Transformer core cutting line supplier today: 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.
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.

The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Because the load loss and impedance voltage increase greatly during overload, it is in non-economic operation state, so it should not be in continuous overload operation for a long time.Welcome to inquiry price for dry type substation transformer.

Laser welding machine is an efficient and precise welding method using high energy density laser beam as a heat source. Laser welding is one of the important applications of laser material processing technology. It mainly used for welding thin wall material and low speed in the 1970 s. The welding process is thermal conduction, i.e. the laser radiation heating surface, the surface heat to the internal diffusion through heat conduction, by controlling the width of laser pulse, energy, peak power and repeating frequency, parameters such as melting of components, to form specific molten pool. Because of its unique advantages, it has been successfully used in precision welding of micro and small parts.As one of the best laser welding machine manufacturers in China, Canwin specialized in handheld laser welding machine and wholesale fiber laser welding machine making for over 20 years.
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.
Connection group label: According to the phase relationship between the primary and secondary windings of the transformer, the transformer windings are connected into various combinations, which are called the connection group of the windings. In order to distinguish different connection groups, the clock notation is often used, that is, the phasor of the line voltage on the high-voltage side is used as the long hand of the clock, fixed at 12, and the phasor of the line voltage on the low-voltage side is used as the short hand of the clock. The number of the short hand indicates the connection group label. For example, Dyn11 indicates that the primary winding is (triangle) connected, and the secondary winding is (star) connected with a center point, and the group number is (11) points.
