Principle of work of the present invention is as follows:
Referring to Fig. 1 to Fig. 5, the mode of the alternative manual stay cord of transmission of mode of operation that the present invention adopts automated machine to rotate is carried out the disjunction disconnector.
At first the laboratory technician connects the power supply of whole operating means, and, according to disconnector model to be tested, determines whether to need to overturn test product erecting frame mounting platform 220, so that disconnector model to be tested is installed.If need upset test product erecting frame mounting platform 220, the platform on point touching screen controller 110 is adjusted button, upset drives solenoid valve F33 obtain electric and work, synchronously turn to extreme lower position downwards by oscillating cylinder 340 and synchronous upset test product erecting frame mounting platform 220 and the cylinder mounting platform 600 of driving of telescopic cylinder 350, after upset test product erecting frame mounting platform 220 and 600 upsets of cylinder mounting platform put in place, disconnector to be tested is installed on test product erecting frame 221, and divide-shut brake is connected with the rotating shaft of disconnector to be tested with the push rod 311 of cylinder 310, in disconnector installation process to be tested, can regulate by manual fine-tuning mechanism 210 position of test product erecting frame 221.After disconnector to be tested installs, point touching screen controller 110 upper mounting plates are adjusted button, upset drives solenoid valve F33 obtain electric and work, and by oscillating cylinder 340 and telescopic cylinder 350, synchronously drives upset test product erecting frame mounting platform 220 and cylinder mounting platform 600 synchronously to turn to testing position downwards and gets final product.
Disconnector to be tested is after testing position, at first by the control device initialization of 110 pairs of whole operating means of touch screen controller, enter the setting parameter step after initialization, in the setting parameter step, the test parameterss such as disjunction direction, disconnector specification, conduction time are set, setting parameter well enters test later.
For single test, at first whether 1000 pairs of master controllers close a floodgate and are judged, if do not close a floodgate, be back to the setting parameter step, if close a floodgate, enter the combined floodgate step, in the combined floodgate step, divide-shut brake drives solenoid valve F6 to obtain the electric combined floodgate duty that enters, to cylinder 310 air feed for divide-shut brake, divide-shut brake rotates and is closed a floodgate with the push rod 311 promotions disconnector rotating shaft to be tested of cylinder 310, after disconnector to be tested closes a floodgate, master controller 1000 judges whether to enter test, if do not enter test, divide-shut brake drives solenoid valve F6 to the reverse air feed of cylinder 310 for divide-shut brake, divide-shut brake promotes disconnector rotating shaft to be tested with the push rod 311 of cylinder 310 and rotates backward and carry out separating brake, enter the setting parameter step after separating brake.If proceed test, master controller 100 judges whether to need to adjust the position of upset test product erecting frame mounting platform 220 and cylinder mounting platform 600, if do not need, is back to the combined floodgate step; If need to adjust the position of upset test product erecting frame mounting platform 220 and cylinder mounting platform 600, master controller 1000 makes upset drive solenoid valve F33 obtain electric and work, by oscillating cylinder 340 and synchronous upset test product erecting frame mounting platform 220 and cylinder mounting platform 600 positions of driving of telescopic cylinder 350, after adjust position, enter the test preliminary step.After entering the test preliminary step, at first master controller 1000 detects whether make-and-break signal is arranged, if having, delay circuit work in master controller 1000, enter test time delay step, if without make-and-break signal, turns back to the test preliminary step and checked.After closing time arrives, it is electric to the reverse air feed of cylinder 310 for divide-shut brake that divide-shut brake drives solenoid valve F6 to obtain, divide-shut brake promotes disconnector rotating shaft to be tested with the push rod 311 of cylinder 310 and rotates backward and carry out separating brake, test completes, after single test completes, be back to the setting parameter step, enter test next time.If test once under not having, finish test.
For test of many times, after setting parameter is good, master controller 1000 is given test solenoid valve F4 energising, test solenoid valve F4 action, after master controller 1000 detects test solenoid valve F4 actuating signal, by touch screen controller 110 input test number (TN)s, then start test, in process of the test, divide-shut brake drives solenoid valve F6 to obtain electricly to divide-shut brake, with cylinder 310, repeatedly to carry out forward and reverse air feed, divide-shut brake repeatedly carries out forward and rotates backward with the push rod 311 promotion disconnector rotating shaft to be tested of cylinder 310, disconnector carries out combined floodgate and minute brake test repeatedly, 1000 pairs of test number (TN)s of master controller are counted, judge whether to reach the test number (TN) of setting, if do not reach, divide-shut brake drives solenoid valve F6 to obtain electricly to divide-shut brake, with cylinder 310, repeatedly to carry out forward and reverse air feed, if reach the test number (TN) of setting, divide-shut brake drives the solenoid valve dead electricity, test completes.
In process of the test, large isolation solenoid valve F3, septulum are as shown in table 1 from the steering logic of solenoid valve F5 and test solenoid valve F4;
Table 1
The operating means of this robotization is changed into mechanical disjunction mode by traditional disconnector disjunction mode by artificial disjunction mode, reach the short form test installation procedure, reduce operating personnel's risk, the impact that in less process of the test, human factor produces test, also can control conduction time and operating frequency exactly by control device.
