加油加气站雷击静电事故分析及安全防护技术

雷击主要损坏加油加气站电子系统设备并引发一系列危害,大都是雷电波侵入和雷电反击造成,静电易引发火灾和爆炸。结合近几年来,山东省淄博地区汽车加油加气站现有防雷防静电装置的检测（验收）情况,归纳出缺少防直击雷装置、缺失SPD防护、未共用同一地网等五个方面的重大安全隐患,并逐一给出整改措施。对大型加油加气站应依据雷电灾害风险评估来确定其防雷类别,新建站的防雷防静电装置应严格按照设计、施工和验收＂三同时＂原则,建立雷击静电事故应急处置预案和定期检测与维护防雷防静电装置是加油加气站安全生产的重要关键环节。

Analysis and Countermeasure about Lightning Static electricity Accident of Automobile Gasoline and Gas Filling Station

The reasons of accidents about lightning stroke and static electricity of automobile gasoline and gas filling station were investigated and analyzed in the spots. The accidents main damaged the filling station electron informa- tion system equipment and initiated a series of harms, and they are mostly induced by lightning surge on incoming services and back flashover creates. Static electricity is easily to cause the fire and burst. In the last few years, combining the test situation of existing lightning and static protection system of the filling station in Zibo area Shan- dong Province, five great potential safe hazard were summarized, induding lack direct lightning flash protection sys- tem, lack SPD protection, sharing the same ground network, etc. and the measures of rectification and improvement were proposed one by one. The large-scale filling station should be assessed according to the disasters risk of thun- der and lightning to confirm it＇s classification. The lightning and static protection system of new station should strict- ly insists the principle of according to the design, construction and approval ＂at the same time the threes＂, to pre- vent the congenital security hidden danger. Finally, it was proposed emphatically to establish coping with lightning and static accident emergency document, regularly test and maintain lightning and static protection system, all of these are key link of safety in the filling production.
