忌频繁开关 有的人在收看电视节目时,偶尔有事要离开片刻,便立即关掉电视机,以为这样做既可节电,又会延长显像管的使用寿命.其实正相反,电视机一开一关,与不关而连续使用10分钟所消耗的电量相差无几.此外,电视机在开关时,其“冲击电流”是正常电流的4.7倍,比日光灯开启时的“冲击电流”要大得多.频繁的大电流冲击,会严重影响电视机显像管的使用寿命.测试表明,电视机每开启一次,显像管的使用寿命就会缩短1～3小时.
Avoid frequently switching some people watch TV shows, occasionally leave something for a moment, they immediately turn off the television, in order to do so can save energy, but also extend the life of the tube. In fact, on the contrary, the TV one Off, and not related to the continuous use of 10 minutes of consumption of electricity consumption is almost the same. In addition, the TV switch, the “impact current” is 4.7 times the normal current, fluorescent light than when the “inrush current” is much larger Frequent high current impact, will seriously affect the life of the TV picture tube test shows that each time the TV is turned on, picture tube life will be shortened 1 to 3 hours.
