随着国民经济的全面发展高层建筑物越来越高,对塔式起重机性能的要求也越来越高。塔式起重机的性能在电气控制方面是主要的因素,而电气工艺布置的不合理,如橡套电缆的固定,大部分采用卡子卡的方式或者局部固定电缆部位采用穿铁管敷设。当你用卡子固定时将电缆卡太紧了很容易使电缆内部绝缘破坏,造成短路;卡太松了造成电缆脱落致使电缆外橡套绝缘损坏。电缆卡子的固定全靠经验,但这种经验又不易掌握。据我们了解塔式起重机上各种电缆的损坏,绝大部分都是用卡
With the overall development of the national economy, high-rise buildings are getting higher and higher, and the performance of tower cranes is also increasing. Tower crane performance is the main factor in the electrical control, and the electrical process layout is unreasonable, such as the fixed rubber cable, most of the use of card card or partial fixed cable location using iron pipe laying. When you use the clips to fix the cable card too tight, it is easy to damage the internal insulation of the cable and cause a short circuit. The card is loose and the cable is dropped and the rubber sleeve insulation of the cable is damaged. The fixing of cable clamps depends entirely on experience, but this experience is not easy to grasp. According to our understanding of the damage of various cables on tower cranes, most of them are used cards.
