A Surge Dziviriro Chishandiso (SPD) chinhu chakakosha mumasisitimu emagetsi emazuva ano, akagadzirirwa kuchengetedza michina kubva kumagetsi emagetsi. Aya mapfupi, anowanzo kukonzerwa nekurova kwemheni kana utility grid switching, anogona kukonzeresa nekukasira uye kwakanyanya overvoltages. Basa rekutanga reSPD ndere kudzikamisa aya anopfuudza overvoltages uye kutsausa kuwanda kwazvino kusvika pasi, nekudaro kudzivirira kukuvadzwa kwemidziyo yemagetsi inonzwisisika uye kuve nechokwadi kuenderera mberi kwekushanda. Basa rayo rakakosha mune yakazara njodzi manejimendi kune ese ekugara uye ekutengesa kuisirwa.

A Miniature Circuit Breaker inoshanda seyakakosha otomatiki kudzivirira chikamu mukati memagetsi ekugovera masisitimu. Nheyo yayo yekushanda inotsamira pane zvinopisa uye magineti maitiro ekuona abnormal ikozvino mamiriro. Pakuona kukanganiswa kwakaramba kuripo kana kupfupi-sekiti, mudziyo unokurumidza kukanganisa dunhu. Ichi chiito chekukurumidza chinodzivirira kukanganisa kunogona kuitika kune wiring insulation uye midziyo yakabatana. Iyo yakakosha dhizaini inovimbisa zvese kuchengetedzwa kwekushanda uye kuvimbika kwehurongwa.

Mumazuva ano emagetsi masisitimu, kunyanya muzuva uye maindasitiri ekushandisa, basa rekudzivirira redunhu rakakosha. Dc Fuse chinhu chakakosha chakagadzirirwa kukanganisa simba zvakachengeteka panguva yezviitiko zvenguva pfupi kana pfupi-circuit. Iyo BYPV-63 yakatevedzana fuse inobata inomiririra yakasarudzika mhinduro kune idzi high-voltage DC nharaunda, ichipa hwaro hwakachengeteka uye hwakavimbika hwechinhu chakakosha chefuse. Dhizaini yaro inotarisa pakuchengetedza kuchengetedzwa kwehurongwa uye kuvimbika kwemidziyo nekufambisa kushanda kwakaringana kwefuse.

Kuvimbika uye kushanda kwe photovoltaic system kunonyanya kuenderana nekushanda kwezvikamu zvayo zvinobatanidza. A Pv Connector inyanzvi yemagetsi interface yakagadzirirwa kugadzira yakachengeteka uye yakaderera-resistance links mukati me solar array. Iyo PV-BY-03 yakatevedzana, mhando-yakaiswa panhizha, inogadzirwa kuti izadzise basa iri, ichipa yakasimba yekubatanidza nzvimbo yekubatanidza simba kubva kune akawanda mapaneru kana kubatanidza kune inverters. Dhizaini yaro inotungamira kugadzikana kwekushanda kwenguva refu pasi pemamiriro ezvinhu akaoma akajairika ekuisa solar.

Iyo Miniature Circuit Breaker (MCB) chinhu chakakosha mukumisikidzwa kwemagetsi kwemazuva ano, ichipa dziviriro yakakosha kubva pakukanganisa kwepamusoro uye pfupi-circuit. Nepo iyo MCB pachayo chiri chidziviriro chakakwana, mashandiro ayo anogona kukwidziridzwa zvakanyanya kuburikidza nemhando yezvishandiso zvehunyanzvi. Izvi zvikamu zvakagadziridzwa kuti zvibatanidze zvisina musono neiyo core breaker, zvichipa kudzora kwakakwidziridzwa, kutarisa, uye kuchengetedza kugona kune yakasimba simba remagetsi manejimendi system.

Iyo yakachengeteka uye inoshanda kushanda kwe photovoltaic (PV) system inotsamira pane yakasimba zvikamu zvakagadzirirwa zvakanangana nezvino (DC) application. Chinhu chakakosha mukuseta kwakadaro iPV Isolator Switch, chishandiso chakagadzirirwa zvakanangana nezvinodiwa zvakasiyana zvekugadzira simba rezuva. Inoshanda sechinyorwa chekudzima nzvimbo, ichigonesa kuparadzaniswa kwemaseketi emagetsi ekugadzirisa, kuisirwa, kana panguva yekukurumidzira, nekudaro kuve nechokwadi chekuchengetedzwa kwevashandi nemidziyo.
