摘要
从仪表校验通用技术要求入手,研制了交直流多功能标准表、直流恒流电流源、直流恒压电压源及仪表程控校验软件。研制出以交直流多功能标准表为标准,高稳定交直流功率源为辅助电源的精密交直流电表校验装置。实现了对模拟式、数字式各型电参量仪表的自动或半自动校验。已形成系列等级装置并广泛应用。本文重点阐述交直流多功能表高精度、多功能测量原理;直流电源大功率、高稳定度输出的电路特点和性能。介绍了装置的功能和达到的技术指标。
From general specification of measuring instrument calibration obtaining, have developed the AC and DC multifunctional standard instrument, the DC constant current source, the DC constant voltage source and the program-controlled measuring instrument calibration software. Developed precise AC and DC electric instru-ment calibration installment, which have taken the AC and DC muhifunctional standard instrument as the standard and the high stable AC and DC power source as auxiliary power source. Realized automatic or semi-automatic calibration of various analog and digital electricity parameter instruments. Formed the series rank installment and the widespread application. This paper has emphasis narrated high- precision and multi-function of measurement prin-ciple of the AC and DC muhifunctional standard instrument the multi-purpose survey principle with emphasis; the circuit characteristic and the capability of DC power source which has high-power and high stability output. Intro-duced the function of the installment and achieved technical specification.
