摘要
Abstract
For DC leakage current measuring sensor in the existing substation DC system needs field wiring and lack of flexibility,a new DC leakage current measuring terminal was developed based on the on-chip resources of CC2530 IEEE 802.15.4/ZigBee,and the measuring accuracy and reliability of the communication test was carried out.The developed measuring terminal is made up of a current sensing module,a main control unit module and a power source module,where the current sensing module is designed based on the through core type small current sensor work on Holler-magnetic balance principle,the main control module is based on CC2530 chip to realize measuring signal digitization,transmission and power management.The test results show that the measuring range of developed measurement terminal is 0~20 mA and the resolution is 50 μA,the indoor environment effective communication distance up to 50 m.关键词
