Hitamo insinga ukurikije agaciro kemewe k'ubushobozi bwo gutwara bwa none

Igice cyambukiranya insinga cyimbere mu nzu kigomba gutoranywa ukurikije ubushobozi bwemewe bwo gutwara insinga, agaciro kemewe gutakaza umurongo wumurongo, nimbaraga za mashini zinsinga.Mubisanzwe, insinga zitwara ubuso zatoranijwe ukurikije ubushobozi bwemewe bwo gutwara, hanyuma igenzura rigakorwa ukurikije ibindi bihe.Niba igice cyambukiranya kitujuje ibyangombwa bisabwa kugirango habeho kalibrasi, umuyobozi agomba gutoranywa hakurikijwe byibuze byemewe byambukiranya bidashobora kubahiriza ibisabwa.

Ampacity wire yemewe: Ampacity yemewe ya wire nayo yitwa ampacity umutekano cyangwa agaciro keza ka wire.Ubushyuhe ntarengwa bwemewe bwo gukora bwinsinga rusange ni 65 ° C.Niba ubushyuhe burenze ubu bushyuhe, urwego rwo kubika insinga ruzasaza vuba, rwangirika kandi rwangiritse, ndetse rushobora no guteza umuriro.Ibyo bita ubushobozi bwemewe bwo gutwara insinga nigiciro ntarengwa gishobora gutambuka igihe kirekire mugihe ubushyuhe bwakazi butarenze 65 ° C.

Kubera ko ubushyuhe bwakazi bwinsinga butajyanye gusa numuyoboro unyura murugozi, ahubwo bifitanye isano nuburyo bwo gukwirakwiza ubushyuhe bwinsinga hamwe nubushyuhe bwibidukikije, ubushobozi bwemewe bwo gutwara insinga ntabwo ari agaciro keza.Iyo insinga imwe ikoresha uburyo butandukanye bwo gushiraho (uburyo butandukanye bwo gushyira, uburyo bwo gukwirakwiza ubushyuhe nabwo buratandukanye) cyangwa mubushyuhe butandukanye bwibidukikije, ubushobozi bwayo bwo gutwara ibintu nabwo buratandukanye.Reba ku mfashanyigisho ya mashanyarazi kubushobozi bwemewe bwo gutwara insinga hamwe nuburyo butandukanye bwo gushiraho.

Ibiriho kumurongo umutwaro urashobora kubarwa nuburyo bukurikira:

Icyiciro kimwe cyiza cyo kurwanya inzitizi: I = P / U.

Inzira imwe yumuzingi hamwe na inductance: I = P / Ucosφ

Ibyiciro bitatu byuzuye birwanya inzitizi: I = P / √3UL

Ibyiciro bitatu byumuzingi hamwe na inductance: I = P / √3ULcosφ

Ibisobanuro byibipimo muburyo bwavuzwe haruguru ni:

P: ni imbaraga z'umutwaro, muri watts (W);

UL: ni voltage yumuriro wibyiciro bitatu, muri volt (V);

cosφ: ni ibintu bitera imbaraga.

Iyo uhisemo ukurikije ubushobozi bwemewe bwo gutwara insinga, ihame rusange nuko ubushobozi bwemewe bwo gutwara butari munsi yumubare wabazwe kumurongo ugizwe.
