台湾嘉仕KRASS 7305/7314/7316交流接地阻*测试仪【行业现状】 我国的电力基本建设发展很快,随着系统额定电压等级的*,高电压、大容量的变电所日益增多,出现了许多大型、*型的接地网。接地网的工作状况直接关系到人身*、电力设备和电力系统的*运行。科学合理地测试接地网的各种特性参数,准确评估接地网的*状态,对*电力系统的**运行和变电站工作人员的人身*具有十分重要的意义。 之前受测试设备技术水平的限制,对于接地网的测试往往*局限于测量接地电阻的大小。实际上对于大型地网,“接地电阻”呈现出较明显的“复数阻*”性质,即包含电阻分量、电*分量,所以应当采用“接地阻*”的概念取代“接地电阻”。另外,接地阻*也不是判断接地网是否*为*指标。如在高土壤电阻率地区,欲降低变电所地网的接地阻*值,不*十分困难,而且往往很不经济、也很不合理。
