A kayan aiki domin yanzu kaya kashe. load canji

Domin lafiya aiki, ciki har da gyara da kuma maye na lantarki da kayan aiki, gyara kewaye rabo a karkashin load, da ikon samar da dole ne a katse. Don yin shi da sauki karkashin load saboda abin da ya faru na lantarki baka da bude lambobi na na'urar. A tsari ya zama mai lafiya, yi amfani da wani kayan aiki na musamman - load canji.

Menene wannan na'urar?

Load canji ne a na'urar amfani da su cire haɗin lamba kungiyar a site wani lantarki kewaye via da inji mataki, sanye take da arcing bẽnãye. The na'urar da aka sanya a babban ƙarfin lantarki da kuma lantarki aiki a karkashin wani irin ƙarfin lantarki na 6 da kuma 10 kilovolts. load canji ne yadu amfani ga ƙarshe kuma farfado da ƙarfin lantarki rarraba substations a birane da yankunan karkara, kazalika da shagunan na Enterprises.

Na'urorin ga sarƙoƙi da kananan igiyoyin

Ba tare da high load canji da ake amfani da manual watsa ba tare da extinguishing inji. Ana amfani da a haihuwarka da low igiyoyin - yawanci a cikin wutar lantarki panel na iyali, ko ofishin gabatarwa. Wani misali na irin wannan na'urorin ne load canza b-32. An tsara aiki a haihuwarka 230-400 V kuma a load halin yanzu na 22 zuwa 100 A. Yana yana da daban-daban polyusatsiyu - 1 zuwa 4 lambobi.
