Load test device for rail vehicle power panels

The invention relates to a load test device for rail vehicle power panels. The load test device is composed of a connecting socket, a power supply 5V load circuit, a power supply 15V load circuit, and a power supply 24V load circuit. Commonly-used chip resistors, light emitting diodes and toggle switches are welded to a printed circuit board through soldering and are correspondingly connected with output voltages of the circuit board through the connecting socket. The load resistance value is set according to the value of current flowing through each circuit of a power panel, the switches are shifted up and down to switch on or off the resistors, load test of each circuit is indicated by on-off of the corresponding light emitting diode, and therefore, performance test can be completed quickly. Multiple load circuits of a power panel can be set precisely, the load resistance can be adjusted flexibly according to the magnitude of current of the power panel, and whether the output voltage of each circuit of the power panel meets the requirement can be detected. The load test device of the invention has a simple structure and high universality, and is space-saving.
