由于起重机设备使用的场合很多,面临着各种各样恶劣的应用环境,如高温、高寒、潮湿、酸碱盐雾、粉尘等,还有复杂的电磁环境(强电磁场干扰、雷电、因起吊物品重量变化导致电机负荷变化而导致电流电压波动)、器件发热老化导致系统故障,以及操作人员误操作导致的紧急状况等。这些都需要研发人员在进行起重机控制系统设计之初,就采取相应的应对措施(包括机械结构、软件和硬件可靠性设计),以增强系统的鲁棒性和可靠性,保证设备和人身财产安全。

起重机设备常见的电气方面的失效模式(故障模式)有短路(电机线圈过流而过热)、失压、过压、断错相等。针对起重机设备常见的这些故障失效模式,全球电路保护器件的领先供应商力特(LITTELFUSE)提供了完善的解决方案,可对这些故障进行有效地预防和保护。


力特的保护器件在起重机设备中的应用位置如下:

1)电源输入及电机驱动保护,如下图1所示:


图1:电源输入及电机驱动保护方案


主电路保护包括大电流保险丝、MOV(压敏电阻 )和GTS(气体放电管),高压AC差分保护,IGBT的VCE,门极瞬态过压保护(TVS),如下图2所示。另外,如果变频控制器驱动离电机较远的话,还可以在输出的U、V、W各相线上加压敏电阻进行保护。


图2:IGBT的VCE、门极瞬态过压保护


2)通信接口的保护
起重机控制系统通常由多个子系统构成,而各个子系统之间需要各种通信接口如(RS485、RS232、AN、Ethernet或者无线的方式)进行数据和控制信号的交换和传输。并且各个子系统不可能完全是安装在一个位置,而需要通过线缆进行连接,难免会受到外界干扰。因此在相应的输入输出接口上需要采取相应的保护措施。下图3、4、5分别是RS485、RS232及CAN接口的保护实现(采用TVS)。


图3:RS485接口保护

图4:RS232接口保护


CAN接口保护

总结:鉴于起重机设备在人们的生产、生活的各个方面都用得越来越多,对提高生产效率,也起着越来越重要的作用,因此其系统的可靠性、安全性也是至关重要的,其中的保护器件也发挥着不可估量的重要作用。
