Slot group minimum range >=10mm, metric space between the two are all filled with composite material.
It is set to the inside mounting base inserts 4(i.e. module mounting base inserts of 2 inside top surface of lower cabinet body), using stainless steel
Material is used for fixing internal high-pressure modular;It does not need to carry out special preservative treatment, design has screw thread on internal mounting base inserts 4
Hole, for the bolt fastening of high-pressure modular, the connection of internal mounting base inserts 4 and lower cabinet body 2 is using Preembedded or splicing
Mode, to guarantee cabinet body high-voltage isulation performance, between 2 bottom foam sandwich of layers 9 of internal 4 bottom of mounting base inserts and lower cabinet body
Spacing >=10mm, metric space between the two are all filled with composite material.
It is set to the high tension terminal 5 of 2 leading flank of lower cabinet body, using stainless steel material, does not need to carry out special anti-corrosion
By the way of Preembedded or splicing, exposed parts design has along cabinet body for the connection of processing, high tension terminal 5 and lower cabinet body 2
The threaded hole of length direction, the convenient connection cables in narrow space, reduces the installation difficulty of cabinet body component.
It is set to the pull handle arrangement 7 of 2 outside left side of lower cabinet body, using composite material, and lower cabinet body 2 is integrally formed or glue
It connects in succession, it, can be by cabinet body (including upper cover plate and lower cabinet by pull handle arrangement 7 by the way that lower cabinet body bottom to be fixed on guide rail
Body) it is pulled out from narrow space, realize the purpose of maintenance or the replacement of interior of the cabinet high-pressure modular.
Cooling medium pipeline manhole appendix 11, the insulating gas medium for being set to 2 end face of lower cabinet body fill gas vent 12, signal wire
Beam mounting hole 13 meets heat management, built-in electrical insulation adjustment of gas concentration and monitoring, signal transmission of interior of the cabinet high-pressure modular etc.
Functional requirement.
It is arranged fluted on 2 top flange face of lower cabinet body, for placing sealing strip, is fastened by bolts pressure with upper cover plate 1
Tightly seal sealing.
Lower cabinet body side and upper cover plate part (the lower position of insulating requirements) are all made of composite layer+foam sandwich layer
The sandwich structure of+composite layer;It is preferred that are as follows: 2 side of lower cabinet body and 1 part of upper cover plate are all made of 2.5mm thickness composite material
The sandwich structure of layer+5mm thickness foam sandwich layer+2.5mm thickness composite layer, all composite materials of rest part.Lower cabinet
Body bottom uses composite layer+foam sandwich layer+composite layer sandwich structure, the composite wood of lower cabinet body inner bottom surface
Thickness of feed layer is 10mm, and the composite layer thickness of bottom surface is 5 ~ 10mm outside lower cabinet body;It is preferred that are as follows: 2 bottom of lower cabinet body is by interior
To the outer sandwich structure using 10mm thickness composite layer+60mm thickness foam sandwich layer+5mm thickness composite layer.Pass through examination
Verifying, which shows that two layers of composite Materials Design can solve, leads to bottom there are charge concentration due to lower cabinet body internal high pressure module
Portion leads to the problem of flashover to external component.Composite material is fiber-reinforced resin matrix compound material, and fiber selects insulation performance
One or more of excellent glass fibre and basalt fibre;Resin is high insulated type epoxy resin;Foam be PET,
One or more of PMI, PEI;The insulation that can achieve 8.5 ten thousand volts of pressure maintaining 1min using the cabinet body that this structure designs is resistance to
Grade is pressed, the sealing performance requirement in vehicle operational shock vibration processes can also be met, and high-pressure modular system is greatly reduced
The overall volume of system.
The present invention can not only meet high-voltage isulation, the impact vibration of railway vehicle device and bearing requirements, also have light
The characteristics of quantization and miniaturization;The present invention on the basis of existing technology, equally uses sandwich structure, but for inside this
The problem of insulative air gap and creepage distance deficiency proposes new Structural Design Solution, can satisfy 8.5 Wan Fubao
Press the resistance to pressure request of insulation of 1min.
For those skilled in the art, without departing from the principle of the present invention, can also make
Some improvements and modifications out, such as the layout for changing each face of cabinet body, the mounting means for changing internal module, increase creepage distance
" returning " font is changed to annular or other shapes, the quantity for increasing raised annular etc., these improvement and modification also should be regarded as the present invention
Protection scope.
