【应用】高可靠性电流互感器CT91 100 231 WR在开关电源上的应用
EXXELIA 集团提供产品具有高性能、超高可靠性的特点,能够满足欧洲航天总署 (ESA) 认证的产品、美军标、CECC认证等苛刻条件认证。其产品广泛应用于国防、军工、航空航天以及石油、铁路、医疗、通讯等高端领域。其推出应用于高可靠性开关电源上的电流互感器CT91 100 231 WR完全能够应付复杂苛刻的环境条件。
脉冲控制的开关电源经过变压器后的电路如下图1所示,在变压器后增加电流互感器,可以检测输出电路的电流大小。
图1 电流互感器在开关电源中的应用
在脉冲控制的开关电源中应用电流互感器检测电流,对电流互感器主要指标要求有:
额定变比-一次额定电流和二次额定电流之比,即被检测电路电流与互感电流的比值,互感电流的大小决定了RL的电压,根据后续检测电路的范围,确定合适的额定变比;
一次内阻-一次电路的内阻,内阻越小,电流互感器对一次电流影响越小,压差越小;
工作频率-根据一次电路的工作频率进行选择,频率范围必须包含一次电路的频率;
最大承受峰值电流-能够工作的一次电路的最高峰值电流;
隔离阻抗-表示一次电路与二次电路之间的隔离度,隔离阻抗越大,隔离度越高。
CT91 100 231 WR的额定变比是1:100,通过测试RL的电压计算主电路中的电流;工作频率为9kHz to 200kHz,能够满足大多数应用;其拥有<2mΩ的极小输入阻抗,对主电路的影响可以忽略;最大承受峰值电流达10A,其尺寸只有10.7mmX13.4mm,小尺寸大电流;在500V测试的隔离阻抗大于1GΩ,隔离度更高。其详细参数如下图2所示。
图2 电流互感器CT91xxx231WR的参数列表
相比于优秀的性能表现,CT91 100 231 WR在可靠性方面的表现更具优势。工作温度为: – 55 °C to + 125 °C,能够满足ESCC-3201 generic ( including MIL-STD-202 ) / ECSS-Q-70-02等标准,其采用一体成型压接的独特工艺(产品实物图如图3所示),保证长期稳定工作,在可靠性方面毋庸置疑。

选用漏电保护装置应当考虑哪些方面的因素?
选用漏电保护装置,首先是正确选择漏电保护装置的漏电动作电流。 1)在浴室、游泳池及隧道等触电危险性很大的场所,应选用高灵敏度、快速型漏电保护装置(动作电流不宜超过 10mA)。 2)如果安装场所发生人触电事故时,能得到其他人的帮助及时脱离电源,则漏电保护装置的动作电流可以大于摆脱电流。如果是快速型保护装置,动作电流可按心室颤动电流选取。如果是前级保护,即分保护前面的总保护,则动作电流可超过心室颤动电流。如果作业场所得不到其他人的帮助及时脱离电源,则漏电保护装置动作电流不应超过摆脱电流。 3)在触电后可能导致严重二次事故的场合,应选用动作电流 6mA 的快速型漏电保护装置。为了保护儿童或病人,也应采用动作电流 10mA 以下的快速型漏电保护装置。对于Ⅰ类手持电动工具,应视其工作场所危险性的大小,安装动作电流 10~30mA 的快速型漏电保护装置。选择动作电流还应考虑误动作的可能性,保护器应能避开线路不平衡的泄漏电流而不动作;还应能在安装位置可能出现的电磁干扰下不误动作。选择动作电流还应考虑保护器制造的实际条件。 4)用于防止漏电火灾的漏电报警装置宜采用中灵敏度的漏电保护装置。其动作电流可在25~1000mA 内选择。 5)连接室外架空线路的电气设备应装用冲击电压不动作型漏电保护装置。 6)对于电动机,选用的漏电保护器应能躲过电动机的启动漏电电流(100kW 的电动机可达 15mA)而不动作。选用的漏电保护器应有较好的平衡特性,以避免在数倍于额定电流的堵转电流的冲击下误动作。对于不允许停转的电动机应采用漏电报警方式,而不应采用漏电切断方式。 7)对于照明线路,宜根据泄漏电流的大小和分布,采用分级保护的方式。支线上选用高灵敏度的漏电保护器,干线上选用中灵敏度漏电保护器。 8)在建筑工地、金属构架上等触电危险性大的场合,Ⅰ类携带式设备或移动式设备应配用高灵敏度漏电保护装置。电热设备的绝缘电阻随着温度变化在很大的范围内波动。例如,聚乙烯绝缘材料 60℃时的绝缘电阻仅为 20℃时的几十分之一。因此,应按热态漏电状况选择漏电保护器的动作电流。 9)对于电焊机,应考虑保护器的正常工作不受电焊的短时冲击电流、电流急剧的变化及电源电压的波动的影响。对高频焊机,漏电保护器还应有良好的抗电磁干扰性能。 10) 对于有非线性零件而产生高次谐波及对有整流零件的设备,应采用零序电流互感器二次侧接有滤波电容的保护器,而且互感器铁心应选用剩磁低的软磁材料制成。 11) 漏电保护装置的极数应按线路特征选择。单相线路选用二极保护器,仅带三相负载的三相线路或三相设备可选用三极保护器,动力与照明合用的三相四线线路和三相照明线路必须选用四极保护器。 12) 漏电开关的额定电压、额定电流及分断能力等性能指标应与线路条件相适应。漏电保护装置的类型与供电线路、供电方式、系统接地类型及用电设备特征相适应。
