Description

An outdoor fully enclosed insulated ring network switch cabinet

Technical Field

The invention relates to the technical field of electric power equipment, and in particular to an outdoor fully enclosed insulating ring network switch cabinet.

Background Art

Insulated ring network switchgear is an electrical equipment in which a group of high-voltage switchgear is installed in a steel plate metal cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

In the prior art, a Chinese patent document with publication number CN110635374B proposes a new type of insulated enclosed gas-filled ring network switchgear, in which the switch cabinet is arranged in a housing, and further includes a controller, a temperature sensor, an adjustment mechanism and a circulating cooling pipe. The controller is arranged in the housing, the temperature sensor is arranged in the switch cabinet, the temperature sensor signal is connected to the controller, the adjustment mechanism is arranged on the inner wall of the housing, and the circulating cooling pipe is fixed on the adjustment mechanism. Although this technology uses groundwater to cool the switch cabinet and consumes less energy, this technology is consistent with the traditional method in that the switch cabinet in the traditional technology is usually closed with an ordinary opening and closing door panel when in use, and the connection of such door panels has obvious Gaps. This type of door panel is also connected by hinges. The screws of the hinge connection become loose due to long-term use, which is prone to misalignment. After long-term use, the gap is more likely to expand further, making it impossible to completely isolate dust and moisture. Especially in harsh environments (such as sandstorms or rainy seasons), internal equipment is easily damaged, resulting in frequent failures. At the same time, traditional switch cabinets are usually placed directly on the ground when installed outdoors, and are easily affected by ground moisture and water accumulation, especially on rainy days. Ground water will seep into the cabinet and damage internal equipment. At the same time, ground moisture and water accumulation will cause moisture inside the equipment and reduce electrical insulation performance, thereby increasing equipment failure rate and maintenance costs.

A retracting mechanism is installed inside the rain cover 32. The retracting mechanism is used to facilitate the retraction of the two extension covers 33.

By setting up the closing assembly and the back plate 50, it is ensured that the inside of the switch cabinet is completely isolated from the outside world, effectively preventing the entry of dust and moisture, extending the service life of the equipment, and ensuring the stable operation of the equipment in harsh environments. At the same time, a U-shaped protective shell 3 is adopted. When repairing the switch cabinet, it is only necessary to raise the protective shell 3, and the cabinet body can be repaired from the three sides of the inner frame 1, thereby avoiding the traditional trouble of manual disassembly and repair of the cabinet body.

As shown in Figures 1 to 6, the outer shape of the inner frame 1 is a cube composed of four U-shaped frames and a top plate. A slide groove 4 is provided inside the top of the fixing frame 2. One side of the bottom of the fixing frame 2 is fixedly connected to the outside of the four corners of the inner frame 1.

By setting the inner frame 1 as a cube consisting of four U-shaped frames and a top plate and a back plate 50, the middle part of the U-shaped frame is hollowed out, and two adjacent frames of the four U-shaped frames are vertically connected, which facilitates the installation of internal source components of the switch cabinet. The top plate is installed on the top of the four U-shaped frames and its size is adapted to the space formed by the four U-shaped frames. Its main function is to facilitate the installation of the second cooling fan 27 and the rain cover 32 in the later stage. At the same time, the protective shell 3 can be used to completely enclose the switch cabinet in a space in the later stage, thereby avoiding the entry of rainwater and external dust. At the same time, the fixed frame 2, the slide groove 4 and the protective shell 3 are composed of three T-shaped plates, which can stabilize the protective shell 3 while enabling the tops of the three surfaces of the protective shell 3 to be connected to each other, thereby facilitating the sliding of the protective shell 3 in the slide groove 4, which is beneficial to the later maintenance. At the same time, the vertical plug 7 and the horizontal plug are made of rubber material, which can increase the sealing between the protective shell 3 and the inner frame 1, thereby avoiding the erosion of rainwater.

