【摘要】 全封闭组合绝缘GIS设备安装后需要对气室抽真空、氮气和SF6气体,抽真空设备配有涡轮油增压泵,以提高抽真空的功率和真空度。如果发生停电或者设备故障,真空泵就会停机,由于气室的压强接近于真空状态,值班人员如果未能及时关闭抽真空阀门,会发生气室将真空泵的油倒吸进气室内的严重后果。值班人员需要看守多台抽真空设备,同时长时间的值班会使值班人员麻痹大意,不能可靠保证抽真空工作的安全。研制了一种可靠的抽真空设备停电报警装置,采用无源设计,停电后无需额外提供电源,同时安装使用方便。抽真空设备停机后发出声音报警,通过技术手段防止事故的发生,并且能够减轻值班人员的负担,有非常高的实用价值。更多还原

【Abstract】 The gas chamber needs vacuum,nitrogen and SF6 gas after GIS equipment installation of closed combination insulation,vacuum equipment equips turbine oil booster pump to increase the power and vacuum degree of vacuum.If a power outage or equipment failure,the vacuum pump will be shut down,due to the pressure of the gas chamber close to the vacuum state,the duty officer failed to close the vacuum valve will happen down the gas chamber vacuum pump oil sucked into the serious consequences of the gas chamber.Duty personnel need to guard multiple vacuum equipment,at the same time,personnel will be careless when being on duty for a long time,can not reliably guarantee pumped vacuum work safety.Developed a reliable vacuum equipment outage alarm device,the use of passive design,it does not additional power supply after power failure,at the same time,installation is easy to use.It will sound alarm after vacuum equipment downtime,through technical means to prevent the occurrence of the accident,and to alleviate the burden of the duty officer,which has very high practical value.更多还原
