LIEKETSENG LEFATŠE

Transformer ea lefats'e, eo hape e tsejoang e le "grounding transformer", ke mofuta oa transformer o sebelisetsoang ho theha khokahanyo ea lefats'e e sireletsang bakeng sa lisebelisoa tsa motlakase. E na le matsoelintsoeke a motlakase a hokahaneng le lefats'e mme a etselitsoe ho theha ntlha e sa nke lehlakore e thehiloeng.

Li-transformer tsa lefatše li bapala karolo ea bohlokoa polokehong ea motlakase. Li sebelisetsoa ho fokotsa kotsi ea ho tsosoa ha motlakase le ho sireletsa lisebelisoa ho tsoa tšenyo e bakoang ke mefokolo ea motlakase. Lits'ebetsong tsa motlakase moo ho se nang khokahanyo ea tlhaho ho lefats'e, joalo ka marang-rang a phetisetso ea motlakase o phahameng, ho kenngoe mochini oa lefatše ho fana ka khokahano e sireletsehileng le e tšepahalang ea motheo.

Li-transformer tsa Earthing li sebelisoa hangata ho li-transformer tsa matla, li-reactor unit le litsamaiso tsa motlakase. Li etselitsoe ho ba le karo-karolelano e tlase ho feta li-transformer tse tloaelehileng tsa matla, e leng se bolelang hore li ka khona ho jara motlakase o phahameng ntle le ho theha matla a phahameng. Karo-karolelano ea transformer ea earthing hangata e behiloe ho 1: 1, ho bolelang hore motlakase oa ho kenya letsoho le motlakase o tsoang lia tšoana.

Moetso oa li-transformer tsa lefatše o fapana ho latela ts'ebeliso le mofuta oa sistimi ea motlakase eo e sebelisoang ho eona. Li-transformer tse ling tsa lefatše li etselitsoe ho qoelisoa ka oli, ha tse ling e le li-transformer tsa mofuta o omileng. Khetho ea mofuta oa transformer le moralo o ipapisitse le litlhoko tse ikhethileng tsa sistimi ea motlakase.

Li-transformer tsa Earthing li boetse li sebelisoa lits'ebetsong tsa motlakase ho fokotsa ho feto-fetoha ha motlakase le ho tsamaisa boima ba 'mele. Li ka sebelisoa lits'ebetsong tsa motlakase moo ho nang le meroalo e sa leka-lekaneng kapa moo ho nang le phapang e kholo ea tlhoko ea mojaro.

Qetellong, li-transformer tsa lefats'e ke likarolo tsa bohlokoa lits'ebetsong tsa motlakase, tse fanang ka khokahano e sireletsehileng le e ka tšeptjoang ea motheo le ho sireletsa lisebelisoa tsa motlakase tšenyo e bakiloeng ke mefokolo ea motlakase. Moralo le ho kenya li-transformer tsa lefatše li ipapisitse le litlhoko tsa sistimi e ikhethileng ea motlakase, 'me li bapala karolo ea bohlokoa polokehong ea motlakase le botsitso ba sistimi.

Li-transformer tsa Earthing ke likarolo tsa bohlokoa tsamaisong ea matla a motlakase, e etselitsoeng ho netefatsa polokeho le ts'ebetso e tšepahalang ea sistimi. Li-transformer tsena li sebeletsa morero oa mantlha ka ho hokahanya ntlha e sa nke lehlakore ea marang-rang a mekhahlelo e meraro ea kabo ea matla lefatšeng. Mona ke lintlha tse ling tsa bohlokoa tsa li-earth transformer:

• Ho Theola Lehlakore: Ka tsamaiso ea matla a mekhahlelo e meraro, e 'ngoe ea li-conductors e khethiloe e le ntlha e sa nke lehlakore, eo hangata e hokahaneng le lefats'e ka mabaka a tšireletso. Transformer ea lefatše e sebelisoa ho theha khokahano ena. E etsa bonnete ba hore sebaka sa ho se nke lehlakore se teng kapa se haufi le lefatše.

• Ho behwa ka thoko: Li-transformer tsa Earthing li entsoe ka mokhoa o ikhethileng oa bobeli. Sena se bolela hore maqhubu a mantlha le a bobeli ha a kopane ka ho toba, a fana ka ho itšehla thajana ha motlakase pakeng tsa tsamaiso le fatše. Ho itšehla thajana ho bohlokoa bakeng sa polokeho le ho lemoha liphoso.

• Khatello ea Resonance: Litsamaisong tse ling tsa matla, maemo a resonance a ka hlaha ka lebaka la bokhoni ba mela e telele e holimo. Li-transformer tsa lefats'e li ka thusa ho fokotsa taba ena ka ho fana ka tsela e tlaase ea ho hanyetsa fatše, ho thibela ho feta le ho senya tsamaiso.

• Phoso Current Limiting: Li-transformer tsa Earthing li ka hlomelloa ka li-resistors tsa fatše ho fokotsa maqhubu a phoso nakong ea liphoso tsa fatše. Sena ha se sireletse feela tsamaiso ho tloha ho nako e feteletseng empa hape se thusa ho fumana le ho arola liphoso kapele.

• Mefuta ea li-Earthing Transformers: Ho na le mefuta e fapaneng ea li-transformer tsa lefats'e, ho kenyelletsa le li-transformer tse thehiloeng ka thata, tse thehileng le ho hanyetsa. Khetho ea mofuta o itšetlehile ka litlhoko tse khethehileng tsa tsamaiso ea matla le tekanyo ea tšireletso ea phoso e hlokahalang.

• Tšireletseho le Botšepehi: Ho thea ka nepo ka li-transformer tsa mobu ho matlafatsa polokeho ea lits'ebetso tsa motlakase ka ho fokotsa kotsi ea litšisinyeho tsa motlakase le mello. E boetse e thusa ho netefatsa ts'ebetso e tšepahalang ea litsamaiso tsa kabo ea motlakase ka ho thibela liphoso tsa mohato ho isa fatše le ho se leka-lekane ha motlakase.

• Tlhokomelo: Tlhokomelo ea kamehla le tlhahlobo ea li-transformer tsa lefatše li bohlokoa ho netefatsa ts'ebetso ea tsona e tsoelang pele ho fana ka tikoloho e bolokehileng le e tšepahalang ea motlakase.
