Kutheni i-AC contactor isenza isandi esirhabaxa?

XaIsixhobo soqhagamshelwano lwe-ACiyasebenza, iya kudibanisa okanye ikhuphe isekethe, ngoko ke izinto ezibangela ukukhutshwa kwe-arc kunye ne-corona ziya kuveliswa kwiikhonkco, nto leyo ebangela ingxolo enkulu.

Xa oonxibelelwano abakwi-AC contactor bedibanisa isekethe, umahluko onokubakho ngenxa yokuxhathisa uya kubangela ukukhupha i-arc phakathi koonxibelelwano. Imeko ye-arc iya kuhlala ixesha elithile kwaye ivelise amaqondo obushushu aphezulu kakhulu kunye nemitha yokukhanya, ngaloo ndlela ivelise ingxolo ethile.

Ukongeza, xa i-arc iphela, intsimi yombane eyenziwe phakathi kwezi zixhobo ayizukunyamalala ngoko nangoko, kodwa iya kuvelisa i-voltage ephezulu ngephanyazo, nto leyo ebangela i-corona discharge. I-corona discharge ikwavelisa isandi.

Ngoko ke, i-AC contactor iya kuvelisa i-arc kunye ne-corona discharge phenomena ngexesha lokusebenza, nto leyo ebangela ukuba kubekho isandi esivakalayo. Esi sandi sidla ngokuba sincinci kakhulu, kodwa sinokuvakala phantsi kweemeko ezithile, njengobusuku obuzolileyo okanye xa i-contactor ifakwe kufutshane nendlebe yakho.
