With the continuous improvement of science and technology, many water heaters have the function of an anti-electric wall. What is the electric wall of the electric water heater ? Is it good or bad? Next, let's take a look at the contents of the wall of the electric water heater .
What is the electric water heater protection wall?
"The electric wall" is the use of the water itself has the resistance (such as the national standard rules of tap water resistance at 15 °C when the resistivity should be greater than 1300Ω.cm), after the selection of the insulating material in the water heater inside the water pipe, making the diameter and tube There is an "electric wall" between the walls. When the water heater is energized, the water that heats the bladder will be attenuated by the resistance of the water itself when it passes through the “anti-electricity wall†and reaches the intention to separate the resistors, so that the water heater enters and exits the water to reach zero. The voltage and extremely weak current below 0.02mA/kw are much better than the national standard 0.25mA/kw.
Electric Water Heater Protection Wall Working Principle
For some reason, the voltage of the water in the bladder of the water heater is 220V. When the ordinary water heater flows out of the water, it will cause a voltage difference of 220V on the human body. This will cause great harm to the human body, and Haier Anti-electric wall water heater, the water in his gallbladder does not directly flow out, but flows out after a relatively long period of water pipes. As the length of the pipeline increases, the resistance of the water in the pipe also increases, so that the gallbladder Water flows through the longer pipeline to the human body, which is equivalent to a series circuit. Since the pipeline is relatively long, its resistance value is also relatively large, and then its partial pressure is quite high, and then the partial pressure on the human body. Relatively speaking, it is relatively low. After calculation, the partial pressure on the human body is about 12V. This kind of voltage will not cause any harm to the human body. This effectively protects people's safety.
Electric water heater protection wall limitations
1, can protect the ground due to live, water heater failure leakage, but if it is not properly installed, can not protect the electric water from the water pipe and the resulting shock.
2. The tap water must be of sufficient purity. Due to China's vast land and resources, and the disparity in development, some areas may have relatively poor water quality, so the discharge wall can hardly function.
3, if the user is a false ground, at the same time due to electric water heater leakage caused by the ground line with the fire, the user's home appliances may be charged, as a potential accident.
Regarding the electric water heater wall , I will introduce it to you. I hope to help you, and I would like to look forward to seeing more information on this site.
