Introduction

"Type Evaluation Outline of Installed AC Watt-hour Meter" refers to international recommendations OIMLR46-1/-2.2012 and GB/T 17215 series of national standards, and in accordance with JJF 1016-2014 "Outline of Type Appraisal Outline of Measuring Instruments" Prepared by the requirements of "Guide to Writing." Contains the following 5 parts. ---JJF 1245.1-2019 "Installation type AC energy meter type evaluation outline active energy meter"; ---JJF 1245.2-2019 "Software Requirements for Type Evaluation Outline of Installed AC Energy Meter"; ---JJF 1245.3-2019 "Reactive Reactive Energy Meter for Type Evaluation Outline of Installed AC Energy Meter"; ---JJF 1245.4-2019 "Special Requirements and Safety Requirements for Type Evaluation Outline of Installed AC Energy Meters"; ---JJF 1245.5-2019 "Functional Requirements for Type Evaluation Outline of Installed AC Energy Meter". When using the "Type Evaluation Outline of Installed AC Watt-hour Meter" for the type evaluation test of the AC Watt-hour meter, the According to the characteristics of the energy meter, select the corresponding part of the outline. This series outline replaces the original series outline JJF 1245.1~6-2010, compared with JJF 1245.1~6-2010, The main changes are as follows. ---Adopt a new frame structure. no longer use general requirements-special requirements structure. With international recommendations OIML R46-1/-2.2012 is the main part, adding relevant content of GB/T 17215 series of national standards. JJF 1245.1-2019 And JJF 1245.2-2019 basically covers the content of OIMLR46-1/-2.2012; JJF 1245.3-2019 According to the content of reactive energy meter measurement and technical requirements in the national standard, it is compiled according to the architecture of JJF 1245.1-2019 Write; JJF 1245.4-2019 according to JJF 1245.1-2019 and JJF 1245.3-2019 not covered but national standards Contains the content of measurement and technical requirements and safety-related requirements; JJF 1245.5-2019 in Revised on the basis of JJF 1245.6-2010. --- Added software requirements. JJF 1245.2-2019 refers to international recommendations OIMLR46-1/-2.2012 The content of the quantitative performance protection chapter, combined with the technical characteristics and management requirements of my country's electric energy meter, proposes software requirements for the electric energy meter Seeking, and give the verification method. --- Added and revised measurement and technical requirements. increased durability, higher harmonics, differential mode current interference, electricity Rapid changes in current, ringing wave and other items, modified voltage and current harmonics, constant magnetic field, radio frequency electromagnetic field radiation, electricity Pressure drop and short-term interruption, vibration, sunlight radiation protection, waterproof and other test items.
