Abstract

A detection device for internal electronic components of medium and low voltage equipment, used for performing performance tests on electronic components inside medium and low voltage equipment, including a voltage conversion module (110), and the voltage conversion module (110) includes devices sequentially connected to external industrial voltage sources The power input terminal (111), the transformation unit (112) that converts the voltage of the power supply input terminal (111) into different voltage values, and selects one of the different voltage values ​​converted by the transformation unit (112) as The first selection switch (113) for the output voltage, the rectification and filtering unit (114) for converting the AC voltage selected by the first selection switch (113) into a DC voltage, and the optional rectification unit (114) with the first selection switch (113) or The voltage output terminal (117) connected to the filtering unit (114). The above detection device can output AC voltage, DC voltage, AC current and DC current of different values, and can meet various inspection requirements of different electronic components in medium and low voltage equipment.

Description

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...
