Abstract ▼ AI-Helper

HVDC technology has become popular as an economic mode of bulk power transmission over very long distances. Polymeric insulators in HVDC power transmission lines are affected by surface tracking and erosion problems due to contamination deposit, which pose a greater challenge in maintaining the reliability of the HVDC system. In addition, polymeric insulators are also naturally affected by aging due to various environmental stresses, which in turn accelerates the surface tracking and erosion problems. Research works towards the improvement of tracking and erosion resistance of polymeric insulators by adding nano-sized fillers in the base material are being carried out worldwide. However, surface tracking and erosion performance of nano-filled aged polymeric insulators for HVDC applications are not well reported. Hence, in the present work, tracking and erosion resistance of the nano $Al(OH)_3$ filled silicone rubber insulation material has been evaluated under DC voltages at different filler concentrations and aged conditions, as per IEC 60587 test procedures. Leakage current and contact angle measurements were carried out to understand the surface hydrophobicity. Moving average technique was used to analyze the trend followed by leakage current. Water aged specimen shows less tracking resistance when compared with thermal aged specimen. It is observed that nano-filler concentration of 5% is even sufficient to get better tracking/erosion resistance under DC voltages.

제안 방법

The effect of aging & nano filler concentration of specimens on the tracking was analyzed through the LC measurement.
Al(OH)₃ of size <50 nm, purity >99% supplied by Hefei Jiankun Chemical Industry was used for making nano-size filled silicone rubber specimens. The samples were prepared at different filler concentrations such as 5, 10, 20 and 30% by weight of the nano-fillers. The silicone polymer and fillers were weighed accurately and mixed thoroughly.
In order to understand the eroded volume of the material due to tracking test, the weight of the sample before and after tracking test were measured. Table 2 shows the comparison of the weight loss of the nano Al(OH)₃ filled silicone rubber material due to tracking test at different filler concentrations and different aging conditions.
Also, considerable reduction in tracking length is observed when the filler concentration level increases above 10%. From the above reported results, it is observed that tracking time, eroded mass and tracking length of the silicone rubber material are closely related to each other and all these parameters gives significant information about the tracking and erosion resistance of the nano filled silicone rubber material.

이론/모형

1 shows the schematic diagram of the experimental setup and the electrode configuration used in the study. The tracking resistance test on the nano filled silicone rubber material was carried out following the IEC-60587 inclined plane test method. The gap distance between the high voltage and the ground electrode was adjusted to be equal to 50 mm.
