[0015] A method for using a reactive power compensation device convenient for maintenance includes the following steps: Step 1: When the equipment needs to be maintained, open the first cabinet door to maintain the equipment. At the same time, when the first cabinet door rotates, it drives the fixed plate to rotate. When the first cabinet door rotates away from the limit of the card slot, the elastic telescopic rod drives the card slot to move upward by its own elastic force; Step 2: The card slot moves upward to hold the fixed plate, and the card slot limits the fixed plate to prevent the first cabinet door from suddenly closing due to wind force or collision during the maintenance process, which may cause the maintenance personnel being pinched and affect the maintenance of the maintenance personnel; Step 3: Pull the pull rod to move downward. When the pull rod moves downward, it pushes the rotating plate to rotate downward. When the rotating plate is separated from the pull rod, the first torsion spring drives the rotating plate to reset. At the same time, the limiting plate contacts the sliding frame, and the sliding frame blocks the limiting plate to prevent the rotating plate from rotating upward, eliminating the need to keep holding the pull rod by hand, which is convenient to operate; Step 4: The sliding frame moves away from the pull rod to drive the rotating plate to release the limit on the pull rod. The elastic telescopic rod drives the card slot to reset by its own elastic force. The reset of the card slot facilitates future maintenance and improves the maintenance efficiency and safety of the equipment.

[0016] The present invention provides a reactive power compensation device convenient for maintenance and its method. It has the following beneficial effects: (1)In this invention, the fixing plate is limited by the clamping groove to prevent the first cabinet door from suddenly closing due to wind force or collision during maintenance, which may cause the hands of the maintenance personnel being clamped and affect the maintenance work. At the same time, the limiting plate will contact the sliding frame, and the sliding frame will block the limiting plate to prevent the rotating plate from rotating upward, eliminating the need to constantly hold the pull rod by hand, which is convenient for operation. When the sliding frame moves away from the pull rod, it will drive the rotating plate to release the limit on the pull rod, and the elastic telescopic rod's own elastic force will drive the clamping groove to reset. The reset of the clamping groove facilitates future maintenance, improving the maintenance efficiency and safety of the equipment.

[0017] (2)In this invention, when the sliding seat resets, it will drive the hollow rod and the sealing ring to drain through the liquid inlet hole, and the liquid will flow out slowly, preventing the first cabinet door from being damaged due to excessive force when closing it. When the support seat moves towards the second cabinet door, it will drive the rotating plate to move towards the second cabinet door, and the rotating plate moving towards the second cabinet door will push the fixed seat and the second cabinet door to rotate. During maintenance, the first cabinet door and the second cabinet door can be opened simultaneously to repair the inside of the chassis, enabling the maintenance personnel to perform maintenance on the inside of the chassis from two directions at the same time, improving the maintenance efficiency.

[0018] (3)In this invention, when the turntable rotates upward, it will drive the turntable to rotate downward, and the turntable rotating downward will drive the conductive rod to rotate downward. When the conductive rod rotates downward and touches the ground, it can prevent static electricity from damaging electronic components during the maintenance process. At the same time, when the push block moves downward, it will push the rotating plate to open, and the rotating plate can prevent moisture at the bottom from entering the inside of the chassis, causing equipment short - circuit. At the same time, the rotating plate provides protection for the conductive rod, extending the service life of the conductive rod. BRIEF DESCRIPTION OF THE DRAWINGS
