The connection of the first test lead, one end of one end of the normally opened contact of the 3rd relay and the normally opened contact of the 4th relay is uniformly resistance to
Second test lead of pressure tester, the other end of the normally opened contact of the first relay, the normally opened contact of the second relay it is another
The other end of the normally opened contact at end, the other end of the normally opened contact of the 3rd relay and the 4th relay is used to connection and opened
Test point on powered-down source.
The utility model is further arranged to：The one end of the normally opened contact of first relay away from the first test lead connects
In the test point for being connected on the live wire of Switching Power Supply and zero line side.
The utility model is further arranged to：The one end of the normally opened contact of second relay away from the first test lead and
The one end of normally opened contact away from the second test lead of 3rd relay is both connected in the ground wire housing test point of Switching Power Supply.
The utility model is further arranged to：The one end of the normally opened contact of 4th relay away from the first test lead connects
In the test point for being connected on the output end of Switching Power Supply.
The utility model tool has the advantage that：Relay is controlled by MCU controllers so that for voltage-withstand test
Instrument carries out voltage-withstand test to the test point in Switching Power Supply, it is to avoid need manually control Hi-pot Tester in Switching Power Supply
Test point is attached control, improves the operating process of the voltage-withstand test in production process to Switching Power Supply, further improves
Testing efficiency.
