JY-16A 等型号的小型多触点继电器,在小型 X线机和其它设备中使用比较广泛。由于继电器触点被电弧烧蚀,使设备不能正常工作。但在多对触点中,由于通过各对触点的电流不相等,损坏较重的仅发生在大电流通过的触点,其余触点很少损坏或无损。所谓充分利用,就是将损坏较重的触点处理后,与无损触点位置互换,使继电器继续工作。这里,要注意的是对于装有熄弧电阻的开关接点,要仔细调 JY-16A and other models of small multi-contact relays are widely used in small X-ray machines and other equipment. Because the relay contacts are ablated by the arc, the equipment does not work properly. However, in a plurality of pairs of contacts, since the currents passing through each pair of contacts are not equal, the heavier damage occurs only at the contacts through which the large current passes, and the remaining contacts are rarely damaged or non-destructive. The so-called full use, is to deal with the heavier damage after contact with the non-destructive contact position, so that the relay continues to work. Here, it should be noted that for switch contacts with arc extinguishing resistors, careful adjustment is required.
