Direct-current durability parallel full-automatic test device

The utility model discloses a direct-current durability parallel full-automatic test device, which is characterized in that when an insulating material test object is subjected to a durability test, a high-voltage direct-current power supply is switched on, so that the two ends of the insulating material test object reach test voltage, and if a certain insulating material test object is broken down and a fuse wire is fused in the test process, the test object cannot be damaged. When the insulation material test sample is broken down, the insulation material test sample is broken down, so that the broken-down insulation material test sample exits the circuit connection, meanwhile, the potential indicator corresponding to the broken-down test sample branch outputs a low-potential signal and transmits the low-potential signal to the signal selector, the signal selector outputs a corresponding test sample branch sequence number to the controller, and the controller outputs a control signal to adjust the voltage o
