Top rated dry type electrical transformers supplier: 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 core is a static device that provides a channel for magnetic flux to flow in a transformer. The core is constructed using thin strips of silicone steel. The silicon steel sheets are electrically isolated and coupled to reduce no-load losses in the transformer.The core of a transformer is made of soft iron. Transformers are used in various fields like power generation grid, distribution sector, transmission, and electric energy consumption.
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.

The cut to length line is a special equipment for the production of transformer core, is our latest generation of cross shear line. This cut to length production line is used for shearing, O punching and V notch of transformer core sheet. The special point of this ctl line is that two O punch and one V notch can work at the same time to produce transformer core pieces with 3, 5, 7 steps in vertical direction and 3, 5, 7 steps in horizontal direction.
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 extra info on https://www.canwindg.com/
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.
What is the protection scope of gas protection? In oil-immersed transformers, the scope of gas protection inside the transformer mainly includes the gas content in the transformer oil. Normally, the oil in an oil-immersed transformer is used for insulation and cooling, but when the transformer fails or ages inside, gases such as gas and hydrogen will be generated, which will lead to an increase in the gas content in the oil. If the gas content in the oil is too high, it will cause the insulation performance of the oil to decrease, which will cause the transformer to malfunction or even explode. Therefore, in order to protect the safe operation of the transformer, it is necessary to monitor and control the gas content in the transformer oil. Generally speaking, the gas relay is a commonly used gas monitoring device in oil. The gas relay can monitor the change of the gas content in the oil, and send out an alarm signal when the gas concentration exceeds a certain threshold, so as to carry out repair and maintenance in time. In short, the gas protection range inside the transformer mainly refers to the gas content in the transformer oil, which needs to be monitored and controlled by devices such as gas relays to protect the safe operation of the transformer.
