1.电路故障引发自燃引起装载机自燃的电路故障主要有过载、短路、搭铁不良、关键电器元件功能失效、接触电阻过大、私自改装和线束走向布置不合理等。(1)过载电路过载多因电器元件损坏或使用者私自改装、增大负载等造成的。主要表现为私自安装空调系统,私自改用大功率灯泡或私自增加灯的数量。如此私自改装后,线束支路因负载变大而电流相应增加,如长时间工作(如前大灯、
1. Circuit failure caused by spontaneous combustion Loader spontaneous combustion circuit failures are mainly overload, short circuit, poor grounding, key electrical components function failure, contact resistance is too large, unauthorized modification and wiring harness to the layout of unreasonable. (1) overload circuit overload and more due to electrical components damaged or modified by the user, increasing the load caused. Mainly manifested in the unauthorized installation of air conditioning systems, unauthorized use of high-power light bulbs or unauthorized increase the number of lamps. So privately modified, the harness branch because the load becomes larger and the current corresponding increase, such as long hours of work (such as headlights,
