Integrated track circuit shunt resistor emulator

Abstract

The utility model discloses integrated track circuit shunt resistance simulator, including clamp, one end of clamp is installed with rotation axis, and the bottom of clamp is installed with chuck, and one side of circuit board is installed with dismounting structure, and the dismounting structure includes the first fixed screw of one side of clamp installation. The utility model discloses through adopting the grounding clamp of pure copper 800A large current, and the clamping force is big, and the effect is good, and the volume is not big, and the weight is moderate, and it is convenient to carry, on the circuit design, in order to further simplify circuit, the resistance box and the table pen are banned, and directly using the soft cable with resistance makes the left and right sides steel rail constitute wheel pair resistance value simulation loop, and the cable adopts low resistance silicon rubber double -layer sheath 2.5 square millimeter diameter soft cable, compared with the current traditional resistance box and table pen mode, and the internal resistance is lower, and the life is longer, and it is more convenient to use, in the switching of resistance value, and the switch adopts the switch of two wave bands of large current low internal resistance, and the resistance adopts the high -power high -precision instrument non -inductive resistance.