As shown in FIGS. 1 to 6 , a partition 25 is fixedly connected to the interior of the inner frame 1, a first heat dissipation fan 26 is installed inside the bottom of the partition 25, a second heat dissipation fan 27 is installed on the top of the inner frame 1, and a plurality of heat dissipation holes 51 are also opened on the top of the inner frame 1, and the plurality of heat dissipation holes 51 are located between the partition 25 and the side wall of the inner frame 1, and the fixed cylinder 21 is located between the partition 25 and the side wall of the inner frame 1;

By setting up the second cooling fan 27, the top of the switch cabinet can be cooled, thereby avoiding the problem of rainwater entering the cabinet through the heat dissipation point. At the same time, by setting up the partition 25, the first cooling fan 26 and the heat dissipation hole 51, the first cooling fan 26 can absorb the heat at the bottom of the cabinet and input it between the partition 25 and the side wall of the inner frame 1. At this time, the principle of hot air rising is used to cause the heat to dissipate from the heat dissipation hole 51, thereby facilitating the heat dissipation of the switch cabinet and avoiding the problem of rainwater entering the cabinet through the heat dissipation hole 51.

As shown in Figures 1 to 8, one end of the first support rod 9 and the second support rod 10 are respectively fixedly connected with a sector tooth 11, the sector teeth 11 at one end of the two first support rods 9 inside the support frame 8 are meshed with each other, and the sector teeth 11 at one end of the two second support rods 10 inside the connecting block 12 are meshed with each other, and the connection at one end of the first support rod 9 and the second support rod 10 is connected to a positioning block 14 through an axial rotation, and the connection at the other end of the first support rod 9 and the second support rod 10 is connected to a screw block 13 through an axial rotation, and the end of the screw rod 20 away from the driven wheel 15 is connected to the internal thread of the screw block 13, and the end of the screw rod 20 away from the screw block 13 is connected to the internal rotation of the positioning block 14 and is connected to the driven wheel One side of the driven wheel 15 is fixedly connected, one end of the connecting line 53 away from the rear plate 50 is electrically connected to the external line source, the length of the connecting line 53 between the rear plate 50 and the external line source is adapted to the height of the switch cabinet lifted by the fixed plate 5, one side of the driven wheel 15 is connected to the second umbrella-shaped tooth 19 through the shaft rotation, one side of the second umbrella-shaped tooth 19 is meshed and connected to the first umbrella-shaped tooth 18, the top of the first umbrella-shaped tooth 18 passes through the bottom of the fixed plate 5 through the shaft and is fixedly connected to the bottom of the third gear 46, the specification size of the third gear 46 is larger than the specification size of the fourth gear 47, and when the fixed plate 5 is raised to the highest point, the bottom of the protective shell 3 just moves to the lowest point of the inner frame 1;

By setting the lifting assembly, the switch cabinet can be kept away from moisture and water on the ground in the outdoor environment, especially on rainy days, it can prevent water from entering the cabinet, thereby protecting the safety of the internal equipment. At the same time, it can also prevent animals on the ground from entering the cabinet, which may cause short circuits and damage to the cabinet, thereby reducing the equipment failure rate and maintenance costs. When it is raised for use, the rotating wheel 17 is rotated to drive the driving wheel 16 to drive the screw rod 20 inside the support frame 8 to rotate, and the driving wheel 16 drives the driven wheel 15 to rotate. At this time, the driven wheel 15 drives the screw rod 20 inside the other support frame 8 to rotate. At this time, through the action of the thread, the screw block 13 will move to one side of the positioning block 14, while driving the first support rod 9 and the first support rod 9. The connecting ends of the two support rods 10 move toward one side of the positioning block 14, at this time, the other ends of the first support rod 9 and the second support rod 10 will move away from each other, and at the same time, through the action of the fan-shaped teeth 11, the other ends of the first support rod 9 and the second support rod 10 that are away from each other will move away again, thereby prompting the two second support rods 10 to lift the connecting block 12, and at the same time prompting the fixing plate 5 to raise the switch cabinet, thereby avoiding the problem of ground water entering the cabinet when it rains later. At the same time, through the provided linkage component, the automatic linkage of the closing component and the lifting component is realized, the switch cabinet is automatically closed when it is raised, and the switch cabinet is automatically opened when it is lowered, which simplifies the operation process and improves the convenience and efficiency of maintenance and installation. At the same time, during later maintenance, the reverse rotation The driven wheel 15 drives the second umbrella-shaped tooth 19 to rotate, and the first umbrella-shaped tooth 18 drives the third gear 46 to rotate. At this time, the fourth gear 47 will drive the threaded rod 22 to rotate, thereby prompting the movable block 23 to move upward with the protective shell 3 using the connecting plate 24, thereby prompting the protective shell 3 to rise when the fixed plate 5 descends, thereby facilitating later maintenance, thereby avoiding the trouble of operating the two mechanisms separately, thereby improving maintenance and installation efficiency. At the same time, by setting the specification size of the third gear 46 to be larger than the specification size of the fourth gear 47, when the third gear 46 rotates, the fourth gear 47 is prompted to rotate with the threaded rod 22 faster than the third gear 46, thereby achieving a fixed position. When the fixed plate 5 drops to the lowest point, the protective shell 3 just rises to the highest point, thereby improving the linkage and avoiding the problem that the protective shell 3 is still blocking one side of the inner frame 1 when the fixed plate 5 is raised. Such a design is conducive to the maintenance of the switch cabinet. It should be noted that when using a large switch cabinet in the later stage, in order to save manpower, a motor can be connected to the driving wheel 16 to drive the driving wheel 16 to rotate, thereby saving manpower and improving work efficiency. At the same time, by setting the length of the connecting line 53 between the rear plate 50 and the external line source to match the height of the switch cabinet raised by the fixed plate 5, the connecting line 53 can be lifted and lowered when the switch cabinet is lifted and lowered, thereby not affecting the normal use of the power supply of the switch cabinet.

