Abstract

PURPOSE:To disconnect an in-use and a stand-by circuit without exerting any influence upon the in-use circuit if the stand-by circuit part and a switching part become faulty by devising switches for switching between the in-use and stand- by circuit and connections of the switches. CONSTITUTION:A line 1 is branched into two; one is connected to a circuit 1 through the contact of a relay rl-1 and the other is connected to a switch SW-1. Lines 2 and 3 are the same. Then, outputs of the respective switches SW are connected and connected to the stand-by circuit through a relay rl-s. For example, if the circuit 1 becomes faulty, the relay rl-1 is broken, the switch SW-1 and relay rl-s are closed, and the closed loop 1 is connected to the stand-by circuit. Therefore, if the switch part and stand-by circuit part become faulty, even the disconnection of those faulty parts for repairing exerts no influence upon the in- use circuit.

Connected to 1. Line 2 is similarly branched into two branches, one of which is connected to line m2 through the contact of relay r/-2. The other one is connected to switch 5w-2. Line 3 is similarly branched into two branches, one of which is connected to line 3 through the contact of relay r/-3, and the other connected to switch 8W-a. The outputs of switches 5W-1, 8W-2, and 8W-3 are connected to each other, and the outputs are connected to the protection line via relay rl-3.
