Embodiment 1

[0037] Such as figure 1 shown, for SF 6 The monitoring module of the inflation and recovery device includes a gas pipeline, and the two ends of the gas pipeline are respectively provided with a GIS interface and a recovery equipment interface. The chamber is connected, and the recovery device interface is located at the right end of the gas pipeline, and is connected to the recovery device 12 through the second manual valve 11 .

[0038] A first pressure sensor 3, a filter 4, a first solenoid valve 5, a flow meter 6, a calibration container 7 and a calibration container pressure set on the calibration container 7 are arranged in sequence from left to right between the GIS interface 2 and the recovery device 12 The detection structure, the second solenoid valve 9 and the third pressure sensor 10, the above-mentioned components are all prior art, the specific structure of each component will not be described here, and only the specific function and working state of each compone...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, a calibration container 7 is provided on the right side of the flow meter 6, and the flow rate and the deviation correction coefficient can be calculated by the flow rate of the flow meter 6 and the pressure value of the calibration container 7 , to realize the correction of the flow meter 6 in the gas recovery operation. And in this embodiment, if figure 2As shown, a calibration container 7 is added between the flow meter 6 and the first electromagnetic valve 5. In the same way as in Embodiment 1, the flow meter 6 can be adjusted in the gas flow through the flow meter 6 and the calibration container 7 on the left side of the flow meter 6. Correction during inflation operation. At this time, both the first solenoid valve 5 and the second solenoid valve 9 are valves located downstream of the flow meter 6 in use.

[0052] Of course, in other embodiments, the calibration container 7 can als...

Embodiment 3

[0054] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the calibration container detection structure is directly installed on the calibration container 7 . In this embodiment, however, the calibration container detection structure is arranged between the calibration container 7 and the second solenoid valve 9 , and the calibration container detection structure communicates with the flow meter 6 through the gas pipeline.

Abstract

The invention relates to the technical field of real-time gas monitoring during GIS inflation and deflation, in particular to a monitoring module for an SF6 inflation and deflation recovery device and a flowmeter deviation rectifying method, and the monitoring module for the SF6 inflation and deflation recovery device comprises a gas pipeline. The gas pipeline is provided with a GIS interface used for being connected with a GIS and a gas recovery device interface used for being communicated with a gas recovery device, and the gas pipeline is sequentially provided with a flow meter used for monitoring gas flow in the gas pipeline, a calibration container used for storing gas and a valve in the gas flowing direction. The valve is used for being closed at the initial stage of gas flowing and being opened after deviation correction of the flow meter, the calibration container is a container with the constant volume, and a calibration container pressure detection structure used for detecting the internal pressure of the calibration container is further arranged on the gas pipeline.

Description

technical field [0001] The invention relates to the technical field of gas real-time monitoring when GIS is inflated and deflated, in particular to 6 The monitoring module of the inflation and deflation recovery device and the deviation correction method of the flowmeter. Background technique [0002] With the development and application of technologies such as intelligent manufacturing and the Internet of Things, the traditional manufacturing industry has gradually shifted from mechanization, electrification, and digitalization to networked, digital, and intelligent manufacturing. The intelligent demand for recycling device products is also gradually increasing. With the promotion of ubiquitous power Internet of Things construction, new requirements have been put forward for equipment operation management, status monitoring, and data transmission of recovery devices, and existing equipment (such as oil purifiers, SF 6 Intelligent transformation of gas recovery device). ...
