1, Isingeniso
Ikhabhinethi yokushintsha iwuhlobo lwemishini kagesi.Imigqa yangaphandle yekhabhinethi yokushintsha ifaka inkinobho yokulawula eyinhloko kukhabhinethi kuqala, bese ufaka inkinobho yokulawula encane.Igatsha ngalinye libekwe ngokwezidingo zalo.Isibonelo, amathuluzi, isilawuli esizenzakalelayo, amaswishi kazibuthe enjini, izixhumi ezihlukahlukene ze-AC, njll. Ezinye zifakwe negumbi lamandla kagesi aphezulu kanye namakhabethe okushintsha egumbi lamandla kagesi aphansi, amabhasi anamandla kagesi, njengezitshalo zikagesi, njll., nokunye. aphinde afakwe ngokuchithwa komjikelezo ophansi wemishini emikhulu.
Ikhabhinethi yokushintsha inemisebenzi yelayini engenayo nephumayo ephezulu, izintambo ezingenayo neziphumayo, izintambo zokuxhuma amabhasi, njll. Isebenza kakhulu ezindaweni ezihlukahlukene ezifana nezimboni zamandla kagesi, iziteshi ezincane, i-petrochemical, i-metallurgical steel rolling, imboni ekhanyayo nezindwangu, izimboni. kanye namabhizinisi ezimayini, izindawo zokuhlala, izakhiwo eziphakeme, njll.
2. Imodeli yomkhiqizo
I-switchgear izohlangabezana nezidingo ezifanele ze-"Standard for AC Metal Enclosed Switchgear", equkethe izingxenye ezimbili ezinkulu: umzimba wekhabhinethi kanye ne-circuit breaker.Umzimba wekhabhinethi uqukethe igobolondo, izingxenye zikagesi (kuhlanganise nezingxenye zokuvikela), izindlela ezihlukahlukene, amatheminali esibili kanye nezintambo.
I-KYN series medium voltage switchgear iyisizukulwane esisha se-switchgear esakhiwe yi-JONCHN Group ngokwezimo zikazwelonke zase-China ngesisekelo sokwethulwa kobuchwepheshe obuthuthukisiwe obuvela kwa-Areva.
