Tendering & Design Calculation Softwares
Tender Calculation: This involves determining the optimal design based on the capitalization price.
The selection of transformer variants is based on various economic criteria, including capitalized value and material costs. These variants are carefully compared by considering several key factors, such as limits on paired impedance, potential losses, masses, and transportation dimensions. The program is designed to streamline this process by enabling the simultaneous selection of transformer variants, even with multiple impedance restrictions. This thorough approach ensures that the most cost-effective and efficient transformer variants are chosen, meeting all specified requirements.
Magnetic system construction types are 1/2, 2/0, 2/2, 3/0, and 3/2. The first digit shows the number of legs with windings, while the second digit indicates the number of side yokes. These configurations highlight the careful design and engineering of an efficient magnetic system.
Design Calculation: General-purpose power and autotransformers and fixed or variable shunt reactors 2.5 – 1000 MVA, 10 – 1100 kV.
All windings are round in shape and arranged concentrically on the leg. Each winding may consist of one or several concentric parts (concenters) connected in series.
The wires, made from electrical copper or aluminum, include:
Simple
Paper-insulated subdivided
Enamel-insulated transposed
Voltage regulation is a critical aspect of transformer design and operation. There are three primary types of voltage regulation:
On-load tap-changer (OLTC)
No-load tap-changer (NLTC)
Without regulation
Cooling types for transformers encompass various methods including ONAN (Oil Natural Air Natural), ONAF (Oil Natural Air Forced), OFAF (Oil Forced Air Forced), OFWF (Oil Forced Water Forced), ODAF (Oil Directed Air Forced), and ODWF (Oil Directed Water Forced). Specifically, in ODAF and ODWF cooling systems, the oil supply and its directed circulation within the windings' axial ducts are constructively ensured to enhance cooling efficiency.
