| 2012年10月，广州一主妇买菜回家，碰上小区在清洗路面，经过电动伸缩门时突然倒地，有人经过想扶起她，双手却被电麻，最后该主妇死亡！ In October 2012, a housewife in Guangzhou came home to buy vegetables. She met the community in cleaning the road, and suddenly fell to the ground through the electric telescopic door. Some people tried to lift her up, but her hands were numbed with electricity. Finally, the housewife died. 2015年7月9日，江西吴女士的6岁儿子，在家门口对面的小区玩耍，被路人发现被夹在电动门与水泥柱之间，抢救无效死亡！ In July 9, 2015, Ms. Wu, a 6 year old son of Jiangxi, was playing in the opposite area at the door. He was caught by passers-by. He was sandwiched between the electric door and the cement column, and died. 原因分析 Cause analysis 电动伸缩门漏电有两种可能： There are two possibilities for electric expansion gate leakage: 一是电缆漏电。因为电缆要随着门伸缩支架来回伸缩，无法进行刚性保护，频繁动作，加大磨损度。机械支架对电缆存在一定的机械伤害风险，一旦划破绝缘保护层，会造成漏电。再有，电缆长期置于室外，高温、雨水、雾气等会加速电缆外皮的老化。 One is cable leakage. Because the cable will expand with the door expansion support, no rigid protection, frequent action, increased wear and tear. The mechanical bracket has a certain risk of mechanical damage to the cable. Once the insulation protection layer is broken, it will cause the leakage of electricity. Again, the cable is placed outside for a long time. High temperature, rain, fog and so on will accelerate the aging of the cable outer skin. 二是电动机漏电。受地面平整度影响，电动机可能会长期在颠簸震动状态下运行，增加电动机器件损伤的危险。另外，绕组受潮使绝缘电阻下降，电动机长期过载运行，有害气体侵蚀，金属异物侵入电阻内部，导线绝缘损坏灼烧等都会引起漏电。 Two is the electric motor leakage. Affected by the ground flatness, the motor may run in a long time of turbulence and vibration, increasing the risk of damage to the motor devices. In addition, the windings are damp, which leads to the decrease of insulation resistance, the long term overload operation of motors, the erosion of harmful gases, the invasion of metal foreign bodies, the insulation damage and ignition of conductors, and so on, which will cause electric leakage. 怎么办？ What should I do? 可采取如下措施，降低安全风险： The following measures can be taken to reduce the risk of security: 1、电缆必须要使用软套管进行保护，套管要有一定应对机械伤害的强度。 1, the cable must be protected by the soft casing, and the casing must have a certain strength to cope with the mechanical damage. 2、必须安装漏电保护器，定期进行试验。 2, the leakage protector must be installed, and the test must be carried out regularly. 3、设定合理的人行开启宽度。以上面的案例为鉴，电动门预留人行通道的宽度至少在0.9-1.2米，这是通用人行出口的宽度值。地面要设定标记，以给操作人员准确的提醒。 3, set the reasonable width of the person to open. In the case of the above, the width of the electric door is at least 0.9-1.2 meters in width, which is the width value of the universal pedestrian exit. The ground must be marked to give the operator an accurate reminder. 4、电动伸缩门的运行地面应保证平整，无异物，减少物理震荡。 4. The operating ground of the electric expansion door should be guaranteed to be flat, without foreign objects, and to reduce the physical concussion. 5、电动门伸缩门应设置警示标志，如当心触电。目前看，尚无此类标志应用在电动伸缩门上。 5, electric door expansion door should be set warning signs, such as beware of electric shock. At present, there is no such sign on the electric expansion door. 6、加强安全检查，落实主体责任。相关责任方要定期对电动伸缩门开展检查，发现隐患即使消除。 6, strengthen the safety inspection and carry out the responsibility of the main body. The responsible party should check the electric expansion door regularly to find out the hidden danger even if it is eliminated. 7、对门卫等操作人员加强培训，发现隐患问题及时报告。 7, the men and other operators and other operators to strengthen training to find hidden problems in time to report. |
