Description

Technical Field

[0001] This utility model relates to the field of phase advancers, and more particularly to a variable load phase advancer with a buffer structure. Background Technology

[0002] A variable load phase advancer (also known as a phase advancer or phase regulator) is a device used to adjust the phase of the electrical load in a power system. Variable load phase advancers with a buffer structure are usually used to improve the stability of the power system and prevent oscillations caused by load changes.

[0003] According to the published intelligent electronic soft phase advancer (publication number: CN201204469Y), it includes a primary control circuit consisting of a circuit breaker, thermal overload relay, AC contactor, rectifier transformer, and AC-DC-AC inverter. The three output terminals of the AC-DC-AC inverter are connected in series with the corresponding rotor circuits of the main motor via a phase advance switching contactor and a Hall sensor, respectively. The output terminal of the phase advance switching contactor is connected to the starter cabinet via a starter switching contactor. It consists of a phase advance indicator circuit, a phase retreat indicator circuit, a phase advance interlocking circuit, a phase advance and phase retreat circuit, a phase advance contactor circuit, and a starter contactor circuit.

[0004] In the aforementioned application, the cooperation between components such as AC contactors and rectifier transformers is insufficient to effectively prevent interference with the wires and ensure stable operation of the equipment under varying loads, resulting in reduced safety and reliability during equipment use, which requires improvement.

This utility model proposes a variable load phase advancer with a buffer structure, which solves the problem that the existing technology cannot effectively prevent the wires from being interfered with and cannot ensure the stable operation of the equipment during load changes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a variable load phase advancer with a buffer structure, including a phase advancer, a movable door rotatably connected to the side of the phase advancer, a protective component provided on the side of the phase advancer, the protective component including a connecting pipe, one end of the connecting pipe passing through the side of the phase advancer, an electric wire passing through the side of the connecting pipe, a rotating rod rotatably connected to the side of the phase advancer, a protective cover fixedly connected to the circumference of the rotating rod, a gear fixedly connected to the end of the rotating rod away from the phase advancer, a horizontal plate fixedly connected to the side of the phase advancer, a rack slidably connected to the bottom of the horizontal plate, a rectangular rod fixedly connected to the side of the phase advancer, an electric telescopic rod fixedly connected to the side of the rectangular rod, one end of the electric telescopic rod fixedly connected to the side of the rack.

[0007] Preferably, the rack and pinion mesh with each other, the protective cover is located above the connecting pipe and the wire, and the top of the electric telescopic rod is equipped with a switch. The design of the protective cover can cover the connecting pipe and the wire for protection, which is beneficial to protect the connection between the connecting pipe and the wire, and makes the phase advancer buffering effect better.

[0008] Preferably, the connecting pipe and the wire are located on the displacement trajectory of the protective cover. The side of the protective cover has a groove located above the wire. The groove design helps to fit the wire and prevents the wire from getting stuck, thus affecting the normal use of the equipment.

A short rod is fixedly connected to the circumference of the rotating shaft. A shaped rod is fixedly connected to the side of the rack. A pressing rod is fixedly connected to the side of the shaped rod. The pressing rod moves the short rod, causing the rotating shaft to rotate.

In addition, through the cooperation of components such as the fan blades, short rods, and rotating shaft inside the automatic heat dissipation assembly, the fan blades rotate to generate airflow, which carries away the heat inside the phase advancer, preventing the equipment from malfunctioning or degrading due to overheating. Good heat dissipation can keep the equipment within the ideal operating temperature range, and airflow cooling helps to reduce the negative effects of overheating, thereby improving the overall equipment efficiency and ensuring its efficient adjustment of phase and load changes.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] According to one embodiment of the present invention, in conjunction with Figures 1-5 A variable load phase advancer with a buffer structure is shown, including a phase advancer 1. A movable door 2 is rotatably connected to the side of the phase advancer 1. A protective component 3 is provided on the side of the phase advancer 1. The protective component 3 includes a connecting pipe 31, one end of which passes through the side of the phase advancer 1. An electric wire 32 passes through the side of the connecting pipe 31. A rotating rod 33 is rotatably connected to the side of the phase advancer 1. A protective cover 34 is fixedly connected to the circumference of the rotating rod 33. A gear 35 is fixedly connected to the end of the rotating rod 33 away from the phase advancer 1. A horizontal plate 36 is fixedly connected to the side of the phase advancer 1. A rack 37 is slidably connected to the bottom of the horizontal plate 36. A rectangular rod 38 is fixedly connected to the side of the phase advancer 1. An electric telescopic rod 39 is fixedly connected to the side of the rectangular rod 38. One end of the electric telescopic rod 39 is fixedly connected to the side of the rack 37.

[0024] The rack 37 and gear 35 mesh with each other. The protective cover 34 is located above the connecting pipe 31 and the wire 32. The top of the electric telescopic rod 39 is equipped with a switch 310. The design of the protective cover 34 can cover the connecting pipe 31 and the wire 32 for protection, which is beneficial to protect the connection between the connecting pipe 31 and the wire 32, making the buffering effect of the phase advancer 1 better.

[0025] The connecting pipe 31 and the wire 32 are located on the displacement trajectory of the protective cover 34. The protective cover 34 has a slot 313 on its side, which is located above the wire 32. The design of the slot 313 is conducive to fitting the wire 32 and preventing the wire 32 from getting stuck, thus affecting the normal use of the equipment.

