Top rated dry type electrical transformers producing company

Cut to length production line manufacturer 2024: In terms of productivity, poor PQ can cause unscheduled downtime due to equipment malfunctions or system failures. This unpredictability can significantly disrupt operations, leading to lower productivity levels and potential revenue losses. Moreover, poor PQ can lead to diminished energy efficiency. Transformers operating under poor power quality conditions often require more power to function, leading to increased energy consumption and higher operating costs. The excess power demand could also strain the electrical grid, leading to further inefficiencies and disruptions. Additionally, the costs associated with repairing or replacing damaged equipment due to poor power quality can be substantial. There are also indirect costs to consider, such as those associated with investigation and troubleshooting of power quality issues. Find more details on dry type transformer suppliers.

Oil immersed transformers are the most commonly used equipment mainly because of their simple structure and reliable operation. It has faster heat dissipation, uniform conduction, and better insulation performance than the dry-type transformer.Oil transformers are used in power distribution or electrical substations. Their transformer core and coils are immersed in oil, which cools and insulates. Oil circulates through ducts in the coil and around the coil and core assembly, moved by convection.

Power distribution cabinet transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It lowers the network voltage of 10(6)kV or 35kV to 230/400V bus voltage used by users. This kind of product is suitable for AC 50(60)Hz, three-phase maximum rated capacity 2500kVA(single-phase maximum rated capacity 833kVA, generally not recommended to use single-phase transformer), can be used in the indoor (outdoor), the capacity of 315kVA and below can be installed on the rod, the ambient temperature is not higher than 40℃, not less than -25℃, The maximum daily average temperature is 30℃, the maximum annual average temperature is 20℃, the relative humidity is not more than 90%(the ambient temperature is 25℃), and the altitude is not more than 1000m.

What is eddy current? What are the disadvantages of eddy current generation? Eddy current refers to a kind of current generated in the conductor, which is the induced current caused by the change of the magnetic field. The eddy current forms a circular current flow path in the conductor, and this current forms a motion state similar to an eddy current inside the conductor, so it is called an eddy current. The generation of eddy currents has the following disadvantages: Energy loss: Eddy currents create circular currents in conductors, which generate heat as they flow continuously in conductors. Since the generation of eddy currents is caused by changes in the magnetic field, in equipment such as transformers and motors.

Digital measurement – Digital measurement of transformers or other components can be conducted, and the measurement results can be called and collected from the process layer and station control layer through digital networks, thus monitoring transformers and other equipment.Status visualization – The operation status of transformers can be visualized and observed in the power grid.Smart grid or other related systems can express the status information of transformer self-detection or information interaction.

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.

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.
