摘要
在电力系统中,接地是一个非常重要的问题,接地的质量关系到电气设备和人身的安全.基于TMS320F2812设计了接地电阻双线圈式测试方案,制作了原理样机.此原理样机对多个阻值的环路电阻进行实际测试,测试结果验证了设计方案的正确性,并且原理样机在抑制高频、低频和发射线圈的同频干扰方面具有良好的性能,可以应用到变电站接地电阻的测试当中.
In the power system, grounding is a very the electrical equipment and the safety of person. important issue. The quality of grounding is directly related to The dual-coil grounding resistance test program based on TMS320F2812 was designed, and a prototype was produced. This prototype was applied to test the loop resistances of different values. The result shows the correctness of the test program and that the prototype has a good suppression of the interferences of high frequency harmonic, low-frequency harmonic and the same frequency signal and it is very reliable. It can be used in the detection of grounding resistance of the transformer substation.
