Problems solved by technology

[0003] Most of the sulfur hexafluoride density relays installed on the substation site at this stage are GIS equipment bodies directly connected to the sulfur hexafluoride density relay through a three-way joint without valves. The test joints of the three-way joints are made by each manufacturer. There are two problems in this way: ①The calibration or replacement of the sulfur hexafluoride density relay must be disassembled together with the whole meter and the tee joint. The regular calibration workload is heavy and it is easy to cause Gas leakage of GIS equipment; ②Due to the different specifications of the test gas sampling interface used by different manufacturers, it brings inconvenience to the chemical test or gas repair work related to sulfur hexafluoride gas on site

Abstract

The present invention discloses a multi-purpose sulfur hexafluoride gas density relay device. The device comprises a sulfur hexafluoride gas relay SF6, a multi-port adaption piece and a T-shaped three-way valve, the T-shaped three-way valve is detachably connected with the multi-port adaption piece through a C-way of the T-shaped three-way valve, a B-way of the T-shaped three-way valve is connected with the sulfur hexafluoride gas relay SF6, an A-way of the T-shaped three-way valve is a special test port, and the multi-port adaption piece is connected with a GIS device. The multi-purpose sulfur hexafluoride gas density relay device is suitable for various different sulfur hexafluoride electrical device factories to achieve uniform specification of gas supply and gas prevention test jointsand improve the working efficiency of the test and maintenance professional teams.

Description

technical field [0001] The invention relates to the field of connecting devices, in particular to a multipurpose sulfur hexafluoride gas density relay device. Background technique [0002] The sulfur hexafluoride density relay installed on the site does not operate frequently, and after a period of time, it often appears that the action is not flexible or the contact is poor. Sometimes the temperature compensation performance will deteriorate, and when the temperature changes, it will cause indication deviation or Misoperation will endanger the safe operation of the power grid. According to DL / T 259-2012 "Sulfur Hexafluoride Gas Density Relay Calibration Regulations" and "Power Grid Enterprise Safety Production Standardization Specifications and Compliance Rating Standards", point 5.6.7.3 "High-voltage circuit breaker damage risk control" and 5.6.7.4 Relevant requirements of "GIS, HGIS combination electrical damage risk control": "Each closed pressure system is equipped wit...
