The transformer is one of the important equipment in the power system, and its normal operation is of great significance to ensure the stability and safety of the power system. However, transformers can fail or be damaged for a variety of reasons, which is why they need to be serviced and replaced. Therefore, how to tell if the transformer is broken has become a skill that power workers must master.
In the process of judging whether the transformer is broken, it is first necessary to understand the normal state and abnormal state of the transformer. A normal transformer should have an even hum sound, while an abnormal transformer may have other abnormal sounds such as "squeak", "crackle", etc. In addition, a normal transformer should have no oil leakage, while an abnormal transformer may have oil leakage or oil leakage.
In addition to auditory and visual inspections, there are also tests that can be used to further tell if the transformer is broken. For example, a transformer winding insulation resistance tester can be used to test the insulation resistance between the windings, and if the insulation resistance is low or zero, the transformer may be faulty. In addition, transformer oil testing can also be used to detect various indicators of transformer oil, such as acid value, moisture, flash point, etc., if these indicators exceed the standard or do not meet the standard, it means that the transformer may be faulty.
In practice, it is necessary to select the appropriate inspection and test method for the specific situation. For some obvious faults, such as oil leaks, abnormal sounds, etc., they can be found by simple observation and auditory examination. For some hidden faults, such as inter-turn short circuit, loose core, etc., they need to be determined by professional testing and maintenance.
In the process of judging whether the transformer is broken, the following points need to be noted:
1.Proper use of test instruments and tools, compliance with safety regulations and operating procedures;
2.For hidden faults, in-depth testing and inspection are required, and no detail is easily missed;
3.In the process of testing and inspection, it is necessary to pay attention to recording data and observing phenomena for easy analysis and judgment;
4.For some faults that are difficult to determine, you can consult professional and technical personnel or seek technical support from the manufacturer.
In short, judging whether the transformer is broken requires a variety of factors and methods, and only through comprehensive and meticulous inspection and testing can the state of the transformer be accurately judged. In practical application, it is necessary to continuously accumulate experience and technical level, improve the accuracy of judgment, and ensure the stability and safety of the power system.
