Abstract. insulator is an important part of transmission line, and its maintenance of is of great significance. Duo to The insufficiency of traditional way of insulator detection, this paper puts forward a kind of automatic on-line detection method. The sliding carriage which carries a detection device slides along the guide rail smoothly and precisely, the field data is measured reliably. Field practice shows that this technology can increase efficiency and reduce the labor intensity greatly.

Leakage currents flowing on the insulator surface depend on type and amount of the pollution accumulated on the surface. In this study, insulator leakage currents are simulated with the help of Ant Colony Algorithm (KKA). The pollution layer accumulated on the insulator surface is accepted as pheromones substances of the ants. In regard with this approach, the movement of ants, which are determined based on voltage of each point on the insulator surface, depends on amount of pollution and distance between these points. In the ant colony algorithm, pheromone substance is laid down to the trail of ants randomly and the amount of pheromone is constantly updated by multiplying with a coefficient of evaporation in order to take the evaporation into account. Similarly, the pollution layer on the insulator surface is distributed irregularly and evaporation coefficient is used to refer to a reduction in the amount of pollution caused by formation of dried bands. These bands are caused by the effect of heat produced by the flow of leakage current. The surface conductivity is calculated from the value of pheromone and the leakage current is calculated from conductivity and voltage difference between points by employing a computer software developed in accordance with this algorithm.

High-voltage suspension insulator Cement shell Electric field intensity Partial dischargeThe design features of high-voltage glass disk suspension insulators are considered in the paper. The electric field of the insulator was studied using its appropriate modeling in the Comsol Multiphysics simulation software. It was found the dependence of the maximal values of voltage applied to the insulator, under which the breakdown of the inclusion (pores) in the cement shell occurs, on the diameter of the pore. An improvement of the design of the insulator is proposed, the implementation of which consists of increasing the radius of curvature of the conical part of the rod. It is shown that with a change of the radius of curvature of the conical part of the insulator core from 0.5 to 3.5 mm, the maximal electric field intensity reduces and the threshold value of the partial discharge voltage in the cement shell increases, which will decrease the level of radio interference of the insulators. The results can be used to create new designs for high-voltage disc suspension insulators with improved radio interference performance.
