Cov kev ntsuam xyuas rwb thaiv tsev hauv qab no yog ua kom tau raws li qhov kev xav tau ntawm lub zog hluav taws xob transformer.
Tshwj tsis yog tias tus neeg siv tau thov, cov kev sim hauv qab no tau ua raws li hauv qab no (IEC 60076-3):
Hloov impulse xeem: kom paub meej tias cov rwb thaiv tsev ntawm lub transformer terminals thiab windings mus rau lub earthed qhov chaw thiab lwm yam windings, thiab kom paub meej tias lub rwb thaiv tsev lub zog nyob rau hauv lub windings thiab los ntawm lub windings.
Lightning impulse test: kom paub meej tias lub zog hluav taws xob rwb thaiv tsev nyob rau hauv cov ntaub ntawv ntawm xob laim ntaus cov terminals
Sib cais qhov AC tiv thaiv qhov ntsuas hluav taws xob: kom paub meej tias lub zog rwb thaiv tsev ntawm cov kab hloov pauv thiab nruab nrab kev sib txuas terminals thiab cov windings txuas rau lub ntiaj teb thiab lwm yam windings.
Induced AC voltage test (lub sij hawm luv luv ACSD thiab ntev ntev ACLD): kom paub meej tias lub zog rwb thaiv tsev ntawm lub transformer kev twb kev txuas terminals thiab cov windings txuas mus rau earthed qhov chaw thiab lwm yam windings, ob qho tib si ntawm cov theem thiab los ntawm winding.
Kev ntsuas qhov tso tawm ib nrab: kom paub meej tias "ib nrab paug hauv qab qhov kev txiav txim siab ntawm cov khoom siv hluav taws xob hluav taws xob hauv kev ua haujlwm.
Yuav kom simulate lub xob laim impulse voltage thov ntawm lub transformer. Huayi lub tuam txhab hluav taws xob hluav taws xob ua rau lub tshuab hluav taws xob hluav taws xob ntsuas hluav taws xob, uas yog qhov tsim nyog rau lub zog tag nrho yoj tiv taus qhov ntsuas hluav taws xob ntawm 110kV thiab qis dua cov khoom siv hluav taws xob, thiab tseem tuaj yeem siv rau kev sim impulse ntawm lwm yam khoom. Nws txais PLC thev naus laus zis thiab siv ob-core optical fiber ntau los xa cov lus tswj hwm thiab cov khoom siv tawm tswv yim, yog li tsis txhob cuam tshuam electromagnetic thiab txhim kho kev nyab xeeb ntawm kev tswj hwm thiab khoos phis tawj. Cov kev tswj hwm muaj cov phau ntawv, tsis siv neeg tag nrho, thiab cov haujlwm tswj kev ua haujlwm, thiab cov haujlwm ntawm txhua qib yog tus kheej kheej los xyuas kom meej qhov kev ntseeg tau ntawm lub kaw lus. Nws siv txoj kev tswj hwm qhov hluav taws xob thyristor thiab muaj qhov ntsuas qhov ntsuas qhov ntsuas hluav taws xob. Qhov kev ncua deb ntawm qhov chaw nres tsheb pob thiab kev cuam tshuam lub pob sib txawv tuaj yeem hloov kho manually los yog cia li ua kom pom tseeb thiab muab tso rau ntawm LCD vaj huam sib luag.
