Abstract ▼ AI-Helper

Nano composite materials were multi-constituent combinations of nano dimensional phases with distinct differences in structure, chemistry and properties. Nano particles were less likely to create large stress concentrations and thereby can avoid the compromise of the material ductility while improve other mechanical properties. Corona discharge was an electrical discharge. The ionization of a fluid surrounding a conductor was electrically energized. This discharge would occur when the strength of the electric field around the conductor was high enough to form a conductive region, but not high enough to cause electrical breakdown or arcing to nearby objects. This paper shows all the studies done on the preparation of nano fillers. Special attention has given to the ACSR transmission line conductor, TiO2 nano fillers and also to the evaluation of corona resistance on dielectric materials discussed in detail. The measurement of the dielectric properties of the nano fillers and the parameters influencing them were also discussed in the paper. Corona discharge test reveals that in 0%N ACSR sample corona loss was directly proportional to the applied line voltage. No significant change in corona loss between 0%N and 1%N. When TiO2 nano filler concentration was increased up to 10%N fine decrement in corona loss was found when compared to base ACSR conductor, corona loss was decreased by 40.67% in 10%N ACSR sample. It was also found from the surface conditions test that inorganic TiO2 nano filler increases the key parameters like tensile strength and erosion depth.

문제 정의

This test was aimed to calculate the surface degradation depth on the surface of both unfilled and nano coated ACSR conductor samples. The voltage applied was 72 kV to each sample for 50 hours.

제안 방법

One third was left free for the centrifugal action to be effective. After the ball milling process is over, a small amount of the sample was taken and Scanning electron microscopy analysis was done in order to determine the size of the resultant powder.
The corona discharge test was conducted by measuring the corona inception and corona extinction voltage. For both unfilled and nano filled ACSR conductor samples this corona discharge test conducted. The ACSR conductor was coated with different TiO₂ concentrations.
In this investigation the top down method approach using mechanical grinding was adopted. Mechanical attrition was a typical example of 'top down' method of synthesis of nano materials, where the material is prepared not by cluster assembly but by the structural decomposition of coarser-grained structures as the result of severe plastic deformation.
18 mm. The corona discharge test was conducted by measuring the corona inception and corona extinction voltage. For both unfilled and nano filled ACSR conductor samples this corona discharge test conducted.
The ultimate aim of this project was to measure the erosion depth on the surface of ACSR transmission line conductor and to decrease the surface flash over and also to reduce the corona loss. This work presented in this thesis represents the preliminary study that demonstrates the feasibility of the approach.
To ascertain the concept that TiO₂ nano filler increases the erosive resistivity, the surface erosion test was conducted. This test was aimed to calculate the surface degradation depth on the surface of both unfilled and nano coated ACSR conductor samples.
