The present invention relates to an individual blocking and monitoring apparatus for a traction motor in an extra-large diesel-electric locomotive, which can shorten maintenance work time and efficiently manage related personnel. The individual blocking and monitoring apparatus for a traction motor in an extra-large diesel-electric locomotive according to the present invention comprises: a blocking switch which is additionally installed in a series relay and, when grounding is generated in an arbitrary traction motor due to flashover, blocks driving of the traction motor by blocking the series relay related to the driving of the traction motor; a current sensor which measures currents flowing in circuits of a plurality of traction motors, respectively; a main control unit which receives current values measured by the current sensor, respectively, to compare the values with an allowable reference value and outputs a warning signal when the measured current values deviate from the allowable reference value; and a display device which receives the current value of each traction motor measured by the current sensor through the main control unit to display the value on a screen and displays data of traction motors, related diagrams, graph materials, and the like, on the screen.

    본 발명은 특대형 디젤전기기관차 견인전동기의 개별 차단 및 모니터링 장치에 관한 것이다. 본 발명에 따른 특대형 디젤전기기관차 견인전동기의 개별 차단 및 모니터링 장치는, 직렬 계전기에 보조적으로 설치되며, 임의의 견인전동기가 플래시오버로 인한 접지 발생 시, 해당 견인전동기의 구동과 관련된 직렬 계전기를 차단함으로써 해당 견인전동기의 구동을 차단하는 차단 스위치와; 다수의 견인전동기의 회로에 흐르는 전류를 각각 측정하는 전류 센서와; 전류 센서로부터 측정된 전류값을 각각 수신하여 허용 기준치와 비교하고, 측정 전류값이 허용 기준치를 벗어나는 경우 경보 신호를 출력하는 메인 제어부; 및 전류 센서로부터 측정된 각 견인전동기의 전류값을 상기 메인 제어부를 통해 수신하여 화면에 표시하는 한편, 견인전동기의 데이터와, 관련 도표 및 그래프 자료 등을 화면에 표시하는 표시 장치를 포함한다.
