随着新能源汽车的蓬勃发展,作为其配套设施的充电桩建设在全国各地逐渐开展起来。有关部门预测,150-240kW直流充电站将是未来发展的趋势,将主要安装在高速公路、大型商场、景区等开阔地带。由于安装在户外,电网供电线路偶尔会受到感应雷的影响,出现雷击浪涌等电压异常情况。如果不采取防雷等保护措施隔离异常的浪涌电压,会造成充电桩内部电路烧坏,从而造成短路或者人体触电死亡等危险事件发生。在新国标中明确规定充电桩需承受的3级浪涌(冲击)抗扰度试验。即:至少需要通过2KV的浪涌测试,其对应的电流至少2KA。直流充电桩AC/DC部分采用三相五线制供电,除了交流配电柜需要做好防雷措施外,功率模块单元的防雷措施也必不可少,AC/DC单元如图1中标记1所示。



图1. 直流充电桩单元模块


在充电桩功率模块中,常用的防雷措施如图2所示,即在三相火线和相线间加装压敏电阻,并在相线和地线间加装气体放电管。对于气体放电管,笔者推荐LITTELFUSE公司生产的交流线路高压气体放电管AC240(如图3所示),该型号直流放电电压600V(额定值),可承受连续10次(@8/20us)5KA浪涌电流冲击,其单次最高承受(@8/20us)10KA浪涌电流,可压制200安培的交流持续电流,满足直流充电桩的浪涌抗扰度试验要求。

图3. AC240轴线引出封装


AC240(外观如图3所示)的直流击穿电压最小480,最大720V,最大直流击穿电压低于后级AC/DC单元功率器件的最大工作电压,且高于三电市电零-相线最高电压1.2倍左右,同时最大脉冲击穿电压(@100V/us)1100V,低于后级整流电路功率器件的最大工作电压,符合设计选型的要求;绝缘电阻达到10GΩ(100V),电容低于1.5PF,接入后产生的漏电流极小,对三相市电相位影响极小;该放电管的工作温度-40~+90℃,达到工业级的温度水平,满足充电桩应用环境要求。


AC240采用牢固的陶瓷金属结构,提供带引线安装和不带引线安装两种封装,其形状为直径8mm、高度6mm的圆柱体,尺寸如图4所示。用户可根据PCB设计要求选择合适的封装。
