Problems solved by technology

However, because the safety grounding is not done well, and other faults make the water heater casing electrified, the current leakage protector will not trigger the tripping of the leakage protector when the leakage occurs, but there is no human body contact to form a path; only when the human body touches After the electric casing is charged, the leakage protector will trip after the circuit is formed, and at this time, the human body has already suffered an electric shock

Abstract

The invention discloses an intelligent electric water heater controller with leakage protection, which comprises an intelligent processing control circuit, a leakage detection circuit and a load relay, and the leakage detection circuit and the load relay are both electrically connected to the intelligent processing control circuit. The intelligent electric water heater controller with leakage protection of the present invention detects the leakage phenomenon through the fire zero leakage detection circuit and the ground wire leakage detection circuit, and the intelligent processing control circuit immediately cuts off the heating load, and cuts off the connection between the water heater shell and the external ground wire, so that The water heater is completely de-energized and disconnected from the external leakage electric device, so that there is no risk of electric shock to the water heater.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an intelligent electric water heater controller with leakage protection. Background technique [0002] Electric water heaters are products that use strong electricity. Whether the installation is scientific and whether the use is reasonable is related to personal safety. According to GB 50254-2014 Construction Standards for Low-Voltage Electrical Appliances in Electrical Installation Engineering, GB 13955-2005 "Installation and Operation of Residual Current Action Protection Devices", all electrical equipment must be installed with reliable protective grounding and leakage protectors. Grounding is to ensure that electrical equipment An electrical safety measure adopted for normal work and personal safety, which is realized by connecting metal wires to the grounding device. The function of grounding is mainly to prevent personal electric shock, damage to equipm...
