Kungani i-AC contactor yenza umsindo wokubhonga?

LaphoI-contactor ye-ACiyasebenza, izoxhuma noma inqamule isekethe, ngakho-ke kuzokhiqizwa izimo zokukhishwa kwe-arc kanye ne-corona koxhumana nabo, okuholela ekuqhumeni komsindo.

Uma oxhumana nabo ku-contactor ye-AC bexhuma isekethe, umehluko ongaba khona ngenxa yokumelana uzobangela ukukhishwa kwe-arc phakathi koxhumana nabo. Isenzakalo se-arc sizohlala isikhathi esithile futhi sikhiqize amazinga okushisa aphezulu kakhulu kanye nemisebe yokukhanya, ngaleyo ndlela sikhiqize inani elithile lomsindo.

Ngaphezu kwalokho, lapho i-arc inyamalala, insimu kagesi eyakhiwe phakathi koxhumana nabo ngeke inyamalale ngokushesha, kodwa izokhiqiza i-voltage ephezulu ngokushesha, okubangela isenzakalo sokukhishwa kwe-corona. Isenzakalo sokukhishwa kwe-corona siphinde sikhiqize umsindo.

Ngakho-ke, i-AC contactor izokhiqiza izenzakalo zokukhishwa kwe-arc kanye ne-corona ngesikhathi sokusebenza, okuholela ekukhiqizweni komsindo ovunguzayo. Lo msindo uvame ukuba mfushane kakhulu, kodwa ungase uzwakale ngaphansi kwezimo ezithile, njengobusuku obuthule noma lapho i-contactor ifakiwe eduze kwendlebe yakho.
