A METHOD IMPROVING THE ELECTRICAL PERFORMANCE OF THE CONNECTIONS OF THE VARIOUS ELEMENTS IN THE ELECTRIC POWER SYSTEMS.

摘要

The method proposes a new way of connecting the various elements of the electric networks (e. g. current conductors, bars, isolators, switches, surge arresters, etc). The method is based on the principle that the connections of the elements of the power systems have to serve two different tasks: a good electric transit resistance and a resistant mechanical connection. Therefore, the respective connections have to be considered as being consisted of two parts that are materialized by separate components. The first one is the mechanical contact that should withstand the operating mechanical distresses and also protect the sensitive electric contact from any mechanical distress and the second component is the electric contact that is determined to keep a low transit resistance and also remain unaffected by the environmental factors (corrosion, etc. ). In order to achieve a good electric contact between the current conductors and other power elements, a metal welding method and preferably the exothermic welding process is used. In order to achieve a resistant mechanical contact which protects the more sensitive electric contact from any mechanical distress, a suitable arrangement of clamps is used.
