35kV及其以下电力电缆导体连接金具电阻测试设备设计与应用

GB/T 9327-2008规定了国内用于35kV电力电缆导体的压接式、机械式连接金具相关试验方法和要求,其中关于连接金具电阻测量给出了很高的要求.本文根据标准所提出的间接测量的方式,使用"欧姆定律"原理,利用stm32作为嵌入式平台设计制作了全自动连接金具电阻测量装置,并与传统QJ36电桥进行了测量比对.

Design and application of resistance testing equipment for 35kV and below power cable conductor connector

GB/T 9327-2008 provides the relevant test methods and requirements for the compression type and mechanical connection fittings used in 35kV power cable conductors in china. According to the standard of indirect measurement, the use of "Ohm's law" principle, the use of STM32 as the embedded platform is designed for automatic connection fittings resistance measuring device, and measuring the comparison with the traditional QJ36 bridge.
