Description

Technical Field

[0001] The present invention relates to the technical field of voltage transformers, and in particular to an anti-resonance voltage transformer. Background Art

[0002] A voltage transformer is an instrument used to transform voltage. However, the purpose of a transformer transforming voltage is to facilitate the transmission of electrical energy, so its capacity is very large and is generally calculated in kilovolt-amperes or megavolt-amperes. The purpose of a voltage transformer transforming voltage is mainly to power measuring instruments and relay protection devices, to measure the voltage, power and electrical energy of the line, or to protect valuable equipment, motors and transformers in the line when a line fault occurs. Therefore, in the construction of ring network cabinets, in order to improve and perfect the anti-resonance function, most of them will be installed with this type of voltage transformer.

[0003] When existing voltage transformers are installed inside a ring main unit (RMU), they are often fastened together with a mounting flange at the bottom of the voltage transformer and a fixed sheet metal inside the RMU via multiple fastening bolts. Due to the relatively small space, installers need to use various complex postures when installing the bolts distributed in a rectangular array, making installation very difficult. The same difficulty will still occur during subsequent disassembly. At the same time, the tight installation environment around the RMU can easily cause the transformer to become overheated, preventing heat from being dissipated effectively. Summary of the Invention

The present invention has a novel structure. Through the cooperation of the mounting plate and the limit frame, the transformer can be conveniently sent into the ring network cabinet and fixedly installed. Through the cooperation of the drive component and the heat dissipation component, the stability of the transformer installation is enhanced. At the same time, the surroundings of the transformer are connected to form a passage, which can efficiently ventilate and dissipate heat around the transformer, avoid heat accumulation, facilitate installation and disassembly, and maintain the temperature around the transformer not too high.

[0006] Furthermore, a slide groove is provided on the surface of the mounting plate at the bottom of the limit frame, and the bottom of the limit frame slides along the slide groove, and a fixing bolt is inserted between the limit frame and the rear end of the base of the transformer body.

[0007] Furthermore, the drive assembly also includes a sliding frame, and two sliding frames are fixed on the front and rear ends of the mounting plate. A screw is rotatably installed inside the sliding frame through a bearing, a slider is threadedly sleeved on the surface of the screw, and a fixed plate is fixed on the top of the slider.

[0008] Furthermore, the heat dissipation assembly also includes a receiving groove, the front end of the mounting plate is provided with a receiving groove, and the bottom of the vertical plate is rotatably mounted inside the receiving groove via a rotating shaft.

[0009] Furthermore, a first gear is installed on the outer wall of the storage slot corresponding to the rotation connection of the two vertical plates, a second gear is meshed and connected between the two first gears, and the second gear is rotatably installed on the outside of the mounting plate through a bearing.

[0010] Furthermore, a rotating rod is fixed between the two screw rods, a first bevel gear is fixed at the center of the first gear, a second bevel gear is fixed on the surface of the rotating rod, and the first bevel gear is meshed with the second bevel gear.

[0011] Furthermore, two first connecting tubes are fixed on both sides of the side panel, and a bellows is fixed on the outer end of the first connecting tube. Second connecting tubes are arranged at positions corresponding to the bellows on both sides of the vertical plate and the limit frame. The movable end of the bellows is fixed through the fixed plate, and the second connecting tube is plugged into and installed with the bellows.

[0012] Furthermore, an inserting block is fixed on the top of the vertical plate, and the limiting frame is located on the top of the inserting block and is provided with a slot, and the inserting block is slidably inserted into the slot.

[0013] Furthermore, the surfaces of the plug-in block and the slot are respectively provided with rubber ports connected to the cavities of the vertical plate and the limit frame, and the cavities of the vertical plate and the limit frame are connected to the slot through the plug-in block, and air holes are provided on the inner surfaces of the limit frame and the vertical plate.

[0014] Furthermore, two fixed sheet metals are fixed to the rear end of the mounting plate, and the length of the sheet metal exceeds the sliding frame at the rear end of the mounting plate.

[0015] Beneficial effects of the present invention:

[0016] 1. The rear end of the mounting plate of the present invention is pre-fixed inside the ring network cabinet by a sheet metal part, serving as a base for supporting the transformer body. The mounting plate does not need to be removed when repairing the transformer body. At the same time, the length of the sheet metal part can also avoid the movement of the structure inside the sliding frame at the rear end of the mounting plate being restricted, affecting the connection between the side plate and the limit frame through the pipeline.

