Title: Improvements in protective devices for electric circuits
IPC: H02H3/00
Filed: 1928-04-04
Abstract: 288,631. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). April 14, 1927, [Convention date]. Cut-out arrangements.-A single relay serves to control the tripping of a circuit-breaker 7 in the event of a reversal of current and to control the reclosure of the breaker so that the reclosure occurs only when the voltage on the power side exceeds that on the network side. As shown, an induction-type relay has two current windings 5 supplied by the current transformer 8 in the network side and co-operating with two voltage windings 4 connected across the power side of the breaker 7. These two wattmeter elements act additively to maintain a contact-member (not shown) elosed when the power is in the normal direction and act to cause the opening of the circuit-breaker when the power reverses. In order to ensure that the breaker 7 after being switched out can only be switched in again when there is the necessary voltage on the power side, two additional windings 6 are provided one connected to the power side and the other to the network side of the switch. These windings produce opposing torques which are normally equal, and if after the breaker has been opened the voltage on the power side predominates the relay closes its contacts again and the circuit-breaker is reclosed.
