Transformer Oil Bdv Tester

transformer oil bdv tester is designed and researched by our technical based on the IEC156 and GB507-86’s requirement. It is one fully automatic testing instrument.

In order to satisfy different client's requirement, we design single-cup and three -cup.

TheTransformer Oil Bdv Tester is easy to operate and beautiful in appearance. Adapted the use of automatic digital microcomputer control, the measurement accuracy is high, anti-interference ability is strong, safe and reliable.

1. The Transformer Oil Bdv Tester adapt the microprocessor, it can automatically fulfill the withstand voltage test  with a range of 0～100KV (including boosting, maintaining, mixing, standing, calculation, printing and other operations).

2. large-screen LCD display and prompt by English menu.

3. Easer operation. The machine will automatically complete the withstand voltage test on one cup of sample oil after simple setting by the operator. Breakdown voltage value of 1 to 6 times and recurrent times will be automatically saved. After the test, the thermal printer will print each breakdown voltage value and average value. 

4. Power-down preservation. It can save 100 tested results and displaying current ambient temperature and humidity.

5. Adopt a single-chip microcomputer to boost the voltage at an even speed. The voltage is accurate at 50HZ/60hz, ensuring the whole process easy for control. 

6. The Transformer Oil Bdv Tester has over-voltage, over-current and limit protections to ensure the safety of operators.

7. With the function of displaying the measured temperature and system clock.

1. Output voltage: 0～100KV (optional)

2. Voltage distortion rate: ＜3%

3. Voltage raising speed: 0.5～5 KV/S (adjustable)

4. Standing time: 15min (adjustable)

5. Boosting interval: 5 min (adjustable)

6.Boosting frequency: 1～9 time(s) (optional)

7. Booster capacity: 1.5KVA

1. This equipment shall not be exposed in moist environment.

2. Keep the oil cup and the electrodes clean. Fill the cup with fresh transformer oil for protection during its idle. Check the electrode distance and check the tightness between the electrode tip and electrode bar screw thread before the cup is used again.

1. Oil Cup Cleaning Method

⑴Wipe the electrode surfaces and bars again and again with clean silk cloth.

⑵Adjust the electrode distance with standard gauge.

⑶Use petroleum ether (other organic solvents are forbidden) to clean thrice. Each time shall follow the bellow procedures:

①Pour the petroleum ether into the oil cup till the cup is 1/4～1/3 full.

②Cover the cup mouth with a piece of glass cleaned by petroleum ether. Shake the cup evenly for one minute with certain force.

③Pour away the petroleum ether and dry the cup with a blower for 2~3 minutes.

⑷Use the oil sample to be tested to clean the cup for 1~3 times. 

①Pour the petroleum ether into the oil cup till the cup is 1/4～1/3 full. 

②Cover the cup mouth with a piece of glass cleaned by petroleum ether. Shake the cup evenly for one minute with certain force.

③Pour away the left oil sample and then the test starts.

2. Agitating Blade Cleaning Method

⑴Wipe the agitating blade again and again with clean silk cloth until fine particles are not found on their surfaces. It is forbidden to touch the surfaces with hands.

⑵Use forceps to clamp the blade; put them into petroleum ether and wash.

⑶ Use forceps to clamp the blade and dry them with a blower.

⑷Use forceps to clamp the blade; put them into the oil sample to be tested and wash.

3. Oil Cup Storage

Method 1 Fill the cup with good insulating oil after the test is finished and place it stable.

Method 2 Clean and dry the cup under the above procedures and then put it into a vacuum dryer.

Note: The oil cup and agitating blade shall be cleaned under the above procedures after the first test and tests with poor oil.

4. Common Fault Clearances

⑴ Power light off, screen display off

① Check the plugging of power plug.

② Check the condition of the protector tube inside the power plug.

③ Check the socket electricity.

⑵ No punch through oil cup

① Check inserting of connectors on circuit board.

② Check contacting of cap high-voltage switch.

③ Check attracting of high-voltage contacts.

④ Check break of high-voltage line.

⑶ Light display contrast

① Adjust the potentiometer on the circuit board.

⑷ Printer failure

① Check plugging of printer power line.

② Check plugging of printer data line.
