As shown in fig. 2, the curve (r) can be used for judging the adjusting performance of the oil supply shutoff valve of 2r/min of the hydraulic barring; the curve II can be used for judging the stability performance of the hydraulic barring at 2 r/min; the curve (c) can be used for judging the switching function of the manual switching valve 11 of the rotating speed; the curve (iv) can be used for judging the adjustment performance of the oil supply shutoff valve at 20 r/min; the plot 20 back in fig. 2 can be used to judge the performance of the power oil supply isolation valve 22.

controlling a power oil supply isolation valve of a hydraulic barring of the hydraulic barring to be closed so as to stop the rotating speed output of the hydraulic barring to a rotor,
and after the hydraulic barring stops outputting the rotating speed of the rotor, acquiring shutdown information of the closed hydraulic barring.
9. The on-board test method for the hydraulic panel of the nuclear power plant according to any one of claims 1 to 8, wherein the first operation information is: the rotor time information and the rotating speed information after the hydraulic barring enters the first oil way;
the second operation information is: the rotor time information and the rotating speed information after the hydraulic barring enters the second oil way;
the shutdown information is as follows: time information and rotational speed information of a rotor of the hydraulic barring.
10. The utility model provides a nuclear power station hydraulic pressure barring on-load test device which characterized in that includes:
the test preparation unit is used for executing preparation before a test to enable a hydraulic barring oil supply system of the steam turbine generator unit to enter a state to be tested;
the forced unit is used for forcing a power oil control valve of the hydraulic barring gear to carry out logic signal forcing and forcing a rotating speed switching valve of the hydraulic barring gear so as to enable the hydraulic barring gear to be in an oil path switching state between a first oil path and a second oil path;
the control unit is used for controlling the hydraulic jigger to respectively enter the first oil way and the second oil way;
the information acquisition unit is used for acquiring first operation information after the hydraulic jigger enters a first oil way and second operation information after a second oil way;
the closing unit is used for controlling the hydraulic jigger to be closed and acquiring shutdown information after the hydraulic jigger is closed;
the curve acquisition unit is used for acquiring a load test curve of the hydraulic jigger according to the first operation information, the second operation information and the shutdown information;
and the performance judging unit is used for judging the load performance of the hydraulic jigger according to the load test curve of the hydraulic jigger.
