What should I pay attention to when conducting leakage detection operation of SF6 electrical equipment?

1. According to the standard, the SF6 electrical equipment is inflated to the rated pressure, and the gas detection can be carried out after 24 hours;

2. In order to ensure the accuracy of measurement, SF6 gas around the equipment should be blown before detection, and the residual gas between the double seal should also be drained;

3. When the local dressing method is used for leak detection, the dressing cavity should adopt regular shape as far as possible, such as square, cylinder, etc., which is easy to estimate the volume of the dressing cavity. The bandaging cavity was measured by multiple points, and the average value was taken as the test result.

4. When using the buckle method for leak detection, due to the large size of the buckle, special attention should be paid to the tightness of the buckle to prevent the leakage of the collected gas. The buckle cavity should be measured at multiple points and the average value should be the test result;

5. Qualitative leak detection is more intuitive to observe the tightness, and quantitative leak detection is used to determine the degree of leakage for the parts with doubts about qualitative leak detection