[0026] A limiting groove 311 is provided on the side of the horizontal plate 36. A slide rod 312 is slidably connected to the inner wall of the limiting groove 311. The end of the slide rod 312 away from the limiting groove 311 is fixedly connected to the side of the rack 37. The design of the limiting groove 311 and the slide rod 312 can limit the rack 37 and prevent the movement trajectory of the rack 37 from deviating.

[0027] An automatic heat dissipation assembly 4 is provided on the side of the phase advancer 1. The automatic heat dissipation assembly 4 includes a support rod 41, one end of which is fixedly connected to the side of the phase advancer 1. A rotating shaft 42 is rotatably connected to the side of the support rod 41. A fan blade 43 is fixedly connected to the circumference of the rotating shaft 42. A short rod 45 is fixedly connected to the circumference of the rotating shaft 42. A shaped rod 46 is fixedly connected to the side of the rack 37. A pressing rod 47 is fixedly connected to the side of the shaped rod 46. The pressing rod 47 moves the short rod 45, causing the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the fan blade 43 to rotate. The rotation of the fan blade 43 generates airflow to dissipate heat from the inside of the phase advancer 1, preventing overheating during use and buffering, which would affect its operation.

[0028] The short rod 45 is located on the displacement trajectory of the extrusion rod 47, and the fan blade 43 is located inside the phase advancer 1. Several fan blades 43 are provided and are arranged in a circumferential array on the circumferential surface of the rotating shaft 42. The fan blades 43 are designed to rotate inside the phase advancer 1 to generate wind power and dissipate heat from the inside of the phase advancer 1.

[0029] A torsion spring 44 is fixedly connected to the circumferential surface of the rotating shaft 42. The end of the torsion spring 44 away from the rotating shaft 42 is fixedly connected to the side of the support rod 41. The design of the torsion spring 44 allows the rotating shaft 42 to automatically reset when it is not compressed and rotated, making it convenient for secondary use.

[0030] The phase advancer 1 is equipped with a controller 5 and a capacitor 6. There are two movable doors 2, which are symmetrical about each other along the vertical central axis of the phase advancer 1. The design of the movable doors 2 makes it easy to open the phase advancer 1 for operation.

[0031] In this embodiment, the phase advancer 1, by adding an intermediate link, a buffer circuit or control system, can more smoothly adjust the phase difference between the power supply and the load, enabling the phase advancer 1 to adapt to dynamic changes in the load and reduce the impact of fluctuations on the system. Capacitors 6 are used to filter and regulate the signal, reducing the speed and amplitude of the system response, thereby avoiding overreaction. When in use, the phase advancer 1 typically needs to be connected to the phase difference device between the power supply and the load via wire 32. To provide a good operating environment for the phase advancer 1, the telescopic end of the electric telescopic rod 39 extends towards the side closer to the connecting pipe 31. The extension of the telescopic end of the electric telescopic rod 39 drives the rack 37 to move at the bottom of the horizontal plate 36, moving the rack 37 towards the side closer to the connecting pipe 31. The rack 37 and gear 35 mesh with each other; the movement of the rack 37 drives the gear 35 to rotate, which in turn drives the rotating rod 33 to rotate. The rotation of the rotating rod 33 drives the protective cover 34 to rotate, causing the protective cover 34 to rotate towards the top of the connecting pipe 31 and the wire 32. The connection between the connecting pipe 31 and the wire 32 is covered by a protective cover 34. The slot 313 corresponds to the wire 32, but it will not jam the wire 32 and will not affect the normal use of the equipment. By adding a buffer circuit or control system, the phase advancer 1 can more smoothly adjust the phase difference between the power supply and the load. In this way, the system can adapt to the dynamic changes of the load, avoid the violent reaction caused by load fluctuations, and ensure the stable operation of the system. The design of the protective cover 34 can effectively protect the connection between the connecting pipe 31 and the wire 32, preventing external interference, dust or other physical damage from affecting the normal operation of the electrical connection. By covering the connection, the wire 32 is prevented from being directly affected by external factors, improving the reliability and stability of the equipment. The connection of the wire 32 is effectively protected, which can reduce the impact of vibration and impact on the equipment during load changes, help the phase advancer 1 to adjust smoothly when the load changes, effectively prevent interference from the wire 32, ensure the stable operation of the equipment during load changes, thereby extending the service life of the equipment and improving its safety and reliability.

[0032] The telescopic end of the aforementioned electric telescopic rod 39 extends towards the side closer to the connecting pipe 31, causing the rack 37 to move towards the side closer to the connecting pipe 31. The movement of the rack 37 causes the irregular rod 46 and the pressing rod 47 to move. The short rod 45 is located on the movement trajectory of the pressing rod 47. When the pressing rod 47 moves, it will press against the short rod 45. The short rod 45 will be displaced due to the pressure, thereby driving the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 will drive the fan blade 43 to rotate, and the rotation of the fan blade 43 will generate wind. The fan blade 43 is located inside the phase advancer 1. The airflow generated by the rotation of fan blade 43 will blow into the interior of phase advancer 1 to dissipate heat. When phase advancer 1 is running during the buffering process, the internal temperature may rise due to load changes, equipment operation, and other factors. The airflow generated by fan blade 43 will carry away the heat inside phase advancer 1, preventing the equipment from malfunctioning or degrading due to overheating. Good heat dissipation can keep the equipment within the ideal operating temperature range. Airflow cooling helps to reduce the negative effects of overheating, thereby improving the overall equipment efficiency and ensuring its efficient adjustment of phase and load changes.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
