Abstract

Disclosed is a six-post iron core magnetic controlled reactor. The reactor is characterized in that six main iron cores are arranged in a line and connected integrally with an upper yoke iron core and a lower yoke iron core; seams formed by the main iron cores, the upper yoke iron core and the a lower yoke iron core are straight seams; and the main iron cores, the upper yoke iron core and the a lower yoke iron core are stepped multi-stage cross sections. Due to the special iron core structure, controllable silicon connected on coils of a six-post iron core are respectively triggered and conducted during a power frequency cycle of power voltage, and then provide circulating loops for controlling magnetic flux through an upper yoke and a lower yoke, thereby enabling working core posts to be saturated magnetically. By adjusting a controllable silicon conducting angle, magnitude of direct controlling current and corresponding magnetic saturation degree of the iron cores can be changed, thereby enabling the capacity of the reactor to be adjusted continuously. Besides, the structure can adjust the reactor directly without a direct-current power source, thereby being convenient in operation, simplified in devices and comparatively remarkable in economic benefits.

Description

Six column iron core magnet controlled reactors

Technical field

The utility model relates to power equipment in a kind of electrical network, relates to a kind of reactor specifically.

Background technology

Reactor is the electric equipment commonly used that carries out reactive power compensation in the operation of power networks.The adjustable reactor of capacity that uses mostly is magnet controlled reactor at present, this kind magnet controlled reactor uses controllable silicon to control the reactor pondage, it generally is external dc power supply, more complicated, and its voltage-current characteristic of external dc excitation system is significantly non-linear, makes reactor output change bigger.

Summary of the invention

The utility model is at the defective that existing reactor exists, and proposing a kind ofly need not provide DC power supply, and adjusted makes things convenient for, reactor simple in structure.

The concrete technical scheme that addresses the above problem is: a kind of magnet controlled reactor of six column iron cores, it is characterized in that: six main iron core posts adopt in one line, link into an integrated entity with last lower yoke core, main iron core post and last lower yoke core seam are directly to stitch, and last lower yoke core and main iron core post are stepped multistage cross section.

The utility model has the advantages that: because this unique core structure, make the controllable silicon that connects on six column iron core coils triggering and conducting respectively in a power frequency period of supply voltage, thereby for providing flow cycle, the control magnetic flux makes the magnetic saturation of work main iron core post by yoke up and down.By regulating thyristor operating angle, can change the size and the corresponding iron core magnetic saturation of DC control electric current, thereby make that the capacity of reactor can be adjustable continuously.This structure need not provide DC power supply just can directly regulate reactor, and is easy to operate, and equipment is oversimplified, and economic benefit is more remarkable.

Embodiment

A kind of magnet controlled reactor of six column iron cores, its core of reactor structure is six rod structures, as shown in Figure 1 and Figure 2, six main iron core posts 1 adopt in one line, link into an integrated entity with last lower yoke core 2, main iron core post 1 is directly to stitch with last yoke core 2 and lower yoke core 3 seams, and six coils of reactor are enclosed within six respectively. on the main iron core post 1, connect controllable silicon and diode by outside lead in the usual way, constitute control circuit.

The iron core stem stem adopts six column iron cores, main iron core post 1 is multistage circular cross-section, stepped circle, as shown in Figure 3, last lower yoke core is multistage elliptic cross-section, as shown in Figure 4, the section ratio stem stem cross section of yoke is big up and down, satisfy the normal magnetic circuit that exchanges on the one hand, satisfy the control dc circuit magnetic loop on the other hand, so that make the lower yoke core unsaturated.

Claims

1. column iron core magnet controlled reactor is characterized in that: six main iron core posts adopt in one line, link into an integrated entity with last lower yoke core, and main iron core post and last lower yoke core seam be direct the seam, and last lower yoke core and main iron core post are stepped multistage cross section.
