METHOD AND DEVICE FOR AC WITHSTAND VOLTAGE TEST

Japanese Patent JP2010008304

A

To apply a large voltage cross terminals without increasing a voltage to ground.

A switch 7 including a pair of terminals and a capacitor 8 connected in parallel with the terminal are provided inside a switch device 6. A test AC voltage generator 1 and a test AC voltage generator 2 are connected to two external terminals of the switch device 6, respectively. A voltage is supplied to the primary side of the test AC voltage generator 1 connected to the one terminal via a voltage regulator 3 from a power generator 5, and a compensation reactor 4 is further connected thereto. The power generator 5 is directly connected to the primary side of the test AC voltage generator 2 connected to the terminal at the opposite side. The power generator 5 is connected so that a phase of the test AC voltage generator 2 at the terminal at the opposite side is shifted by 180 degrees from a phase of the output voltage of the test AC voltage generator 1 at the one terminal. The output voltage of the power generator 5 is commonly supplied as the primary side voltage of the test AC voltage generator 1 and the test AC voltage generator 2.
