CN202495321U - A magnetic control electric reactor with a six-column oblique-angle circular iron core - Google Patents

Abstract

The utility model provides a magnetic control electric reactor with a six-column oblique-angle circular iron core. Six main iron core columns are lined up and connected with upper and lower iron yoke iron cores into a whole; the junctures between the main iron core columns and the upper and lower iron yoke iron cores are oblique junctures; and the upper and lower iron yoke iron cores and the main iron core columns are in the shape of multi-stage steps and have circular sections. The unique iron core structure enables silicon controller rectifiers connected to coils of the magnetic-control electric reactor with the six-column oblique-angle circular iron core to be triggered and turned on separately in a period of supply voltage, so that a circulation return circuit can be provided by upper and lower iron yokes for controlling magnetic flow and thus magnetic saturation of the working main iron core columns is realized. Through adjustment of the turn-on angle of the silicon controller rectifiers, the magnitude of direct current control current and the corresponding magnetic saturation of the iron cores can be changed, so that the capacity of the electric reactor can be adjusted continuously. With such a structure, the electric reactor can be adjusted directly without the supply of direct current supply, thereby being characterized by easy operation, simplification of equipment and relatively significant economical benefit.

Description

The circular magnet controlled reactor unshakable in one's determination in a kind of six post oblique angles

Technical field

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

Background technology

Reactor is the electric equipment commonly used that carries out reactive power compensation in the operation of power networks.Mostly the adjustable reactor of capacity that uses at present is magnet controlled reactor; This reactor uses controllable silicon to control the reactor pondage; Generally be external dc power supply, and its voltage-current characteristic of external dc excitation system is significantly non-linear, makes reactor output change bigger.

The utility model content

The utility model is to 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.

Technical scheme

The utility model solves the technical scheme that its technical problem adopted: the circular magnet controlled reactor unshakable in one's determination in a kind of six post oblique angles; It is characterized in that: six main core stems adopt in one line; Link into an integrated entity with the iron yoke heart up and down; The main core stem is a mitre with iron yoke heart seam up and down, and the iron yoke heart and main core stem are stepped multistage cross section up and down, and the cross section is a circle.

The beneficial effect of the utility model

Because this unique core construction; Make the controllable silicon that connects on the coil of the circular magnet controlled reactor unshakable in one's determination in six post oblique angles triggering and conducting respectively in the one-period of supply voltage; Thereby for the control magnetic flux provides flow cycle, make the magnetic saturation of work main core stem through last lower yoke.Through regulating thyristor operating angle, can change the size and the corresponding magnetic saturation unshakable in one's determination 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

The circular magnet controlled reactor unshakable in one's determination in a kind of six post oblique angles, its iron core of electric reactor structure is six rod structures, shown in Fig. 1.Six main core stems 1 adopt in one line, link into an integrated entity with the iron yoke heart up and down, and main core stem 1 is a mitre with upper yoke unshakable in one's determination 2 and lower yoke 3 seams unshakable in one's determination.Six coils of reactor are enclosed within respectively on six main core stems, press usual manner and connect controllable silicon and diode through outside lead, constitute control circuit.

Stem unshakable in one's determination adopts six posts unshakable in one's determination, and the main core stem is multistage stepped, and the cross section is circular, as shown in Figure 3.The iron yoke heart is multistage stepped up and down, and the cross section level is circular, as shown in Figure 4.The cross section of last lower yoke is bigger than the cross section of stem unshakable in one's determination, satisfies the normal magnetic circuit that exchanges on the one hand, satisfies the DC loop of control on the other hand, and the iron yoke heart is unsaturated up and down so that make.
