Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage SVG static var generators, and particularly to an installation and fixing device for a low-voltage SVG static var generator. Background Art

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

[0003] When it is necessary to install a low-voltage SVG static var generator on a wall at a certain height, the existing installation method directly fixes the low-voltage SVG static var generator on the wall through bolts, which is not convenient for the later replacement and maintenance of the low-voltage SVG static var generator; at the same time, after installing the low-voltage SVG static var generator, it is connected to multiple wires, and the wires cannot be classified and managed, which is not convenient for troubleshooting. Summary of the Invention

[0004] The problem solved by the present invention is to provide an installation and fixing device for a low-voltage SVG static var generator, which solves the technical problems that when it is necessary to install a low-voltage SVG static var generator on a wall at a certain height, the existing installation method directly fixes the low-voltage SVG static var generator on the wall through bolts, which is not convenient for the later replacement and maintenance of the low-voltage SVG static var generator; at the same time, after installing the low-voltage SVG static var generator, it is connected to multiple wires, and the wires cannot be classified and managed, which is not convenient for troubleshooting.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An installation and fixing device for a low-voltage SVG static var generator, including an installation plate, a placement seat, a limiting mechanism, and a wiring mechanism. A placement seat is installed on the side wall of the installation plate, and a number of limiting mechanisms are installed on the top side of the placement seat;

[0007] A through groove is opened on one side of the installation plate, a wire groove is opened on the opposite side of one side of the installation plate, and the wire groove is connected to the through groove. A limiting plate is installed on the bottom side of the installation plate, and a number of wiring mechanisms are installed on the limiting plate;

[0008] The limiting mechanism includes a cylinder body and a movable rod. The cylinder body penetrates through the mounting plate. A bottom hole is formed in the middle of the bottom side of the cylinder body. A limiting ring is installed on the inner side wall of the cylinder body. A movable rod is installed through the inside of the cylinder body. A retaining ring is installed on the outside of the movable rod and inside the cylinder body. A buffer seat is installed at the top of the movable rod outside the cylinder body. A first spring is sleeved on the outside of the movable rod and inside the cylinder body;

[0009] The wiring mechanism includes a fixed buckle and a movable buckle. The top sides of the fixed buckles are all connected to the bottom side of the limiting plate, and a movable buckle is installed below the fixed buckles. A telescopic rod penetrates through the limiting plate. A retaining seat is installed at the top of the telescopic rod. A second spring is sleeved on the outside of the telescopic rod between the retaining seat and the limiting plate. A connecting plate is installed at the bottom end of the telescopic rod. The connecting plate is connected to the movable buckle.

[0010] Preferably, mounting groove holes are formed at the four corners of the mounting plate, and the shape of the placing seat is U-shaped.

[0011] Preferably, the shape of the limiting plate is L-shaped, and the shapes of the fixed buckle and the movable buckle are both semi-circular, and the fixed buckle and the movable buckle are symmetrical.

[0012] Preferably, the inner diameter of the bottom hole is the same as the outer diameter of the movable rod, and the outer diameter of the first spring is smaller than the inner diameter of the limiting ring.

[0013] Preferably, rubber pads are pasted on the bottom side of the fixed buckle and the top side of the movable buckle.

[0014] Preferably, the low-voltage SVG static var generator is limited between several limiting mechanisms, and the connecting wires are limited and distributed through the wiring mechanism.

[0015] Preferably, the specific operation steps of this installation and fixing device are as follows:

[0016] Step 1: Install the mounting plate on the wall by passing bolts through the mounting groove holes. At this time, place the low-voltage SVG static var generator between several limiting mechanisms on the placing seat. The bottom sides of different low-voltage SVG static var generators are in contact with different numbers of limiting mechanisms. At this time, the buffer seat drives the movable rod to move downward in the cylinder body under the weight of the low-voltage SVG static var generator. At this time, the bottom end of the movable rod penetrates through the bottom hole, and the retaining ring moves downward to compress the first spring until the retaining ring is blocked and limited by the limiting ring. At this time, the low-voltage SVG static var generator is embedded between several limiting mechanisms to achieve fixation;

[0017] Step 2: The connecting wires of the low-voltage SVG static var generator pass through the through slots and wire grooves. When passing through the wiring mechanism of the limit plate, according to the types of the wires, pull down the movable buckles respectively. The connecting plate on the movable buckle drives the telescopic rod to move downward, compressing the second spring through the retaining seat. At this time, place the wire between the fixed buckle and the movable buckle, release the movable buckle, and the second spring returns to its original state. At this time, the fixed buckle and the movable buckle contact to limit and clamp the wire.

[0018] The beneficial effects of the present invention are as follows: Place the low-voltage SVG static var generator between several limiting mechanisms on the placement seat. The bottom sides of different low-voltage SVG static var generators contact different numbers of limiting mechanisms. At this time, the buffer seat drives the movable rod to move downward in the cylinder under the weight of the low-voltage SVG static var generator. At this time, the bottom end of the movable rod penetrates the bottom hole, and the retaining ring moves downward to compress the first spring until the retaining ring is blocked and limited by the limiting ring. At this time, the low-voltage SVG static var generator is embedded between several limiting mechanisms to achieve fixation. When the low-voltage SVG static var generator is removed, through the first spring, the limiting mechanism automatically resets, which is convenient for quickly installing and fixing the low-voltage SVG static var generator, facilitating subsequent replacement and maintenance, and facilitating the installation and fixation of the low-voltage SVG static var generator with an irregular shape.

[0019] When the connecting wires of the low-voltage SVG static var generator pass through the wiring mechanism of the limit plate, according to the types of the wires, pull down the movable buckles respectively. The connecting plate on the movable buckle drives the telescopic rod to move downward, compressing the second spring through the retaining seat. At this time, place the wire between the fixed buckle and the movable buckle, release the movable buckle, and the second spring returns to its original state. At this time, the fixed buckle and the movable buckle contact to limit and clamp the wire, which is convenient for classifying and fixing the wires. Description of the Drawings

[0038] As an embodiment of the present invention, the specific operation steps of the installation and fixing device are as follows:

[0039] Step 1: Install the mounting plate 1 on the wall through the mounting slot holes 4 with bolts. At this time, place the low-voltage SVG static var generator between several limiting mechanisms 3 on the placing seat 2.

At this time, the fixed buckle 16 and the movable buckle 17 contact to limit and clamp the wire.

[0041] Place the low-voltage SVG static var generator between several limiting mechanisms 3 on the placement seat 2. The bottom sides of different low-voltage SVG static var generators are in contact with different numbers of limiting mechanisms 3. At this time, the buffer seat 13 drives the movable rod 12 to move downward in the cylinder 9 under the weight of the low-voltage SVG static var generator. At this time, the bottom end of the movable rod 12 penetrates the bottom hole 10, and the retaining ring 14 moves downward to compress the first spring 15 until the retaining ring 14 is blocked and limited by the limiting ring 11. At this time, the low-voltage SVG static var generator is embedded between several limiting mechanisms 3 to achieve fixation.

[0042] When the connecting wires of the low-voltage SVG static var generator pass through the wiring mechanism 8 of the limiting plate 7, according to the types of the wires, pull down the movable buckle 17 respectively. The connecting plate 18 on the movable buckle 17 drives the telescopic rod 19 to move downward, compressing the second spring 21 through the retaining seat 20. At this time, place the wire between the fixed buckle 16 and the movable buckle 17, and release the movable buckle 17. The second spring 21 returns to its original state. At this time, the fixed buckle 16 and the movable buckle 17 come into contact to limit and clamp the wire, facilitating the classification and fixation of the wires.
