Surge protector, also known as lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. When the peak current or voltage is suddenly generated in the electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, so as to avoid the damage of the comic mode surge to other equipment in the circuit.
Surge protector, suitable for AC 50 60Hz, rated voltage 220V 380V for the power supply system, indirect lightning and direct lightning impact or other instantaneous overvoltage surge protection, suitable for family housing, tertiary industry and industrial surge protection requirements.
Development history: The most primitive surge protector horn-shaped gap, which appeared in the late 19th century, was used for overhead transmission lines to prevent lightning strikes from damaging equipment insulation and causing power outages. In the 20s of the 20th century, aluminum surge protectors, oxide film surge protectors and pill surge protectors appeared.
Tubular surge protectors appeared in the 30s. Silicon carbide surge protectors appeared in the 50s. In the 70s, metal oxide surge protectors appeared.
Modern high-voltage surge protectors are used not only to limit overvoltages caused by lightning in power systems, but also to limit overvoltages caused by system operation. Since 1992, the industrial control standard 35mm rail snap-in pluggable SPD lightning protection module represented by Germany and France has begun to be introduced to China on a large scale, and later the integrated box-type power supply lightning protection combination represented by the United States and Britain has also entered China.

Surge protector, also known as lightning protector, is a kind of differential bright electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines.
Surge protector functionWhen the electrical circuit or communication line is in the state, due to external interference suddenly produces a peak current or voltage, the wave virtual trace wide surge protector can be turned on and shunted in a very short time, so as to avoid the surge damage to other equipment in the circuit. The location of the surge protector plays an important role in the protection of transmission lines and electronic components. Products containing surge blocking devices can effectively absorb bursts of tremendous energy to protect connected devices from damage.
Scope of applicationThe surge protector is generally suitable for AC 50 60Hz, rated voltage 220V 380V power supply system, indirect lightning and direct lightning impact, or other instantaneous overvoltage surge protection, suitable for family housing, tertiary industry and industrial surge protection requirements.

Pro, a surge protector is an electrical protection device that is usually installed at the incoming position of the power system to protect the subsequent terminal equipment from sudden voltage surges (surges) in the power system. It can reduce the voltage peak before the voltage caused by factors such as the trip of the switch of large electrical equipment and the sudden power failure of electronic equipment, and the instantaneous state-only overvoltage that exceeds the internal tolerance of the equipment. The main functions of the surge protector are as follows:
1.Protection of power-consuming equipment: The surge protector can prevent the peak value of voltage and overvoltage from affecting the power-consuming equipment instantaneously, protect the stable operation of the equipment, and prolong the life of the equipment.
2.Protection of electrical equipment: Surge protectors can protect, maintain and repair electrical equipment, reducing maintenance costs.
3.Protection against lightning intrusion: In the event of lightning or sudden electrical network failure, surge protectors can prevent sudden currents from entering the electrical system and protect equipment.
4.Error Protection: Surge protectors protect circuits when transient overvoltages are caused by misoperation of electronic devices, such as miswiring and man-made damage.
In short, surge protector is an important electrical equipment to protect electrical equipment and prevent sudden voltage, which can protect the safe and stable operation of the power system and subsequent terminal equipment to the greatest extent.
Surge protector is a device commonly used to limit the overvoltage of lightning waves, and is commonly used in the power supply system of 220V and 380V power supply. According to the different working principles, surge protectors can be divided into two types: voltage switching surge protectors and voltage limited surge protectors. >>>More
When the lightning comes, the varistor of the surge protector will reduce the resistance, so as to drain the current.
Overvoltage protection type leakage circuit breaker is used for overvoltage protection.
Inrush current refers to the current characteristics of electrical equipment at the moment of switching, which is very important for the safety of power supply network and electrical equipment. Inrush current suppression is often required in engineering. >>>More
Protective grounding. It is a grounding to prevent the metal shell of electrical installations, the frame of power distribution devices and line towers from being electrified and endangering the safety of people and equipment, and it is a measure to grounding the metal shell of electrical equipment. It can prevent strong current from passing through the human body when the metal shell is energized in the case of insulation damage or accidents, so as to ensure personal safety. >>>More
