Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1 and 2, according to an aspect of the present invention, a composite material converter cabinet is provided, comprising a sheet member 100, the sheet member 100 being as shown in fig. 3 and 4, the sheet member 100 comprising a filler material 102 and a composite material portion 101 covering the filler material 102. For example, the composite material portions 101 are provided on the upper and lower surfaces of the filler material 102, respectively, and the filler material 102 can reinforce the strength of the sheet member 100.
It should be noted that the thin plate member 100 of the present invention includes a plate member such as the cabinet main body 1 mentioned below and a beam member such as the electric component mounting beam 7.
Further, the composite material is a glass fiber composite material or a carbon fiber composite material.
Preferably, the density of the carbon fiber composite material is only about 1.8g/cm3Therefore, it has an incomparable advantage in terms of weight reduction. Therefore, the composite material converter cabinet body is a carbon fiber converter cabinet body. Because the converter cabinet body made of the carbon fiber composite material is adopted, under the condition of the same product, the weight of the converter cabinet body can be reduced by more than 25% compared with an aluminum alloy cabinet body, and the weight of the converter cabinet body can be reduced by more than 35% compared with carbon steel and stainless steel cabinet bodies; thereby reach the purpose that promotes cabinet body lightweight level.
Specifically, the composite material portion 101 is a carbon fiber laminate 111 or a glass fiber laminate.
Optionally, the carbon fiber laminate 111 is formed by laying prepreg carbon fiber cloth 112 layer by layer, wherein the number of the prepreg carbon fiber cloth is 4-60 layers.
According to the installation position of the thin plate member 100 and the matching condition with other components, the corresponding stress condition of the thin plate member 100, such as mainly tensile stress or shearing force, can be calculated and obtained. According to different stress conditions of different sheet members 100, the prepreg carbon fiber cloth 112 can be selectively laid in different directions, and different laying angles not only can achieve the purpose of preventing warping, but also can improve the shearing resistance of the sheet members.
The lay-up of the pre-preg carbon fibre cloth 112 may be chosen in a number of ways, for example symmetrical or asymmetrical. Generally, the ply angle of the prepreg carbon fiber cloth 112 is some specific angle, such as 0 °, ± 30 °, ± 45 °, ± 60 ° or 90 °. The laying angle is easy to implement in process and has certain process feasibility.
Preferably, the lay-up angles are different for adjacent prepreg carbon fiber cloth 112.
The following describes a manner of symmetrically laying the prepreg carbon fiber cloth 112.
When the number of the carbon prepreg fibers 112 is a single layer, the carbon prepreg fibers 112 have one intermediate layer, and the lay-up angles of the carbon prepreg fibers 112 above the intermediate layer and the carbon prepreg fibers 112 below the intermediate layer are symmetrical with respect to the intermediate layer. For example, if the number of the prepreg carbon fiber cloth 112 is 7, the 4 th layer is an intermediate layer, and the lay-up angles of the 1 st, 2 nd and 3 th layers are respectively symmetrical with respect to the lay-up angles of the 4 th layer and the 7 th, 6 th and 5 th layers. Assuming that the ply angles of the 1 st, 2 nd and 3 rd plies are 0 °, 30 ° and 60 °, respectively, and the ply angle of the 4 th ply is 90 °, the lay angles of the 5 th, 6 th and 7 th plies are 60 °, 30 ° and 0 °.
In the case where the number of the carbon fiber prepreg sheets 112 is a single layer, it has two intermediate layers, and the lay-up angles of the two intermediate layers may be set to be the same. The lay-up angles of the prepreg carbon fiber cloth 112 above the two intermediate layers and the prepreg carbon fiber cloth 112 below the two intermediate layers are symmetrical with respect to the two intermediate layers. For example, if the number of the prepreg carbon fiber cloth 112 is 8, the 4 th and 5 th layers are intermediate layers, and the lay-up angles of the 1 st, 2 nd and 3 th layers are symmetrical with respect to the lay-up angles of the 4 th and 5 th layers and the 8 th, 7 th and 6 th layers, respectively. Assuming that the ply angles of the 1 st, 2 nd and 3 rd layers are 0 °, 30 ° and 60 °, the ply angle of the 4 th layer is 90 °, and the ply angle of the 5 th layer is 90 °, the lay angles of the 6 th, 7 th and 8 th layers are 60 °, 30 ° and 0 °.
Note that the layer 1 is defined as a layer closest to the filler material 102.
As shown in fig. 5, prepreg carbon fiber cloth layer 111 is formed by stacking 5 layers of prepreg carbon fiber cloth 112, wherein the stacking angles of prepreg carbon fiber cloth 112 are 0 °, 45 °, 90 °, 45 °, and 0 ° from the bottom to the top.
The above-described symmetrical arrangement of the prepreg carbon fiber cloths 112 can prevent the formed carbon fiber laminate 111 from warping and deforming.
