New Device for Grounding Resistance Measurement of Grounding Grids along Qinghai-Tibet Railway

摘要

摘要: 为在青藏铁路变电站接地网测量接地电阻时减少所需的人力物力和降低测量难度,提出了新型接地电阻测量装置.用此装置测量时,根据现场土壤结构情况,通过地表电位分布确定出电压极布置位置,并用变频技术避开了工频干扰,保证了测量精度.与传统的大电流法相比,该装置设备容量、引线长度和所需人力分别减少80%,60%和62%,测量结果相差约6%.

Abstract: To reduce the cost in grounding resistance measurement of grounding grids along Qinghai-Tibet railway,a new grounding grid resistance measurement device was designed.When the measurement is conducted with the device,the earth surface voltage distribution is measured first to determine the spot where voltage pole is installed.Frequency conversion technology was used to avoid alternating current disturbances and to get a reasonable measurement precision.Compared with the traditional method,in which a large current is necessary,the capacity,the wiring length and the needed labor of the proposed system are reduced by 80%,60% and 62%,respectively,with a difference in measured resistance being about 6%.
