Detailed description of the invention
As a example by the magnet of 4 loop constructions, the invention will be further described below.
Magnet coil shown in Fig. 1 and Fig. 2 uses flat copper enamel-covered wire coiling to form, and enamel-covered wire cross section is 1mm*4mm.Coil
1 coiling 10 layers, every layer of 12 circle；Coil 2,3,4 respectively coiling 6 layers, 4 layers and 3 layers, every layer is 12 circles, 4 so turned to
Relatively, maximum induction is less than 2 with the ratio of minimum inductance to the inductance of coil.The coiling of adjacent windings is in opposite direction, both side
Bridging coil time connection, reduce again adjacent windings interlayer insulating requirements.The internal cavities of coil rack 0 is tested exactly
Space, produces the place of high-intensity magnetic field, a diameter of 12mm of cavity.
During coil winding, coil rack 0 is rotatable around its axis, and close being wound on coil rack 0 of enamel-covered wire obtains coil 1, so
After close in the outside of coil 1 lay out coil 2, rotation side when the rotation direction of coil rack and coiling 1 during coiling 2
To on the contrary.Origin or beginning 2A of coil 2 is close with the end 1B of coil 1, and they are positioned at same one end of coil the most in the axial direction, along footpath
The outside of 1B it is positioned to 2A.In the outside coiling 3 of coil 2, the outside coiling 4 of coil 3, the coiling side of adjacent windings
To all contrary, the origin or beginning of later coil is all close with the end of previous coil.Owing to the inductance of coil increases with coil diameter
Adding and increase, so in order to inductance L1, L2, L3 and L4 of making 4 coils are close, the number of turn of 4 coils also differs, but by
In gradually decrease to the outer number of turn.Resistance R1, R2, R3 and R4 also difference of 4 coils is little.
Coil is for producing impulse magnetic field, and when peak field, coil inside is by the electromagnetism outside along radius
Power effect, calculates and shows that innermost layer coil is reached 1000MPa by outside stress, much larger than copper when producing 50T magnetic field
Tensile strength.In order to avoid copper cash is pulled off, use outside coil, be wound around carbon cloth reinforced method.It is wound around multilamellar carbon fine
Wei Bu reaches adequate thickness, just can retrain coil, make it can not outward expansion, copper cash would not be pulled off.I.e. at coil 4
Outside compact winding carbon cloth, thickness depends on magnetic field size to be produced, to guarantee that copper cash will not be pulled off as principle,
The present embodiment uses thickness to be 30mm.Overlapping a steel pipe in the outside of carbon cloth the most tightly, reinforce further, method is first
The magnet coil comprising carbon cloth is chilled to below zero centigrade, inside radius is equal to the steel of carbon cloth outer radius simultaneously
Pipe is heated to more than 100° centigrade, then rapidly by hot steel pipe socket outside carbon cloth, will be tightly after waiting steel pipe cooling
Wale coil, play reinforce and about wire bushing expand effect.Coil rack, coil, carbon cloth and steel pipe constitute magnet,
Tube material is usually rustless steel, and coil rack uses nonmetallic materials to make.
The present invention realizes the miniaturization of device by using multi-coil structure.Because when line footpath one timing of coiling,
Equivalent inductance after the directly parallel connection of multiple coils is less than the inductance value of single coil, and same capacitance voltage can inspire higher
Electric current, thus produce higher peak field.Inductance between different coils close to time, the current impulse width in each coil
Spend also close to, the magnetic field of generation is overlapped mutually, affects, and is conducive to improving pulsed magnetic field waveform, the most each coil temperature rise and suffered
Stress is the most more uniform.But, need during due to coiling to consider that every layer line circle, as far as possible around expiring, taking up, it is also contemplated that coil draws
Outlet position, so multiple coils of actual coiling are often difficult to accomplish that the inductance making them is equal.For coil number more than 4
Magnet, even if the ratio making maximum induction and minimum inductance is also relatively difficult less than 2, need through a large amount of repetition tests
Find the optimal number of turn and size.So, after taking into account consideration many factors, this patent requires that in a wire loop maximum induction is with minimum
The ratio of inductance should be less than 4, and the inductance of each coil is closer to the best.The present invention uses the purpose of multi-coil structure to be different from
The purpose of documents used multi-coil structure in aforementioned background art, the present invention is in order to by reducing total equivalent inductance
Amount, it is achieved just can produce the biggest peak field with less storage capacitor, is finally reached the purpose reducing device volume, because
Electric capacity its volume the least is the least.Multi-coil structure employed in aforementioned comparison's file is not to reduce total equivalent electric sensibility reciprocal to be
Purpose, the inductance differences of each coil is very big, and the inductance of exterior loop is much larger than the inductance of interior loop.
Magnet coil is connected with energy-storage capacitor module by IGCT, constitutes the core of impulse magnetic field device, electric capacity
Device module uses high-quality electrolysis condenser to consist of connection in series-parallel.Fig. 3 to Fig. 7 gives the connection electricity of multitude of different ways
Road.
