为方便生产,最近我热电厂为值班长配备了BT-898型无绳电话。在锅炉热控室使用中偶然发现,它对某些数显仪表干扰极强。如锅炉房监测主汽温度的XSZ-102型数字显示仪,当此表附近使用无绳电话时,主汽温度指示由正常的445℃逐渐升至满程800℃。手机发出的射频干扰竟如此之大,难怪规定在飞机上禁止使用移动电话手持机。
For the convenience of production, my thermal power plant recently equipped the duty monitor with a BT-898 type cordless telephone. Occasionally found in the use of the boiler thermal control room, it has a strong interference on some digital instruments. Such as the boiler room monitoring main steam temperature XSZ-102 digital display, when the table near the use of cordless phones, the main steam temperature indicator from the normal 445 ℃ gradually increased to full range 800 ℃. The radio frequency interference emitted by mobile phones is so large that it is no wonder that it is forbidden to use mobile phone handsets on planes.
