1, input power supply: connect the grounding of the oil pressure tester, insert 220V AC power supply, check the power supply is correct. Adjust the distance between the two electrodes of the oil cup to 2.5mm, rotate the feeler rod at one end of the oil cup shaft rod counterclockwise, adjust the other end electrode in the center position, tighten the screw locking the shaft rod, take the feeler rod between the two electrodes close the two electrodes, lock the screw, remove the feeler rod, rotate clockwise in the original shaft rod.
2. Clean the oil cup, place a clean magnetic oscillator in the oil cup, fill it with the prepared oil sample, remove the high pressure cover, place the oil cup between the two high pressure columns in the high pressure chamber, and place the high pressure cover on the cover smoothly and press the switch. Then it is the scheduled setting of the insulating oil pressure tester. Press the "test value" button when testing, stirring, standing, boosting and printing functions will be in the order of fixed values. Press the "stop" button in the process of boosting, it will stop boosting, and the value on the digital display is the high voltage output value of the high voltage terminal at this time.
After 3, booster sample breakdown, acoustic remind continuous sound "di" is a short 20 seconds, two "di" after two short sound, the sixth "di", a long a short sound, the seventh "di" is a long sound 2 short, average stay after the show "di" non-stop ringing for 20 seconds, if it's not acoustic warning, click on the voice control key to enter relating to remind, optical indicator, The number of flashes is the same as the number of "beep" sound. Pressing the voice control button again is invalid. Keep the light control unchanged, and the voice control will be effective when the power is turned on again.
4. After the test, if you want to view the data again, press "Display" and "print". These two keys belong to repeated use. When you press "Print", the voltage value will not be printed repeatedly. When the "reset" button is pressed, the word "OCPU" displayed in English means the initial waiting state after the reset is in place, referred to as the initial state or OCPU state. If the "Reset" button is pressed in the test boost process, it will not enter the initial state. It is the same as the situation in the breakdown of oil sample. If continuously press the "reset" key, it will be confirmed as "reset" and enter the initial state.
5, start waiting: when the power is ON, the machine enters the self-checking state, the printer responds with the indicator light ON, and the display screen shows the words OCPU. If the voltage regulator is not at zero, the display word DIJJ indicates the reset process. The drop indicator light is ON, and the initial OCPU waiting state is displayed after falling to zero.
6. Click the "test value" key and start to run according to the preset value; The stirring indicator light is on and the magnetic oscillator rotates rapidly. One di digit on the display screen shows the number of DI times, and the last three digits show the stirring time. Mixer mixing, oscillator stop light, a quiet place indicator to let stand, after lights out, switching, pressure indicator, and into the display synchronous booster, the display screen after three digital display for voltage (00.0 KV) after being sample breakdown, boosting the power automatic brake, a stop display 5 seconds, the printer to print time, voltage value.
7. Under the voltage regulator, the drop indicator light is on, and the mixing indicator light is on DI second test begins. At the same time, the printing and display screen display breakdown voltage, display secondary value flashing, and voice control reminder; After the voltage regulator returns to zero, the drop indicator is off, the display stops flashing, and the voice control disappears. Then di is tested twice. After all test times are run, the screen displays the average of the total times, such as a24.3kV for only one test, f24.3kV for six tests; Then print the average voltage, the oil sample test is completed, at this time can be repeated display, print, press the reset button, all data disappear. After taking out the oil sample in OPCU state, the new oil sample can be replaced and tested again. After testing, the power supply is turned OFF in the OFF position under reset state.
