Abstract

Abstract. Two-wheeled vehicles, namely motorbikes, are still the mainstay as an affordable means of transportation for the majority of Indonesian people. Motorcycles are a means of transportation that are often found, both in urban and rural areas. Motorcycles have many advantages compared to other means of transportation Tires are an important part of land vehicles, tire conditions that are not in accordance with the standards can cause tire bursts which result in traffic accidents. Frictional forces that occur in the tires can cause wear on the tires. Various factors that affect wear include the speed of movement and the amount of load. In this study an analysis was carried out to find out how the effect of load and speed on the resulting frictional cross-sectional area. The analytical method used in this study is Kruskall-Wallis and Mann-Whitney. Penelitian ini menghasilkan kesimpulan bahwa faktor beban memiliki pengaruh yang signifikan terhadap penampang gesekan ban sepeda motor pada lintasan beton. Sedangkan perlakuan atau faktor kecepatan tidak memiliki pengaruh yang signifikan terhadap penampang gesekan ban sepeda motor pada lintasan beton.

Abstract

Abstract. The development of technology in the current era is very rapid and has an impact on increasing electrical energy which is a major need for large industries and households. One of the electrical energy delivery equipment in the transmission system is a PMT or High Connection Breaker. This PMT is a mechanical equipment equipped with sulfur hexafluoride (SF6) gas arc extinguishing media. The process of extinguishing the arc occurs due to contact due to work from the movement that causes the contact to cause an arc. This decrease in SF6 gas pressure greatly affects reliability when operating, because the arc extinguishing process is not perfect. This is determined by the age of the equipment and the number of operating breakers. The results showed that SF6 gas which is in accordance with the standard normal pressure of 6.4 bar with an ambient temperature of 34°C can minimize the occurrence of equipment damage because it is able to approach arc pressure with SF6 gas velocity of 58 cm/s.kA, with a contact gap of 3,61224. cm, while the PMT cannot be operated at a pressure of 5.2 bar with an ambient temperature of 34°C because the speed of SF6 gas is 82 cm/s.kA with a contact gap of 5.10696. It is concluded that the higher the pressure affects the speed and distance when extinguishing the arc. several factors that affect the decrease in SF6 gas pressure using the FMEA method based on the highest value of the Risk Priority Number (RPN) of 810. Keywords: fire arc, Breakdown, Voltage breaker, SF6 . gas pressure
