TM-400/6(10)/0,4 2) Suv chiqarish qurilmasi uchun
TM-160/6(10)/0,4.

Transformator tanlaymiz:
TДНС-16000\35-74У1
S= 16000 kVA
U_n=35kV
VN=38.5 kV
NN=10,5; 6.3kV
P_xx=58 kVt
R_k.z.= 280kVt
U_k.z.= 10 % ot U_nom = 3.67kV
I_k.z.= 0,45% ot I_nom = 0.76 A
= 16000/1.7*35 = 264 A
Avariya holatida qolishi mumkin bo’lgan transformator yuklamaning oshib ketishiga tekshirib ko’riladi, 2 darajali iste’molchilarni uchishini nazarga olgan holda
1,4S_HTS_p 1,4*16000 17126,3 22400 ₁_7126,3
Transformator avariya holatidagi tekshirishni o’tdi.
Tamomila ikkita transformator tanlaymiz ТДНС -16000 kVA.

SBSH-250MN ta’minlash

Iste’molchining quvvati katta bo’lganligi sababli PTPga bitta burg’illash uskunasini ulashga qaror qildik.

= (0,6 * 386*1)/ 0.7 = 330,86 kVA
Bu yerda:
k_{c.gr –}guruhning talab koeffitsienti.
Bizda PTP da bitta iste’molchi bo’lganligi sababli uning talab koeffitsientini olamiz.
R_{nomi -}guruhdagi iste’molchining nominal quvvati, kVt
cos - iste’molchilarning o’rtacha quvvati koeffitsient
cos = 0.7
Barcha SBSH-250MN ta’minlash uchun transformator tanlaymiz:

TM-400/6(10)/0,4

2) Suv chiqarish qurilmasi uchun (vodootlivnaya ustanovka)
= (0,8 * 410)/0.55 = 596,4 kVA
Barcha suv chiqarish qurilmasi uchun transformator tanlaymiz
TMН-1600/6(10)/0,4

Mexanik xizmat ko’rsatish qurilmasi uchun (mexanicheskaya masterskaya)

= (0,3 *200)/0.65 = 92,3 kVA
Mexanik xizmat ko’rsatish sexi uchun transformator tanlaymiz

TM-160/6(10)/0,4.
