Sezvatinoziva tese, iyo yakanakira magetsi nharaunda yatinotarisira kuwana ndeyekuti magetsi emagetsi grid system anogona kutipa yakagadzikana voltage.Kana tikasangana nekudonha kwechinguvana kana kudonha kwemagetsi (kazhinji kudonha kamwe kamwe, inodzokera kune yakajairika munguva pfupi).Kureva kuti, chiitiko chekuti kukosha kunoshanda kweiyo voltage yekugovera kamwe kamwe inodonha uye yobva yasimuka nekupora munguva pfupi.Sangano reInternational Institute of Electrical and Electronics Engineers (IEEE) rinotsanangura voltage sag sekukurumidza kudonha kwehukoshi hunoshanda hwemagetsi ekupa kusvika pa90% kusvika 10% yemutengo wakayerwa.%, uye wozosimuka kudzokera kupedyo neyakajairwa kukosha, iyo nguva ndeye 10ms ~ 1min.Kana voltage sag yaitika, zvinounza kukuvadza kukuru kuindasitiri.Nekuti voltage sag inoonekwa seyakanyanya kukuvadza simba remhando dambudziko kune kugadzirwa kwemaindasitiri.
Kazhinji, voltage sag inokanganisa zvese zvemagetsi zvakabatana nedunhu.Kunyanya kune aya maindasitiri ekugadzira nekugadzirisa anoda kunyatsojeka, kana voltage sag yasangana, inokonzeresa kurasikirwa uye kutambisa zvigadzirwa zvemazvo.Kunyanya zvakakomba, zvinototungamira kune huwandu hukuru hwezvinhu zvakagadziriswa kusashanda.Izvo zvakare njodzi huru kuhupenyu hwemidziyo yemagetsi.Panguva imwecheteyo, iyo voltage sag ichakonzerawo huwandu hukuru hweharmonics.
Mazhinji maindasitiri ave kushandisa otomatiki kana semi-otomatiki michina.Voltage sag inogona kutungamira mukusafungira otomatiki kana semi-otomatiki zvishandiso.Ingave yakakonzera kumbomira kana kusashanda zvakanaka.Zvese zvinogona kuita kuti frequency converter imire, uye kunyange kukonzera akasiyana-siyana ekudzivirira magetsi ekutanga.Kune marudzi akasiyana-siyana emamota akajairika muhupenyu hwezuva nezuva.Semuyenzaniso, ma elevator nemaTV anombomira oita kuti mota itangezve kamwe kamwe.
Kana izvi zvigadzirwa zvemagetsi zvisingakwanisi kushanda zvakajairwa, nekuda kwekuitika kamwe kamwe, mutsara wese wekugadzira uchakanganiswa.Patinoda kudzoreredzwa kwakarongeka kwemutsara wese wekugadzira.Izvo zvakaenzana nekuwedzera mutengo wenguva uye mutengo wevashandi pasina.Kunyanya kune idzo nzvimbo dzine zvinodiwa pamazuva ekutumira uye ekugadzira.
Huchava netapuroi paupenyu hwezuva nezuva?Manzwiro akanyanya kujeka ndeokuti zvinokonzeresa kukuvadza kune komputa, izvo zvinozokonzeresa kudzima uye kurasikirwa nedata (kombuta ichavharika zvakananga, zvisinei kuti mangani mazwi awakanyora nekurongedza, ichave yanyanya kunonoka kuchengetedza. nekuda kwekuvhara kamwe kamwe).Kunyanya idzo nzvimbo dzakanyanya kukosha, senge midziyo yechipatara, traffic command system uye zvichingodaro.Muenzaniso wakapfava zvikuru.Imba yekuvhiya yechipatara iri kuvhiyiwa.Kana paine voltage sag, ingave mwenje usina mumvuri kana zvimwe zviridzwa zvakanyanyisa, kana yangodzimwa uye yatangwazve, inova nekukanganisa kukuru pakushanda.Kukundikana kwerudzi urwu kunokonzerwa netsaona yechiridzwa hachigamuchirwi nemunhu wese.
Kune mafiriji emagetsi ekudzora, kana voltage sag yaitika, mutongi anocheka mota yefiriji.Kune indasitiri yekugadzira chip, kana voltage yadzikira kupfuura 85%, ichaita kuti dunhu remagetsi rishaye basa.
Iyo inonzwisisika indasitiri voltage sag control mudziyo inogadzirwa neHongyan Electric inogona kunyatso kugadzirisa akatevedzana mhedzisiro inokonzerwa nevoltage sag.HY akateedzana anonzwa indasitiri voltage sag control midziyo - hukuru hwechigadzirwa mu: yakakwirira kuvimbika, yakarongedzerwa mitoro yemaindasitiri, yakakwira sisitimu inoshanda, kukurumidza kupindura, yepamusoro yekugadziridza kuita, hapana harmonic jekiseni, yakazara dhijitari yakavakirwa paDSP Kudzora tekinoroji, kuvimbika kwepamusoro, kufanana kwepamberi. basa rekuwedzera, modular dhizaini, yakawanda-inoshanda ine graphic TFT yechokwadi ruvara kuratidza.
