Mavuto odziwika bwino a Current transformer tester

Current Transformer Characteristic Comprehensive Tester, yomwe imadziwikanso kuti CT/PT Analyzer, ndi chida choyesera chamitundumitundu chomwe chimapangidwa kuti chiyesere akatswiri achitetezo amtundu waposachedwa wa volt-ampere, kuyezetsa chiŵerengero cha kusintha ndi tsankho.Itha kugwiritsidwanso ntchito ngati thiransifoma.Chida choyezera poyesa tsankho la polarity.Ndi mawonekedwe a kulemera kopepuka, ntchito yabwino komanso magwiridwe antchito abwino kwambiri, ndizotsika mtengo.

Ndipotu, kulondola kwa tester transformer si chizindikiro chofunikira cha chida.M'malamulo otsimikizira thiransifoma, pamafunika kuti cholakwika choyesa chomwe chimayambitsidwa ndi dera lonse chisapitirire 20% ya mulingo woyeserera woyeserera.Zomwe zaperekedwa mu ntchitoyi ziyenera kukhala zenizeni.

Mavuto azaumisiri omwe amapezeka nthawi yoyeserera:

1. Pafupipafupi kusankha fyuluta ntchito

Kutsimikizira kwa Transformer ndiko kuyeza kwa mafunde oyambira.Popeza mafunde amtundu wachiwiri wapano komanso achiwiri ndi apamwamba mafunde amtundu wa transformer omwe akuyesedwa amasokonekera kwambiri ndikusinthidwa ndi kusokoneza kwapang'onopang'ono, woyesayo ayenera kukhala ndi masankho abwino pafupipafupi.Zoseferani, patulani zoyambira, ndipo pangani miyeso.Zomwe zimayambitsa kupotoza zimakhala zovuta kwambiri.Mu mayeso otsika (osakwana 0.5) osinthira thiransifoma popanda chipukuta misozi chachitsulo chodzaza, kupotoza kwakukulu kumakhala pafupifupi 10%, ndipo chikokacho sichikuwonekera.Muyezo wa dziko umafuna kuti kuchepetsedwa kwa harmonic kwa tester kupitirira 32dB, yomwe ndi yokwanira kuti igwiritsidwe ntchito.Komabe, poyesa zosinthira zolondola kwambiri kapena zosinthira zokhala ndi zitsulo zachitsulo zodzaza, indexyo imakhala yotsika.Palibe muyeso wotsimikizira zapakhomo za polojekitiyi, ndipo opanga ambiri nthawi zambiri samapereka zizindikiro.Pogula chida chatsopano, ogwiritsa ntchito ayenera kuchiyerekeza ndi chida chakale kuti adziwe ngati chiri chodalirika.

2. Yambitsani katundu ndi machesi ndi thiransifoma wamba

Zowonjezera zowonjezera zomwe zimabweretsedwa ndi tester ku transformer yoyesedwa ndi katundu wobweretsedwa ndi tester ku transformer yokhazikika imayendetsedwa mosamalitsa m'malamulo.Kutsimikizika kwa metrology yapakhomo sikuzindikira zizindikiro izi, ndipo opanga ambiri samapereka zizindikiro, koma ndi chimodzi mwazifukwa zazikulu za data yoyesa yamayunitsi osiyanasiyana.

3. Katundu wa mzere

Mukapanga katundu Z, sungani kukana kwa 0,06 ohms pamawaya olumikizira (ena amakhala ndi 0.05 ohms), kotero kuchuluka kwa kukana kwa mawaya atatu A, B, ndi C pachithunzichi kumafunika kukhala 0,06 ohms poyesa.Potsimikizira zosintha zamakono pazitundu zing'onozing'ono (10VA), kukana kwa mawaya kumakhudza kwambiri deta.

4. Chingwe chapansi

Popeza ndikuyezera pafupipafupi kwamagetsi, gawo la electromagnetic danga ndi kuthekera koyandama kumakhudza kwambiri muyeso.Poyesa, waya wapansi umagwira ntchito yofunikira.Waya wapansi uyenera kukhala wokhazikika molingana ndi malamulo, omwe ndi ofunikira kwambiri pakuyesa pamwamba pa 0.05 kapena voteji yayikulu.Ndibwino kuti ogwiritsa ntchito asankhe gulu lathunthu la opanga zida omwe ali ndi zaka zambiri zamakampani akamagula zida, m'malo mopanga zida zamtundu umodzi.Pali kusiyana kofunikira pakati pa ziwirizi mu chiphunzitso ndi chidziwitso cha kuyesa kwa transformer.Kusankhidwa koyenera kungatsimikizire kuti zizindikiro za chidacho zimakwaniritsa zofunikira za malamulo.
