Ungashintsha kanjani futhi ulungise i- ukushisa okuphezulu kwesithando sikagesi thyristor?

Ukushintsha Ukuze ungene esikhundleni seyunithi ye-thyristor, qala ngokuhlukanisa isithando somlilo sikagesi esinezinga eliphezulu lokushisa esiphephweni samandla, bese ususa ikhava eseceleni kwesokunxele (0). Rekhoda konke ukuxhumana ku-thyristor, bese uyinqamula. Shintshanisa idivayisi, bese uphinde uxhume kabusha.

Qaphela: Uma ushintsha amandla kagesi angu-208V, udinga ukufaka esikhundleni seyunithi ye-thyristor.

Uma iyunithi ye-thyristor ishintshwa ngenxa yoshintsho lwe-voltage, ukulungiswa okulungile kompompi we-transformer kufanele futhi kusethwe. Ngemva kokushintsha noma iyiphi iyunithi ye-thyristor, noma ngemva kokushintsha i-voltage noma i-transformer tap, i-potentiometer ku-thyristor kufanele ilungiswe ukuze inikeze izingxenye ezifanele zamanje. Lokhu kusebenza kufanele kwenziwe ngabasebenzi abaqeqeshiwe, ngoba ama-voltage ayingozi akhona egumbini lokulawula.

Ukwengeza, i-ammeter yokuqinisa elinganisiwe iyadingeka. Ngaphambi kokuxhuma amandla kagesi, vula i-potentiometer ku-thyristor kwesokunxele (ngokuphambene newashi). Lokhu kusetha okukhiphayo okwamanje kwe-thyristor ukuze “kucime”. Xhuma amandla uma uvala ikhava eseceleni. Qaphela! Setha izinga lokushisa lomlilo libe inani elikhulu. Vumela isitofu siqale ukushisa. Linganisa umsinga ngokusebenzisa isifunda sengxenye. Lapho ukala, sebenzisa ipheya ewugqinsi yamakhebuli ohlangothini lwesobunxele lwe-transformer ukuze usonge i-ammeter ye-clamp. Lungisa i-potentiometer etholakala ebusweni beyunithi ye-thyristor. Kancane kancane lungisa kwesokudla (ngokwewashi) ukuze ukhuphule imanje, bese ume kancane ukuze wenze i-ammeter iphendule.

Qhubeka ulungise ukuze ukufundwa kwe-ammeter kube phakathi kuka-(149 kuya ku-150 A-ye-HTF 17) noma (139 kuya ku-140A-ye-HTF 18). Lokhu kulungiswa kufanele kwenziwe phakathi kwemizuzu yokuqala emi-5 yokushisa, futhi ukuhlolwa kokugcina kufanele kwenziwe lapho izinga lokushisa lesithando somlilo esishisa kakhulu liphansi kunokushisa kwalo okuphezulu cishe ngo-100 ° C. Uma kunesidingo, qhubeka ulungisa ngaphansi kwalesi simo sokushisa. Nqamula ukunikezwa kwamandla futhi uqiniseke ukuthi ushintsha iphaneli eseceleni.
