Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a testing device for surge voltage immunity. Background Art

[0002] Surge is also called sudden wave. As the name suggests, it is an instantaneous overvoltage that exceeds the normal working voltage. In electronic design, surge mainly refers to the strong pulse generated at the moment the power is just turned on. The linearity of the circuit itself may be higher than the pulse of the power supply itself; or because the power supply or other parts of the circuit are interfered by itself or external sharp pulses, it is called surge. It is very likely to burn out the circuit at the moment of surge. Therefore, it is very necessary to perform surge voltage immunity test on the electric lamps used. In the existing detection device, it is not accurate to conduct a test by moving the distance between the electric lamp and the surge generator. It is necessary to test the immunity results of the electric lamp under different surge voltages.

[0003] Therefore, a test device for surge voltage immunity is proposed. Utility Model Content
