At present, the traditional dielectric strength test device for insulating oil has a viscosity of no more than 350mm at 40°C. 2 / s low-viscosity insulating oil has better adaptability, but for high-viscosity insulating oil, such as high-viscosity silicon insulating oil, polyisobutylene, etc., it needs special treatment in advance before using special specific test equipment to test the dielectric strength Tests, often with different processing methods and different specific test instruments, have large deviations and poor comparability, which affects the accuracy of real test results. At present, there is no one that can better integrate low-viscosity and high-viscosity insulating oils. General test device for strength test
