目前检验分压箱一般采用测量电阻的方法,其缺点是,不能全部在额定电压下进行检验,与实际使用时不一致。本文介绍利用国产过渡电阻组成标准比值,在300伏下检验分压箱的方法,具有一定的实用意义。一、标准比值的组成和测定将10~4欧过渡电阻的第一到第九个电阻和电阻箱M(可采用ZX54或ZX25-1)串联组成标准比值。电阻箱作为检验分压箱时的读数盘,其名义值为10~4欧,为了在检验分压箱时
At present, the partial pressure tank is usually tested by the method of measuring the resistance. The disadvantage is that all of the partial pressure tanks can not be tested under the rated voltage and are inconsistent with the actual use. This article describes the use of domestic transition resistance composed of standard ratio, at 300 volts to test the method of partial pressure tank, has some practical significance. First, the standard ratio of the composition and determination The 10 ~ 4 Europe transition resistance of the first to ninth resistance and resistance box M (ZX54 or ZX25-1 can be used) in series to form a standard ratio. Resistance box as a test sub-pressure box when the reading plate, the nominal value of 10 ~ 4 Europe, in order to test the partial pressure tank
