The specific embodiment
The basic structure of the induction heater that at first, explanation is used in the overheated steam generating apparatus with reference to Fig. 2 and Fig. 3.Among Fig. 2; Unshakable in one's determination 1 constitutes closed magnetic circuit, and (following is called iron core; Expression is wound with the post core portion of coil among the figure); Primary winding 2 is wrapped on the iron core, and conductor tube 3 is by the SUS formations such as (stainless steels) that is wrapped on the iron core, and soldering weld part 4 mechanically connects fixed conductor pipe 3 and conductor tube 3 is electrically connected.Connect between the fixing adjacent conductor tube 3 and make between the adjacent conductor tube 3 through TIG electroplating equipment wielding machine ground and be electrically connected, conductor tube 3 becomes the secondary coil with a circle of the electrical short circuit of secondary coil.Under this structure; If in primary winding 2, apply alternating voltage; Then produce alternating flux in the iron core 1; With the conductor tube 3 of the secondary coil of this alternating flux interlinkage in produce induced-current, conductor tube 3 is because of this induced-current heat that has a resistance, the heating of said conductor tube 3 is used for water and the saturated steam in the heater pipe.
The overheated steam generating apparatus of said embodiment 1 is the conductor tube through two induction heaters that connect said structure, is made up of two induction heaters.At this, be called first induction heater to the induction heater that generates saturated steam from water, be called second induction heater to the induction heater that generates overheated steam from saturated steam.
Promptly; When generating saturated steam; In conductor tube 3, water is filled near the assigned position the flow export 3b (with reference to (b) of Fig. 3), and in primary winding 2, applies alternating voltage from the bottom inflow entrance 3a (with reference to (b) of Fig. 3) of the conductor tube 3 of first induction heater.In unshakable in one's determination 1, produce alternating flux through applying said alternating voltage; With the conductor tube 3 as secondary coil of this alternating flux interlinkage in produce induced-current; Conductor tube 3 through the water in this heat conductor tube 3, thereby generates saturated steam because of this induced-current heat that has a resistance.The saturated steam that generates is sent in the conductor tube 3 of second induction heater.
At this moment, owing to generate and emit saturated steam,, detect the water level in the conductor tube 3 of first induction heater through liquid level gauge etc., along with the reduction of water level is supplied water so the water levels in the conductor tube 3 of first induction heater reduce.In addition, detect the temperature of the water in the conductor tube 3 that is the temperature of saturated steam, and the electric current of primary winding 2 is flow through in control so that the temperature of the temperature of the water in the conductor tube 3 that is saturated steam becomes the temperature (for example 130 ℃) of regulation.The secondary coil of the coiled type that forms through coiled conductor pipe 3; Can obtain the total length of elongated conductor tube 3; It is big that heat transfer area becomes, and the temperature difference of the water that the temperature of conductor tube 3 is inner with it is little, and the temperature that detects conductor tube 3 just can detect the temperature of saturated steam.
When generating overheated steam, the saturated steam that will send here from first induction heater imports from the bottom inflow entrance 3a of second induction heater ((b) of Fig. 3 with reference to), and in primary winding 2, applies alternating voltage.Through applying said alternating voltage; Produce alternating flux in unshakable in one's determination 1; With the conductor tube 3 of the secondary coil of this alternating flux interlinkage in produce induced-current; Through this induced-current, conductor tube 3 heat that has a resistance, the saturated steam in the conductor tube 3 of heat second induction heater through this resistance heat.At this moment, also through detecting the temperature of conductor tube 3, and through the electric current that flows through in the primary winding 2 is controlled, make the temperature of the overheated steam in the conductor tube 3 become the temperature (for example 500 ℃) of regulation.
In addition; As shown in Figure 4, the conductor tube 3 of induction heater is configured between the primary winding 2, promptly twines primary winding 2 along unshakable in one's determination 1; And on the periphery of said primary winding 2; Along these primary winding 2 coiled conductor pipes 3, be electrically connected mechanically connecting fixing between the adjacent conductor tube 3 and making between the adjacent conductor tube 3, twine primary winding 2 along said conductor tube 3 again.If through disposing the secondary coil that is made up of said conductor tube 3 as described above, then the magnetic flux with this secondary coil interlinkage increases, thereby the electric current that in conductor tube 3, flows thus increase can improve the efficiency of heating surface.
But a large amount of electricity consumptions of shop equipment must be used three-phase alternating-current supply.Fig. 1 has represented the circuit of embodiment 1, and this circuit makes the electric current between the three-phase (U, V, W) of three-phase alternating-current supply not produce two induction heaters that big imbalance just can connect embodiment 1.Three-phase alternating-current supply 5 has been shown among Fig. 1, and three-phase voltage controller 6, T connect transformer 7, single-phase transformer 8 and single-phase voltage controller 9.
