彩电显像管管座,在电视机电路中起着举足轻重的作用,他的质量好坏直接影响到电视机的图像质量。十几年来市场上用于维修的国产管座质量普遍欠佳,加上电视机工作在潮湿的环境中,空气湿度在电极间易产生电离,特别是彩电的聚焦电压较高时,电离产生的氮氧等负离子是强氧化剂,对聚焦极的金属插件及塑料部件产生腐蚀,产生金属离子,在水分和电场力
TV tube socket, plays a decisive role in the TV circuit, his quality directly affects the quality of the TV image. More than 10 years for the domestic market for the maintenance of the quality of the general poor, coupled with the TV work in humid environment, the air humidity is prone to ionization between the electrodes, especially when the focus of color TV high voltage, ionization Negative ions such as nitrogen and oxygen are strong oxidants that corrode the metal plugs and plastic parts of the focusing electrode and generate metal ions. Under the action of moisture and electric field
