Method of using dielectric oil dielectric strength tester
- Clicks:1700 Release time:2011/12/21
The fully automatic insulating oil dielectric strength tester uses an AC reversible electric voltage regulator to automatically boost evenly. When the insulating oil breaks down, the instrument protection system automatically cuts off the working power. The discharge spark is small at the time of breakdown, and no significant free carbon is generated. The test was carried out for 6 consecutive times with low dispersibility and no need to stir between the electrodes. The oil cup is placed in a closed glass cover with an interlocking device. When the oil cup cover is opened, the high-voltage power supply can be automatically cut off, and no stored charge is stored to ensure personal safety. Here, the electrical tester is reminded to pay attention to the following methods when using the transformer oil dielectric strength tester:
※ The working power of the fully automatic insulating oil dielectric strength tester is AC220V, and the grounding end of the outer casing must be connected to the standard ground wire (completed before power-on).
※ Carefully install the inspection oil cup and pay attention to the pole axis. Adjust the small plate electrode spacing to 2.5mm.
※ Turn on the “Power Switch†and the power indicator will light. At this time, the voltmeter displays “00.0â€, indicating that the instrument is normal.
※Before boosting, you must first step down (if the regulator is not in the zero position), then perform the boost test, otherwise the instrument will refuse to operate.
※Inject the transformer oil into the oil cup twice, then fill the oil sample with the oil cup, place the oil cup on the electrode holder, close the oil cup cover, and press the interlock switch (do not press the interlock switch instrument to refuse the action). ).
※ Let stand for 10 to 15 minutes to remove air bubbles.
※ The “boost switch†can be boosted automatically. When the oil breaks down, the overcurrent protection system device cuts off the high voltage within 0.02 seconds, and the digital value displayed at this time is the breakdown voltage value of the oil.
※Pulse the “buck switchâ€, the regulator will automatically return to zero, and the second test can be done after 5 minutes.
※ During the test, the digital display of the fully automatic insulating oil dielectric strength tester has not reached 60KV, but the voltage regulator turntable has encountered the limit switch. This phenomenon is caused by insufficient external voltage (not related to the instrument).
※In the test process, if the automatic insulation oil dielectric strength tester is in abnormal condition, press the “stop switch†to forcibly cut off the power supply (restart “stop†to reset).

Fourth, the panel description
2. Take the oil sample 2.1 Adjust the distance between the two electrodes of the oil cup at 2.5mm; unscrew the feeler rod at one end of the oil cup shaft counterclockwise, adjust the other end electrode to the neutral position, and screw the screw that locks the shaft. Tightly, take the feeler rod and press the two electrodes between the two electrodes, lock the screw and take out the feeler gauge, and turn it clockwise in the original shaft, as shown in Figure 2.
3. Scheduled settings 3.1 The set value has a total of 6 pre-selected disks as shown in Figure 3:
23 indicates the stirring time setting, 2 indicates that the tens place 3 indicates the single digit, and the 1 minute 39 seconds indicates that the number is 99, that is, 60 seconds + 39 seconds.
456 indicates the rest time setting, and 4 indicates "minute". The digit 5 ​​indicates "second". The tens digit 6 indicates the "second" digit, and the 10 minute 39 seconds indicates that the number is 999, that is, 9 minutes + 60 seconds + 39 seconds.
Example: According to the test requirements, the oil sample should be allowed to stand for more than ten minutes. After the second time, the oil should be allowed to stand for more than five minutes, and the stirring can be set automatically.
4. There are 6 function key operation function keys, which are jog keys. Click to respond to work. Figure 4
2 Press the "Stop" button during the boosting process, the boost will stop. The value on the digital display is the high voltage output of the high voltage terminal at this time, which can be kept in sync. Press and hold this button to adjust the low and high voltage output values. , according to the status, just press the measured value button to continue to resume operation.
After 3* times of boosting oil sample breakdown, the voice control reminds the continuous "嘀" for a short sound of 20 seconds, the second time after the "嘀" two short sounds, the sixth "嘀", a long sound and a short sound, the seventh The second "嘀" has a long sound and two short sounds. After the average value is displayed, the "嘀" is uninterrupted for 20 seconds. If you do not need the voice control reminder, press the voice control button to enter the light control reminder. The light control indicator lights up, and the number of flashes is the same. The number of times the "嘀" sound is the same, press the voice control button again, keep the light control unchanged, and the voice control needs to be activated when the power is turned on again.
4 After the test, if you want to view the data again, press the "Display" and "Print" buttons. These two buttons are used repeatedly. Press the "Display" button once to display the test value once, until the average value is displayed, and the display is repeated. When the "Print" button is pressed, the printing voltage value is repeated and the time is not printed.
5 When the "Reset" button is pressed, the word "OCPU" is displayed as the initial waiting state after the reset is in place, which is referred to as the initial state or the OCPU state. Pressing the "Reset" button during the test boosting process will not enter the initial state. As in the case of breakdown of the oil sample, the continuous operation does not change the original operating state. For example, if the "Reset" button is pressed continuously, it is confirmed that it is "Reset" and then enters the initial state.
5. Power on and wait for the power switch to be "ON", the machine enters the self-test state, the printer response indicator lights up, the display shows the OCPU word, if the voltage regulator is not at the zero position, the DIJJ word is displayed, indicating the reset process, the down indicator light is on, After falling to zero, it is displayed as the OCPU initial wait state.
6. Measure the jog "measured value" button, start to run according to the preset value; the stirring indicator lights up and the magnetic vibrator rotates quickly, the display * digits display * times, the last three shows the stirring time; the stirring is completed, the vibrator Stop stirring indicator light off, the static indicator light starts to stand still, after the indicator light is off, the closing and boosting indicators are on, and the display synchronous boost is activated. At this time, the three digits of the display are displayed as voltage (00.0KV). After the breakdown, the boost power supply is automatically opened, the display stops displaying for 5 seconds, the printer prints the time and voltage value; the regulator drops, the down indicator lights, the stirring indicator lights up, the second test starts, and the print and display display Breakdown voltage, display frequency value flashes, voice control reminder; after the voltage regulator returns to zero, the falling indicator light is off, the display stops flashing, the voice control disappears, and then the second test; after all the test times are completed, the display shows the total number of times The average value is expressed in English letters (A, B, C, D, E, F, G, H, y). If it is tested only once, it is displayed as A24.3KV, if the test is displayed six times as F24.3KV; then the voltage is printed. Mean oil sample test is completed, the display can be repeated at this time, the printing press reset key, all the data disappear. When the oil sample is taken out in the OPCU state, the new oil sample can be replaced and tested again. After the test is completed, the power is turned off in the OFF position. The test light operation process is shown in Figure 5:
Stirring light is on during the stirring time
The standing indicator lights up during the rest time
During the boosting process, the rising and closing indicators are on.
After the oil sample is excited, the regulator will return to zero, the falling indicator light will be on and the next stirring time will start. After the stirring indicator light is exposed, the light control can be selected. The light control indicator is bright. 6. Safety precautions 1.
