Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformer parts, and particularly relates to a phase spacing plate structure for a 35KV power transformer. BACKGROUND

[0002] During the operation of the 35KV power transformer, the phase spacing plate as a core insulation component is mainly used for isolating the windings of different phases in the transformer, preventing inter-phase breakdown discharge, and ensuring the insulation performance and operation stability of the transformer.

[0003] The document with the prior art publication number CN105742037B provides a three-dimensional volume iron core transformer phase spacing plate and a manufacturing method thereof, which reduces the insulation distance between transformer phases, reduces the electrical distance from the coil end to the upper and lower yokes, and improves the breakdown voltage of the oil gap; the application of the present application constitutes the real small oil gap principle of oil-separator-oil-separator-oil, applies the volume effect of transformer oil, improves the electric strength of the transformer oil, forms an additional electric field in the uniform electric field and the non-uniform electric field, changes the distribution of the original electric field, makes it uniform, and the uniformity of the electric field increases with the increase of the number of separators, and improves the breakdown voltage of the transformer oil gap.

[0004] The prior art supports and connects the two side spacing plates through the horizontally placed support bars. Since the support bars are horizontally placed, the air circulation between the two side spacing plates is limited, resulting in poor heat dissipation effect between the spacing plates. Poor heat dissipation leads to high temperature, which affects the working stability and service life of the transformer. The horizontal support bar connection causes the overall rigidity of the spacing plate to be low, and deformation or aging is easily caused during long-term use, thereby affecting the insulation performance and electric field distribution of the spacing plate, reducing the breakdown voltage, and affecting the safety of the transformer.

[0005] In summary, in the prior art, there is a lack of technology for stable support and heat dissipation between the phase spacing plates. SUMMARY

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The phase partition structure shown includes a partition 1, a spiral connecting frame 2 fixedly connected to the middle of the partition 1, an anti-blocking mechanism 3 fixedly connected to the middle of the partition 1, guide rail plates 4 fixedly connected to both sides of the partition 1, a movable frame 5 above the guide rail plate 4, a movable seat 6 fixedly connected to the bottom of the movable frame 5, a cleaning belt 7 rotatably connected to the movable frame 5, a treatment seat 8 slidably fitted to the outer wall of the cleaning belt 7, a transmission mechanism 9 rotatably connected through the treatment seat 8, and a dust removal mechanism 10 on one side of the transmission mechanism 9.

[0031] like Figure 3 As shown, a reinforcing rib 101 is fixedly connected at the bend of the partition 1.

[0032] like Figure 3 As shown, the spiral connecting frame 2 has a guide groove 201 inside, and pipe joints 202 are fixedly connected to both ends of the spiral connecting frame 2.

[0033] By setting a spiral connecting frame 2 between the partitions 1, the connection strength between the partitions 1 can be improved through the spiral structure. The spiral shape makes the mechanical connection between the partitions 1 tighter and more stable, avoiding the deformation or loosening that may be caused by traditional support structures, thereby improving the stability of the partitions 1 under high voltage environment. The spiral structure design can help to evenly distribute the electric field in the transformer, avoiding the risk of local breakdown caused by excessive electric field strength. At the same time, by setting a flow guide groove 201 in the spiral connecting frame 2, together with the pipe joints 202 at both ends, good oil or air flow can be achieved, thereby improving heat dissipation efficiency. The design of the flow guide groove 201 allows oil or air to pass through, so that the temperature around the partition 1 can be effectively regulated, avoiding overheating.

[0034] like Figure 4 As shown, the anti-blocking mechanism 3 includes a fixed plate 301, which is fixedly connected to the partition 1. A toggle bracket 302 is provided on one side of the fixed plate 301. The inner wall of the hole in the toggle bracket 302 is slidably fitted with the outer wall of the pipe connector 202. A rubber pad is provided on the inner wall of the toggle bracket 302. Two connecting rods 303 are symmetrically connected and rotatably mounted on one side of the toggle bracket 302. A sliding bracket 304 is rotatably connected to the other end of the connecting rods 303. The sliding bracket 304 is slidably fitted with the fixed plate 301. A cover 305 is fixedly connected to one end of the sliding bracket 304, and one side of each cover 305 is in slidable contact with the port of the pipe connector 202. The anti-blocking mechanism 3 seals the port of the pipe connector 202 during the transfer and installation of the partition 1, preventing debris from falling in and causing blockage. The rubber pad increases the friction of the toggle bracket 302, enabling it to be fixed in place.

[0035] like Figure 5 As shown, a slider 601 is fixedly connected to the bottom of the movable seat 6, and the slider 601 is slidably engaged with the inner wall of the guide rail plate 4. A pin is rotatably connected through the movable seat 6, a worm gear 602 is fixedly connected to the top of the pin, and a drive wheel 603 is fixedly connected to the bottom of the pin. A rack 401 is fixedly connected to the inner wall of the guide rail plate 4, and the rack 401 meshes with the drive wheel 603 for transmission. Multiple rollers 604 are rotatably connected to the middle of the slider 601, and the rollers 604 are slidably in contact with the inner wall of the guide rail plate 4. The rollers 604 make the movement of the movable seat 6 more stable and effortless.