To connect the primary winding 2 of the teaser transformer of transformer 7 from the primary winding that water generates first induction heater of saturated steam as T, and the primary winding of second induction heater that will generate overheated steam from saturated steam is as the primary winding 2 of single-phase transformer.T connects three input terminals (U1, V1, W1) of transformer 7; Through three-phase voltage controller 6 respectively with three-phase alternating-current supply each mutually (U, V, W) connect; The input terminal of the primary winding 2 of single-phase transformer 8 (V2, W2), through single-phase voltage controller 9 respectively with the illustrated example of three-phase alternating-current supply in V be connected with W mutually.Through described connection, can control the electric current that flows through in the primary winding of the electric current that flows through in the primary winding of first induction heater and second induction heater respectively independently.
In addition; Teaser transformer is connected with main transformer T; If the number of turn between the V1-W1 of main transformer is N; Then the number of turn between V1-O (wire connecting portion) and the number of turn between W1-O be the number of turn between the U1-O of N/2 and teaser transformer for
as long as satisfy said condition; Teaser transformer and main transformer can be made up of single-phase transformer, and teaser transformer and main transformer also can be three-phase integrated types.Under the situation of three-phase integrated type, if area of section in the three post iron cores, that be wound with two newel posts of teaser transformer and main transformer coil is S, then the central rods area of section does
When obtaining 130 ℃ saturated steam through first induction heater, and when obtaining 500 ℃ overheated steam through second induction heater, both heat ratios are about 2: 1.When the induction heater of the first primary coil connected to the three-phase power UV, the induction heater and a second coil is connected when the VW, the current ratio of U: V: W = 1:1.323:0.5 , maximum current and minimum current ratio of 2.65 times, three phase currents have a huge imbalance, this connection will lead to substation equipment (powered device) tolerance.But; If the primary winding of first induction heater is connect the primary winding of the teaser transformer of transformer as T; Then said current ratio is U: V: W=1: 0.661: 0.661; The ratio of maximum current and minimum current is 1.51 times, can suppress said big imbalance, can also suppress the high capacity of converting equipment.
The overheated steam generating apparatus of this embodiment 2; Same with embodiment 1, also be conductor tube through the secondary coil that connects two induction heaters, constitute by two induction heaters; Primary winding as each induction heater also adopts conductor tube, and the water that in this conductor tube, circulates.With reference to Fig. 6 and Fig. 7 the induction heater that uses among this embodiment 2 is described.Illustrated among Fig. 6 by connecting the post unshakable in one's determination 11 that 11b unshakable in one's determination constitutes closed magnetic circuit; Be wrapped in the conductor tube that the is made of copper 12 (primary windings on the post iron core; Embodiment illustrated is that cross sectional shape is tetragonal conductor tube); Be wrapped in the conductor tube of processing by SUS etc. 13 (secondary coil, embodiment illustrated are that cross sectional shape is circular conductor tube) on the iron core, insulating paper 15 and solvent-free be insulating adhesive layer 16.

In above embodiment 1 and embodiment 2, used two induction heaters to constitute the overheated steam generating apparatus,, caused the complex structure of overheated steam generating apparatus so used T to connect transformer device structure and single-phase transformer structure, bothersome on making.Embodiment 3 makes the structure of overheated steam generating apparatus become more simple.In said embodiment 1 and embodiment 2, two induction heaters have been used; But embodiment 3 is divided into two with an induction heater that generates saturated steam in said two; Constitute the overheated steam generating apparatus with three induction heaters of total, and with a three-phase transformer structure that constitutes three posts (being wound with three iron cores of coil) after closed magnetic circuit (connecting unshakable in one's determination) the unshakable in one's determination generalization.Utilize aforesaid structure, in the primary winding that constitutes each induction heater, can apply the voltage between phases of three-phase alternating-current supply.
Below with reference to Fig. 8 and Figure 11, the three-phase transformer structure of the main body that constitutes the overheated steam generating apparatus is described.Top has been shown among Fig. 8 has connected 31a unshakable in one's determination; The bottom connects 31b unshakable in one's determination, circular post 32a unshakable in one's determination, 32b, 32c, leakage magnetic circuit unshakable in one's determination 33; Terminal plate 34; Be wrapped in the coil 35a on the circular post 32a unshakable in one's determination, be wrapped in the coil 35b on the circular post 32b unshakable in one's determination, be wrapped in coil 35c and insulation 36 on the circular post 32c unshakable in one's determination.Order according to post 32a unshakable in one's determination, leakage magnetic circuit iron core 33, post 32b unshakable in one's determination, leakage magnetic circuit iron core 33, post 32c unshakable in one's determination; The post 32a unshakable in one's determination, 32b, 32c and the leakage magnetic circuit unshakable in one's determination 33 that are wound with the circle of coil are (in this example; The area of section of leakage magnetic circuit unshakable in one's determination 33 is 1/2 of a post area of section unshakable in one's determination; Reason is seen after and is stated) respectively with predetermined distance configuration, fastened in the end clips up and down of described iron core that top connects 31a unshakable in one's determination, the bottom connects 31b unshakable in one's determination.In addition, preferably, circular post iron core forms by the thin silicon steel plate is range upon range of in a circumferential direction, the curvature portion that said thin silicon steel plate has bend shown in Figure 4 and is connected and bends to involute shape with this bend.In this case, iron loss is few and efficient is high, and can save resource.
