Problems solved by technology

[0002] At present, most water heaters are equipped with a conventional leakage protection function. This function can only solve the problem of immediately cutting off the power supply system when there is an abnormal leakage in any pole of the phase power supply, but cannot report the cause of the abnormality and perform corresponding protection. Self-check the system to achieve real leakage detection and protection

Abstract

The invention discloses an intelligent electric leakage detection protecting device. A phase line-ground wire electric leakage voltage detection module is used for detecting the condition of voltage between a phase line and a ground wire and transmitting information to a MCU (Micro Control Unit) control centre; a zero line-ground wire electric leakage voltage detection module is used for detecting voltage between a zero line and a ground wire and transmitting information to the MCU control centre; the MCU control centre controls an electric leakage current detection module to operate; the electric leakage current detection module detects the electric leakage current state of the phase line and the zero line and transmits information to the MCU control centre; the ground wire is provided with a relay; the MCU control centre is provided with a control chip internally; and a control program is burnt in the control chip; according to the received information, the MCU control centre respectively controls an LCD display module and a buzzer alarming module to operate and controls the on / off of the relay by virtue of the control program. The intelligent electric leakage detection protecting device can be used for carrying out the comprehensive intelligent electric leakage and corresponding protective measures on an electric water heater.

Description

technical field [0001] The invention relates to the field of electric water heater leakage detection, in particular to an intelligent electric leakage detection and protection device. Background technique [0002] At present, most water heaters are equipped with a conventional leakage protection function. This function can only solve the problem of immediately cutting off the power supply system when there is an abnormal leakage in any pole of the phase power supply, but cannot report the cause of the abnormality and perform corresponding protection. Self-check the system to achieve real leakage detection and protection. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an intelligent leakage detection and protection device, which can realize comprehensive intelligent leakage detection of electric water heaters and implement corresponding protection measures. [0004] The technical scheme that the present i...
