Description

Technical Field

[0001] The present invention relates to the technical field of active power filter equipment, and particularly to an active power filter equipment convenient for maintenance. Background Technique

[0002] The active power filter equipment is an advanced power harmonic control equipment made by adopting modern power electronic technology and digital signal processing technology. Its main functions and purposes are to eliminate harmonic currents in the power system, improve power quality, suppress voltage fluctuations, thereby protecting power grid equipment and extending its service life.

[0003] This active power filter equipment convenient for maintenance mainly consists of an instruction current operation circuit and a compensation current generation circuit. The voltage and current signals of the compensation object are detected by a mutual inductor, and after being converted and processed, they are sent to the control system to calculate the instruction signal of the compensation current. Subsequently, this signal is amplified by the compensation current generation circuit to generate a compensation current with the same amplitude and opposite polarity as the grid harmonic current and inject it into the grid, thereby realizing the compensation or cancellation of harmonic currents.

[0004] In the existing equipment design, the active power filter module and components such as the control panel are usually installed in a cabinet composed of a framework. Although this design enhances the structural stability and protection of the equipment to a certain extent, it also brings maintenance problems. Due to the obstruction of the framework, when the staff opens the cabinet for maintenance, they often need to remove the equipment for repair, which is rather cumbersome. In view of this, we propose an active power filter equipment convenient for maintenance. Summary of the Invention

[0021] 1. To make the maintenance of the device more convenient and efficient, a maintenance component is provided. This component cooperates with the opening of the door panel to open the buckle structure, thereby opening the side panel. Meanwhile, in daily life, the motor drives the fan to rotate, and through the hollow vertical rod, hollow horizontal rod, circular opening, loop groove, air intake groove, and long groove, the filtering device can be cooled better, thereby reducing the maintenance frequency of the device.

[0022] 2. To make the device more flexible, a trigger component is provided.

Meanwhile, when the side is opened, the arc button is released, causing the motor to stop rotating. Also, when the temperature inside the device rises, the thermal expansion airbag starts to expand, squeezing the small spring rod, causing the circular plate to squeeze the trigger button, and thus starting the motor.

[0023] 3. To prevent excessive dust from entering the device, a dust-proof component is provided. This component cooperates with the motor to drive the fan to rotate and drive the airflow into the device. Then, the herringbone filter plate blocks the dust, causing the dust to fall into the collection boxes on both sides, and thus onto the pressing plate. Meanwhile, through the cover plate, the dust will not fly around after entering the collection box. When the dust reaches a certain weight, the moving electrode plate triggers the fixed electrode plate, causing the dust suction pump to start and remove the dust.

[0024] 4. To make the opening of the side panel of the device smoother, a support component is provided. This component cooperates with the round block to squeeze the thick spring, causing the cylindrical shell to squeeze the universal wheel, so that the side panel has better stability during movement. Also, after moving to the appropriate position, the side panel can be relatively stable without other supports. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, after moving to a suitable position, the side plate 37 can be relatively stable without other supports.

[0041] Working principle: During use, when the temperature inside the device rises, the thermal expansion airbag 59 starts to expand, which cooperates with the baffle 511 to make the thermal expansion airbag 59 push the circular plate 58 to squeeze the small spring rod 56, so that the circular plate 58 squeezes the trigger button 57, thereby starting the motor 314. The motor 314 drives the fan 315 to rotate, and then through the hollow vertical rod 31, the hollow cross rod 32, the circular opening 33, the return groove 316, the air intake groove 317 and the long groove 318, the filtering device is cooled better. When the circular plate 58 squeezes the trigger button 57, it drives the electric slide rail 319, so that the long plate 320 starts to move, so that the small opening 321 coincides with the large opening 325, so that the air pressure is enhanced, so that the cooling effect is better. At the same time, the dust falls to the bottom dust drawer 35 for collection, so that the maintenance frequency of the device is reduced. When maintenance is required, cooperate to open the door panel 310 to loosen the circular button 54, so that the rotation speed of the motor 314 slows down, so as to open the buckle structure 51, make the side plate 37 start to move, so that the arc button 53 is loosened, so that the motor 314 stops rotating, so as to take out tools from the tool drawer 324 for maintenance. At the same time, cooperate with the motor 314 to drive the fan 315 to rotate to drive the air flow into the device, so that the herringbone filter plate 64 blocks the dust, so that the dust falls into the two side collection boxes 62, so that the dust falls onto the pressing plate 69. At the same time, through the cover plate 63, the dust will not fly around after entering the collection box 62. When the dust reaches a certain weight, the moving electrode plate 611 triggers the fixed electrode plate 610, so that the dust suction pump 67 is started, and the dust is removed through the round tube 66 and the square tube 65. At the same time, cooperate with the round block 71 to squeeze the thick spring 72, so that the cylindrical outer shell 73 squeezes the universal wheel 74, so that the side plate 37 has better stability when moving, and at the same time, after moving to the appropriate position, the side plate 37 can be relatively stable without other supports.

[0042] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements without departing from the spirit of the present invention are all within the protection scope of the present invention.
