Core cutting line manufacturer from China: Why should the iron core of the transformer be grounded? Transformer core grounding is for safety and electromagnetic compatibility considerations. On the one hand, grounding the transformer core prevents contact voltages caused by ground faults, which can pose a shock hazard to humans. Because when a ground fault occurs on one side of the transformer, the iron core on the other side may have a voltage in contact with the earth. If it is not grounded, this voltage cannot be released. On the other hand, grounding the transformer core can also reduce electromagnetic radiation interference, especially for radio equipment and communication systems. This is because the current will generate a magnetic field in the iron core. If the iron core is not grounded, this magnetic field may leak into the surrounding environment and interfere with the normal operation of other equipment. In conclusion, grounding the transformer core is a protective measure against shock hazards and electromagnetic interference. See more information at dry type transformer manufacturers.
The efficiency of the transformer refers to the energy conversion efficiency of the transformer, that is, the ratio of the output power to the input power. Improving the performance of transformers can reduce energy loss and energy consumption, thereby improving the economy and reliability of transformers. Here are a few ways to improve transformer performance: Optimizing transformer design: When designing a transformer, optimized design methods can be used, such as reducing the reluctance of the iron core and winding, reducing copper loss and iron loss, etc., thereby reducing the energy loss of the transformer and improving performance. Choose high-quality materials: When manufacturing transformers, you can choose high-quality materials, such as low-loss silicon steel sheets, high-conductivity materials, etc., to reduce material loss and energy consumption and improve performance.
When these harmonic currents flow through a transformer, they can cause increased core losses due to hysteresis and eddy currents. Hysteresis loss is related to the magnetization and demagnetization of the transformer’s core material in response to the alternating current. Eddy current loss occurs when induced currents circulate within the core material, creating local magnetic fields that oppose the main field. Both these losses increase with the frequency of the current. Thus, higher frequency harmonic currents can lead to considerably higher core losses, reducing the transformer’s efficiency and causing it to overheat, which can shorten its lifespan.

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.
As a result of mutual inductance, a transformer produces a transformed voltage or current when the magnetic flux produced by one winding (primary winding) links with another winding (secondary winding). There is a magnetic coupling between these two windings, and they are electrically isolated. In addition, magnetic reluctance is also known as opposition to magnetic flux flow. If, for example, the magnetic flux produced by a primary winding passes through air or any nonferrous material in order to reach a secondary winding in a transformer, it would result in a reduction in magnetic flux. Due to the high reluctance of air or nonferrous materials, it will reduce magnetic flux. See even more information at https://www.canwindg.com/
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.
With the development of the times, people’s demand for power supply and the reliability of power supply are increasingly high, so the smart grid has emerged accordingly.In the power system, the core and hub of the substation is the transformer.The function of the transformer is mainly to distribute and convert electric energy. The normal operation of the transformer directly affects the normal function of the substation.The intelligent operation of the transformer mainly involves the protection and status monitoring of the transformer, so as to achieve real-time monitoring of the transformer and ultimately ensure the safety and reliability of power supply.
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, dock CNC machinery and equipment, etc. Simply put, dry-type transformers refer to transformers whose iron cores and windings are not impregnated with insulating oil. The relevant technical parameters of dry-type transformers include: Rated capacity (kVA): The capacity that can be delivered during continuous operation at rated voltage and rated current. Rated voltage (kV): The working voltage that a transformer can withstand during long-term operation.
