Premium slitting line supplier factory: 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.

Rising temperature: The capacity of the transformer will decrease as the temperature rises. Therefore, it is necessary to consider the appropriate heat dissipation method and heat dissipation area when designing the transformer to ensure that the temperature rise of the transformer does not exceed the allowable range. Connection method: Different transformer connection methods, such as star, delta, etc., will also affect the capacity of the transformer. For the star connection, the capacity of the transformer can be increased by about 3 times; for the delta connection, the capacity of the transformer is relatively small. Insulation level: The insulation level of the transformer determines the insulation capability and safety performance of the transformer, and also affects the capacity of the transformer. To sum up, the capacity of the transformer is related to factors such as input voltage and output voltage, load nature, temperature rise, connection method and insulation level. When selecting a transformer, it is necessary to comprehensively consider various factors according to the actual situation to ensure the normal operation and stability of the 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.
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.
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.

To accommodate the needs of grid voltage changes, the high-voltage side of the transformer has taps, which can be adjusted by adjusting the number of turns in the high-voltage winding to regulate the output voltage on the low-voltage side. Rated current (A): The current allowed to pass through the transformer for a long time under rated capacity. No-load loss (kW): The active power drawn when a rated voltage at rated frequency is applied to one winding terminal and the remaining windings are open circuit.It is related to the performance and manufacturing process of the core silicon steel sheet, as well as the applied voltage.
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.
