Embodiment Construction
[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0040] A method for inspecting the state of an electric energy meter. The method for inspecting the state of an electric energy meter is based on the operating state of the electric energy meter, comprehensively considering key elements such as the operating stability, operational reliability, and potential defects of the electric energy meter, and reasonably carrying out data mining, model calculation, Status inspection, and formulate inspection strategies based on status inspection results.
[0041] The specific steps are:
[0042] ⑴Inspect the trigger, and the ways to inspect the trigger include:
[0043] ①Family defect trigger, when a problem is found during home use, the user initiates the fami...

The invention relates to an electric energy meter state inspection method. According to the electric energy meter state inspection method, data mining, model calculation and state inspection are reasonably performed on an electric energy meter based on the operating state of the electric energy meter and with the operational stability, operational reliability and potential defects of the electric energy meter comprehensively considered, and inspection strategies are formulated according to state inspection results; the electric energy metering device state evaluation method is put forward for the first time; an electric energy meter operating management mode is improved to state inspection from period inspection, and therefore, manpower and material resources required by period on-site inspection can be greatly saved; and electric energy meter state inspection can become a new strategy for intelligent management of electric energy metering devices in the future under fast development of intelligent power grids.
Description
technical field [0001] The invention belongs to the field of electric field experiments, in particular to a method for checking the state of an electric energy meter. Background technique [0002] At present, the electronic energy meter has been widely used. Unlike the mechanical energy meter, the measurement error of the electronic energy meter is more stable within the verification period. State Grid Corporation of China has implemented the whole-process quality supervision and management of electronic energy meters, covering the whole process before bidding, before delivery, after arrival, during operation and out of operation, providing a prerequisite for the implementation of status inspection and tracking evaluation of energy meters . [0003] However, the current on-site inspection of electric energy meters is mainly carried out in accordance with DL / T448-2000 "Technical Management Regulations for Electric Energy Metering Devices" and relies on technicians to regular...
