Abstract

The invention discloses a method for detecting power-failure counting function of distribution transformer terminals in batch, which comprises the following steps of: 1, connecting voltage and current lines to a plurality of distribution transformer terminals to be detected, and hanging on a meter hanging frame; 2, setting the communication connection of the terminals to be detected and a PC; 3, setting the connection mode, and voltage and current basic parameters of the terminals to be detected through the PC; 4, setting or calling the pre-stored test scheme through PC software; 5, sending commands to the distribution transformer terminals to be detected and a source table control cabinet by using the PC, outputting various voltage environments, and testing the distribution transformer terminals to be detected; and 6, reading voltage and current values of a standard table through a serial port and sequentially calculating real voltage monitoring data by using the PC, and comparing the voltage monitoring data of the terminals read by the PC through the network with the voltage monitoring data values of the standard table to obtain a conclusion. The method solves the problems that the conventional detection method has troublesome indoor detection process, too long actual detection time, high workload and the like, and has the advantages of high efficiency of production test, accurate and reliable test results and the like.

Description

technical field [0001] The invention relates to the testing field of power failure monitoring and statistical functions of distribution transformer terminals, and provides a method for batch detection of power failure statistical functions of distribution transformer terminals. Background technique [0002] Whether the power outage statistics function of the distribution transformer terminal equipment is qualified or not needs to be tested. The existing detection method is mainly to artificially manufacture the power outage event of the distribution transformer terminal, wait for the corresponding time, and then check the records of the distribution transformer terminal on site or use the master station program to call and read individually The data recorded by the transformer terminal is used for comparison and detection. The details are as follows, hang the distribution transformer terminal in the power consumption environment, then artificially cut off the power to cause ...
