Iiwindings ze-voltage ephakathi nephantsi

Ikhoyili yetransformer

Izinto zokujika zigqunywe nge-epoxy resin - zilungele okusingqongileyo.

Iiwindings zinamandla aphezulu oomatshini kwaye azikhuphi nxalenye kwaye azitshi.

Iiwindings zenziwe ngee-aluminium okanye ii-copper conductors.

Ziziphi iintlobo ezimbini ze-transformer winding?

Kukho ii-windings ezimbini kwi-transformer ejikelezayo ye-coil ephindwe kabini, nganye ijikeleza kwi-iron core efanayo kwaye iqhagamshelwe ngokutshintshana kwe-magnetic flux. I-voltage enee-turns ezininzi iphezulu, ngelixa i-voltage enee-turns ezimbalwa iphantsi. Ngoko ke, inokuguqula inqanaba elinye le-voltage libe lelinye inqanaba nge-frequency efanayo.

Yintoni umahluko phakathi kwee-transformers ze-voltage ephantsi kunye nee-medium voltage?

Ngokutsho kwe-American National Standard Institute (ANSI), ii-transformers ze-high voltage zinokusingatha ubuncinci be-115000 volts ukuya kubuninzi be-11,00,000 volts; ii-transformers ze-medium voltage zinomthamo olinganiselweyo we-2400 ukuya kwi-69000 volts; kwaye ii-transformers ze-low voltage zinomthamo ophantsi we-240 kunye nomthamo ophezulu we-600.

Ii-Voltage Transformers, ezaziwa ngokuba zii-Potential Transformers, zizixhobo ezinciphisa i-voltage ukusuka kwinqanaba eliphezulu ukuya kwinqanaba elikhuselekileyo okanye elamkelekileyo. Zii-transformers eziqhagamshelwe ngaxeshanye ezinika umthwalo omncinci kumbane.

Kunokwenzeka ukulinganisa ngokuchanekileyo uqhagamshelo lwesibini oludibanisayo kunye nee-voltage transformers kuba zine-voltage ratio echanekileyo kunye nobudlelwane besigaba. I-switchgear kwizikhululo zombane zihlala zikwicala le-voltage ephezulu nephantsi yee-power transformers ezinkulu. Zisetyenziswa kakhulu kwizikhululo zombane, kwimizi-mveliso, nakwiinkampani zombane zemveli. Kukho iintlobo ezintathu zee-voltage transformers:

Iitransformer zevolthi ephezulu

Iitransformer zevolthi ephakathi

Iitransformer zevolthi ephantsi

Iitransformer zeVoltage ephezulu

I-voltage ephezulu, i-voltage ephezulu kakhulu, okanye i-voltage ephezulu kakhulu zinxulunyaniswa nokudluliselwa kwamandla avela kwisikhululo samandla. Ukujija kwe-transformer ye-voltage ephezulu kufuneka kulawulwe kude okanye kubekwe ngesandla ukuze kugcinwe kwaye kuvavanywe ngokufanelekileyo. Zidluliselwa ukuze kwandiswe ukusebenza kakuhle. Ii-transformer ze-voltage ephezulu zinokuxhotyiswa ngee-windings ze-voltage ephezulu, ukuhlukaniswa kwe-voltage ephezulu phakathi kwee-windings, okanye zombini.

IiTransformers zeVoltage ephakathi

I-voltage ilingana ngokuphambeneyo ne-amperage, ngoko ke xa i-voltage inyuka, i-amperage iyancipha. Ii-transformers ze-medium-voltage zidla amandla amaninzi kunee-transformers ze-low voltage.

Iitransformer zeVoltage ephantsi

Iitransformer ze-voltage ephantsi zine-rectifier enceda ukuguqula i-output yazo ibe yi-Radio Frequency Interference kunye ne-direct current. Kolu hlobo lwe-transformer, umbane uguqula ngokudlulisela i-current ukusuka kwi-seti enye yee-electrical windings ukuya kwenye.

Kwimizi-mveliso emininzi, ii-voltage transformers ziyimfuneko ukuze oomatshini bazo basebenze. ISchneider Electric India ibonelela ngoluhlu olubanzi lwee-voltage transformers eziqhutywa bubuchwepheshe kunye ne-MV switchgear ezinceda ekuthinteleni iingxaki kunye nokukhusela iisekethe zombane. Ngezisombululo zanamhlanje zeSchneider Electric India, guqula amandla akho okulawula amandla ngee-medium power transformers ezintsha. Azibeki emngciphekweni umgangatho kwaye zibonelela ngeemveliso ezithembekileyo.
