Premium dry type electrical transformers manufacturer: When is it not allowed to adjust the tap changer of the transformer on-load voltage regulating device? The on-load voltage regulating device is a common accessory equipment of the transformer, which is used to adjust the transformation ratio when the transformer is running, so as to achieve the purpose of adjusting the output voltage. When using the on-load pressure regulator, the following points need to be paid attention to: It is not allowed to operate under live conditions: because the transformer is working under live conditions, the tap changer of the on-load voltage regulating device will have an arc when it is adjusted, so it is not allowed to operate the tap changer under live conditions. Frequent adjustments are not allowed: frequent adjustments to the tap changer of the on-load tap changer may cause damage to the tap changer or poor contact, thereby affecting the normal operation of the transformer.

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.
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.

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.
The transformer coils are referred to as the primary and secondary windings. When applying AC current to the primary winding of the transformer, the transformer coil creates a pulsing magnetic field. The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy.The machine is a very powerful and versatile machine which can wind a wide range of HV coils for distribution transformers using round and rectangular wires. It is fully automatic with paper strip winding.Winding material lnsulated with an epoxy resin -environmentally friendly.
The loss in magnetic flux in the transformer must therefore be minimized by providing a suitable mean between the primary and secondary windings. For this purpose, silicon steel magnetic cores are usually used. By using a core type transformer, magnetic losses are reduced and a greater amount of magnetic flux is conveyed between the primary and secondary coils, thereby increasing the transformer’s overall efficiency. Electrical materials play an important role in the field of engineering technology. Various technologies should be realized through certain equipment, and the equipment needs to be made of specific materials. Without corresponding materials, even technologies and products that are feasible in principle cannot be realized. The emergence of new materials can often bring significant technological progress.

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.
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.
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.
