Chii chinofanira kucherechedzwa kana quasi-synchronized parallelling yekuunganidza jenareta?
Quasi-simultaneous association inzira yemaoko.Kunyangwe kuvhiya kwacho kwakatsetseka kana neimwe nzira kune kudyidzana kukuru neruzivo rwemushandisi.Kuti udzivise kushamwaridzana munguva dzakasiyana, kunamatira kune matatu mamiriro haabvumidzwe kuvhara.
1. Kana chidimbu chetafura yekubatanidza chikasvetuka, hachigone kuvharwa, nekuda kwekuti panogona kunge paine tepi sensation mukati meiyo tafura yekuwiriranisa, iyo isingagoni kuratidza akakodzera matambudziko akafanana.
2. Kana tafura yenguva imwe chete ikashanduka zvakare nekukurumidza, inoratidza kuti mutsauko we frequency pakati pejenareta yakagadziridzwa kuti ienzaniswe uye iyo yemamwe akasiyana muunganidzwa wejenareta wakakurawo.Nekuda kwekuti nguva yekuvhara yedunhu inotyora inonetsa kuziva, muparadzi wedunhu kazhinji haana kuvharwa panzvimbo yekuwiriranisa.Hazvibvumirwi kuvhara.
3. Kana chidimbu chetafura yekuenzanisa chikamira panzvimbo yekubatanidza, hazvibvumirwi kuvhara shanduko kana yamira.Izvi ndezvokuti kana kuwanda kweimwe yejenareta kunotanga kuchinja kamwe kamwe panguva yekuvhara nzira yekuputsa, zvinokwanisika kuti muputsi avhare pane zvisiri-synchronized factor.
4. Nzira yekugadziridza sei reverse simba sensation yeparallel system?
Kana 2 jenareta seti dziri juxtaposed pasina matani, pachave nedambudziko re frequency musiyano pamwe nekusiyana kwevoltage pakati pemaunganidzwa maviri ejenareta.Uye pamaturusi ekutarisisa (ammeter, simba mita, simba element mita) yemasisitimu ese ari maviri, iyo chaiyo reverse simba mamiriro inoratidzwa, imwe isimba rekudzokera kumashure rinokonzerwa nekumhanya kusingaite (nguva dzose), uye imwe inokonzereswa nekusiyana kwemagetsi. .Inverted basa, kugadziridzwa kwayo kunoenderana ne:
1. Kugadziriswa kweiyo reverse simba chiitiko chinokonzerwa nekuwanda: kana mafambiro eaviri masisitimu asina kuenzana, pamwe nekusiyana kwakakura, icharatidzwa pane chiridzwa (ammeter, simba mita), ikozvino ye mudziyo une kumhanya wakakwira unoratidza kukosha kwakanaka, pamwe nemamita emagetsi inoratidza kukosha kwakanaka.Simba, kune rumwe rutivi, riripo rinoratidza kukosha kwakashata, uye zvakare simba rinoratidza kukosha kwakashata.Parizvino, shandura chiyero (frequency) yeimwe yezvikamu, uye shandura iyo maererano nechiratidzo chemamita emagetsi, uye shandura chiratidzo chemamita emagetsi kune zvachose kwete.Ita zviratidzo zvemagetsi zvezvikamu zviviri kwete, kuitira kuti mazinga ekutenderera (nguva dzose) yezvishandiso zvose zviri zviviri zvakafanana.Nekudaro, kana ammeter ichiri kuratidza izvozvi, iyi ndiyo reverse simba chiitiko chakakonzerwa nemusiyano wevoltage.
