Problems solved by technology

[0005] The above-mentioned patent solves some manual operations, but still uses pulse counters for testing. Using pulse counters or power-on and power-on controllers alone in the equipment will disperse the control and require manual processing. The efficiency is low, the function is simple, and the meter cannot be controlled reliability test

Abstract

The invention relates to a pulse test and electric meter power-on and power-off reliability test system which comprises an isolation transformer, an intelligent pulse testing device, a tested intelligent electric meter and a PC terminal. The isolation transformer is connected with the commercial power and is electrically connected with the intelligent pulse testing device. The control output end of the intelligent pulse testing device is connected to the voltage input end of the tested intelligent electric meter, the PC end is connected to the near-infrared output end of the intelligent pulse testing device through a serial port, and the PC end is electrically connected to the near-infrared output end of the tested intelligent electric meter. According to the invention, the pulse counter, the power-on and power-off control and the upper computer are organically combined together to form an integral system for testing the reliability of the ammeter, so that high-efficiency testing work is realized.

Description

technical field [0001] The invention belongs to the technical field of electric measurement, and in particular relates to a system and method for pulse test and electric meter power on and off reliability test. Background technique [0002] Most of the energy meters are used for electricity bill settlement or economic assessment, and they are measuring instruments that are subject to compulsory inspection by the state. The inspection regulations of the state and the power industry stipulate that the newly purchased electric energy meters should be verified for the first time, and the electric energy meters in operation should be regularly verified. , in the face of a large number of tested instruments, especially the sharp increase of various high-performance instruments, higher requirements are put forward for the verification work. The accuracy of electric energy meter measurement is directly related to the interests of both the power supply and the consumer, and directly ...
