Fig. 1 is structural representation of the present invention;
In figure, 1 coil, 2 iron cores, 3 radiators, 4 top boards, 5 upper clamping pieces, 6 insulators, 7 insulation support plates, 8 water pipes, 9 connect busbar, 10 damping resistances, 11 intake-outlet connectors, 12 lower platens, 13 lower clamping pieces.
Embodiment
For ease of understanding technical scheme of the present invention, below in conjunction with accompanying drawing, wherein involved technology contents is described further.
As shown in Figure 1, a kind of converter valve water-cooled saturable reactor, it comprises two lower clamping pieces 13 of four eradication edge support plates 7, two upper clamping pieces 5 of cross beam type and correspondence, the top board 4 of insulation, the lower platen 12 of insulation, coil 1 and iron core 2.The two ends up and down of described insulation support plate 7 are fixedly connected on the end of described upper clamping piece 5, lower clamping piece 13 respectively by bolt.Described top board 4 bolt is fixedly connected in the middle part of described two upper clamping piece 5 upper surfaces, and accordingly, described lower platen 12 bolt is fixedly connected in the middle part of described two lower clamping piece 13 lower surfaces.Described coil 1 is two groups, and the insulator 6 respectively by column type is fixedly mounted between described upper clamping piece 5 and lower clamping piece 13.Described iron core 2 to be coupling in respectively in described coil 1 and to be fixed between described top board 4 and lower platen 12.Be coupled with many group iron cores 2 in each coil 1, and often organize the CD type structure that iron core 2 is make-up, fix with stainless steel band, and air gap plate is set between make-up end face.
Described coil 1 adopts the coiling of water-cooled busbar, and coil 1 adopts vacuum casting technique to pour into a mould in advance forms.
Be provided with a water-filled radiator 3 between every two groups of iron cores 2, and whole reactor adopts water-cooling.The water pipe 8 connected in water circulation system separates by connecting busbar 9, and described connection busbar 9 is fixed on the lower end of this converter valve water-cooled saturable reactor, and water inlet, delivery port are arranged on the import and export connector 11 that is fixed on and connects on busbar 9.The concrete type of attachment that water-cooled connects is existing technological means, as long as this invention takes water cooling method, can arrange this part supplementary structure for a person skilled in the art.
Described iron core 2 adopts high frequency good, and the 0.05mm grain-oriented silicon-iron strip of annealed process is fixed.In order to draw the damping loss heat of described iron core 2, damping resistance 10 and two circle secondary coils are set up, described secondary coil is out connected with described damping resistance 10 from solderless wrapped connection an arm of described iron core 2 one groups of CD type structures, and described damping resistance 10 is fixed on described lower clamping piece 13 upper surface.
