The three-phase composite overvoltage protector surge arrester SYB-ZR-6P is an overvoltage protection device designed specifically for overhead lines, aimed at protecting the line from damage caused by lightning overvoltage. In the power system, overvoltage is a common phenomenon, including temporary overvoltage, switching overvoltage, and lightning overvoltage.
Among them, lightning overvoltage, due to its suddenness and high energy, poses a particularly serious threat to overhead lines. In order to cope with this situation, a device is needed that can quickly guide and limit the overvoltage to a certain range when lightning overvoltage occurs, avoiding damage to the line. This is the main function of the three-phase composite overvoltage protector surge arrester SYB-ZR-6P.
The design characteristics of the three-phase composite overvoltage protector surge arrester SYB-ZR-6P give it significant advantages in lightning overvoltage protection. It uses zinc oxide resistors, which have nonlinear characteristics and can quickly conduct under high voltage, limiting overvoltage to a certain range. At the same time, the thermistor inside the lightning arrester can trigger a short-circuit device when the overvoltage energy is too high, further protecting the safety of the line.
In addition, the three-phase composite overvoltage protector SYB-ZR-6P also has a composite structure, allowing it to be used as both a lightning arrester and an overvoltage protector. This flexible design allows SYB-ZR-6P to be widely used in various power systems, whether it is urban power grids or transmission lines in remote areas, and can be effectively protected.
Overall, the three-phase composite overvoltage protector surge arrester SYB-ZR-6P is an efficient and reliable overvoltage protection device that plays an important role in preventing damage to overhead lines caused by lightning overvoltage.
