Network protector with static and circuit

Claim 1

IN A PROTECTING APPARATUS, A CIRCUIT BREAKER HAVING POLYPHASE SUPPLY TERMINALS FOR CONNECTION TO A SOURCE OF POLYPHASE ENERGY AND POLYPHASE LOAD TERMINALS FOR CONNECTION TO A POLYPHASE LOAD, SAID BREAKER INCLUDING OPERATING MEANS FOR CONNECTING SAID LOAD TERMINALS WITH SAID SUPPLY TERMINALS, AND ACTUATING NETWORK CONNECTED TO SAID OPERATING MEANS AND EFFECTIVE IN A FIRST OPERATING CONDITION TO CAUSE SAID OPERATING MENS TO CONNECT SAID LOAD TERMINALS TO SAID SUPPLY TERMINALS, SAID ACTUATING NETWORKS INCLUDING FIRST AND SECONND STATIC SWITCHING DEVICES, EACH SAID STATIC DEVICE HAVING A MAIN CIRCUIT AND A CONTROL CIRCUIT FOR ACTUATING ITS ASSOCIATED SAID MAIN CIRCUIT FROM A FIRST TO A SECOND OPERATING CONDITION UPON THE APPLICATION OF A FIRST SIGNAL THERETO, SAID ACTUATING NETWORK BEING PLACED IN ITS SAID FIRST CONDITION SOLELY WHEN SAID STATIC DEVICES ARE EACH IN THEIR SAID SECOND OPERATING CONDITIONS, A FIRST CONTROL NETWORK HAVING AN OUTPUT CIRCUIT CONNECTED TO SAID CONTROL CIRCUIT OF SAID FIRST STATIC DEVICE AND HAVING FIRST AND SECOND INPUT CIRCUITS, FIRST CIRCUIT MEANS ENERGIZING BY A PREDETERMINED SEQUENCE OF THE VOLTAGE AT SAID LOAD TERMINALS AND CONNECTED TO SAID FIRST INPUT CIRCUIT, SAID FIRST CIRCUIT MEANS BEING EFFECTIVE TO SUPPLY A SECOND SIGNAL IN RESPONSE TO SAID PREDETERMINED SEQUENCE VOLTAGE AT SAID LOAD TERMINALS, SECOND CIRCUIT MEANS ENERGIZED BY A VOLTAGE DIFFEENTIAL EXISTING BETWEEN THE VOLTAGE AT SAID LOAD TERMINALS AND THE VOLTAGE AT SAID SUPPLY TERMINALS AND CONNECTED TO SAID SECOND INPUT CIRCUIT, SAID SECOND CIRCUIT MEANS BEING OPERABLE TO SUPPLY A THIRD SIGNAL IN RESPONSE TO A PREDETERMINED CHARACTERISTIC OF SAID DIFFERENTIAL VOLTAGE, SAID FIRST CONTROL NETWORK BEING EFFECTIVE TO SUPPLY SAID FIRST SIGNAL TO ITS SAID OUTPUT CIRCUIT WHEN ENERGIZED WITH SAID SECOND AND SAID THIRD SIGNALS, A SECOND CONTROL NETWORK HAVING AN OUTPUT CIRCUIT CONNECTED TO SAID CONTROL CIRCUIT OF SAID SECOND STATIC DEVICE AND HAVING FIRST AND SECOND INPUT CIRCUITS, THIRD CIRCUIT MEANS ENERGIZED BY A DESIRED SEQUENCE OF THE VOLTAGE AT SAID LOAD TERMINALS AND CONNECTED TO SAID FIRST INPUT CIRCUIT OF SAID SECOND CONTROL NETWORK, SAID THIRD CIRCUIT MEANS BEING EFFECTIVE TO SUPPLY A FOURTH SIGNAL IN RESPONSE TO SAID DESIRED SEQUENCE VOLTAGE AT SAID LOAD TERMINALS, FOURTH CIRCUIT MEANS ENERGIZED BY A VOLTAGE DIFFERENTIAL EXISTING BETWEEN THE VOLTAGE AT SAID LOAD TERMINALS AND THE VOLTAGE AT SAID SUPPLY TERMINALS AND CONNECTED TO SAID SECOND INPUT CIRCUIT OF SAID SECOND CONTROL NETWORK, SAID FOURTH CIRCUIT MEANS BEING OPERABLE TO SUPPLY A FIFTH SIGNAL IN RESPONSE TO A PREDETERMINED CHARACTERISTIC OF SAID DIFFERENTIAL VOLTAGE, SAID SECOND CONTROL NETWORK BEING EFFECTIVE TO SUPPLY SAID FIRST SIGNAL TO ITS SAID OUTPUT CIRCUIT WHEN ENERGIZED WITH SAID FOURTH AND SAID FIFTH SIGNALS.
