一、概述分压箱是用补偿法测量直流高电压所必需的测量元件。一般用标准分压箱与整体对比或用数字电压表测量输入输出电压来对其进行整体检定,而这就需要一套高精度的检定设备。为了减少投资,本文根据基层计量站分压箱精度较低(±0.03％),在漏电流等可忽略的情况下,引用电阻仪器元件检定的基本原理和误差理论的规则,提出一种简便易行的方法——元件检定法。 First, an overview of the pressure tank is the compensation method to measure DC high voltage necessary for measuring components. Generally use the standard partial pressure box with the overall contrast or digital voltmeter to measure the input and output voltage to its overall verification, which requires a set of high-precision verification equipment. In order to reduce the investment, according to the accuracy of the substation box at the primary metering station is low (± 0.03%), in the case of negligible leakage current, the basic principles of the verification of the resistance instrument components and the rules of the error theory are proposed. Line method - component test method.
