Suzhou electric water heater safety protection awareness is very important

Suzhou electric water heater safety protection awareness is very important

(1) Protective ground


220V single-phase civil power supply only has phase and neutral wires. According to civil construction standards, there should be an independent grounding protection wire in civil power supply lines, which is a facility that civil buildings must be equipped with, and has nothing to do with the power grid. The protective grounding of electrical appliances refers to the reliable connection between the shell of the electrical equipment and the ground protection wire. Once the equipment's insulation is damaged, the equipment's shell has dots, and its potential is basically zero due to reliable contact with the ground. When the human body touches the shell, the current flowing through the human body is very small, and there is no danger;


(2) Zero-connection protection


When the building is not equipped with a ground protection line, there are also zero lines as protection lines, which is called zero-connection protection. When using zero-connection protection, the protection wire must be directly connected to the neutral wire, and it is not allowed to be connected to the neutral wire in the socket.


(3) Leakage protection switch


In the normal electrical circuit, the current intensity of the neutral line is the same and the direction is opposite. When the electrical appliance has a leakage current, the current of the live wire and the neutral wire are not equal, and the leakage protection switch immediately opens to cut off the power. In some old buildings, there is no ground wire. When installing electrical appliances, a leakage protection switch should be installed.


(4) Frequent comprehensive safety inspections of electrical equipment


Check for leakage, check the degree of aging of the insulation, check for exposed parts, and check the installation of the equipment for violations.
