你可以把电源看作水库，我们大楼内的家家户户都需要供水，这时候，水不是直接来自于水库，那样距离太远了，等水过来，我们已经渴的不行了。实际水是来自于大楼顶上的水塔,水塔其实是一个buffer的作用。如果微观来看，高频器件在工作的时候，其电流是不连续的，而且频率很高，而器件VCC到电源有一段距离，即便距离不长，在频率很高的情况下，阻抗Z=i*wL+R，线路的电感影响也会非常大，会导致器件在需要电流的时候，不能被及时供给。

ZigBee技术被认为是*有可能像WiF蓝牙一样改变我们现在生活的通信技术之ZigBee是让一些设备特别是传感器接入互联网的技术。在家庭自动化控制和工业遥测遥控领域，对无线数据通信的需求越来越强烈,且这种无线数据传输必需是高可靠的，并能抵抗现场的各种电磁干扰。Zigbee的特点就在于功耗更低，实时在线、同一个网关接入数量巨大并且可以自组网,在物联网的发展中具有广阔的应用空间。Zigbee技术Zigbee一词源自蜜蜂群在发现花粉位置时，通过跳ZigZag形舞蹈来告知同伴，达到交换信息的目的。

分工频耐压试验和直流耐压试验两种。工频耐压试验其试验电压为被试设备额定电压的一倍多至数倍，不低于1000V。其加压时间：对于以瓷和液体为主要绝缘的设备为1分钟，对于以有机固体为主要绝缘的设备为5分钟，对于电压互感器为3分钟，对于油浸电力电缆为10分钟。电气设备经耐压试验能够发现绝缘的局部缺陷、受潮及老化。交流耐压试验：在被试设备电压的2.5倍及以上进行，从介质损失的热击穿观点出发，可以有效地发现局部游离性缺陷及绝缘老化的弱点。
