Nhanganyaya: Simba ratinopihwa nemagetsi grid system rinowanzo dzikamiswa zvine simba.Kazhinji, chero bedzi magetsi ari mashoma mukati mehuwandu hwakatarwa, tinogona kuwana nzvimbo iri nani yekushandisa magetsi.Asi magetsi emagetsi haapi magetsi akakwana.Pamusoro pezvo, hapana nzira yekuti vagadziri vemidziyo vape michina isingadzivirirwe kune voltage dips yemidziyo yese yemagetsi.Dambudziko revoltage sag rinokonzera kukanganisa kwakawanda uye dambudziko kuhupenyu hwezuva nezuva nekugadzirwa.Saka ndeapi maturusi akanaka ekubhadhara aripo ekudzikisa kukanganiswa kwemagetsi sags?Kazhinji, tinoshandisa marudzi matatu emidziyo yemuripo: UPS (Uninterruptible Power Supply), Solid State Transfer Switch (SSTS), uye Dynamic Voltage Restorer (DVR—Dynamic Voltage Restorer).Nekuisa izvi zvigadziriso zvemuripo pakati pesimba rekupa system uye network yemushandisi magetsi.Izvi zvitatu zvekuripa zvine zvazvakanakira uye zvazvakaipira.
Unterruptible Power Supply (UPS-Uninterruptible Power Supply): UPS kwenguva pfupi, ndiyo inonyanya kushandiswa mudziyo wekudzikisa voltage sag muripo.Nheyo yekushanda yeUPS inowanzo shandisa simba remakemikari senge mabhatiri kuchengetedza simba remagetsi.Kana wasangana nedambudziko rekutadza kusimba kwemagetsi emagetsi system, iyo UPS inogona kushandisa simba rakachengetwa pachine nguva kuchengetedza magetsi kwemaminetsi akati wandei kusvika maawa akati wandei.Nenzira iyi, iyo voltage sag dambudziko rinokonzerwa nemagetsi emagetsi system rinogona kugadziriswa mukati meimwe nguva yenguva.Asi UPS ine zvakare yakawedzera kushaya simba kwayo.Magetsi anochengetwa kuburikidza nemakemikari simba, uye iyi dhizaini pachayo inoshandisa simba rakawanda.Mabhatiri ekuchengetedza magetsi haangotore nzvimbo yakawanda chete, asi zvakare akaoma chaizvo kuchengetedza.Panguva imwecheteyo, kune iyo mitoro ine simba guru pane gridhi, inofanirwa kuwedzera simba rayo pachayo.Zvikasadaro, zviri nyore kuita kuti bhatiri rekuchengetedza simba rikundike.
Solid State Transfer Switch (SSTS—Solid State Transfer Switch), inonzi SSTS.Mukuita mafekitori ekugadzira maindasitiri kana kushandiswa kwemagetsi chaiko nevashandisi.Kazhinji kune mabhazi maviri akasiyana kana mitsara yemagetsi kubva kune akasiyana substations emagetsi.Panguva ino, kana imwe yemagetsi emagetsi iine kukanganisa kana sag yemagetsi, inogona kukurumidza (5-12ms) kuchinjwa kune imwe magetsi nekushandisa SSTS, nokudaro kuve nechokwadi chekuenderera kwetambo yose yemagetsi.Kubuda kweSSTS kwakanangana neiyo UPS mhinduro.Haisi chete iyo mutengo wese wekudyara kwemidziyo yakaderera, asi zvakare iri mhinduro yakanaka kune kudonha kwevoltage yeakakwira-simba mitoro.Kuenzaniswa neUPS, SSTS zvakare ine akawanda mabhenefiti akadai semutengo wakaderera, diki tsoka, uye gadziriso-yemahara.Izvo chete zvisingabatsiri ndezvokuti yechipiri bhasibha kana mitsara yemabhizimisi kubva kune dzimwe nzvimbo dzakasiyana-siyana inodiwa kune magetsi, kureva, simba rekuchengetedza rinodiwa.
Dynamic Voltage Restorer (DVR—Dynamic Voltage Restorer), inonzi DVR.Kazhinji, ichaiswa pakati pemagetsi emagetsi uye midziyo yekutakura.Iyo DVR inogona kubhadharira rutivi rwekuremerwa kune yakakodzera kudonha voltage mukati memilliseconds, kudzoreredza divi remutoro kune yakajairika voltage, uye kubvisa kukanganiswa kwevoltage sag.Basa rakakosha reDVR nderekupa nekukurumidza zvakakwana nguva yekupindura, uye inogona zvakare kuwedzera kudzika kwevoltage sag dziviriro.Kudzika kwekudzivirira kunogona kududzirwa semhando yevoltage sag iyo DVR inogona kugamuchira.Kunyanya kune vashandisi vefekitori, kazhinji kutaura, kana paine voltage sag fluctuation panguva yenguva dzose kushanda kwemuchina nemidziyo, zvinozotungamira kune dambudziko muhuwandu hwekubudirira kwekugadzira, ndiko kuti, pachave nezvigadzirwa zvisina kukwana.Nekushandisa DVR, zvakajairwa mashandiro efekitari zvinogona kuvimbiswa, uye kukanganisa kunokonzerwa nekushomeka kwemagetsi hakugone kunzwika.Asi iyo DVR haina nzira yekudzoreredza kukanganisa kwevoltage inodarika kudzika kwekudzivirira kwevoltage sag.Naizvozvo, kana kudonha kwevoltage kuri mukati meiyo voltage sag dziviriro kudzika, iyo DVR inogona chete kutamba basa rayo rakakodzera kana ichinge yavimbiswa kusakanganiswa.
Iyo DVR inogadzirwa neHongyan Electric ine yakavimbika practicability: yakakwirira kuvimbika, yakarongedzerwa mitoro yemaindasitiri, yakakwira sisitimu kushanda zvakanaka, kukurumidza kupindura, hukuru hwekugadzirisa, hapana harmonic jekiseni, yakazara dhijitari yekudzora tekinoroji yakavakirwa paDSP, yakavimbika High performance, advanced parallel kuwedzera. basa, modular dhizaini, multi-function panel ine graphic TFT yechokwadi ruvara kuratidza, zvachose kugadzirisa-isina, yakaderera mutengo wekushandisa, hapana kudiwa kwemidziyo yekutonhodza, compact chimiro dhizaini, diki tsoka uye zvimwe zvakawanda zvakanaka.
