FREQEUNCY VOLTAGE CONVERTING MODULE USED IN CONTROL SYSTEM OF NUCLEAR PLANT

摘要

A frequency voltage converting module used in a control system of a nuclear plant is provided to facilitate a test and an operation without being separated from a system by implementing a test mode on the system. A frequency voltage converting module used in a control system of a nuclear plant includes a connector(10), a first channel unit(20), a second channel unit(30), and a DC/DC converting unit(40). The connector receives power from the outside and inputs and outputs an input signal and an output signal separately. The first channel unit outputs a first voltage signal to the connector by converting a first frequency input signal according to a rotation of a coolant circulating pump into the first voltage signal. The second channel unit outputs a second voltage signal to the connector by converting a second frequency input signal according to the rotation of the coolant circulating pump into the second voltage signal. The first and second frequency input signals are inputted from the connector. The DC/DC converting unit supplies the first channel unit and the second channel unit with power by converting the operation power into the power of different intensity.
