Fig. 1 is a schematic structural diagram of an auxiliary device of an extra-high voltage SF6 gas supplementing device according to an embodiment of the utility model. In this fig. 1, the auxiliary device may include a rain shield 10, a base 20, and a connecting pipe 30.
Specifically, the rain-proof cover 10 can be used for being arranged at the top of the SF6 external gas cylinder 40 and preventing rainwater from entering the inside of the SF6 external gas cylinder 40. Wherein, because the gas outlet 41 of the external gas cylinder 40 of SF6 generally sets up near the top of bottle more, consequently can be provided with pipeline channel 11 on this rain-proof cover 10, this pipeline channel 11 can be used for supplying connecting pipe 30 to insert this gas outlet 41 of the external gas cylinder 40 of SF 6.
The base 20 can be used to be arranged at the bottom of the SF6 external gas cylinder 40 and is used to support the SF6 external gas cylinder 40. One end of the connecting pipe 30 can be used for being connected with the air outlet 41 of the external SF6 gas cylinder 40, and the other end of the connecting pipe 30 can be used for being connected with the air inlet of the extra-high voltage SF6 gas supplementing device.
FIG. 2 is a front view of a partial structure of an auxiliary device of an extra-high voltage SF6 gas supplementing device according to an embodiment of the utility model; FIG. 3 is a side view of a part of the structure of an auxiliary device of an extra-high voltage SF6 gas supplementing device according to one embodiment of the utility model. In one embodiment of the utility model, it is contemplated that personnel may need to observe and confirm the gauge reading within the SF6 external gas cylinder 40 during rounds and replacements. In order to facilitate observation of workers, as shown in fig. 2 and 3, an observation window 12 may be provided on the rain cover 10. The observation window 12 may be a position on the rain cover 10 opposite to the instrument panel of the SF6 external gas cylinder 40, so as to facilitate the staff to observe the real-time instrument reading.
In one embodiment of the present invention, in order to further improve the rain-proof and dust-proof effects, rain water or dust is prevented from entering the cavity between the rain-proof cover 10 and the SF6 external gas cylinder 40. As shown in fig. 2, the rain shield 10 may include a sealing ring 13. The sealing ring 13 can be arranged at the inner side of the pipeline channel and the connection position of the bottom of the rain cover 10 and the SF6 external gas cylinder 40.
Fig. 4 is a schematic diagram of a partial structure of an auxiliary device of an extra-high voltage SF6 gas supplementing device according to an embodiment of the utility model. In one embodiment of the present invention, in order to further improve the rain-proof and dust-proof effects of rain-proof cover 10, as shown in fig. 4, rain-proof cover 10 may include a sealing gasket 14. The gasket 14 may be disposed between the rain shield 10 and the SF6 external gas cylinder 40. In addition, because sealed 14 is higher for the holistic thickness of sealing washer 13, consequently when improving rain-proof and dustproof effect, can also establish the one deck isolation layer between rain-proof cover 10 and the external gas cylinder 40 of SF6, avoid the equipment surface damage that leads to because the friction when changing the external gas cylinder 40 of SF 6.
In one embodiment of the present invention, the SF6 external cylinder 40 is maintained at a level required for gas filling to facilitate gas output. Thus, as shown in FIG. 5, the base 20 may include a level 21. The level gauge 21 may be disposed on the top surface of the base 20 for determining whether the base 20 is in a horizontal state. When the SF6 external gas cylinder 40 is replaced, a worker can determine whether the current SF6 external gas cylinder 40 is installed correctly through the level 21. Further, in order to facilitate the staff to adjust the levelness of the SF6 external air cylinder 40, the bottom of the base 20 may be provided with a horizontal adjusting mechanism 22. Through this horizontal adjustment mechanism 22 staff just can directly adjust the levelness of the external gas cylinder 40 of SF6, has simplified the installation operation to the efficiency of installation has been improved.
In one embodiment of the utility model, the base 20 may include a scale 23 in order to enable remote determination of the remaining amount of SF6 gas in an SF6 external gas cylinder 40. The weighing instrument 23 can be arranged on the base 20 for supporting the SF6 external gas cylinder 40 and measuring the mass of the SF6 external gas cylinder 40, so as to obtain the residual amount of SF6 gas through conversion. Although the camera is arranged at the observation window 12 of the rain-proof cover 10 to directly collect the meter reading, the residual amount of the SF6 gas can be directly obtained, the SF6 external gas cylinder 40 is placed in the external environment, dust is easily generated on the observation window 12, and the collection of images is affected. On the other hand, the camera itself is also more costly and relatively less durable, so the remaining amount of SF6 gas can be better obtained with the weighing scale 23.
Since the SF6 gas is in a liquid state in the SF6 external gas cylinder 40, the SF6 gas is gradually gasified due to the reduction of the gas pressure after the SF external gas cylinder 40 is opened at the normal temperature. However, when the temperature of the external environment is low, the time for gasifying SF6 gas is prolonged, thereby limiting the efficiency of gas supply. Therefore, in one embodiment of the present invention, to ensure the gas supply efficiency of SF6 gas in a low temperature environment, the base 20 may include a heated outer layer 24. The heating outer layer 24 can be used for heating the SF6 external gas cylinder 40. Further, in order to further enhance the heating effect, the base 20 may include an insulation layer 25. The insulation layer 25 may be disposed on the outside of the heating outer layer 24 to provide insulation. Furthermore, in order to avoid rainwater entering between the heating outer layer 24 and the SF6 external air cylinder 40, a rainproof baffle 26 can be arranged at the joint of the top of the heating outer layer 24 and the SF6 external air cylinder 40 as shown in fig. 5. This rain-proof baffle 26 can avoid the rainwater to get into between heating outer layer 24 and the external gas cylinder 40 of SF6 to guarantee the steady operation of heating outer layer 24.
On the other hand, the utility model also provides an SF6 external gas cylinder of the extra-high voltage SF6 gas supplementing device, wherein the SF6 external gas cylinder comprises an SF6 external gas cylinder body and any one of the auxiliary devices.
Through the technical scheme, the external SF6 gas cylinder and the auxiliary device thereof of the extra-high voltage SF6 gas supplementing device enable the external SF6 gas cylinder to work stably by externally arranging the SF6 gas cylinder and arranging the auxiliary device comprising a rain-proof cover, a base and the like. The external SF6 gas cylinder and the auxiliary device thereof overcome the technical problem that the SF6 gas cylinder of the gas supplementing device in the prior art is inconvenient to replace, and improve the gas supplementing efficiency and the replacing efficiency of the SF6 gas cylinder.
