Setting value verification device and verification method of multiple voltage monitors

Abstract

The invention discloses a verification device and a verification method for setting values ​​of multiple voltage monitors. It includes a state sequence standard source module, at least two level acquisition modules and a host computer; the state sequence standard source module is connected with at least two voltage monitors and at least two level acquisition modules for providing detection to each voltage monitor The voltage signal is synchronized with the level acquisition module, wherein the voltage value of the detected voltage signal is gradually increased or decreased according to the preset step size; the level acquisition module is connected with the voltage monitor one by one for the acquisition of voltage The alarm signal sent by the monitor determines the time when the alarm signal is sent; the host computer is connected with the level acquisition module and the state sequence standard source module to receive the time when the alarm signal is sent and the detection voltage signal, and according to the time of the received alarm signal and the detection voltage signal to determine the setting value of the voltage monitor. The invention can improve the verification efficiency and precision, and reduce the verification error.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of instrument detection, and in particular to a verification device and a verification method for setting values ​​of multiple voltage monitors. Background technique [0002] In the power system, in order to maintain the reactive power balance of the system and maintain the stability of the system, it is necessary to install a voltage monitor at the voltage monitoring point of the user's power receiving end of each voltage level to monitor whether the voltage value of the user's power receiving end of each level is normal. scope. In order to ensure the accuracy and reliability of the online operation of the power system and the network-connected voltage monitor, power operation and maintenance personnel need to calibrate the voltage monitor to ensure that the voltage monitor can send out an alarm signal in time when the online operation and network-connected voltage are abnormal, prompt...

AI Technical Summary

Problems solved by technology

[0003] At present, there is equipment on the market that can simultaneously verify multiple voltage monitors, but the verification of the setting value of the voltage monitor by this device not only takes a long time, but also leads to low verification efficiency of the voltage monitor, and the upper computer The communication pressure is high, so there is a problem of delay in information transmission, which leads to a larger error in the setting value of the verified voltage monitor than the actual setting value of the voltage monitor
