Description

Technical Field

[0001] This utility model relates to devices in the field of static var generator aging test racks, and more particularly to a static var generator aging test rack. Background Technology

[0002] A static var generator (SVA) is a self-commutated bridge circuit connected to the power grid via a reactor or directly in parallel. By adjusting the phase and amplitude of the AC output voltage of the bridge circuit, or by directly controlling its AC current, the circuit can absorb or generate reactive power that meets the requirements, thus achieving dynamic reactive power compensation. When testing the aging of a static var generator, a storage test rack is required to place it.

[0003] Based on a search of existing patents, the inventors found the following problems in the existing technology: the existing static var generator aging test rack has low strength and poor corrosion resistance, and the length of the test rack cannot be extended, so more items cannot be placed on it, which will affect the storage and organization of the static var generator. Utility Model Content

[0004] The purpose of this utility model is to provide a static var generator (SVM) aging test rack to solve the problems of existing SVM aging test racks, which have low strength, poor corrosion resistance, and cannot be extended in length, thus limiting the storage and organization of SVMs. The preferred technical solutions provided by this utility model and their various technical effects are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a static var generator aging test rack, comprising: a support plate, a connecting plate, and an extension plate. There are two support plates, arranged symmetrically from left to right. There are also two connecting plates, arranged symmetrically from left to right. The extension plate is disposed within the inner cavity of the connecting plate. The outer side of the connecting plate is fixed to the inner side of the support plate. There are five sets of connecting plates, with two plates in each set. The connecting plates are installed at equal intervals from top to bottom on the inner side of the support plate. A long pin is provided on the inner side of the front of each connecting plate, penetrating the inner cavity of the connecting plate and inserting into the front of the extension plate. Each connecting plate includes a steel plate base layer, an alloy steel layer on the outer surface of the steel plate base layer, an electroplated layer on the outer surface of the alloy steel layer, and a sprayed corrosion-resistant paint layer on the outer surface of the electroplated layer.

[0007] Preferably, columns are installed on both the front and rear sides of the bottom of the support plate, and anti-slip pads are installed on the bottom of the columns.

[0008] Preferably, the front side of the extension plate has through holes from left to right for use with the long rod of the pin.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding technical features. The drawings are for illustrative purposes only and are not necessarily drawn to scale.

[0019] See Figure 1 , Figure 2 and Figure 3 As shown in the figure, a static var generator aging test frame includes: a support plate 1, a connecting plate 2, and an extension plate 3. There are two support plates 1, which are arranged symmetrically from left to right. There are also two connecting plates 2, which are arranged symmetrically from left to right. The extension plate 3 is located in the inner cavity of the connecting plate 2. The outer side of the connecting plate 2 is fixed to the inner side of the support plate 1. There are five sets of connecting plates 2, with two in each set. The connecting plates 2 are installed at equal intervals from top to bottom on the inner side of the support plate 1. A pin rod 6 is provided on the inner side of the front of the connecting plate 2. The inner side of the pin rod 6 passes through the inner cavity of the connecting plate 2 and is inserted into the front of the extension plate 3. The connecting plate 2 includes a steel plate base 4. An alloy steel layer 5 is provided on the outer surface of the steel plate base 4. An electroplated layer 7 is provided on the outer surface of the alloy steel layer 5. A corrosion-resistant paint layer 8 is provided on the outer surface of the electroplated layer 7.

[0020] Furthermore, columns 11 are installed on both the front and rear sides of the bottom of the support plate 1, and anti-slip pads 12 are installed on the bottom of the columns 11.

[0021] In this embodiment, the user stores the static var generator that needs to be protected from testing on the connecting plate 2. When it is necessary to extend the length of the connecting plate 2, the user directly pulls the long rod 6 of the pin and then pulls the bracket plates 1 on both sides. The bracket plates 1 drive the connecting plate 2 to move.

[0022] Furthermore, the front side of the extension plate 3 is provided with through holes 9 from left to right for use with the long rod of the pin 6.

[0023] In this embodiment, the connecting plate 2 drives the extension plate 3 to move, and the extension plate 3 drives the guide seat 13 to slide in the inner cavity of the guide rail groove 10, so that the extension plate 3 can move more stably. The extension plate 3 moves completely to one side of the connecting plate 2, which makes it convenient for the user to store the items after it is extended to a suitable length.

[0024] Furthermore, the front side of the connecting plate 2 is provided with through holes from left to right for use with the long rod of the pin.

[0025] In this embodiment, the extension plate 3 and the connecting plate 2 are fixed by the pin rod 6. Alternatively, the extension plate 3 can be retracted into the inner cavity of the connecting plate 2 by the opposite operation described above, and the extension plate 3 can be stored.

[0026] Furthermore, guide rail grooves 10 are provided on the front and rear sides of the inner cavity of the connecting plate 2. Guide seats 13 are slidably connected to the inner cavity of the guide rail grooves 10. The inner side of the guide seats 13 is fixed to the two sides of the front and rear sides of the extension plate 3.

[0027] In this embodiment, the steel plate base layer 4 and the alloy steel layer 5 have excellent properties of withstanding impact, extrusion, and material wear, which increases the strength and wear resistance of the connecting plate 2.

[0028] Furthermore, the connecting plate 2 is made of the same material as the bracket plate 1 and the extension plate 3.

[0029] In this embodiment, the electroplated layer 7 and the sprayed corrosion-resistant paint layer 8 have good adhesion, strong rust prevention, high hardness, and elasticity, which improves the corrosion resistance of the connecting plate 2 and further enhances the strength of the connecting plate 2.

[0030] In use, the user stores the static var generator (SVM) to be tested on the connecting plate 2. When the length of the connecting plate 2 needs to be extended, simply pull the long pin 6, then pull the support plates 1 on both sides. The support plates 1 move the connecting plate 2, which in turn moves the extension plate 3. The extension plate 3 causes the guide seat 13 to slide within the guide rail groove 10, making the movement of the extension plate 3 more stable. The extension plate 3 moves completely to one side of the connecting plate 2, making it convenient for the user to store the equipment and extend it to a suitable length. Then, the extension plate 3 and the connecting plate 2 are fixed by the long pin 6. The extension plate 3 can also be retracted into the inner cavity of the connecting plate 2 by the reverse operation. The steel plate base layer 4 and the alloy steel layer 5 have excellent performance in resisting impact, extrusion and material wear, which increases the strength and wear resistance of the connecting plate 2. The electroplating layer 7 and the sprayed anti-corrosion paint layer 8 have good adhesion, strong rust prevention, high hardness and elasticity, which improves the corrosion resistance of the connecting plate 2 and further improves the strength of the connecting plate 2.
