These testing items are important means to ensure the quality and performance of the ultra-high voltage transformer mutual inductor vacuum oil filling platform. Through regular testing and maintenance, potential problems can be discovered and resolved in a timely manner, and the operating efficiency and safety of the platform can be improved.

Test objects:

Mutual inductor body: Check the performance of the mutual inductor after oil filling, such as insulation resistance, dielectric loss, and electric field distribution.

Vacuum oil filling system: Test the sealing performance, flow control, pressure regulation and other parameters of the oil filling system to ensure that the system can inject the appropriate amount of oil as required.

Oil quality: Conduct quality testing on the injected oil, including the physical properties of the oil (such as viscosity, flash point, etc.) and chemical properties (such as acidity and alkalinity, water content, etc.) to ensure that the oil quality meets the requirements.

Platform control system: Test the stability and accuracy of the control system, including the performance testing of components such as sensors, control valves, and actuators.

In practical applications, according to specific circumstances, other aspects may also need to be tested. In short, the purpose of the test is to ensure that the ultra-high voltage transformer mutual inductor vacuum oil filling platform can achieve the expected effect during the process of injecting the oil, and to ensure the performance and safety of the mutual inductor.
