, but the ensuing electric shock, fire, excessive voltage of transmission line or The incidents of electrical appliances being destroyed and burned due to too low voltage are increasing, which have brought serious threats and losses to people's lives and property. It is an electrical safety protection device that automatically protects power consumption conditions such as over-voltage, over-low voltage, over-current, electric shock, and leakage. Contents of the invention [0003] The purpose of the present invention is to use e...