Fig. 3 is simplest connection, and IGCT Q1 and Q2 parallel connection are to expand peak current capability, if single brilliant lock
Pipe allows the maximum current passed through more than true peak electric current, then have only to an IGCT；If two IGCTs are also
Connection is not met by peak current requirements, then need to use more IGCT in parallel.4 coils are the most in parallel, bridging coil
Equivalent inductance less than the inductance of single coil.In the case of the magnet coil of same volume and same energy-storing capacitor module, electricity
The peak field that the coil feeling the least produces is the strongest.The method of attachment of coil is: 1A, 2B, 3A are connected together with 4B and
Connect the negative pole of capacitor module, 1B, 2A, 3B are connected together and connects the negative electrode of IGCT with 4A.The control of two IGCTs
Pole processed connects together, Synchronization Control turn on thyristors, and capacitor module produces strong pulsed magnetic field to coil discharge.Afterflow two pole
Pipe D01 and continued flow resistance R01 is to prevent the electric current in coil to capacitor module C1 reverse charging.
In Fig. 4 circuit, each IGCT connects 2 coils.If two IGCTs simultaneously turn on, its effect and Fig. 3 phase
With, i.e. it is equivalent to 4 coils from parallel connection of coils, because being equivalent to a wire during turn on thyristors.If two IGCTs are by single-chip microcomputer
Control successively conducting, then can improve pulse current waveform, i.e. improve pulsed magnetic field waveform, make pulse broaden, but peak field
Can reduce.Owing to the time difference of successively conducting is the least, 4 coils belong to quasi-parallel way.The equivalent inductance of bridging coil is less than
The inductance of single coil.The method of attachment of coil is: 1A with 2B is connected together and connects the negative pole of capacitor module；1B
Connect together and connect the negative electrode of Q1 with 2A；3A with 4B is connected together and connects the negative pole of capacitor module；3B and
4A connects together and connects the negative electrode of Q2.
In Fig. 5 circuit, containing two capacitor modules, each module is to two coil power supplies.Compared with Fig. 4, waveform
Improve more flexible.The method of attachment of coil is identical with Fig. 4.Sustained diode 02 and continued flow resistance R02 are to prevent in coil
Electric current to capacitor module C2 reverse charging.
In Fig. 6 circuit, capacitor module is as Fig. 5, and the method for attachment of coil is identical with Fig. 3.
In Fig. 7 circuit, each capacitor module only by an IGCT to a coil discharge, improve the flexible of waveform
Property is the highest.Each capacitor module is also connected to fly-wheel diode and continued flow resistance, prevents electric capacity reverse charging.The company of coil
The method of connecing is: 1A, 2B, 3A are connected together and connects the negative pole of capacitor module with 4B, 1B meets the negative electrode of IGCT Q1,2A
Connecing the negative electrode of IGCT Q2,3B connects the negative electrode of IGCT Q3, and 4A connects the negative electrode of IGCT Q4.
The method of attachment of above-mentioned coil can reduce the insulating requirements between adjacent windings, because working as coil simultaneously or nearly
When simultaneously turning on, the potential difference between adjacent windings adjacent wires is the least, and coil is not easy breakdown.Each coil conducting time
The magnetic direction produced on axis is identical, and superposition obtains high-intensity magnetic field.
Above-mentioned only as a example by the magnet of 4 loop constructions, illustrate the implementation of the present invention.Indeed, it is possible to there are other
The magnet of the coil composition of number, the most above-mentioned magnet removes coil 3 and coil 4, then constitutes the magnet of a two coil configuration.
Two coils are the most in parallel, i.e. 1A with 2B connected together and connect the negative pole of capacitor module, 1B and 2A is connected to one
Play and connect the negative electrode of IGCT.During turn on thyristors, the magnetic direction produced on axis in two coils is identical, and superposition is produced
Raw high-intensity magnetic field.For the magnet of two coil configuration, need to be wound around reinforcement material in the outside of coil 2, be i.e. wound around carbon cloth and
Steel pipe.In above-described embodiment, it would however also be possible to employ other high-strength materials replace carbon cloth and steel pipe, as reinforcement material.
The number of magnet coil can have 5,6,7,8 ... etc., it is critical to meet the coiling side of adjacent windings
To on the contrary, the origin or beginning of later coil is near the end of previous coil.The magnet of same volume, the number of coil is the most, always
Equivalent inductance is the least, and in the case of storage capacitor energy storage is certain, the peak field of generation is the strongest.The inductance of each coil is as far as possible
Close, inductance maximum in the most multiple coils should be less than 4 with minimum inductance ratio, the current impulse width in the most each coil
Degree relatively, and the size of electric current also close to.Otherwise, the minimum electric current in inductance coil is more than the electricity in other coils
Stream, causes temperature rise too high and stress is excessive, the most damaged.
In above-mentioned specific embodiment, the number of turn of coil every layer is identical, is all 12 circles, depends on the shape of coil rack.Real
Allow every layer of number of turn difference on border, such as, can make the internal layer every layer number of turn a little less, the coil that every layer, the outside number of turn is more.
The sectional dimension of copper cash used by each coil can also be different.
