AC电源Sidactor泄流保护方案

220VAC

MOV+TSS(Sidactor) decrease Vc

MOV block short current@TSS On State

Surge Without AC Input Surge With AC Input

Note:TSS Leakage <<MOV Most Open Volt on TSS Possible TSS malfunction Cause MOV Conduct on Short Current Damage

MOV;Thus,Make Cetain Sidactor block timely is significant ;MOV Vnom >TSS Vs gurrantee TSS close

So what is the “ideal” device and can we make it?

The “Ideal device” would have no leakage current in the normal operating region

And clamping voltage is equal or close to VR ( standoff voltage )

This solution is to combine crowbar with MOV to offset high clamping voltage of

MOV , increase block voltage and reduce leakage to nA level

DC power protectionFor the features of DC feeder, DC ports should be taken the following

protection measures particularly.

Feeder cables from RRU should have DC SPD and then access into

DC power cabinet.

Shielded cable should be adopted for power lines and be connected

with the earth bar(MEB) which out of the feed-through window.

If needed, DC surge protection circuit could be installed according

to circuit diagram shown in left.
