Ka bokhutšoanyane tsebisa tsena ka ts'ireletso e kholo ea transformer, 'me u tsoele pele ho hlahisa tšireletso ea backup ea transformer. Hona le mefuta e mengata ea ts'ireletso ea backup bakeng sa li-transform. Mona ke kenyelletso e khuts'oane ea mefuta e 'meli ea ts'ireletso ea ts'ireletso, ts'ireletso e fetelletseng le ts'ireletso ea mochini oa transformer.
1. Ts'ireletso e fetelletseng ka khatello ea senotlolo
2. Tšireletso e matla ea transformer
Ts'ireletso ea backup bakeng sa ho theha liphoso tsa potoloho e khuts'oane ea li-transformer tse kholo le tse mahareng hangata e kenyelletsa: zero sequence overcurrent protection, zero sequence overvoltage voltage, gap protection, joalo-joalo ntlha.
(1) Ntlha e sa jeleng paate e thehiloe ka kotloloho
(2) Ntlha e sa nke lehlakore ha e a thehwa
(3) Ntlha e sa jeleng paate e thehiloe ka lekhalo la ho tsoa
Li-transformer tse nang le motlakase o phahameng ka ho fetesisa kaofela ke li-transformer tse sa keneng mochesong, 'me kobo ea mobu ea ntlha e sa nke lehlakore e fokola ho feta likarolo tse ling. Ho se nke lehlakore ha lintlha ho senyeha habonolo. Ka hona, ts'ireletso ea lekhalo e hloka ho hlophisoa.
Mosebetsi oa ts'ireletso ea lekhalo ke ho sireletsa polokeho ea ts'ireletso ea ntlha e sa jeleng paate ea ntlha e sa kenelleng ea lehlakore ea transformer.
Ts'ireletso ea lekhalo e bonoa ka ho sebelisa lekhalo la hajoale la 3I0 le phallang ntlheng e sa jeleng paate ea transformer le volta e bulehileng ea delta 3U0 ea busbar PT e le moelelo.
Haeba ntlha e sa nke lehlakore ea phoso e nyolohela sebakeng seo, lekhalo lea senyeha 'me ho hlahisoe lekhalo le leholo la hona joale la 3I0. Ka nako ena, ts'ireletso ea lekhalo e se e buletsoe 'me sesebelisoa se ka emisoa kamora ho lieha. Ntle le moo, ha phoso ea fatše e hlaha tsamaisong, ntlha e sa jeleng paate e thehiloe mme ts'ireletso ea zero e latellanang e sebelisoa, mme ntlha e sa nke lehlakore e thehiloe pele. Kamora hore sistimi e lahleheloe ke motheo, haeba phoso e ntse e le teng, motlakase o bulehileng oa delta 3U0 ea busbar PT e tla ba kholo haholo, mme tšireletso ea lekhalo le eona e tla sebetsa ka nako ena.
