SPD varistor manufacturers believe that the application of varistors can significantly protect low-voltage electrical equipment. Generally speaking, in order to prevent lightning strikes, we need to take various lightning protection measures according to the specifications, and then install varistors at the user's power supply end to realize the resistance adjustment of the power supply end. If there is a large voltage at the power supply terminal, the varistor will be broken down to ensure that the voltage at both ends remains at a normal value, thereby protecting the electrical equipment. In addition, the phase line or neutral line is used to introduce lightning overvoltage, which can be broken down by two varistors, and the voltage at both ends will remain at a normal value. At the same time, the fuse will be blown to ensure that no continuous current flows through the varistor, thereby protecting the varistor.

Basic properties of varistors:

(1) Protection characteristics. When the impact strength of the impact source (or the impact current Isp=Usp/Zs) does not exceed the specified value, the limited voltage of the varistor is not allowed to exceed the impact withstand voltage (Urp) that the protected object can withstand. .
(2) Impact resistance characteristics, that is, the varistor itself should be able to withstand the specified impact current, impact energy, and the average power when multiple impacts occur one after another.
(3) There are two life characteristics. One is the continuous working voltage life, that is, the varistor can meet the specified working time (hours) under the specified ambient temperature and system voltage conditions. The second is the impact life, that is, the number of times it can reliably withstand the specified impact.

Application

1. Varistor voltage: refers to the voltage value across the varistor at a specified temperature and DC (generally 1mA or 0.1mA). Recorded as V1mA or V0.1mAo
2. Maximum continuous voltage: refers to the maximum effective value of sinusoidal AC voltage or the maximum DC voltage value that can be continuously applied to both ends of the varistor for a long time under the specified ambient temperature
3. Limiting voltage: refers to the maximum peak voltage at both ends of the varistor when a specified surge current (8,20μs) passes through it.
4. Rated power: refers to the maximum average impact power that can be applied to the varistor under the specified ambient temperature.
5. Maximum energy: the maximum impact energy that can be applied to the varistor under the condition that the varistor voltage does not change more than ±10% and the impulse current waveform is 10, 1000μs or 2ms.
6. Current capacity (maximum inrush current)
