High quality dry type transformers producing company: 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 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.
Epoxy resin is non – combustible, flame retardant, self – extinguishing solid insulation material, safe and clean. It is also a solid insulation material with proven insulation and heat dissipation technology for more than 40 years.Epoxy resin products can be used for dry type transformer, for insulation parts, for instrument transformer, for electrical composite parts and for room temperature curing. Epoxy resin dry transformer uses epoxy resin as insulation material.

The transformer core provides a magnetic path to channel flux. The use of highly permeable material (which describes the material’s ability to carry flux), as well as better core construction techniques, helps provide a desirable, low reluctance flux path and confine lines of flux to the core. An electrical distribution cabinet is a part of an electrical system whose task is to distribute electrical energy. It includes distribution, protection, measurement, control and signaling instruments. The electrical distribution box also contains wires, various types of insulation, and support components.

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.
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.
What are the consequences of parallel operation of transformers that do not meet the parallel operation conditions? Parallel operation of transformers that do not meet the parallel operation conditions may lead to the following consequences: Voltage instability: Different transformers may have different electrical parameters, such as transformation ratio, resistance, inductance, etc. If these transformers with different parameters are forced to run in parallel, the overall electrical parameters after paralleling may be unstable, thereby affecting the quality of power supply. Uneven load distribution: If the transformers with uneven load distribution are forced to run in parallel, different transformers may bear different loads, thus affecting the service life and stability of the transformers. Excessive temperature rise: If different transformers are operated in parallel, their heat dissipation conditions and methods may be different, which may cause excessive temperature rise of some transformers, and may even damage the transformer.
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.
