摘要
对改装后的电表进行校准时控制电路有2种选择:制流式和分压式。究竟应该选择哪一种,各种教材和资料均没有明确说明,为了解决这一问题,在多年教学经验的基础上,分析总结控制电路的性能和特点,并结合实验室实际条件,得出改装后的电表校准时控制电路的选择及安排方法。
There are two ways of control circuits when calibrating refitted ammeters： one is flow-circuit system, and the other is pressure circuit. Which one is better, there is no specific parlance in all kinds of teaching materials and data, so the students generally don＇t know how to do. To solve the problem, on the base of years teach- ing experiment, the capability and characteristic of control circuits are discussed, and according to the real condition of laboratory, the conntermeasure is provided.
