Surge Protector Of Main Parameters

Feb 18, 2017

1, surge protector: rated voltage line protection system, this parameter indicates the information technology system should choose the type of protector, it marked the effective value of AC or DC voltage.

2, rated voltage Uc: impose protection specify the port for a long time, without causing the protection characteristics of the maximum voltage value and activate the protection component.

3, rated discharge current Isn: put on protectors waveform is 8/20 when the standard lightning impulse 10 μ s, inrush current peak protector the maximum tolerance.

4, the maximum discharge current Imax: put on protectors waveform is 8/20 μ s when the standard lightning impulse 1, protection that are well tolerated by most current peaks. 

5, Voltage protection level Up: maximum protector in the following test: 1KV/μ s slope of the flashover voltage; residual voltage of rated discharge current.

6, response time, tA: the main reaction in the protection to the special protection unit sensitivity and breakdown time, change over time depending on the slope of the du/DT or di/dt.

7, data rate: transport how many bits in a second value, unit: bps; is the correct selection of lightning in a data transmission system of reference values, data transfer rate depends on system lightning protection of transmission.

8, Insertion loss is Ae: at a given frequency protectors to insert before and after inserting the voltage ratio.

9, return loss Ar: front wave protection equipment (reflection) is reflected, is a direct measure of protection devices compatible to the impedance of the system parameters.

10, the maximum vertical discharge current: refers to every line on the applied waveform 8/20 μ s when the standard lightning impulse 1, protection that are well tolerated by most current peaks.

11, the maximum horizontal discharge current: refers to line to line 8/20 μ s waveform applied between the standard lightning impulse 1 times, protection that are well tolerated by most current peaks.

12, line impedance: nominal voltage Un flows through the circuit protector impedance and reactance. Often referred to as "the system impedance".

13, peak discharge current: in two ways: nominal discharge current Isn and maximum discharge current of Imax.

14, leakage current: the 75-or 80-nominal voltage of DC current flows through the protector under the Un
