直流分压箱标准装置

直流电阻分压箱（简称分压箱），是一个具有一个或几个固定比率提供输出电压等于输入电压预定分数电阻网络组成的装置。输入和输出电压二者各自在一对端钮之间。随着现代科学技术的发展，该标准已经被广泛应用于各个技术领域和国防科技建设。其标准是确保电气产品的安全可靠及产品质量的准确可靠及人民群众的生命安全。完善其溯源体系。建立直流高阻标准检定装置是非常重要和必要的。分压箱可以作为直流电位差计的量程扩展器。定阻输入式分压箱的检定采用电压比法，即由标准直流电压发生器输入电压，精密数字电压表测得分压箱的输出电压，计算分压比：1.1kV 以下

DC resistance voltage divider (hereinafter referred to as voltage divider) is a device consisting of a resistive network with one or more fixed ratios, which provides an output voltage equal to a predetermined fraction of the input voltage. The input and output voltages each exist between a pair of terminals. With the development of modern science and technology, this device has been widely applied in various technical fields and national defense science and technology construction. It serves to ensure the safety and reliability of electrical products, the accuracy and reliability of product quality, and the safety of people's lives. It is highly important and necessary to improve its traceability system and establish a DC high-resistance standard calibration device. A voltage divider can act as a range extender for DC potentiometers. The calibration of fixed-resistance input voltage dividers adopts the voltage ratio method: a standard DC voltage generator provides the input voltage, a precision digital voltmeter measures the output voltage of the voltage divider, and the voltage division ratio is calculated for voltages below 1.1 kV.
