Joriy transformatorlardan foydalanish

1) 1 sim ning tellari oqim transformatori follow series printsipi: bo'lsa 2c birlamchi shamollatish bo'lishi kerak ketma-ket bog'langan yo'l ostida sinov, while ikkilamchi shamollatish kerak ulangan barcha asbob yuklari bilan ulangan bo'lishi kerak.

2) Mos o'zgarish ga mos o'zgarish ko'ra ning magnitudasi o'lchanadigan oqim, aks holda xato ko'payadi. At the the same time, one end of the secondary side must ground oldini olish uchun oldini olish uchun yuqori voltaj on the birlamchi yon yon dan kirish uchun past voltage yon yon of of the secondary side bir marta bo'lsa izolyatsiya shikastlangan, sabab shaxsiy va asbob-uskunalar avariyalari

3) Ikkilamchi tomon mutlaqo yo'l qo'yilmaydi ochiladi. Bir marta tuman ochiladi 2c the primary side current I1 the magnetizing current, resulting a sudden increase in φm and E2, natijada haddan tashqari to'yingan va magnitlanish ning temir yadrosi 2c jiddiy isitish va hatto yonib yonish uchun coil; at the time, the over-to'yinganligi va magnitizatsiya ning magnitlashtirish miqdori o'sadi xato ko'payadi . qachon oqim transformatori ishlayotganda normal, the secondary side is taxminan qisqa-tuman bo'ladi. Agar u to'satdan ochilgan, the excitation electromo to'satdan kuch o'zgaradi a a kichik qiymat dan a a katta qiymat, va magnit oqim ichida temir kon presents a qattiq to'yingan tekis tepada. To'lqin, shunda ikkilamchi yon shamollatish induktsiya a yuqori cho'qqi to'lqin o'tganda magnit maydon orqali nol, va uning dir qiymat ming ming yoki hatto o'n ming volt volt, xavf tug'dirishi mumkin ishchilarning xavfsizligi va izolyatsiya ishlashi asbob asbobining ishlashi .

Bundan tashqari, ochiq tuman of the primary side causes the voltage of the secondary side to reach to hundreds of volts, bu sabab elektr shok hodisalari bir marta tegadi. Shuning uchun, ning ikkilamchi tomoni yon 2c 2c 2c 2c ni to'ldiradi oqim transformator bilan jihozlangan bilan jihozlangan a qisqa-tuman o'tish oldini olish oldini olish uchun oldini olish uchun birlamchi yon yon ochiq bo'lishdan ochiq. foydalanish davomida foydalanish davomida, marta bir marta ikkilamchi yon ochiq, bo'ladi tuman yuk kerak darhol olib tashlash 2c va keyin to'xtash kerak to'xtash kerak 2c va to'xtash uchun to'xtash kerak mashina. U mumkin qayta foydalanish keyin hamma ishlanadi.

4) In order to meet the needs of measuring instruments, relay protection, circuit breaker failure judgment and fault filtering, etc., install 2 to 8 current transformers with secondary amp shamollatishlar. For katta-oqim yerto'ldiruvchi tizimlar, u umuman moslashtirilgan as uch faza; uchun kichik-oqim yerto'ldirilish tizimlari, u moslashtirilgan ikki-faza yoki uch-faza mos talablarga ko'ra aniq talablarga ko'ra

5) The o'rnatish joylashuv of the himoya oqim transformator bo'lishi kerak yo'q yo'q uchun himoyalanmagan maydoni of the main himoya qurilma iloji boricha ko'p mumkin. Misol uchun 3a agar mavjud ikkita bo'lsa mavjud oqim transformatorlar to'plamlari to'plamlari, va joy ruxsatnomalar, ular o'rnatilgan bo'lishi kerak ikkala tomon ikkala tomon ning ikkala tomoni da tuman buzuvchi, shunda ki tuman buzuvchi ichida bo'ladi da bo'ladi xoch himoyasi oralig'ida bo'ladi

6) In order to prevent the bus fault by the flashover of the bushing of the pillar current transformer, the current transformer is odatda on the outgoing line of the circuit breaker or on on the side of the transformer

7) In order to reduce the damage by the the internal failure of the generator, the current transformer used to automatically adjust the the excitation device should arranged of the outlet side of the generator stator shamollatish. In tartibida to oson tahlil va topish ichki xatarlar oldin generator integratsiya qilinadi tizim 2c uchun o'lchash asboblari uchun ishlatiladigan o'lchash asboblari uchun o'rnatilgan bo'lishi kerak neytral nuqta tomoni yon tomon of the the 1 of the g 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5 bo'lishi kerak generator.
