Three-phase Combined Overvoltage Protector

The SMR-TBP series three-phase combined overvoltage protector is a high-performance overvoltage absorption device suitable for power systems of 35kV and below. It is an advanced protective electrical appliance for limiting lightning overvoltages and switching overvoltages. It is mainly used to protect the insulation of electrical equipment such as generators, transformers, switches, busbars, motors, and parallel capacitor banks from overvoltage damage. It provides effective protection against both phase-to-phase and phase-to-ground overvoltages.

1. Protects the insulation of electrical equipment such as motors, generators, transformers, switches, busbars, capacitors, and motor neutral points from overvoltage damage.
2. Features fast operation, flat voltage characteristics, low residual voltage, stable performance, and convenient assembly and maintenance.
3. Provides effective protection against both phase-to-phase and phase-to-ground overvoltages.
4. Can be used in conjunction with action counters and miniature overvoltage protectors.

Modular Design: The protector features a modular internal design, facilitating replacement and maintenance. This design improves system reliability and makes fault detection and repair easier.

Compact Structure: Its compact structure allows for easy integration into various electrical devices, saving space without affecting equipment performance.

Efficient Thermal Management System: Overvoltage protectors typically feature optimized thermal management designs, effectively dissipating heat and preventing performance degradation or damage due to overheating.

High Current Carrying Capacity: This protector is designed with a high current carrying capacity, capable of withstanding large transient currents, ensuring electrical equipment is not damaged under high-energy surges.

Multi-Stage Protection Design: Most overvoltage protectors employ multi-stage protection systems (such as pilot discharge and subsequent absorption protection) to improve protection effectiveness and extend service life.

Fast Response: Our overvoltage protectors have a short response time, quickly detecting overvoltages and immediately cutting off or absorbing them, protecting equipment from damage.

High Protection Performance: Provides multi-level overvoltage protection, effectively preventing damage to equipment from lightning strikes, power grid fluctuations, and voltage peaks during equipment startup and shutdown.

High Durability: Utilizes high-temperature and corrosion-resistant materials, enabling the protector to operate stably for extended periods in harsh environments, resulting in a long service life.

Energy Saving and Environmental Protection: Effectively reduces energy consumption in power systems and equipment, while also minimizing maintenance costs associated with equipment damage caused by overvoltage.

Wide Applicability: Suitable for various electrical equipment, household appliances, industrial equipment, and communication equipment, among other fields.
