油料流动会产生静电,静电超过一定极限将产生静电放电,直接影响着油库安全。领油单位从油库领取油料时大多数使用汽车油罐车,为了及时导走加油过程中产生的静电,通常使用专用接地线。目前,油库大多数使用“接地夹”将汽车油罐车与大地连为一体以防静电积聚。去年用万用表抽查了500多辆汽车油罐车的接地电阻,从中发现80％的接地电阻为无穷大,20％的接地电阻小于100Ω。造成接触不良的王要原因是,接地夹与油罐车接触部分被漆皮隔开,表面看有接地而实际并没有真正接地,长此下去将严重影响着油库、加油站的安全。解决的
Oil flow will produce static electricity, static electricity will exceed a certain limit will produce electrostatic discharge, a direct impact on the safety of oil depots. Most units that receive oil from oil depots use car tankers. In order to guide the static electricity generated during refueling in time, a dedicated grounding wire is usually used. At present, the majority of depots use “earth clamps” to connect car tankers to the ground to prevent static buildup. Last year, using a multimeter to check more than 500 cars tanker grounding resistance, from which 80% of the grounding resistance found to be infinity, 20% of the grounding resistance is less than 100Ω. The reason for the poor contact is that the contact between the grounding clip and the tanker is separated by a patent leather. The surface is grounded but not actually grounded. If the situation continues, it will seriously affect the safety of oil depots and gas stations. fixed
