Description

Technical Field

[0001] The invention relates to the technical field of high-voltage SVG static reactive generators, and in particular to a high-voltage SVG static reactive generator installation and fixing device. Background Art

[0002] Static VAR generators can be divided into voltage type and current type. They can provide both lagging reactive power and leading reactive power. The basic principle of SVG is to connect the self-commutated bridge circuit to the power grid through a reactor or directly in parallel. By properly adjusting the phase and amplitude of the output voltage on the AC side of the bridge circuit, or directly controlling the AC side current, the circuit can absorb or emit reactive current that meets the requirements, thereby achieving the purpose of power reactive compensation. According to the difference in high and low voltage, it can be divided into low-voltage SVG static VAR generator and high-voltage SVG static VAR generator.

[0003] When the high-voltage SVG static VAR generator needs to be installed on the wall, the high-voltage SVG static VAR generator needs to be lifted and then installed and fixed. This installation method is complicated to operate and has certain safety hazards, and is not convenient for subsequent maintenance and replacement. Summary of the invention

[0019] When the lifting platform falls rapidly, the rack moves down until the baffle at the top contacts the buffer seat. At this time, the buffer seat drives the movable rod to move in the built-in groove, driving the limit slider to compress the spring, and plays a buffering role through the elastic deformation of the spring, which plays a role of safety protection and ensures the installation and use of the device.

[0036] As an embodiment of the present invention, the specific operation steps of the installation and fixing device are as follows:

[0037] Step 1: The lifting platform 11 of the lifting mechanism 2 descends to the bottom, and the high-voltage SVG static reactive generator is placed on the lifting platform 11. At this time, the second servo motor 14 drives a rotating tooth 13 in the installation slot 15 to rotate, and then drives another rotating tooth 13 to rotate.

At this time, the buffer seat 21 drives the movable rod 19 to move in the built-in groove 18, driving the limit slider 20 to compress the spring 22, and the elastic deformation of the spring 22 plays a buffering role.

[0040] The high-voltage SVG static reactive generator is placed on the lifting platform 11. At this time, the second servo motor 14 drives a rotating tooth 13 in the installation groove 15 to rotate, and then drives the other rotating tooth 13 to rotate. The two rotating tooth 13 seats rotate in opposite directions at the same speed, and then drive the meshing rack 17 to move up along the second slide rail through the second slide groove, and drive the lifting platform 11 to move up along the fixed cross bar 12 through the first slide rail. When the lifting platform 11 rises between the two clamping plates 5 of the installation frame 1, the pneumatic rod 4 on the first mounting frame 3 is extended to drive the clamping plate 5 to approach the high-voltage SVG static reactive generator until the high-voltage SVG static reactive generator is clamped by the clamping plate 5. Then, the first servo motor 9 installed on the fixed seat 7 on the second mounting frame 6 drives the rotating arm 10 to rotate until the two limit rotating plates 8 are level with the outside of the high-voltage SVG static reactive generator, which acts as a limit seat for the high-voltage SVG static reactive generator, thereby realizing the rapid installation and fixation of the high-voltage SVG static reactive generator, facilitating operation, and facilitating subsequent maintenance and replacement.

[0041] When the lifting platform 11 falls rapidly, the rack 17 moves down until the baffle 16 at the top contacts the buffer seat 21. At this time, the buffer seat 21 drives the movable rod 19 to move in the built-in groove 18, driving the limit slider 20 to compress the spring 22.
