本刊1962年10-11期,《电度表的保温》会介绍了采用防寒罩和白炽灯加热的保温办法。此种方法确实很好,但保温罩的施工不够简便。同时为了节省电能,需将罩内温度控制在电度表所需的温度以内,应当考虑自动控制温度变化的装置。我们对这两个问题会进行了研究,目前结合设计文件提出改进的办法。简单介绍在下面,供参考。 In Issue 10-11 of 1962, “The Insulation of Watt-hour Meters” will introduce insulation methods using cold-proof hoods and incandescent lamps. This method is really good, but the construction of the insulation cover is not easy. At the same time, in order to save energy, the temperature inside the hood needs to be controlled within the temperature required by the power meter, and a device that automatically controls the temperature change should be considered. We have conducted a study on these two issues and present improvements in combination with the design documents. A brief introduction below, for reference.
