Abstract
The utility model discloses a reactor which is provided with a coil, an insulating part, a base bottom, a clamping device and a junction device. The reactor is characterized in that the core column of a magnetizer is arranged in the coil, and the cross-sectional area of iron core discuses at the upper and the lower ends of the core column magnetizer is larger than that of another iron core discus at the middle part; a magnetic conducting barrel made of the magnetizer is arranged on the outer side of the coil; the core column, the coil and the magnetic conductive barrel are homocentric; and the head end or the tail end of the coil is connected with the core column magnetizer. The reactor has the advantages of low wastage, can prevent outward leakage of a magnetic field , and can be applied to electric power systems.
Description
(1), technical field:
The utility model reactor relates to the reactor in the electric power system.
(2), background technology:
The reactor that is installed at present in the electric power system mainly contains air core reactor, iron-core reactor and shell type reactor.The air core reactor winding volume is big, loss is high, and magnetic field is to external leakage, to environment and human body harmful during operation.The iron core of iron-core reactor has a plurality of gaps, and between each cake of core limb and be difficult to fixedly between core limb and the iron yoke, running noises is bigger.Shell type reactor silicon steel sheet materials are more, complex process, and middle-size and small-size reactor adopts few.Next has half core type reactor and shielding air core reactor.Though half core type reactor loss decreases, and reduces the wastage 30% approximately, fail to solve the problem of magnetic field to external leakage, the loss of protected type air core reactor is still bigger.Also there is the significantly problem that reduces the wastage inadequately in the scheme of the patent ZL200420005605.1 of the utility model scheme inventor original application in addition.
(3) summary of the invention
The purpose of this utility model is the shortcoming that overcomes above reactor, makes its loss little, and magnetic field reduces running noises not to external leakage.
Scheme of the present utility model is the new departure that has carried out great technological improvement on the basis of the former patent ZL200420005605.1 of this programme inventor, and this practical plan is more remarkable than former patent energy-saving effect.Concrete solution of the present utility model is: it has coil, insulating part, base, clamping device, termination, it is characterized in that in the coil it being the stem that magnetic conductor is made, the coil outside is the magnetic conductive cylinder that magnetic conductor is made, stem, coil, magnetic conductive cylinder three are concentric, the stem magnetic conductor is made up of a plurality of gaps and a plurality of cake unshakable in one's determination, and the gap material is a non-magnet material.The feature of stem cake unshakable in one's determination be the cake area of section unshakable in one's determination at both ends greater than middle part cake area of section unshakable in one's determination, certain insulation distance is arranged between coil and stem and the magnetic conductor, insulation distance should satisfy the requirement of relevant voltage grade dielectric strength.Materials such as the magnetic conductor available silicon steel disc of stem and magnetic conductive cylinder, non-crystaline amorphous metal are made.The feature of reactor lead-in wire is that the head end or the tail end of coil is connected with the stem magnetic conductor.
Because the magnetic conductive cylinder that the utility model has adopted stem that magnetic conductor makes and magnetic conductor to make has reduced main flux loop magnetic resistance, especially the cake area of section unshakable in one's determination of stem two ends magnetic conductor is bigger, further reduced main flux by the magnetic resistance of stem to magnetic conductive cylinder, the closed-loop path that the main flux of reactor constitutes main flux jointly by stem and stem to the space and the magnetic conductive cylinder of magnetic conductive cylinder, it is few to leak into the outside magnetic flux of magnetic conductive cylinder, thereby has alleviated the injury of magnetic field to environment and human body.Because in the coil is the magnetic conductor stem, thereby compare with dry-type air-core reactor, the required number of turn can reduce when same nominal capacity, same nominal reactance situation, thereby reduced the loss on the coil, the total losses of reactor also can reduce, the head end of coil or tail end are connected with the stem magnetic conductor, have avoided stem to be in floating potential.
Be described in further detail below in conjunction with the concrete mode of accompanying drawing utility model.

(5) embodiment
Single-phase reactor as shown in Figure 1, stem 1 is positioned at the center of reactor, stem 1 outside is a coil 2, coil 2 is to be fixed on stem about in the of 1 between two heavy in section area cakes unshakable in one's determination, the outside of coil 2 is magnetic conductive cylinders 3, stem bolt and nut 6 clamps the stem 1 and the folder 4 that insulate up and down, and by cross-over block 7 fixed coils 2, bolt and nut 8 plays fixing insulate up and down folder 4 and magnetic conductive cylinder 3.Base insulated leg 5 fixing single-phase reactor device bodies.The lead-in wire 9 of coil 2 is fixed on the stem bolt and nut 6, and stem bolt and nut 6 is used electric conducting material with each cake unshakable in one's determination of stem and is connected.The lead-in wire 10 of coil 2 is fixed on the bolt and nut 8. and the inwall of magnetic conductive cylinder 3 is insulating cylinders 12, be used for fixing the magnetic conductor of magnetic conductive cylinder, the magnetic conductor of magnetic conductive cylinder is provided with insulation fracture 11 in case of necessity, is overlapped to form the closed-loop path mutually in order to the machined burrs that prevents magnetic conductor such as silicon steel sheet.Coil 2 should be considered by the correspondent voltage grade with the insulation level of stem 1 and magnetic conductive cylinder 3.It more than is the general structure of reactor.
Stem as shown in Figure 3 (being the stem 1 of Fig. 1) is made of big cake unshakable in one's determination 13 and middle part cake 14 unshakable in one's determination of the area of section at two ends up and down and the gap 15 between the cake unshakable in one's determination, it is characterized in that the area of section of the cake area of section unshakable in one's determination at two ends up and down greater than middle part cake unshakable in one's determination.Cake unshakable in one's determination center is porose to be convenient to screw rod and to pass it is stepped up.Cake unshakable in one's determination can be made radial cake unshakable in one's determination, also can select the laminated core cake for use.Gap 15 is used non-magnet material and is made.
The utility model can be made dry reactor, also can make the oil immersed type reactor, and three single-phase reactors can connect into three-phase reactor.
