The Role Of Surge Protector
The role of surge protector - the advancement from a novice to a senior master. The reason for the surge protective device: surge protection. When encountering indirect lightning strikes, using large frequency conversion equipment, or when the electrical equipment is turned on instantly, the power grid in use will fluctuate, and this fluctuation of the power grid is called surge. Surge is also called sudden wave, which means an instantaneous overvoltage that exceeds the normal working voltage. In essence, a surge is a violent pulse that occurs in just a few millionths of a second. The existence of surge is one of the reasons for the failure of electrical appliances. Sometimes in thunderstorms, the home suddenly trips, or the equipment that is normally used is damaged for no reason, which is most likely caused by surge.
The role of surge protection device - the advancement from a novice to a senior master. The role of surge protector: The emergence of surge protector is to control the instantaneous overcurrent and voltage that suddenly rushes into the wire loop and signal transmission line within the range that the equipment can withstand, or to introduce strong lightning current into the earth to ensure that the equipment or system can work safely and stably without damage due to impact.
The role of surge protector - the progress from a novice to a senior master. The working principle of surge protector: The surge protector uses a nonlinear varistor. Under normal circumstances, the surge protector is in an extremely high resistance state, and the leakage current is almost zero, ensuring the normal power supply of the power supply system. When there is a lightning overvoltage or operation overvoltage in the power line, the varistor responds quickly in nanoseconds and is in a low resistance state, limiting the overvoltage amplitude to a lower level, thereby protecting the power supply equipment from damage by overvoltage. After the overvoltage, the resistance of the varistor is very large, thereby protecting the equipment from damage by overvoltage. In addition, many people think that it is the same as the lightning arrester, but in fact there is a big difference (there are detailed explanations in previous issues, please check the official website yourself).
The role of surge protector - the progress from a novice to a senior master. Classification of surge protectors: There are three main types of surge protectors on the market, voltage switch surge protectors, voltage limiting surge protectors and composite surge protectors. The most practical one is the composite surge protector, because it combines the dual advantages of voltage switching surge protector and voltage limiting surge protector, which is very powerful.
