Description

Technical Field

[0001] The present invention relates to the technical field of transformers, in particular to a transformer that is convenient for heat dissipation. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] Transformers can be divided into the following categories according to their uses: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, corner transformers, high current transformers, excitation transformers, etc.

[0004] Transformers are basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. There are about 17 million transformers in operation in my country, with a total capacity of about 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution losses, and have great energy-saving potential. In order to accelerate the promotion and application of high-efficiency energy-saving transformers, improve the efficiency of energy resource utilization, and promote green, low-carbon and high-quality development.

[0005] As the country strengthens its carbon emission reduction efforts and society pays more and more attention to clean energy, the construction of clean energy power stations has become a focus of attention. As an important link in the transmission of clean energy, the construction of reliable substations can promote the development and utilization of clean energy, play an important role in the adjustment of energy structure, optimize the power network structure, improve energy utilization efficiency, and promote economic development and social progress.

[0006] In the future, with the simultaneous implementation of multiple measures such as technological innovation, expansion of installed capacity, and optimization of the entire industrial chain, the cost per kilowatt-hour of wind power is expected to continue to decline, and its cost advantage in renewable energy will be more prominent. Large-capacity single units will be more conducive to improving the utilization efficiency of wind energy resources and land resources, helping wind farm developers and operators to improve power generation efficiency, reduce maintenance costs and reduce land use. This is an inevitable trend in the future development of the wind power industry. The capacity of wind turbines will continue to increase in the future. Therefore, it is necessary to increase investment, strengthen technological research and development, and build advanced substations to make significant contributions to the country's energy security and economic prosperity. Large-capacity, environmentally friendly and energy-saving prefabricated substations should be designed and developed to fill the technological gap in this field.

[0007] Due to the strong seasonality, low annual average load rate and long no-load time of wind power and photovoltaic power generation, it is inevitable that the no-load loss of wind / photovoltaic dedicated transformers must be as low as possible. The core transformer of the large-capacity, environmentally friendly and energy-saving prefabricated substation is made of high-quality high-magnetic permeability oriented silicon steel material, and the transformer winding is made of high-purity oxygen-free copper. Through optimized design, it has lower no-load loss and load loss characteristics.

[0008] Stable insulation safety features. Wind and photovoltaic power generation fluctuates frequently and uncontrollably with wind speed or sunlight intensity, causing frequent, uncontrollable changes. Wind / photovoltaic transformers are subject to frequent low-load to high-load cycles, which in turn subject the transformers to frequent hot and cold cycles. This cycle induces repetitive thermal stresses in the windings, transformer body, and clamping components. This causes air (or nitrogen) to be absorbed by the hot oil, which releases it into tiny bubbles that adhere to the insulation, causing partial discharges or hot spots, accelerating insulation failure. The core transformer in this large-capacity, environmentally friendly, and energy-saving prefabricated substation features a fully sealed oil tank exterior. Internally, optimized insulation layout and high-quality insulation materials ensure stable insulation safety features.

[0009] Currently, existing transformers are unable to quickly dissipate heat when in use. Traditional transformers use a fixed heat dissipation design, which has the problem of poor heat dissipation effect and needs to be improved. Summary of the Invention

The docking hinge shaft 40 drives the sliding tooth plate 39 to slide on the track frame 50, and the side end of the sliding tooth plate 39 is limitedly connected to the spring rod 49, which can cooperate to perform telescopic adjustment to achieve the stable adjustment function of the sliding tooth plate 39. The sliding tooth plate 39 is meshed with the second tooth plate 47, and the second tooth plate 47 is meshed with the first tooth plate 46. At this time, The first toothed disc 46 and the second toothed disc 47 rotate in opposite directions, and the two first heat sinks 37 are driven to rotate in opposite directions through the guide rod 48, thereby expanding the contact surface with the air and better performing heat dissipation regulation. The lower end of the plate-type radiator 21 is directly connected to the second heat sink 38 through the guide plate. Since the second heat sink 38 is a fixed design, it can directly guide heat. Then the heat can be guided to the first heat sink 37 through the second heat sink 38 through the support plate 45. The angle of the first heat sink 37 can be changed, thereby changing the contact surface with the air and improving the heat dissipation effect.