As shown in Figures 2 to 12, two second connecting blocks 55 are fixedly connected to the two ends of the rain cover 32, and the folding plate 45 is fixedly connected to the first connecting block 54 at one end opposite to the rain cover 32. The first connecting block 54 is fixedly connected to the inside of the shaft 56, and the two ends of the shaft 56 are respectively rotatably engaged with the inside of the second connecting block 55. The bottoms of the two ends of the rain cover 32 are fixedly connected with stop blocks 57, and the stop blocks 57 have a V-shaped shape. The end of the stop block 57 away from the rain cover 32 contacts the bottom of one end of the folding plate 45, and the length of the stop block 57 is equal to the width of the rain cover 32. The rain cover 32 has a V-shaped shape, and the folding plate 45 is located at the top of the protective shell 3. The top of the inner frame 1 is fixedly connected with a baffle 49, and the baffle 49 has a U-shaped shape. The two extension covers 33 are respectively located inside the two sides of the rain cover 32, and the width of the two extension covers 33 when one side is in contact is equal to the width of the rain cover 32.

By means of the provided covering assembly, the top of the inner frame 1 can be covered, which effectively prevents rainwater from corroding the switch cabinet and protects the safety of the internal equipment. At the same time, by means of the provided support rod 52, the rain cover 32 can be raised, thereby facilitating the heat dissipation in the cabinet by the second cooling fan 27. At the same time, by means of the provided folding plate 45, the rain shielding area can be increased. When the protective shell 3 moves upward, the top of the protective shell 3 will contact the bottom of the folding plate 45. At this time, the folding plate 45 is rotatably connected to the second connecting block 55 at one end of the rain cover 32 through the shaft 56 inside the first connecting block 54. At this time, the folding plate 45 will rotate upward, thereby preventing the folding plate 45 from blocking the protective shell. The problem of shell 3 moving. At the same time, after the protective shell 3 is lowered, the shape of the stop block 57 is V-shaped. Due to the action of gravity, the folding plate 45 will rotate downward. At this time, one side of the folding plate 45 will contact the top of the stop block 57 away from the end of the rain cover 32 to continue to block the rain. At the same time, the stop block 57 is set in a V shape and the length of the stop block 57 is equal to the width of the rain cover 32. When water flows on the top of the rain cover 32, it will flow along the slope of the rain cover 32 into the joint between the rain cover 32 and the folding plate 45. At this time, it will flow into the inside of the stop block 57, thereby prompting rainwater to flow out from both ends of the stop block 57, thereby avoiding the problem of fine rainwater flowing into the top of the switch cabinet.

