[0002] Gas-insulated equipment such as GIS and GIL that use SF6 gas as the insulating medium occupy a core position in modern high-voltage, ultra-high-voltage and other power stations and substations. If a failure occurs, the normal operation of the equipment cannot be restored in time, which seriously affects the power generation efficiency.

In addition, the recovered SF6 gas needs to be routinely inspected individually, which is time-consuming and labor-intensive, inconvenient to work, and delays the progress of the project.

DETAILED DESCRIPTION

[0021] Reference Figure 1-4 The gas recovery and storage device of the utility model includes a frame 1 and a plurality of gas cylinders 5. The plurality of gas cylinders 5 are installed in the frame 1 in a matrix arrangement. The gas recovery and storage device also includes a confluence gas pipe assembly. The confluence gas pipe assembly includes a confluence mother pipe 2 and a plurality of branch gas pipes 3. The branch gas pipes 3 are used to connect the gas cylinders 5 and the confluence mother pipe 2. The confluence mother pipe 2 has two interfaces, one of which is connected to a gas monitoring and analysis machine 6, and the other is used to connect a gas supply device or a gas using device. A filter screen 12 is provided at the two interface positions of the confluence mother pipe 2. The gas supply device or the gas using device here can be the same device or different devices. For example, during the maintenance of GIS and GIL equipment, the SF6 gas therein is recovered into the gas cylinder 5 through one of the interfaces of the confluence mother pipe 2 in advance. Of course, the recovery process can adopt the conventional means in this field to achieve the recovery of SF6 gas into the gas cylinder 5. In the process of recycling, since the main conduit 2 is also connected to the gas monitoring and analysis machine 6, the gas pressure, temperature, humidity and other parameters in the process of recycling gas can be monitored by the gas monitoring and analysis machine 6 to ensure the safe and reliable recycling process. After the maintenance is completed, the interface can be connected to the charging end of the GIS and GI L equipment to complete the charging. Whether it is recycling or charging, since the main conduit 2 is connected to the gas monitoring and analysis machine 6, various parameters can be monitored in real time to ensure the safety and reliability of charging and discharging.

[0022] Among them, refer to Figure 1 , Figure 4 The gas monitoring and analyzing machine 6 includes a processor 61, a display 62, a temperature sensor 63, a pressure density sensor 64 and a humidity sensor 65. The processor 61 is electrically connected to the display 62, the temperature sensor 63, the pressure density sensor 64 and the humidity sensor 65. The temperature sensor 63, the pressure density sensor 64 and the humidity sensor 65 used in this embodiment can all be conventional sensors available on the market to complete temperature, humidity and density detection. Since the sensor itself is not the focus of the utility model and is also a conventional technical means, this embodiment will not be described in detail.

[0023] It should be noted that the gas monitoring and analysis machine 6 also includes an external infrared gas detection sensor 7 for monitoring gas leakage. Other sensors all adopt a built-in structure and are in contact with the gas; while the infrared gas detection sensor 7 adopts an external structure for monitoring leaked gas. Of course, the infrared gas detection sensor 7 also uses the existing technology in this field to complete leakage monitoring. A three-way valve is also provided on the interface of the gas monitoring and analysis machine 6 on the busbar 2, and a barometer 4 is connected through the three-way valve. Through the barometer 4, simple and fast identification can be achieved.

[0024] In the utility model, collision-absorbing pads 8 are arranged between the frame 1 and the gas cylinder 5, and between the gas cylinders 5 and the gas cylinders 5. Shock-absorbing pads are laid on the bottom of the gas cylinders 5. By arranging the collision-absorbing pads 8, the impact force between the gas cylinders 5 and the gas cylinders 5 is reduced; and the shock-absorbing pads at the bottom of the gas cylinders 5 reduce the force of the bottom of the frame 1 on the gas cylinders 5.

[0025] Reference Figure 1 The frame 1 is provided with two layers of cross arm assemblies at the bottom, and the gas cylinder 5 is placed on the upper cross arm assembly. There is a space between the two layers of cross arm assemblies for forklift insertion, and a number of vertical support members are provided in the space. By inserting a forklift into the space between the cross arm assemblies on both sides, the entire gas recovery device can be quickly transported. The vertical support members are made of angle steel. In this embodiment, a total of four groups are provided, and at least two holes are left in the middle to facilitate forklift insertion.

[0026] Reference Figure 3 The frame 1 includes a column located on one side of the frame 1 and a detachable cross arm 11 arranged between the columns. A support block 9 for supporting the cross arm is provided on the column. The support block 9 is provided with an inclined slope portion. The support block 9 is welded to the column, and the slope portion is inclined toward one side of the column. A positioning pin 10 is provided on the detachable cross arm 11. The detachable cross arm 11 is installed on the inner side of the two columns and is clamped on the slope portion of the support block 9 through the positioning pin 10. By designing a detachable cross arm structure, it is convenient to take out and install the gas cylinder 5. When disassembling, you only need to take the detachable cross arm 11 directly from the top, so that a space for taking out and releasing the gas cylinder 5 is formed on one side of the frame 1; if the gas cylinder 5 is installed, the detachable cross arm 11 is directly placed between the two columns. The columns and the detachable cross arm 11 both adopt angle steel structure. The columns generally adopt a right-angle structure facing inward. When the detachable cross arm 11 is placed between the columns, the horizontal inner and outer direction limit is maintained by one of the side surfaces of the columns, so that the detachable cross arm 11 is always on the inside, and then the positioning pin 10 under the detachable cross arm 11 is placed on the inclined portion to achieve horizontal and lateral limit, thereby achieving the installation of the detachable cross arm 11. The installation is convenient, and the gas cylinder 5 can be kept fixed. At the same time, it is also convenient to disassemble.
