Dry type transformer manufacturer factory from China: 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.

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.
Heating of Cables, Motors, and Transformers: Poor power quality can lead to excessive heating in cables, motors, and transformer core cutting machine. This can accelerate the ageing of these components, shorten their lifespan, and potentially lead to catastrophic failures. Maintaining high power quality, including minimizing voltage unbalances, is critical for ensuring the efficient operation of electrical equipment and avoiding the potential negative consequences associated with poor power quality. In conclusion, maintaining high power quality is of paramount importance for the optimal performance and longevity of transformer equipment. High-quality power ensures efficient energy consumption, reduces operational costs, and extends the lifespan of the equipment. It also minimizes the risk of malfunctions, data corruption, and excessive heating of cables, motors, and transformers – issues often associated with poor power quality.

As a result of mutual inductance, a transformer produces a transformed voltage or current when the magnetic flux produced by one winding (primary winding) links with another winding (secondary winding). There is a magnetic coupling between these two windings, and they are electrically isolated. In addition, magnetic reluctance is also known as opposition to magnetic flux flow. If, for example, the magnetic flux produced by a primary winding passes through air or any nonferrous material in order to reach a secondary winding in a transformer, it would result in a reduction in magnetic flux. Due to the high reluctance of air or nonferrous materials, it will reduce magnetic flux. Find more info at canwindg.com

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.
