Scientifically speaking, what do you think is the principle of electric barrier?

Safety nursing is to use the relationship between physical voltage and resistance, by extending the waterway and then extending the role of water resistance, the voltage is constant and the current is reduced. Based on the relationship between physical voltage and resistance, the effect of water resistance is prolonged by extending the waterway, and the voltage is constant while the current is reduced. Generally speaking, water is a conductor, and it is very dangerous to contact electricity. In fact, any object has resistance, so under the premise of economy, it may be transformed into a tool to meet human needs and benefit mankind. This is the case with "insulation wall" (that is, water resistance attenuation isolation method), which uses the resistance of water itself (for example, the national standard stipulates that the resistivity of tap water should be greater than1300 Ω. Cm in 15℃), and the diameter and distance of water pipes in the electric water heater are determined by selecting materials (thermal insulation materials) to form a "thermal insulation wall".

When the electric water heater is electrified, even if there is electricity, the water in the heating water tank will be attenuated by the resistance of the water itself when it passes through the "insulation wall", so as to achieve the purpose of isolating electricity, so that the water inlet and outlet ends of the water heater can reach almost zero voltage and extremely weak current below 0.02mA/kw. Using the function of "anti-electricity wall" technology, not only can the electric water heater itself be blocked from electric leakage, but also the security threat caused by live ground wire or water pipe to the shower can be blocked. Therefore, the water heater adopts the technology of "insulation wall", which fully ensures the safety of people's bathing. Anti-electric wall technology is a patented technology of water heater safety, which is based on the comprehensive application of pipeline design technology, raw material technology and electric resistance technology. It mainly includes the following aspects: the internal anti-electricity design, the selection and installation of heating pipes, magnesium rods, temperature controllers and other components in the water heater adopt special insulation treatment to ensure that the electricity in the water will not leak; External anti-electricity design The shell, mixing valve, nozzle and hose of the water heater have undergone special anti-electricity treatment to ensure the insulation of the contact part with the human body. Anti-electricity design of pipeline The pipeline of water heater adopts raw materials with special formula, and damping technology is applied in the structural design of pipeline, even if the water in the water heater is charged; It can also ensure the safety of people taking a bath. Under the voltage of 220V, the leakage current is less than 1mA (international standard 5mA), and you can take a bath if there is leakage. Bearing capacity1.5 MPa; Temperature resistance 100℃; The water resistance is greater than or equal to1mω; Standard 4-tap.
