我矿进口设备195B电动挖掘机励磁机正常工作时发出的电源为125V左右,主要供给各部直流电动机励磁电源和各部阀体的控制电源以及拉门机电源和各部发电机励磁的给定电源等,极其重要。在这次的设备检修过程中,调试时发现电子调节板已损坏,励磁机输出电源达到160多V,造成励磁机供电系统无法正常工作。此设备是美国BE公司的产品,价值100多万元,新进1台励磁机最快也需2～3个月,为保证设备正常工作,特此对其励磁机线路进行技术改造。
I imported mine equipment 195B Excavator exciter normal work is issued when the power supply is about 125V, the main supply of various parts of the DC motor excitation power and the control of the valve body power and sliding door power supply and the Ministry of Generator excitation given power, etc., Extremely important. In this equipment overhauling process, the commissioning found that the electronic adjustment board has been damaged, the exciter output power reached more than 160 V, resulting in the exciter power supply system does not work. This equipment is the United States BE company’s products, the value of more than 100 million, the new one as fast as the exciters also need 2 to 3 months, in order to ensure the normal operation of equipment, hereby excite machine line technical transformation.
