Abstract

The utility model provides a ring-shaped electric reactor which comprises a reactor outer shell. A plurality of turns of toroidal coils which are evenly distributed along the circumference are arranged inside the reactor outer shell. Each toroidal coil is formed by straight spiral coils in a winding mode. A conductor of the toroidal coil is a hollow metal pipe. Cooling media are filled into the hollow metal pipe. The ring-shaped electric reactor is a hollow reactor, and can effectively solve the problem that external expansion of a magnetic field causes magnetism leakage by adopting the toroidal coils. In addition, due to the fact that conductors of the toroidal coils are hollow metal pipes, the conductors can achieve the effect of electric conduction, the cooling media can be filled into the conductors, the conductors has both an electric conduction effect and a cooling effect, the heat dissipation problem of a product can be effectively solved, other cooling devices are not needed, the size and the weight of the product are effectively reduced, and cost is reduced.

Description

A kind of annular reactor
Technical field
The utility model belongs to the reactor technical field, relates in particular to a kind of annular reactor.
Background technology
Air core reactor, stable because of its inductance characteristic, the size of inductance value does not change with size of current, is widely used in big current domain.But air core reactor is not because there is closed iron circuit, and the reactor stray field is very big, influences peripheral equipment particularly normal operation and the work of magnetic induction part.And railway applications-air core reactor is high because it requires EMI (electromagnetic compatibility), and the application of air core reactor in this field is subjected to great limitation, and this is mainly caused by the reactor own characteristic.
Present air core reactor main defective that exists in application has: (1) reactor adopts hollow-core construction, and stray field is big, influences peripheral equipment and normally moves; (2) the reactor leakage field is big, to having the cardiac pacing personnel fatal harm is arranged, and must add heavy steel plate and solve the leakage field problem, and product weight transfinites; (3) in big electric current application, air core reactor produces with the common mode cooling, and volume is big, and weight is big, the cost height.The railway applications reactor also must satisfy the shock and vibration test requirements document simultaneously.
Summary of the invention
The utility model has solved that the leakage field that prior art hollow core reactor exists is big, product weight and volume is big, the high technical problem that can not be used widely at railway territory of cost, propose a kind of annular reactor with new structure, it can satisfy the various requirement of railway applications reactor.
The technical solution of the utility model is:
A kind of annular reactor, described annular reactor comprises the reactor shell, be provided with some circles in the reactor shell along the equally distributed loop coil of circumference, described loop coil is formed by the coiling of straight shape helical coil, described toroidal conductor is hollow metal tube, is used for feeding coolant in the described hollow metal tube.
As further improvement of the utility model, the surface of described hollow metal tube has nickel coating; Described hollow metal tube is hollow copper tubing or hollow aluminum pipe.
As further improvement of the utility model, be provided with insulating barrier between every circle loop coil.
As further improvement of the utility model, the outer surface of reactor shell has vacuum casting layer or vacuum paint dipping layer.
The annular reactor that the utility model provides, it still is air core reactor, but it is by adopting loop coil, and namely coil is circular ring structure, and therefore can effectively solve magnetic field extends out the problem that causes leakage field; In addition, because the conductor of coil is hollow metal tube, so it can realize electric action, can feed coolant again, namely have the effect of conduction and cooling concurrently, can effectively solve the product heat dissipation problem, and need not other cooling device, thus effectively reduce small product size and weight, reduce cost.
Description of drawings
The structural representation of the annular reactor that Fig. 1 provides for the utility model.
The use state diagram of the annular reactor that Fig. 2 provides for the utility model.
Wherein, 1---the reactor shell, 2---loop coil, 3---busbar, 4---water pipe head.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides a kind of annular reactor, as shown in Figure 1, described annular reactor comprises reactor shell 1, is provided with some circles in the reactor shell 1 along the equally distributed loop coil 2 of circumference, and every circle loop coil 2 is all by forming straight shape helical coil bending back coiling.Simultaneously, in the utility model, the conductor of loop coil 2 is hollow metal tube, and the conductor of the straight shape helical coil that namely adopts is hollow metal tube.Be used in the described hollow metal tube feeding coolant, make this coil to conduct electricity, can play the effect of cooling again.For example, when coolant adopted water, in the utility model, loop coil 2 was designated as the water power integrative-structure, thereby can effectively solve the product heat dissipation problem.
As a kind of preferred implementation of the present utility model, the surface of described hollow metal tube has nickel coating (not shown in the accompanying drawing), and the effect of this nickel coating is to prevent oxidation on metal surface, influences the current water resistance.In the utility model, consider the satisfactory electrical conductivity of loop coil 2, under the preferable case, conductor (being hollow metal tube) total in the described loop coil is hollow copper tubing or hollow aluminum pipe.
Be provided with insulating barrier between every circle loop coil, with reinforced insulation.The insulating material that insulating barrier adopts is various insulating material commonly used in the prior art, and the utility model does not have particular determination.
As another kind of preferred implementation of the present utility model, the outer surface of reactor shell has vacuum casting layer or vacuum paint dipping layer (not shown in the accompanying drawing).At this moment, reactor shell 1 and annular reactor integral intensity are promoted greatly, and the annular reactor that makes the utility model provide can satisfy the structural strength requirement of railway business product integral body.
The annular reactor that the utility model provides in use, as shown in Figure 2, the conductor (being hollow metal tube) of loop coil 2 is connected with water pipe head 4, can in hollow metal tube, feeds coolant water, thereby the full annular reactor is cooled off; Simultaneously, convenient follow-up line is drawn in conductor and busbar 3 welding of loop coil 2.
The annular reactor that the utility model provides, it still is air core reactor, but it is by adopting loop coil, and namely coil is circular ring structure, and therefore can effectively solve magnetic field extends out the problem that causes leakage field; In addition, because the conductor of coil is hollow metal tube, so it can realize electric action, can feed coolant again, namely have the effect of conduction and cooling concurrently, can effectively solve the product heat dissipation problem, and need not other cooling device, thus effectively reduce small product size and weight, reduce cost.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
