The technical scheme of portable super capacitor electric discharge device is:
For a portable Quick discharger for pitch-controlled system super capacitor, comprise stainless steel casing, four pieces of discharge resistances, two radiator fans, D.C. voltmeter, an air switch and the heavy-duty connector be connected with pitch-controlled system; It is characterized in that:
In stainless steel casing, arrange casing internal partition, internal partition both sides install two pieces of discharge resistances respectively, and two discharge resistances of every side are connected in series, and the discharge resistance after the series connection of internal partition both sides is connected in parallel formation main discharge circuit;
Install D.C. voltmeter at stainless steel casing upper wall, shown D.C. voltmeter is attempted by main discharge circuit outlet;
In the upside of stainless steel casing antetheca, rear wall and relatively a radiator fan is installed, in the power end parallel connection access main discharge circuit of two radiator fans respectively in the middle part of both sides discharge resistance;
The port of export of main discharge circuit is connected with the super capacitor two ends in pitch-controlled system by air switch, heavy-duty connector successively.
The utility model also comprises following scheme further:
The downside of stainless steel casing antetheca, rear wall offers louvre, and stainless steel casing connects protective earthing.
Described discharge resistance adopts aluminum casing resistor.
Adopting aluminum casing resistor as discharge resistance, is heat energy release by the Conversion of Energy in super capacitor.Aluminum casing resistor weatherability, vibration resistance, fail safe be high, be applicable to severe industry control environment and the light volume of quality is little, and the overburden of resistance to short time.
When designing, the utility model considers that super capacitor short-time load ability is strong, the characteristic that continuous discharge ability is large, select aluminum-housed resistor as discharge device, and have employed the radiator fan auxiliary heat dissipation that ventilation quantity is large, rotating speed is high, make whole design and implimentation very easy, cost is low, safe and reliable, is easy to carry.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present utility model.
Fig. 2 is the utility model portable super capacitor electric discharge device structured flowchart.
Wherein, in accompanying drawing 1,2, the implication of Reference numeral is as follows: 1 is heavy-duty connector, and 2 is air switch, 3 is D.C. voltmeter, and 4,5,6,7 is discharge resistance, and 8,9 is radiator fan, 10 is casing internal partition, and 11 is stainless steel casing, and 12,13 is stainless steel casing louvre.
Embodiment
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
As shown in Figure 1, four pieces of discharge resistance type selectings are consistent.Wherein discharge resistance 4 and discharge resistance 5 are connected, and discharge resistance 6 and discharge resistance 7 are connected, then at the resistor coupled in parallel connected two groups.After in parallel, air switch 2 is accessed in one end (positive pole), for controlling the access of whole discharge loop and cutting out; The other end (negative pole) after parallel connection accesses the negative pole of heavy-duty connector 1.Radiator fan 8 and radiator fan 9 parallel connection, then between one end access discharge resistance 6 and discharge resistance 7, the other end also accesses heavy-duty connector negative pole.D.C. voltmeter 3 one end directly connects and heavy-duty connector positive terminal, and the other end is also be connected to heavy-duty connector negative pole.Have 3 wiring in heavy-duty connector, one connects super capacitor positive pole, and one connects super capacitor negative pole, and another root connects earth connection.Air switch 2 is connected and is accessed discharge loop, drops into and excision for controlling whole discharge loop.When heavy-duty connector and pitch-controlled system connect, after air switch 2 is closed, total load is about 4 ohm.For the super capacitor of 60V terminal voltage, its maximum discharge current is no more than 15 amperes, within the load current scope of super capacitor.
