Saturable reactor can be divided into simplex winding and double winding two classes again according to the number of winding, double winding is meant except inductance coil, other establishes a damping winding coil, the coil 1 of saturable reactor and iron core 2 are encapsulated within the shell as shown in Figure 1, and coil 1 two is connected with water pipe head 5 and copper bar 6; Iron core 2 adopts up and down, and U type structure is buckled between the inside and outside wall of coil 1 in pairs, open with air gap pad 8 pads in the U type make-up gap of every pair of iron core 2, iron core 2 usefulness stainless steel bands 9 are fixing subsequently, the every pair of iron core coil circumferentially between separate with cushion block 3, the coil 1 that iron core 2 is installed at last is placed on casting epoxy resin 7 in the anchor clamps.But it is all very complicated that the shortcoming of the saturable reactor of this structure is electrical design and mechanical strength design.
The utility model content
In order to overcome the defective of prior art, the purpose of this utility model is to provide a kind of saturable reactor for direct-current converter valve that helps implementation structure design and industrialization production.
For this reason, the utility model proposes a kind of saturable reactor that is used for DC converter valve, comprise coil, epoxy resin, iron core, metal folder, air gap and copper bar, it is characterized in that: described coil adopts the hollow aluminum pipe to constitute, described iron core has C type structure and adopts distributed arrangement, and the week that described iron core is buckled in coil in pairs makes progress; Has air gap between the iron core of described paired snapping; A copper bar is respectively welded in two ends at coil.
Wherein, for the ease of fixing and lifting, described coil winding becomes runway shape structure.
Wherein, fix by epoxy resin between the circle of described coil and the circle and insulate, epoxy resin has certain elasticity, can reduce reactor in the vibration of run duration and reduce noise.
Wherein, the surperficial full-filling of described epoxy resin has conductive metal layer, and described iron core is attached at the surface of conductive metal layer, is buckled in the winding outside of resin parcel in pairs.
Wherein, the outside of described iron core adopts C type metal folder to carry out fastening.
Wherein, many iron cores to the sealing coupling upwards are being set the week of described coil.
The beneficial effects of the utility model are:
1, saturable reactor of the present utility model adopts distributed iron core to arrange, just can change inductance parameters by changing the iron core logarithm;
2, the paired snapping of the iron core of saturable reactor of the present utility model can change inductance parameters by changing air gap thickness;
3, the hollow aluminum pipe of saturable reactor of the present utility model has been simplified cooling water channel greatly as cooling-water duct;
4, the coil of saturable reactor of the present utility model adopts runway shape structure, and this kind is simple for structure light and handy; In addition, owing to adopt runway shape structure,, be convenient to fixing and lifting so the relative two sides of coil is a linear structure.
