Abstract

The invention discloses intelligent isolation switch equipment and an electric energy meter operation state analysis method. An intelligent isolation switch has an electric quantity measurement function, is adjustable in measurement error level, can be matched with electric energy meters with different precision, and can quickly confirm and locate the misalignment condition of the electric energymeters during operation state analysis of the electric energy meters. Automatic detection is achieved, intelligent power grid development is promoted, and intelligent power grid construction is effectively supported; identification and positioning are accurate; the identification time is short; an on-line identification mode is adopted, and manual intervention is not needed; electric energy meterswith different precision can be matched, and the intelligent isolating switch does not need to be replaced when the precision of the electric energy meters is improved subsequently; and the detectederror can be actively reported.

Description

technical field [0001] The invention relates to the technical field of low-voltage power distribution, and more specifically, to an intelligent isolation switch device and a method for analyzing the operating state of an electric energy meter. Background technique [0002] Due to factors such as the quality of the energy meter, the influence of the use environment, and improper use methods, the measurement of the energy meter is inaccurate. In order to detect the measurement inaccuracy of the electric energy meter, the usual practice is that the electric energy meter itself has inaccurate self-detection and self-calibration functions. In this way, if there is no external comparison, the error probability of the electric energy meter inaccurate self-detection is high. Another method is to perform measurement inaccuracy detection on electric energy meters through manual regular or irregular spot checks, which is inefficient and cannot cover all electric energy meters. Conten...
