SYSTEM FOR DETECTING VOLTAGE AND CURRENT OF RAILROAD CAR

摘要

PURPOSE: A system for detecting the voltage and current of a railroad car is provided to make construction easy and inexpensive by commonly using circuits and devices of the same or similar functions. CONSTITUTION: A system for detecting the voltage and current of a railroad car comprises terminals(110) installed in a terminal box(100), made of a metal capable of blocking the external noise and transmitting the signals sensed by voltage and current sensors(10) of respective electric devices and a transducer(200) having many channels and making a measurement system recognize the sensed signals by changing the current or voltage transmitted from the terminals.
