Technical Field
[0001] The invention relates to the technical field of ring network cabinets, and in particular to an environmentally friendly outdoor ring network cabinet. Background Art
[0002] The environmentally friendly outdoor ring network cabinet mainly seals the high-voltage live body mechanism completely in the main box, which is not affected by condensation and external dirty environment. The protection level can reach IP67 to ensure the safety and reliability of the equipment. Then, a suitable amount of helium is filled in the cavity as an insulating medium. This gas has good stability and meets environmental protection requirements at the same time, reducing the impact on the environment and ensuring that the outdoor ring network cabinet can better realize the environmental protection function.
[0003] Among the existing technical documents that have been published, the invention patent with Chinese patent publication number CN105071277A discloses an environmentally friendly pneumatic ring network cabinet, in which the busbar connector of the ring network cabinet mainly passes through the busbar through-wall insulating sleeve, and the circuit breaker of the sealed box is located below the three-position disconnector, and an insulating partition is arranged between the circuit breakers. The circuit breaker is controlled by the circuit breaker operating mechanism, and the circuit breaker operating mechanism is located below the three-position disconnector operating mechanism in the cabinet, and a pressure relief device is arranged at the bottom of the sealed box. The invention has the positive effects of safety, reliability, environmental protection and energy saving. However, the ring network cabinet still has the following defects during use.
[0004] During the outdoor use of the ring network cabinet, due to the influence of the outdoor environment, the sealing aging of the connection parts of the air filling box is very likely to occur during long-term use, which will cause the protective gas to leak. It is necessary to wait for maintenance personnel to arrive at the site to check the outer position of the cabinet and the top surface of the cabinet to find the leaking part and then seal the leaking part. However, it takes a long time for maintenance personnel to arrive at the site, and the amount of protective gas leakage is large. It is difficult to automatically detect the leaking part in time and automatically replenish the protective gas to avoid long-term leakage of protective gas, which causes waste of resources. The environmental protection performance of the ring network cabinet is poor. For this reason, an environmentally friendly outdoor ring network cabinet is needed. Summary of the invention

[0009] When the present technical solution is in use, the driving motor drives the screw to rotate, the socket block moves up along the inner wall of the socket frame, and the socket rectangular plate drives the two plugging airbags to move up. The two plugging airbags move up along the outer wall of the environmental protection gas cabinet. The circulating fan can generate suction in the connecting pipe, and the connecting pipe sucks in the air in the gap surrounded by the socket rectangular plate and the two plugging airbags, detects it through the first helium detector, and continues to enter the gap surrounded by the socket rectangular plate and the two plugging airbags. The location of helium leakage outside the environmental protection gas cabinet is quickly detected. When the first helium detector detects helium, it is known that there is a helium leakage site in the gap surrounded by the socket rectangular plate and the two plugging airbags. The controller immediately turns off the drive motor. At this time, the two sealing airbags and the sleeve rectangular plate can be located at the helium leakage site outside the environmental protection gas cabinet. The inflation pump enables the air intake valve to pressurize the external air into the inside of the boosting pipe, and then enters the inside of the two sealing airbags through the boosting pipe.

[0011] When the technical solution is in use, the transmission motor drives the transmission screw to rotate, and the transmission screw carries the threaded sleeve to move left under the action of the thread transmission force, and the threaded sleeve drives the sleeve sealing plate to move left, and the rectangular airbag fits on the upper surface of multiple environmental protection gas cabinets to move left. The detection fan generates suction in the suction pipe, and the air enters the detection fan along the suction pipe, enters the guide pipe through the second helium detector, and continues to circulate from the guide pipe to the space surrounded by the rectangular airbag and the sleeve sealing plate. When the second helium detector detects helium, the transmission motor is turned off by the controller, and the rectangular airbag and the sleeve sealing plate can be located at the helium leakage position at the top of the environmental protection gas cabinet. External pressurized air enters the delivery pipe, and enters the rectangular airbag through the delivery pipe. The rectangular airbag can be expanded and squeezed at the top position of multiple environmental protection gas cabinets. The sleeve sealing plate and the rectangular airbag can completely seal the top position of the environmental protection gas cabinet to prevent continuous leakage of helium at the top of the environmental protection gas cabinet.
[0012] Preferably, the supplementary assembly comprises a helium storage bottle mounted on one side of the circulation pipe;

