What is the principle of Haier water heater anti electric wall raw materials?

Because the general water heater only has anti-leakage protection, but the ground wire does not pass through the leakage protector, in case the ground wire is electrified, the current will be directly introduced into the inner tank, then after the filter of the anti-electric wall, even the voltage of 220V can be reduced to less than 12V, to ensure absolute bathing safety. It can protect against both forward and reverse leakage. b The principle of the electric wall:

To put it simply, the anti-electric wall is equivalent to installing a large resistance between the water heater and the human body, so that the voltage borne by the human body is reduced to less than 12V. And the national safety standard is 36V. Note:

The anti-electric wall does not trip when the electricity leaks, but filters out most of the voltage. "Anti-electric wall" is an abbreviation, and its exact expression should be "water resistance attenuation isolation method". The general impression is that water is a conductor and that contact with electricity is very dangerous.

In fact, any object has resistance, so it can be transformed into a device that meets people's needs and benefits mankind under the premise of being economical. Theoretically, it can block the leakage that may be generated by the electric water heater itself, and it can also block the safety threat to the shower due to the live ground wire or live water pipe. The inlet and outlet pipes of the electric wall water heater are made of PPR plastic pipes, which are insulating materials.

Select the conductive path of water of a certain length and diameter of the pipe to achieve a certain resistance. In the unlikely event of a leakage accident, the current flowing through the human body due to the large resistance of the "water". As long as the leakage of electricity through the human body does not reach the deadly current value, people can escape this catastrophe.

0 x2 x( 1 a- d, to put it in layman's terms, "the electric water heater anti-wall technology is actually to add a section of plastic pipe to the inlet and outlet pipes of the water heater, and use the principle of water resistance to reduce the current at the water outlet, so that the voltage flowing out is lower than the safe voltage of the human body." ”

Connect the ground of the case to the wall where the water heater is installed (make an expansion screw on the wall). This is the electric wall.

The electric wall is the inner tank (water storage tank) of the electric water heater that is connected to the earth (including the wall) to prevent the leakage current of the electric water heater from being transmitted to the human body through the water and causing electric shock.

The so-called anti-electric wall is an anti-leakage and anti-electric shock device. Because when using a shower or hot water, a water heater....Water....The human body....Once the water heater leaks, people will be electrocuted, and the "anti-electric wall" will play the role of electricity and water isolation.

The anti-electric wall has a certain effect, but the anti-electric wall has become outdated, and now there is a product called security thermostat on the market, which is more than 10 times the anti-leakage effect of the anti-electric wall, and can also prevent the tap water pipe and the wall from being electrified.

Summary. Hello dear! Haier water heater has its own electric wallHaier water heater has its own electric wall, the electric wall is the water inlet pipe on the water heater, and the outlet pipe is made of plastic pipes.

In this case, if the heating pipe is broken and leaks, the water released will be electrified, and the electricity will not die. But it is very dangerous, so you must buy one with a leakage protector, and the leakage protector must be installed in the electrical box at home, and the ground wire must be installed even if it is buried underground.

2. No matter how the business advertises, and no matter how powerful the wall is Haier, when using the water in the electric water heater, it must meet the requirements of reliable grounding of the ground wire (resistance to the ground is less than 4 ohms) and the leakage protection switch is in good working condition (press the test button every month to confirm that its working state is normal).

Does Haier water heater have its own anti-electric wall?

Dear, Haier water heaters have their own anti-electric walls. The electric wall is made of plastic pipes for the water inlet and outlet pipes on the water heater, and the general home decoration inlet and outlet pipes are buried in the wall with PPR plastic pipes, so it is basically useless, but the galvanized pipes and metal hoses are still effective as the inlet and outlet pipes. In this case, if the heating pipe is broken and leakage, the water released is electrified, and the electricity is not dead, but it is very dangerous, so you must buy one with a leakage protector, and the leakage protector must be installed in the electrical box at home, and the ground wire must be installed even if it is buried underground.

No matter how the merchant advertises it, and no matter how powerful the wall is that Haier has, when using the water in the electric water heater, it must meet both the reliable grounding of the ground wire (the resistance to the ground is less than 4 ohms) and the leakage protection switch is in good working condition (press the test button every month to confirm that it is working normally).

Do you need to install an additional anti-electric wall to write?

The anti-electric wall is mainly for the situation of poor electrical environment, such as no ground wire, ground wire live, water pipe live, inferior socket burned out, etc., when the above situations occur, the body is easy to be electrified, even if the water heater is installed with a leakage plug can not play a protective role. Therefore, the installation of an "anti-electric wall" can avoid **electric shock risk** caused by leakage due to poor electrical environment.

