Description

标准电感箱 技术领域
本发明涉及一种计量或校准领域，特别涉及一种传递电感参数的标准量具。
背景技术
在计量或校准领域，标准电感箱(器)是为了保证电感参数单位量值的一致而特制的电感量具，它是在交流参数测量中，作为电感参数传递的标准量具。
在电感参数计量中，国内外生产的标准电感箱一般为十进制电感箱，最宽范围的电感箱是六盘十进制电感箱，它是从1μH～1H，共有60个标准点输出。但其不足之处是量程窄、体积大，重量重，不能满足整个量程的要求，也不便于运输和到生产现场进行工作。从发展和今后需求来看，现有的1μH～1H范围已不能满足电感参数的量传和校准需求，需要设计更宽范围的标准电感箱，如范围为：1μH～500H。
标准电感箱主要是由以下部分构成：标准电感器、转换开关、输出接口、机箱等组成。标准电感器可分为实物电感器和模拟(无源)电感器，较稳定的实物电感器一般是线绕式电感器，电感量为1μH---1H，最大的可达到10H，但是其体积太大，重量重，工作不方便。模拟电感器一般为T型网络串联等效式电感器，电感量可以达到100mH---10000H。同时需要指出，目前的模拟电感器一般均为单值的模拟电感器。现有的电感箱是用实物电感器做成的，采用十进制方式，范围是从1μH---1H。为了满足RLC数字电桥中电感量的范围，亟待推出一种宽量程标准电感箱。
