A device and method for batch testing power control or monitoring metering instruments

Abstract

An apparatus and method for batch testing of electric power controlling or monitoring metering devices are disclosed. The apparatus comprises a PC, a batch testing controller, a signal source generator, an automatic positioning component and a serial server component, wherein the batch testing controller comprises a CPU plug-in, a switching value input function plug-in, a switching value output function plug-in, and a signal function plug-in. The CPU plug-in controls the switching value input function plug-in, the outlet function plug-in and the signal function plug-in connected with the CPU plug-in by receiving commands of the PC, the switching value input function plug-in, the outlet function plug-in and the signal function plug-in are connected with metering devices to be tested through fixing devices to test current, voltage, power factors, switching value input function and switching value output function of the metering devices to be tested. The serial server component receives the test results through a 485 communication interface and feeds back the test results to the PC. The apparatus and method have the advantages of being time-saving and convenient, high in automation level and high in reliability, and are widely applicable to batch production and testing of electric power metering devices.

Description

technical field [0001] The invention relates to the technical field of testing electric power measuring instruments, in particular to a device and method for batch testing electric control or monitoring measuring instruments. Background technique [0002] With the continuous development of my country's electric energy, the power system is developing rapidly in the direction of intelligence and digitization, and the functional requirements for system integration, power parameter collection, power parameter display, and calculation in the power market are increasing day by day. At present, power meters are facing product There are many models, large quantities, cumbersome testing process, and the testing method is limited to a single test of each function through manual methods, resulting in product testing lag, low testing efficiency, and affecting product quality and delivery cycle. Contents of the invention [0003] Aiming at the above problems, the present invention propo...
