Hydrogen Energy Dedicated Dry-type Rectifier Transformer
The hydrogen energy dedicated dry-type rectifier transformer produced by Shanghai Zhiyou Company can effectively improve the efficiency of water electrolysis, reduce comprehensive power consumption, and enhance operational reliability. All performance indicators meet or exceed the latest national standards. The product has been successfully applied in Xinjiang off grid photovoltaic green hydrogen comprehensive application project, Xinyi hydrogen production project, etc.
Product features:
The transformer is made of non-toxic flame-retardant epoxy resin infusion, with high mechanical strength, flame retardancy, fire resistance, and no pollution.
The whole machine enters the site and can be put into operation once it is in place, which is convenient and efficient.
The insulation heat resistance level of the transformer is H level, with a heat resistance temperature of 180 ℃ and a maximum overload capacity of 200%.
Dry type rectifier transformers can be installed together with rectifiers and other electrical equipment, without the need for a separate distribution room, saving space and reducing investment.
From the initial two-dimensional electric field simulation, three-dimensional electric field measurement, and impulse characteristic measurement, to the later theoretical analysis and simulation tests on the characteristics of the transformer's main insulation, longitudinal insulation, end insulation, lead insulation, and coil under lightning impulse voltage, after years and multiple methods of verification, the reliability of transformer insulation has been ensured.
We specialize in the calculation and measurement of transformer leakage magnetic field, the shielding structure of leakage magnetic field, the calculation of transformer dynamic and thermal stability, and the improvement of transformer dynamic and thermal stability capabilities, in order to ensure the calculation of leakage inductance field and reduce stray losses, and improve transformer dynamic stability.
Shanghai Zhiyou Company has collaborated with universities such as Tsinghua University, Southeast University, Beijing University of Science and Technology, and Huazhong University of Science and Technology to jointly develop a calculation program for the temperature field of a circular wire. By calculating the loss distribution of the coil (including resistance loss, eddy current loss in different directions, and circulating current loss between parallel wires) and the cooling condition of the flow velocity field, the temperature distribution of the coil and the temperature rise of the hot spot can be accurately calculated, in order to take measures to effectively control the temperature rise of the hot spot that affects the life of the transformer.
The electric field strength of each part has been analyzed and strictly controlled during the design phase. The compliance of manufacturing quality, reliability of processing methods, and rationality of operation technology also effectively control the local discharge of transformer alarms.
Our technological advantages:
Integrating electromagnetic optimization design, parametric drawing, performance analysis and structural optimization, automatic drawing, and other functions of transformers to achieve resource sharing in transformer design, as well as searching, modifying, and version control of various data information.
The current field, temperature field, electric field, leakage magnetic field, wave process, and short-circuit force of transformers. The research and design of each series of products are carried out through simulation analysis of flow and temperature fields to determine the average temperature rise of the coil and the hot spot temperature seat, ensuring product performance.
By collecting key data such as temperature, current, voltage, vibration, and grid harmonics of transformers, online power quality analysis, fault alarms, and installation on mobile phones can be achieved.
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+parametric" 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.
The transformer body adopts a high-temperature resistant mixed insulation system, which effectively solves the problem of temperature field differences in the structure of different types of oil immersed hydrogen production rectifier transformers, ensuring the safety and reliability of the insulation system.
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
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.
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.
