Description

過電壓保護（Surge Protection）是指用於保護電子設備免受突發的過電壓損害的技術或裝置。過電壓是指電力系統中出現的瞬間電壓過高的情況，可能是由於閃電、電力瞬間恢復或其他電力干擾所引起。這些過電壓可以導致嚴重的損壞或故障，影響連接的電子設備的性能甚至使其完全損壞。Overvoltage protection (Surge Protection) refers to the technology or device used to protect electronic equipment from sudden overvoltage damage. Overvoltage refers to a situation where the voltage is too high momentarily in the power system, which may be caused by lightning, instantaneous power restoration, or other power disturbances. These overvoltages can cause severe damage or malfunction, affecting the performance of connected electronic equipment or even causing it to completely fail.
