摘要
气体绝缘全封闭组合电器(GIS),在国内一般采用露天环境布置,其结构筒体经年累月历经酷暑严寒而发生热胀冷缩,由此可能导致筒体变形、支座开裂、膨胀节损坏、绝缘盆子破裂、SF6气体泄漏等事故。对此使用光纤光栅技术对GIS运行过程中筒体、膨胀节等部位的温度、应力、位移等关键数据进行监测,能够有效避免问题,保证GIS的运行安全。
GIS is generally arranged in an open environment in China.Its structural cylinder undergoes thermal expansion and contraction after years of intense heat and cold,which may cause deformation of the cylinder,cracking of the support,damage to the expansion joint,rupture of the insulating basin,and SF6 gas leakage.Compare with the use of fiber bragg grating technology to monitor the temperature,stress,displacement and other key data of the cylinder,expansion joints and other parts during the operation of the GIS.It can effectively avoid the problem and canensure the safe operation of the GIS.
