摘要
利用高导电率导体将地面不带电的导电体相互连接,构成多环路的三维等电位接地网,并与主接地网在适当的位置连通,构成全站的接地系统。设备通过该接地系统可就近实现无引线或短引线接地,降低了传导电流产生的传导性干扰和地电位差干扰,从而进一步降低接地阻抗的效能。通过以上措施可达到消除或降低回路耦合干扰的目的。
The uncharged conductors on the ground are connected to each other by high conductiv-ity conductors to form a three-dimensional multi-loop equipotential ground network. The network isconnected with the main grounding network on proper points, which constitutes the grounding sys-tem of the whole substation. The equipments can conveniently implement lead-free or lead shortgrounding through the grounding system, which reduces conducted interference and ground poten-tial difference interference caused by the conduction current, and further reduces the effectivenessof the grounding impedance. These measures can eliminate or reduce the coupling loop interference.
