Multifunctional Interference-Resistant Protection Device-Jiangsu Laibao Electric Power Co., Ltd.

Multifunctional Interference-Resistant Protection Device

Drawing on years of research and development and optimized nanomaterial formulations, our company has developed a multifunctional anti-interference integrated protector capable of mitigating high-frequency interference, harmonic overvoltage, and overvoltage caused by switching pulses, lightning strikes, and surges.

Product Overview

Working Principle

During normal system operation with stable voltage, no current flows through the protector; it remains in a cut-off state with zero leakage current, ensuring no impact on the normal operation of the equipment within the protected system.

①　When harmonic or switching-induced overvoltages occur in the circuit, the voltage—once it slightly exceeds the normal operating level (e.g., a 450V protection threshold for a 400V system) and reaches the trigger point of the nanomaterial channel—causes the channel to conduct, thereby discharging the overvoltage that exceeds the rated protection limit.

②　When lightning strikes or surge overvoltages occur, the associated energy levels are extremely high; the resistance of the nanomaterial channel rapidly increases to block the current flow, while the ZnO channel activates to quickly shunt the high-energy surge to the ground, ensuring the safe operation of system equipment.

③　When high-frequency interference is present on communication lines, the nanomaterial channel conducts to dissipate the interference, thereby safeguarding the reliable operation of the equipment.

Applications

High-rise buildings and industrial plants; environments prone to switching-induced pulse overvoltages (such as welding operations); hospitals, data centers, and renewable energy facilities (photovoltaic and wind power); sites with high harmonic levels; elevators, mining equipment, and 5G communication base stations.
