Description

A kind of magnet controlled reactor of conjugation-type iron core

Technical field

The utility model relates to the reactor used in a kind of power equipment of electrical network, relates to a kind of magnet controlled reactor of conjugation-type iron core specifically.

Background technology

Reactor is the conventional electric equipment carrying out reactive power compensation in operation of power networks.The reactor of current use mostly is magnet controlled reactor, this kind of magnet controlled reactor uses controllable silicon to control reactor pondage, is generally external dc power supply, more complicated, and its voltage-current characteristic of external dc excitation system is in significantly non-linear, makes reactor exporting change larger.

Summary of the invention

The defect that the utility model exists for existing reactor, proposes one and need not provide DC power supply, operate magnet controlled reactor that is easy to adjust, the simple conjugation-type iron core of structure.

The concrete technical scheme solved the problem is:

A kind of magnet controlled reactor of conjugation-type iron core, it is characterized in that: the iron core of conjugation-type is provided with three upper main iron core posts 1 and three lower main iron core posts 2, two side ends is other column iron core 4, upper main iron core post 1 and lower main iron core post 2 share a middle yoke core 3, the upper end of upper main iron core post 1 and upper yoke core 5, between lower end and middle yoke core 3, the upper end of lower main iron core post 2 and middle yoke core 3, between lower end and lower yoke core 6, the upper end of other column iron core 4 and upper yoke core 5, between lower end and lower yoke core 6, the middle-end of other column iron core 4 is connected with being directly to stitch between middle yoke core 3, upper main iron core post 1 and lower main iron core post 2 are stepped circular cross-section, middle yoke core 3, other column iron core 4, upper yoke core 5 and lower yoke core 6 are square-section, the cross section of upper main iron core post 1 and lower main iron core post 2 is greater than the cross section of yoke core 5 and lower yoke core 6, the cross section of other column iron core 4 is identical with the cross section of lower yoke core 6 with upper yoke core 5 and be 1/2nd of the cross section of middle yoke core 3, make it to form closed flux path, six coils 7 of reactor are enclosed within three upper main iron core posts 1 and on three lower main iron core posts 2 respectively, control circuit is connected and composed by lead-in wire and the controllable silicon in the external equipment excitation unit of reactor and diode.

the utility model has the advantages that:due to the core structure of the conjugation-type of the utility model uniqueness, make controllable silicon difference triggering and conducting in a power frequency period of supply voltage that main iron core post coil connects, thering is provided flow cycle by upper lower yoke core for controlling magnetic flux, making the magnetic saturation of work stem stem.By regulating thyristor operating angle, the size of DC control current and corresponding iron core magnetic saturation can be changed, thus make the capacity of reactor can continuously adjustabe.This structure need not provide DC power supply just directly can regulate reactor, easy to operate, and equipment is simplified, and economic benefits comparison is remarkable.
