Capacitor unit 4-3 generallys use m*n, and (m is the number of plies, and n is every layer capacitor unit number, can be held according to capacitor
Amount requires selection m and n) form is arranged.
Wherein this example uses 2*6 unit arrangement, and capacitor unit uses insulation crust.Capacitor unit layering is put
It sets on all insulation frame 4-1, electrical connection is realized by connecting wire 4-4 between each capacitor unit 4-3, while every layer each
It is separated and positions by cell separators 4-2 between neighboring capacitors unit, and guarantee to stay between neighboring capacitors unit 4-3
There is insulating oil channel, insulating oil circulates in the channel in capacitor operational process, and then plays as capacitor unit 4-3 drop
Temperature effect.Cell separators are stuck on limit plate 4-5 by cutting concave indentation at its both ends, while passing through capacitor unit
Certain expansion occurs after immersion oil to fix.
It is every in all insulation frame 4-1 to guarantee that capacitor unit 4-3 does not fall out all insulation frame 4-1 in transportational process
A limit plate 4-5 is respectively installed in layer two sides, and limit plate and column corresponding position process tapped through hole, by insulated bolt by limit plate
It is fixed on column.
In first embodiment as shown in Figure 3, all insulation frame 4-1 using glass fiber compound material profile layered splicing and
At.Every layer of all insulation frame by after insulation crossbeam 4-1-1 and insulation stringer 4-1-2 splicing by insulation connection sheet 4-1-4 and exhausted
Edge bolt 4-1-5 is attached, then each layer frame and insulation column 4-1-3 are assembled into entire all insulation frame, column and each
Layer frame is also by insulation connection sheet and insulated bolt connection.Each insulation crossbeam, insulation stringer, insulation column, insulation connection
Piece and insulated bolt bonding strength are analyzed by finite element stimulation, and intensity, rigidity meet design and use requirement.
The material of Vierendeel girder (including insulation crossbeam, insulation stringer and the column that insulate) is glass fiber compound material profile,

Assembling.
Specific customization section is not used for conventional rectangular section in the profile that Vierendeel girder uses, and cross sectional shape is simple, general,
Conventional profile pultrude process can be used to be produced.
Frame splicing position is attached using insulation connection sheet 4-1-4, and connection type is two-sided clip type, frame connection
The load at position mainly passes through connection sheet and is shared, mitigate connecting portion bolt it is loaded, it is ensured that frame attaching portion position it is strong
Degree and rigidity.
Insulation connection sheet structure type, the uniform specification of connecting portion of the same race, entire frame is only with a few connection
Piece simplifies convenient for number of molds when insulation connection sheet production, reduces production cost.
Since in capacitor long-time use process, insulating oil constantly can slowly generate impurity under high temperature high voltage.With
Increasing for deposit, impurity can release insulating oil and be deposited on 1 bottom of fuel tank, if capacitor core body 4 is directly placed at fuel tank 1
On bottom plate, impurity can have an adverse effect to capacitor electric property.For the shadow to capacitor core body for solving insulating oil impurity
It rings, increases by one group of insulated leg 4-1-6 in the capacitor all insulation bottom frame 4-1.
The cell separators 4-2, limit plate 4-5, insulation connection sheet 4-1-4, insulated bolt 4-1-5 and insulated leg 4-1-
6 materials are all glass fiber compound material with all insulation Vierendeel girder, guarantee that the material meets related want to the compatibility of insulating oil
It asks.
