Ukwenzela ukuthintela ingxaki yokuvuza, ukongeza kwisiseko seshaja imfumba, Ukukhetha umkhuseli wokuvuza nako kubaluleke kakhulu. Ngokwe-GB / T 187487.1, umkhuseli wokuvuza wemfumba eshaja kufuneka asebenzise uhlobo b okanye uhlobo olukhuselekileyo ngokuchasene nokuvuza kwe-AC, kodwa kukhusela ngokuchasene ne-DC ye-AC. Umahluko omkhulu phakathi kohlobo B kunye nohlobo olo lolo hlobo l ukukhuselwa kwi-DC ukuvuza. Nangona kunjalo, ngenxa yobunzima kunye nokunqongophala kweendleko zohlobo lwe-CEBISO LWE-CEBT, uninzi lwabavelisi Okwangoku khetha uhlobo A. Eyona ndlela inkulu yohlobo lwe-DC ayisiyo ukwenzakala komntu, Kungatsho ukuba ukhuseleko lwangoku lokukhusela iipiles lunengozi ezifihlakeleyo kwinqanaba eliqhelekileyo.
Chwetheza umphunga wesekethe
Umphunga wesekethe wekhompyutha kunye nohlobo lwesekethe i-ac acking ngokusisiseko ngokwemigaqo yomgaqo-nkqubo (ixabiso lokuvuza lilinganiswa ngokulandelelana kwe-zero), kodwa iimpawu ze-magnetic ziphuculwe. Iqinisekisa ukuhamba phantsi kwezi meko zilandelayo:
(a) okufanayo njengohlobo lwe-AC.
(b) Intsalela isusa i-DC yangoku.
.
Chwetheza i-blow b breaker wesekethe-(I-Chinaevse inokwenza uhlobo lwe-rcd b)
Uhlobo lwesekethe lwe-B lokuvuza lunokukhusela ngokuthembekileyo imiqondiso ye-ACSOID, itsala imiqondiso ye-DC kunye nemiqondiso egudileyo, kwaye inezifuno zoyilo eziphezulu kunohlobo lokutshabalalisa iisekethe. Iqinisekisa ukuhamba phantsi kwezi meko zilandelayo:
a) ngokufanayo nohlobo A.
b) I-SINUSOIDS SINUSUSOIDAL YOKUGQIBELA I-1000 Hz.
c) I-AC i-AC yangoku idluliselwe nge-DC egudileyo ye-0.4 times times olwenziweyo
d) Ukudodobala kwentsalela i-DC yangoku kusetyenziswa ngamaxesha angama-0.4 ukhangelwe intsalela yentsalela okanye i-DC egudileyo ye-DC ye-10ma ye-10MA (nayiphi na into enkulu).
e) Imijikelezo ye-DC ye-DC eyenziwe zezi zisekethe zilandelayo:
-Iziqingatha zoqhagamshelo zebhulorho ze-bridge ye-bridge
- I-3-Pole kunye ne-4-pole yomhlaba ivuza iSekethe, i-3 isiqingatha se-3 isiqingatha senkanyezi okanye i-6 yesiqingatha sebhulorho.
