Isebenza njani iKhabhinethi yoLawulo?

Ikhabhinethi yolawulo idibanisa amacandelo ombane angundoqo afana ne-circuit breakers ({0}}okufutshane{0}}ukhuseleko lwesekethe), abafowunelwa, ii-relays, kunye ne-PLC (Programmable Logic Controller) ukufezekisa ulawulo lwezixhobo ezizenzekelayo. Inkqubo isebenza ngolu hlobo lulandelayo: Umsebenzi ufaka imiyalelo ngamaqhosha okanye isikrini sokuchukumisa. Le miqondiso igqithiselwa kwii-activators ngokusebenzisa iireyiyidi (ezilawula ukuvulwa nokuvalwa kwabafowunelwa) okanye ii-PLCs (eziqhuba imiqondiso ngokwengqiqo{3} ecwangcisiweyo). Ukuba ulungelelwaniso lwesantya luyafuneka, i-PLC ithumela imiyalelo kwi-converter frequency, elungelelanisa i-motor's output frequency (umzekelo, 0-50Hz). Abenzi boluvo bajonga iiparamitha ezinje ngoku, amandla ombane kunye nobushushu ngexesha lokwenyani (ngokuchaneka kwe-±1%). Izinto ezingaqhelekanga zibangela iihambo ze-circuit breaker okanye i-alamu ukuqinisekisa ukhuseleko lwezixhobo. Usetyenziso oluqhelekileyo luquka usetyenziso oluzenzekelayo lomgca kunye namandla{13}}ukugcina iisistim zokuqhuba eziguquguqukayo kwiimpompo zamanzi (ukugcina i-20-30%).
