The work of above-mentioned generator main body now is described.Use the kick starter that is connected with engine to start as the drive source of generator main body.In case the pulling kick starter then makes the rotor rotation that links with the bent axle of engine, ancillary coil L5 produces voltage, and by means of this voltage, constant voltage circuit 22 forms the voltage of stipulating.In case apply this voltage, the control of controller 16 can begin.
Utilize kick starter one to make engine rotation, in the engine just by above-mentioned ignition device and starter-generator.Coil L1～the L4 of generator main body and L5 begin generating respectively, and the electric power that is sent is merged, and export as generation power from lead-out terminal 10,11.This electric power is supplied to battery 19 and UPS20.
When the output generation power, output display lamp 26 is energized.In addition, when forming overcurrent or overvoltage, overload display lamp 27 is energized.And then, be reduced to fiducial value when following at the oil that is judged as engine with the method known, oily warning circuit 29 work, oily alarm display lamp 28 is energized.For example, oily warning circuit 29 is to be used to make electric current flow through oily alarm display lamp 28 and the switching circuit of formation from the signal of terminal LS.And then when oil reduces, or electricity generation system described later is when unusual, in the inside of controller 16 with terminal LS and terminal G short circuit, thereby controller 16 stops igniting.
In the present embodiment, to merge be that overlapping back is as final output in the output that so will comprise 4 Power Generation Sections (power subsystem) of coil and rectification circuit.And, following control unit is equipped with, make and be convenient to the battery 19 of different voltage specifications is charged by means of this output.
Fig. 3 is the block diagram of function of the controller 16 of the expression output usefulness of supplying with the voltage specification be suitable for battery.Owing to control three phase rectifier bridge-type circuit 2～5 simultaneously, thus below for representative its function is described with three phase rectifier bridge-type circuit 2.Preestablish three phase rectifier bridge-type circuit 2 output voltage V d1 desired value Vref and be stored in the desired value configuration part 33.Conversion according to voltage changeover switch～25 comes conversion target value Vref., enumerate a certain example that to select in 36 volts and 48 volts herein, but be not limited to this 2 yuan of settings.
The strobe pulse of the thyristor of output-controlling device 34 output control three phase rectifier bridge-type circuit 2 makes the output voltage V d1 of three phase rectifier bridge-type circuit 2 consistent with the desired value Vref of 33 supplies from the desired value configuration part.
When load judegment part 35 is transformed into the position of indication output beginning at key switch (main switch) 36, and load voltage VL supplies with output to output-controlling device 34 and allows signals when being in the predetermined scope that comprises voltage-target Vref.
When the result who differentiates load voltage VL at load judegment part 35 represented that load voltage VL is in the preset range that comprises desired value Vref, three phase rectifier bridge-type circuit 2 allowed to begin output, and when not in predetermined scope, then forbade output.And then, the differentiation result who makes in the load judegment part 35 can be set be easy to device into operating personnel identification.
Fig. 4 is the figure that the example of the demonstration that the differentiation result by load judegment part 35 obtains is shown.In the figure, the abnormal show lamp also can be the demonstration special lamp that the result is differentiated in this load, but in order not increase the number of display lamp, for example, preferably also can utilize above-mentioned overload display lamp 27.Below, the abnormal show lamp describes with overload display lamp 27.
Be under 36 volts the situation, to that is to say when diverter switch 25 is transformed into 36 volts of sides at desired value Vref, show below.Be lower than at load voltage VL under 27 volts the situation, the output of three phase rectifier bridge-type circuit 2 is under an embargo, and output display lamp 26 and overload display lamp 27 extinguish together.In addition, load voltage VL be in 27 volts～when being lower than in 42 volts the scope, the output of three phase rectifier bridge-type circuit 2 is allowed to.At this moment, output display lamp 26 is lighted, and overload display lamp 27 still keeps extinguishing.And then when load voltage VL was in 42 volts～55 volts scope, the output of three phase rectifier bridge-type circuit 2 was under an embargo.At this moment, output display lamp 26 extinguishes, and 27 flickers of overload display lamp are to give a warning.
