SHIMADZUHD150G -12X线机是一台1000mA、最短曝光时间可达到3/1000秒、电路具有预磁功能 (防止高压变压器铁芯偏磁 ,主要用于快速摄影 )、可进行每秒15桢快速摄影的工频机。其曝光采用可控硅控制方式。在机器使用过程中曾出现一例曝光时异常声响故障 ,现报告如下 :故障现象机器
SHIMADZUHD150G -12X line machine is a 1000mA, the shortest exposure time can reach 3/1000 seconds, the circuit has a pre-magnetic function (to prevent high-voltage transformer core bias, mainly used for fast photography), can perform 15 fast photography per second Frequency machine. Its exposure is controlled by silicon controlled. In the process of using the machine, there has been an abnormal sound failure during exposure. The report is as follows: Failure phenomenon machine
