发明名称 Method of monitoring electrical wear on selector switch disconnectors in a high voltage station
摘要 The present invention relates to a method of monitoring electrical wear on selector switch disconnectors in a bay of a high voltage station that includes a set of distribution busbars connected to at least three electrical circuits constituted by an inlet bay, an outlet bay, and a bay for coupling together the busbars. During an operation of transferring a bay under load, when the computer of the corresponding bay detects that the disconnectors of its lines for connection to the distribution busbars are closed, the computer sends a message to the other computers which then determine and store data comprising the magnitude and the polarity of the current flowing through the corresponding bays, and when the computer of the bay in which transfer is taking place has detected opening of the selector switch disconnector in the line for connection to the busbar from which distribution has been transferred, said data prior to the opening is stored and the square of the current interrupted by said disconnector is calculated.