[0036] like Figure 6As shown, both ends of the cleaning belt 7 are equipped with friction-driven pulleys 701, which are rotatably connected to the movable frame 5. Multiple guide shafts 702 are frictionally contacted on the cleaning belt 7, and are rotatably connected to the movable frame 5. A insertion hole 703 is opened at the center of one end of the lower pulley 701. A transmission rod 704 is movably inserted into the inner wall of the insertion hole 703. An electric actuator is fixedly connected to one end of the transmission rod 704, and a worm gear 705 is fixedly connected to the other end. A motor 706 is fixedly connected to one end of the worm gear 705, which is fixedly connected to the movable seat 6. The worm gear 705 meshes with the worm wheel 602 for transmission. A sponge pad is fixedly connected to one side of the cleaning belt 7. The electric actuator can drive the transmission rod 704 intermittently.

[0037] like Figure 7 As shown, a collection filter tube 801 is threadedly connected to the bottom opening of the treatment seat 8, and the treatment seat 8 is fixedly connected to the movable frame 5.

[0038] like Figure 7 As shown, the transmission mechanism 9 includes a fan blade 901, which is located inside the bottom opening of the processing base 8. The shaft end of the fan blade 901 is rotatably connected to the inner wall of the processing base 8. A universal joint is fixedly connected to the outside of the shaft end of the fan blade 901, and the other end of the universal joint is fixedly connected to the pulley 701 located on the upper side. A drive wheel 902 is fixedly connected to the shaft end of the fan blade 901. The fan blade 901 can collect clean dust to avoid secondary pollution.

[0039] like Figure 8 As shown, the dust removal mechanism 10 includes a scraper 1001. One side of the scraper 1001 is in slidable contact with the sponge pad on one side of the cleaning belt 7. One end of the scraper 1001 is rotatably connected to the inner wall of the treatment seat 8. A transmission wheel A1002 is fixedly connected to one end of the scraper 1001. A universal joint is fixedly connected to one side of the transmission wheel A1002. The universal joint is rotatably connected to the inner wall of the treatment seat 8. A driven wheel 1003 is fixedly connected to the other end of the universal joint. The driven wheel 1003 meshes with the driving wheel 902 for transmission. A transmission wheel B1004 is meshed with one side of the transmission wheel A1002 for transmission. A vibration rod 1005 is fixedly connected to the transmission wheel B1004. The vibration rod 1005 is rotatably connected to the inner wall of the treatment seat 8. Multiple rods of different lengths are fixedly connected to the vibration rod 1005. The vibration rod 1005 is in movable contact with one side of the cleaning belt 7. The blades on the scraper 1001 are designed with an arc shape, which is beneficial for scraping off dirt attached to the sponge pad.

[0040] Working principle: After the partition 1 is installed, by pushing the actuating frame 302, the actuating frame 302 can drive the two sliding frames 304 to move through the connecting rod 303, so that the sliding frame 304 drives the connected cover 305 to move away from the pipe joint 202 port, making it convenient for the pipe joint 202 to be connected to the pipe.

[0041] During the use of partition 1, when it is necessary to clean partition 1, the motor 706 drives the connected worm gear 705 to rotate, so that the worm gear 705 drives the transmission rod 704 connected to the electric push rod to rotate, so that the transmission rod 704 can drive the pulley 701 to rotate. At this time, the pulley 701 will drive the cleaning belt 7 to rotate, so that the sponge pad on the cleaning belt 7 cleans the partition 1.

[0042] At the same time, the worm gear 705 will drive the worm wheel 602 on one side to rotate, which will cause the worm wheel 602 to drive the connected drive wheel 603 to rotate. At this time, under the action of the rack 401, the drive wheel 603 will drive the moving seat 6 to move on the guide plate 4, thereby driving the cleaning belt 7 to move laterally for cleaning.

[0043] When the cleaning belt 7 rotates counterclockwise for cleaning, it will drive the fan blade 901 connected to the universal joint to rotate through another pulley 701, which will drive the drive wheel 902 connected to rotate. At this time, the drive wheel 902 will drive the driven wheel 1003 to rotate, which will drive the scraper wheel 1001 connected to the universal joint to rotate, and scrape and clean the surface of the sponge pad on the cleaning belt 7 that has entered the treatment seat 8.

[0044] Simultaneously, the scraper wheel 1001 drives the transmission wheel B1004 to rotate rapidly via the transmission wheel A1002, causing the vibrating rod 1005 connected to the transmission wheel B1004 to rotate. At this time, the rods of different lengths on the vibrating rod 1005 will strike the cleaning belt 7, and the vibration will cause the dust inside the sponge pad to overflow. Under the action of the fan blade 901, the dust can be filtered through the collection filter tube 801 to avoid secondary contamination of the sponge pad. After the cleaning belt 7 has finished cleaning the partition 1, the electric push rod drives the transmission rod 704 to move out of the insertion hole 703, so that when the motor 706 reverses and drives the moving seat 6 to reset, the cleaning belt 7 will not rotate.
