Description
Technical field
It the utility model is related to reactor technical field, and in particular to a kind of air reactor.
Background technology
Reactor, it is the inductive High-Voltage Electrical Appliances for being used for limiting short-circuit current, reactive-load compensation etc. in power system.Reactance
Device is also inductor, and its essence is exactly an inductance element, and inductance value is provided on electric circuit.May compared to iron-core reactor
High current occur causes saturation unshakable in one's determination to cause inductance value changes, and air reactor inductance value is only with appearance and size, the number of turn and being connected
Mode is relevant, and in the case of these parameter constants, inductance value is a constant, unrelated with led to electric current therefore hollow
The linearity of reactor is preferable, has wider use occasion.
In general air reactor is single coil winding construction, and each coil is coiled into by the circle aluminum conductor of Multi-layer Parallel,
Form a winding wire bag.The inductance value that the air reactor provides is single.Air reactor is mainly using leaching asphalt mixtures modified by epoxy resin
Fat organdy coordinates curing agent solidification coil, and star arm banding fixed is in coil upper and lower side, but conventional hollow reactor at present
There is the common fault that noise is larger, and the product cracking that happens occasionally, product partial discharge problem, the qualification rate of product is reduced, influences to produce
The stability of product scene operation.
The content of the invention
The purpose of this utility model is to provide the air reactor of a kind of low noise, cracking resistance.
In order to realize the above object the technical scheme of the utility model air reactor is as follows：
Air reactor, including coil windings, arm, coil windings pour into one with arm by flexibilized epoxies
The reactor body of individual monoblock type, by cast formed with radiating air flue in the reactor body.
The radiating air flue has multiple, formation honeycomb fashion air flue.
Reactor body is tubular structure, and the radiating air flue is axially extending along reactor body.
The arm includes upper boom portion and lower arm, and upper boom portion and lower arm are star arm.
The coil windings are parallel using single or more insulation aluminum conductor and around and each layer conductor is in parallel.
Aluminum conductor periphery described in every layer is provided with DMD insulating barriers.
The beneficial effects of the utility model：The utility model pours into a mould coil windings with arm by flexibilized epoxies
Into the reactor body of a monoblock type, died down in the oscillation phenomenon of reactor operation coil winding, reach effective noise reduction
Purpose.Totally enclosed coil also has the advantages of reliable insulation, cracking resistance.By pouring into a mould formed with heat transmission gas in reactor body
Road, solve the heat dissipation problem of totally-enclosed coil, ensure the running temperature of reactor, alleviate insulation ag(e)ing.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model air reactor；
Fig. 2 is Fig. 1 top view；
Fig. 3 is air reactor loop construction schematic diagram；
Fig. 4 is air reactor coil electric schematic diagram.
Embodiment
The embodiment of the utility model air reactor：As shown in Fig. 1 ~ 3, including coil windings 2, arm, supports insulative
Son, arm include upper boom portion and lower arm 10, and upper boom portion and lower arm are aluminium alloy star arm.Coil windings are led to arm
Cross the reactor body that flexibilized epoxies pour into a monoblock type.Supporting insulator 4 is supported under reactor body
Side, it is DMC supporting insulators.
The selection of the size and wire gauge of coil height and outer warp, all has considerable influence to inductance.With the meter of correlation
Calculation machine auxiliary software chooses wire gauge and reasonable control coil height, encapsulating internal-and external diameter.Coil is exhausted using section very little
Edge aluminum conductor 12 is single parallel and around, each layer conductor parallel relationship, can also use certainly more it is parallel and around.Entered using computer
Row optimization design, ensure the current balance type between each encapsulating wire, effectively reduce the eddy-current loss in harmonic wave lower wire.Per layer conductor
, added with multilayer DMD insulating barriers, play a part of increasing turn-to-turn insulation according to design requirement in periphery.The encapsulating insulation 13 of coil uses
The mode of 1.2mm grids and multilayer DMD parcels, ensures insulating requirements.
By cast formed with radiating air flue 8 in reactor body.Reactor body is tubular structure, radiating air flue edge electricity
Anti- device body is axially extending.Radiating air flue has multiple, formation honeycomb fashion air flue, free convection cooling, perfect heat-dissipating.Specifically
Ground, during integrated poured, it is provided with multiple POM plastic rods 9 between encapsulating, after casting complete, plastic rod of dismantling, just forms honeybee
Socket air flue.By honeycomb fashion air flue, multi-layer heat dissipation face is formed, the running temperature of effective guarantee reactor, alleviates insulation ag(e)ing；
It is alternate or be sufficiently close to the thermal coefficient of expansion of insulating barrier and winding wire, there is superior shock resistance, resisting temperature to become during operation
Change and cracking resistance.Binding strap 14 is also wound with encapsulating, improves stability.
Upper boom portion and lower arm are separately positioned on the upper and lower end of coil windings, provide busbar disengaging wiring position respectively, stretch
The part for going out coil forms inlet wire arm 1, line-outgoing arm 3, for in-site installation into circuit.The conductor in parallel of each coil inside confluxes
Onto upper and lower arm, upper boom portion and lower arm are satisfied by current-carrying requirement.Pass through the integrated poured of arm and coil so that operation
The oscillation phenomenon of coil dies down, and reaches the purpose of effective noise reduction.
In the present embodiment, the epoxy resin of cast uses diglycidyl ether type flexibilized epoxies, pliability epoxy
Resin component is prior art.This type resin has good compatibility, and by the regulation to copolymerization ratios, reaches different
Pliability.
The downside of DMC supporting insulators 4 also supports raises seat 5 provided with fiberglass, and fiberglass rise seat 5 lower end is provided with ground connection
