Novel SF6 gas splitter

Abstract

The invention relates to a novel SF6 gas splitter which is characterized in that the novel SF6 gas splitter comprises a sixth three-way valve and a first four-way valve, a first outlet of the sixth three-way valve is communicated with a first inlet of the first four-way valve, a first inlet of the sixth three-way valve is communicated with a gas inlet connector after sequentially passing through a first check valve, a first pressure meter and a first three-way valve, and a second inlet of the sixth three-way valve is communicated with a gas bottle connector after sequentially passing through a second check valve, a second pressure meter and a second three-way valve; a first outlet of the first four-way valve is communicated with a first instrument connector after sequentially passing through a third check valve, a third three-way valve and a third pressure meter, and a second outlet of the first four-way valve is communicated with a second instrument connector after sequentially passing through a fourth check valve, a fourth three-way valve and a fourth pressure meter. The novel SF6 gas splitter can achieve brackish water, purity and a product decomposing test at the same time and can flexible achieve the purpose that three instruments conduct the comparison test at the same time.

Description

technical field [0001] The invention relates to a novel SF6 gas splitting device. Background technique [0002] SF6 gas moisture, purity, and decomposition product testing are routine test items for SF6 equipment, and are also test items for hidden danger investigation, peak summer, special inspection, and abnormal equipment tracking. "Q / GDW168-2008 Condition Maintenance Test Regulations" Ningxia Electric Power Company's Preventive Test Regulations (2010 Edition) have made specific requirements for micro-water, purity, and decomposition product testing, but there are many heavy testing tasks, and the traditional test of micro-water, purity, and decomposition product testing is carried out in turn. The method has obviously lagged behind and the efficiency is not high. Firstly, multi-equipment testing takes a long time; the testing of SF6 micro-water, purity, and decomposition products in a substation takes more than ten or even dozens of hours; secondly, due to the long test...

[0002] SF6 gas micro-water, purity, and decomposition product tests are routine test items for SF6 equipment, and are also test items for hidden danger investigation, peak summer, special inspection, and abnormal equipment tracking. "Q / GDW168-2008 Condition Maintenance Test Procedure" and Ningxia Electric Power Company's Preventive Test Regulations (2010 Edition) have made specific requirements for micro-water, purity, and decomposition product testing, but there are many heavy testing tasks, and the traditional test of micro-water, purity, and decomposition product testing is carried out in turn. The method has obviously lagged behind and the efficiency is not high

Firstly, multi-device testing takes a long time; the testing of SF6 micro-water, purity, and decomposition products in a substation takes more than ten or even dozens of hours; secondly, due to the long test time, the test conditions - especially the temperature - have changed during the comparative experiment , so that the comparison of the test results is greatly reduced; in addition, the different degrees of dryness of the test pipelines also affect the accuracy of the SF6 test results
