Asosiy transformator differensialligi va moyli transformatorlarning gazdan himoyasi o’rtasidagi farqlar qanday?

1. Yog ‘transformatorining asosiy transformatorining differentsial himoyasi aylanma tok printsipi bo’yicha ishlab chiqilgan va ishlab chiqarilgan, gaz muhofazasi esa ichki nosozlik natijasida gaz hosil bo’lishi yoki parchalanishi xarakteristikasiga muvofiq ishlab chiqilgan va ishlab chiqarilgan. transformator sodir bo’ladi.

Asosiy transformator differensialligi va moyli transformatorlarning gazdan himoyasi o’rtasidagi farqlar qanday?-SPL- power transformer, distribution transformer, oil immersed transformer, dry type transformer, cast coil transformer, ground mounted transformer, resin insulated transformer, oil cooled transformer, substation transformer, switchgear

2. Yog ‘transformatorining differentsial himoyasi transformatorning asosiy himoyasi, gaz muhofazasi esa transformatorning ichki xatosidan asosiy himoya hisoblanadi.

3. Yog’li transformatorlarni himoya qilish doirasi har xil:

3.1 Yog’li transformatorning differentsial himoyasi:

1) Ko’p fazali qisqa tutashuv transformatorning asosiy simi va transformator lasanida sodir bo’ladi.

2) Bir fazali jiddiy burilishlararo qisqa tutashuv.

3) Yuqori oqimdagi topraklama tizimidagi lasan va qo’rg’oshin simining topraklama xatosidan himoya qiling.

3.2 Yog’li transformatorlarni gazdan himoya qilish:

1) Transformator ichidagi ko’p fazali qisqa tutashuv.

2) burilishlararo qisqa tutashuv, burilishlararo va temir yadro yoki tashqi va qisqa tutashuv.

3) Temir yadrosining buzilishi (isitish va yonish).

4) Yog ‘darajasi ostida yog’ oqadi yoki oqadi.

5) Kranni almashtirgichning yomon aloqasi yoki simli payvandlashning yomonligi.