As be wrapped in shown in the cross section of the coil 35c on the post 32c unshakable in one's determination; Be wrapped in each post 32a unshakable in one's determination, 32b, last coil and the post iron core of 32c and be adjacent to winding; In the present example; To be adjacent to by the primary winding 35c-1 that conductor tube constitutes and be wrapped on the post 32c unshakable in one's determination, overlapping winding secondary coil 35c-2 36 that coat by insulation, that constitute by conductor tube on said primary winding 35c-1, overlapping winding primary winding 35c-1 on said secondary coil 35c-2.That is the secondary coil 35c-2 that, is coated by insulation 36 is configured between the two-layer primary winding 35c-1.And, the electrically short circuit of the turn-to-turn of secondary coil 35c-2 through soldering welding etc.If in each primary winding, apply alternating voltage; Then in the post iron core, produce alternating flux because of the alternating voltage that applies; Thereby with the secondary coil of this alternating flux interlinkage in flow through electric current; Secondary coil produces Joule heat because of said electric current, and with the heating object in the conductor tube of the heat transferred secondary coil that sends (water or saturated steam).
In addition, in this example, primary winding is made as two-layer, when secondary coil is played insulation effect, has realized the Low ESRization of transformer device structure, two-layer but primary winding is not limited to, also can be one deck.In this case, primary winding is adjacent to and is wrapped on the post iron core.
UX on the terminal plate 34 is the leading-out terminal that is wrapped in the primary winding two ends on the post 32a unshakable in one's determination; VY is the leading-out terminal that is wrapped in the primary winding two ends on the post 32b unshakable in one's determination; WZ is the leading-out terminal that is wrapped in the primary winding two ends on the post 32c unshakable in one's determination, terminal UVW respectively with respectively being connected of three phase mains.
In described three-phase transformer structure; Between post 32a unshakable in one's determination and the post 32b unshakable in one's determination and between post 32b unshakable in one's determination and the post 32c unshakable in one's determination; Being provided with area of section is leakage magnetic circuit 33 (magnetic circuit as three-phase is observed, and leakage magnetic circuit unshakable in one's determination 33 is unshakable in one's determination in abutting connection with configuration with each post) unshakable in one's determination of post area of section 1/2 unshakable in one's determination.Shown in figure 11; Unshakable in one's determination 33 the time when being provided with as above leakage magnetic circuit; If for example be wrapped in the electric current that flows through a phase of three-phase alternating-current supply in the primary winding on the post 32a unshakable in one's determination; The major part of the magnetic flux that is then produced by applying of this electric current is walked around other post iron core and is flowed to leakage magnetic circuit iron core 33, and the said magnetic flux that flows to post 32b unshakable in one's determination, 32c is very faint.
More specifically, the state that flows through maximum magnetic flux in the leakage magnetic circuit of three-phase transformer occurs in and two applies rated voltage on mutually, when residue one is cut off mutually.The voltage-phase of this moment is: one is that Sin150 ° and another are Sin30 ° of 120 ° of delays mutually mutually; One is that Sin330 ° and another are Sin210 ° of 120 ° of delays mutually mutually, and said total magnetic flux becomes the value of the maximum magnetic flux that is no more than a phase when this voltage-phase.This external different combined in; When one being Sin30 ° and another when being the Sin (210 °) of 240 ° of delays mutually and one be Sin210 ° and another when being the Sin (30 °) of 240 ° of delays mutually mutually mutually, the total magnetic flux of this moment also becomes the value of the maximum magnetic flux that is no more than a phase.
If use formula to represent to be the phase angle of benchmark phase, the maximum magnetic flux that Φ is a phase with θ, then said formula is following:
Absolute value Φ Sin θ+Φ Sin (θ-120 °)＜absolute value Φ
Absolute value Φ Sin θ+Φ Sin (θ-240 °)＜absolute value Φ.
Described situation has represented that as long as the area of section of leakage magnetic circuit of each transformer is identical with the area of section of a phase of the post iron core that is wound with coil.Although respond to the induced voltage that produces half specified degree because of the faint magnetic flux that flows into other phases when non-loaded, induced voltage reduces to the degree that can ignore when load is arranged, and in practical application, does not have problems.In addition; If it is unshakable in one's determination that two positions between three post iron cores are provided with the half the leakage magnetic circuit of necessary area respectively; Then in the iron core of a horizontal row shape shown in Figure 8, distance fluctuation (ば ら つ I) minimum that the magnetic circuit from each to leakage magnetic circuit is long can realize the uniformity of magnetic flux flows.
