Abstract

The invention discloses a full-functional multiple-meter-position checking device for voltage monitors. The full-functional multiple-meter-position checking device is used for testing a plurality of voltage monitors and comprises a host machine, a plurality of error calculators connected with the host machine, a standard source, a power consumption switching and testing module, concentrators connected among the host machine and the voltage monitors, and a bus network for connecting the error calculators, the standard source, and the power consumption switching and testing module with the host machine. The full-functional multiple-meter-position checking device can be used for simultaneously and automatically checking all items of the multiple voltage monitors, thus improving the checking efficiency; and the full-functional multiple-meter-position checking device also can be used for carrying out multiple tests on multiple parameters of each voltage monitor.

Description

technical field [0001] The invention relates to a calibration device for a full-function multi-table voltage monitor. Background technique [0002] In order to ensure the power supply reliability of the power grid and further improve the high-quality, safe and reliable power quality, the country has focused on the voltage qualification rate and power quality since 2009; power supply companies all over the country have also taken the voltage qualification rate as a performance assessment for a long time. important indicators. In 2009, the comprehensive voltage pass rate of power grids in all provinces across the country was above 95%, and the voltage pass rate in areas with many voltage monitor installation points reached above 99%. Therefore, various regions are increasing investment in the installation of voltage monitors. The country stipulates that the verification cycle of voltage monitors is 1 year / time for important monitoring points, and 1-3 years / time for general mo...
