Description

Technical Field

[0001] The invention relates to the technical field of high-voltage transformer oil, in particular to an ultra-high voltage transformer oil filtering device. Background Art

[0002] Transformer oil, also known as insulating oil or transformer insulating oil, is a kind of oil specially used for insulating and cooling transformers. Transformer oil has high dielectric strength and can effectively isolate the current in electrical equipment to prevent electric shock and arc. Insulating materials immersed in oil can improve dielectric strength and be protected from moisture erosion.

[0003] China Patent Publication No. CN222173342U discloses a transformer oil filter device, which uses a first driven gear to drive a reciprocating filter cartridge to rotate, and a second driven gear to drive a liquid inlet pipe to move back and forth, thereby expanding the contact area between the filter cartridge and the transformer oil and reducing blockage.

[0004] However, the impurities filtered by the device for transformer oil still exist in the filter cartridge. After a long period of accumulation, they will begin to clog the tiny pores on the filter cartridge. This clogging phenomenon will cause the transformer oil to encounter greater resistance when filtering through the filter cartridge, thereby slowing down the flow rate of the oil. Due to the decrease in flow rate, the filtration efficiency of the entire system will also decrease, ultimately affecting the overall filtration quality and efficiency of the transformer oil.

[0031] The scraping mechanism 3 is arranged inside the filter frame 204. The scraping mechanism 3 includes a scraper 306 slidably installed on the inner wall of the filter frame 204. A moving column 305 is fixedly installed on the top surface of the scraper 306. A rotating shaft 302 is arranged above the moving column 305.

[0035] In this embodiment, an elastic member 307 is provided to apply elastic force to the scraper 306 , so that the scraper 306 is in close contact with the inner wall of the filter frame 204 , and the scraper 306 scrapes away impurities on the inner wall of the filter frame 204 more thoroughly.

[0036] Specifically, Figure 1-Figure 8As shown, a hinge rod 308 is fixedly installed on the middle outer wall of the rotating shaft 302, a connecting shaft 314 is fixedly installed on the inner wall of the hinge rod 308, a connecting block 315 is arranged above the connecting shaft 314, an adjusting groove 316 is opened on the side of the connecting block 315, the inner wall of the adjusting groove 316 is slidably connected to the outer wall of the connecting shaft 314, a moving bar 309 is fixedly installed on the top surface of the connecting block 315, the upper end of the moving bar 309 slides through the bottom surface of the cover plate 206 and the inner wall of the concave plate 207 in sequence and extends to the top of the concave plate 207, the two fixed plates 202 are fixedly installed with arc plates 312 on the sides close to each other, the inner wall of the arc plate 312 is fixedly installed with an arc block 313, the inner diameter of the arc block 313 gradually decreases from the middle to the two ends, and the upper end of the moving bar 309 is slidably connected to the inner wall of the arc block 313.

[0037] In this embodiment: by setting the arc block 313, when the moving bar 309 rotates in an arc shape, since the inner diameter of the arc block 313 gradually decreases from the middle to the two ends, the two ends of the arc block 313 push the moving bar 309 and the connecting block 315 to move in a straight line, and the adjustment groove 316 on the connecting block 315 drives the connecting shaft 314 and the hinge rod 308 to rotate a certain angle. Due to the gravity of the scraper 306, the scraper 306 is driven to rotate at an angle opposite to the filter frame 204, pushing impurities into the collection frame 301.

[0038] Specifically, Figure 1-Figure 8 As shown, a fixed block 310 is fixedly installed on the outer wall of the moving bar 309, and an elastic member 311 is slidably sleeved on the outer wall of the moving bar 309.

[0039] In this embodiment, the second elastic member 311 is provided to apply elastic force to the fixed block 310 , thereby applying a continuous upward thrust to the fixed block 310 and the moving bar 309 .

[0040] The specific scheme is as follows: transformer oil is added at a uniform speed from the oil inlet pipe 102, and then enters the filter frame 204 through the hose 218 and the connecting pipe 217, and the motor 213 is turned on to drive the rotating bar 214 and the cylinder 215 to rotate. The cylinder 215 rotates on the inner wall of the groove body 216 and pushes the movable plate 211 to move back and forth. The movable plate 211 drives the connecting rod 209 and the L-shaped bar 208 to rotate back and forth in an arc through the cooperation of the through groove 212 and the ring rod 203. The L-shaped bar 208 drives the concave plate 207, the cover plate 206 and the filter frame 204 to shake back and forth in an arc, so that the filter frame 204 shakes the transformer oil inside and filters it from multiple filter holes, so that the transformer oil can be filtered quickly and the filtering efficiency is improved. When the filter frame 204 and the concave plate 207 rotate back and forth in an arc, the movable bar 309 is driven to rotate back and forth in an arc, and the upper end of the movable bar 309 rotates back and forth in an arc on the inner wall of the arc block 313 The movable bar 309 reciprocates up and down under the joint action of the arc block 313 and the elastic member 2 311, and the lower end of the movable bar 309 pushes the connecting block 315, the hinge rod 308 and the rotating shaft 302 to reciprocate, driving the fixed rod 303, the connecting plate 304, the movable column 305 and the scraper 306 to reciprocate in an arc. At the same time, under the action of the elastic member 1 307, the scraper 306 is in close contact with the inner wall of the filter frame 204, and the scraper 306 and the filter frame 204 reciprocate in the opposite direction of the arc, so that the scraper 306 scrapes the impurities on the inner wall of the filter frame 204 into the collecting frame 301, ensuring that the gap on the filter frame 204 will not be blocked by impurities, so that the speed of the oil flowing through the filter frame 204 will not be slowed down and the impurities will not further contaminate the oil, thereby improving the overall filtering quality and efficiency of the transformer oil, and then collecting the filtered oil from the oil outlet pipe 103.
