Ukunikezwa kwamandla kwe-Sine wave inverter

1. Izici eziyinhloko zokunikezwa kwamandla kwe-sine wave inverter
■ Ukusebenzisa ukulawula kwe-CPU, isifunda silula futhi sithembekile;
■ Ngokusebenzisa ubuchwepheshe bokuguquguquka kobubanzi be-pulse ye-SPWM, okokufaka kuyigagasi le-sine elihlanzekile elinefrikhwensi ezinzile nokulawulwa kwamandla kagesi, elihlunga umsindo nokuhlanekezela okuphansi;
■ Iswishi ye-bypass eyakhelwe ngaphakathi, ukushintsha ngokushesha phakathi kwamapayipi amakhulu ne-inverter;
■ Uhlobo lokuphakelwa kwamandla amakhulu kanye nohlobo lokuphakelwa okuyinhloko kwebhethri:
A) Uhlobo lokuphakelwa kwamandla kagesi: uma kukhona amandla ama-mains, aphuma kuma-mains, futhi ashintshela ngokuzenzakalelayo ekuphumeni kwe-inverter lapho okokufaka kwama-mains kwehluleka;
B) Uhlobo lokuphakelwa kwebhethri eliyinhloko: Ukukhishwa kwe-inverter uma kunamandla amapayipi amakhulu, okuzenzakalelayo lapho okokufaka kwe-DC kwehluleka
■ shintshela ekuphumeni kwamapayipi amakhulu;
Kuvunyelwe ukunqamula i-DC esimweni sokusebenza kwamandla, bese ushintsha ngokuzenzakalelayo ku-bypass ye-mains, ngaphandle kokuthinta ukunikezwa kwamandla komthwalo, futhi kulula ukunakekela nokufaka esikhundleni sebhethri;
■ Uma i-voltage yebhethri iphezulu kakhulu noma iphansi kakhulu, i-inverter power supply izovala okukhiphayo.Uma i-voltage yebhethri ibuyela kokujwayelekile, ukunikezwa kwamandla kuzophuma ngokuzenzakalelayo;
■ Uma umthwalo ugcwele kakhulu, ukunikezwa kwamandla kwe-inverter kuzovala okukhiphayo.Ngemva kwamasekhondi angu-50 wokuqeda ukugcwala, ukunikezwa kwamandla kuzoqalisa kabusha ngokuzenzakalelayo okukhiphayo.Lo msebenzi ulungele ikakhulukazi iziteshi zokuxhumana ezingagadiwe;
■ Umsebenzi wokuxhumana wokusekela, hlinzeka nge-RS232 interface (PIN2, 3, 5), sebenzisa isofthiwe yokuqapha ukuze uqonde isimo sokusebenza sokuphakelwa kwamandla ngesikhathi sangempela;(Qaphela: amamodeli angu-500VA kulolu chungechunge awanawo lo msebenzi okwamanje)
■Nikeza amasethi amabili wamanodi omile angenzi lutho wephutha le-DC input (RS232PIN6, 7) kanye ne-alamu yephutha ephumayo ye-AC (RS232PIN8, 9)
■Isekela umsebenzi wokuvula amandla we-no-DC, futhi ingasebenza ngamandla amapayipi amakhulu kuphela.Lo msebenzi uvumela ugesi oguquguqukayo ukuthi usetshenziswe kuqala, bese ibhethri lifakwa.(Qaphela: amamodeli angu-500VA kulolu chungechunge awanawo lo msebenzi okwamanje)
