A gas-filled reactor device

Abstract

This utility model relates to the field of ultra-high voltage power transmission technology. The purpose of this utility model is to provide an inflatable reactor device that solves the problem of difficult storage of the equalizing cover. It includes a reactor mechanism and an inflatable mechanism, with the inflatable mechanism mounted on the reactor mechanism. The reactor mechanism includes a base, a reactor, and an equalizing cover, with both ends of the reactor connected to the base and the equalizing cover, respectively. The inflatable mechanism includes a booster pump, a vent pipe, a valve, and a vacuum pump. The valve is mounted on the vent pipe, and both ends of the vent pipe are connected to the booster pump and the equalizing cover, respectively. Since the equalizing cover is inflatable, when the reactor needs to be tested, air is supplied to the equalizing cover through the booster pump, causing the equalizing cover to expand. After the reactor test is completed, the valve is rotated to release air, causing the equalizing cover to deflate and contract. This makes the equalizing cover easy to store, thus solving the problem of difficult storage of the equalizing cover.

Description

Technical Field

[0001] This utility model relates to the field of ultra-high voltage power transmission technology, and in particular to a gas-filled reactor device. Background Technology

[0002] Ultra-high voltage (UHV) power transmission occupies a core position in the national power grid, effectively transmitting large amounts of electricity to meet the needs of long-distance power transmission. UHV transmission projects enable optimized allocation of energy resources over a wider area, laying a solid technological foundation for the development of global energy interconnection. Equalizing shields are a key high-voltage device in UHV transmission and transformation projects. Installed at AC or DC high voltage levels, they eliminate or reduce tip discharge or corona discharge.

[0003] Most equalization hoods are solid aluminum bodies, which are inconvenient to store. Some equalization hoods only work after being inflated, which is how gas makes the equalization hood bulge. Inflating or deflating the equalization hood is still inconvenient, ultimately making it inconvenient to store. In addition, the hood is bulky when stored, which is also not conducive to transportation. Utility Model Content

[0004] The purpose of this invention is to provide an inflatable reactor device that solves the problem of difficult storage of the equalizing cover.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This invention provides a gas-filled reactor device, including a reactor mechanism and a gas-filling mechanism, wherein the gas-filling mechanism is disposed on the reactor mechanism. The reactor mechanism includes a base, a reactor, and a voltage equalization cover, with the two ends of the reactor connected to the base and the voltage equalization cover, respectively. The inflation mechanism includes a booster pump, an air pipe, an air valve, and a vacuum pump. The air valve is installed on the air pipe. The air outlet of the air pipe is connected to the equalizing hood. The air pipe also has an air inlet and an air extraction end. The booster pump is connected to the air inlet of the air pipe, and the vacuum pump is connected to the air extraction end of the air pipe. The equalizing hood has two states: inflated and deflated.

[0006] Optionally, the reactor is provided with a channel, the base is provided with a groove, the channel is connected to the groove, and the vent pipe is disposed in the channel and the groove.

[0007] Optionally, the reactor mechanism further includes a flange, with two reactors connected to each end of the flange, and the vent pipe passing through the flange.

[0008] Optionally, the vent pipe is located outside the reactor.

[0009] Furthermore, the inflation mechanism also includes a support rod, the two ends of which are respectively connected to the outer wall of the reactor and the vent pipe.

[0010] Optionally, the equalizing cover is an insulating cover, and a metal sheet is provided on the equalizing cover, the metal sheet being electrically connected to the reactor.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model discloses an inflatable reactor device. Since the equalizing cover is inflatable, when the reactor needs to be tested, the vacuum pump first evacuates the equalizing cover, and then the booster pump supplies air into the equalizing cover, causing it to expand and bulge. After the reactor test is completed, the air valve is rotated to release the air, and the equalizing cover deflates and contracts. This makes the equalizing cover easy to store, thus solving the problem of difficult storage of the equalizing cover. Attached Figure Description

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Example 1, as Figure 1 and Figure 2 and Figure 3 As shown, an inflatable reactor device includes a reactor mechanism 1 and an inflatable mechanism 2, with the inflatable mechanism 2 disposed on the reactor mechanism 1.

