Efficient power supply, as solid as a rock—Three-phase pad-mounted transformers, your trusted power partner!

01 General

1.1 Project Description

This 1000 kVA Pad mounted transformer was delivered to Jamaica in 2024. The rated power of the transformer is 1000 kVA, with the primary voltage 13.8D kV to secondary voltage 0.415y/0.24 kV. The connection group is Dyn1, pad mounted transformer is a set of high-voltage control, protection, power transformation, and distribution equipment in one of the complete sets of pre-installed products, widely used in urban and rural distribution networks. The product places the high-voltage load switch and high-voltage fuse in the transformer oil, and has two structural forms of co-box or separate box with the transformer body. The oil tank is fully sealed and equipped with oil temperature gauge, oil level gauge, pressure gauge, pressure relief valve, oil relief valve and other components to monitor the operation of the transformer. The product is divided into ring network type, terminal type and power supply mode. Applicable to factories, mines, oil fields, ports, airports, urban public buildings, residential areas, highways, underground facilities and other places.

02 Manufacturing

2.1 Core

The core of the three-phase three-column transformer is composed of 6 pieces per layer, and the combination of the punch of each two layers applies different arrangements to stagger the joints of the magnetic circuit of each layer. This assembly method is called overlapping assembly, and this assembly can avoid the circulation of eddy currents between the steel sheet and the steel sheet. And because each layer of punching is interwoven, fewer fasteners can be used to make the structure simple when pressing the iron core. During assembly, the punching plates are first stacked to form a whole iron core, and then the lower iron yoke is clamped, the upper iron yoke punching plate is removed to expose the core column, the prefabricated winding is placed on the core column, and finally the extracted upper iron yoke punching plate is inserted.

2.2 Winding

Dyn1 connection is a common connection method in transformers, which mainly refers to the use of star (Y) connection to connect low-voltage windings and triangle (Δ) connection to connect high-voltage windings in three-phase transformers, and the phase of the low-voltage side lags behind the high-voltage side by 1 phase Angle (120°). In the Dyn1 connection, the phase of the low pressure side lags behind the high pressure side by 1 phase Angle (120°). This phase relationship helps to achieve better load balance in the three-phase load and reduce the problems caused by phase asymmetry. Because the star connection can provide a certain neutral point, Dyn1 connection can effectively suppress some harmonics, especially the third harmonic, so as to improve the power quality of the system. The neutral point of the star connection can be grounded, which can improve the safety of the system and provide better protection for equipment and personnel. In addition, equipment is better protected from damage in the event of a ground fault. The Dyn1 connection is suitable for many load types, including linear and nonlinear loads. This connection mode can also maintain good operating performance under unbalanced load conditions. Allows a variety of voltage conversion ratios, so that Dyn1 connection can be flexibly changed in different applications to adapt to different voltage requirements.

2.3 Tank

The box can adopt anti-corrosion design and special spray painting treatment according to the requirements of the operating environment, with “three anti-condensation” function, that is, anti-salt spray, anti-mold function, and can meet the anti-corrosion requirements in high temperature and high humidity environment. Fully sealed tank, fully insulated design, safe and reliable operation.

2.4 Final Assembly

Electrical Connections: Complete the internal connections for high-voltage and low-voltage cables, ensuring correct wiring between phases. Cooling System Inspection: Check the oil level and the components of the cooling system to ensure they are functioning properly. Insulation Testing: Perform insulation tests to ensure the electrical connections meet safety standards for insulation performance. Enclosure Sealing: Seal the transformer enclosure, ensuring all joints and seals are intact to prevent moisture and contaminants from entering.
