Description
Technical field
The present invention relates to the using method of the load power source of negative resistance charactertistic change, the load power source especially relating to the change of a kind of negative resistance charactertistic realizes the using method of the pilot circuit of multi-functional.
Background technology
The demand of polysilicon mainly comes from semi-conductor and solar cell.Different by purity requirement, be divided into electronic-grade and solar level.Can find out that its development trend is silicon single crystal, polysilicon, banded silicon, thin-film material (comprising microcrystalline silicon film, compound base film and dye film) from the evolution of current international solar cell.Polysilicon is the direct material of manufacture order crystal silicon, is the electronics and information infrastructure material of the semiconducter device such as contemporary artificial intelligence, automatically control, information processing, opto-electronic conversion.Be called as " foundation stone of Microelectronics Building ".The production technology of polysilicon is mainly improved Siemens and silane thermal decomposition process.Siemens Method produces column of polysilicon by the mode of vapour deposition, and industrial silicon is processed into SiHCI by this technique, then allows SiHCl3 in the reduction furnace of H2 atmosphere, reduce deposition to obtain polysilicon.Tail gas H2, SiHCl3 that reduction furnace is discharged and HCl recycling after being separated.The reaction vessel (reduction furnace) of polysilicon, for what seal, uses electrically heated silicon rod, growing polycrystalline silicon on the rod of 1050 ~ 1100 degree.Reduction furnace and heating silicon rod power supply are very important technical equipment in polysilicon production process, and it completes the production technique link from trichlorosilane to polysilicon.
At the polycrystalline reduction initial stage, silicon rod diameter is less, and resistance value is comparatively large, and require to provide very high voltage just can puncture silicon rod group in reaction vessel, generation current on rod, just can reach the object of heating.Along with the growth of silicon rod, its diameter increases gradually, and resistance reduces gradually, and voltage reduces electric current and increases.In reduction production process, because silicon rod resistance change is very large, electric current and voltage variation range is wide especially, using voltage range, improving plant factor, have employed power unit parallel-series technology for reducing.In operation in earlier stage, voltage request is high, power unit series connection access, automatically switches to power unit parallel connection access after silicon rod producing electric current to a certain degree.
In addition, in the process of reduction growth, there is very large change in silicon rod resistivity, and demand power is large, voltage, curent change wide ranges.For these problems, have employed the many taps of transformer at present, multilevel voltage switches control, and power unit lamination controls and load parallel-series controls to combine.
Mostly adopt AC voltage adjusting scheme in current technique, and whole equipment dividing high voltage startup system, having formed every cutting cabinet, main transformer switch cabinet and reduction transformer, reduction power supply system.
High voltage startup part: the adjustable voltage of high voltage startup power source supplies AC 0 to 12KV, and every platform high voltage start cabinet provides power supply (each ∏ type silicon core, we represent with R) for a ∏ type silicon core.In Fig. 1,4 high voltage startup power supplys can only give 4 ∏ type silicon core heating simultaneously, if there be N number of ∏ type silicon core (N≤4) in stove, whole silicon core is started we to need to run high voltage startup system N/4 time, (after this high voltage startup system device stops just entering formal production status, reuse when next time opens stove, which decrease the rate of utilization of equipment).This mode such as needs reduce the number of starts, save and open the stove time, need increase high voltage startup number of power sources to reduce the number of starts, just can achieve the goal.
Reduction part: reduction power section mostly adopts Alternating Current Power Supply at present.To Alternating Current Power Supply wide ranges, general voltage is 300V-3000V; Electric current is between 30-3000A.
The scheme that current maturation is run as shown in Figure 1, all adopts reduction power section and high voltage startup part two portions composition.
Some deficiency following is there is for main in existing scheme:
1, need to provide high voltage startup power unit more, cause power supply system complexity, too fat to move, huge, waste, practicality is restricted (high voltage startup equipment only uses when opening stove, other time shut down stand-by).
2, high voltage startup power supply provides 0-12KV power supply, and this high voltage electric is to transmission route, and the devices such as equipment have very high insulating requirements.All require to select specific insulating products on circuit or on load device.
3, multiple stage reduction furnace shares a set of high voltage startup system, and when wherein a reduction furnace is when using high voltage startup system, other reduction furnaces must be waited for, after this stove has started, just start sequential reduction stove.Therefore, the production time has been had a strong impact on.
4, high voltage start cabinet increasing number, can not realize the saving of material, floor space, large by place limiting factor.
5, reduction power supply provides 300V-3000V, 0-3000A power supply, and its regulation range is wide, control difficulty large, and equipment need select device restricted.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency existing in prior art, provide a kind of using method of load power source, to realize following goal of the invention:
1, same equipment can realize starting, reducing dual-use function.
