Marine Transformer

Marine power transformers (hereinafter referred to as transformers) are electrical equipment installed on ships, offshore platforms, and other places for lighting, power, communication, or grid isolation under normal operating conditions. This series of transformers is a dry-type self cooling anti drip transformer suitable for voltages below 11KV, frequencies of 50Hz and 60Hz, and capacities of 1-2000KVA. The iron core of the transformer is a core structure, made of high-quality cold-rolled silicon steel sheets stacked together, which can firmly fix the winding and minimize vibration under usage conditions; The coil is made of high-quality high insulation enameled wire or wrapped wire, with insulation levels of B, F, and H. Protection type: divided into drip proof (IP22, IP23, IP44) and waterproof transformer (IP55).

Product features:

1. Super strong insulation, three anti vibration.
2. Good heat dissipation conditions and strong overload capacity.
3. Low loss, low partial discharge, and low noise.
4. Anti salt spray, anti mold, and moisture-proof.

Performance characteristics:

1. Modular cabinet: The cabinet adopts modular disassembly and assembly, which is convenient and fast to install;
2. Noise reduction: Adopting a through screw structure, the noise reduction effect is significant;
3. Special process: The coil is coated multiple times, and the electrical and mechanical connectors are treated with special processes to enhance the "three protections" performance;
4. Cold rolled silicon steel sheet 45 °: The iron core is made of 0.18-0.3mm thick high magnetic conductivity high-quality grain oriented cold-rolled silicon steel sheet, using a 45 ° fully inclined seven step joint and square tube pull plate structure; The heart pillar is tied with insulation tape; The surface of the iron core is coated with special resin to prevent moisture and rust. Low loss and low noise.

Usage conditions:

1. The ambient temperature is -25 ℃~45 ℃, and the relative humidity is ≤ 95%;
2. Vibration and impact generated during work in transformer installation sites;
3. Swing angle ≤ 22.5 °, tilt angle ≤ 15 °;
4. There are effects of condensation, oil mist, salt mist, and mold.

Advanced production technology ensures the reliability of products:

1. 3D design: Based on more than 30 years of experience in design, manufacturing and experiment in the transformer industry, Shanghai Zhiyou Company has developed a set of pioneering "3D+parameterized" design software, which can realize automatic design and cost optimization, simulation and emulation, fully consider the requirements of national and industrial standards, and ensure the progressiveness of product design.
2. High voltage winding: The high-voltage winding conductor is made of high-quality conductor winding, reinforced with long and short cut glass fiber felt as filler, and poured by the world-class Heinrich vacuum casting system in a vacuum state. Effectively suppress the occurrence of partial discharge phenomenon, with a partial discharge capacity of less than 5pC.
3. Low voltage winding: The low voltage winding adopts high-quality pin conductors and is wound on an automatic box winding machine. The winding machine adopts the technology of "wire hydraulic energy-saving tension curling device", high-precision detection of ± 0.5mm, and advanced hydrogen arc welding technology, which plays a key role in ensuring the quality of coil winding.
4. Iron core: The iron core adopts a multi-stage step through positioning structure, and under various working conditions, the iron core has no lateral or longitudinal displacement.
5. High quality insulation:

The transformer body adopts a high-temperature resistant mixed insulation system, which effectively solves the problem of temperature field differences in different types of transformer structures and ensures the safety and reliability of the insulation system.

6. Advanced winding technology:

Made of high-quality conductor winding and reinforced with long and short cut glass fiber felt, it is poured under vacuum using the world-class Heinrich vacuum casting system

7. Fully automatic core lamination technology:

The robot is fully automatic in laminating, adopting a fully inclined 45 degree 7-step ladder joint structure, which improves the efficiency and quality of transformer laminating.

8. Testing and Inspection Techniques

All products strictly control the production process and quality links, and undergo strict testing and inspection according to national standards and customer customized requirements before leaving the factory, including partial discharge inspection, lightning impact resistance inspection, noise inspection and other necessary inspection items. Advanced testing equipment and a comprehensive inspection and testing system ensure the high quality and excellence of the products.