[0017] 2. The present invention also adopts the form of a rubber socket between the movable end of the bellows and the second connecting pipe, that is, the bellows and the second connecting pipe have a larger diameter than the other, and the larger diameter is elastic. Through the push of the fixed plate, the bellows and the second connecting pipe are squeezed and the larger diameter is sleeved on the outside of the smaller diameter to form a pipeline connection. This structure is convenient for disassembly. Before sending out the transformer body, the vertical plate is stored back into the receiving groove. At the same time, the bellows is separated from the second connecting pipe and folded and moved toward one end of the first connecting pipe to avoid interfering with the sending out of the transformer body.

[0018] 3. The present invention meshes the first bevel gear with the second bevel gear, and the first gear and the second gear mesh and rotate synchronously. Because the first gear is respectively connected to the rotating shafts of the two vertical plates, and the two second gears are in the middle as transmission gears, the rotation directions of the two vertical plates are opposite. At the same time, they rotate to a vertical shape from the inside of the storage slot, and the plug-in block is inserted into the slot to connect the vertical plate with the cavity at the front end of the limit frame. At the same time, the plug-in block is connected to the slot to limit the limit frame and the base, thereby enhancing the stability of the transformer body after installation.

[0019] 4. The present invention drives the screw to rotate by a rotating rod, and the slider cooperates with the screw thread to slide along the slide frame, and the fixed plate drives the bellows to expand, and connects the side plate and the vertical plate cavity as well as the side plate and the limit frame cavity respectively to form a complete passage. The air inlet at the bottom of the mounting plate is connected to a heat dissipation device, such as a fan or a ventilation duct, etc., which can simultaneously dissipate heat and blow air around the transformer body, with higher heat dissipation efficiency, avoiding heat accumulation. When the transformer body needs to be delivered, the rotating rod is rotated in the opposite direction, the vertical plate is stored and recovered in the storage slot, and the front end of the mounting plate is opened to facilitate manual pulling out of the transformer body.

[0020] 5. The present invention pulls the limit frame outward along the slide groove, sleeves it on the bottom of the transformer body, and locks it with the base of the transformer body through the fixing bolts at the bottom. It is fixedly installed on the return mounting plate from the outside, which can avoid the problem that the internal space of the ring network cabinet is small and inconvenient for installation. At the same time, the locking installation of a fixing bolt and the structure on the mounting plate can achieve a stable and convenient locking installation effect, thereby reducing the time spent on installation.

[0021] 6. Compared with the prior art, the present invention facilitates the insertion and fixed installation of the transformer into the ring network cabinet through the cooperation of the mounting plate and the limit frame. The stability of the transformer installation is enhanced through the cooperation of the driving component and the heat dissipation component. At the same time, the surroundings of the transformer are connected to form a passage, which can effectively ventilate and dissipate heat around the transformer, avoid heat accumulation, facilitate installation and disassembly, and maintain the temperature around the transformer not too high.

Because the first gear 31 is respectively connected to the rotating shafts of the two vertical plates 45, and the two second gears 32 are in the middle as transmission gears, the rotation directions of the two vertical plates 45 are opposite. At the same time, they are rotated to a vertical shape from the inside of the storage groove 46, and the plug block 18 is inserted into the inside of the slot 17 to connect the vertical plate 45 with the cavity at the front end of the limit frame 14. At the same time, the plug block 18 is connected to the slot 17, which can limit the limit frame 14 and the base 21, thereby enhancing the stability of the transformer body 2 after installation.

When the vertical plate 45 rotates, the rotating rod 3 5 drives the screw 39 to rotate, and the slider 37 and the screw 39 threadedly cooperate to slide along the slide frame 36. The fixed plate 38 drives the bellows 44 to expand, and the side plate 41 and the vertical plate 45 cavity and the side plate 41 and the limit frame 14 cavity are connected respectively to form a complete passage. The air inlet at the bottom of the mounting plate 1 is connected to a heat dissipation device, such as a fan or a cold air duct, etc., which can simultaneously dissipate heat and blow air around the transformer body 2, with higher heat dissipation efficiency to avoid heat accumulation. When the transformer body 2 needs to be delivered, the rotating rod 35 is rotated in the opposite direction, the vertical plate 45 is stored and recovered in the receiving groove 46, and the front end of the mounting plate 1 is opened for easy human intervention. Pull out the transformer body 2, and a rubber socket is also used between the movable end of the bellows 44 and the second connecting tube 47, that is, the bellows 44 and the second connecting tube 47 have a larger diameter than the other, and the larger diameter is elastic. Through the push of the fixed plate 38, the bellows 44 and the second connecting tube 47 are squeezed and the larger diameter is sleeved on the outside of the smaller diameter to form a pipeline connection. This structure is convenient for disassembly. Before sending out the transformer body 2, the vertical plate 45 is stored and recovered in the receiving groove 46. At the same time, the bellows 44 is separated from the second connecting tube 47 and folded and moved toward one end of the first connecting tube 43 to avoid interfering with the sending out of the transformer body 2.
