SSR 组件的接地/接地 - 30/06/2020

如何确保 SSR 组件的接地/接地? 接地是通过低电阻电线或电缆将即时放电直接传输到地面的方法。 因此,它是设置一切以避免火灾或电击自己最重要的部分之一。这相当重要! 因此,当然有许多方法可以接地您的固态继电器,我们将在本文中介绍一些。 固态继电器是否需要接地? 一般来说,任何金属都需要接地…固态继电器的底座是金属…因此,如果 SSR 安装在金属外壳内,则外壳必须接地或盖住,以防范危险电压。 决定实施两种保护措施中的哪一项取决于设计以及开关设备在打开电源时是否通电。 如果确保开关设备只能在不通电才能接触,则无需接地。 如果无法确保这一点,则需要接地。 EN 60947-1 怎么说? “Exposed conductive parts which could be dangerous must be electrically connected to one another and to a protective conductor connection which is in turn connected to a ground connection.” 可能危险的暴露导电部件必须相互电气连接,并连接到保护导体连接,而保护导体连接又连接到接地连接。 EN60947-1 不需要任何测试。因此,我们建议根据 EN60950-1 测试您的安装。 如果将产品安装在面板上,如何将产品接地连接到面板? 如果我们的 SSR 固定在金属板上,则其板的接地由固定螺钉完成。组件的接地必须用导线、卡舌和螺栓通过固定螺钉的单独孔连接完成。如果对板进行涂漆,则必须在固定螺钉和保护接地连接周围拆下油漆。 此情况很常见,此解决方案符合 […]

Thermal Interface Materials - 10/03/2020

Thermal Pads or Thermal Paste : How making the right choice ? The surface of a SSR or a heatsink is never entirely flat. If you mount a Solid State Relay directly on a heatsink, there will be invisible gaps between the two parts. Since air conducts heat poorly, these gaps have a very negative […]
