Angakanani amathuba okuba i-transformer enomsinga ophantsi ingaphumeleli?
Amathuba okungaphumeleli ayahluka ngokwendawo.
Sebenzisa i-multimeter ukulinganisa umgangatho we-transformer esetyenziswa rhoqo
1. Ukuchonga ngqo ngezixhobo zombane
Ezinye ii-multimeter zedijithali zinomsebenzi wokulinganisa i-capacitance, kwaye uluhlu lwazo lokulinganisa yi-2000p, 20n, 200n kunye ne-2 μ kunye ne-20 μ yegiya yesihlanu. Ngexesha lokulinganisa, iiphini ezimbini ze-capacitor ekhutshiweyo zingafakwa ngqo kwi-Cx jack kwibhodi yemitha. Emva kokukhetha uluhlu olufanelekileyo, idatha yokubonisa inokufundwa kwaye i-transformer inokuvavanywa.
2. Fumanisa ngezixhobo zokuxhathisa
Inkqubo yokutshaja ye-capacitor inokubonwa nge-digital multimeter, ebonisa utshintsho lwe-voltage yokutshaja ngobuninzi bedijithali obuhlukeneyo. Ukuba izinga lokulinganisa le-digital multimeter li-n times/second, ngoko ngexesha lokujongwa kwenkqubo yokutshaja ye-capacitor, ukufundwa kwe-n okuzimeleyo nokwanda ngokulandelelanayo kunokubonwa rhoqo ngomzuzwana. Ngokwale mpawu yokubonisa ye-digital multimeter, umgangatho we-capacitor unokubonwa kwaye i-capacitance inokuqikelelwa.
Qaphela: Umgaqo kunye nendlela yokuchonga ziyafana kwi-transformer ene-frequency ephezulu kunye ne-transformer ene-frequency ephantsi.
Ukugcinwa Kwempazamo Kwesiguquli Esiphantsi Sokuguquguquka
Uhlu kunye nezizathu zeempazamo eziqhelekileyo kwiitransformer
(1) Iingxaki ezikhoyo xa i-transformer iziswa. Ezifana neziphelo ezikhululekileyo, iibhloko ze-cushion ezikhululekileyo, ukuwelda okungekho semgangathweni, ukugquma okuphantsi kombindi, amandla angonelanga ombane omfutshane, njl.njl.
(2) Ukuphazamiseka komgca. Ukuphazamiseka komgca yeyona nto ibalulekileyo kuzo zonke izinto ezibangela iingozi zetransformer. Ibandakanya ikakhulu: i-over voltage eveliswa ngexesha lokuvala, i-voltage peak kwinqanaba lomthwalo ophantsi, i-line fault, i-flash over kunye nezinye izinto ezingaqhelekanga. Olu hlobo lwe-fault luthatha indawo enkulu kwiimpazamo zetransformer. Ke ngoko, uvavanyo lokukhusela i-impulse kufuneka lwenziwe rhoqo kwitransformer ukuze kubonwe amandla etransformer ngokuchasene nomsinga wokungena.
(3) Isantya sokuguga kwe-insulation ye-transformer esibangelwa kukusetyenziswa ngendlela engafanelekanga siyakhawuleziswa. Ubomi obuqhelekileyo benkonzo yee-transformer eziqhelekileyo yiminyaka eli-17.8 kuphela, nto leyo engaphantsi kakhulu kunobomi benkonzo obulindelekileyo beminyaka engama-35-40.
(4) I-voltage engaphezulu ebangelwa kukubetha kombane.
(5) Ukugqithisa. Ukugqithisa kubhekisa kwi-transformer ekwimeko yokusebenza yokudlula amandla e-nameplate ixesha elide. Ukugqithisa kudla ngokuvela xa isityalo samandla siqhubeka nokunyusa umthwalo kancinci, isixhobo sokupholisa sisebenza ngendlela engaqhelekanga, isiphene sangaphakathi se-transformer, njl.njl., kwaye ekugqibeleni sibangela ukuba i-transformer igqithise kakhulu. Ubushushu obugqithisileyo obuvelayo buya kukhokelela ekwaluphaleni kwangaphambili kwe-insulation. Xa ikhadibhodi yokukhusela ye-transformer iguga, amandla ephepha aya kuncipha. Ke ngoko, impembelelo yeziphene zangaphandle inokukhokelela kumonakalo we-insulation, onokubangela iziphene.
(6) Ukufuma: ukuba kukho izikhukula, ukuvuza kwemibhobho, ukuvuza kwesigqubuthelo sentloko, ukungena kwamanzi kwitanki yeoyile ecaleni kwesingxobo okanye izixhobo, kwaye kukho amanzi kwioyile yokukhusela, njl.njl.
(7) Ukugcinwa kakuhle akuzange kwenziwe.
