Tsananguro yeChishandiso Chinodzivirira Kukwira

Chidziviriro cheSurge mudziyo unodzivirira wakagadzirirwa kudzivirira michina yemagetsi kuti isakuvadzwe nekuwedzera kwemagetsi kwenguva pfupi. Unoona kukwira kwemagetsi kusingawanzoitiki musystem uye unokurumidza kutsausa simba rakawandisa kuenda kuwire yepasi, nokudaro uchidzivirira kukuvara kwemidziyo inonzwisisika kubva mukukwira kwemagetsi.

Kushandiswa kweChishandiso Chinodzivirira Kuvhiya

Zvidziviriro zvema "surge protectors" zvinoshanda mumamiriro ekupindira zvakanyanya panguva yemamiriro ezvinhu akajairwa, zvichiita kuti circuit ishande zvakanaka. Zvisinei, kana magetsi emagetsi asingachinjiki akaitika—akadai seaya anokonzerwa nemakambani matsva emota, kuchinjana kwemutoro, kana kukwira kwemagetsi kunokonzerwa nemheni—mudziviriri anochinja ipapo ipapo kuenda kunzira yekupindira yakaderera, achiendesa simba rakawandisa pasi uye achidzivirira michina inonzwa kubva mukukuvadzwa. Kana mhepo yadzikira, mudziyo unozvigadzirisa woga kune mamiriro ayo ekupindira kwakanyanya, uchitangazve kungwarira kwawo kusingadzoreki kubva pakukanganiswa kwemagetsi.

Maitiro ekushandisa Key Device Protective Device

Dziviriro yemheni: dziviriro kubva pakukwira kunokonzerwa nemheni yakananga kana inductive.

Kuchinja-chinja kwegrid: kudzvinyirira overvoltages inokonzerwa nekushanda kwe grid switch, capacitor switching, nezvimwewo.

Dziviriro yemidziyo yemagetsi: chengetedza zvishandiso zvine hungwaru zvakaita semakombiyuta, midziyo yekutaurirana, uye midziyo yemumba.

Masisitimu emaindasitiri: chengetedza mashandiro akagadzikana emidziyo mikuru yakadai sePLC, inverters, uye sensors.

Kuiswa kweChishandiso Chinodzivirira Kukwira

• Simba remagetsi rinofanira kuchekwa risati raiswa, uye kushanda kwaro kwarambidzwa zvachose;
• Zvinokurudzirwa kubatanidza fuse kana circuit breaker muzvikamu zvakatevedzana kumberi kwemodule;
• Ndapota batanidzai zvinoenderana nedhayagiramu yekuisa panguva yekuisa, apo DC+ iri mutsetse wakanaka, DC- iri mutsetse usina kunaka, uye PE iri mutsetse wepasi. Musazvibatanidze zvisirizvo. Mushure mekunge kuiswa kwapera, vharai switch yecircuit breaker (fuse) uye tarisai kana mamiriro ekushanda ari akajairwa;
• Mushure mekunge kuiswa kwapera, isa module nemazvo uye tarisa kana module iri kushanda nemazvo;
• Munguva yekushandisa module, mamiriro ewindo rekuratidzira zvikanganiso anofanira kuongororwa nguva nenguva. Kana hwindo rekuratidzira zvikanganiso ratsvuka kana kuti remote signal terminal ikaburitsa chiratidzo chealarm, zvinoreva kuti module ine zvikanganiso uye inofanira kugadziriswa kana kutsiviwa nenguva;