2, series, parallel operation function can be realized to power unit; Series, parallel pattern can be realized to load.
3, lower trigger voltage.
4, not for difference of dividing into groups increases equipment.
5, every all each own starting outfit of cover system.
6, power supply is direct current.
As power supply can realize the function of reduction part, the function (reduction part and high voltage startup part are integrated) of high voltage startup part can be realized again simultaneously, and the parallel-series control of power supply, load can be realized, the equipment such as high voltage startup power supply and isolating switch cabinet will be saved and reduce device element, and optimizing the requirement of reduction power supply.Thus optimize whole system function, reduce the complicacy of system, and then the technical problem proposed can be solved above.
In order to realize foregoing invention object, the invention provides following technical scheme:

Various switches in system can be isolation switch, contactor, vacuum contactor, isolating switch, vacuum interrupter, and also can be any all devices that can realize congenerous, label K*/K**/* K* of switch only does mark action in systems in which.
In described reduction step mid-term, be set to tandem working mode between described reduction power supply cabinet, between described load, be set to mode of operation in parallel;
Along with the growth of silicon core load, required voltage reduces, and therefore when certain condition, realizes power sources in series, load in series operating mode.
In the described reduction step later stage, be set to parallel running mode between described reduction power supply cabinet, between described load, be set to tandem working mode.
At silicon core load Later growth, required voltage reduces, and electric current is large, therefore when certain condition, realizes power sources in parallel, load in series operating mode.
Therefore, in the change of load through 2 mode of connection, power supply, through the change of the power supply mode of 3 times, completes the process of growth of whole silicon core.
The method also comprises the steps:, before described setting up procedure, to heat reduction furnace.
Before being initiated, we first adopt the mode of indirect heating, and whole in-furnace temperature is elevated to a certain degree.And then carry out start-up course.
Due to heating temperatures degree disunity in reduction furnace, according to characteristics such as the resistivity of load, temperature is higher lower to the trigger voltage needed for polysilicon load.Therefore, we need to be controlled reduction power cabinet by practical situation in the design process.
Described reduction power supply cabinet adopts pulse wave rectifier direct supply.

This scheme is adopted to have following advantage:
1, power unit can carry out series and parallel control, realizes improving output voltage and increasing outward current;
2, control simply, reliably to improve and control current/voltage precision;
3, reduce main-transformer tap, reduce transformer and equipment cost, make the more economical practicality of system;
4, low harmony wave, the advantages such as high-level efficiency.

In Fig. 2,12 reduction power supply cabinets are represented with code name A1-1, A1-2, A2-1, A2-2, B1-1, B1-2, B2-1, B2-2, C1-1, C1-2, C2-1, C2-2 respectively; And using B2-1, B2-2, C2-1, C2-2 tetra-reduction power supply cabinets as startup power cabinet.As shown in Figure 2, workflow is as follows for its skeleton diagram:
1, when system selectes 4 pairs of loads that will start corresponding to the second reduction power supply cabinet A1-2 (4 pairs of loads corresponding to A1-2 reduction power supply cabinet are called for short: the second reduction power supply cabinet A1-2 phase load), second dispense switch K2 closes a floodgate, start first subsequently, second source facility switching K11, K12 closes a floodgate, be that path has been reached in the 4 pairs of loads startups of the second reduction power supply cabinet A1-2 phase, for the reduction power supply cabinet B2-1 of described setting up procedure, B2-2, C2-1, C2-2 output voltage, voltage is by first, second source facility switching K11, K12, second dispense switch K2 reaches often pair of load two ends, wait load punctures, and when reaching conditions suitable, cut off the reduction power supply cabinet B2-1 for described setting up procedure, B2-2, C2-1, C2-2, disconnect first, second source facility switching K11, K12, second dispense switch K2, then close a floodgate reduction power supply isolator 1K2, 1K3, second reduction power supply cabinet A1-2 starts working.Now the second reduction power supply cabinet A1-2 phase load enters reduced state, and namely the second reduction power supply cabinet A1-2 is in reduction power supply state.
2, after the second reduction power supply cabinet A1-2 has started, when system is selected and will be started 4 pairs of loads corresponding to the first reduction power supply cabinet A1-1 (4 pairs of loads that the first reduction power supply cabinet A1-1 is corresponding are called for short: the first reduction power supply cabinet A1-1 phase load), first dispense switch K1 closes a floodgate, start first, second power unit K switch 11 subsequently, K12 closes a floodgate, and is that path has been reached in the first reduction power supply cabinet A1-1 phase load startup.For reduction power supply cabinet B2-1, B2-2, C2-1, C2-2 output voltage of described setting up procedure, voltage reaches often pair of load two ends by first, second power unit K switch 11, K12, the first dispense switch K1.Wait load punctures, and when reaching conditions suitable, cuts off reduction power supply cabinet B2-1, B2-2, C2-1, the C2-2 for described setting up procedure, disconnect first, second power unit K switch 11, K12, the first dispense switch K1.Then close a floodgate reduction power supply isolator 1K1, and the first reduction power supply cabinet A1-1 starts the work of reducing.
