摘要： PURPOSE: To achieve an automatic connection of a tester to the control center while automatically indicating the state and results of the testing by transmitting the contents of a development connection diagram to the tester through the transmission of information utilizing a computer.
CONSTITUTION: A main circuit load terminal 14, a control circuit terminal 15 and a test circuit switch 10 are connected to a control center 8 with a main circuit power source unit 9 and a connection cable 12. A testing circuit forms a voltage withstand testing circuit and a sequence testing circuit with a circuit changeover switch 16 and the selection is made by a tester's operation. When the voltage withstand testing circuit position is selected and operated, a circuit selection repeater 21 fails to work and the control center 8 is connected to the voltage withstand tester 11 to enable the execution of a voltage withstand testing. When the sequence testing circuit position is selected and operated, the circuit selection repeater 21 works the control center 8 is connected to a circuit composer 6. The circuit composer 6 operates a circuit composition repeater 23 by information on connection in the design to compose a circuit which is connected to an external equipment provided on a sequence tester 7.

摘要： PURPOSE:To enable a fixed pin easily drawn out from the position fixed metal, by means of turning an interlocking pin, when a fixed device of the breaker, that is used and contained in the enclosed switchboard, comes in a firm engagement due to a vibration of the breaker switching operation. CONSTITUTION:When a fixed pin 14, having handling rod 11, goes into and comes out from an operating position hole 21 or a test position hole 22, for constructing a clearance between a part of position fixed metal 15 and the fixed pin corresponding to those of the above holes, a slit part 14A is provided partially in the fixed pin. Consequently, even for a firm engagement caused by a vibration of switching operation of the breaker, construction of the clearance, made between the slit part and the position fixed metal by means of turning the interlocking pin, will enable the fixed pin easilly pull out from the position fixed metal.
