ZM-1型PA级电流测量仪研制

Development of ZM-1 PA Class Current Measuring Instrument

ZM-1型PA级电流测量仪主要用于核电站辐射监测系统电离室的测量维修实用工具。电离室在电站中每隔一个使用循环需要进行预防性维修,维修过程中需要对电离室的工作性能进行确认。ZM-1型PA级电流测量仪可以对电离室的工作电压、电流进行测量以此来判断电离室的工作状态。通过使用ZM-1型PA级电流测量仪能提高现场的工作效率30%,同时可以准确判断电离室的故障点。ZM-1型PA级电流测量仪研制包括通讯模块、测量模块、显示模块、输入模块。当待测设备按照正确方式接至测量仪输入端时,静电计采集其直流电流信号并将其转换为直流电压信号,通过数据计算送显示单元判断被测设备的性能。

ZM-1 PA class current measuring instrument is mainly used for the measurement and maintenance of ionization chamber of radiation monitoring system in nuclear power plant.Preventive maintenance is needed for the ionization chamber every other use cycle in the power plant,the working performance of the ionization chamber needs to be confirmed during the maintenance process.ZM-1 PA class current measuring instrument can measure the working voltage and current of the ionization chamber to judge the working state of the ionization chamber.By using ZM-1 PA class current measuring instrument,the working efficiency of the field can be improved by 30%,and the breakdown point of the ionization chamber can be accurately judged.The development of ZM-1 PA class current measuring instrument includes communication module,measurement module,display module and input module.When the equipment to be tested is connected to the input end of the measuring instrument in the correct way,the electrometer collects its DC current signal and converts it into DC voltage signal,which is sent to the display unit through data calculation to judge the performance of the equipment to be tested.
