CTs akakosha mune akasiyana maapplication, anosanganisira:
Dziviriro Systems: CTs inosanganisirwa kune inodzivirira relay inochengetedza midziyo yemagetsi kubva pakuremerwa uye mapfupi maseketi. Nekupa shanduro yakadzika-pasi yezvino, vanoita kuti relays dzishande pasina kuratidzwa kumhepo yakakwirira.
Metering: Munzvimbo dzekutengeserana uye dzeindasitiri, maCT anoshandiswa kuyera mashandisirwo emagetsi. Vanobvumira makambani ekushandisa kuti atarise huwandu hwemagetsi anopedzwa nevashandisi vakakura pasina kubatanidza zvakananga michina yekuyeresa kune yakakwira-voltage mitsetse.
Power Quality Monitoring: MaCTs anobatsira mukuongorora simba remagetsi nekuyera maharmonics aripo uye mamwe maparamita anokanganisa kushanda kwemagetsi masisitimu.
Kunzwisisa Voltage Transformers (VT)
A Voltage Transformer(VT), inozivikanwawo sePotential Transformer (PT), yakagadzirirwa kuyera mazinga emagetsi mumasisitimu emagetsi. Kunge maCTs, maVT anoshanda pamusimboti we electromagnetic induction, asi iwo akabatanidzwa mukufambirana nedunhu rine voltage inofanirwa kuyerwa. Iyo VT inodzika pasi yakakwira voltage kusvika yakaderera, inogoneka nhanho inogona kuyerwa zvakachengeteka nezviridzwa zvakajairwa.
VTs inowanzoshandiswa mu:
Voltage Measurement: VTs inopa kwakaringana mavheti ekuverenga ekutarisa uye kutonga zvinangwa muzviteshi uye kugovera network.
Dziviriro Systems: Zvakafanana neCTs, VTs anoshandiswa mukudzivirira relay kuona abnormal voltage mamiriro, akadai overvoltage kana undervoltage, izvo zvinogona kutungamira kukuvara kwemidziyo.
Metering: VTs anoshandiswawo mumagetsi metering application, kunyanya kune yakakwira-voltage masisitimu, inobvumira zvinoshandiswa kuyera mashandisirwo esimba nemazvo.
Misiyano Yakakosha PakatiCTuye vt
Nepo ese maCTs neVTs ari akakosha masystem mumasisitimu emagetsi, anosiyana zvakanyanya mukugadzira kwawo, basa, uye mashandisirwo. Heino misiyano yakakosha:
Kushanda
CTs inoyera ikozvino uye yakabatanidzwa mumutsara nemutoro. Ivo vanopa yakaderedzwa-pasi ikozvino yakaenzana neyekutanga ikozvino.
VTs inoyera voltage uye yakabatanidzwa mukufambirana nedunhu. Vanodzika pasi high voltage kusvika padanho rezasi kuti riyerwe.
Type yekubatanidza:
CTs dzakabatana munhevedzano, zvichireva kuti yese yazvino inoyerera nepakati pekutanga mhepo.
MaVT akabatana achienderana, achibvumira kuti voltage padunhu rekutanga kuyerwa pasina kukanganisa kuyerera kwezvino.
Zvakabuda:
CTs inogadzira chechipiri ikozvino chiri chidimbu chepakutanga ikozvino, kazhinji muhuwandu hwe1A kana 5A.
VTs inogadzira yechipiri voltage inova chidimbu chemagetsi ekutanga, anowanzogadziriswa kusvika ku120V kana 100V.
Applications:
CTs inonyanya kushandiswa kuyerwa kwazvino, kudzivirira, uye metering mune yakakwirira-ikozvino maapplication.
VTs anoshandiswa kuyera voltage, dziviriro, uye metering mune yakakwira-voltage application.
Kufunga Kwekugadzira:
CTs inofanira kugadzirirwa kubata mafungu akakwirira uye inowanzotarwa zvichienderana nemutoro wavo (mutoro wakabatanidzwa kune yechipiri).
MaVTs anofanirwa kugadzirwa kuti akwanise kubata ma voltages akakwira uye akayerwa zvichienderana neiyo voltage shanduko reshiyo.