[0014] When the technical solution is in use, the controller starts to open the top valve, and the controller opens the peripheral valve, and the booster pump pressurizes the helium inside the helium storage bottle and enters the delivery hose. Since the top valve and the sleeve sealing plate are in a fixed connection state, the pressurized helium can enter the gap surrounded by the sleeve sealing plate and the rectangular airbag, and replenish helium at the helium leakage part on the top of the environmental protection gas cabinet, and continue to perform sealing protection. At the same time, the supplementary helium inside the delivery hose can also enter the inside of the connecting hose, and enter the gap surrounded by the sleeve rectangular plate and the two blocking airbags through the peripheral valve. Helium can perform a supplementary operation on the helium leakage part outside the environmental protection gas cabinet. After replenishment, when the pressure value of the pressure transmitter is the pressure value set by the controller, the controller immediately closes the top valve and the peripheral valve.

[0018] 3. The present invention sets a replenishing component, starts to open the top valve through the controller, and opens the peripheral valve through the controller. The booster pump pressurizes the helium inside the helium storage bottle and enters the delivery hose. The pressurized helium can enter the gap surrounded by the sleeve sealing plate and the rectangular airbag, and replenish helium at the helium leakage part on the top of the environmental protection gas cabinet. The helium can be replenished into the gap surrounded by the environmental protection gas cabinet and the inflation sleeve.

