Mhinduro dzeInstrument Transformer(CT&PT)

ongorora mabasa akakosha nezve Instrument Transformer(CT&PT)

 

Instrument Transformers ndeyemhando mbiri:

 

1. Yazvino Transformer (kana Series Transformer)

A current transformer(CT) mudziyo unoshandiswa kuyera ikozvino kuyerera nemukondukita. Inoshandiswa apo hukuru hwemagetsi eA AC hunopfuura kukosha kwakachengeteka kwezvino yezviridzwa zvekuyera, kuderedza / kutsika pasi AC ikozvino kubva pamutengo wepamusoro kusvika kune yakaderera kukosha kwekuyera / kudzivirira / kutonga. Iyo yakajairika yechipiri ikozvino ndeye 5 Arms.

 

2. Inogona Transformer (kana voltage Transformer)

voltage Transformer(PT) chishandiso chinoshandiswa kuyera high voltages mumasisitimu emagetsi nemazvo. Yakagadzirirwa kudzika pasi yakakwira voltage mazinga kune akachengeteka uye anogona kuyerwa mazinga. MaPT anoshandura high-voltage masisitimu kuita yakaderera voltage, saka anoenderana nemamita, relay, uye zvimwe midziyo yekuyeresa inoshandiswa mumasisitimu emagetsi. anoshandiswa apo mhepo ye AC circuit inodarika 750 V sezvo zvisingabviri kupa zvakakwana kusungirirwa pazviyereso zvezviridzwa zvemagetsi kupfuura izvi.

Izvo zvakakosha kuti uedze CT uye PT kuve nechokwadi chekuchengetedzwa kwevashandisi nemidziyo. Kana zvishandiso izvi zviine mhosva kana kusashanda nemazvo, zvinogona kuisa njodzi huru kune vanoishandisa kana midziyo yavanenge vakabatana nayo. Kuyedza zvishandiso izvi usati waisirwa kuchabatsira kuona chero hurema kana mamwe matambudziko uye kudzivirira kubva mukukuvadza kwakanyanya.

Kusimbisa chimiro chemuviri uye maitiro emagetsi ezvino transformer yakaiswa mukuiswa. Ita shuwa kuti CT yakabatana kune sisitimu zvakanaka mune zvese zvinhu (yekutanga uye yechipiri).

High voltage test 11. Verifying secondary circuits, terminals, shorting / isolating links by primary jekiseni 12. single point earthing cheki 13. chikamu chiziviso

1. Winding insulation Resistance test 2. Voltage Ratio test by primary injection 3. Phase Angle Error 4. Winding Resistance Measurement 5. Polarity Test 6. Loop Resistance Measurement 7. Muedzo wemutoro 8. Phase Sequence test 9. Fuse Kukundikana macheki 10. Dziviriro pasi 11. Back Energization Test pa rated Voltage kwemaminitsi gumi nemashanu

 

 

CT PT analyzer

Kuti zvizadzise zvinodikanwa zvekuedzwa kwevashandisi, uye kuve nechokwadi chekuchengetedza uye kushanda kwakajairika kweCT PT, HUAYI akagadzira CT PT analyzer, iyo inotora zvakanyanya zano revatengi uye yakadzika dzidziso kudzidza. Isu tinopa mamodheru akasiyana ane misimboti yekushanda akasiyana kuti tigutse zvakasiyana bvunzo zvinodiwa.

 

Muenzaniso: HYCT-100

Inoshandisa-kushanda kwepamusoro-soro kweDSP neARM, tekinoroji yekugadzira yemhando yepamusoro kuti ive nechokwadi chekushanda kwechigadzirwa chakadzikama uye chakavimbika, chakazara-chinoratidzwa, maotomatiki emhando yepamusoro, uye kushanda nesimba kwepamusoro, muchikamu chinotungamira, ndidzo midziyo yehunyanzvi yekuongorora matransformer muindasitiri yemagetsi.

Muenzaniso HYFA akatevedzana:

Inonyanya kushandiswa pakuongorora nzvimbo dzeP-class CT nePT. Zvinhu zvekuyedzwa zvinonyanya zvinosanganisira hunhu hwekunakidzwa, shanduko reshiyo, polarity, Degauss, 5％ uye 10％ kukanganisa curves, chechipiri chedunhu cheki, uye kumira bvunzo yemagetsi frequency alternating yazvino uye yechipiri mutoro.
