Carane milih trafo daya tengen?

Pilihan trafo umume kudu dipikirake kanthi komprehensif saka aspek kapasitas trafo, tegangan, arus lan kahanan lingkungan. Antarane wong-wong mau, pilihan kapasitas kudu adhedhasar kapasitas, sifat lan wektu panggunaan peralatan listrik pangguna kanggo nemtokake beban sing dibutuhake, supaya bisa milih kapasitas trafo. Sajrone operasi normal, beban daya trafo kudu kira-kira 75% nganti 90% saka kapasitas trafo sing dirating.

Yen beban nyata saka trafo kurang saka 50% sajrone operasi, trafo kapasitas cilik kudu diganti, lan yen luwih gedhe tinimbang kapasitas trafo, trafo gedhe kudu langsung diganti. Ing wektu sing padha, nalika milih trafo, nilai voltase nduwurke tumpukan utami trafo kudu ditemtokake miturut garis sumber daya, lan nilai voltase nduwurke tumpukan sekunder kudu dipilih miturut peralatan listrik. kanggo milih sumber daya papat-kabel telung fase kurang voltase. Bisa nyedhiyakake daya lan daya cahya ing wektu sing padha.

Nalika kita biasane milih trafo distribusi, yen kapasitas gedhe banget, kedadean saka “troli jaran-digambar amba” bakal kawangun, kang ora mung nambah investasi peralatan, nanging uga tansah trafo ing negara tanpa mbukak kanggo a dangu. . , nambah mundhut daya reaktif; yen kapasitas trafo cilik banget, trafo bakal ing negara overloaded kanggo dangu, lan trafo bakal diobong metu gampang, apa iku autotransformer utawa telung phase trafo, iku padha. Mula, milih kapasitas trafo sing tepat minangka salah sawijining langkah penting kanggo nyuda kerugian lan ngirit energi ing jaringan listrik.

menyang cara prasaja ing ngisor iki.

Langkah:

1. Nalika kita biasane milih trafo distribusi, yen kapasitas gedhe banget, fenomena “troli jaran-digambar amba” bakal kawangun, kang ora mung nambah investasi peralatan, nanging uga tansah trafo ing kondisi ora mbukak kanggo wes suwi. dawa Yen kapasitas trafo cilik banget, trafo bakal ing negara overloaded kanggo dangu, lan iku gampang kanggo ngobong metu trafo, apa iku autotransformer utawa trafo telung phase, iku padha. Mula, milih kapasitas trafo sing tepat minangka salah sawijining langkah penting kanggo nyuda kerugian lan ngirit energi ing jaringan listrik. Ing aplikasi praktis, kita bisa milih kapasitas trafo miturut cara prasaja ing ngisor iki.

2. Prinsip “kapasitas cilik, distribusi padhet” kudu dipatuhi. Transformator distribusi kudu diselehake ing tengah beban sabisa, lan radius sumber daya ora ngluwihi 0.5 kilometer. Tingkat beban trafo distribusi paling dhuwur antarane 0.5 lan 0.6, lan kapasitas trafo saiki diarani kapasitas ekonomi. Nanging, yen beban relatif stabil, kapasitas trafo bisa dipilih miturut kapasitas ekonomi ing syarat-syarat produksi terus.

3. Miturut karakteristik pangguna kothak daya deso kasebar, Kapadhetan mbukak kurang, kuwat mangsan lan mbukak kuat intermiten, etc, trafo imbuhan kapasitas bisa digunakake. Transformator pangaturan kapasitas minangka trafo sing bisa nyetel kapasitas tanpa beban miturut ukuran beban, cocog kanggo digunakake ing papan sing owah-owahan musiman ing beban katon jelas. Kanggo gardu utawa perusahaan industri lan pertambangan kanthi beban daya gedhe, trafo utama lan tambahan umume digunakake kanggo sumber daya, siji (ibu) dikonfigurasi miturut beban maksimal, lan liyane (sekunder) dipilih miturut kahanan beban sing sithik. , sing bisa ningkatake distribusi daya. Pemanfaatan trafo, nyuda kerugian trafo distribusi tanpa mbukak. Amarga kasunyatan manawa sawetara trafo distribusi ing wilayah deso ana ing operasi kurang beban kanggo wektu sing suwe, kajaba sawetara beban listrik puncak ing setahun, kanggo pangguna sing duwe kahanan, trafo ibu-anak utawa trafo daya operasi paralel. mode sumber uga bisa digunakake. Nalika beban diganti banget, miturut prinsip mundhut daya paling, sijine iku ing trafo karo kapasitas beda. Kanggo trafo khusus sing mung nyuplai daya kanggo beban daya kayata irigasi lan got, kapasitas trafo umume bisa dipilih miturut 1.2 kaping daya nameplate motor asinkron. Umumé, motor wiwitan saiki papat nganti kaping pitu saiki dirating, lan trafo kudu bisa nahan impact iki. Kapasitas salah siji saka Motors paling gedhe miwiti langsung ngirim umume ora ngluwihi bab 30% saka kapasitas trafo. Perlu dicathet yen trafo khusus kanggo saluran banyu lan irigasi umume ora kudu disambungake karo beban liyane, saéngga mandheg operasi ing wektu sajrone wektu sing ora saluran lan irigasi lan nyuda kerugian energi listrik.
