Top electrical equipment supplier: Harmonics, a crucial aspect of power quality, have a significant long-term impact on distribution transformers. Harmonics refer to the distortion of the normal electric current waveform, usually due to the operation of non-linear loads like computers, LED lights, and variable speed drives. These distortions can cause increased heating in the transformer, leading to accelerated aging and reduced equipment lifespan. Furthermore, harmonics can also increase power demand and system losses. They can overload the transformer and other components of the electrical system, leading to premature failures and necessitating costly repairs or replacements. Thus, managing harmonics is an essential part of maintaining high power quality and ensuring the efficient operation of power distribution transformers.

What does the rated value on the nameplate of the transformer mean? The rated value on the transformer nameplate refers to some important electrical parameters and performance indicators of the transformer. Usually includes the following aspects: Rated capacity: The rated capacity of a transformer refers to the maximum load electric power that the transformer can continuously supply. For example, a 10MVA transformer means that the transformer’s maximum load can reach 10 megawatts. Rated voltage: The rated voltage of the transformer refers to the design voltage of the transformer. For example, a 220kV/110kV transformer means that the input voltage of the transformer is 220 kV and the output voltage is 110 kV. Rated frequency: The rated frequency of a transformer refers to the power frequency for which the transformer is designed. In China, the power frequency is usually 50Hz. Short-time withstand current: The short-time withstand current of a transformer refers to the maximum current value that the transformer can withstand in a short period of time. For example, the short-term withstand current of a transformer is 50kA, which means that the transformer can withstand an instantaneous current of up to 50 kA.
What is the capacity of the transformer related to? The capacity of the transformer refers to the maximum load electric power that the transformer can bear. The capacity of the transformer is related to the following factors: Input voltage and output voltage: The input voltage and output voltage of the transformer determine the transformation ratio of the transformer, which affects the capacity of the transformer. The higher the input voltage of the transformer and the lower the output voltage, the larger the transformation ratio and the larger the capacity. Load nature: Different loads have different power factors, harmonic content and other characteristics, which affect the capacity of the transformer. For inductive loads, the capacity of the transformer can be appropriately reduced; for nonlinear loads, the capacity of the transformer needs to be appropriately increased.

Oil immersed transformers are the most commonly used equipment mainly because of their simple structure and reliable operation. It has faster heat dissipation, uniform conduction, and better insulation performance than the dry-type transformer.Oil transformers are used in power distribution or electrical substations. Their transformer core and coils are immersed in oil, which cools and insulates. Oil circulates through ducts in the coil and around the coil and core assembly, moved by convection.
A transformer coil winding machine is an intricate piece of machinery with an essential role in the manufacturing of transformers, combining modern technology and meticulousness to create high-quality products efficiently. The process starts with the feeding of copper wire into the machine, which passes through a line-up of calibrations guides and tensioners designed to secure alignment and prevent damage. An automated system then causes rotation, gradually looping copper wire around the transformer coil. A computerized system oversees variables such as speed, pitch control, layer count and insulation thickness for consistent turns. Moreover, for distinct transformer models or designs, these machines can be fitted with extra features such as automatic lead cutting and tapping mechanisms for increased versatility and productivity.
The loss in magnetic flux in the transformer must therefore be minimized by providing a suitable mean between the primary and secondary windings. For this purpose, silicon steel magnetic cores are usually used. By using a core type transformer, magnetic losses are reduced and a greater amount of magnetic flux is conveyed between the primary and secondary coils, thereby increasing the transformer’s overall efficiency. Electrical materials play an important role in the field of engineering technology. Various technologies should be realized through certain equipment, and the equipment needs to be made of specific materials. Without corresponding materials, even technologies and products that are feasible in principle cannot be realized. The emergence of new materials can often bring significant technological progress.

As a professional energy storage system manufacturer, Canwin specialized in battery energy storage system and containerized energy storage system manufacturing. An energy storage system, often abbreviated as ESS, is a device or group of devices assembled together, capable of storing energy in order to supply electrical energy at a later time. In the energy storage systems, the lithium energy storage battery only interacts with the energy storage converter at high voltage, and the converter takes power from the AC grid to charge the battery pack. Or the battery pack supplies power to the converter, and the electric energy is converted into AC by the converter and sent to the AC power grid.
Impedance voltage (%): Short-circuit the secondary winding of the transformer and slowly increase the voltage on the primary winding. When the short-circuit current of the secondary winding equals the rated value, the voltage applied on the primary side is the impedance voltage. It is usually expressed as a percentage of the rated voltage. Phase number and frequency: Three-phase is represented by S, and single-phase is represented by D. The frequency f of China’s national standard is 50Hz.There are countries abroad with 60Hz (such as the United States).I. Temperature rise and cooling: The difference between the temperature of the transformer winding or upper oil layer and the temperature of the surrounding environment is called the temperature rise of the winding or upper oil layer. The limit value of the temperature rise of the oil-immersed transformer winding is 65K, and the temperature rise of the oil surface is 55K.There are also various cooling methods: oil-immersed self-cooling, forced air cooling, water cooling, tube type, sheet type, etc.
