Power transformer core fault and troubleshooting?
2022-03-14
Power transformer core Simple structure, high reliability. It is small, light, and low cost. Therefore, it is deeply loved by everyone. When you use it, you need to know the troubleshooting of the power transformer core. Because many people are not familiar with this, I will take this opportunity to explain it. If you are interested, feel free to listen.
As we all know, the power transformer works under AC conditions, and its power loss will cause the resistance of the coil to generate in the core under the alternating current magnetization. At this time, we usually call the power loss in the core iron loss, and when you use it, you must know that the two main reasons for its iron loss are hysteresis loss and eddy current loss. When using the power transformer core, you also need to know its core faults and troubleshooting? Because the windings and core of the transformer are the main components for transmitting and transforming electromagnetic energy. In this way, their reliable operation can also be well guaranteed. Of course, this is also a concern for users. Moreover, statistics show that faults caused by power transformer core problems account for three of the total transformer accidents. At this time, the manufacturing department has paid attention to the defects of the power transformer core, and should pay attention to it under grounding and monitoring. In addition, technical improvements have been made in terms of grounding.
Therefore, when encountering power transformer core failures, you know that the operation department also attaches great importance to the detection and discovery of core failures. However, power transformer core failures still occur frequently, mainly due to multiple grounding and poor core grounding. This article introduces the judgment and handling methods of the two fault conditions. The reason for grounding when installing the power transformer core is that during normal operation, there is an electric field between the energized windings and the oil tank, and the power transformer core and other metal components are in this electric field. This is mainly due to uneven capacitance distribution and different field strengths. If the power transformer core is not grounded, it will generate charging and discharging phenomena, which will seriously damage the insulation strength of solid insulation and oil, so the core must be grounded. It should also be taken seriously in the future.
The above is what I have told you Power transformer core Troubleshooting. Okay, that's all for today's knowledge points. Next time, we will bring more exciting content and knowledge points related to this product.
