Is the diameter of the varistor related to the flow rate?

Everyone is well aware that the raw material of the varistor is made of a resistive semiconductor, so it is also one of the resistors. There is a lot of zinc oxide produced in the varistor during use. Its main material is the synthesis of two elements and six elements. The technician will apply the varistor to the power circuit to protect the voltage and prevent the occurrence of electric shock. This will help protect the leased voltage, which is usually combined with the current fuse device.

So, is the diameter of the varistor related to the flow? The larger the diameter of the varistor, the higher the through-flow. Pressure-sensitive resistor manufacturers usually rely on guidelines to implement the pressure-sensitive dredge. That is to say, according to the pressure sensitive principle, the impact rate of the varistor voltage is not higher than 10% by using 2/5 waveform impact. It is passing. One of the varistor's through-flow criteria is 2/5 waveform shock 2500A once and 1250A twice. Another pass criterion is 2/5 waveform impact 4500A once and 2500A twice.

If the circuit is not the same, the input voltage and current will be different. Excessive current can destroy important devices. The varistor is a voltage limiting protection device in a special voltage range. It is a key point, adding a persistently high varistor voltage value, and not presenting such a high transient voltage in real use, it cannot be used properly. function. When the voltage is low, it will often be in the work situation. Not only the service life will be affected, but also it will be burned out.

The larger the diameter of the varistor, the higher the through-flow. According to the guidelines, the varistor manufacturer's dredge of pressure sensitive is usually implemented. That is to say, according to the pressure sensitive principle, the impact rate of the varistor voltage is not higher than 10% by using 2/5 waveform impact. It is passing. Different circuits, different voltage and current. Excessive current can destroy important devices.