The principle of "anti-electric wall" is to use the resistance of tap water itself to form a large resistance through special insulating pipe fittings, so when the water heater leaks, when the electricity passes through the large resistance of water, the electricity has been divided, and the voltage acting on the human body has been under the safe voltage (36V), so it has not caused harm to people.

So it is needed.

What is the electric wall of Haier electric water heater for? In fact, can it be protected against electricity? Ensure good insulation and resistance between the live parts and the housing, as well as between the live parts and the accessible conductive parts.

Qualified electrical components are selected and rigorously tested. For example, each electric heater should pass the insulation resistance, resistance, exhaust current and other related tests before leaving the factory.

<> electric wall (i.e. the insulation method of water resistance) refers to the use of water resistance itself (e.g., the national standard stipulates that water resistance should reach 15 84451; much greater than 1300 ocm) and form an "electric wall" by freely selecting the material (insulation) of the water pipe of the electric heater, and determining the pipe diameter and distance. When the electric water heater is energized, even if there is electricity, the water that heats the internal tank will be softened by the resistance of the water itself when it passes through the "electric partition wall", so as to achieve the purpose of electrical insulation, in order to obtain the following completely zero voltage and very weak current on both sides of the water heater, which is much higher than the national standard.

The principle of the anti-electric wall is to connect a huge mass resistor between the human body and the water heater. The longer the anti-electric wall, the safer it is. Of particular note is the presence of a PPR plastic between the two input tubes.

In addition, there is a thin wire attached to the wall of the water heater. The principle of the grounding wire. In addition, there is no scheme for the water heater, and there is no electric wall with an anti-leakage plug.

Theoretically, the water heater can be used as long as the internal tank is not damaged. There is no need to worry about the service life of the electric wall.

"Electric wall" is an abbreviation, and its exact expression should be "water resistance mitigation method". In general, water is a conductor and is very dangerous to come into contact with electricity. In fact, any object has resistance and, therefore, under the premise of the economy, can be transformed into a tool to meet human needs and interests.

This is the case with "electric walls". Electric wall-to-wall technology not only stops the losses that can occur in the electric heater itself, but also stops the safety threat to the shower caused by ground wires or live water pipes. Therefore, the water heater adopts electric wall-to-wall technology, which fully guarantees the safety of bathing personnel.

Ensure insulation between the live parts and the housing.

The principle of Haier anti-electric wall water heater: the electric water heater forms a permanent resistance inside, so as to reduce the current value of the human body under abnormal circumstances, the ordinary standard voltage in China is 220V, and the maximum voltage borne by the human body after the anti-electric wall treatment is equivalent to 12V, which is lower than the safe voltage of the human body 36V, which ensures the safety of the human body.

Due to the long pipeline, the resistance value of the anti-electric wall water heater is relatively large, and the partial pressure of the upper Zheng elimination surface is quite high, and the partial pressure carried after going to the human body is relatively low, which is equal to 12V after calculation, which ensures the safety of the human body.

This answer is applicable to Haier EC6001-GC and Haier ES60H-HC3(E) brand water heater models.

The electric wall water heater is Haier's patented technology. In March 2002, Haier Electric Water Heater launched the "anti-electric wall" technology, which has the international leading level of "anti-electric wall" electric water heater, and took the lead in the domestic water heater industry to solve the environmental safety problems that have long restricted the development of the industry, such as "live ground wire", "live power socket of mold filial piety", "live water pipe".

The anti-electric wall is equivalent to installing a resistor between the water heater and the user, reducing the voltage to a range that is acceptable to the human body. In 2002, Haier invented and patented this technology. In 2007, the anti-electric wall technology became an international safety standard.

Answer:1The electric wall water heater is not Haier's patented technology. Haier may have its own water heater technology, but the electric wall water heater is not one of them.

2.Electrified wall water heaters are a ubiquitous technology, and many companies have similar products. This technology is designed to prevent the risk of electric shock by isolating the power supply from the water source.

3.Since there is no specific patent information, it is impossible to determine which company first developed the technology for the electric wall water heater.

4.The working principle of an electric wall water heater is usually to employ an insulation layer or isolation device between water and electricity to ensure that there is no direct contact between water and electricity to reduce the risk of electric shock.

5.Summary: The electric wall water heater is not Haier's patented technology, but a ubiquitous technology, and many companies have similar products. This technology protects the human body by isolating the power and water sources.