For the asymmetric laying of the prepreg carbon fiber cloth 112, different ply angles are adopted for the adjacent prepreg carbon fiber cloth 112. As shown in fig. 4, prepreg carbon fiber cloth layer 111 is formed by stacking 4 layers of prepreg carbon fiber cloth 112, wherein the stacking angles of prepreg carbon fiber cloth 112 are 0 °, 30 °, 60 °, and 90 ° from the bottom to the top, respectively.
It should be noted that the dotted line in fig. 4 and 5 is the main force-receiving direction of the prepreg carbon fiber cloth 112, i.e., the direction of the carbon fiber, and the ply angle is the included angle between the direction of the carbon fiber and the positive direction of the X axis.
In other words, the ply angle of the prepreg carbon fiber cloth 112 in the invention is the included angle between the direction of the carbon fiber in each layer of the prepreg carbon fiber cloth 112 and the positive direction of the X axis.
The rectangular coordinate system of the ply angle is defined as follows: the length direction of the beam member is defined as the X-axis direction, the width direction of the beam member is defined as the Y-axis direction, and the height direction of the beam member is defined as the Z-axis direction.
The prepreg carbon fiber cloth 112 of the present invention is a composite material produced by coating, hot pressing, cooling, coating, and winding a material such as carbon fiber yarn, epoxy resin, and release paper.
Wherein the adopted resin meets the use temperature range of-45 ℃ to 80 ℃; such as an epoxy resin.
Optionally, the carbon fiber laminated plate 111 is formed by laying carbon fiber cloth 113 layer by layer, wherein the number of the carbon fiber cloth 113 is 4-60 layers. In addition, the laying angle of the carbon fiber cloth 113 may be the same as that of the prepreg carbon fiber cloth 112, and will not be described herein.
The difference between the carbon fiber cloth 113 and the prepreg carbon fiber cloth 112 is that the prepreg carbon fiber cloth 112 contains resin, whereas the carbon fiber cloth 113 does not contain resin.
In one embodiment, prepreg carbon fiber cloth 112 is prepreg unidirectional cloth. The prepreg has carbon fibers in only one direction, and since it contains resin itself, the carbon fiber cloth does not scatter. The strength of the whole carbon fiber cloth is concentrated in one direction of the carbon fibers, and the strength of the whole carbon fiber cloth is independent of the gram weight of the whole carbon fiber cloth and only related to the carbon filaments.
In one embodiment, the prepreg carbon fiber cloth 112 is a prepreg bidirectional cloth. The longitudinal and transverse interwoven prepreg bidirectional cloth has a large number of twistless rovings in the longitudinal and transverse directions, and the cloth has two stress directions, and is characterized by multiple interweaving points, firm texture, flat surface, good wear resistance and obviously superior comprehensive stress performance to unidirectional carbon fiber cloth.
Similarly, the carbon fiber cloth 113 includes a non-prepreg unidirectional cloth and a non-prepreg bidirectional cloth, and unlike the prepreg unidirectional cloth, since the non-prepreg unidirectional cloth does not contain resin, there are carbon fibers in one direction, and as shown in fig. 6, there are spun yarns (generally, fine glass fibers) fixed in a direction perpendicular thereto.
The non-prepreg bidirectional cloth is provided with a large number of untwisted rovings in the longitudinal direction and the transverse direction, and the stress directions of the untwisted rovings are the same.
For the prepreg bidirectional cloth and the non-prepreg bidirectional cloth, a traditional weaving plain cloth method is adopted, namely longitudinal carbon fibers and transverse carbon fibers are interwoven in a regular manner from top to bottom. Every other carbon fiber of the longitudinal and transverse carbon fibers is crossed in a cross shape, as shown in fig. 7, the longitudinal carbon fibers are a, b, c and d are arranged above and A, B, C, D is arranged below; the transverse carbon fibers are a, b, c and d above and A, B, C, D below.
Furthermore, the carbon fiber yarns are used for carrying out left-right bidirectional interweaving between the interlayers of the adjacent carbon fiber bidirectional cloth. The interweaving angle of the carbon fiber yarns is 45 degrees, so that the shearing performance can be improved.
The composite material part 101 enables the composite material converter cabinet body to have good effects of rain prevention, dust prevention, temperature insulation, mould prevention, salt fog prevention and damp and heat prevention, and particularly, the composite material converter cabinet body can meet fire risk levels of HL2 and HL3 specified in EN45545-2:2013, is free of electrochemical corrosion and can adapt to the effects of corrosive rain and snow and cleaning agents; and the test requirements of high and low temperature, salt fog and the like specified by IEC 60068-2-1:2007, IEC 60068-2-2:2007, IEC 60068-2-30:2005 and IEC 60068-2-11:1981 are met.

Meanwhile, the carbon fiber composite material is used as a commonly used repairing material, so that the carbon fiber converter cabinet body has excellent repairability. In addition, since the composite material portion 101 has a multi-layer mesh structure, the overall structural safety is not affected even if cracks occur in the limit, thereby improving the structural safety.
