Working Mechanism of Surge Protective Device and Its Application Analysis
Yun Hu · Low Voltage Apparatus · 2013
Based on the structure,working mechanism and operating parameters of surge protective device,SPD for lightning surge pressure limiting and distribution mechanism were discussed,the application and analysis were also given.In the lightning environment,line SPD can make device work normally by limiting the transient over voltage and shunt surge current.It has guiding significance for protecting communication line and the connecting device.