3, after the first reduction power supply cabinet A1-1 phase load and the second reduction power supply cabinet A1-2 phase load have started, every platform reduction power supply cabinet can simultaneously for the ∏ type silicon core of two series connection provides high voltage startup to power, when then system is selected and will be started remaining phase load, 4th dispense switch K4 closes a floodgate, starting first, second power unit K switch 11 subsequently, K12 closes a floodgate, is that path has been reached in the startup of the 5th, the 6th reduction power supply cabinet B1-1, B1-2 phase load.For the reduction power supply cabinet B2-1 of described setting up procedure, B2-2, C2-1, C2-2, output voltage, voltage reaches each 2R load two ends by first, second power unit K switch 11, K12, the 4th dispense switch K4.Wait load punctures, and reach conditions suitable, cut off reduction power supply cabinet B2-1, B2-2, C2-1, the C2-2 for described setting up procedure, off voltage is by first, second power unit K switch 11, K12,4th dispense switch K4, then close a floodgate reduction power supply isolator 3K1,3K2,3K3, and the 5th, the 6th reduction power supply cabinet B1-1, B1-2 starts the work of reducing.
4, when system selectes reduction power supply cabinet C1-1, C1-2 phase load that will start for described setting up procedure, 5th dispense switch K5 closes a floodgate, starting first, second power supply subsequently and offer standby pass K11, K12 combined floodgate, having reached path for starting for reduction power supply cabinet C1-1, C1-2 phase load of described setting up procedure.For the reduction power supply cabinet B2-1 of described setting up procedure, B2-2, C2-1, C2-2, output voltage, voltage reaches each 2R load two ends by first, second power switch K11, K12, the 5th dispense switch K5.Wait load punctures, and when reaching conditions suitable, cut off reduction power supply cabinet B2-1, B2-2, C2-1, the C2-2 for described setting up procedure, disconnect first, second power switch K11, K12,5th dispense switch K5, then close a floodgate reduction power supply isolator 4K1,4K2,4K3, and reduction power supply cabinet C1-1, C1-2 for described setting up procedure start the work of reducing.
In like manner, the principle of work for the 3rd, the 4th, the 9th, the tenth power supply reduction cabinet A2-1, A2-2, B2-1, B2-2 is consistent with aforesaid way.
5, when last two other reduction power supply cabinet C2-1, C2-2 phase load for described setting up procedure remaining is not activated, directly reduction power supply isolator 6K1,6K2,6K3 can be closed a floodgate, carry out puncturing startup.Reduction power supply cabinet C2-1, C2-2 for described setting up procedure directly enter reduction working order.
Two, restoring function:
Caused by load characteristic, the voltage needed for growth load in early stage is higher, and each reduction power supply cabinet is only to 2 2R load supplyings.Later stage load required voltage is more and more less, therefore can by 4 direct tandem workings of 2R load in the later stage.Current-voltage correlation needed for load, power cabinet can be carried out series-parallel system provides power supply.As shown in Figure 3:
1, in load reduction in earlier stage, because required voltage is higher, therefore reduction power supply isolator 1K1,1K2,1K3 closes a floodgate, and realizes each reduction power supply cabinet and powers to 2 of its correspondence 2R loads.To meet early growth requirement, load is parallel operation, as shown in the operating mode 1 in Fig. 3.
2, along with the growth of silicon core load, required voltage reduces, therefore when the voltage sum in 4 2R loads is less than the maximum output voltage sum of 2 reduction power supply cabinets, disconnect reduction power supply isolator 1K1,1K2,1K3, combined floodgate 1K1,1K3,1K6 realize power sources in series, load in series operating mode, as shown in the operating mode 2 in Fig. 3.
3, at silicon core load Later growth, required voltage reduces, electric current is large, therefore when the voltage sum in 4 2R loads is less than the maximum output voltage of 1 reduction power supply cabinet, disconnect reduction power supply isolator 1K1,1K3,1K6, combined floodgate 1K1,1K3,1K4,1K5 realize power sources in parallel, load in series operating mode, as shown in the operating mode 3 in Fig. 3.
4, therefore, in the change of load through 2 mode of connection, power supply, through the change of the power supply mode of 2 times, completes the process of growth of whole silicon core.
