Detailed description of the invention
The utility model is described in more detail with embodiment below in conjunction with the accompanying drawings.
Current converter station tubular mother connects the embodiment of the detection device of gold utensil welding quality
Pipe mother connects gold utensil and is connected the corresponding up and down flexible circuit conductor of each bar, and the other end of these two the most corresponding flexible circuit conductors embraces folder by auxiliary tube mother, and flexible circuit conductor is embraced the carrying out at folder welds, and in the present embodiment, the auxiliary tube mother of selection is cast aluminium Si-Mg alloy pipe mother.In pipe bus after welding, flexible circuit conductor forms a conductive loop.In order to ensure that this pipe mother connects the welding quality of gold utensil, by the detection device of following current converter station tubular bus bar connection gold utensil, this pipe mother is connected the welding quality of flexible circuit conductor in gold utensil and detect.
As depicted in figs. 1 and 2, this detection device includes low-tension current source and at least two current sensor, and the pipe mother after two outfans of current source utilize alligator clamp to be connected to welding connects on gold utensil and auxiliary tube mother, is used for exporting electric current in flexible circuit conductor.Being respectively mounted current sensor on each bar flexible circuit conductor after welding, after switch, circulate the flexible circuit conductor after gathering welding the current value in flexible circuit conductor.
The low-tension current source that the present embodiment is selected is high-current dc power supply, high-current dc power supply generator incoming transport electricity AC380V.As other embodiments, it is also possible to the power source generator of the DC source selecting input current to be 220V, the most now access the power supply of 220V.
High-precision current table it is also associated with, for detecting the size of current that current source is exported on current source.
This detection device also includes the data processing unit for processing current sensor output, and this data processing unit is connected to the signal output part of current sensor.Data processing unit in the present embodiment is computer, and the usb data analog input card in computer accepts the data that current sensor sends, and by software program in computer, the data that this current sensor gathers is processed and analyzed.
