Automotive supercapacitor withstand voltage insulation test

Addtime:2018-12-27 Hits

  Applications: New energy vehicle super capacitor production line, laboratory, process research department and upstream and downstream parts suppliers

  Specific requirements: After the super capacitor is installed as a finished product, it is required to test AC withstand voltage and DC withstand voltage. The AC withstand voltage is between the positive and negative electrodes, and the DC withstand voltage includes three items: “positive to negative”, “positive to outer” and “negative to outer”.

  Product Type: AN9635HS or 9636HS (built-in three-channel version and need to add a discharge resistor)

  1, the program background

  After the supercapacitor is finished, the AC withstand voltage and DC withstand voltage test are required. The AC withstand voltage is between the positive and negative poles. The DC withstand voltage includes three items: “positive to negative”, “positive to outer” and “negative to outer” (specific test time and voltage level according to customer's own process requirements, but It is worth noting that during the test of the DC withstand voltage between the positive and negative electrodes, the capacitor will be fully charged before the withstand voltage test and the charging time is generally longer between 150-250S. In addition, the test must be discharged to avoid the tester. The operation is matched to the positive and negative poles and is hit)

  2, sales opportunities

  With the built-in three-channel function of the 9635HS or 9636HS, it can meet the test of its three DC withstand voltages, and it can be discharged directly after the discharge resistor is tested to ensure the safety of the operator.

  3, the program detailed

  When AC withstand voltage, A output high voltage B is used as the loop. In the DC withstand voltage test, "positive to negative" is A output high voltage B as the loop, "positive to outer casing" is A output high voltage B as the loop and "negative to outer casing" is B As the high voltage C as a loop, after the end of the test, the internal relay is switched to discharge the discharge resistor through the loop formed by AB.
