Ntau tus ncej cog kev tiv thaiv hnyav, tiv thaiv ntaus, tub ceev xwm ntes kaw suav nrog kev daws teeb meem rau kev tiv thaiv tshuab li 440 V ac tiv thaiv kev tiv thaiv vim yog los ntawm cov pa hauv qhov chaw tawm thiab hloov mus ua haujlwm.

Hom 2 / Chav Kawm II

Muaj peev xwm ua kom poob cov hluav taws xob ntxiv (8/20 μs). Haum rau qib thib ob ntawm kev tiv thaiv hauv kev muab cov phiaj hluav taws xob faib rau hauv uas hom 1 tiv thaiv raug ntsia, lossis rau thawj theem kev tiv thaiv rau cov ntawv thov tsis raug ntaus ncaj qha thiab tsis muaj lub teeb thaiv sab nraud thaiv. EN 61643-11 / IEC 61643-11.

LSP yog txoj kab ntawm AC lub zog tiv thaiv hluav taws xob yog tsim los npog tag nrho cov teeb meem hloov mus rau hauv cov hluav taws xob qis. Lawv muaj nyob rau hauv ntau hom ntawv, uas txawv hauv:

- AC Surge Protective Device T2 / Hom 2 / Chav C / Chav II
- AC network configuration (Ib / 3-Theem)
- Kev nqus dej tawm (Iimp, Imax, Hauv)
- Kev tiv thaiv thev naus laus zis (varistors, GDT)
- Nta (plug-in, tej thaj chaw deb teeb liab, kev cog lus me me, tsim qauv rau hauv qhov chaw me me)

Kev ua haujlwm ntau qhov sib txuam ua kom muaj kev tiv thaiv zoo, SPD, cov khoom siv tiv thaiv kev tiv thaiv, kev tiv thaiv khaub thuas ntes SLP40K series yog cov pab pawg hom 2 T2 Chav Kawm C Surges Tiv Thaiv. Lawv npaj los ua ib qho kev tiv thaiv kev tiv thaiv kev hloov mus los ntawm kev hloov pauv ceev nrawm lossis ntaus ncaj qha ntawm xob laim ntaus cov hluav taws xob (cov khoom seem).

Nws raug nquahu kom nruab Chav Kawm II SPDs txhua 10 - 20 metres ntawm cable ntev repetitively, feem ntau mus rau lub ntsiab thiab xa tawm cov laug cam. Lub SLP40K-440 tau tsim los rau kev sib koom tes ncaj qha nrog Chav I SPDs ntawm kab FLP25. Nyob rau hauv cov ntaub ntawv ntawm SLP40K-275, qhov ua kom sib haum nrog txoj kab FLP25 yog ua los ntawm txoj kev 10 m cable ntev.

Tus tsim ntawm AC Surge Protective Device T2 yog ua raws Hlau Hlau Oxide Varistors. Xws li tus tsim muab lub sijhawm teb tau tsawg heev. Tus qauv tsim nrog plug-in inserts tso cai rau kev hloov pauv yooj yim thiab ceev ceev ntawm kev ua haujlwm modules nyob rau hauv cov ntaub ntawv ntawm MOV yog dhau yog tias nws lub neej vim feem ntau tshwm sim ntawm overvoltage cov dhau los.
