Work has multiple through hole, for the heat radiation of intensifier coil 1.Nylon base 2 Surface Machining has counter sink, is used for putting into nut;Plug screw 6
For trapezoidal revolving body, it is used for blocking the nylon base 2 surface big end of counter sink, the boss at nylon base center and hub of a spool through hole
For matched in clearance, in nylon base 2, there is multiple nut, fix for drawing the connection of joint and discharge coil.Anelectrode 4 is ball
Clapping shape structure, dead ring 3 is enclosed within the coil 1 big end of step, anelectrode 4 and coil 1 step small end elastic conjunction, negative electrode 7 and line
The outer ring of circle 1 is spirally connected;Dead ring 3 it is separated with, to ensure the axial distance of electrode and coil between anelectrode 4 and coil 1.
The process made for discharge coil is: this example discharge coil selects red copper disk material, and to surface
Greasy dirt and oxide layer are purged processing;Coil outer diameter is designed as Φ 90mm, and single turn copper strips thickness is 2mm, and turn-to-turn is away from for 1mm.
Coil is fixed on nylon base, and nylon base external diameter is Φ 100mm, and center-hole diameter is Φ 18mm.Hub of a spool bore dia
For Φ 22mm, 8 circles are cut in the processing of copper dish.
First uniform processing φ 3 through hole in copper dish circumference, between holes, angle is 60 °, and the position of processing through hole is avoided
The installation site of negative electrode 7, then carries out linear cutter and becomes coil 1.Anelectrode 4 is racket-shaped, first by dead ring 3 before assembling
Being enclosed within the coil 1 big end of step, anelectrode 4 and coil 1 step small end are elastic conjunction, then step small end opening part riveting are put down,
Complete the fabrication and installation of anelectrode 4.Nylon base 2 Surface Machining has three counter sinks, and the nut of 3 M6 is imbedded nylon respectively
In the macropore of base 2 counter sink, burying and block counter sink macropore with plug screw 6 the most afterwards, blend compounds water seal is dead.
The endoporus of coil 1 and nylon base 2 boss are matched in clearance, and after installation, racket-shaped anelectrode 4 just imbeds nylon
In base 2 facing groove.Negative electrode 7 uses brass screw be connected and be welded with coil 1 outer ring, has both ensured that negative electrode 7 is with coil 1 even
Connect intensity, also ensure that electric conductivity.Between negative electrode 7 and the anelectrode 4 of installation, angular range is 70 ° to 80 °.
Prepare 6 a length of 38mm, the pin of a diameter of 3mm, insert after coating lubricating oil in the louvre of coil 1, prevent
Insulating cement envelope real louvre during cast.Being enclosed within the big end stand rank of nylon base 2 with baffle plate 5 before Jiao Zhu, anelectrode 4 lacks from baffle plate 5
Extend out at Kou.With adhesive tape, with nylon base 2 junction, baffle plate 5 being wound around sealing, when preventing from pouring into a mould, insulating cement is from connecting gap
Place flows out.
Insulating cement is slowly poured in coil 1, until insulating cement covers coil 1, when insulating cement is poured into from coil-end
Cast is stopped time at face 3~5mm.Coil 1 after cast is put into vacuum machine and is extracted vacuum, it is seen that insulating cement end face constantly has
Bubble is emerged, and in time stopping producing bubble, takes out coil 1 and puts into dehydrator drying.After 24 hours, coil 1 is taken out, insulation
After adhesive curing, take off baffle plate 5 and the pin in louvre.Coil end face processing cart is put down, completes the making that discharge coil makes.
Carry out voltage tester.Discharge cable is connected respectively the anelectrode 4 of discharge coil, negative electrode 7, adding at 1000V
Carry under voltage, through load test more than 3000 times, carry out detecting the discharge coil life-span, complete test.
