Abstract

A magnetically controlled reactor having a six-climb elliptical-section core and a right-angle joint seam adopts six primary core climbs side by side and connected with upper and lower yoke cores to form an integral body. Joint seams between the primary core climbs and the upper and lower yoke cores are right-angle ones. The upper and lower yoke cores and the primary core climbs form a multistage stepped section, which is elliptical. Due to the special core structure, silicon controlled rectifiers connected on coils of the magnetically controlled reactor are triggered and conducted in a power supply voltage period, respectively, thus, a return circuit is provided for a control magnetic flux by upper and lower yokes to make the operating primary core climb magnetically saturated. By regulating a conduction angle of the silicon controlled rectifier, a value of a control direct current and corresponding core magnetic saturation can be changed, so as to realize continuous regulation of the magnetically controlled reactor capacitance. Such structure can directly regulate the magnetically controlled reactor without using a direct current power source, with convenient operation, simple equipment and significant economic benefit.

Description

The oval magnet controlled reactor unshakable in one's determination in a kind of six post right 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 oval magnet controlled reactor unshakable in one's determination in a kind of six post right angles; It is characterized in that: six main core posts are in one line; Link into an integrated entity with last lower yoke; Main core post and iron yoke heart seam up and down be direct seam, and the iron yoke heart and main core post are stepped multistage cross section up and down, and the cross section is an ellipse.

The beneficial effect of the utility model

Because this unique core construction; Make the controllable silicon that connects on the coil of the oval magnet controlled reactor unshakable in one's determination in six post right 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 post 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.
