Kunzwisisa mabasa uye kukosha kwevadziviriri vekuvhiya (SPDs)

Surge midziyo yekudzivirira(SPDs)kuita basa rakakosha mukuchengetedza magetsi ekugovera network kubva pakuwedzeredza uye mafambiro emhepo.Iko kugona kweSPD kudzikamisa overvoltages mune yekugovera network nekutsaudzira surge ikozvino zvinoenderana neaya ekudzivirira ekudzivirira, iyo mechaniki chimiro cheSPD, uye yekubatanidza kune network yekugovera.SPDs dzakagadzirirwa kudzikamisa overvoltages enguva pfupi uye kushandura inrush currents, kana zvese zviri zviviri.Iine kanenge kamwe chete nonlinear chikamu.Zvichitaurwa zviri nyore, maSPD akagadzirirwa kudzikamisa overvoltages enguva pfupi kudzivirira kukuvara kwemidziyo.

Kukosha kweSPD hakugone kuwedzeredzwa, kunyanya muzuva rino uye zera apo midziyo yemagetsi inonzwisisika inowanikwa munzvimbo dzekugara uye dzekutengesa.Sezvo kuvimba nezvishandiso zvemagetsi nemidziyo zvichiwedzera, njodzi yekukuvadzwa kubva pakusimba kwemagetsi uye kuwedzeredza kwechinguvana kunowedzera kukosha.SPDs ndiwo mutsara wekutanga wekudzivirira kurwisana nemhando iyi yekuvhiringidza kwemagetsi, kuve nechokwadi kuti midziyo yakakosha inodzivirirwa nekudzivirira nguva yekuderera nekuda kwekukuvara.

Mabasa eSPD ane mativi akawanda.Iyo haingogumiri kupfuudza overvoltages nekutsausa mafungu emhepo, asi zvakare inovimbisa kuti magetsi ekugovera network inoramba yakagadzikana uye yakavimbika.Nekutsausa mafungu ekuvhiya, maSPD anobatsira kudzivirira kushushikana kunogona kutungamira mukupunzika kwekudzivirira, kukuvara kwemidziyo uye njodzi dzinogona kuitika.Pamusoro pezvo, ivo vanopa mwero wedziviriro yemidziyo yemagetsi inonzwisisika iyo inogona kubatwa nekushanduka kudiki kwemagetsi.

Izvo zvikamu mukati meSPD zvinoita basa rakakosha mukuita kwayo kwese.Nonlinear zvikamu zvakagadzirirwa kuchengetedza michina yakabatana nekupa yakaderera-impedance nzira yekuvhiya mafungu kuti apindure kune overvoltage.Iyo SPD's mechanical structure inobatsirawo pakuita kwayo, sezvo ichifanirwa kukwanisa kumira simba rekuvhiya pasina kukundikana.Pamusoro pezvo, kubatana kune network yekugovera magetsi kwakakosha zvakare, sezvo kuisirwa kwakaringana uye kudzika kwakakosha pakushanda kwakakwana kweSPD.

Paunenge uchifunga nezve kusarudzwa kweSPD uye kuisirwa, zvakakosha kuongorora izvo chaizvo zvinodiwa zvemagetsi system uye midziyo yainotsigira.MaSPD anowanikwa mumhando dzakasiyana-siyana uye zvigadziriso, kusanganisira Type 1, Type 2 uye Type 3 zvishandiso, imwe neimwe yakakodzera kune akasiyana maapplication uye nzvimbo dzekuisa.Zvinokurudzirwa kubvunza nyanzvi inokwanisa kuona kuti SPD yakasarudzwa nemazvo uye yakaiswa kuti ipe nhanho inodiwa yedziviriro.

Muchidimbu, michina yekudzivirira yekuvhiya (SPDs) inoita basa rakakosha mukuchengetedza magetsi ekuparadzira network uye neanonzwa emagetsi emidziyo kubva kune zvinokuvadza zvinokonzeresa overvoltage uye kuvhiya kwazvino.Kugona kwavo kudzikamisa overvoltages enguva pfupi uye kutsausa inrush currents kwakakosha kuchengetedza kugadzikana uye kuvimbika kwemagetsi masisitimu.Sezvo midziyo yemagetsi inoramba ichiwedzera, kukosha kweSPDs mukudzivirira kubva kune simba rekuwedzera uye kupera kwepamusoro kwenguva pfupi hakugoni kuderedzwa.Kusarudzwa kwakakodzera, kuiswa uye kugadzirisa kweSPDs kwakakosha pakuchengetedza kuenderera mberi kwekuchengetedzwa kwemidziyo yakakosha uye kusakanganiswa kushanda kwemagetsi emagetsi.
