Claims

[Claims for Utility Model Registration] The cutting operation and the closing operation of the cutting switch are performed via a link mechanism by the spring forces of the cutting spring and the closing spring, respectively, and the stored energy of the closing spring is applied. In an operation control device for a shield and disconnector operated by a spring energy storage motor, there is a closing command switch that issues a closing command, and an energization process in the closing operation process of the shield and disconnector in response to the closing command from the closing command switch. a closing circuit for controlling the closing operation, including a normally closed contact of a repeat prevention relay, and a closing coil connected in series to the closing command switch via the normally closed contact of the repeat prevention relay; It includes a shear disconnection command switch that issues a disconnection command, and a shear disconnection circuit that controls the shear disconnection operation, including a tripping coil connected in series to the sheath disconnection command switch, and a shear disconnection circuit that controls the shear disconnection operation; A first voltage detection circuit is connected in parallel with the switch and in series with the closing coil, and in parallel with the shear disconnection command switch of the shear disconnection circuit and in series with the tripping coil. What is claimed is: 1. An operation control device for a shield disconnector, characterized in that it is configured by connecting a second voltage detection circuit.
