[0002] Dynamic voltage restorer, abbreviated as DVR in English, actually refers to a series compensation device with an energy storage device (system). However, it does not have reactive power, but has the ability to compensate for active power. Modern power electronics technology can control the quality of power during operation. The dynamic voltage restorer is mainly composed of a control box, an energy storage unit and a dry-type transformer.

[0003] At present, the dynamic voltage restorer is mainly installed in a rack. A protective cabinet is provided on the outside of the rack. When in use, the dynamic voltage restorer is operated by opening the cabinet door. Due to the small space inside the cabinet, the movement of tools inside the cabinet is limited when disassembling and assembling the dynamic voltage restorer, which makes it inconvenient to disassemble and assemble the dynamic voltage restorer. Therefore, a dynamic voltage restorer that is easy to disassemble and assemble is needed to meet the usage requirements. Utility Model Content

After the disassembly and assembly are completed, the reciprocating screw rod 64 continues to rotate to drive the frame 2, the control box 3, the energy storage unit 4 and the dry-type transformer 5 into the cabinet 1. At this time, the clamping rod 612 can be pulled outward so that the clamping rod 612 and the plug rod 610 are no longer engaged. When the bar seat 68 is needed, the sliding hole 618 can be directly removed from the connecting seat 67 to save space. When the strip seat 68 is needed, the positioning rod 614 can be directly inserted into the connecting seat 67. At this time, the insertion rod 610 will also be inserted into the connecting seat 67.

When the card rod 612 coincides with the card slot 611, the card rod 612 can be driven to be stuck in the card slot 611 under the action of the fixing spring 613 to fix the bar seat 68. The rotation of the heat dissipation fan 74 will accelerate the air flow, blow the heat generated by the dynamic voltage restorer out of the cabinet 1, and dissipate the heat of the dynamic voltage restorer. The dustproof net 72 and the louver blades 75 can prevent dust from entering the cabinet 1. When the heat dissipation fan 74 is working, the louver blades 75 will be blown up without affecting the air circulation. When the heat dissipation fan 74 is not working, the louver blades 75 will automatically overlap under the action of gravity to play a dustproof role.
