Description

Technical Field

[0001] The utility model relates to the technical field of unloaded strip switches, in particular to a novel unloaded strip switch fixing structure. Background Art

[0002] The off-excitation strip tap changer is a type of switch. The off-excitation strip tap changer is suitable for oil-immersed power transformers with a frequency of 50 Hz, a rated voltage level between 10,000 volts and 30,000 volts, and a rated through-current between 10 amperes and 63 amperes. Voltage is an important quality indicator in the power system. When the power system is operating normally, voltage changes will cause abnormal operation of electrical equipment, directly affecting production and daily life. Therefore, voltage regulation is one of the main tasks of the power system.

[0003] The existing new type of unloaded strip switch fixing structure needs to be bolted to the transformer oil tank to ensure safe operation. The fixing point needs to be operated with a hand hole flange on the oil tank body, which increases the oil leakage point of the oil-immersed transformer and part of the processing cost. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a novel unloaded bar switch fixing structure to solve the technical problem of the complexity of the unloaded bar switch installation process.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel unloaded bar switch fixing structure, comprising a fuel tank cover, a first guide groove is fixedly connected to one side of the bottom of the fuel tank cover, a through hole is provided on the fuel tank cover, a switch is arranged inside the through hole, an unloaded bar switch is arranged at the bottom of the switch, a clamping plate is fixedly connected to one side of the unloaded bar switch, and the clamping plate is adapted to the first guide groove.

[0006] By adopting the above technical solution, through the first guide groove fixedly connected to the bottom side of the tank cover, and the adaptive design of the card plate fixedly connected to the unloaded strip switch, the new unloaded strip switch fixing structure can achieve stable fixation of the switch, effectively preventing the switch from shaking or shifting during use, thereby improving the safety and reliability of the equipment.

[0007] At the same time, compared with the traditional hand hole and bolt fixing method, this design reduces the potential risk points of oil leakage and reduces the processing cost. The simple design of the fixing structure also makes the installation, replacement and maintenance of the switch more convenient and quick, thereby improving work efficiency.

[0008] Furthermore, a guide plate is fixedly connected to the bottom of the first guide groove, and the guide plate is arranged obliquely.

[0009] By adopting the above technical solution, a guide plate is fixedly connected to the bottom of the first guide groove, and the guide plate is arranged obliquely to provide a clear insertion path for the card plate. When installing a switch without a load bar, the card plate can slide smoothly into the first guide groove along the inclined surface of the guide plate, thereby simplifying the installation process.

[0010] At the same time, the obliquely arranged guide plate also plays a guiding role, which can help align the card plate and the first guide groove during installation, avoiding deviation and friction during the installation process, thereby protecting the surface of the card plate and the first guide groove and extending the service life.

[0011] Furthermore, a bolt is fixedly connected to the front side of the load-free switch, and a plurality of bolts are provided.

[0012] By adopting the above technical solution, the front side of the load-free switch is fixedly connected with multiple bolts, which increases the connection points between the load-free switch and other components, making the fixation of the switch more stable and reliable. The tightening effect of multiple bolts can effectively prevent the connection between the load-free switch and other components from loosening or shifting during use, thereby improving the stability of the entire fixed structure.

[0013] At the same time, the setting of multiple bolts enhances the safety and durability of the unloaded strip switch fixing structure, providing a guarantee for the long-term stable operation of the equipment.

[0014] Furthermore, both the front and rear sides of the first guide groove are fixedly connected with a clamping rod, and both sides of the clamping plate are provided with a first clamping groove, and the first clamping groove and the clamping rod are arranged opposite to each other.

[0015] By adopting the above technical solution, by fixing the connecting rod on the front and rear sides of the first guide groove, and the relative setting of the first slot on the card plate, an additional fixing mechanism is provided for the switch without a carrier strip. When the card plate is obliquely inserted along the first guide groove, the connecting rod will be embedded in the corresponding first slot, thereby realizing the lateral locking of the switch without a carrier strip.

[0016] At the same time, the matching design of the clamping rod and the first clamping slot not only enhances the fixing stability of the load-free switch, but also effectively prevents it from lateral movement or falling out during use, further improving the safety and reliability of the device.

[0017] Furthermore, a second guide groove is fixedly connected to one side of the bottom of the fuel tank cover, and a locking mechanism is fixedly connected to one side of the non-load bar switch.

[0018] By adopting the above technical solution, the second guide groove on one side of the bottom of the tank cover provides a stable installation position for the snap-fit ​​mechanism, ensuring that the snap-fit ​​mechanism can be accurately connected to the tank cover, so that the load-free switch can be firmly fixed on the tank cover through the snap-fit ​​mechanism, thereby improving the stability and reliability of the entire fixed structure.

