Cut to length production line manufacturer from China: Harmonics, a crucial aspect of power quality, have a significant long-term impact on distribution transformers. Harmonics refer to the distortion of the normal electric current waveform, usually due to the operation of non-linear loads like computers, LED lights, and variable speed drives. These distortions can cause increased heating in the transformer, leading to accelerated aging and reduced equipment lifespan. Furthermore, harmonics can also increase power demand and system losses. They can overload the transformer and other components of the electrical system, leading to premature failures and necessitating costly repairs or replacements. Thus, managing harmonics is an essential part of maintaining high power quality and ensuring the efficient operation of power distribution transformers.

Why does the current source inverter need a larger transformer capacity? Current source inverter is a common type of inverter. Its control method adopts current loop control, which has the advantages of high precision and strong adaptability, and is widely used in industrial production. Due to the working characteristics of the current source inverter, a large transformer capacity is required for the following reasons: The current source inverter adopts the intermediate inductance: the current source inverter adopts the intermediate inductor, which can realize the phase difference between the output voltage and the current, so as to realize the frequency conversion control. However, since the intermediate inductor needs to withstand large current and voltage, it is necessary to select a transformer with a larger capacity to ensure the normal operation of the inductor.
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.

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.

The main pillar of the smart grid is the smart substation, which is not only an important hub for power transmission and distribution, but also directly affects the operational and monitoring capabilities of the smart grid through its operational safety and stability. Through the network, information can be exchanged, and the transformer can share information with the process layer and the station control layer. On the premise of ensuring product performance, the integration of monitoring, control, measurement, protection, and metering is designed to achieve the integration of transformer components with actuators, sensors, and transformers.
Insulation level: There are standards for insulation levels. The insulation level of a transformer with a rated high voltage of 35 kV and a rated low voltage of 10 kV is represented as LI200AC85/LI75AC35, where LI200 indicates that the transformer has a high-voltage lightning impulse withstand voltage of 200 kV, a power frequency withstand voltage of 85 kV, and a low-voltage lightning impulse withstand voltage of 75 kV, and a power frequency withstand voltage of 35 kV. The current insulation level of Aux High-Tech Co., Ltd.’s oil-immersed transformer products is LI75AC35, indicating that the transformer has a high-voltage lightning impulse withstand voltage of 75 kV and a power frequency withstand voltage of 35 kV. Because the low voltage is 400 V, it can be ignored.
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.
