目前,无论国产或进口的X线机,使用时接通电源,停用时切断电源。但一疏忽大意,忘掉关电闸,机器长时间通电,球管灯丝点燃过久,加速老化,或设备损坏,造成大的损失(近期我们地区已有例子)。现介绍一个简便的办法,来帮助人记忆。即使操作者忘掉关机,也可及时加以弥补,使机器电源切断,从而达到保护X线机,延长球管的使用寿命。 At present, regardless of domestic or imported X-ray machines, the power is turned on when in use, and the power is turned off when it is deactivated. However, one carelessness, forgetting to turn off the switch, long-term power on of the machine, bulb filament burning too long, accelerated aging, or equipment damage, resulting in large losses (examples in our area recently). Now introduce a simple way to help people remember. Even if the operator forgets to turn off the power, it can make up for it in time to cut off the power of the machine so as to protect the X-ray machine and extend the service life of the tube.
