Sebakeng sa boenjiniere ba motlakase, li-transformer li bapala karolo ea bohlokoa phetisong le kabong ea matla a motlakase. Har'a mefuta e sa tšoaneng ea li-transformer, li-transformer tsa hona joale (CTs) le li-transformer tsa matla (PTs) ke tse peli tse sebelisoang ka ho fetisisa. Ho sa tsotellehe mabitso a bona a tšoanang, ba sebeletsa merero e fapaneng 'me ba bohlokoa likarolong tse fapaneng tsa tsamaiso ea motlakase. Sehlooho sena se hlahloba hore na li-transformer tsa hona joale le li-transformer tsa motlakase li sebelisetsoa eng, 'me li totobatsa morero o ka sehloohong oa motlakase oa hona joale.
Ke eng aTransformer ea hajoale?
Transformer ea hajoale ke mofuta oa sesebelisoa sa sesebelisoa se etselitsoeng ho lekanya hona joale (AC). E sebetsa ka ho hlahisa hona joale e fokolitsoeng ka nepo e lekanang le ea hona joale potolohong, eo ka nako eo e ka hlahlojoang ka mokhoa o sireletsehileng le ho lekanyetsoa ka lisebelisoa tse tloaelehileng. Li-CT li bohlokoa maemong ao maemo a hona joale a leng holimo haholo hoo a ke keng a lekanngoa ka ho toba ka lisebelisoa tse tloaelehileng.
Sepheo se seholo sa Transformer ea Hona Joale
Sepheo sa mantlha sa transformer ea hona joale ke ho nolofatsa tekanyo e sireletsehileng le ho beha leihlo maemo a phahameng a hona joale. Ka ho theola hona joale ho ea boemong bo tlaase, bo laolehang haholoanyane, CTs e lumella ho sebelisa lisebelisoa tse tloaelehileng tsa ho lekanya le li-relay tse sireletsang. Sena ke sa bohlokoa ka lebaka la mabaka a latelang:
Tšireletseho:Ho lekanya maqhubu a phahameng ka ho toba ho ka ba kotsi. CTs e fokotsa hona joale ho ea boemong bo sireletsehileng, ho fokotsa kotsi ho basebetsi le lisebelisoa.
Ho nepahala:Li-CT li fana ka litekanyo tse nepahetseng tsa hajoale, tse bohlokoa bakeng sa ts'ebetso e nepahetseng ea li-relay tse sireletsang le lisebelisoa tsa metering.
Ho behwa ka thoko:Ba fana ka karohano ea motlakase pakeng tsa potoloho ea matla a matla a phahameng le lisebelisoa tsa ho lekanya, ho sireletsa tse qetellang ho tloha ho matla a phahameng a matla.
Lisebelisoa tsa li-Current Transformers
Li-transformer tsa hona joaleli sebelisoa haholo lits'ebetsong tse fapaneng, ho kenyelletsa:
Tšireletso ea Sisteme ea Matla:Li-CTs li bohlokoa ts'ebetsong ea li-relay tse sireletsang, tse bonang liphoso le ho qala li-circuit breakers ho arola likarolo tse fosahetseng.
Metara:Li sebelisoa ho metha ea matla ho lekanya boholo ba matla a motlakase a sebelisitsoeng.
Tlhokomelo:Li-CTs li thusa ho lekola phallo ea hona joale lits'ebetsong tsa matla, ho thusa ho lemoha meroalo e mengata le ho netefatsa phepelo e nepahetseng ea matla.
Ke eng aTransformer ea matla?
Ka lehlakoreng le leng, transformer ea matla e etselitsoe ho fetisetsa matla a motlakase lipakeng tsa lipotoloho tse peli kapa ho feta ka induction ea motlakase. Li-transformer tsa motlakase li sebelisetsoa ho phahamisa (ho eketsa) kapa ho theola (fokotsa) maemo a motlakase litsamaisong tsa motlakase, ho thusa phetiso e nepahetseng le kabo ea matla a motlakase libakeng tse telele.
Morero o ka Sehloohong oa Transformer ea Matla
Morero o ka sehloohong oa transfoma ea motlakase ke ho etsa hore phetiso e sebetsang ea motlakase ho tloha liteisheneng tsa ho fehla motlakase ho ea ho basebelisi ba ho qetela. Sena se kenyelletsa:
Taolo ea Voltage: Li-transformer tsa motlakase li fetola maemo a motlakase ho fokotsa tahlehelo ea matla nakong ea phetisetso. Li-voltage tse phahameng li sebelisoa bakeng sa phetisetso ea sebaka se selelele ho fokotsa hona joale, ka lebaka leo, tahlehelo ea ho hanyetsa.
Kabo ea Meroalo: Ba thusa ho tsamaisa meroalo ea motlakase ho potoloha lipotoloho tse fapaneng, ho netefatsa phepelo ea motlakase e leka-lekaneng le e tsitsitseng.
Ho itšehla thajana: Li-transformer tsa motlakase li fana ka karohano ea motlakase lipakeng tsa likarolo tse fapaneng tsa sistimi ea matla, ho matlafatsa polokeho le ts'epahalo.
Lisebelisoa tsa Power Transformers
Li-transformer tsa matlali bohlokoa methating e fapaneng ea ketane ea phepelo ea motlakase, ho kenyelletsa:
Liteishene tsa Meloko: Li eketsa matla a motlakase a hlahisoang ke lifeme tsa motlakase bakeng sa phetiso e sebetsang hantle ea sebaka se selelele.
Lisebelisoa: Li-transformer tse liteisheneng tse nyane li theola matla a phahameng a phepelo ea motlakase ho theola maemo a loketseng ho abeloa malapeng le likhoebong.
Lisebelisoa tsa Indasteri: Li sebelisoa maemong a indasteri ho fana ka maemo a hlokahalang a motlakase bakeng sa mechini le lisebelisoa tse fapaneng.
Qetello
Ka kakaretso, li-transformer tsa hajoale le li-transformer tsa motlakase li sebetsa mesebetsi e fapaneng empa e le tlatsetso lits'ebetsong tsa motlakase. Li-transformer tsa morao-rao li sebelisoa haholo-holo bakeng sa ho lekanya le ho shebella maemo a phahameng a hona joale ka mokhoa o sireletsehileng le ka mokhoa o nepahetseng, ha li-transformer tsa motlakase li le bohlokoa bakeng sa ho fetisa le ho aba matla a motlakase hantle. Ho utloisisa mesebetsi le ts'ebeliso ea li-transformer tsena ho bohlokoa ho mang kapa mang ea amehang lefapheng la boenjiniere ba motlakase.
