Tartar da Noma da Karamin Rike da Karamin Rike a Tashar Karamin Rike

Sunan noma:
Idan za a yi noma, kafin ya fara karamin rike (LV) tana fara karamin rike (HV).

• Idan za a yi noma na LV:
  Kafin ya fara karamin rike, kafin ya fara karamin rike na LV na farko, sannan kafin ya fara karamin rike na LV na yamma. Kuma kafin ya fara karamin rike, kafin ya fara karamin rike na cikakken kontrola, sannan kafin ya fara karamin rike na yamma.

• Idan za a yi noma na HV:
  Kafin ya fara karamin rike, kafin ya fara karamin rike na HV, sannan kafin ya fara karamin rike na disconnector.
  Idan anka ta HV tana da disconnector biyu, kafin ya fara karamin rike na disconnector na yanke, sannan kafin ya fara karamin rike na disconnector na masu sauri.

Sunan karamin rike: Tsarin sunan noma tana zama tsarin karamin rike.

Ba a yi amfani da disconnector idan akwai karamin rike.

Tsarin Karamin Rike Don Tashar Karamin Rike

Tsarin karamin rike shi ne:

• Tabbatar da ba a gudanar da wani mutum a yi aiki a kan karamin rike daban-daban a tashar karamin rike. Kafin ya fara karamin rike, kafin ya fara karamin rike na kayan grounding, sannan kafin ya fara karamin rike na kayan alamun. Idan za a fara karamin rike na grounding, kafin ya fara karamin rike na yanke, sannan kafin ya fara karamin rike na yamma.

• Duk da a duba cewa karamin rike na WL1 da WL2 suka fara karamin rike. Sannan kafin ya fara karamin rike na bus-tie disconnector bayan WB1 da WB2 don haka za su iya yi aiki a kan biyu.

• Kafin ya fara karamin rike na disconnector biyu a WL1, sannan kafin ya fara karamin rike na circuit breaker na WL1. Idan an samu nasara, yana nufin cewa WB1 da WB2 suka fi sani.

• Kafin ya fara karamin rike na disconnector na VT circuits bayan WB1 da WB2, sannan duba cewa karamin rike na supply yana daidai.

• Kafin ya fara karamin rike na disconnector biyu a HV, sannan kafin ya fara karamin rike na circuit breaker biyu a HV don karamin rike na main transformers a tashar karamin rike.

• Kafin ya fara karamin rike na knife switch na LV side na main transformer a Distribution Room No. 2, sannan kafin ya fara karamin rike na LV circuit breaker. Idan an samu nasara, yana nufin cewa LV busbar yana fi sani.

• Amfani da voltmeters na biyu a LV busbar don duba cewa karamin rike na LV yana daidai.

• Kafin ya fara karamin rike na knife switches biyu a LV a Distribution Room No. 2, sannan kafin ya fara karamin rike na LV circuit breakers (ko LV fuse-switch disconnectors) don karamin rike na LV outgoing circuits. A wannan lokacin, duk tashar HV distribution substation da workshop substations suka samu karamin rike.

Karamin Rike Bayan Samun Noma Da Sabon Noma

Idan za a yi karamin rike bayan samun noma da sabon noma, tsarin karamin rike yana da muhimmanci game da abin da aka amfani a kan incoming line:

• Idan anka ta incoming line an amfani high-voltage circuit breaker:
  Idan anka ta short-circuit fault a HV busbar, circuit breaker zai fara karamin rike mai zurfi. Bayan samun noma, za a iya karamin rike tare da reclosing circuit breaker.

• Idan anka ta incoming line an amfani high-voltage load-break switch:
  Bayan samun noma, kafin ya fara karamin rike na fuse cartridge, sannan kafin ya fara karamin rike na load-break switch don karamin rike.

• Idan anka ta incoming line an amfani high-voltage isolating switch with fuses (fuse-disconnector combination):
  Bayan samun noma, kafin ya fara karamin rike na fuse tube, sannan kafin ya fara karamin rike na outgoing circuit breakers. Sannan kafin ya fara karamin rike na isolating switch, sannan kafin ya fara karamin rike na outgoing breakers don karamin rike.

• Idan anka ta incoming line an amfani drop-out fuse (expulsion fuse):
  Abin da aka amfani shi ne—kafin ya fara karamin rike na fuse tube, tabbatar da outgoing switches suka fara karamin rike, sannan kafin ya fara karamin rike na fuse, sannan kafin ya fara karamin rike na outgoing circuits.