In reduction production process, because load characteristic changes greatly, higher to power requirement in whole process of growth, and to the voltage that power supply provides, current requirements is also higher.To this, we propose to realize series, parallel operation function to power unit; Series, parallel pattern is realized to meet production of polysilicon requirement to load.Its schematic circuit is as shown in Figure 4:
This power supply system is powered by 12 power cabinets.We select arbitrarily two of a phase reduction power supply cabinets to realizing power unit series, parallel operation function; Load realizes the explanation (such as: select the first reduction power supply cabinet A1-1, the second reduction power supply cabinet A1-2 two reduction cabinet is example) of the dual-use function of series, parallel pattern.
Due to need of production in early stage, to first, second reduction power supply cabinet A1-1, A1-2 respectively to the load supplying corresponding to it, achieve the parallel running of load.As in Fig. 5, reduction power supply isolator 1K1,1K2,1K3 close a floodgate, the first reduction power supply cabinet A1-1 powers to front 4 R in load, and the second reduction power supply cabinet A1-2 powers to rear 4 R in load.Its sense of current as shown in Figure 5.
Because pull-up resistor constantly changes in process of production, in order to improve power supply rate of utilization and meet need of production.In load 8 R need be connected, first, second reduction power supply cabinet A1-1, A1-2 give 8 series connection R load supplyings again after need connecting.As in Fig. 6, reduction power supply isolator 1K6 closes a floodgate, first, second reduction power supply cabinet A1-1, A1-2 carries out series connection and reaches raising voltage; Close a floodgate reduction power supply isolator 1K1,1K3 again, and first, second reduction power supply cabinet is 8 series connection R load supplyings by reduction power supply isolator 1K1,1K3.Its sense of current as shown in Figure 6.
In order to meet the requirement of load phase needs low voltage, big current after manufacture.First, second power cabinet A1-1, A1-2 need carry out after parallel connection again to 8 series connection R load supplyings.As reduction power supply isolator 1K1,1K4 in Fig. 7; 1K3,1K5 close a floodgate, and first, second power cabinet A1-1, A1-2 carry out parallel connection and reach that to increase outward current be 8 series connection R load supplyings.Its sense of current as shown in Figure 7.
Before being initiated, we first adopt the mode of indirect heating, and whole in-furnace temperature is elevated to a certain degree.And then carry out start-up course.
Due to heating temperatures degree disunity in reduction furnace, according to characteristics such as the resistivity of load, temperature is higher lower to the trigger voltage needed for polysilicon load.Therefore, we need to be controlled reduction power cabinet by practical situation in the design process.
Scheme and reduction scheme are started to this kind, enough production requirement is met at below 3.6KV to the design of reduction power supply cabinet.Its advantage is as follows: due to voltage range reduce to 3.6KV grade by 10KV grade or lower after, the insulating requirements of electrode in stove is reduced greatly, load number can be arranged more, increase production output.To the requirement also corresponding reduction of reduction power supply cabinet design.All electrical element requirements of type selecting are reduced.In transmitting procedure, line requirements is also lowered the requirement greatly.
In addition, in reduction furnace, polycrystalline silicon core load logarithm is different, and we can be divided into some groups, and often group quantity is determined according to different situations.This startup scheme is practically applicable to all grouping schemes.Power unit can't be increased because grouping is different.This programme is more practically applicable in complicated and diversified polycrystalline silicon reducing furnace.
The startup scheme of concrete different grouping is lifted following example and is illustrated:
As shown in Figure 8:
1., N, the load of silicon core is made up of (N≤2) in reduction furnace;
2., each reduction power supply cabinet for M to the load of silicon core provide reduction power supply (1≤M≤N);
3., each reduction power supply cabinet starts power supply (1≤R≤N) for load R provides;
4., according to the grouping of load, can determine to need X platform reduction power supply cabinet (X≤2);
5., in a reduction power supply system, Y platform reduction power supply cabinet can be had as startup power cabinet (Y≤X-1).
Therefore, in pipe furnace, the load of silicon core does not have how many, and we can find the array mode matched with it, and can divide different groups in same reduction furnace, and each load number started can not be identical.This kind of scheme can realize the diversity of reduction furnace internal burden.Improve the practicality of whole system.
In actual applications, a set of reduction power supply cabinet joined by every platform reduction furnace.Then often overlapping restoring system all uses own reduction power supply cabinet as the startup power cabinet of oneself.
Reduction power supply adopts pulse wave rectifier direct supply to realize whole power unit function.This scheme is adopted to have following advantage:
1., power unit can carry out series and parallel control, realization raising output voltage and increase outward current;
2., control simply, reliably improve and control current/voltage precision;
3., reduce main-transformer tap, reduce transformer and equipment cost, make the more economical practicality of system;
4., low harmony wave, the advantages such as high-level efficiency.
