故障现象该机是82年北京医用射线机厂产品。我院安装后工作一直正常,但最近发生以下故障:透视正常;各种技术条件下摄影(包括点片摄影)高压继电器有时不工作,但此时旋转阳极管能转动,球管灯丝亮。分析检修经检查,摄影高压继电器本身无问题。控制电路中与摄影高压继电器有关的线路有以下三部分,如图所示。因为旋转阳极管能启动,说明JC5工作(参看图2),因此J1_(2-)
Phenomenon This machine is a product of the 82-year medical ray machine factory in Beijing. After the installation of our hospital has been working normally, but the following failures occurred recently: Perspective normal; under various technical conditions, photography (including spot photography) high voltage relay sometimes does not work, but at this time the rotating anode tube can rotate, the bulb light. Analytical inspections were checked and there was no problem with the high-voltage relay itself. The circuit in the control circuit that is associated with the photographic high voltage relay has the following three parts, as shown in the figure. Because the rotary anode tube can start, it shows that JC5 works (see Figure 2), so J1_(2-)
