The RESIBLOC® transformer design with glass fiber reinforcement has proven itself well for networks with a voltage of 6-10-35 kV, has an extremely high reliability and complies with IEC 60076-11 and GOST R. Main technical parameters: Power from 250 to 40,000 kVA Voltage up to 45 kV Classification according to IEC 60076511 : for climatic conditions C2 environmental conditions E2 for fire safety F1 RESIBLOC® transformer technical solution : Glass fiber reinforcement completely eliminates the risk of cracking and provides the highest mechanical strength. Thermal protection even at the highest and lowest temperatures. Smooth surface prevents dust accumulation. Fiberglass and epoxy insulation prevents moisture penetration and provides protection in aggressive environments. Resistant to high voltage impulses due to the layered construction of the winding, providing a linear voltage distribution. Компактная обмотка с самофиксацией в виде единого блока дает оптимальную устойчивость к динамическим силам, возникающим при коротких замыканиях. Циллиндрические вентиляционные каналы позволяют обмотке охлаждаться естественным способом. Алюминиевая или медная фольга в обмотке низкого напряжения. Устойчивость при коротких замыканиях обеспечивается обмоткой низкого напряжения из фольги с использованием пропитанного стекловолокна в качестве изоляции. Самозатухание в случае воздействия внешнего пламени или электрической дуги, при этом не выделяются опасные газы. Технические характеристики трансформаторов RESIBLOC®: RESIBLOC® transformers are available for rated voltages up to 45 kV. High voltage windings can be supplied in versions for connection to networks of various voltages. Taps Standard tap ± 2 x 2.5%. Other branches can also be supplied on request. Short-circuit voltage For transformers with a short-circuit voltage different from the standard specified in the table on page 18, the value of the short-circuit voltage must be specified in the request. Groups of winding connections Standard version - D / Yн-5 or D / Yн-11. Other groups are available on request. Temperature rise (temperature mode) RESIBLOC® transformers are designed in accordance with the requirements of class F, allowing a temperature rise not exceeding 100 ° K, in accordance with IEC 60076-11 and VDE 0532. Sound levels Sound levels are presented as sound pressure levels in the table on page 18. All these levels apply for measurements at a distance of 1 m from transformers without enclosure, in version IP 00. Permissible deviations in accordance with IEC Losses: total losses + 10% of total losses; losses in no-load mode and in operation under load + 15% in idle mode and under load, provided that the level of total losses does not exceed the permissible limit. Transformation ratio deviation. The nominal deviation of the transformation ratio on the main branch must be less than the following values: ± 0.5% of the set nominal value; percentage of the intended transformation ratio, which is ± 1/10 of the measured rated short-circuit voltage. The transformation ratio for other branches is ± 1% unless otherwise specified. Short-circuit voltage at rated current on main branch ± 10% of rated value. Short-circuit voltage for other taps ± 15% of the agreed value for this taps. No-load current + 30% of no-load current. 60 Hz transformer Transformers designed to operate on a 50 Hz network can also be operated on a 60 Hz network. In this case, you should adjust the technical parameters as follows: Power (approx): 97% No-load loss: 80-85% Load losses (approx): 105% Short circuit voltage: 115-120% In this section: High-voltage bushings Components of transformers RPN Distribution transformers Diesel Generators Hyundai Site search home About company Products Articles Order Contacts Copyright 2011-2014 AMN Ltd.
