How does a surge protection system work? The signal surge protector consists of five parts: discharge gap, inflatable discharge tube, varistor, suppression diode and choke coil, which includes at least one nonlinear voltage limiting element. The following is how each component works. 1. Discharge gap. The discharge gap is generally composed of two metal rods exposed in the air separated by a certain gap. When the instantaneous overvoltage strikes, the gap is broken down and a part of the overvoltage charge is introduced into the earth to avoid the voltage rise on the protected equipment. 2. Gas discharge tube. The gas discharge tube is composed of a pair of cold cathode plates separated from each other and encapsulated in a glass tube or ceramic tube filled with a certain amount of inert gas (Ar). In order to improve the trigger probability of the discharge tube, there is a co-trigger in the discharge tube. This kind of inflatable discharge tube has two-pole type and three-pole type. 3. Varistor. The main component of the varistor, the metal oxide semiconductor nonlinear resistor, is considered to be very sensitive to the voltage when the voltage at both ends of the varistor reaches a certain value. Its working principle is equivalent to the series-parallel connection of several semiconductors Pmurn. 4. Suppression diode. The suppression diode has the function of clamping and limiting voltage, and it works in the reverse breakdown zone. Because of its advantages of low clamping voltage and fast response, the suppression diode is especially suitable to be used as the last stage protection element in the multi-stage protection circuit. 5. Choke coil. The choke coil is a common-mode interference suppression device with ferrite as the magnetic core. it is symmetrically wound on the same ferrite annular core by two coils of the same size and the same number of turns to form a four-terminal device. it has a large inductance for the common-mode signal, but has little effect on the leakage inductance for the differential- mode signal.
