Embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As depicted in figs. 1 and 2, the calorimeter of the charged supply stabilizer of the present invention, bucket 10 in it comprises, outer bucket 7, power supply unit 20, water circulation mechanism and the bung 11 that is arranged at interior bucket 10 and outer barrel 7 tops, in bucket 10 place in the outer bucket 7 and between interior bucket 10 and outer barrel 7, be provided with air blanketing 8, bung 11 and outer 7 interior connections of bucket, water circulation mechanism comprises water intaking valve 3, ebullator 4, circulating valve 5, temperature regulating device 6 and water drain valve 17, water intaking valve 3 links to each other with bung 11 by pipeline, pipeline between water intaking valve 3 and the bung 11 is provided with ebullator 4, circulating valve 5 and temperature regulating device 6, water drain valve 17 links to each other with outer bucket 7 by pipeline, power supply unit 20 comprises switching power supply 1 and the inverter unit 2 that links to each other with extraneous power supply, switching power supply 1 is by inverter unit 2 and water intaking valve 3, ebullator 4, circulating valve 5 and water drain valve 17 link to each other. and switching power supply 1 inserts the voltage of civil power 220V, through behind the inverter unit 2, be converted into stable alternating current. be provided with rabbling mechanism in the interior bucket 10, this rabbling mechanism links to each other with switching power supply 1 by inverter unit 2. in the present embodiment, the rabbling mechanism that adopts spray to stir, this rabbling mechanism comprises stirring spray column 15 and stirs pump 18, stirring spray column 15 is installed in the interior bucket 10, stirring spray column 15 links to each other with outer barrel 7 outer stirring pump 18. and this stirring spray column 15 internally carries out spray in the bucket 10 by the drive of stirring pump 18, internally the aqueous medium in the bucket 10 produces the effect of stirring, guaranteed in the interior bucket 10 that water temperature everywhere is consistent substantially, can not appear at the different phenomenon of water temperature on the different water levels, thereby improved the measuring accuracy of calorimeter, can obtain more accurate measured value. bucket temperature probe 9 in being provided with in the interior bucket 10, be provided with outer bucket temperature probe 14 in the outer bucket 7, interior bucket temperature probe 9 links to each other with a low voltage unit 16 with an outer bucket temperature probe 14, low voltage unit 16 links to each other with inverter unit 2 by second switch power supply unit 19, can monitor the temperature of working environment by interior bucket temperature probe 9 and outer bucket temperature probe 14, and then make corresponding adjustment. be provided with hermetically sealed layer 12 between outer bucket 7 and the bung 11, be provided with semitight layer 13 between air blanketing 8 and the bung 11, thereby guaranteed the stable of this calorimeter working environment, bucket 10 is relative constant with the operating ambient temperature in the outer bucket 7 in also making, and has therefore improved the measuring accuracy of calorimeter.
Referring to shown in Figure 4, in the prior art, operating voltage and frequency fluctuation change greatly during energising, are subjected to external influence bigger, thereby the stirring to the temperature rise collection of calorimeter, interior bucket 10 all can bring very big influence (under the different situations, the difference of the curve of Y1 and Y2 is very big).At first, the change of frequency, instability, can influence the consistance of rabbling mechanism stirring rate, the moment that produces is just unstable, and then bucket 10 stirring efficiency in having influence on, promptly influence the speed of transmitting heat in the inside bucket of oxygen bomb 10 water, interior bucket 10 temperature that measure are difficult to reflect the real temperature variation of oxygen bomb in the test, thereby have influence on the accuracy of measurement result.Equally also can give interior bucket 10 temperature variation because of the instability of the inconsistent heat of stirring that brings of stirring efficiency in addition and bring some uncertain factors, finally the stability of test result be brought influence.Moreover, spread of voltage, have and disturb or clutter, the collection of bucket 10 temperature rises in can influencing.Temperature is a weak signal, interference can not be arranged, and provide the civil power of power supply itself just unstable to amplifying unit, this will make through the temperature signal clutter after amplifying too many, directly have influence on the accuracy of adopting the temperature value, promptly can not get truly, accurately in bucket 10 experiment temperature rises, thereby influence measurement result.In addition, spread of voltage, have and disturb and clutter also can have influence on the acquisition precision of outer bucket 7 temperature, and adopt the prerequisite that temperature is a temperature control, it is not high naturally to adopt the inaccurate temperature-controlled precision of temperature, and a stable test environment also just can't be provided, final influence or experimental result.Therefore unsettled 220V alternating current must be handled, through switching power supply 1 it be become stable 12V direct current earlier, for inverter unit 2 provides operating voltage.Inverter unit 2 is handled direct current 12V and is produced stable 220V alternating current output through inversion module.Referring to the schematic diagram of Fig. 3 inverter unit 2, the DC12V input, through the pwm control signal of IC1 generation 50Hz, the pwm signal control metal-oxide-semiconductor IRF540 of two-way complementation and the elementary composition of transformer X2 are recommended output, and filtering promptly obtained stable 220V power supply after X2 boosted.Frequency and magnitude of voltage all are stable (waveform can keep for a long time referring to shown in Figure 5) after treatment, and it is consistent therefore providing the stirring efficiency of the stirring pump 18 of working power by it, and the heat of stirring of generation is stable; Simultaneously through adopting the clean effectively no clutter of warm signal after amplifying.In addition, interchange become the Switching Power Supply of direct current, therefore also just make all pumps, valve and Cai Wen unit wider, can reach 220V ± 20% accommodation of voltage because before inverter, must add one.
By long-term test as can be known, the calorimeter of the charged supply stabilizer of the present invention obviously is being better than common calorimeter aspect measuring accuracy, stability, the adaptability, the battery of tests data of following table 1 for extracting are by powering up supply stabilizer and the more provable above-mentioned theory of data that does not power up supply stabilizer in the table.
