电工作业中,弧光烧伤事故时有发生。为防止此类事故的发生,应做到以下三点: (1)操作前应穿着棉质工作服,戴好护目镜、防护手套、安全帽。袖口要扎紧。 (2)在低压操作拉合刀闸时,身体不要面对刀闸,要站在刀闸一侧;拉合刀闸的瞬间将头侧转,不要目视刀闸。用试电笔验电或用万用表测量三相交流相间、对地电压时,以及用尺在带电体附近测量时应特别注意防止短路。用试电笔验三相交流电时,试电笔不要横在三裸露电极中间进行测量,测量时不要用力,防止滑落造成短路。用万用表测三相电压时一定要首先根据所测量的电压定好档位,如果测三相交流电中某相对地电压,应先用
In electrical work, arc burns happen from time to time. To prevent such accidents, should do the following three points: (1) before the operation should wear cotton overalls, wear goggles, protective gloves, helmets. Tight cuffs. (2) pull the knife in the low-voltage operation, the body do not face the knife gate, to stand knife side; pull the knife the moment the head side turn, do not visual knife. Use a test pencil test or a multimeter to measure the three-phase alternating current, ground voltage, and ruler in the vicinity of the charged body with special precautions should be taken to prevent short circuit. Trying to test the three-phase AC power with the test lead, do not cross the test electrode in the middle of the three exposed electrodes, do not use force to prevent the sensor from slipping. When using a multimeter to measure the three-phase voltage, you must first set the gear according to the measured voltage. If you measure a certain relative voltage in the three-phase alternating current, you should use
