Further improvement as above-mentioned technical proposal：

The overcoat is silastic-layer.

The overcoat is epoxy resin layer.

The coil is equipped with insulating base in both sides up and down, and the insulating base is provided with detent, and the coil is installed on In the detent.

Also include being used for the shielding construction for shielding leakage field.

The shielding construction includes upper barricade, lower barricade and the company for connecting upper barricade and lower barricade Connected components, the upper barricade are covered in the insulating base upper surface of upside, and the lower barricade is covered in the described of downside Insulating base lower surface.

The upper barricade is irony magnetic conductive board or silicon steel plate.

The connection component includes connecting screw and a pair of clamp nuts on connecting screw, on the connecting screw End is fixedly connected with the upper barricade, and lower end passes through the lower barricade, and the lower barricade is located in a pair of fastenings Between nut.

The shielding construction includes shield shell, and coil described in each cake and the insulating base are located at the shield shell It is interior.

The terminal box includes box body and at least one short circuit copper bar in box body, and coil described in each cake passes through described Short circuit copper bar realizes short circuit.

Compared with prior art, the utility model has the advantage of：Track traffic disclosed in the utility model is with non-maintaining Air reactor, its winding are made up of the coil of each cake independence, and each cake coil surface pours overcoat so that each cake coil with it is outer Portion's environment isolation, can effectively completely cut off the influence to coil such as dust, realize that exempting dedusting in life cycle safeguards, reduces dimension Protect workload and maintenance cost.When voltage, current anomaly cause winding insulation breakthrough and scaling loss, it also can timely pass through replacing Corresponding coil quickly resumes operation.

Embodiment

The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.

Fig. 1 to Fig. 6 shows a kind of embodiment of the present utility model, the non-maintaining hollow electricity of the track traffic of the present embodiment Anti- device, including winding 1 and for obtaining being expected the terminal box 2 of inductance to the short circuit of winding 1, winding 1 includes ten cake coils 11, respectively The surface of cake coil 11 has poured overcoat（In order to be shown clearly in the internal structure of coil 11, overcoat not shown in figure）.Line Circle 11 in specific make, can first coiling lopping, then carry out pouring to form overcoat.

The non-maintaining air reactor of the track traffic, its winding 1 are made up of the coil 11 of each cake independence, each cake coil 11 Surface pours overcoat so that each cake coil 11 and external environs, can effectively completely cut off the shadow to coil 11 such as dust Ring, realize that exempting dedusting in life cycle safeguards, reduces maintenance workload and maintenance cost.When voltage, current anomaly cause around Group insulation is broken through during scaling loss, also timely can quickly be resumed operation by changing corresponding coil 11.

As further preferred technical scheme, overcoat is silastic-layer or epoxy resin layer, has well dust-proof Water resistance, the dedusting that can be born in life cycle safeguard there is good heat dispersion again, while protection is realized, Advantageously ensure that equipment is reliably run for a long time.

As further preferred technical scheme, in the present embodiment, coil is equipped with insulating base 3 in both sides about 11, insulation Seat 3 is provided with detent 31, and coil 11 is installed in detent 31.The mounting structure is simple, reliable, be advantageously implemented around The quick-assembling of group 1.

In the present embodiment, track traffic is also included being used for the shielding construction for shielding leakage field with non-maintaining air reactor.
