General zvinodiwa pakuvhara magetsi

Interlocks uye DCS switches haigone kushandiswa kupatsanura simba remagetsi.Maswichi anoshandiswa kutyaira maseketi ekudzora mota/relays (eg pombi on/off mabhatani) haatenderwe kushandiswa kupatsanura simba remagetsi.Kunze kwemutemo uyu kana mugadziri wemagetsi anoda kumisa pombi pakakiyiwa on/off bhatani asati adimbura switch yemagetsi muimba yeMCC.

Kana kuvharika kwemagetsi kuchidikanwa, mushandi mukuru ane mvumo anofanira kuita zvinotevera: bvunza mugadziri wemagetsi anokwanisa kuti abvise switch inoenderana (kana redunhu breaker).Nyanzvi yemagetsi inoiburitsa.Mugadziri wemagetsi haafanire kubvisa fuse kana mushandi wenzvimbo asiri panzvimbo yekusimbisa nzvimbo yakakodzera yekudimburira uye kuratidza kuti mudziyo wakadzimwa.

Iyo fuse yakabviswa inofanira kuiswa mu fuse pack, yakaputirwa nekiyi uye yakavharwa kune disconnect switch handle.The collective lock uyeLockout tagakakiyiwa pa disconnect switch handle.Bvisa kiyi pamudziyo tanga switch, edza kutanga mudziyo nekutanga switch, uye kiya switch.

Kana nyanzvi yemagetsi ichida kuita mamwe mabasa pane kungoburitsa fuse, inofanirwa kuita zvinotevera zvinodiwa:

Zvishandiso zviri pamusoro pe480 VOLTS: Makiyi emunhu anofanirwa kusungirirwa pamagetsi anodimburwa kana vashandi vemagetsi vari kushanda pamidziyo.

Bvisa uye isa waya chero ipi zvayo yemagetsi: Makiyi emunhu anofanirwa kusungirirwa pamidziyo inobvisa magetsi kana vashandi vemagetsi vari kushanda pamidziyo.

Kune chero chekushanda pamusoro apa, mushandi anonyanya kupihwa mvumo yekushandisa lock block lock uyeLockout tagpa disconnect device.

Vagadziri vemagetsi vanoisa yakakoshaLockout tagskubvisa midziyo yekutsanangura chero basa kunze kwekuburitsa fuse.Iyo tegi inoramba iri pamudziyo wakadzimwa kusvika yagadzirira kushandiswa zvakare uye inogona kubviswa chete neanogadzira magetsi.Kana imwe nguva basa remagetsi rapera, mugadziri wemagetsi anogona kubvisa kuvhara kubva pamudziyo wekubvisa.Cherechedza: Mameseji akakosha eseLockout tagsinogona kubviswa chete kana mabasa ese apera.
