Designing and maintaining of circuits of distribution networks with voltage of 10-0.38 kV

Abstract

The procedure for maintaining circuits in distribution networks with a voltage of 10-0.38 kV is determined in accordance with the Rules of Technical Operation, State Standard. In accordance with these documents, the types of circuits that should be in the subdivisions of electrical networks are determined. All changes in all circuits should be made immediately (after completion of installation work before commissioning), signed by the responsible person. Information on changes in the circuits should be brought to the attention of all employees for whom knowledge of these circuits is required. The need to have the same circuits in production services and subdivisions of electric networks justifies the use of modern information systems such as geographic information systems, which allow working with all types of electric network circuits in multi-user mode. In this case, users will have the most accurate information. The article describes the requirements for supporting circuits designing. The issue of input, preparation and maintenance of data is up to 90% of the cost of a serious project of a geographic information system (according to press). And only 10% is the cost of equipment and software for the geographic information system. A task requiring such costs can be effectively solved only by professional means on professional equipment. The article discusses how to enter electrical network diagrams into geographic information systems and proposes a technique for introducing overhead lines support circuits of 6-10 kV into a geographic information system.
