The invention belongs to the field of circuit function element tests, and particularly relates to a damping capacitor operation test system. The first diode valve and the damping resistor which are connected in parallel with the two ends of the charging thyristor valve are arranged, so that the energy part of the damping capacitor of the test object can return to a direct-current power supply, the voltage at the two ends of the charging thyristor valve is rapidly reduced, and the charging thyristor valve is rapidly cut off; therefore, the charging completion efficiency and the overall test efficiency can be improved; the damping resistor not only can shorten the recovery time of the charging thyristor valve under the condition of higher voltage change speed, so that the charging process of the damping capacitor of the test object in the damping capacitor operation test system is more in line with the actual working condition, but also can control the speed of the energy return process; moreover, the voltage a
