Ukuphendula kwisicelo kunye nentsingiselo yophuhliso lwezicelo zobuchwephesha obutsha kuthutho lukaloliwe, abanini babahlali baseTshayina sele beqwalasele indlela yokwenza indlela entsha yokusebenza ngobukrelekrele kunye nokugcinwa komgaqo kaloliwe ukuqinisekisa ukhuseleko, uhlaza, ukuthembeka, ukusebenza ngokufanelekileyo, kunye nokuphantsi. -iindleko zokusebenza kwezithuthi zikawonke-wonke ezidolophini.
Umbane kaloliwe ohamba ngesantya esiphezulu: usebenzisa amandla ombane wenkqubo yonikezelo lwamandla, uguqula amandla ombane abe ngamandla ombane ekinetic, kwaye ugcine i-offset.Inkqubo yombane wokukhanyisa umbane inikeza amandla ombane ohlukeneyo, i-escalators, i-blower, iimpompo kunye nezinye izixhobo zoomatshini bamandla kwizikhululo kunye namacandelo, kunye namandla okunxibelelana, umqondiso, ukuzenzekelayo kunye nezinye izixhobo.Ukunikezelwa kwamandla okutshintsha kwenkqubo yokukhanyisa ubunjineli bamandla kubandakanya isikhululo sokuhambisa uxinzelelo lwegazi kunye nezibane zokukhanyisa ubunjineli bamandla kunye nezixhobo zokuhambisa izibane.
Inkqubo yonikezelo lwamandla echaziweyo ichazwe ngokweenkcukacha kwimbono yendawo yangaphakathi, apho izixhobo ezininzi zokubonelela ngombane zifumaneka phantsi kwesikhululo ngasinye sokuhambisa.I-AC kunye ne-DC inokohlula izixhobo zonikezelo lwamandla zibe yinkqubo ye-AC kunye nenkqubo ye-DC.
IiHarmonics kuloliwe wasezidolophini ubukhulu becala zivela kwiyunithi yokutshintsha umbane webhanti yokutsala, ilandelwa yisethi epheleleyo yeeyunithi zobonelelo lwamandla eDC, izibane, izinyusi, iimonitha, izilungisi zomoya, imibhobho yokuhambisa amanzi kunye nezinye izixhobo.I-harmonics ephambili yi-harmonics ye-5, ye-7, ye-11 kunye neye-13, kunye nezinye ii-harmonics ze-3 nazo zibandakanyiwe.Oovimba abangasebenziyo kwinkqubo yokusetyenziswa kwe-harmonic ephezulu yonyusa ilahleko yomgca, ichaphazela ukusebenza okuthembekileyo kokhuseleko lombane kunye nolawulo oluzenzekelayo, kunye nokunciphisa ukhuseleko lokusebenza lwezixhobo zombane ezisetyenzisiweyo, ngaloo ndlela zivelisa ukuphazamiseka kwe-electromagnetic kunxibelelwano kunye nemiqondiso.I-Harmonics inokuba nempembelelo eyonakalisayo kwezinye izixhobo zembuyekezo yamandla asebenzayo kumgca.Ngelo xesha, isixhobo sokubuyisela amandla asebenzayo siya kukhulisa i-harmonics, yenze isangqa esibi.
Ixabiso lomsebenzisi woLawulo lweHarmonic
Umzila kaloliwe wasezidolophini, ingakumbi unikezelo lombane kunye nenkqubo yokuhanjiswa kwezikhululo zikaloliwe ohamba ngaphantsi komhlaba, ufuna ukuthembeka okungqongqo kakhulu konikezelo lwamandla.I-Pulse current yiyona nto ibangela ukuba isongelo lithembeke kumandla ayo.Ukusetyenziswa kwezihluzi ezisebenzayo kunokulawula ngokufanelekileyo i-harmonics, ukunciphisa ingozi ye-harmonics kubonelelo lwamandla kunye neenkqubo zokusasaza, kunye nokuqinisekisa ukusebenza okukhuselekileyo nokuzinza komzila kaloliwe wasezidolophini.Ngelo xesha, emva kokucoca i-harmonic, ukulahlekelwa kwe-harmonic kwenkqubo kuncitshisiwe, kwaye ifowuni yembuyekezo ye-capacitor yasekuqaleni ingasetyenziselwa ngokuqhelekileyo, ukunciphisa ngakumbi ukulahleka kwenkqubo.
Iingxaki onokudibana nazo?
1. Umba wamandla uphantsi, kwaye isixhobo sembuyekezo samandla asebenzayo asikwazi ukufakwa ekusebenzeni okanye sihlala sonakaliswa;
2. Utshintsho lomthwalo
3. Izinga eliphezulu lokuguquguquka kwe-harmonic current lichaphazela ukusebenza okuthembekileyo kokukhusela i-relay kunye nezixhobo zenkqubo yokulawula ngokuzenzekelayo;
4. Ukungalingani kwezigaba ezithathu ze-Intanethi kwinkqubo yonikezelo lwamandla kubi kakhulu.
Isisombululo sethu:
1. Ukuze kuncitshiswe umxholo we-harmonics ye-high-order, isixhobo sokucoca umthombo sifakwe kwi-400V yebhasi yesibini ye-step-down substation yokucoca.
2. Yamkela uhlobo oluguquguqukayo lwe-Hongyan uthotho lweejenereyitha zamandla asebenzayo ukubonelela amandla asebenzayo kwinqanaba ngalinye lenkqubo kwaye ulawule i-harmonics yenkqubo ngaxeshanye.
3. Khetha izixhobo zembuyekezo yokhuseleko oluguqukayo lweHongyan, uyilo ngokufanelekileyo i-capacitor kunye neeparamitha zothotho lwe-reactor ngokwemeko ye-pulse yangoku yenkqubo, uphucule umba wamandla ngembuyekezo yamandla asebenzayo, kwaye uphucule umgangatho wamandla ombane kaloliwe wedolophu kunye nenkqubo yokuhambisa.
4. Hongyan kaThixo izixhobo imbuyekezo oluguquguqukayo ukhuseleko wamkela indlela imbuyekezo hybrid yesigaba ezithathu ukwahlulwa imbuyekezo kunye nesigaba esithathu co-mbuyekezo, kwaye iqwalasela iimfuno imbuyekezo yesigaba ezithathu ukungalungelelani kwenkqubo software.
