Abstract:
1. Method to prevent the formation of electrical arcs in a connector inserted into a line of supply of a power load, said connector ( 11 ) being of the type that is made up of first and second electroinsulator supports (l, 2 ) carriers of at least one pair of terminals ( 3 , 4 ) capable of freely coupling to a plug, said terminals ( 3 , 4 ), being in a coupling position for said electroinsulator supports ( 1 , 2 ), joined electrically between themselves establishing a channel ( 5 ) for the passing of energy towards said power load ( 10 ) and, in a coupling position forth electroinsulator supports ( 1 , 2 ), the terminals ( 3 , 4 ) separate physically interrupting said channel ( 5 ), said connector being inserted into a network of supply and distribution of electrical energy in which there are primary means of detection linked to an electronic unit ( 20 ) to continually detect a first voltage (V 1 ) of supply of said network at a first point ( 22 ) situated on said channel ( 5 ) before the connector ( 11 ), the level of the aforementioned voltage being such that the aforementioned physical separation of the pair of terminals ( 3 , 4 ) may generate an electrical arc, characterized by including the steps for: a) detecting, by means of the secondary means of detection linked to said electronic unit ( b) comparing said first and second voltages (V in the event that within a predetermined minimum time interval, a difference detected between the first and second voltages (V 1 and V 2 ) is greater than the predetermined threshold indicative of a sudden interruption in the aforementioned channel ( 5 ) for the passing of electrical energy or in said secondary means of detection; c) cutting, by means of a protection device by disconnection ( characterized by said network of supply and distribution of electrical energy including several of said loads ( 10 a , 10 b ) supplied through respective channels ( 5 a , 5 b ) for the passing of electrical energy, at least one of said connectors( 11 a , 11 b ) being inserted into each one of said channels ( 5 a , 5 b ) between the aforementioned first and second points ( 22 , 23 ), said method made up of: simultaneously carrying out the aforementioned steps a) and b) for each of the several channels ( differentiating, by means of an identification circuit ( carrying out step c) for the channel or channels (
