中国西部电网电击猛禽致死事故调查

2004～2008年调查了西部电网电击猛禽情况.调查区域包括新疆、青海、四川、甘肃、西藏等省区.共统计10 kV和35 kV输电线路长度178 km、杆塔数1 800余根;收集线路附近鸟的尸体、羽毛、残骸等110件,用于鉴定鸟种.调查结果,被电死猛禽计79只(10 kv),平均每千米输电线路1.36只,11.31%的杆塔对鸟类构成威胁;35 kV输电线路上鸟巢数44个,平均每千米输电线路O.37个,至少6.06%杆塔被猛禽利用.已知24%～40%的跳闸停电事故是由于鸟类引发的.症结分析,西部电网结构设计不合理.线路裸露,缺乏防鸟措施.在西部约20%左右的猛禽(11种)受到电击的威胁,同时严重影响着输电线路安全运行.本文提出了合理化建议.     

Nematode Electrocution

The effects of electric shock on Panagrellus redivivus adults and larvae and Meloidogyne incognita acrita larvae were studied. The nematodes were placed in tap water between two stainless steel electrodes, spaced 2 mm apart and cemented to a glass slide. Electric potentials of 1, 5, 10, 15, 20, 30, and 60 vdc/mm and vac/mm were applied for periods of 1 sec to 5 rain at 0.05 to 77 ma. The results demonstrated that ac or dc electric shocks as low as 5 v/mm for larvae and 10 v/mm for adults can be lethal. Some larvae and eggs within the body of P. redivivus females were not affected at 600 v/ram. Potentials of 20 and 60 vdc/mm for 2-sec stimulated hatch of Meloidogyne eggs.     

Brugada-type Electrocardiographic Pattern Induced by Electrocution

Heart is one of the most frequently affected organs in electrocution. Electrical injury can cause life-threatening cardiac complications such as asystole, ventricular fibrillation, and myocardial rupture. In this case report, we describe a 22-yr-old male patient who sustained electric burn injury and presented with electrocardiogram showing transient Brugada type pattern.
