High Voltage Cup For Insulating Oil Withstａnd Voltage Test

I. General description:
Insulating oil pressure test cup is special test ceramic pressure test high voltage insulating oil, corresponding glass wall ends with copper electrode for 0-80KV high voltage AC, with high compactness of high voltage Features should not be broken.

II.The main technical parameters:
1. power power: AC, 220V, 50Hz
2. measuring range: AC 0-80KV
3. room temperature: 0-35
4. relative humidity: less than 75%

2. Oil Cup Cleaning Method

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

⑵ Adjust the electrode distance with standard gauge.

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

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

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

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

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

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

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

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