The two bodies are arranged in parallel or in a shape of a horizontal line. The two-body structure of the utility model can meet the requirements of high-voltage and high-capacity reactors and has easy assembly, small magnetic flux leakage loss and reliable operation.
Description
Technical field
The utility model belongs to the reactor technical field, relates to a kind of two machine body structures of reactor.
Background technology
Existing single-phase iron-core reactor all is by single day shaped iron core device body, 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 as electric pressure), maximization along with 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 bring potential safety hazard to product.
The utility model content
Technical problem to be solved in the utility model is at the existing above-mentioned deficiency of reactor list machine body structure in the prior art, and two machine body structures of the reactor that a kind of assembling is simple relatively, magnetic loss is little and reliable are provided.
The technical scheme that solution the utility model technical problem is adopted is that two machine body structures of this reactor comprise reactor device body, and wherein, described reactor device body comprises two independent device bodies, and two device bodies are linked together by its inner coil.
The arrangement mode of two device bodies 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.
Two independent device bodies respectively comprise day shaped iron core, and day shaped iron core middle part is a plurality of cake unshakable in one's determination of centre bore and core limbs that a plurality of air gap overlaps and forms of having.
Described reactor two device bodies all place in the same reactor oil tank, because the voltage difference that is acted under the operating voltage, insulation distance can be different, therefore the size of two device bodies can be small one and large one, at two devices during as cascaded structure, as the case may be, the voltage capacity of first device body can be 30-70%, and then the voltage capacity of second device body is 70-30%.Certainly, the size of two device bodies also can be for identical.
The coil of two device body inside is linked together and can passes through coupled in series, also can be by parallel connection.Promptly the connected mode of two coils can also can be parallel connection for series connection.
The coil of two device body inside by be coupled together in series can be in the first device body coil promptly an end of first coil be the end of incoming cables, coil in the other end of first coil and the second a device body i.e. end of second coil is connected, the other end of second coil is a leading-out terminal, forms coupled in series; Series connection also can be that first coil and second coil adopt the middle part inlet wire to be connected in series, promptly first coil adopts at the middle part of coil inlet wire, its both ends outlet and back in parallel are as the inlet wire of second coil, second coil adopts at the middle part of coil inlet wire, outlet after its both ends parallel connection is connected with the middle part inlet wire of second coil after the first coil both ends parallel connection.
When two coil series connection in the utility model two device bodies, satisfying under the prerequisite of shipping height, the coil arrangement hop count of two coils increases than total hop count of single-column coil, total coil height increases, coil under operating voltage is increased greatly along the creepage distance of face, two coils bear operating voltage jointly, have guaranteed the reliability of the reactor product insulation under the operating voltage.
The coil of two device bodies by parallel connection can be together: the end winding parallel connection, and promptly an end of two coils of two device bodies is connected in parallel as the end of incoming cables and does the end of incoming cables, and the other end of two coils is connected in parallel as leading-out terminal and makes leading-out terminal; Parallel connection also can be together: the coil in the first device body is that the coil in first coil and the second device body is that second coil all adopts the middle part inlet wire, and the end of incoming cables, middle part is connected in parallel, two coils in parallel again as leading-out terminal after two ends are connected in parallel up and down, promptly first coil adopts at the middle part of coil inlet wire, its upper and lower end parts outlet and parallel connection, second coil adopts at the middle part of coil inlet wire, its upper and lower end parts outlet and parallel connection, first coil is in parallel with the end of incoming cables, middle part of second coil, two coils, and the both ends parallel connection of the first coil both ends and second coil is as leading-out terminal.
Satisfying the mode that can adopt parallel connection under transportation and the electric property situation, when adopting the mode of middle part inlet wire, less demanding to the insulation level of coil end.
Certainly, the connected mode of the utility model coil is not limited to above-mentioned four kinds of connected modes.
The utility model is owing to adopted two machine body structures, the clamping that compresses with the iron yoke of the stem of independent iron core is guaranteed easily, and then noise and vibration be under control, adopting the reactor loss of single device body to concentrate than same capability product simultaneously is improved, improve the Temperature Distribution of entire product, avoided the local hot issue that exists in the device body.
Because the utility model reactor reduces the single-column capacity, this pair of machine body structure is all favourable to the heat radiation of the control of leakage field, winding, therefore applicable to any a reactor that different electric pressures, capacity requirement are arranged, for the product of 1000kV, 100000kvar, its insulating reliability and transportation aspect can both meet the demands.
