Description
Technical field
The utility model relates to reactor technical field, in particular to a kind of six Xiang Qizhu reactors.
Background technique
The three-phase reactor in electrical system applied currently on the market, primary structure are three-phase three-columns, are applied to conventional
Three-phase symmetrical route and be free of zero-sequence component or smaller zero-sequence component when, advantage is that structure is simple, at low cost.But work as three-phase circuit
It is required that working independently or two-way combining system disadvantage is as follows:
1. when three-phase circuit requires to work independently: inductance declines nearly a quarter or more；
2. when two-way combining system: zero-sequence current cannot be run greatly in system, the reason is that since three-phase three-limb structure is used
When in the circuit of three-phase symmetrical, the magnetic flux vector of the stem of three-phase and be zero, but when three-phase system is asymmetric or has zero sequence electric
When stream, 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 working.
Regular situation solution is to replace three-phase three-column with three independent single-phase reactors, and one is further added by when machine
Platform paralleing reactor (15 stems of totally 7 reactors), but that there are disadvantages is as follows for this scheme:
1. 1.5 times big compared with three-phase three-column scheme of volume or more (totally 9 stems)；
2. installation effectiveness and reliability reduce by more than 50 (conducting wire jointing has more one times)；
3. cost is higher by nearly 2 times.
Utility model content
The technical problem to be solved by the utility model is to require to work independently or two-way and machine system for three-phase circuit
The problems of system and a kind of six Xiang Qizhu reactor is provided, in the intermediate stem for increasing a coil, installation
Same reactor of mode is suitable, but function is equivalent to three three column reactors or 6 single-phase reactors add a three-phase equilibrium
Reactor.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of six Xiang Qizhu reactors, connect including six stems with air gap, by six stem upper ends with air gap
The upper yoke come, the lower yoke that connects six stem lower ends with air gap, the upper yoke pass through a pair of of upper clamping piece and several
Upper punching fastening screw clamps, and a pair of of upper clamping piece is connected by several top boards；The lower yoke pass through a pair of of lower clamping piece with
And several lower punching fastening screws clamp, a pair of of lower clamping piece is connected by several footing；The upper clamping piece with it is corresponding under
If being connected between folder by dry drawing screw rod；One coil is installed on each stem with air gap, is set on each coil
It is equipped with outlet row and lower outlet row, which is characterized in that further include the intermediolateral column of an air-gap-free, the intermediolateral column of the air-gap-free is logical
It crosses intermediate folder to connect with the upper yoke, lower yoke, is each provided with three band air gaps in the intermediolateral column two sides of the air-gap-free
Stem, all stems with air gap are parallel to each other with intermediolateral column, and the upper yoke is parallel to each other with lower yoke.
In a preferred embodiment of the utility model, the upper yoke, lower yoke, air-gap-free the width of intermediolateral column be
0.5-1 times of the width of stem with air gap.
In a preferred embodiment of the utility model, the coil is foil coiling or wound coil.
The utility model is mainly used for system three-phase imbalance or provides circuit when having zero-sequence current and the single-phase work of system,
Remain unchanged every sensibility reciprocal.
By actual test, the present invention has the advantage that compared with prior art
1. small in size: more than the more common small one third of three-phase three-column scheme；
2. installation effectiveness is higher by 3 times or more (common solution needs 3 or more independently installed)；
3. at low cost: being 0.5 times of common three-phase three-column scheme；
4. high-efficient: being 1.5 times or more of common three-phase three-column scheme.
