Description
技术领域technical field
本实用新型涉及一种安全帽，具体地说是一种具备六氟化硫报警功能的安全帽。The utility model relates to a safety helmet, in particular to a safety helmet with the alarm function of sulfur hexafluoride.
背景技术Background technique
目前，在变电站中GIS(组合电器)的应用越来越广泛。GIS是将断路器、隔离开关、接地刀闸、母线、互感器、避雷器等设备集中置于封闭外壳中，充以六氟化硫气体(SF6)作为绝缘介质的组合式设备。与传统敞开式设备相比，GIS基本不受外界环境因素影响，运行可靠性较高。GIS运行的主要问题是内部的六氟化硫泄露，六氟化硫气体一旦泄露至外界环境中，对人体会造成伤害。当前采取的主要预防措施是保持通风，并在GIS设备室安装六氟化硫气体泄露报警仪，在六氟化硫气体含量超标时发出报警。在正常运行中，变电站中的六氟化硫气体泄露报警仪由于定期检验不便，会有装置失灵的情况发生，由于没有其他安全报警装置，这就给运行工作带来了一定风险。At present, the application of GIS (combined electrical appliances) in substations is more and more extensive. GIS is a combined device that places circuit breakers, disconnectors, grounding switches, busbars, transformers, lightning arresters and other equipment in a closed enclosure and is filled with sulfur hexafluoride gas (SF 6 ) as the insulating medium. Compared with traditional open equipment, GIS is basically not affected by external environmental factors, and its operation reliability is higher. The main problem in the operation of GIS is the leakage of internal sulfur hexafluoride. Once the sulfur hexafluoride gas leaks into the external environment, it will cause harm to the human body. The main preventive measures currently taken are to maintain ventilation and install a sulfur hexafluoride gas leakage alarm in the GIS equipment room, which will send out an alarm when the sulfur hexafluoride gas content exceeds the standard. In normal operation, the SF6 gas leakage alarm device in the substation is inconvenient due to regular inspection, and the device may fail. Since there are no other safety alarm devices, this brings certain risks to the operation.