As shown in Figures 1 to 12, the retraction mechanism includes two positioning plates 34 fixedly connected to the inner wall of the rain cover 32, the two positioning plates 34 are symmetrically arranged, the positioning plates 34 are slidably connected with a rack 35 inside, the two sides of the two ends of the rack 35 are respectively fixedly connected to a limit block 40, the limit block 40 is internally slidably connected to a limit rod 41, the outer sleeve of the limit rod 41 is provided with a return spring 42, the end of the limit rod 41 away from the limit block 40 is fixedly connected to a moving block 43, one end of the return spring 42 is fixedly connected to one side of the limit rod 41, and the other end of the return spring 42 is fixedly connected to one side of the limit block 40, the tops of the two ends of the positioning plates 34 are respectively fixedly connected to limit posts 38, one side of the rack 35 is fixedly connected to a positioning post 37, the position of the positioning post 37 corresponds to the position of the limiting post 38, the other side of the rack 35 is fixedly connected to a connecting plate 39, and connecting grooves 48 are respectively provided on both sides of the inner wall of the rain cover 32. The end of the plate 39 away from the rack 35 passes through the interior of the connecting groove 48 and is fixedly connected to one side of the extension cover 33. One side of the rack 35 is meshed with an adjusting tooth 36. The top of the middle part of the moving block 43 is fixedly connected with a tooth block 44. The spacing between the tooth block 44 and one end of the rack 35 is equal to the spacing between the external tooth grooves of the adjusting tooth 36. The other side of the adjusting tooth 36 is meshed with the rack 35 on one side of the other positioning plate 34. One side of the adjusting tooth 36 is fixedly connected to the second gear 31 through an axis. The bottom of the second gear 31 is rotatably connected to the top of the inner frame 1 through an axis. One side of the second gear 31 is meshed with the first gear 30. The top of the first gear 30 is fixedly connected to the connecting wheel 29 through an axis. One side of the connecting wheel 29 is connected to the linkage wheel 28 through a belt drive. The bottom of the linkage wheel 28 is fixedly connected to the top of the threaded rod 22 passing through the inner frame 1.

By means of the retracting mechanism, the two extension covers 33 can be extended out of the rain cover 32 during daily rain protection, thereby expanding the covering area of the rain cover 32, which is beneficial to rain protection for the switch cabinet. At the same time, when the protective shell 3 needs to be raised during later maintenance, the two extension covers 33 are retracted to the inside of the rain cover 32 through the retracting mechanism, thereby preventing the extension covers 33 from blocking the rise of the protective shell 3 when the protective shell 3 is raised, which is beneficial to later maintenance. When in use, when the threaded rod 22 rotates to drive the protective shell 3 to rise, the threaded rod 22 will drive the linkage wheel 28 to rotate, and the connecting wheel 29 will drive the first gear 30 to rotate, and at the same time, the second gear 31 will drive the adjusting tooth 36 to rotate. At this time, the racks 35 on both sides of the adjusting tooth 36 will approach each other, thereby prompting the connecting plate 39 to shrink the extension cover 33 to the inside of the rain cover 32, thereby facilitating the rise of the protective shell 3. At the same time, through the return spring 42, the tooth block 44 and the moving block 43, when the extension cover 33 has been shrunk to the inside of the rain cover 32, the adjusting tooth 36 is still rotating. At this time, when the rack 3 When the tooth block 44 moves to the bottom of the adjusting tooth 36, the adjusting tooth 36 will continuously move the tooth block 44 toward one end of the rack 35 through the action of the return spring 42. At this time, through the action of the limiting column 38 and the positioning column 37, the positioning column 37 limits the movement of the rack 35. At the same time, the tooth block 44 also facilitates the rotation of the adjusting tooth 36. At the same time, when the extension cover 33 is extended later, the adjusting tooth 36 rotates in the opposite direction. At this time, the adjusting tooth 36 will move the tooth block 44 away from one end of the rack 35. At this time, through the traction of the return spring 42 , the rack 35 will move to the bottom of the adjusting tooth 36 again, thereby prompting the rack 35 to carry the extension cover 33 away from the interior of the rain cover 32, thereby facilitating the extension cover 33 to shield the top of the inner frame 1 from rain. At the same time, the first gear 30 and the second gear 31 are set, and the large gear drives the small gear to rotate to increase the rotation speed of the adjusting tooth 36, thereby prompting the protective shell 3 to rise. When the top of the protective shell 3 has not yet contacted the bottom of the extension cover 33, the extension cover 33 has been retracted to the interior of the rain cover 32, thereby facilitating the rising of the protective shell 3.
