Izinkinga zobuchwepheshe ezijwayelekile zomhloli wamanje we-transformer

I-Current Transformer Characteristic Comprehensive Tester, eyaziwa nangokuthi i-CT/PT Analyzer, iyithuluzi lokuhlola elisebenza ezindaweni eziningi eliklanyelwe ngokukhethekile ukuhlolwa kochwepheshe bokuvikela ukudluliselwa kwezici zamanje ze-transformer volt-ampere, ukuhlolwa kwesilinganiso sokuguqulwa kanye nokubandlululwa kwe-polarity.Ingasetshenziswa futhi njenge-transformer.Ithuluzi lokulinganisa lokuhlolwa kokubandlululwa kwe-polarity.Ngezici zesisindo esilula, ukusebenza okulula nokusebenza okuhle kakhulu, kungumkhiqizo ongabizi kakhulu.

Eqinisweni, ukunemba komhloli we-transformer akuyona inkomba ebalulekile yethuluzi.Emithethweni yokuqinisekisa i-transformer, kuyadingeka ukuthi iphutha lokuhlola elibangelwa yisifunda sonke akufanele lidlule i-20% yezinga le-transformer elihloliwe.Idatha ethulwa emsebenzini kufanele ibe yiqiniso.

Izinkinga zobuchwepheshe ezijwayelekile ngesikhathi sokuhlolwa:

1. Ukusebenza kwesihlungi esikhetha imvamisa

Ukuqinisekiswa kwe-Transformer isilinganiso segagasi eliyisisekelo.Njengoba amagagasi amanje ajwayelekile esibili kanye nephutha lesibili nelesithathu le-waveform yamanje ye-transformer ngaphansi kokuhlolwa ahlanekezelwa kakhulu futhi alungiswa ngokuphazanyiswa kwe-high-frequency, umhloli kufanele abe nokukhetha okuhle kwefrikhwensi.Hlunga ukusebenza, hlukanisa okuyisisekelo, futhi wenze izilinganiso.Izici ezibangela ukuhlanekezela ziyinkimbinkimbi kakhulu.Esivivinyweni sokunemba okuphansi (okungaphansi kuka-0.5) kwe-transformer ngaphandle kwesinxephezelo sensimbi egcwele, ukuhlanekezela okuvamile kumayelana ne-10%, futhi ithonya alibonakali.Izinga likazwelonke lidinga ukuncishiswa kwe-harmonic komhloli kube ngaphezu kuka-32dB, okwanele ukusetshenziswa.Kodwa-ke, lapho kuhlolwa ama-transformer anembayo ephezulu noma ama-transformers ane-saturated iron cores, inkomba iphansi.Asikho isilinganiso sokuqinisekiswa kwasekhaya kwale phrojekthi, futhi abakhiqizi abajwayelekile ngokuvamile abaziniki izinkomba.Uma uthenga ithuluzi elisha, abasebenzisi kufanele baliqhathanise nethuluzi elidala ukuze banqume ukuthi lithembekile yini.

2. Yethula umthwalo futhi ufanise ne-transformer evamile

Umthwalo owengeziwe olethwe umhloli ku-transformer ehloliwe kanye nomthwalo olethwe umhloli ku-transformer ejwayelekile ulawulwa ngokuqinile emithethweni.Ukuqinisekiswa kwe-metrology yasekhaya akuziboni lezi zinkomba, futhi abakhiqizi abaningi abazinikezi izinkomba, kodwa bangesinye sezizathu eziyinhloko zedatha yokuhlola ehlukene yamayunithi ahlukene.

3. Umthwalo womugqa

Lapho wenza umthwalo u-Z, gcina ukumelana no-0.06 ohms ezintanjeni ezixhumayo (ezinye zine-0.05 ohms), ngakho-ke isamba sokuphikiswa kwezintambo ezintathu A, B, no-C esibalweni sidingeka sibe ngu-0.06 ohms ukuze sihlolwe.Lapho uqinisekisa ama-transformers amanje emithwalweni encane elinganiselwe (10VA), ukumelana kwezintambo kunomthelela omkhulu kudatha.

4. Ikhebula eliphansi

Njengoba kuyisilinganiso sefrikhwensi yamandla, inkambu ye-electromagnetic yesikhala namandla antantayo kunomthelela omkhulu esilinganisweni.Ekuhloleni, ucingo oluphansi ludlala indima ebalulekile.Intambo yaphansi kufanele isekelwe ngokufanele ngokwemithethonqubo, okubaluleke kakhulu lapho kuhlolwa ngaphezu kuka-0.05 noma i-voltage ephezulu.Kunconywa ukuthi abasebenzisi kufanele bakhethe isethi ephelele yabakhiqizi bezinto zokusebenza abaneminyaka eminingi yesisekelo somkhakha lapho bethenga amathuluzi, kunokuba abakhiqizi besiqephu esisodwa.Kunomehluko obalulekile phakathi kwalokhu okubili kuthiyori kanye nolwazi lokuhlolwa kwe-transformer.Ukukhetha okulungile kungaqinisekisa ukuthi izinkomba zethuluzi zihlangabezana nezidingo zemithethonqubo.
