A low resistance 2 is connected in parallel to the electromagnetic coil 1, one end of the 1titt coil 1 is connected to one power supply terminal 4 via a power supply switch 3, and the other end is connected to the other power supply terminal 5. has been done. Further, the electromagnetic coil l
An output switch 6 is attached to which a movable contact 6a and a fixed contact 6b are opened and closed by electromagnetic force, and both ends of the output switch 6 are connected to output terminals 7 and 8.

みに、これらの諸元は容易に実現できる数値である。Note that while the non-resistance of metal steel is on the order of 1041 Qm, that of the superconducting material forming the electromagnetic coil 1 reaches as much as 10'' Ωm, and - numerically, the DC resistance of the coil portion is zero. In the following explanation, it is assumed that the inductance of the electromagnetic coil 1 is 1 mH, and the value of the sum of the DC resistance of the low resistance 2 itself, the DC resistance of the electromagnetic coil 1, and the DC resistance of the connection part is 1Ωm. Incidentally, these specifications are numerical values that can be easily achieved.
以上のように構成された時限継電装置についてその動作

電流が流れた時点で給電スイッチ３の投入を解除する。To explain the operation of the time relay device configured as above, first, the power supply switch 3 is turned on to temporarily supply current to the electromagnetic coil 1, and when a sufficient current flows through the electromagnetic coil 1, to release the power supply switch 3.

時定数はここで示した例では１ （秒）である。At this point, the movable contact 6a of the output switch 6 is in contact with the fixed contact 6b due to the electromagnetic force from the electromagnetic coil 1. Even if the power supply via the power supply switch 3 is cut off, a circulating current flows through the closed circuit formed by the electromagnetic coil 1 and the low resistance 2, and its time constant is 1 (second) in the example shown here.

The output switch 6 can be reset after one second or more has elapsed.
