Description
Technical field
The utility model is related to transformer technology field, especially a kind of three-phase integrated hollow reactance with conjugated structure
Device.
Background technology
With the development of power industry, various protection equipment and technologies are greatly improved, because short circuit is drawn in transformer fault
The failure success chief component risen.To improve transformer anti-short circuit capability, power industry employs many kinds of measures and improvement
Method, wherein most important measure is to reduce the short circuit current flow for flowing through transformer, one kind is to improve transformation using current-limiting reactor
Device impedance, a kind of is the short circuit current flow by adding current-limiting reactor limiting transformer.The common practice of previous reactor is iron core
It is designed to frame structure, magnetic flux passes through upper yoke, other column, lower yoke, coil, forming circuit.Such mode is of high cost, size is big, system
Make complicated.
Utility model content
The technical problems to be solved in the utility model is：A kind of three-phase integrated hollow reactance with conjugated structure is provided
Device, to solve the above problems.
Technical solution is used by the utility model solves its technical problem：It is a kind of three-phase integrated with conjugated structure
Air reactor including air core coil and is arranged on the upper yoke and lower yoke at air core coil both ends, and the upper yoke leads to
Screw rod is crossed to be connected with upper clamping piece, top beam；The lower yoke is connected by screw rod with lower clamping piece, feet；Upper and lower folder
Part to form frame and the coil that is fixed and clamped by the way that screw rod is drawn to be connected again；The air core coil does not have stem and other column；Three
Phase magnetic flux collects and cancels out each other respectively in upper and lower iron yoke.
Further, upper yoke and lower yoke described in the utility model are that three-phase shares, by silicon steel sheet group into.
It further says, the length and width of upper yoke and lower yoke described in the utility model is all higher than beyond hollow
The outer diameter of coil.So magnetic flux can be made more to be introduced directly into upper and lower iron yoke, so as to which three-phase is cancelled out each other, reduce magnetic flux
It overflows.
The beneficial effects of the utility model are that solve defect present in background technology, by three-phase coil, Double layer iron
The compositions such as yoke, folder from top to bottom, feet；Three-phase coil is placed side by side, and upper and lower side sets iron yoke, and iron yoke shares for three-phase, without side
Column；Three-phase magnetic flux collects in iron yoke cancels out each other, and magnetic flux is avoided to be spilled over to reactor peripheral structural member and generates vortex or circulation,
Loss is caused to increase setting and hot-spot occurs；Equipment investment is not required to, is made simple, of low cost, safe and reliable.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model；
Fig. 2 is the side view of the utility model；
In figure：1st, screw rod；2nd, upper clamping piece；3rd, coil；4th, screw rod is drawn；5th, lower clamping piece；6th, top beam；7th, upper yoke；8th, lower iron

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing and preferred embodiment.These attached drawings are letter
The schematic diagram of change, only illustrates the basic structure of the utility model in a schematic way, thus its only show it is related with the utility model
Composition.
A kind of three-phase integrated air reactor with conjugated structure as shown in Figs. 1-2 is three-phase reactor, without the heart
Column and other column, only upper and lower iron yoke.Three-phase magnetic flux collects respectively in upper and lower iron yoke, and three-phase is finally cancelled out each other.
8 lower yoke of Fig. 1 middle terms shares for three-phase, by silicon steel sheet group into passing through 1 screw rod of item and 5 lower clamping piece of item, 9 feet of item
It is connected, is placed in lower part.8 lower yoke tops of item set supporting plate and core insulation, and 3 coil of item, coil inside are being placed in top
Without stem, 3 coil top of item sets core insulation and pressing plate.7 upper yokes are similarly three-phase and share, and have silicon steel sheet group into leading to
It crosses 1 screw rod of item to be connected with 2 upper clamping piece of item, 6 top beam of item, is then placed on three-phase coil pressing plate top.Screw rod is drawn by item 4
5 lower clamping piece of 2 upper clamping piece of item and item is connected, so as to be connected, forms air reactor.Upper and lower iron yoke is in length and width side
To being both needed to beyond coil outer diameter, magnetic flux is made more to be introduced directly into iron yoke up and down so as to which three-phase is cancelled out each other, magnetic flux is reduced and overflows
Go out.Iron yoke height depends on magnetic flux size, and preventing in iron yoke that magnetic flux is excessive causes saturation during short circuit or cause excessive vibration.
Simply specific embodiment of the present utility model described in description above, various illustrations are not to this practicality
New substantive content is construed as limiting, and person of an ordinary skill in the technical field can be to former institute after specification has been read
The specific embodiment stated is made an amendment or is deformed, without departing from the spirit and scope of utility model.