[0018] The reactor mechanism 1 includes a base 11, a reactor 12, and an equalizing cover 13. The two ends of the reactor 12 are connected to the base 11 and the equalizing cover 13, respectively. The base 11 is set on the test vehicle. When the reactor 12 is vertical, the equalizing cover 13 is located at the top of the reactor 12, and the base 11 is located at the bottom of the reactor 12. The equalizing cover 13 can be detachably fixed to the top of the reactor 12.

[0019] The inflation mechanism 2 includes a booster pump 21, a vent pipe 22, a gas valve 23, and a vacuum pump 25. The gas valve 23 is installed on the vent pipe 22. The outlet end of the vent pipe 22 is connected to the equalizing hood 13. The vent pipe 22 also has an inlet end and a suction end. The booster pump 21 is connected to the inlet end of the vent pipe 22, and the vacuum pump 25 is connected to the suction end of the vent pipe 22. The booster pump 21 is connected to a gas cylinder 3. Before the booster pump 21 supplies gas into the vent pipe 22, the booster pump 21 is turned off, and the gas valve 23 and the vacuum pump 25 are turned on. At this time, the gas in the equalizing hood 13 is evacuated, so that the equalizing hood 13 is in a vacuum state. During the vacuuming process, the gas cylinder 3 and the booster pump 21 will not supply gas into the vent pipe 22.

[0020] Once the equalizing hood 13 is in a vacuum state, the vacuum pump 25 is turned off and the booster pump 21 is turned on. There is dry air in the gas cylinder 3. The booster pump 21 supplies dry air into the vent pipe 22, and the booster pump 25 increases the pressure in the vent pipe 22 until the equalizing hood 13 is full of gas. The equalizing hood 13 has two states: gas filling and gas degassing. The reactor 12 is in the gas filling state during the test and in the gas degassing state after the test is completed.

[0021] Before the reactor 12 is tested, the booster pump 21 and the gas valve 23 are turned on. The booster pump 21 supplies gas to the equalizing hood 13 through the air pipe 22. At this time, the vacuum pump 25 will not leak gas. After the equalizing hood 13 expands and bulges, the gas valve 23 and the booster pump 21 are turned off, so that the inside of the equalizing hood 13 is in a state of full gas.

[0022] After the reactor 12 is tested, open the gas valve 23 to allow the gas in the equalizing cover 13 to be discharged from the vent pipe 22. Then remove the equalizing cover 13 from the reactor 12 for easy storage. In this example, the equalizing cover 13 is fixed to the reactor 12 by a snap-fit.

[0023] The reactor mechanism 1 also includes a flange 17, with two reactors 12 connected to each end of the flange 17. A vent pipe 22 passes through the flange 17. At least two reactors 12 are provided, and two adjacent reactors 12 are connected through the flange 17. The reactors 12 and the flange 17 are fixed together with screws.

[0024] The equalizing cover 13 is an insulating cover. Metal plates 16 are provided on the equalizing cover 13. The metal plates 16 are electrically connected to the reactor 12. Multiple metal plates 16 are provided, and adjacent metal plates 16 are electrically connected to each other, thereby increasing the insulation capacity of the inflatable equalizing cover 13 and preventing high voltage corona.

[0025] like Figure 4 As shown, the reactor 12 is provided with a channel 14, and the base 11 is provided with a groove 15. The channel 14 and the groove 15 are connected. The groove 15 extends on the surface of the base 11. The vent pipe 22 is provided in the channel 14 and the groove 15. The vent pipe 22 is built-in and occupies little space.

[0026] Example 2, as Figure 5 and Figure 6 As shown, unlike Embodiment 1, the vent pipe 22 is located outside the reactor 12. This exposed vent pipe 22 facilitates its disassembly and maintenance.

[0027] The inflation mechanism 2 also includes a support rod 24, with its two ends connected to the outer wall of the reactor 12 and the vent pipe 22, respectively. The two ends of the support rod 24 are connected to the reactor 12 and the vent pipe 22 by snap-fit, so that the support rod 24 and the vent pipe 22 are easy to disassemble and install.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
