1992年6月9日上午,我厂机电部电修车间电工甲、乙奉命去调换型钢分厂二车间三道车主电机转子接头。他们在确认高压系统停电措施符合规定的条件下,按施工要求锯掉因发热而被氧化了的转子电缆接头,重新压制新接头。电缆头被锯掉一截后,造成电缆长度不够.为了解决这个问题,甲进入主电机下面的地坑,准备拆除转子电缆抱箍,将电缆上移。甲在拧松抱箍上的螺丝,脱开抱箍的瞬时,触电倒地. 电缆抱箍怎会带电?原来抱箍上接有一根用作照明灯零线的“中性”线,当“中性”线与大地连接时,照明灯的负载电流通过拖箍向大地散发,抱箍呈中性。当“中性”线与大地脱开时,该“中性”线即与照明灯的“火线”等电位,此时,人体接触抱
On the morning of June 9, 1992, the electrician workshop A and B of the workshop of the electromechanical department of our factory were ordered to exchange three rotor joints of the three car owners of the steel plant. They confirm that the high-voltage system power outages under the conditions specified in accordance with the requirements of construction sawing off the rotor due to oxidation of the rotor cable connector, re-press the new connector. In order to solve this problem, enter the pit under the main motor and prepare to remove the rotor cable hoop and move the cable upwards. A loosen the hoop on the screw, remove the hoop at the moment, the electric shock fell to the ground.However, the hoop hoop will be charged? The original hoop is connected to a neutral light for the lighting of the “neutral” line, when the “ Neutral ”When the cable is connected to the earth, the load current of the lamp is distributed to the earth through the dragging bracket, and the clamp is neutral. When the “neutral” line is disconnected from the ground, the “neutral” line is equal to the “live line” of the lighting, at which point the human body contacts
