农村基层医院每到农忙季节,往往因用电量的骤然增加,出现电力不足而停电的现象。我院放射科使用的是两台200毫安x线机,按机器性能要求必须有25瓩的发电机供电才能满足使用。可是我们仅有一台4瓩供照明还感到不足的小发电机,经按装平衡负载革新部分线路后,用4瓩的小发电机解决了200毫安x线机的用电问题(电原理见附图)。具体方法如下:在电原输入回路中加入两个电器平衡负载。负载W_1与x线机的自耦变压器并联。负载W_2与高压发生器并联。两个平衡负载均受电闸S_2控制。用外来电透照时把S_2闸刀拉开;用自发电透照时合上电闸S_2,这时电能即分别加在W_1与W_2上。当按动开机按扭时由CTO
In the countryside during the busy season, the grass-roots hospitals often suffer from blackouts because of the sudden increase in electricity consumption. The radiology department in our hospital uses two 200 mA X-ray machines. According to the machine performance requirements, there must be 25 发电机 generators to supply power. However, we have only one small generator that is still inadequate for lighting. After installing some circuits by balancing the load, we solved the problem of power consumption of the 200-millimeter X-ray machine with a small 4-in. generator. (See Figure). The specific method is as follows: Two electric balance loads are added in the electro-acoustic input loop. The load W_1 is connected in parallel with the autotransformer of the x-ray machine. The load W2 is connected in parallel with the high voltage generator. Both balanced loads are controlled by switch S_2. The S_2 knife is pulled open when the incoming call is transilluminated; when the self-generating transillumination is turned on, the switch S_2 is closed and the power is added to W_1 and W_2.
