Dowei Electric MV Transformer Station MTS-6300

Product catalog summary

General Description:

The MV Transformer Station adheres to international standards such as IEC 60076, IEC 62271, ANSI/IEEE Std C57, and NEMA, and is certified by ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA.
It uses mineral or vegetable oil (FR3) and is free of PCBs, designed for seismic conditions per ETGI-1.020 and IEEE Std 693.
The structural design complies with ASTM A325, ANSI/AISC 360, and AWS D1.1, with high altitude correction up to 5000m.
Features include eco-design for lower self-consumption, robust design for harsh environments, prefabricated container design, and real-time monitoring and remote control capabilities.

Typical Specification:

The station has a capacity of 6300kVA with an input AC power of 6,300 kVA at 40℃ and 5,760 kVA at 50℃.
It supports up to 36 inverters, with a rated input voltage of 800 V and a maximum input current of 2,428 A x 2.
Output voltage ranges from 10 kV to 35 kV, with frequency options of 50 Hz and 60 Hz.
The transformer is oil-immersed, conservator type, with a vector group of Dy11-y11 and transformer tappings of ± 2 x 2.5%.
Transformer load losses are 49.7 kW and 41 kW, with no-load losses of 4.8 kW and 5.8 kW.

Protection and Safety:

Includes oil level, temperature, pressure, and Buchholz monitoring and protection.
MV and LV rooms have a protection degree of IP 54, with internal arcing fault protection at 20 kA for 1 second.
Equipped with MV relay protection (50/51, 50N/51N) and surge arresters, along with LV overvoltage protection Type I+II.

General Features:

The dimensions are 6,058 x 2,896 x 2,438 mm, with a weight of less than 22 tons.
Operating temperature ranges from -25℃ to 60℃, with a relative humidity of 0% to 95% and a maximum operating altitude of 2,500 m.
Communication is facilitated through Modbus-RTU, preconfigured with Smartlogger3000B.

Components and Options:

Optional components include auxiliary transformers (50 kVA, Dyn11), 1.5 kVA UPS, updated MV switchgear, and interlocking features.
