Varistor to suppress surge appliance protection

I believe that everyone's protection against surges in varistor is very clear. What kind of protection state is the varistor in the household capacitor? The editor will introduce you in detail, let's look down!

At present, most of the household appliances we use are basically single-phase power supply. This kind of power supply method is simply to place a varistor between the phase line and the neutral line to simply use it as an overvoltage protection component. Lateral protection, that is, differential mode protection as opposed to full mode protection, is only insufficient to rely on differential mode protection as an overvoltage protection component.

We all know that the surge of power is not only from lightning strikes. Sometimes, when the power system is short-circuited, power surges will occur. Imagine that the power grid is very large, so it is from lightning strikes. The power surge is also caused by the power surge caused by the short circuit of the power itself. The probability of occurrence is very large. When a lightning strike occurs in a far place, the surge generated by the lightning strike is filtered through the circuit layer. When arriving at the user's home, the power is still very large, which will damage the household appliances and some household appliances that need electricity.

In order to prevent these damages, we must suppress these overvoltage surges or eliminate overvoltage surges to prevent the insulation of electronic circuits from being damaged. We need to install a full-mode protection, also known as It is longitudinal protection.

The surge suppression protection of varistor is also very familiar to everyone. When purchasing varistor, remember to choose a guaranteed manufacturer to ensure the quality of the product.
