彩电偏转线圈位于彩管锥体与管颈的连接处,它由行偏转线圈、场偏转线圈两大部分构成。其作用是实现电子束在荧光屏上的行、场扫描,从而形成稳定正常的光栅,一旦偏转线圈损坏或替代型号不对,将会出现无光栅或光栅失真故障。偏转线圈从外型上看可分为配合显像管粗管径、细管径使用的两大类。从场偏转线圈的阻抗大小又可分为有高阻抗和低阻抗两大类。由于彩色电视机行输出电路均相同或相似,故行偏转线圈几乎都一样,其直流电阻为零点几到几欧姆,而场偏转线圈则不同,它是因场输出电路不同而各异。若场输出级采用
Color TV deflection coil is located in the color tube cone and the neck of the junction, which consists of line deflection coil, field deflection coil composed of two parts. Its role is to achieve electron beam in the screen of the screen, field scanning, to form a stable normal grating, once the deflection coil damage or alternative model is wrong, there will be no grating or grating distortion failure. Deflection coil from the appearance point of view can be divided into with the tube diameter, the use of thin tube diameter of two categories. From the field deflection coil impedance size can be divided into high impedance and low impedance two categories. Because the color TV line output circuit are the same or similar, so the line deflection coils are almost the same, the DC resistance of zero to a few ohms, while the field deflection coil is different, it is due to the field output circuit varies. If the field output stage
