Description
Technical field
The utility model is related to reactor technical field, more particularly to a kind of modified form reactor.
Background technology
Three-phase reactor in the electrical system applied currently on the market, primary structure are three-phase three-column, natural wind cold junction
Structure.Advantage be it is simple in structure, it is at low cost, due to three-phase three-limb structure be used in three-phase symmetrical circuit in when, the stem of three-phase
Magnetic flux vector and be zero, but cannot be run when zero-sequence current is big in system, be because three-phase system is asymmetric or have zero
When sequence electric current, it can allow the magnetic flux of stem is excessively high to cause magnetic saturation, in turn resulting in the rising of sensibility reciprocal decline temperature prevents system from work
Make.Conventional solution is to replace three-phase three-column scheme with three independent single-phase reactors, but this scheme is deposited at present
It is as follows in disadvantage：
1. volume compared with the big one third of three-phase three-column scheme more than.
2. installation effectiveness reduces by more than 50.
3. cost is higher by one third or more.
Utility model content
The purpose of this utility model is provided a kind of with special for the problems of existing three-phase reactor
Magnetic structure makes product that can be operated in three-phase symmetrical system, can also be operated in the system of asymmetrical three-phase, may be used also
With the modified form reactor being operated in single-phase or two-phase system.
To achieve the goals above, technical solution used by the utility model is as follows：
A kind of modified form reactor, including upper yoke, lower yoke and spacing side by side setting the upper yoke, lower yoke it
Between tri-phase iron core column, be respectively arranged with three-phase coil on the tri-phase iron core column, the upper end per phase coil be respectively arranged with into,
Outlet row, the upper yoke are locked by upper clamping piece and upper punching fastening screw, and the lower yoke is tight by footing and lower punching
Gu screw rod is locked, which is characterized in that further include two intermediate return yokes, two intermediate return yokes are separately positioned on adjacent in three-phase coil
Between two coils, the upper and lower end of two intermediate return yokes forms magnetic circuit and is connected with the upper yoke, lower yoke respectively.
In a preferred embodiment of the utility model, the section of the intermediate return yoke of the upper yoke, lower yoke and two
Product is equal, and the sectional area per phase iron core column is the sectional area of the sectional area of upper yoke, the sectional area of lower yoke, two intermediate return yokes
1.1-2 times.
In a preferred embodiment of the utility model, it is both provided with air gap per phase iron core column, the air gap is by insulating
Plate is formed.
In a preferred embodiment of the utility model, silicon steel or amorphous material or other iron are all made of per phase iron core column
Powder core is made.
In a preferred embodiment of the utility model, the upper yoke, lower yoke, two intermediate return yokes are all made of silicon
Steel or amorphous material are made.
As a result of technical solution as above, the utility model is used for system three-phase not by the way that two intermediate return yokes are arranged
Circuit is provided when balancing or have zero-sequence current and the single-phase work of system, every sensibility reciprocal is made to remain unchanged.
By actual test, the utility model has following advantages compared with prior art：
1. operating efficiency improves 2 times or more (comparing three single-phase reactors).
2. volume and weight reduce one third or more.
