Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a device for removing moisture from insulating gas in switchgear. Background Technology

[0002] The switchgear insulating gas dehydration device is a moisture treatment device specifically designed for insulating gases inside switchgear. It is mainly used to solve the problem of excessive moisture content in insulating gases and to avoid potential hazards such as reduced gas insulation performance, corrosion of internal metal parts, or condensation at low temperatures caused by moisture.

[0003] However, some traditional dewatering devices lack sufficient sealing and are difficult to effectively isolate from the outside air, causing air to easily mix into the insulating gas during the dewatering operation, which damages the gas purity and weakens its insulation performance. On the other hand, some condensation dewatering devices lack an efficient condensate drainage mechanism, causing the generated condensate to continuously adhere to the inner wall of the device, which can then easily re-integrate into the insulating gas with the gas circulation, causing the moisture content to exceed the standard again. Utility Model Content

[0004] The purpose of this invention is to effectively prevent insulating gas from mixing with external air during the dehydration process, thereby preventing air impurities from affecting gas purity and ultimately ensuring stable insulating gas purity. This invention provides a dehydration device for switchgear insulating gas, solving the problems of traditional devices being unable to effectively isolate air and lacking an effective condensate drainage structure.

The length of the heating plates is less than the length of the dehydration tank and they are staggered inside the dehydration tank.

[0009] According to the switchgear insulating gas dehydration device of this utility model, an electromagnetic valve is fixedly connected inside the partition plate, and the electromagnetic valve is used to connect the upper and lower parts of the partition plate.

[0010] According to the switchgear insulating gas dehydration device of this utility model, a condensing plate is fixedly connected to the lower side of the dehydration tank.

[0013] Beneficial effects:

[0014] 1. The switchgear insulating gas dehydration device of this technical solution forms an air path isolation by sliding the first push plate along the horizontal guide shaft and the second push plate along the vertical guide shaft. Combined with the water seal in the U-shaped drain pipe to block the entry of external air, and the precise control of the air path connection between the upper and lower parts of the dehydration tank by the solenoid valve, it can effectively prevent the insulating gas from mixing with the external air during the dehydration process, thereby preventing air impurities from entering and affecting the purity of the gas. Ultimately, it ensures the stability of the insulating gas purity and ensures that the insulation performance of the equipment in the switchgear is not affected.

[0015] 2. Vibration is generated by the vibrator, which causes the water droplets on the condenser plate to flow to the bottom of the water removal tank. The water droplets are then discharged through the U-shaped drain pipe using the principle of communicating vessels, achieving efficient separation and discharge of condensate. This reduces the possibility of the insulating gas re-contacting the water droplets, which would otherwise cause the moisture content to increase. This significantly improves the water removal efficiency and ensures stable gas pressure after the insulating gas is recharged into the switchgear. Attached Figure Description

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 The present invention relates to a switchgear insulating gas dehydration device, which includes a base 1, a dehydration tank 9 fixedly connected to the upper part of the base 1, four horizontal guide shafts 21 fixedly connected to the lower part of the dehydration tank 9, a first push plate 14 slidably connected to the middle of the horizontal guide shafts 21, four vertical guide shafts 17 fixedly connected to the upper part of the dehydration tank 9, a second push plate 18 slidably connected to the middle of the vertical guide shafts 17, and two U-shaped drain pipes 13 fixed at the bottom of the dehydration tank 9.

[0025] Specifically, the insulating gas is input into the dehydration tank 9, which pushes the first push plate 14 to slide to the other side along the horizontal guide shaft 21. After the insulating gas is dehydrated, it enters the upper part of the dehydration tank 9 and pushes the second push plate 18 to move upward along the vertical guide shaft 17. With the help of the first push plate 14 and the second push plate 18, air can be isolated to ensure the purity of the insulating gas. The U-shaped drain pipe 13 at the bottom contains a certain amount of water. The condensed water flows to the U-shaped drain pipe 13 and flows out of the dehydration tank 9 through the principle of communicating vessels. The U-shaped drain pipe 13 can prevent the insulating gas from contacting the outside air and at the same time discharge the condensed water, reducing the impact of the insulating gas re-contacting water droplets on the moisture content.

[0026] A vent pipe 3 is fixedly connected to the lower part of one side of the water tank 9. A first valve 5 is fixedly connected to the middle of the vent pipe 3. A first air pump 4 is fixedly connected to the middle of the vent pipe 3. An air inlet pipe 6 is fixedly connected to the upper part of one side of the water tank 9. A second valve 8 is fixedly connected to the middle of the air inlet pipe 6. A switch cabinet 2 is fixedly connected to the other end of the vent pipe 3.

[0027] Specifically, during maintenance, the first valve 5 is opened and the first air pump 4 is started. The insulating gas in the switch cabinet 2 is pumped into the dewatering tank 9 through the exhaust pipe 3. After the insulating gas has been dewatered, the second valve 8 is opened, and the insulating gas is discharged into the switch cabinet 2 under the action of the second push plate 18.

