The invention discloses to a method for testing characteristic parameters of a conversion loop of a direct current circuit breaker with extra and ultra-high voltage, which relates to a method for testing the characteristic parameters of the conversion loop of a passive oscillation circuit and an active oscillation circuit of the direct current circuit breaker with the extra and ultra-high voltage. According to different charging voltage (passive) or different charging time (active) of a changeover condenser group, a wave form of the current I of the conversion loop, which is collected and obtained by operating the breaker, is operated, the frequency f and the decay time constant Tau of the conversion loop are respectively obtained, and finally, the characteristic parameters of the conversion loop within a certain range are obtained. The sum of the reactor inductance of the conversion loop (the conversion loop is provided, and a reactor is not provided), the condenser inductance and the line inductance forms the inductance L of the conversion loop, which is equal to 1/(2*pi*f)<2>*C, and the damping resistance R of the conversion loop is equal to 2L/Tau.
