Cov xob laim tawm tsam kev tiv thaiv kev tiv thaiv hluav taws xob feem ntau yog siv los ntsuas cov khoom siv hluav taws xob hauv qab hluav taws xob (surges) thiab xob laim hauv lub zog hluav taws xob.
Qhov Chaw Surge
1. Lub zog fais fab hloov hloov pauv tuaj yeem faib ua cov khoom pauv tuaj nrog cov haujlwm hauv qab no:
A) Hloov kev ntxhov siab hauv lub zog tseem ceeb, xws li hloov ntawm cov roj capacitorcharch;
b) Kev hloov pauv me me lossis thauj cov kev hloov pauv ntawm cov kab ke faib tawm; C) Resonance tshwm nrog hloov cov cuab yeej xws li cov tub ntxhais thiab cov transists;
D) Ntau cov haujlwm tsis tiav, xws li luv luv hluav taws xob thiab arc ua txhaum ntawm cov khoom siv hluav taws xob thiab cov khoom siv hauv av.
2. Lub ntsiab cai tseem ceeb ntawm kev hloov pauv hluav taws xob tsim hluav taws xob hluav taws xob voltage yog raws li nram no:
a) ncaj qha tawm sab nraud (sab nraum zoov) Circuit Court los ntawm xob laim, txhaj qhov loj tam sim no los ntawm kev tiv thaiv hluav taws xob lossis sab nraud hluav taws xob ua kom tsim hluav taws xob;
b) indirect lighting strikes (piv txwv li xob laim ntawm huab, nyob rau hauv huab, lossis tawm cov tshuab hluav taws xob nyob sab hauv thiab cov tsev sab hauv thiab sab nraud;
C) Lub zog xob laim hluav taws xob tam sim no uas tawm hauv av nyob ze tsim hluav taws xob thaum nws cov khub nrog cov khoom siv hluav taws xob hauv av. Thaum cov xob laim tiv thaiv lub cuab yeej yog qhib kom qhib, lub voltage thiab tam sim no tuaj yeem yauv hloov kho hluav taws xob sai sai, ua rau hluav taws xob cuam tshuam nrog cov cuab yeej nyob ze.
EMCSOSIN SELF -}}}}} Surge Privator xws li ntau cov khoom tiv thaiv (SPDS) thiab kev sib txuas lus cov khoom lag luam. Cov cuab yeej tuaj yeem ua tiav qhov tseeb ntawm IEC 61000-4-5, GB / T 17626.5, Gr-1089-Core Tub Ntxhais thiab lwm yam qauv.
