Monitor for intelligent electricity using

Abstract

The invention relates to a monitor for intelligent electricity using, which comprises an input line connecting port, an output line connecting port and a reset key, and also comprises a single-chip microcomputer and a pre-warning test key, an alarm test key and a signal indicator, which are connected with the single-chip microcomputer, wherein the single-chip microcomputer can compares values of voltage, leakage current, fault arc and electrical load with preset values to output corresponding signals to a sounding device, a power supply relay and the signal indicator. The monitor for intelligent electricity using can enable electricity use of families and merchants to be safer, and can effectively integrate unsafe factors in the electricity using process, such as overvoltage, leakage current, fault arc and overload into a whole for pre-warning and alarming, cut off the power supply timely and record and display the alarming every time to facilitate inquiring the reasons of electric accidents.

Description

technical field [0001] The invention relates to a safe and intelligent power utilization monitor, in particular to a safe and intelligent power utilization supervisor for monitoring and ensuring the safety of power utilization. Background technique [0002] At present, households and businesses use the mains 220v AC voltage, and there are mature technologies for monitoring leakage and overload, but the action time is long and the index accuracy is not high. There is a fault arc in the power circuit; the electrical equipment is damaged due to the sudden high voltage of the mains power; the power circuit and electrical products are aging, the insulation is reduced, and a sudden local short circuit occurs, which causes a fire. The existing monitoring technology is even more difficult to detect. Early warning and alarm as well as fast power cut off to prevent the occurrence of electrical accidents. Contents of the invention [0003] In order to solve the problems existing in...