[0028] A first cylinder 10 is fixedly connected to the top of the water tank 9, and a first telescopic rod 15 is slidably connected inside the first cylinder 10. A second cylinder 11 is fixedly connected to the other side of the water tank 9, and a second telescopic rod 22 is slidably connected inside the second cylinder 11. Multiple vent holes 7 are provided on the top and the lower part of the other side of the water tank 9.

[0029] Specifically, the first cylinder 10 pushes the first telescopic rod 15 to move, which in turn pushes the second push plate 18 to move downward, pressing the insulating gas into the switch cabinet 2; the second cylinder 11 pushes the second telescopic rod 22 to move, which in turn pushes the first push plate 14 to move, pressing the insulating gas into the upper part of the dewatering tank 9.

[0030] Multiple heating plates 16 are fixedly connected to the upper side of the water removal tank 9, and a partition plate 19 is fixedly connected to the middle of the water removal tank 9. The length of the heating plates 16 is less than the length of the water removal tank 9, and they are staggered inside the water removal tank 9.

[0031] Specifically, the heating plate 16 can heat the condensed low-temperature insulating gas to room temperature, preventing the low-temperature gas from entering the switch cabinet 2 and causing pressure changes after returning to room temperature, thus affecting normal use; the partition plate 19 can divide the water tank 9 into upper and lower boxes.

[0032] A solenoid valve 20 is fixedly connected inside the partition plate 19. The solenoid valve 20 is used to connect the upper and lower parts of the partition plate 19.

[0033] Specifically, the solenoid valve 20 is used to control the flow of insulating gas between the upper and lower parts of the dewatering tank 9.

[0034] A condenser plate 23 is fixedly connected to the lower side of the inside of the water removal tank 9. The height of the condenser plate 23 is less than half the height of the water removal tank 9, and it is staggered inside the water removal tank 9.

[0035] Specifically, the condenser plate 23 is used to cool the insulating gas, causing the water vapor in it to condense into water droplets.

[0036] A vibratory machine housing 12 is fixedly connected to one side of the water tank 9. A bidirectional motor 24 is fixedly connected inside the vibratory machine housing 12. A drive rod 25 is rotatably connected to the bidirectional motor 24. An eccentric block 26 is fixedly connected to both ends of the drive rod 25.

[0037] Specifically, the bidirectional motor 24 drives the drive rod 25 to rotate, and the drive rod 25 drives the eccentric block 26 to rotate, thereby generating vibration.

[0038] Two metal shafts 28 are fixedly connected inside the vibratory machine housing 12. The metal shafts 28 are slidably connected to the bidirectional motor 24. Two springs 27 are sleeved on the outside of the metal shafts 28. The two ends of the springs 27 are fixedly connected to the inner wall of the vibratory machine housing 12 and the bidirectional motor 24, respectively.

[0039] Specifically, when the bidirectional motor 24 slides along the metal shaft 28, it is pulled back by the spring 27, causing the vibrator housing 12 to vibrate; under the vibration of the vibrator housing 12, the water droplets on the condenser plate 23 flow to the bottom.

[0040] Working principle: During switchgear maintenance, ensure that the first cylinder 10 and the second cylinder 11 are in the retracted state, open the first valve 5, and start the first air pump 4. The insulating gas inside the switchgear body 2 is pumped into the lower part of the dewatering tank 9 through the exhaust pipe 3. The gas pushes the first push plate 14 to slide along the transverse guide shaft 21, and the air inside the dewatering tank 9 is discharged from the exhaust port 7. The insulating gas entering the lower part of the dewatering tank 9 is cooled by the action of the condensing plate 23, and the water vapor condenses into water droplets. At the same time, the bidirectional motor 24 is started. The bidirectional motor 24 inside the vibrator housing 12 drives the drive rod 25 and the eccentric block 26 to rotate and generate vibration. When the bidirectional motor 24 slides along the metal shaft 28, it is pulled back by the spring 27, causing the vibrator housing 12 to vibrate. This causes the water droplets on the condensing plate 23 to flow to the bottom and finally through the U-shaped drain pipe at the bottom of the dewatering tank 9. 13. Water is discharged using the principle of communicating vessels. The water in the U-shaped drain pipe 13 prevents the insulating gas from contacting the outside air. After the water is removed, the solenoid valve 20 is opened, and the second cylinder 11 is started. The second cylinder 11 pushes the second telescopic rod 22 to move the first push plate 14, and the insulating gas enters the upper part of the dewatering tank 9. At this time, the insulating gas pushes the second push plate 18 to move upward along the vertical guide shaft 17. The first push plate 14 and the second push plate 18 together isolate the air to ensure the purity of the gas. The gas entering the upper part is heated to room temperature by the heating plate 16 to avoid the low temperature gas affecting the gas pressure inside the circuit breaker of the switch cabinet 2. Finally, the first cylinder 10 is started, and the second valve 8 is opened at the same time. The first cylinder 10 pushes the first telescopic rod 15 to move the second push plate 18 downward, and the insulating gas enters the switch cabinet 2 through the air inlet pipe 6.
