The invention can meet the requirement of a reactor with high voltage and large capacity, is favorable to the heat radiation of a winding in every reactor body and has the advantages of simple assembly and reliable operation.
Description
Technical field
The invention belongs to the reactor technical field, relate to a kind of radiator structure of reactor.
Background technology
Existing single-phase iron-core reactor all is by single day shaped iron core; The single coil suit; This structure is suitable for certain voltage, product below the constant volume, but after electric pressure, capacity acquire a certain degree (being that 800KV, capacity are the product of 100000kvar like electric pressure), along with the maximization of product; Width, the height dimension of product further increase, and have brought difficulty for the transportation of reactor.In addition, because the insulating part creepage distance of product itself is conditional, be not under certain insulation distance, can allow the unconfined increase of voltage.When the electric pressure of product further raise, the creepage voltage that insulating part bore increased, and can come potential safety hazard to product tape.
Like this, the voltage on acting on iron-core reactor, when capacity acquires a certain degree, because the restriction of transportation and insulating material, single iron core and coil can not satisfy transportation and the insulating requirements of high voltage, products with larger capacity.
Summary of the invention
The inventor has invented a kind of reactor that adopts a plurality of machine body structures to the existing above-mentioned deficiency of single-phase iron-core reactor in the prior art, because this reactor adopts two or more reactor device bodies; Compare with the single-phase iron-core reactor of employing; The clamping that compresses with the iron yoke of stem unshakable in one's determination guarantees more easily, so to noise with vibrate controlled, with the product of same capability; Adopt a plurality of reactor device bodies to mean that the single-column capacity reduces; Therefore the reactor loss is concentrated and is improved, thereby has improved the Temperature Distribution of entire product, has avoided the local hot issue that exists in the device body.
Technical problem to be solved by this invention is that the reactor that is directed against a plurality of device bodies of above-mentioned employing provides a kind of radiator structure.
The solution technical scheme that technical problem of the present invention adopted is that the radiator structure of this reactor includes the radiator that is connected on the reactor oil tank; Said reactor main body comprises the device body that two or more are independent, each reactor device body through its inner coil be linked together.
Radiator can adopt one or more, and each radiator is symmetrically distributed in the one or both sides of fuel tank or all around.
Each reactor device body places in the same fuel tank, and correspondingly, said each radiator all is connected on the said fuel tank.
Preferably, the arrangement mode of each device body can adopt this arrangement mode that the electrode diameter of remotely current potential, and lead-out wire of lead-out wire (lines between two coils) can be dwindled for being arranged in parallel; Or be in-line and arrange, when adopting this arrangement mode in the reactor two device bodies leakage field between two coils interfere with each other little.
The radiator structure of reactor of the present invention is through adopting radiator in the reactor of many devices body; More help the heat radiation of winding in each reactor device body; This radiator structure is particularly useful for 1000kV, the above high voltage of 100000kvar, jumbo reactor product applicable to any a reactor that different electric pressures, capacity requirement are arranged.
Adopt the reactor of many machine body structures to compare on performance with single device body reactor and significantly improve, all favourable to the heat radiation of the control of leakage field, winding, its insulating reliability and transportation aspect can both meet the demands.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
Following embodiment is indefiniteness embodiment of the present invention.
Embodiment 1:
Show that like Fig. 1,2,7 reactor in the present embodiment adopts two device body reactors, it comprises reactor main body 3, oil conservator 4.Reactor main body 3 comprises two independent reactor device bodies, and two device bodies are formed two machine body structures, and two device bodies link together through its inner coil.Two reactor device bodies all place in the reactor oil tank 6, and fuel tank 6 is communicated with oil conservator 4.
As shown in Figure 7, in the present embodiment, be connected with four groups of radiators 5 on the fuel tank 6, radiator 5 is symmetrically distributed in two sides of fuel tank 6.
Shown in Fig. 3-6; In two device body reactors of present embodiment, each device body comprise a day shaped iron core 7 with coil 8, the core limb 10 that to be a plurality of cakes unshakable in one's determination 9 that have a centre bore in the middle of each day shaped iron core overlap with a plurality of air gaps; Core limb 10 a plurality ofly draws tighten on the screw rod by what pass centre bore; Upper and lower and both sides are to be formed by certain thickness core lamination, are clamped by core through screw rod, and coil 8 is sleeved on the core limb 10.
The arrangement mode of two transformer bodies can adopt and be arranged in parallel (like Fig. 3, shown in 4) or in-line arrangement (like Fig. 5, shown in 6).
