technical field [0001] The invention relates to the field of power transmission equipment of a power system, in particular to a detection device for electronic components inside a medium and low voltage equipment for detecting electronic components inside the medium and low voltage equipment. Background technique [0002] The detection devices used in the inspection of internal electronic components in traditional medium and low voltage equipment have less detection functions, and a single detection device cannot meet the inspection requirements of different electronic components at the same time. For example, when some electronic components to be inspected need to be tested Input the detection voltage of AC220V, while other electronic components need to input the detection voltage of DC6V when testing. In this case, it is usually necessary to provide multiple detection devices at the same time to test the electronic components inside the medium and low voltage equipment, wh...
