Abstract

The invention provides a detection system and method for reliable access of an electric energy meter field calibrator, and the method comprises the steps: a field calibrator is connected to a detection tool, the detection tool is inserted into a first preset position of an intelligent junction box, a first branch is switched on, and a second branch is switched off; main loop current is collected through a first sampling circuit, first branch current is collected through a second sampling circuit, and the main loop current is compared with the first branch current through a processor so as to determine whether the field calibrator is normally connected into a current loop or not; and after the on-site calibration instrument is normally connected to the main loop, the detection tool is continuously inserted into a second preset position in the junction box, so that the field calibrator can detect the electric energy meter. According to the invention, the first sampling circuit and the second sampling circuit are used for collecting the current in the corresponding branches, and then the processor is used for determining whether the field calibrator is accurately connected to the loopor not, thereby facilitating the improvement of the detection precision of the field calibrator, improving the on-site detection efficiency, and eliminating the potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of electric energy meter measurement, in particular to a detection system and method for reliable access of an electric energy meter calibrator. Background technique [0002] The energy meter is a measuring instrument used by electric power enterprises to measure the electricity consumption of electric power users. To ensure the accurate measurement of electric energy meters is to be responsible for electric energy meter users, and it will also be directly related to the economic benefits of related electric power enterprises. With the continuous and rapid development of my country's economy, people's material living standards have been greatly improved, and the demand for electricity is also increasing. Before the new electric energy meter is used or after the old electric energy meter is used, the user must test or recycle it. Generally, the current calibrator is used to measure it. In the prior art, the c...
