摘要

继电保护和测控装置等智能电子设备下放直接安装在开关柜上已经成为一种标准典型方案

也尝试将其安装在GIS开关柜上

但不时发生原因不明的继电保护误动作使人们怀疑这种方案的可行性。实际上

现行的电磁兼容标准已经满足需要。为了确保智能电子设备能够耐受就地安装的电磁干扰水平

正常发挥功能

智能电子设备应按照最新最严酷的电磁兼容标准进行开发和试验;宜将就地安装的智能电子设备作为高压开关设备和控制设备辅助和控制回路的一部分

参与其所有的型式试验;工程设计时特别注意一次二次系统接地方面的安排;现场施工严格按照设计和施工要求进行;日常维护时也应特别注意检查接地等电磁兼容措施的完好性。

Abstract

Protection and control device and other intelligent electronic equipment decentralized direct installation in the switchgear has become a typical scheme

will also be installed in the GIS switchgear.But the sporadic misoperation caused by unknown reason of relay protection still make people doubt the feasibility of this scheme.In fact

the current EMC standard has met the need.In order to ensure that it can tolerate local mounted electromagnetic interference level

and function

intelligent electronic equipment should develop and test in accordance with the most severe and the latest EMC standard.Intelligent electronic devices should be tested as part of a high-voltage switchgear and controlgear and control circuit in all type tests.We must pay special attention to the engineering design about the earthing arrangements in primary and secondary system.We must construct in strict accordance with the requirements of design and construction.We should also pay special attention to check the integrity of the EMC measures

such as grounding

during routine maintenance.
