Abstract

The present invention disclosed a kind of pair SF 6 The intelligent verification instrument comprehensive judgment of the life cycle of density relay, including the bottom plate and the inspection device body, which is provided with a bracket on both sides of the upper end of the bottom plate.The installation settings are located on the side of the bottom plate near the bottom plate, and the upper end of the bracket has the first adjustment rod through the threaded activity through the activity of the activity.The upper end has a resettlement structure through a limit rotation. The symmetrical settings on both sides of the bottom plate are set with supporting parts with lifting adjustment.The position of the laboratory of the middle school of the present invention is easy to adjust the activity, and the resettlement structure used for resetting the product can be transferred to the limit settings, so that the convenience of the detection can be improved;, And can obtain higher stability and improve the effect of use.

Description

technical field [0001] The invention relates to the technical field of calibrator, in particular to a 6 An intelligent calibrator for comprehensive evaluation of the life cycle of density relays. Background technique [0002] Substation plays the role of "energy transmission artery" in economic and social development, and its importance is self-evident. As a colorless, odorless, non-toxic and non-combustible gas arc extinguishing medium, SF6 has been widely used in electrical equipment, replacing traditional oil medium arc extinguishing electrical equipment, and has been widely used in power grids. [0003] But SF 6 SF often occurs in electrical equipment during daily operation 6 Gas leakage defects, the leakage point mainly appears on the flange surface or SF 6 density relay. The commonly used leak detection method today is to use SF after a certain period of time after sealing the leak point. 6 Probe into the halogen gas detector or directly use the foam detection me...
