Why do water heater accidents happen? Zhongshan Wanmite Electric Appliance Co., Ltd. can tell you that it is now home Electric water heater It began to be popularized, but followed by the leakage problem of social concern. And today we introduce the fast heating type Intelligent thermostatic water heater There are usually two kinds of electric leakage: one is that the power line collides with the conductive part of the housing, and the other is that the heat pipe shell is burned through and caused by water conduction. To prevent zero leakage of fast heating intelligent thermostatic water heater from the root, special attention must be paid from purchase to installation.
The leakage protection device generally requires that the power supply can be cut off quickly within 0.1 seconds when the leakage current reaches 15 ma, and the product designated by the manufacturer of integrated intelligent thermostatic water heater should be purchased, because the manufacturer has a better understanding of the safety performance requirements of the product.
In addition to connecting the circuit, the water heater is also inevitably connected to the water pipe. In some buildings with poor grounding or no grounding at all, some people will connect the grounding wire with the water pipe, and let the water pipe serve as the grounding of the building. In this case, if the electrical appliances in a household leak electricity, the water pipes of the whole building will be electrified, and the users who are using the water heater for bathing will be injured by the current introduced by the water pipe even though they unplug the plug of the water heater.
However, the power line of the water heater also contains a strand of ground wire that does not pass through the leakage protector. Theoretically, the ground wire is also set to ensure the safety of electricity use. However, in case of reverse connection of the live wire and ground wire, aging of the line, etc. during decoration, the ground wire does not pass through the leakage protector, and the current may drive into the water heater through the ground wire, Electric shock accidents are still inevitable.
