Sei chidziviriro chekukwira chichifanira kuiswa mubhokisi rekugovera?

Basa remudziyo wekudzivirira kukwira kwemvura(SPD) mubhokisi rekugovera:
Chidziviriro chekuvhuvhuvhu chakaiswa kuseri kwechinhu chinovhura circuit mukati mebhokisi rekugovera, uye basa rayo guru nderekudzivirira mheni. Zita rayo rakazara nderekuti: chidziviriro chekuvhuvhuvhuvhuvhuvhuvhuvhuvhuvhu.
Mudziyo uyu wekudzivirira magetsi akawandisa wakagadzirirwa kudzivirira njodzi dzemheni, uye zvakakoshawo kufunga nezvemagetsi akawandisa ari mumutsara wekugovera magetsi akaderera. Mudziyo uyu unodzivirira magetsi akaderera musystem yemagetsi akaderera.
Mvura ine dutu inodzivirira bhokisi rekuparadzira kubva mukurwiswa nemheni, uye voltage yakakwira, uye simba guru rinodira pasi nekukurumidza kubva pawaya yekudzivirira mheni. Mudziyo wekudzivirira kukwira kwemvura ndiwo muchengeti webasa redu rezuva nezuva rekuchengetedza.
Zvidziviriro zvekuvhiya zvakakodzera munzvimbo dzakasiyana-siyana:
Kazhinji inoiswa mumabhokisi ekuparadzira, nzvimbo dzemakombiyuta, makamuri ekutaurirana, makamuri ekudzora elevator, makamuri eTV yetambo, makamuri ekudzora otomatiki ekuvaka, nzvimbo dzekudzima moto, makamuri ekudzora otomatiki eindasitiri, makamuri ekudzora michina yekushandura frequency, makamuri ekurapa echipatara, mayuniti ekuchengetedza varwere vakanyanya uye mabhokisi ekuparadzira ane michina yekurapa yemagetsi, nezvimwewo. Pamusoro pezvo, inogona zvakare kuiswa mubhokisi guru rekugovera mwenje rezvivakwa zvekugara zviri pasi pematanhatu.
Maitiro ekugadzirisa chidziviriro chesimba mubhokisi rekugovera:
SPDinogona kukamurwa kuita dziviriro yemheni yeClass A, Class B, Class C, uye Class D, iyo inotsanangurwa zvichienderana nevoltage uye kugona kwebhokisi rekugovera. Kugoverwa kwe380V kunoshandisa dziviriro yemheni yeClass B, 40KA~60KA. Bhokisi rekugovera re220V rinoshandisa dziviriro yemheni yeClass C, 20KA~40KA.
Sei bhokisi rekugovera richifanira kunge rakashongedzwa nemudziviriri we surge?
Panguva yekuburitswa kwemheni, voltage inenge yakakwira, magetsi akawandisa, uye nguva yekuburitswa kwesimba ipfupi. Hazvina kukwana kuvimba chete nekudzivirira mheni dzekunze (tsvimbo dzemheni, nezvimwewo). Mafungu emheni anopinda zvakananga kana zvisina kunanga patambo dzemagetsi, tambo dzemasaini, tambo dzemagetsi dzeantenna, uye mapaipi esimbi. Mheni inozobuda nekupfuura simba zvichakonzera kukuvadzwa kukuru kune michina yemagetsi, michina yemagetsi, uye masisitimu enetwork yeruzivo.
Kukuvadzwa kunokonzerwa nemheni ndeimwe yenjodzi huru dzechisikigo. Mheni inosara uye mheni inopinza inogadzirwa nemheni zvicharamba zvichikanganisa michina yemagetsi inoshandiswa mumba, zvichikonzera mapfupi mumidziyo yemagetsi inoshandiswa mumba, zvichikonzera kurasikirwa zvakananga senge kutsva nekuputika.
