Description

Дл  гашени  дуги в электрических выключател х примен ют гасительные камеры, снабженные электромагнитной системой, создающей магнитное поле, направленное перпендикул рно к плоскости перемещени  электрической дуги.For extinguishing the arc, electric switches use extinguishing chambers equipped with an electromagnetic system that creates a magnetic field, directed perpendicular to the plane of movement of the electric arc.

Предлагаема  камера более соверщенна по сравнению с известными гасительными камерами подобного рода, так как она обеспечивает существенное повыщение эффективности гашени  дуги.The proposed camera is more perfect than the known extinguishing chambers of this kind, as it provides a significant increase in the efficiency of arc extinction.

Дл  этого электромагнитна  система камеры выполнена в виде пр молинейного магнитопровода с трехфазной обмоткой, создающей бегущее магнитное поле.For this, the electromagnetic system of the camera is made in the form of a rectilinear magnetic circuit with a three-phase winding, creating a traveling magnetic field.

На фиг. 1 и 2 изображена принципиальна  схема предлагае.мой камеры в двух проекци х.FIG. Figures 1 and 2 depict a schematic diagram of the proposed camera in two projections.

Действие предлагаемой камеры основано на удлинении дуги с помощью бегущей волны магнитного пол . Бегущее магнитное поле создаетс  трехфазным током, подводимым к обмотке, монтируемой в шихтованном  рме /.The action of the proposed camera is based on the elongation of the arc using a traveling wave of a magnetic field. The running magnetic field is created by a three-phase current supplied to the winding mounted in the laminated frame /.

Электрическа  дуга 2, подобно проводнику с током, увлекаетс  перемещающимс  магнитным полем. Однако свободному ее перемещению преп тствуют специальные ребра 3 из асбестоцемента, огиба  которые дуга удлин етс .Electric arc 2, like a conductor with current, is carried along by a moving magnetic field. However, the special ribs 3 of asbestos cement, the curvature of which the arc is lengthened, prevent its free movement.

Обмотка, заложенна  в пазы  рма }, защищаетс  от воздействи  дуги листом 4 из асбестоцемента.The winding laid in the grooves of the chromium} is protected from the influence of the arc by sheet 4 of asbestos cement.

Скорость гащепи  дуги зависит от скорости перемещени  магнитного пол , которое определ етс  длиной  рма /, частотой подведенного напр жени , числом полюсов распределенной трехфазной обмотки и конструктивным выполнением камеры.The arc speed of the arc depends on the speed of movement of the magnetic field, which is determined by the length of the frame /, the frequency of the applied voltage, the number of poles of the distributed three-phase winding, and the structural design of the chamber.

Предмет изобретени Subject invention

Гасительна  камера с магнитным дутьем дл  электрических выключателей , снабженна  электромагнитиой системой, создающей магиитное поле, направленное перпендикул рно к плоскости перемещени  электрической дуги, отличающа с   тем, что, с целью повышени  эффективности гащени , указанна  электромагнитна  система выполнена в виде пр молинейного магнитопровода с трехфазной обмоткой, создающей бегущее магнитное поле.Extinguishing chamber with magnetic blast for electrical switches, equipped with an electromagnetic system that creates a magnetic field, directed perpendicular to the plane of movement of the electric arc, characterized in that, in order to increase the efficiency of the shielding, the electromagnetic system is made in the form of a straight magnetic circuit with a three-phase winding creating a running magnetic field.
