In view of the emergence of various types of lightning arresters on the market, the quality is uneven, and some are even unheard of (such as: lightning arresters without grounding, until now, can not understand how it works), so By introducing the working principle and composition of the arrester, it is helpful to identify the true and false, good and bad customers.
The lightning arrester components are available in both soft and hard from the perspective of response characteristics. The discharge element belonging to the hard response characteristic has a spark gap (angular spark gap and coaxial discharge spark gap based on xenon arc technology) and a gas discharge tube, and the discharge element belonging to the soft response characteristic has a metal oxide varistor and transient suppression. diode. The difference between these components is the discharge capacity, response characteristics and residual voltage. The arresters use their different advantages and disadvantages, and they are combined to form various arresters and protect circuits.
