【应用】30A/500VAC陶瓷管状插件保险丝用于30KW充电桩模块,分断能力高达30KA
随着新能源汽车的技术发展和市场的不断扩大,使得直流充电桩也得到了快速迅猛发展。目前30KW左右的模块,基本都采用三相交流供电。在三相交流输入端都会串保险丝,以确保产品发生过流或短路时,能及时物理切断供电回路,防止故障进一步扩大或造成火害事故。
电安的西北某客户30KW充电桩模块上,考虑到电压波动下限,和保险丝工作环境温度等方面的余量,需要选6x32mm,72A左右,500Vac的陶瓷管保险丝。综合考虑产品余量、性能、成本等方面因素,客户选择了电安科技陶瓷管状插件保险丝CA433A030PV3(30A 500Vac 带引线封装),在每相线上各并了3个。单个保险丝分断能力,在500Vac电压下,可以达到30KA,完全可以满足产品保护要求,目前项目已经大批量产。
其应用框图如下图所示:
CA433产品图片和参数
它有三种封装方式,可供客户灵活选择。
特点如下:
1、最大额定电压1000V,额定电流0.2A至30A,分断能力高达30KA,可适用于单相或三相供电电路的过流保护;
2、三种安装方式可选,安全性高,成本低;
3、6mm*32mm紧凑本体尺寸,可以减少大功率设备的PCB布局空间,为其他保护器件预留空间;;
4、工作温度范围从-50℃到125℃的宽工作温度范围,在极端环境温度下,提供更为可靠的保护;
5、全系列通过UL认证,认证号为E500586。

The Cartridge fuse CA433 of DA Technology has been successfully applied in the overcurrent protection of the lithium battery formation system
When the overcurrent occurs, the MCU that controls the on and off of the MOS or relay has a software failure and cannot issue a command to open the circuit. The heat generated by the circuit is very likely to cause damage to the circuit of the formation device, or even fire. At this time, it is recommended to put a fuse (such as CA433) in series on the circuit to achieve complete physical disconnection, which can effectively prevent this danger from occurring.

工业电源输入电压一般在AC380V-690V,其输入的保险丝选型时一般需要选高达1000V耐压的保险丝。目前1000VAC的高压保险丝多以进口为主,在目前国产化的需求下,电安科技推出的CA433系列高压大电流管状保险丝,解决了工业电源输入保险丝国产化的问题。

【应用】插件保险丝用于锂电池化成柜的过流保护,能实现完全的物理断开,防止化成设备电路损坏
如当过流发生的同时,控制MOS或继电器通断的MCU发生软件方面的故障,不能发出断开回路的命令时,电路产生的热量极有可能会导致化成设备电路的损坏,甚至起火。此时推荐在电路上串上保险丝(如CA433)就能实现完全的物理断开,可以有效防止此危险的发生。
