Specific embodiment
For a better understanding of the present invention, below with reference to the embodiment content that the present invention is furture elucidated, but it is of the invention
Content is not limited solely to the following examples.Those skilled in the art can make various modifications or changes to the present invention, these
Within the scope of equivalent form equally claims listed by the application limit.
As shown in Fig. 1 to 2, the densification tower structure suitable for SVG of the invention, main building block has: cabinet
1, angle 4, SVG module guide rail 5, cabling are moulded in hollow square tube epoxy pulling modeling corner post 2, SVG power module 3, groove profile epoxy pulling
Slot 6.
1 main body frame of cabinet is welded by I-steel and rectangular steel pipe, and top plate 11 and side plate 12 use corrosion-resistant structure
Use hot continuous-milling steel plate；Lining 13 is using with meshed silencing cotton colored steel；Bottom plate is divided into two layers, and upper plate 14 uses rib aluminium
Plate, screw is fixed convenient for wiring disassembly, and lower plate 15 is directly welding as one using the pedestal of cold-rolled steel sheet and cabinet.1 bottom of cabinet
There are specific apertures for portion and top, mould corner post 2 for the epoxy pulling of fixation hollow square tube, hollow square tube epoxy pulling is moulded
2 upper and lower side of corner post is separately connected the bottom and top of cabinet, guarantees hollow square tube epoxy pulling modeling corner post 2 and the bottom of box
Top is completely vertical.As shown in Figs. 3-4.
The cross-brace beam of SVG module guide rail 5 moulds angle 4 using the pulling of groove profile epoxy, by itself and hollow square tube epoxy pulling
It moulds corner post 2 vertically to fix, groove profile epoxy pulling moulds the groove surface at angle 4 outward, and one layer of bottommost is arrived bottom of box metal portion
The distance between part needs to meet the electric clearance and creepage distance of system voltage.The cloth from the bottom up of angle 4 is moulded in groove profile epoxy pulling
Three layers are set, every layer is a phase, is respectively defined as A B C three-phase according to electrical design.Hollow square tube epoxy pulling modeling angle 2 and groove profile
The selection of dimension that angle 4 is moulded in epoxy pulling must the weight according to SVG power module 3 and the stress under transport and seismology
Situation.The cabling channel 6 for placing optical fiber is installed in groove profile epoxy pulling modeling angle 4 and is fastened, both can satisfy SVG power in this way
Stress of the module 3 under various load (transport, earthquake), can also be preferably hidden by cabling channel 6, keeps overall appearance simpler
Clean beauty.All epoxy pulling modeling angle sections only need to carry out the fixed peace that frame can be completed of simple vertical and transverse lap
Dress.As shown in Figs. 3-4.
Conventional SVG equipment uses metallic supports, can increase the spacing between two layers, and is extremely easy under high voltages
Partial discharge phenomenon is generated, service life of equipment is will affect, will cause accident when serious.So moulding angle using groove profile epoxy pulling
The spacing between two layers can be reduced after 4, partial discharge phenomenon will not occur.
It is conventional material that angle is moulded in epoxy pulling, using high-intensitive aramid fiber and glass fibre in epoxy resin-impregnated matrix
Through bonding, molding and hot setting process, pull out the reinforcing profile of continuous length, material have excellent mechanical property,
The features such as electric property, high temperature resistance.Conventional SVG equipment uses metal framework, and manufacturing procedure is cumbersome, and oxidation resistance is poor,
Component is relatively more, and rigging error is caused to increase.And epoxy pulling modeling angle is simple relative to conventional metalwork processing, it is only necessary to
It is simply cut and is punched.Manufacturing cost can significantly be saved.The two kinds of profile section institutes of such as Fig. 5 to 8 used
Show.
Every phase (layer) module is successively attached by SVG power module according to electrical principle by copper bar, is tieing up equipment
It is more clear when shield and maintenance.It is resistance in order to avoid under high voltages since traditional cabinet type SVG has metal framework as support
Pressure and shelf depreciation problem, it is often that the line space design between electrical body and metal framework is very big, so that equipment volume be made to increase
Greatly, but after using epoxy pulling modeling angle section frame, since it is with good insulation performance, device structure can be made more
The compact occupied area to reduce equipment.According to practical engineering calculation, using this densification tower structure layout relative to
The cabinet type mounting means of tradition can save 30% occupied area；Save 20% manufacturing cost.As shown in Figure 9.
