Cut to length production line manufacturer factory today: 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.

Current source inverter has a higher power factor: The current source inverter has a higher power factor, which can achieve higher power factor correction, thereby reducing grid harmonic pollution. However, since a higher power factor requires larger capacitor support, a transformer with a larger capacity needs to be selected to meet the power supply requirements of the capacitor. Current source inverter needs additional power supply: The circuit of current source inverter needs additional power supply to ensure the normal operation of the current loop control. These additional power sources need sufficient capacity to support, so a transformer with a larger capacity needs to be selected to meet the power supply requirements. Therefore, the current source inverter needs a larger transformer capacity to ensure the normal operation of the intermediate inductor, support the power supply of the capacitor and meet the power supply requirements. When selecting a transformer, it needs to be selected according to the actual electrical parameters and performance requirements to ensure the normal operation and stability of the inverter.

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.

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.
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 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.