The helium storage bottle 40 is made of stainless steel and is used to store helium.
[0042] The use process of the environmentally friendly outdoor ring network cabinet of the present invention is as follows:
[0043] Step 1: When wiring, place the outdoor cover 16 outdoors. The outdoor cover 16 can prevent dust and rain for multiple cabinets 1, and the pressure transmitter 19 is turned forward. The thread between the pressure transmitter 19 and the detection tube 18 is separated, and helium can be flushed into the detection tube 18. The helium enters the space formed between the inflatable sleeve 17 and the environmental protection gas cabinet 2 through the detection tube 18, thereby forming an inflatable protection operation between the environmental protection gas cabinet 2 and the inflatable sleeve 17. After filling with helium, the pressure transmitter 19 and the detection tube 18 are locked forward to complete the docking operation. As a gas with good environmental performance, helium is less likely to pollute the environment. Then connect the connecting wire head 25 to the mains harness, and the bottom of the contact terminal 21 is docked with the upper device connection harness, so that the controller 20 drives the switching motor 24, so that the switching motor 24 drives the rotating shaft 23 to rotate, and the rotating shaft 23 can drive multiple power-off terminals 22 to rotate downward, and the power-off terminals 22 and the contact terminals 21 are docked to close the switch, thereby forming a path for power supply.
[0044] At the same time, the pressure transmitter 19 detects the gas pressure inside the detection tube 18. Since the detection tube 18 is connected to the inflatable sleeve 17, the pressure transmitter 19 can detect the helium pressure between the inflatable sleeve 17 and the environmental protection gas cabinet 2. When the helium pressure value detected by the pressure transmitter 19 is lower than the pressure value set by the controller 20, it is known that there is a helium leakage problem in the environmental protection gas cabinet 2, and the drive motor 5 can be immediately started through the controller 20.
[0045] Step 2: During the peripheral detection and blocking, the drive motor 5 drives the screw 4 to rotate, and the screw 4 carries the socket block 6 to move up under the action of the thread transmission force, and the socket block 6 moves up along the inner wall of the socket frame 3, and at the same time, the socket block 6 drives the socket rectangular plate 7 to move up, and the socket rectangular plate 7 drives the two blocking airbags 8 to move up. The two blocking airbags 8 move up along the outer wall of the environmental protection gas cabinet 2. At the same time, the controller 20 starts the circulation fan 10, and the circulation fan 10 can generate suction force for the connecting pipe 9, and the connecting pipe 9 sucks the air in the gap surrounded by the socket rectangular plate 7 and the two blocking airbags 8. The air is pressurized by the circulation fan 10 and quickly enters the first helium detector 11, and is detected by the first helium detector 11, and then transported to the rear position of the socket rectangular plate 7 through the circulation pipe 12, and continues to enter the gap surrounded by the socket rectangular plate 7 and the two blocking airbags 8. In this way, when the sleeve rectangular plate 7 moves upward, the helium leakage position outside the environmental protection gas cabinet 2 is quickly detected. When the first helium detector 11 detects helium, it is known that a helium leakage position appears in the gap surrounded by the sleeve rectangular plate 7 and the two blocking airbags 8.
[0046] The controller 20 immediately turns off the driving motor 5. At this time, the two blocking airbags 8 and the sleeve rectangular plate 7 can be located at the helium leakage position outside the environmental protection gas cabinet 2. The controller 20 immediately opens the air inlet valve 14. The air pump 13 is started. The air pump 13 enables the air inlet valve 14 to pressurize the external air into the inside of the boosting pipe 15, and then enters the inside of the two blocking airbags 8 through the boosting pipe 15. After the two blocking airbags 8 are pressurized and expanded, the two blocking airbags 8 are squeezed and sealed at the outer wall of the environmental protection gas cabinet 2. In this way, the two blocking airbags 8 and the sleeve rectangular plate 7 can automatically and timely completely seal the helium leakage position. Then the controller 20 closes the air inlet valve 14 and the boosting pipe 15 to prevent helium from continuously leaking. The distance sensor 26 performs distance sensing on the sleeve block 6, and the distance value sensed by the distance sensor 26 is displayed on the controller 20.
[0047] Step 3: When the top is detected and blocked, the controller 20 starts the transmission motor 29, and the transmission motor 29 drives the transmission screw 28 to rotate. The transmission screw 28 rotates inside the support frame 27, and the sleeve frame 3 supports the support frame 27 to increase the stability of the support frame 27. The transmission screw 28 carries the threaded sleeve block 30 and moves leftward under the action of the thread transmission force. The threaded sleeve block 30 moves leftward along the inner wall of the support frame 27, and the threaded sleeve block 30 drives the sleeve sealing plate 31 to move leftward. The sleeve sealing plate 31 drives the rectangular airbag 32 to move leftward, and the rectangular airbag 32 is attached to the upper surface of the multiple environmental protection gas cabinets 2 and moves leftward. At the same time, the controller 20 starts the detection fan 34, and the detection fan 34 generates suction in the suction pipe 33. The suction pipe 33 can inhale the air in the space surrounded by the rectangular air bag 32 and the sleeve sealing plate 31. The air enters the detection fan 34 along the suction pipe 33, and the air enters the second helium detector 35 for detection along the detection fan 34. The air enters the guide pipe 36 through the second helium detector 35, and continues to circulate from the guide pipe 36 to the space surrounded by the rectangular air bag 32 and the sleeve sealing plate 31.
[0048] When the second helium detector 35 detects helium, the transmission motor 29 is turned off through the controller 20, and the rectangular airbag 32 and the sleeve sealing plate 31 stop at this time, and the rectangular airbag 32 and the sleeve sealing plate 31 can be located at the helium leakage position on the top of the environmental protection gas cabinet 2. At the same time, the controller 20 starts the booster air pump 38, opens the suction valve 39, and the external booster air enters the delivery pipe 37, and enters the rectangular airbag 32 through the delivery pipe 37. The rectangular airbag 32 can be expanded and squeezed at the top position of multiple environmental protection gas cabinets 2, so that the sleeve sealing plate 31 and the rectangular airbag 32 can completely seal the top position of the environmental protection gas cabinet 2, and then the controller 20 closes the suction valve 39 and the booster air pump 38 to prevent the helium from continuing to leak from the top of the environmental protection gas cabinet 2.
[0049] Step 4, when replenishing helium, the controller 20 starts to open the top valve 43 and the controller 20 opens the outer valve 45. The controller 20 starts the booster pump 41 at the same time. The booster pump 41 pressurizes the helium inside the helium storage bottle 40 and enters the delivery hose 42. The pressurized helium enters the top valve 43 along the delivery hose 42. Since the top valve 43 and the sleeve sealing plate 31 are in a fixed connection state, the pressurized helium can enter the gap surrounded by the sleeve sealing plate 31 and the rectangular airbag 32, and the helium leakage part on the top of the environmental protection gas cabinet 2 is replenished with helium. The helium can be replenished into the gap surrounded by the environmental protection gas cabinet 2 and the inflation sleeve 17 to continue the sealing protection. At the same time, the supplementary helium inside the delivery hose 42 can also enter the inside of the connecting hose 44, enter the peripheral valve 45 through the connecting hose 44, and enter the gap surrounded by the sleeve rectangular plate 7 and the two blocking airbags 8 through the peripheral valve 45. The helium can be used to supplement the helium leakage part outside the environmental protection gas cabinet 2. After the supplement, when the pressure value of the pressure transmitter 19 is the pressure value set by the controller 20, the controller 20 immediately closes the top valve 43 and the peripheral valve 45 to complete the automatic supplement of helium, ensuring that the inside of the environmental protection gas cabinet 2 can be safely closed and used. When the above leakage parts are shut down for maintenance, they can be quickly repaired by professionals.
