（3）By designing damper box and raised head bolt, creep age distance, reinforced insulation intensity, it is to avoid water on the one hand can be increased
Road, on the other hand, carries out debugging by raised head bolt and so that having rational gap between two pieces of iron cores, and then can improve product
Performance reliable and stable；
（4）By filling insulating resin between pour mass and iron core, vacuum pouring encapsulated moulding is so that overall compact is hard
Gu, will not produce loosening.
Brief description
Fig. 1 is the structural representation of this utility model embodiment.
Specific embodiment
Below with reference to Figure of description and specific embodiment, this utility model is described in further details.
As shown in Figure 1：A kind of new compensation reactor, the iron core 2 including pour mass 1 and in pour mass 1, iron core 2
It is the R shaped iron core being turned to by banding stalloy, and iron core 2 is to be cut into the R shaped iron core being formed after two halves；Namely
Say, the present embodiment be the R shaped iron core being turned to by stalloy after heat treatment, cut into symmetrically the same two piece c-type iron core, and
Further in conjunction with forming R shaped iron core, between two pieces of c-type iron cores, rational gap 3 is filled by cable insulating paper, to meet reactor
The measurement requirement of the D.C. resistance of winding.The gap 3 of the present embodiment is preferably 1.8mm, and that is, the filling thickness of cable insulating paper is
1.8mm.
The present embodiment by existing long rectangle iron core is changed over R shaped iron core, due to long rectangle iron core section be in square
Shape, the section of R shaped iron core is rounded, and, under same sectional area, its R shaped iron core is than the perimeter of section of long rectangle iron core for the two
Little, then R shaped iron core can mitigate 1/4 than long rectangle iron core weight, greatly save stalloy and copper product, and then save one-tenth
This.
In the present embodiment, the middle part of iron core 2 is horizontally connected with fastener 4, and fastener 4 is arranged with the first skeleton 5, iron core
It is arranged with the second skeleton 6 on 2；All it is wound with coil windings 7, coil windings 7 are included from interior on first skeleton 5 and the second skeleton 6
To the outer main winding of coiling successively and regulation winding, between main winding and regulation winding, it is also filled with cable insulating paper.
Because iron core 2 is in cylinder, the second skeleton 6 that it is set on iron core 2 is also the cylinder being adapted with core configuration
Shape structure, and the girth of tubular structure is less by 1/6 than rectangular perimeter, thus having saved material, and the external diameter of coil also can be big
Reduce greatly, 1/3 copper cash can be saved.First skeleton 5 of the present embodiment and the second skeleton 6 are tubular structure.
The coil winding number of turn adjusting winding accounts for the 20% of the main winding winding number of turn.
In the present embodiment, the upside of pour mass 1 is provided with damper box 8, is provided with six raised head bolts 81 in damper box 8, and that is, two
Block iron core respectively accounts for three raised head bolts 81.The top of damper box 8 is provided with lid, forms an airtight cavity, and inner chamber is concave.
By arranging damper box 8, not only can increase creep age distance, reinforced insulation intensity, moreover it is possible to avoid water route, will not produce electric discharge existing
As；And error transfer factor can be carried out by raised head bolt 81.
In the present embodiment, between pour mass 1 and iron core 2, it is filled with insulating resin, by vacuum pouring encapsulated moulding.This
Sample, iron core 2 can be integrally fixed with pour mass 1 so that overall compact is firm, will not produce loosening, during life-time service
Be not in insulation degradation phenomenon, product insulation is sufficiently stable, and ensure that product has reliably moistureproof anti-condensation performance,
Electrical leakage, discharge problem will not occur because of the condensation of product surface, considerably increase mechanical strength and the resistance to shorting of coil windings
Ability.
Low voltage outlet terminals 9 are drawn in the lower end of iron core 2, and low voltage outlet terminals 9 are directly led out by insulating soft wire, access to
On electromagnetic unit outlet board.
The present embodiment passes through for iron core 2 to be designed as divided R shaped iron core, and by twin coil through pair skeletons carry out around
System, and debugged by raised head bolt 81, make iron core have rational gap, meet every technical parameter, adapted fastening
After dried, with insulating resin vacuum around forming the more reliable and more stable compensation reactor of full encapsulation, performance.For example this is mended
Repay reactor in CVT electromagnetic unit, and by its inductance value be incorporated to intermediate transformer once with Secondary Winding in, to eliminate
The change in voltage that the change of capacitive reactance pressure drop secondary load causes, makes voltage keep stable.
