summary of the invention:
the purpose of this utility model is to provide a kind of high power DC resistor load box.Adopt manual mode, the connected mode that only need change short-circuit piece just can realize the increase and decrease of load.
above-mentioned object is realized by following technical scheme:
a kind of high power DC resistor load box, its composition comprises: resistor load box, described resistor load box inside is provided with 6 high-power resistance silks, one group of short-circuit piece, 6 described high-power resistance silks are that four segmentation high-power resistance silks are from top to bottom equidistantly fixed in described resistor load box, and described 6 resistance wires connect for full parallel connection or entirely connect or connection in series-parallel by one group of described short-circuit piece respectively.
beneficial effect:
1. the utility model is high power DC resistor load box, adopts manual mode, and the connected mode that only need change short-circuit piece just can realize the increase and decrease of load.
2. the utility model can arrange the input patterns such as full parallel connection, full series connection or connection in series-parallel:
under full paralleling model, by short-circuit piece by all in parallel for 6 resistance wires, just can complete heavy duty and arrange, now load total resistance value is minimum, and the current value that load is flow through is maximum.
under full series model, all connected by 6 resistance wires by short-circuit piece, just can complete underload and arrange, now load total resistance value is maximum, and the current value that load is flow through is minimum.
under connection in series-parallel pattern, by short-circuit piece by 6 resistance wire part in parallel, then connect with all the other resistance wires, now can adjust load flexibly as required.Also can experimentally need a certain or a few in use 6 resistance wires load is set.
3. the direct current resistance load box internal heat dissipating element designed by the utility model adopts dry type resistance wire, and without cooling device, sectional type resistance can carry out connection in series-parallel according to load, and power density is high, and without red heat phenomenon, safe life is long.
4. the utility model complete machine adopts modular design, simple to operate, easy to maintenance, and the pick-up units such as configuring direct current voltage, reometer.
5. the utility model arranges AC and DC voltage, current sensor in resistor load box inside, and is placed in load box top by the mode of numerical monitor, facilitates experimenter to observe.
