摘要
GIS作为电力系统的关键设备之一，其运行的安全可靠至关重要。对某电厂一起220 kV GIS电缆仓内绝缘击穿事故进行分析，根据故障录波图判断，该事故为先发生了单相接地短路，而后发展为三相短路故障。综合解体和检测情况，复原事故过程为：运行过程中，气室内有异物掉落，进入电缆仓内强电场区域，使电场分布畸变，进而引发单相击穿；由于电缆仓和接地开关气室之间未设置气隔盆子，导致单相击穿后的金属融化液飞溅至接地开关支撑盆子上，引发事故扩大，发生三相短路。吸取该事故教训，提出选用不锈钢吸附剂盒、合理预留GIS内部非标部件绝缘裕度、加强设备状态巡检和评估等预防措施，为后续GIS的安全运行和设计优化提供实践依据。
Abstract
GIS is one of critical equipment of power system and its safe and reliable operation is very important. The insulation breakdown in cable compartment of 220 kV GIS in a power plant is analyzed. It is concluded by the judgement of the fault recording diagram that single-phase grounding short circuit occurs firstly
followed by the three-phase short circuit. Based on the disintegration and detection
the accident process is analyzed as follows:during operation
foreign particle drops in the gas compartment and enters into the strong electric field area of the cable compartment
leading to electric field distribution and single-phase breakdown. Since no insulating barrier is set between the cable compartment and the gas compartment of disconnector
the molten metal splashes onto the support spacer of the earthing switch after a single-phase breakdown
leading to the escalation of the accident and resulting in a three-phase short circuit. Drawing lessons from the accident
such preventive measures as selecting stainless steel adsorbent box
reasonably reserving insulation margin of non-standard parts in GIS
strengthening patrolinspection and assessment of equipment status are proposed so to provide practical basis for safe operation and design optimization of GIS in the future.
