Abstract

The invention provides a method for automatically calibrating a terminal in batch, which comprises the following steps: (A) physically setting, connecting the current of all phases of a terminal and the current of relevant phases of a standard meter and a power source in series and connecting the voltage of all phases and the voltages of relevant phases of the standard meter and the power source in parallel; (B) setting configuration and correspondingly configuring the terminal, the standard meter and the power source; (C) establishing serial port connection and connecting a working platform, the terminal, the standard meter and the power source; (D) calibrating the working platform, the calibration comprises data initialization in the zero step, gain calibration in the first step, phase calibration I in the second step, phase calibration II in the third step, phase calibration III in the fourth step and voltage and current calibration in the fifth step; (E) carrying out error detection; and (F) forming a test report.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method for automatically calibrating terminals in batches. Background technique [0002] In the power system, all kinds of negative control terminals, distribution transformer terminals and low-voltage centralized reading terminals need to verify their measurement accuracy errors before they are connected to the network. The calibration method is related to whether the terminal’s measurement is accurate, and the calibration time is related to whether it can Increase productivity. At present, most of the calibration methods are manual calibration methods, which not only take a long time, but also cannot guarantee the comprehensiveness of the calibration and the stability of the product. The ATT chip has just been applied to the negative control terminal and distribution terminal and low voltage The efficiency of manual calibration in the collection terminal is low, and it cannot b...
