Abstract

The utility model provides a magnetic control reactor of eight post iron cores, eight main iron cores are in one line, the other post iron core of middle six main iron core posts and both sides is connected with upper and lower yoke core respectively, main iron core post is direct seam with the seam of upper and lower yoke core, other post iron core stitches for the juxtaposition with the seam of upper and lower yoke core, main iron core post is echelonment elliptical section, other post iron core is rectangular cross section with upper and lower yoke core yoke, the cross -section of main iron core post is greater than the cross -section of yoke core from top to bottom, the cross -section of other post iron core is the same with the cross -section of upper and lower yoke core, make it to form closed magnetic flow way, constitution control circuit is connected with silicon controlled rectifier and diode to the coil cover on main iron core post. The silicon controlled rectifier triggers respectively in the cycle in mains voltage's a power frequency and switches on, through upper and lower yoke for the control magnetic flow provides the circulation return circuit, make the magnetic saturation of main iron core post. Adjusting the silicon controlled rectifier angle of flow and can changing the big or small of direct current control current and corresponding iron core magnetic saturation, make reactor capacity continuously adjustable, need not provide DC power supply can directly adjust.

Description

A kind of magnet controlled reactor of eight column iron cores

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 eight column iron cores 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, simple eight column iron cores of structure.

The concrete technical scheme solved the problem is:

A kind of magnet controlled reactor of eight column iron cores, it is characterized in that: the centre of eight column iron cores in one line is six main iron core posts 1, two side ends is other column iron core 2, the upper end of main iron core post 1 and upper yoke core 3, be connected for directly stitching between lower end with lower yoke core 4, the upper end of other column iron core 2 and upper yoke core 3, for mitre is connected between lower end with lower yoke core 4, main iron core post 1 is stepped elliptic cross-section, other column iron core 2, upper yoke core 3 and lower yoke core 4 are square-section, the cross section of main iron core post 1 is greater than the cross section of yoke core 3 and lower yoke core 4, the cross section of other column iron core 2 is identical with the cross section of lower yoke core 4 with upper yoke core 3, make it to form closed flux path, six coils 5 of reactor are enclosed within middle six main iron core posts 1 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 uniqueness of the present utility model, make controllable silicon difference triggering and conducting in a power frequency period of supply voltage that main iron core post coil connects, providing flow cycle by upper and lower yoke 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.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details.

A magnet controlled reactor for eight column iron cores, its reactor control structure is identical with conventional reactor.Core structure is eight rod structures, as Fig. 1, shown in Fig. 2, the centre of eight column iron cores in one line is six main iron core posts 1, two side ends is other column iron core 2, the upper end of main iron core post 1 and upper yoke core 3, be connected for directly stitching between lower end with lower yoke core 4, the upper end of other column iron core 2 and upper yoke core 3, for mitre is connected between lower end with lower yoke core 4, main iron core post 1 is stepped elliptic cross-section, other column iron core 2, upper yoke core 3 and lower yoke core 4 are square-section, the cross section of main iron core post 1 is greater than the cross section of yoke core 3 and lower yoke core 4, the cross section of other column iron core 2 is identical with the cross section of lower yoke core 4 with upper yoke core 3, make it to form closed flux path, six coils 5 of reactor are enclosed within middle six main iron core posts 1 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.

Main iron core post in the utility model adopts eight column iron core structures, and six middle main iron core posts are multistage elliptic cross-section, and stepped ellipse, as shown in Figure 3, other column iron core and upper lower yoke core are square-section, as shown in Figure 4.Seam between main iron core post and upper lower yoke core is directly stitch, seam between other column iron core and upper lower yoke core is mitre, the cross section of main iron core post is greater than the cross section of lower yoke core, the cross section of other column iron core is identical with the cross section of upper lower yoke core, make it to form closed flux path, on the one hand meet normal communication magnetic circuit, meet on the other hand and control DC circuit magnetic loop so that make lower yoke core and other column iron core unsaturated.Due to eight column iron core structures of uniqueness of the present utility model, make controllable silicon difference triggering and conducting in a power frequency period of supply voltage that main iron core post coil connects, flow cycle is provided for controlling magnetic flux by upper lower yoke core, make the magnetic saturation of main iron core post, 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.
