2 避免形成触电回路的安全操作技术
为了防止形成上述三种触电回路,电工在进行低压带电检修工作时,必须同时严格贯彻以下三点安全操作原则:
(1) 单线操作:在检修工作时,人体在任何时间都不可分别触及两个线头,或两个接线端子,或两个触点,必须一个线头一个线头加工。凡有可能因不慎而触及的邻近带电裸导线,必须预先加以遮护。
(2) 与大地隔绝:电工在检修时,人体各部分必须与大地(包括与大地有连通的可导电的建筑物及管道)有可靠的绝缘隔离。因此,电工必须严格按照安全工作规程穿着电工绝缘鞋、防护工作服和用带有绝缘手柄的工具,以及采用竹或木结构的干燥梯子登高。如不等高,可用干燥的木板等绝缘物垫在下面,同时,在操作时人体不可触及建筑物。此外,在接受未与大地隔离人员递交工具或零件时,检修者必须停止操作,双手必须脱离检修点。这样,才能避免形成线地间的触电回路。
