Wararka - Waa maxay PT/CT?

PTWaxaa caadi ahaan loo yaqaan transformer danab warshadaha korontada iyo CT waa magaca guud ee transformer-ka hadda ee warshadaha korontada.

Voltage Transformer (PT): waa qalabka korantada ee beddela tamarta sare ee nidaamka korantada oo u beddela tamar hoose oo gaar ah (100V ama 100 / √ 3V).

Transformer-ka suurtagalka ah (PT, VT) wuxuu la mid yahay Transformer, kaas oo loo isticmaalo in lagu beddelo korantada khadka.Si kastaba ha ahaatee, ujeedada sababta transformerku u beddelo danab waa in la gudbiyo tamarta korontada.Awoodu waa mid aad u weyn, guud ahaan kilovolt ampere ama megavolt ampere sida unugga xisaabinta.Ujeedada sababta Transformer-ka danabku u beddelo danab waxaa inta badan loo isticmaalaa in lagu cabbiro mitirka iyo sahayda korantada iyadoo la adeegsanayo aaladaha ilaalinta gudbinta, cabbira tamarta, tamarta iyo tamarta khadka, ama si loo ilaaliyo qalabka qiimaha leh ee khadka marka uu xariiqdu xumaado Sidaa darteed, awoodda Transformer waa mid aad u yar, guud ahaan kaliya dhowr ampere volt, daraasiin ampere volt, iyo ugu badnaan ma aha in ka badan kun kun volt ampere.

Transformer-ka hadda (CT): waa qalabka koronto ee beddela hadda ku jira nidaamka danabka sare ama hadda weyn ee nidaamka danab yar oo heer gaar ah oo hadda yar (5a ama 1a).

Transformer-ka hadda jira waa qalab u beddelaya hadda weyn ee dhinaca aasaasiga ah una beddelaya hadda yar oo dhinaca sare ah iyadoo loo eegayo mabda'a soo-saarka korantada.Transformer-ka hadda wuxuu ka kooban yahay xudunta xiran iyo dabaylaha.Wareegeeda hore ee dabaysha aad bay u yartahay, waxayna si taxane ah ugu xidhan tahay wareegga kaas oo u baahan in la cabbiro wakhtiga hadda jira.Sidaa darteed, waxay inta badan haysataa dhammaan qulqulka qulqulaya iyada oo loo marayo khadka, iyo wareegyada labaad ee wareega ayaa ka badan.Waxay si taxane ah ugu xidhan tahay aaladda cabbiraadda iyo wareegga ilaalinta.Marka transformer-ka hadda uu shaqeynayo, wareeggiisa labaad mar walba waa la xiraa, sidaas darteed xannibaadda xirmooyinka taxanaha ah ee qalabka cabbirka iyo wareegga ilaalinta waa mid aad u yar, iyo xaaladda shaqada ee qalabka hadda jira waxay ku dhowdahay wareegga gaaban.Transformer-ka hadda jira wuxuu u beddelaa hadda weyn ee dhinaca hore u beddelaya hadda yar ee dhinaca sare si loo cabbiro, dhinaca labaadna lama furi karo wareegga.