On the other hand, desired value Vref is 48 volts a situation, that is to say showing below when diverter switch 25 is transformed into 48 volts of sides.Be lower than at load voltage VL under 27 volts the situation, the output of three phase rectifier bridge-type circuit 2 is under an embargo, and output display lamp 26 and overload display lamp 27 extinguish together.In addition, load voltage VL be in 27 volts～when being lower than in 42 volts the scope, the output of three phase rectifier bridge-type circuit 2 also is under an embargo.And output display lamp 26 extinguishes, and 27 flickers of overload display lamp are to give a warning.And then when load voltage VL was in 42 volts～55 volts scope, the output of three phase rectifier bridge-type circuit 2 was allowed to.And output display lamp 26 is lighted, and overload display lamp 27 extinguishes.
Have, not under the situation in any one scope of above-mentioned voltage, output display lamp 26 still keeps extinguishing on the location independent ground of load voltage VL and diverter switch 25 again, and overload display lamp 27 glimmers to give a warning.
Fig. 5 is the block diagram of function of the controller 16 of expression the 2nd embodiment, the function that the symbolic representation identical with Fig. 3 is identical or equal.
Force output judegment part 38 to determine pressure output that load voltage VL is in regulation when allowing in the voltage range, monitor the Continuity signal 16j that forces output switch 37 at load judegment part 35.Then, according to this Continuity signal 16j, during operation when judge forcing output switch 37 to be carried out to make it to force to export, supply with output to output-controlling device 34 and allow signals.
Fig. 6 is the flow chart of the processing of the load judegment part 35 among expression the 2nd embodiment, and Fig. 7 is the figure of this result of expression.In Fig. 6, in step S1, judge whether conducting of key switch 36, if key switch 36 conductings then proceed to step S2.Whether the desired value Vref that differentiates output voltage in step S2 is 36 volts.If desired value Vref is 36 volts, then proceed to step S3.Not under 36 volts the situation at desired value Vref, that is to say if 48 volts of another target setting values then proceed to step S15.
Whether in step S3, differentiate load voltage VL more than or equal to 2 volts (the 1st magnitudes of voltage).If load voltage VL is not more than or equal to 2 volts, then being judged as battery 19 is not connected, perhaps battery 19 extinguishes output display lamp 26 and overload display lamp 27 for overdischarge etc., the state that is not suitable for charging, forbids generating output (step S4, step S5 and step S6).Result going up most shown in lattice when load voltage VL is lower than the low-voltage that sets as the 1st magnitude of voltage as Fig. 7.Have, in order not increase the number of display lamp, permissible load factor display lamp 27 is realized the function of abnormal show lamp again, shows load differentiation result but also can be exclusively used in.
If load voltage VL is more than or equal to 2 volts, then proceed to step S7, judge that whether load voltage VL is more than or equal to 27 volts (the 2nd magnitudes of voltage).If load voltage VL is more than or equal to 27 volts, then proceed to step S8, judge that whether load voltage VL is more than or equal to 42 volts (the 3rd magnitudes of voltage).If load voltage VL is more than or equal to 42 volts, then be decided to be unusually, proceed to step S9, will export display lamp 26 and be maintained and extinguish, in step S10, make overload display lamp 27 be in blink states to give a warning, proceed to step S6, forbid that generating exports.Load voltage VL is result the descending most shown in the lattice as Fig. 7 during more than or equal to the 3rd magnitude of voltage.
Is the situation of step S8 for negating certainly at step S7, that is to say load voltage VL for more than or equal to 27 volts but be not more than under the situation that equals 42 volts, being judged as and being connected with the load corresponding with the output of Blast Furnace Top Gas Recovery Turbine Unit (TRT) is battery 19.Therefore, proceed to step S11, light output display lamp 26, overload display lamp 27 is extinguished, and then in step S13, allow generating output.Result when load voltage VL is between the 2nd magnitude of voltage and the 3rd magnitude of voltage is shown in the 3rd lattice of Fig. 7.
