Zinc oxide lightning arrester is a commonly used power equipment, which can effectively protect the power system from the harm of lightning strikes. This article will introduce the working principle of zinc oxide lightning arrester to help readers better understand this equipment.
1. Basic principle of zinc oxide lightning arrester
1.1 Conductivity of metal oxides: The main material of zinc oxide lightning arrester is zinc oxide, which has good conductivity and can discharge quickly when struck by lightning.
1.2 Blocking high voltage voltage: Zinc oxide lightning arrester is a high impedance device under normal circumstances, which can block the passage of high voltage voltage.
1.3 Discharge protection: When struck by lightning or the voltage is too high, the zinc oxide lightning arrester will discharge quickly, lead the overvoltage to the ground wire, and protect the power equipment from damage.
2. Working process of zinc oxide lightning arrester
2.1 Static working state: Under normal circumstances, the zinc oxide lightning arrester is in a high impedance state and does not conduct electricity.
2.2 Dynamic working state: When the system is struck by lightning or the voltage is too high, the zinc oxide arrester will discharge quickly, lead the overvoltage to the ground wire, and protect the equipment.
2.3 Restore working state: Once the overvoltage disappears, the zinc oxide arrester will automatically return to the high impedance state and wait for the next lightning strike.
3. The protective function of zinc oxide arresters
3.1 Protecting power equipment: Zinc oxide arresters can effectively lead lightning strikes or overvoltage to the ground wire to protect power equipment from damage.
3.2 Prolonging equipment life: By discharging in time, zinc oxide arresters can reduce the number of times the equipment is struck by lightning or overvoltage, and prolong the service life of the equipment.
3.3 Improving system reliability: The protective function of zinc oxide arresters can improve the reliability of the power system, reduce the number of power outages, and ensure stable power supply.
4. Application fields of zinc oxide arresters
4.1 Power system: Zinc oxide arresters are widely used in power systems to protect important equipment such as transformers and switchgear.
4.2 Communication system: Zinc oxide arresters are also commonly used in communication systems to protect communication equipment from the hazards of lightning strikes.
4.3 Industrial equipment: In the industrial field, zinc oxide arresters are also widely used to protect various types of equipment.
5. Development trend of zinc oxide arresters
5.1 High performance: In the future, zinc oxide arresters will develop in the direction of high performance, improving their lightning resistance and discharge speed.
5.2 Intelligence: With the development of Internet of Things technology, zinc oxide arresters will also be intelligent, able to monitor the status of equipment in real time and perform remote control.
5.3 Greening: In the future, zinc oxide arresters will pay more attention to environmental protection performance, reduce the impact on the environment, and promote the development of green energy.
In short, zinc oxide arresters, as an important power equipment, have good protection. By understanding its working principle and development trend, it can be better applied to actual production and improve the reliability and safety of the power system.
