What is the general classification of the lightning protection module of the backup protector?
The general classification of lightning protection modules is as follows: According to the principle, the power switch type lightning protection module, its principle is to show a higher characteristic impedance overvoltage without transients, but once it responds to the lightning transient overvoltage, Its characteristic impedance will suddenly become low and is easy to consume, resulting in lightning strikes.The components of this type of equipment include: charge and discharge gap, gas discharge tube, thyristor, etc.. The principle of the voltage-limiting plate lightning protection module is to have high resistance without instantaneous overvoltage, but its characteristic impedance will vary with the surge current and operating voltage. As the current intensity increases, the impedance will continue to decrease, and its current intensity has a unique discrete system.As a component of this type of equipment, active zinc oxide and zinc oxide varistors, suppressor diodes, avalanche diodes, etc..
Nowadays, most lightning protection modules are pressure-limiting boards, and the previous batch of products used to shield electronic equipment are all used in the department. Separate or choke-type lightning protection module is a separate type: connected and used in series with the equipment to be maintained, the single pulse performance of lightning strikes for all normal output power, lower characteristic impedance and higher characteristic impedance. Choke type: in series with the equipment to be maintained, it shows high characteristic impedance in the form of lightning single pulse, and for all normal output power, it shows lower characteristic impedance. The equipment includes chokes, high-pass filters, and low Pass filter, 1/4 wavelength short circuit, etc..
Main uses: surge protector, AC power surge protector, DC power surge protector, power switch power surge protector equipment and other communications. Signal lightning protection device, high frequency signal lightning protection device, high frequency signal lightning protection device, antenna feeder lightning protection module, etc..The formation of a lightning electrical protection module, also known as a three-in-one lightning protection device, refers to a lightning protection device with a power supply lightning protection function that integrates video lightning protection and switches on the surveillance camera side of the video surveillance system. According to the lightning protection level, the general tolerance of the general standard is about 30KA.The general tolerance of the general standard is about 30KA.The difference is between 15-20KA, the general tolerance of the general standard is between 5–10KA
For all normal output power
