A circuit breakeris a switch inokwanisa kubatanidza nekubvisa dunhu.Zvinoenderana nemabasa ayo akasiyana, inogona kukamurwa kuita mhepo inotyora uye gasi-insulated simbi-yakavharirwa switchgear (GIS).
Zvakanakira wedunhu breaker: nyore chimiro, mutengo wakachipa, unogona kuvandudza zvakanyanya kunaka kwekuvaka kweprojekiti;hombe yekupwanya simba, simba rekuremedza rakasimba, kusawanzobatana nekutyoka kwemutsara;basa rekudzivirira rakazara, rinogona kukurumidza kugura dunhu munguva pfupi pfupi.
Zvikanganiso zvemagetsi emagetsi: kupisa kukuru uye chiedza chepamusoro che arc chinogadzirwa panguva pfupi pfupi;kuvhiya kazhinji hakugone kuitwa;nguva yakakwana inodiwa kuti simbi iri mufiyuzi idzokere painonyungudika.
Apo iyocircuit breakerinoshandurwa kubva pamhepo inochinja kuenda kuGIS, iyo inotevera mirau ichasangana:
1) Mutambo wedunhu unofanirwa kuve wakanyatso kudzika panguva yekuisa uye kushandiswa;
2) Kuchengetedza kwakanaka kunofanira kuchengetedzwa pakati peGIS switchgear uye pasi;
3) Nzvimbo yekuisa inofanira kunge iine nzvimbo dzakanaka dzemvura.
Function
A circuit breakerishanduko inoshandiswa kubatidza nekudzima dunhu, uye kazhinji ine basa rekubatidza nekudzima dunhu, uye inewo mabasa akadai sekudzivirira kwedunhu pfupi uye kudzivirira kuwandisa.Panguva imwecheteyo, kukwanisa kwayo kuputsa kwakasimba zvikuru, uye inogona kukurumidza kugura dunhu munguva pfupi.
1. Sechigadziro chepasi-voltage simba rekugovera, muchengeti wedunhu ane basa rekudzivirira dunhu kubva pakuremerwa, kupfupika uye kuderera.
2. Mutsigiri wedunhu ane zvakanakira simba rakasimba rekucheka ikozvino uye nekukurumidza chiito;iyo inewo iyo pfupi-yekudzivirira yekudzivirira basa reiyo pfupi-circuit ikozvino yekuputsika kwechikamu chimwe.
3. Sechigadziro chemagetsi emagetsi emagetsi, muparadzi wedunhu anogona kuvhara kana kubvisa dhipatimendi remagetsi ekushanda kwemazuva ose mukati menguva yakatarwa;inogona kuramba ichipa simba kumutsara pasina kukundikana, uye inogonawo kushandiswa semotor stator insulation uye dunhu kana zvichidikanwa.Maseketi ekubatsira emagetsi akasiyana siyana.
Install
1. Usati waiswa, tarisa kutaridzika kwemupumburu wedunhu nekuda kwekutsemuka, wozovhura chivharo chekupedzisira chevhavha yedunhu, uye tarisa chiziviso uye nameplate pachivharo chekupedzisira.Tarisa uchipesana nemuenzaniso wakataurwa mubhuku rekushandisa.
2. Kuiswa kwemugadziri wemagetsi kunofanira kusangana nezvinodiwa zvekugadzira, uye kunofanira kuenderana nechinzvimbo chekuisa chezvimwe zvigadzirwa zvemagetsi pamagetsi ekuparadzira simba kana chigadziro chekugovera simba.Hazvibvumirwi kuisa kana kupfuura pedyo nemimwe midziyo yemagetsi nemidziyo (switch).
3. Mutambo wedunhu uye zvishandiso zvayo zvinofanira kunge zvakavimbika pasi.Kune akawanda-layer wiring, socket yepamusoro uye cable shielding layer inofanirawo kuiswa pasi.
4. Nzira yekushanda inofanira kuiswa pasi pekuedzwa kwemutoro usati waputsika kuti uone kuti chiito chayo chinoshanduka uye chakavimbika chisati chaparara.Tarisa uone kana iyo wiring yakarurama isati yaputsika, zvikasadaro haigoni kubviswa nebofu.
5. Kana muchengeti wedunhu akaiswa mubhokisi resimbi, mabhoti ekusimbisa mubhokisi haabvumirwi kusunungura;kuwirirana pakati pebhokisi rekugadzirisa mabhoti uye thread inofanira kuva yakavimbika;iyo inogadzirisa nuts inofanira kuva anti-loosening screws;iyo screw holes inofanira kudhirwa mechanically;
Dzivirira
Kana iyo system ikakundikana, senge mota overload, pfupi dunhu, nezvimwewo, njodzi huru nemhedzisiro yakakomba inogona kudziviswa, izvo zvinoda kushandiswa kwemagetsi emagetsi kuchengetedza midziyo yemagetsi kana maseketi kubva mukukuvadzwa.Nekudaro, muparadzi wedunhu haagone kuwana "yekuchengetedza-yemahara".Mune zvimwe zviitiko, kumwe kuchengetedza kuchiri kudiwa.
1. Kana rwendo rwekupfuura ruchiitika panguva yekushanda kwemutsigiri wedunhu, tarisa kana zvimwe midziyo yemagetsi iri mumamiriro ekushanda akanaka;
2. Tarisa kushanda kwechidziviriro chekudzivirira, uye inofanira kushanda pasi pemamiriro ekushanda;
3. Apo kushandiswa kwemagetsi kwemagetsi kunokundikana, chengetedza kuwirirana pakati pemagetsi ekushanda kwemagetsi uye muchengeti wedunhu;
4. Kana kukanganisa kwenguva pfupi kunoitika mumutsara, magetsi anofanira kubviswa;
5. Pamusana pekuchembera kwemukati wekuvharidzirwa kwemugadziri wedunhu mushure mekushanda kwenguva refu.Nokudaro, muparadzi wedunhu anofanira kugara achichengetwa.
Zvekungwaririra
1. Nzira yekushanda inofanira kuva yakavimbika kudzivirira njodzi.Panofanira kuva nezviratidzo zvakajeka zvinoratidzira uye zviito zvechiito chechikamu chimwe nechimwe mumagetsi, uye kusashanda kunofanira kudzivirirwa.
2. Kune redunhu rinoputika riri kushanda, kunyangwe mubato waro uri mukugumburwa, arcing inogona kuramba ichiitika mumatanho kana mumaseketi ekuvhura nekuvhara.Kuchengetedza kunofanira kutorwa kudzivirira misoperation panguva yekushanda.
3. Apo mhepo inoputika inoshanda (kunyanya kana ichicheka ikozvino huru), haigoni kudhonzwa nechisimba, kuitira kuti irege kukuvadza zvikamu zvemagetsi.
4. Mutsigiri wedunhu anofanirwa kugara achitarisa kuvhura kwayo uye kuvhara mamiriro ekusangana kuti adzivise overvoltage kana undervoltage kukanganisa.
5. Kana rwendo rwakakanganisa rukaitika, edza kudzoreredza magetsi akadzimwa kutanga.
