In the power system, it is often necessary to conduct insulation strength tests on electrical products, equipment, insulation materials, etc. at specified voltages to assess the insulation level of products. At this time, we will use test transformers, DC high-voltage generators, series resonance, etc. to complete this test. Today, we will mainly analyze a type of test transformer: oil immersed test transformer, What aspects do we need to consider when choosing an oil immersed test transformer?
1. Voltage level: In China, oil immersed test transformers generally have voltage levels of 5, 10, 25, 35, 50, 100, 150, 300kV, etc. These voltage levels can be used for power and electronic equipment testing and research. The higher the voltage level, the larger the capacity and voltage output of the transformer.
2. Capacity level: Transformers have capacities of 3, 5, 10, 25, 50, 100, 150, 200kVA, etc. Different capacities correspond to different voltage and current output capabilities. Generally speaking, the larger the capacity level of a transformer, the greater the current and voltage it can output.
3. Voltage adjustment: The voltage adjustment of a transformer can be achieved by changing the number of turns of the secondary coil. When the secondary load increases, the primary current increases and the magnetic flux also increases to maintain the total magnetic flux unchanged.
4. Volume and weight: The oil immersed test transformer has a larger volume and heavier weight. If the transformer needs to be moved frequently, the portability and transportation cost of the equipment need to be considered.
5. Noise level: When using transformers, it is important to consider the noise level, as excessive noise can have a negative impact on the environment.
6. Insulation: The insulation of a transformer is an important factor to consider when selecting a transformer. Oil immersed test transformers have a high insulation level and anti-interference ability.
7. Applicable occasions: Oil immersed test transformers are suitable for testing and research of power and electronic equipment in various occasions.
