Yintoni i-E-shield?
Isikhuselo se-electrostatic ishidi elibhityileyo elingenamagnetic conductive. Ikhaka linokuba lubhedu okanye i-aluminium. Eli phepha lincinci lihamba phakathi kwe-transformer's amajiko-jiko eprayimari nesekondari. Iphepha kwikhoyili nganye lidibanisa kunye nomqhubi omnye odibanisa kwi-chassis ye-transformer.
Zenza ntoni ii-E-shields kwii-transformers?
E-Izikhuselo ziphinda ziqondise iziphazamiso zombane eziyingozi kude ne-transformer's iikhoyili kunye ne-elektroniki ebuthathaka kwiinkqubo zombane. Oku kukhusela i-transformer kunye nenkqubo exhunywe kuyo.
Makhe sijonge oku ngokweenkcukacha ngakumbi siqale ngento ekhusela i-E-shields.
Ukuthotywa
Iisekethe ezininzi zombane zanamhlanje zixhomekeke kwi-spikes ezidlulayo kunye nengxolo yemowudi. Ikhaka le-E elisekelwe phantsi linciphisa (linciphisa) olu kuphazamiseka.
Lo mfanekiso ungasentla ngasekhohlo ubonisa i-voltage spike eqhelekileyo. Olu hlobo lokunyuka okubukhali kumbane wobonelelo luvela kwizixhobo eziqhelekileyo zeofisi ezifana neekhompyutha okanye oomatshini bokufotokopa. Ii-inverters zikwangumthombo oqhelekileyo wee-spikes ezidlulayo. Umfanekiso osekunene ubonisa umzekelo wengxolo yemowudi kwisekethe yombane. Ingxolo yemowudi ixhaphakile kwiisekethe zombane. Iinkqubo ezingasebenzi kakuhle ngeengcingo ezinokukhuselwa kweentambo ezingafanelekanga zihlala zithwaxwa yingxolo yemowudi.
Ngoku makhe sijonge ukuba i-E-shield ijongana njani nolu kuphazamiseka.
Coupling Capacitive
I-E-shield esekelwe phantsi inciphisa ukudityaniswa kwe-capacitive phakathi kwamajiko okuqala kunye nesekondari. Kunokuba udibane nojiko lwesibini, amaqabane aphambili ajijayo kunye ne-E-shield. I-E-shield esekelwe phantsi ibonelela ngendlela ephantsi yokuthintela ukuya emhlabeni. Iziphazamiso zamandla ombane zithunyelwa kude kumjikelo wesibini. Oku kusebenza kwakhona ukusuka kwelinye icala le-transformer (yesibini ukuya kwiprayimari).
Izikhonkwane ezidlulayo kunye nengxolo yemowudi zingonakalisa iziguquli kunye nezinye izixhobo zombane. Isikhuselo se-electrostatic phakathi kombane ophezulu kunye neekhoyili zamandla ombane aphantsi siyayinciphisa imingcipheko enjalo. Ingqwalasela ebalulekileyo xa unikezela ngombane kwizinto zombane ezibuthathaka.
Imizekelo yeeTransformers Ezisebenzisa i-E-shield
ISolar & Wind Transformers
Ukuphazamiseka kwe-Harmonic kunye nokutshintshwa okukhethekileyo kwii-inverters zelanga zidluliselwe kwigridi yoncedo. Olu phazamiseko lwamandla ombane ludala iziphumo ezinjengokuchaphazeleka kwi-HV eyondla igridi. Ii-spikes ze-overvoltage ezidlulayo kwicala le-utility nazo zinokudlula kwi-inverter. Ezi ziganeko ze-overvoltage zingonakalisa i-inverter's amalungu anovakalelo. Izikhuselo ze-E zibonelela ngokhuseleko kuzo zombini i-transformer, igridi, kunye ne-inverter.
Funda ngakumbi malunga nobungakanani be-solar transformer kunye neemfuno zoyilo.
Qhuba ii-Isolation Transformers
Iziguquli zokwahlula zokuqhuba zenzelwe ukumelana nokuphazamiseka kwamandla ombane aphezulu (harmonics). Olo kuphazamiseka kubangelwa zizixhobo ezifana neemoto eziqhuba (okanye iiVFDs). Ngoko ke igama“qhuba”egameni. Ukongeza kwii-harmonics, iimoto zokuqhuba zinokwazisa ezinye iziphazamiso zombane (njengengxolo yemowudi). Kulapho i-E-shield ingena khona. Iziguquli zokwahlula zokuqhuba zibandakanya ubuncinci i-E-shield phakathi kwe-HV kunye neekhoyili ze-LV. Amakhaka amaninzi anokusetyenziswa ngokunjalo. Izikhuselo ze-E zinokubekwa phakathi kweekhoyili zangaphakathi kunye namalungu angundoqo kwakhona.
Usetyenziso olunokuphazamiseka kwamandla ombane (njengezikhonkwane ezidlulayo kunye nengxolo yemowudi) zixhamla kwisiguquli esine-E-shield. Izikhuselo ze-E azibizi, kwaye zinika imbuyekezo ebalulekileyo kutyalo-mali apho imiba yobulunga bamandla isisoyikiso.
