(54) ОТКЛОНЯЮЩАЯ СИСТЕМА ДЛЯ ПРИЕМНЫХ ТЕЛЕВИЗИОННЫХ ТРУБОК(54) DIFFERENT SYSTEM FOR RECEIVING TELEVISION PIPES
1one
Изобретение относитс к области телевидени и может примен тьс в качестве магнитной отклон ющей системы дл электроннолучевых трубок в телевизионных приемниках , видеоконтрольных и индикаторных устройствах.The invention relates to the field of television and can be used as a magnetic deflection system for cathode-ray tubes in television receivers, video monitoring and indicator devices.
Известные отклон ющие системы 1 расщир ющейс формы содержат седлообразные строчные и тороидальные кадровые катущки , либо и строчные,и кадровые - седлообразные , которые располагаютс в зазоре между горловиной трубки и сердечником. При этом все типы катушек характеризуютс посто нством значени ампер-витков вдоль продольной оси симметрии системы, так как все слои намотки катущек имеют одинаковую длину.The known diverting systems 1 of the expanding form contain saddle-shaped lowercase and toroidal personnel rolls, or both lowercase and personnel rolls - saddle-shaped, which are located in the gap between the neck of the tube and the core. In this case, all types of coils are characterized by a constant value of ampere turns along the longitudinal axis of symmetry of the system, since all layers of the winding of the coils have the same length.
Недостатком известных систем вл етс их относительна больша материалоемкость при намотке катушек.A disadvantage of the known systems is their relative high consumption of materials during the winding of the coils.
Наиболее близкой по технической сущности вл етс отклон юща система дл приемных телевизионных трубок, содержаща седлообразные катущки и наружный сердечник 2,.The closest to the technical essence is a deflection system for receiving television tubes, comprising saddle-shaped spools and an outer core 2 ,.
Недостатками известной отклон ющей системы вл ютс , во-первых-, сравнительноThe disadvantages of the known deflecting system are, firstly, relatively
низка эффективность отклонени из-за неравномерности распределени магнитного по л вдоль оси симметрии телевизионной трубки и, во-вторых, наличие значительного омического сопротивлени отклон ющих катуJ щек, что вызывает значительные потери мощ ности.low deviation efficiency due to uneven distribution of the magnetic over the field along the axis of symmetry of the television tube and, secondly, the presence of significant ohmic resistance of the deflecting catches, which causes significant power losses.
Целью изобретени вл етс повышение эффективности отклонени и уменьшение расхода медного провода на намотку.The aim of the invention is to increase the efficiency of the deviation and reduce the consumption of copper wire for winding.
Указанна цель достигаетс тем, что на0 ружиый сердечник выполнен в виде трех кольцевых частей, и кажда седлообразна катущка - состо щей из трех слоев, внутренний из которых имеет длину, равную суммарной длине отклон ющей системы, а два последующих сло , соответственно, 0,6-0,8 This goal is achieved by the fact that the outer core is made in the form of three annular parts, and each saddle-shaped spool consists of three layers, the inner of which has a length equal to the total length of the deflecting system, and two subsequent layers, respectively, 0.6. -0,8
15 . и 0,3-0,5 суммарной длины и размещены таким образом, что их задние отогнутые торцовые витки расположены в зазорах между кольцевыми част ми наружного сердечника , а передние торцовые витки совмещены.15 . and 0.3–0.5 of the total length and are placed in such a way that their rear bent face coils are located in the gaps between the annular parts of the outer core, and the front end coils are aligned.
20 Сущность изобретени по сн етс чертежом , где показано продольное сечение отклон ющей системы.20 The invention is illustrated in the drawing, which shows a longitudinal section of a deflecting system.
Устройство состоит из седлообразных трехслойных катушек 1 и составного ферроThe device consists of saddle three-layer coils 1 and composite ferro
