S7, clamping cylinder drive pressure strip and reset, and proceed step S8 or S9;
S8, when tested socket has switch, the switch release mechanism moves down, and pushes said switch key, and switch is broken off, and resets rapidly then; PLC controller control Hi-pot Tester detects leakage current and whether surpasses setting value at the detection voltage of regulation with in detection time carrying out high pressure resistant test between switch the two poles of the earth; If then carry out step S11; If, do not proceed step S9;
S9, identification mechanism start, and tested socket is carried out resetting after the qualified sign, and display screen shows that simultaneously qualified printed words and green indicating lamp are bright; Clamping cylinder starts once more, and pressure strip is pushed down tested socket, and the plug driving mechanism resets, and latch is withdrawed from from tested receptacle sockets;
S10, clamping cylinder reset pressure strip, and said plug-type frock is pulled out, and take out qualified tested socket, and testing process finishes;
S11, testing process finish, and each cylinder resets successively, and display screen shows the defective information of tested socket, and the red alarm pilot lamp lights and hummer sends chimes of doom.
9. the method for the high pressure resistant and break-make Performance Detection of socket according to claim 8 is characterized in that:
Before step S1, also carry out front travel;
Said front travel:, set said detection voltage, resistance test time and leakage current according to the type and the performance standard of tested socket.
10. it is characterized in that according to Claim 8 or 9 described sockets are high pressure resistant and the method for break-make Performance Detection:
Also comprise step S12;
S12, press the warning clear key on the display screen, remove and report to the police, and make system reset; Simultaneously plug-type frock is pulled out from detect station, take out defective socket, isolate disposal, ready for detect next time.