At step S7 for negating, that is to say load voltage VL for more than or equal to 2 volts, be lower than under 27 volts the situation, proceed to step S14, force to export processing.From load voltage VL, even this processing is to judge that battery 19 not necessarily is in the state that is suitable for charging most, promptly discharge capacity big, when big state falls in terminal voltage, the processing that also forcibly allow Blast Furnace Top Gas Recovery Turbine Unit (TRT) output, can charge.The situation of could exporting when moving to pressure output processing and the state of display lamp 26,27 are shown in the 2nd lattice of Fig. 7.
Now will force output to be handled and do a summary.Under the situation of the output that glimmer at overload display lamp 27, this overload display lamp 27 forcibly obtains Blast Furnace Top Gas Recovery Turbine Unit (TRT) when being blink states, carry out following operation.At first, will force output switch 37 to continue to be pressed into the conducting side and surpass for the 1st time.In response to this operation, overload display lamp 27 extinguishes.Extinguish by this, operating personnel can discern load voltage VL and be more than or equal to the 2nd voltage, are lower than the 3rd voltage, and by forcing output function to allow Blast Furnace Top Gas Recovery Turbine Unit (TRT) output.That is to say that operating personnel can discern the state shown in the lattice that descends most that present situation is not Fig. 7 by the state variation of overload display lamp 27, but the state shown in the 2nd lattice.
Therefore, operating personnel temporarily will force output switch 37 to turn back to and turn-off side (this switch 37 turn-offs side owing to be instantaneous type if loose one's grip then automatically to reset to).Then,, will force output switch 37 to be pressed into the conducting side again,, keep this conducting state always until through the 3rd time until through the 2nd time.By above switching manipulation, output display lamp 26 is lighted, and allows Blast Furnace Top Gas Recovery Turbine Unit (TRT) output.
Fig. 8 is the flow chart that recapitulative pressure output is handled.In step S141, output display lamp 26 is extinguished, in step S142, make 27 flickers of overload display lamp.In step S143, judge and force whether output switch 37 is conducting.If forcing output switch 37 is not conducting, then withdraw from this processing, turn back to the step S1 of Fig. 6.If forcing output switch 37 is conductings, then proceed to step S144, timer T1 is started.The timing value of timer T1 is above-mentioned the 1st time, for example is 5 seconds.
In step S145, judged whether to pass through the time T of measuring with timer T1 1.Being judged as under the situation of having passed through time T 1, proceed to step S146, judge to force whether conducting of output switch 37.If step S146 is sure, then be judged as until elapsed time T1, push always and force output switch 37, in step S147, overload display lamp 27 is extinguished.
After having extinguished overload display lamp 27, in step S148, wait for and force output switch 37 to be transformed into shutoff (step S148 is for affirming), proceed to step S149, timer T2 is started.The timing value of timer T2 is above-mentioned the 2nd time, for example is 5 seconds.In step S150, judged whether to pass through the time T of measuring with timer T2 2.Until elapsed time T2, proceed to step S151, judge to force whether conducting of output switch 37.
If before time of advent T2, force output switch 37 to become conducting, then proceed to step S152, timer T3 is started.Timer T3 is above-mentioned the 3rd time, for example is 5 seconds.In step S153, judge whether to have passed through time T 3, if passed through time T 3, then in step S154, judge to force whether conducting of output switch 37.Force 37 conductings of output switch if in step S154, be judged as, then proceed to step S155, light output display lamp 26, in step S156, allow Blast Furnace Top Gas Recovery Turbine Unit (TRT) output.
