Sezvo hurongwa hwemagetsi hunokura, chiyero chegridi chinoramba chichiwedzera, zvichikonzera kudiwa kwepamusoro kwekutaurirana kwemagetsi. Mabhatiri, sechinhu chakakosha cheiyo telecom power system, ane mhedzisiro yakananga pakuvimbika kwekutaurirana kwemagetsi. Kuitisa kuyedzwa kwehuwandu kuburikidza nekuchaja uye kuburitsa matenderedzwa inzira yakakosha yekuchengetedza kushanda kwebhatiri uye kuwedzera hupenyu hwebhatiri. Zvinoenderana nemirairo yekuchengetedza telecom power system, mabhatiri anoda kugara achigadziriswa. Kuenzaniswa nenzira dzakadai seyekupedzisira voltage kuyerwa uye yemukati kuramba kuyedzwa, kuyedzwa kwehuwandu kunopa kurongeka kwakanyanya. Mabhatiri achangobva kuisirwa anoda kuzara-kugona kuburitsa kuyedzwa, kuchiteverwa nekuyedzwa kwegore rekuburitsa simba. Kune mabhatiri ari kushanda kwemakore mana, semi-pagore kugona kuyedzwa kunodiwa. Kana bhatiri rikatadza kuwana 80% yehuwandu hwaro hwakayerwa mushure mebvunzo nhatu dzakateedzana, inofanirwa kutariswa kuti itsive.
Parizvino, matatu akajairwa bhatiri ekuyedza zvirongwa anoshandiswa zvakanyanya muinjiniya: dummy mutoro, DC / AC shanduko, uye DC / DC yakawedzera voltage zvirongwa.
Chishandiso chekuyedza simba chinonyanyo sanganisira yakakwira-frequency DC/DC bhatiri pack yakawedzera dunhu module, yakakwira-frequency DC/DC bhatiri pack inogara iripo yekuchaja module, macontactor, uye diode. Iyo sisitimu inoshanda mumatunhu matatu: yakamira inoyangarara charge, kuburitsa simba, uye inogara ichichaja. Idzi nyika dzinogadzira kutenderera kwakazara kwekushanda kwekuyedzwa kwehuwandu.
Standby Inoyangarara Charge State
Munzvimbo inoyangarara charge, iyo NC contactor K1 yakavharwa, uye NO contactor KM inovhura. Bhatiri riri online, ine rectifier inopa simba kune ese bhatiri pack uye mutoro. Muchiitiko chekudzima kwesimba kusingatarisirwi, bhatiri pack rinogona kupa zvakananga simba kumutoro, kuve nechokwadi chekusavhiringidzwa kwemagetsi.
Mufananidzo 1: Battery Pack in Standby Floating Charge State
Capacity Discharge State
Panguva yekuburitsa simba, iyo NC contactor K1 inovhura, uye iyo NO contactors KM neKC inovhara. Iyo yakakwira-frequency DC/DC bhatiri paki inosimudzira dunhu inoshanda. Bhatiri rinokwidziridzwa neDC/DC dunhu kune voltage yakakwira zvishoma pane rectifier voltage, nekudaro kutsiva rectifier mukupa simba kumutoro. Kana wapedza kuburitsa, sisitimu yacho inochinja ichienda kunogara ichichaja, uye inogara iripo yekuchaja yedunhu module inoshanda.
Mufananidzo 2: Battery Pack in Capacity Discharge State
Constant Current Charge State
Mushure mekubuda kwesimba, sisitimu inochinja ichienda kune inogara ichichaja. Iyo yakakwira-frequency DC/DC bhatiri paki inogara iripo yekuchaja yedunhu module inoshanda, ichigadzirisa otomatiki chaji kuhuwandu hweseti uchishandisa iyo yekutanga rectifier yekugara ichichaja. Sezvo magetsi ebhatiri achiwedzera kusvika kumagumo ekuchaja, iko kuchaja kunodzikira. Kana iyo yazvino inodonha pazasi pechikumbaridzo chemudziyo, sisitimu yacho inongopedza iyo inogara iripo yekuchaja maitiro. Iyo NC contactor K1 inovhara, ichimisa yakakwira-frequency DC/DC bhatiri paki inogara yazvino kuchaja yedunhu module, uye kudimbura KM neKC. Iyo bhatiri paki inodzokera kune yakamirira inoyangarara charge state.
Mufananidzo 3: Battery Pack in Constant Current Charge State
Izvo zviri pamusoro zvinotsanangura kuitwa kwesimba rekuyedza system yakavakirwa paDC/DC. Mhinduro yacho inogamuchirwa zvakanyanya nevagadziri veindasitiri. Semuyenzaniso, DFUN yakagadzira yakazara kure kure yepamhepo yekuyedza mhinduro, inowana yepakati kutonga kwenzvimbo dzakaparadzirwa kure, inochengetedza nguva, iri nyore, uye yakavimbika.
DFUN chiyero chekuyedza mhinduro , kuwedzera kune yekuyedza basa rekuita, inosanganisira chaiyo-nguva yekutarisa bhatiri uye bhatiri activation maficha, inogonesa kure, kutenderera-wachi yekutarisa uye kugadzirisa kwebhatiri mapaketi.
