由于种种原因,我国工程机械往往在同一台产品上采用24伏和12伏两种供电方式。最常见的有W1001挖掘机、Y2-12/15压路机、CL-7自行式铲运机等。这些机械均采用电源为24伏(蓄电池、发电机、调节器),而用电设备却为24伏和12伏两种。采用上述两种供电方式后,机器白天作业不用灯光时,供电系统正常,而夜间作业时, Due to various reasons, China’s construction machinery often uses 24 volt and 12 volt power supply methods on the same product. The most common are W1001 excavators, Y2-12/15 rollers, and CL-7 self-propelled scrapers. These machines all use 24 volts (batteries, generators, regulators), while the power devices are 24 volts and 12 volts. After adopting the above two kinds of power supply modes, when the machine does not use light during the daytime operation, the power supply system is normal, and at night,
