10 kV Amorphous Alloy Oil-Immersed Transformer

1. Product Overview

The 10 kV amorphous alloy oil-immersed transformer is a high-efficiency energy-saving power distribution equipment optimized for medium-voltage power grid operation. Different from traditional silicon steel sheet transformers, this product adopts advanced iron-boron-based amorphous alloy strip as the core material, paired with mature oil-immersed heat dissipation and insulation structure, effectively solving the problems of high no-load loss and large energy consumption of conventional distribution transformers.

This series of transformers mainly includes SH15 and SH16 mainstream models, covering conventional capacity ranges from 30kVA to 2500kVA. It adopts a three-phase five-limb integral core structure, which simplifies the overall structural layout, reduces equipment height, and improves operational stability. With reliable oil-sealed fully enclosed design, the equipment can adapt to long-term continuous operation in various complex environments. Its load loss index is consistent with high-standard conventional transformers, while the no-load loss is reduced by more than 75% compared with traditional S9 series products, bringing significant long-term energy-saving benefits for power operation enterprises and industrial and commercial users.

2. Core Product Parameters

The following are the standard technical parameters of 10kV amorphous alloy oil-immersed transformer mainstream models, which comply with national power industry standards and international general power equipment specifications, and can support customized parameter adjustment according to user engineering needs.

3. Product Core Features

3.1 Ultra-low Energy Consumption

The amorphous alloy core has excellent soft magnetic properties and extremely low coercivity, which fundamentally reduces no-load magnetic loss and excitation power. Compared with traditional silicon steel sheet transformers, the no-load loss is reduced by over 75%, and no-load current is greatly decreased. For power distribution equipment that operates 24/7 all year round, it can save a large amount of invalid power consumption, with obvious energy-saving effects and short investment recovery cycle.

3.2 Stable and Reliable Operation

The three-phase five-limb integral core structure optimizes the magnetic circuit design, effectively suppresses harmonic flux and zero-sequence flux, reduces voltage drop and power grid fluctuation, and improves power supply quality. The fully sealed oil-immersed structure isolates internal components from external air and moisture, avoiding core and winding oxidation, oil deterioration and insulation aging caused by environmental factors. The product has strong lightning resistance and overload capacity, and can stably cope with peak power consumption and instantaneous voltage fluctuation.

3.3 Long Service Life and Low Aging Rate

The amorphous alloy material has stable temperature resistance and magnetic stability, with low operating temperature during full-load operation, which slows down the aging speed of insulating materials. The optimized winding structure and high-quality sealing gaskets ensure the tightness of the equipment. Under standard operating and maintenance conditions, the overall service life of the transformer can reach more than 30 years, far exceeding the service life of conventional transformers.

3.4 Environmental Protection and High Safety

The product has low operating noise, no electromagnetic pollution, and adopts environmentally friendly insulating oil and flame-retardant materials, which meets green power construction standards. The compact structural design reduces the overall floor area, and the fully enclosed structure effectively prevents oil leakage risks, avoiding environmental pollution and equipment failure caused by oil seepage. It also has good mechanical strength and can resist slight vibration and external impact in the operating environment.

It can be used for power supply of smart city supporting facilities, port and wharf engineering, highway and railway supporting power distribution projects, and can operate stably in outdoor open-air, humid and multi-dust complex environments.

5. Product Maintenance and After-sales Service

5.1 Daily Maintenance Guidelines

This series of fully sealed amorphous alloy transformers has low daily maintenance requirements, and regular inspection and maintenance can effectively extend the service life and ensure operational safety. First, conduct a visual inspection every 3 months to check for oil seepage, shell deformation, gasket aging and other abnormal phenomena, and clean the dust and dirt on the equipment surface and heat dissipation pieces. Second, perform oil quality sampling and testing every 12-18 months to detect the dielectric strength and moisture content of the insulating oil, and replace the insulating oil in time if it deteriorates.

In addition, regularly check the wiring terminals and grounding devices to ensure firm connection and good grounding performance, and avoid loose contact causing overheating failure. For equipment operating in high-load and high-temperature environments, increase the frequency of inspection, focus on monitoring operating temperature and noise, and stop operation for inspection in case of abnormal vibration or noise. It is strictly prohibited to run the transformer in overload for a long time to avoid accelerated aging of insulation components.

5.2 Fault Handling Instructions

In case of common faults such as excessive temperature, abnormal noise and tripping during operation, the equipment shall be cut off immediately for inspection, and it is forbidden to operate with faults. For minor faults such as loose wiring and surface dust accumulation, they can be eliminated on site by professional electricians; for core failure, winding damage and oil quality severe deterioration, please contact the manufacturer's after-sales team for professional maintenance, and do not disassemble the equipment privately to avoid safety accidents and equipment damage.
