Coil current monitoring apparatus for control element drive mechanism

The subject innovation relates to a coil current monitoring device of the control rod drive system. Coil current monitoring device of the control rod driving apparatus according to an embodiment of the present design is the coil current monitoring sensor for sensing the current flowing through the control rod drive coil cable; Said coils supplied with a voltage required for driving the current-monitoring sensor, and the control card to which a detection signal from the coil current sensor monitoring input; Connector to reduce the pressure in the voltage applied to the coil current sensor monitoring from the control card; And it can be coupled to the connector and includes a check measurement terminals for measuring the signal value detected by the sensor coil current monitoring kit formed. Coil current monitoring device of the control rod driving apparatus according to the present invention has an advantage capable of providing a check point, which can accurately measure the signal when the control rod control system failure. Control rod drive device, the coil current, the sensor