Like this, according to present embodiment,,, also can forcibly allow Blast Furnace Top Gas Recovery Turbine Unit (TRT) output in optimum range even under the situation that the output voltage of load voltage VL and Blast Furnace Top Gas Recovery Turbine Unit (TRT) does not meet by the operation of stipulating as required.Have again, by to forcing output switch 37 to carry out 2 operations, be not limited to make and force output to become possibility as mentioned above, also can imagine the situation relevant with various operations.For example, can further increase number of operations, perhaps also variable 1 time operating time, i.e. the 1st time or the 3rd time.In a word, as long as setting operation number of times or time make operating personnel to send indication with the definite meaning, in other words, misoperation does not take place get final product.
At the step S2 of Fig. 6 negate, that is to say that desired value Vref is that the processing of the step S15 under 48 volts the situation is deformed into and carries out load voltage VL whether more than or equal to 42 volts judgement in step S7, in step S8, carry out load voltage VL whether more than or equal to 55 volts judgement.Like this, because except the flow chart of change Fig. 6, be that 36 volts the processing of situation (step S2 is sure situation) is identical with desired value Vref, the Therefore, omited flow chart, but, result only is described with reference to Fig. 9.
Be under 48 volts the situation, to that is to say when diverter switch 25 is transformed into 48 volts of sides as follows at the desired value Vref of Fig. 9.As going up most shown in the lattice of Fig. 9, be to be lower than under 2 volts the situation at load voltage VL, forbid output, output display lamp 26 and overload display lamp 27 extinguish together.In addition, shown in the 2nd lattice of Fig. 9, load voltage VL be in more than or equal to 2 volts, when being lower than 42 volts scope, Blast Furnace Top Gas Recovery Turbine Unit (TRT) output is that three phase rectifier bridge-type circuit 2 is output as and forces output function to allow.And output display lamp 26 extinguishes, and 27 flickers of overload display lamp are to give a warning.And then, as descending most shown in the lattice of Fig. 9, load voltage VL be in more than or equal to 42 volts, when being lower than 55 volts scope, allow 2 outputs of three phase rectifier bridge-type circuit.And output display lamp 26 is lighted, and overload display lamp 27 extinguishes.
Above-mentioned voltage range is set in view of following aspect.At first, battery 19 obtains desirable voltage by a plurality of batteries.For example, the series connection of 48 volts battery uses 4,36 volts battery series connection to use 3 unit cells.And, be lower than 10.5 volts as if considering that life-span, constituent parts battery preferably are not used to discharge into.Therefore, the minimum voltage with spendable 48 volts battery 19 is decided to be 42 volts (=10.5 volts * 4).And as 36 volts the battery 19 that this minimum voltage of 42 volts is applied to be made of 3 unit cells, then the voltage of each unit cells is 14 volts (=42 volts of ÷ 3).That is to say that under the situation of 36 volts batteries 19, if the supposition ceiling voltage is 42 volts, then the voltage of unit cells is 14 volts, can not substantially exceed the floating charge voltage range (13.6 volts) of UPS20.Therefore, be the load voltage VL that the battery 19 of 36 volts battery 19 and 48 volts is differentiated on the boundary with these 42 volts.
The ceiling voltage (55 volts) of the battery 19 of the minimum voltage of the voltage range of 36 volts battery 19 (27 volts) and 48 volts is set to respectively and undercharge does not take place and overcharges.
Voltage range can be the value relevant with said reference, but is not limited to this concrete numerical value.In a word, can set under the situation of output voltage, as long as the voltage matches that benchmark makes voltage that sets and the load that is connected is set by diverter switch.In addition, the warning under the situation of two voltage mismatches is not limited to the warning of being sent by display lamp, also can be prompting of being sent by buzzer or electronics synthetic video etc.
In the present embodiment, enumerating the mobile generating device that has been equipped with a plurality of power subsystems that are made of coil and the rectification circuit corresponding with coil is that example illustrates the present invention.But, the invention is not restricted to the number of power subsystem.In addition, synchronously control with single thyristor control signal and a plurality of rectification circuit, but be not limited thereto, also available independently thyristor control signal is controlled rectification circuit.
