摘　　要：针对目前电车使用过程中出现的各种电器和线路故障问题,本文从电器线路抗干扰能力提升的角度出发,分别从并联DC-DC分流电阻、DC-DC负极隔离、外接续流二极管、增加静电泄放器4个方面进行设计改进。事实证明,通过对电器线路做以上改进措施,线路的抗干扰能力增强,电器使用的故障率大大降低。In view of the various electrical and circuit faults in the current use of electric forklifts,the design is improved in the following four aspects that includes parallel DC-DC shunt resistors,DC-DC negative isolation,external freewheeling diodes,the addition of electrostatic bleeder from the perspective of improving the anti-interference ability of electrical lines.Facts have proved that by taking the above improvement measures,the anti-interference ability of the circuit is enhanced,and the failure rate of electrical load in use is greatly reduced.
