The Design of 10kV Power Distribution

Abstract In recent years, due to the rapid development of the economy and life quality ,the demand for electricity is increasing rapidly as well, and the power system and electrical equipment also need to be upgraded subsequently。 In order to ensure the safety and reliability of the power supply, the demanding for the power system and substations have become increasingly strict。 In terms of the power supply for residents and factories, the 10kV distribution is becoming more and more important。 However, the 10kV distribution is directly facing the user, therefore the design of it requires a combination of users specific circumstances, and the proper design can greatly improve the quality of people's life and production。

The design of the 10kV distribution is mainly based on the requirements of the mission statement to analyze the tendency and current situation of the users load status, then clarify the meanings and functions of the construction of the distribution, and the safety, reliability, economy are also under consideration。 Through load calculations to decide the type of transformers, capacity, and number, and to design the main connection of the distribution, then to analyze the short-circuit current to select a device。 To do the secondary circuit setting and the adjustment of relay protection on the basis of the primary circuit。 Finally, installing the lightning protection equipment to finish the design。 

Key words: power distribution system  load calculation  main connection  short-circuit current   equipment selection
