Introduction

JJF 1001 "General Measurement Terms and Definitions", JJF 1059 "Measurement Uncertainty Evaluation and Representation" The basic series of specifications formulated in this outline. The requirements and methods of the test items in this outline refer to JJG1073-2011 "Pressure Type SF6 Gas Density The content of "Controller" and GB/T 22065-2008 "Pressure Type SF6 Gas Density Controller" requires It can objectively, comprehensively and effectively evaluate the performance of the pressure type sulfur hexafluoride gas density controller. The structure of this outline is arranged in accordance with JJF 1016-2014 "Guidelines for the Compilation of Outlines for Measuring Apparatus Type Evaluation". Each chapter is prepared in accordance with the provisions of JJF 1015-2014 "General Specification for Type Evaluation of Measuring Instruments". This outline is published for the first time. Pressure type SF6 gas density Controller type evaluation outline

1 Scope

This outline applies to the classification code of measuring instruments is 12320000, with spring tube or bellows as the measuring element, measuring The volume range is (-0.1 ~ 0.9) MPa or (-0.1 ~ 0.5) MPa, the nominal diameter of the instrument shell is 100mm, The pressure type sulfur hexafluoride (SF6) gas density controller (or gas density relay) whose working medium is sulfur hexafluoride gas Type evaluation of electrical appliances, gas density monitors, hereinafter referred to as "controller").

3 Terminology

3.1 Rated pressure ratingpressure Under standard atmospheric pressure conditions, before the equipment is put into operation or when supplementing gas, fill the equipment gas chamber with SF6 as required The pressure of the gas. [JJG1073-2011 Terms and Definitions 3.1] 3.2 Alarm pressure When the pressure of SF6 gas in the equipment gas chamber drops to a certain set value, the controller will send out an alarm signal. The set value is called the alarm pressure. Note. Rewritten from JJG1073-2011 Terms and Definitions 3.2. 3.3 Locking pressure atresiapressure When the pressure of SF6 gas in the equipment gas chamber drops to a certain set value, the controller will send a blocking signal. The fixed value is called blocking pressure.
