본 발명에 따른 팬터그래프 접촉저항 측정장치는, 복수의 급전전극에 측정전류를 공급하는 측정 전원부; 복수의 급전전극과 측정 전원부 사이에 배치되고, 측정 전원부에서 공급된 측정전류에 대해서 상이한 전류경로를 형성하도록 제어되는 급전 스위치부 및 수전 스위치부; 및 전류경로 상의 급전전극 양단의 전압과 측정전류에 기초하여 급전전극과 수전전극 사이의 접촉저항을 각각 산출하는 산출부를 포함하여 구성된다.이에 따라, 본 발명은, 측정전류의 전류경로를 달리한 다수의 측정방식을 통하여 팬터그래프 충전방식에서 간단한 구조로도 급전전극과 수전전극 간의 접촉저항을 측정함과 동시에 접촉불량이 발생하는 전극을 식별하여 손쉽게 접촉불량을 해결하도록 함으로써, 접촉불량에 의한 화재 및 감전사고를 사전에 예방할 수 있는 효과가 있다.

    According to the present invention, provided is a pantograph contact resistance measuring device, which comprises: a measurement power supply unit supplying a measurement current to a plurality of power supply electrodes; a power supply switch unit and a power receiving switch unit disposed between the plurality of power supply electrodes and the measurement power supply unit and controlled to form a different current path for the measurement current supplied from the measurement power supply unit; and a calculation unit calculating a contact resistance between the power supply electrode and the power receiving electrode based on a voltage and the measurement current of both ends of the power supply electrode on a current path. Accordingly, the device of the present invention measures the contact resistance between the power supply electrode and the power receiving electrode even with a simple structure in the pantograph charging method through a number of measurement methods in which the current path of the measured current is different. By identifying the electrode where a contact failure occurs to easily solve the contact failure, fire and electric shock accidents by the contact failure can be prevented in advance.