2. Kugadziridzwa kweiyo reverse simba chiitiko chakakonzereswa nekusiyana kwevoltage: kana zviratidzo zvemamita emagetsi emaseti maviri ejenareta ese ari aiwa, uye ammeter ichine chiratidzo chazvino (kureva, imwe inverted uye imwe yakanaka chiratidzo), iyo voltage. kugadziridzwa kwepakati pemajenareta seti kunogona kugadziridzwa.Kana uchichinja knob, zvinoenderana nechiratidziro cheammeter uye zvakare chikamu chesimba.Bvisa chiratidzo che ammeter (ndiko kuti, gadzirisa kuti ive kwete zvachose).Mushure mekunge ammeter isina chiratidzo, gadzirisa chikamu chesimba kune lag inopfuura 0.5 zvichienderana nechiratidzo chemagetsi element mita.Kazhinji, inogona kugadziridzwa kusvika 0.8, inova ndiyo yakanyanya kunaka mamiriro.
5. Jenereta kuchengetedzwa kwedunhu
1. Reverse simba The reverse simba sensation inounzwa nemusiyano muyero (nguva dzose) uye zvakare voltage yekuunganidza jenareta, ndiko kuti, imwe jenareta yekuunganidza ine simba rakanaka, nepo imwe yakasiyana-siyana ine simba rakashata.Kureva kuti, hurongwa hune simba rakashata hunouya kuva matani ikozvino (nguva yakawanda yegadziriro iyi yakaderera uye chiyero chekutenderera hachina kufanana).Kana ma voltages asina kufanana, sisitimu ine yakakwira voltage zvirokwazvo ichapa inopindura ikozvino uye zvakare reactive voltage kumudziyo neyakaderedzwa voltage (ammeter yeiyi unit inoratidza nzira yakanaka), iyo inowedzera kuwedzera phase control system mu simba rekupa system.Iyo unit ine yakaderera voltage inoguma yave mijenya hombe panguva ino, ichiwana hombe reactive ikozvino kuchengetedza voltage yakaenzana yezvikamu zviviri (ammeter yeiyi system inoratidza reverse direction).Paunenge uchitarisa, gadzirisa voltage yeimwe unit yakakura kana kudzikisa voltage yeimwe system, zvichiita kuti mudziyo uve nereverse power iripo, uyezve kushanda kwayo kune chekuita ne20% yeyakayerwa iripo.Iyo reverse simba relay inomhanya, nzendo, uye zvakare maaramu, asi hairegi.
2. Overcurrent: Simba rakayerwa rejenareta seti ndeyechokwadi, uye huwandu hwayo hwekuremedza hwakaderera zvakanyanya, kazhinji maererano ne5% yesimba renzvimbo.Iyo inobvumidzwa yekuremedza nguva ndeye 15 ~ 30 maminetsi, uye zvakare iyo yakawanda haina kukura kupfuura makumi matanhatu mins.Iyo jenareta seti ichapisa, uyezve tambo yekudzivirira ichadzikiswa, izvo zvinoderedza hupenyu hwebasa.Nokuda kwechikonzero ichocho, kana pasina chidikanwi chakasiyana-siyana paunotanga kudzivirira kwepamusoro, kuchengetedzwa kwepamusoro kunogona kuiswa pa 110% yehuwandu hwemazuva ano.Munguva yese ye-on-load bvunzo, huya ikozvino kune 110% yeyakayerwa ikozvino, pamwe neiyo overcurrent relay ichaita.Rwendo, alarm system, hapana kuvhara.
3. Overvoltage: Kana majenareta seti akashandiswa zvakafanana, imwe yeanonyanya kutya ndeyekuti magetsi emagetsi achatenderera.Pangosvika iyo voltage ye oscillating system ichiwedzera, zviri nyore kukonzeresa kuputsika kwemidziyo yemagetsi uyezve midziyo yekupa magetsi, uye maturusi emagetsi uye zvakare maturusi emagetsi anozomiswa nemumwe.Nechinangwa ichi, maseti ejenareta anoshandiswa mukuenderana akashongedzwa nekudzivirira kwepamusoro, uyezve kukosha kwayo kweseta i105% yemagetsi akayerwa ndiyo inonyanya kushanda.Short-circuit over-voltage relay, rwendo pamwe nekusiya, alarm chiito.
