Embodiment

Hypermutation is the power coupler part between induction superimposer and klystron than pulse transformer, it is except transmission pulse power, also, for klystron filament supply provides path and realize the isolation of high-voltage pulse, under the cooperation of additional device (capacitor voltage divider, current transformer and pulse choking coil), complete the sampling task of pulse voltage, pulse current and the Quarantine Tasks of degaussing power supply simultaneously.Referring to Fig. 1,2 known, iron core 1 outside is evenly wrapped up by primary coil 3 and secondary coil 4, between primary coil 3 and secondary coil 4, insulated by insulated mounting plate 2, and the transformation device being integrally formed by connector 5 and securing member 6, transformation device is fixed on division board 8, and is electrically connected with the keyset 7 on division board 8, and keyset 7 is provided with electric component 10 by Quick connector 9 and division board 8 and is connected, electric component 10 is provided with two, is positioned at division board 8 both sides.

Describe in detail than all parts of pulse transformer with regard to hypermutation below;

The quantity of iron core 1 is calculated gained according to actual needs, and in Fig. 1,2, the quantity of iron core 1 is 3, and in order to make the efficiency of all solid state high voltage pulse adjuster high as much as possible, it is little that the loss of magnetic core should be tried one's best.The cross-sectional area of magnetic core should be determined by the volt-second characteristic of magnetic core.In addition, the voltage high-end due to the part of stack is higher, considers withstand voltage problem, and the inside radius of magnetic core should be enough large.According to above requirement, iron core 1 adopts the Fe-based amorphous large magnet ring iron core of band protection box, the electrical characteristic due to this kind of material: so in the situation that adding magnetic bias, the requirement of magnetic flux can well be ensured.Because material is very soft, be in layer to reel and form, add protection box at the outer surface of iron core, change internal structure for protecting it not broken by external environment factor, affect its performance.

Insulated mounting plate 2 adopts epoxy glass cloth laminated board 32408GB/T1303.1-98, as the term suggests this insulated with material is effective, and this strength of materials height can compare favourably with steel plate.

Primary coil 3 all adopts aluminium sheet 2A12(T4 with secondary coil 4) 55GB/T3880-97 fine finishining forms, and selects that to change material be because this material is heat-treatable strengthened aluminum alloy, through solution treatment, has higher intensity after natrual ageing; The electric conductivity of this material is good, lightweight; The most important thing is that this material has the machining property of good crystallized ability, can obtain various types of products.This hypermutation only has the thickness of 2.5 millimeters than the box body of pulse transformer, relatively generally speaking volume is larger, and box body thickness is too thin, and general material is difficult to process, or not at all easy flaw that processes can affect hypermutation than the performance of pulse transformer.

Connector 5 adopts aluminium sheet 2A12(T4) 10GB/T3880-97, select this material to be because the electric conductivity of this material is good, lightweight, for large scale system, reduce weight system itself is had to greatest benefit.To reducing raw-material cost, processing and manufacturing and landed cost, just saved human and material resources, financial resources cost to whole project, advocates the energy-saving and cost-reducing aim that country proposes.

Securing member 6 adopts GB securing member, purchase wide, procurement cycle is short and price is economical, for hypermutation facilitated than the processing and manufacturing cycle of pulse transformer.

Keyset 7 adopts copper coin H62 (Y), and electric conductivity is superior, can well connect into as a whole with Quick connector 9, there will not be the false phenomenon that connects, gently system loose contact, heavy the problems such as short circuit may cause unpredictable injury to system.

Division board 8 adopts poly (methyl methacrylate) plate (transparent), and the advantage of this material is one of best plastics of good insulation preformance, transparency.Both can do hypermutation than the strutting piece of pulse transformer; Can play again insulation effect, save and do separately the human and material resources cost insulating; Can play again the effect of photoscope, one act of its inner case is clear, and can watch easily at any time hypermutation than the situation of pulse transformer inside, again need not frequently be subject to the hardship of dismounting, assembling; After need not being frequently subject to dismounting, assembling, hypermutation also can be promoted accordingly than the life-span of pulse transformer, for client has saved cost.

Quick connector 9 can be realized fast insert-pull (being installation and removal), Quick connector 9 well links into an integrated entity with switch module or other electric elements, thereby make electric elements to carry out installation and removal with hypermutation than pulse transformer easily, offer convenience to installation and maintenance.

Hypermutation is as follows than pulse transformer manufacture method:

First before assembling, each parts are answered clean, and cleaning work table top;

Step 1, division board 8 is placed on work top, gradient that faces up; By keyset 7 be placed into division board 8 directly over, gradient that faces down, and to good installing hole, is fixed with sunk screw;

Step 2, by secondary coil 4 according to direction as shown be placed into keyset 7 directly over, have facing up of big groove, to good installing hole, be fixed with sunk screw;

Step 3, be a full circle put face-to-face 2 fan-shaped insulating papers 12 that cut in the big groove of secondary coil 4 after, measure-alike with big groove;

Step 4, the iron core 1 of band protection box is carefully put into secondary coil 4 stably, the gap of adjusting circumference place is identical, puts several places and fixes with silicon rubber 11 is uniform at iron core 1 upper surface of band protection box; Use same method that the iron core of 3 band protection boxes is installed and fixedly completed, notice that the top one deck band protects the upper surface of the iron core 1 of box not put silicon rubber 11 fixing, but put face-to-face several to being a full circle after the fan-shaped insulating paper 12 cutting, measure-alike with big groove, the number of plies is not rocked and is as the criterion in the inner chamber of primary coil 3 and secondary coil 4 with the iron core 1 of band protection box;

Step 5, insulated mounting plate 2 is put on secondary coil 4 through iron core 1, has finely tuned relative position, insulated mounting plate 2 and iron core 1 interference fit, well connect into as a whole with it;

Step 6, connector 5 is put into secondary coil 4 tops;

Step 7, to after good installing hole by primary coil 3 according to drawing direction, relative insulated mounting plate 2 tops that are put into of big groove face with secondary coil 4, to good installing hole, are fixed with pan head screw according to drawing;

Step 8, other accessories are installed on division board 8.

Insulating paper is the size cutting with secondary coil 4 inside according to primary coil 3 before assembling, is shaped as fan-shapedly, and 2 big grooves of merging into face-to-face a full circle and primary coil 3 and secondary coil 4 inside are measure-alike, quantity several.Because the big groove size of primary coil 3 and secondary coil 4 inside is too large, be cut into circle and be awkward, waste again insulating paper 12, reduce manufacturing cost; In addition cut 1 fan-shaped after, second just can be utilized previous fan-shaped edge, 1 of cutting is fan-shaped prunes and can be shaped a little, cutting successively so is one by one shaped, and has both saved the time, has saved again material.

By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