[0019] At the same time, the combination of the locking mechanism and the second guide groove has certain adjustment and disassembly convenience, which provides convenience for subsequent maintenance and replacement.

[0020] Furthermore, a second clamping slot is provided inside the second guide slot, and two second clamping slots are provided, and the two second clamping slots are arranged in a mirror image.

[0021] By adopting the above technical solution, by opening two second card slots in mirror-image arrangement inside the second guide slot, a stable card contact point is provided for the card mechanism, so that the card mechanism can be firmly inserted into the second card slot, thereby enhancing the fixing effect of the stripless switch.

[0022] At the same time, the two second card slots arranged in mirror image can simultaneously card-connect the sliding blocks, ensuring that the load-free switch can be accurately fixed in the predetermined position, thereby improving the installation efficiency and ensuring the stability and reliability of the fixed structure.

[0023] Furthermore, a reinforcement ring is fixedly connected to the bottom of the second guide groove.

[0024] By adopting the above technical solution, the structural strength of the second guide groove is enhanced by fixing a reinforcement ring at the bottom of the second guide groove. The reinforcement ring can effectively disperse and bear the load from the unloaded switch and its fixed structure, preventing deformation or damage caused by long-term use or external force.

[0025] At the same time, the reinforcement ring ensures that the load-free switch always remains stable during use, thereby ensuring the safe operation of the equipment and extending its service life.

[0026] Furthermore, the engaging mechanism comprises a mounting plate, a mounting groove is formed on the mounting plate, and a rotating rod is rotatably connected to the interior of the mounting groove via a torsion shaft.

[0027] By adopting the above technical solution, the mounting plate in the locking mechanism provides a stable foundation for installing and fixing other components, the mounting groove opened thereon provides an installation space for the rotating rod, and the flexible rotation of the rotating rod is realized through the torque shaft.

[0028] At the same time, the design of the rotating rod enables the locking mechanism to have a certain adjustment ability. By rotating the rotating rod, the locking and unlocking states of the locking mechanism can be conveniently adjusted, which improves the convenience of installation and enhances the applicability and flexibility of the locking mechanism.

[0029] Furthermore, both upper and lower sides of the rotating rod are rotatably connected to connecting rods, and one end of the connecting rod is rotatably connected to a sliding block.

[0030] By adopting the above technical solution, a linkage mechanical structure is formed by rotating the connecting rod on the upper and lower sides of the rotating rod, and the connecting rod is then rotatably connected to the sliding block. When the rotating rod rotates, the sliding block can be driven to slide inside the installation groove through the transmission action of the connecting rod, thereby realizing the locking and unlocking operation of the locking mechanism.

[0031] At the same time, this linkage mechanical structure design not only makes the operation easier and faster, but also improves the stability and reliability of the locking mechanism.

[0032] Furthermore, clamping blocks are fixedly connected to the front and rear sides of the mounting plate.

[0033] By adopting the above technical solution, by fixing the connecting blocks on the front and rear sides of the mounting plate, the contact area and friction between the locking mechanism and the reinforcing ring are increased, thereby improving the fixing stability of the load-free switch.

[0034] The engaging mechanism can be more closely fitted inside the second guide groove, effectively preventing the switch without a load bar from loosening or shifting during use.

[0035] In summary, the utility model mainly has the following beneficial effects:

[0036] 1. The utility model realizes technical foolproofing by setting the first guide groove and the card plate, avoids the risk of oil leakage caused by human operation errors, and thus ensures the safety and reliability of the equipment. This design not only simplifies the installation steps, but also reduces the manufacturing cost, because its structure is simple and does not require complicated manual operation or additional seals, further improving the practicality and economic benefits;

[0037] 2. The utility model provides a clear insertion path for the card plate by setting the guide plate, thereby simplifying the installation process, so that the card plate can be inserted into the first guide groove more smoothly and accurately, reducing the friction and resistance during installation, protecting the surface of the card plate and the first guide groove, extending the service life, and improving the stability and durability of the entire fixing structure;

[0038] 3. The utility model sets a locking mechanism. During the installation process, the state of the locking mechanism can be easily adjusted by rotating the rotating rod to adapt it to the installation requirements, thereby improving the installation efficiency. When the mounting plate is pushed into the second guide groove, the rotating rod is released, and the rotating rod automatically resets under the rotation of the torque shaft, pushing the sliding block to be locked into the second slot to achieve a firm locking. This not only makes the installation of the load-free switch more secure and reliable, but also improves the safety of the entire device and the convenience of installation.
