Specific embodiment
The embodiment of Cubicle Gas-Insulated Switchgear：
The structure of Cubicle Gas-Insulated Switchgear is led to as shown in Figure 1, including multiple intervals I between multiple intervals I
It crosses busbar assembly II to be electrically connected to realize each compartment electric current confluence and distribution, busbar assembly II includes A, B, C three-phase bus, single
The concrete structure of phase busbar assembly clamps including disc insulator 1 and by flange as shown in Fig. 2 ~ 5 and is fixed on adjacent two benzvalene form
Housing 2 between insulator, disc insulator 1 be located in housing 2 and including the insulating body 11 made of epoxy resin and by
Center conductor 12 caused by aluminum, electrical connection 3 are secured by bolts on center conductor 12 to realize center conductor 12 with being electrically connected
3 are connect to be conductively connected.
Electrical connection 3 includes the flange 32 of the outer surface of the inserting section 31 of front end and the protrusion inserting section of rear side, flange 32
Outer diameter is more than the outer diameter of inserting section 31, and the blind hole along the axis direction extension of electrical connection 3 is offered on the rear end face of inserting section 31
35, the hole depth of blind hole 35 be more than inserting section 31 length thus its part stretch in the shaft part corresponding to flange 32.Inserting section
The second heat emission hole 33 along the radial direction extension of electrical connection 3 is offered on 31, the second heat emission hole 33 penetrates through the wall of inserting section 31
It is thick.The annular groove 34 that installation is sunk to for 6 part of spring touch finger, annular groove 34 are also machined on the peripheral surface of the inserting section 31 of electrical connection 3
Connected with the second heat emission hole 33 and its groove width be more than the second heat emission hole 33 diameter.Insulation is arranged on the peripheral surface of electrical connection 3
Gasket 5, the rear end face of insulation spacer 5 are mounted on the front end face of flange 32, the front end face of insulation spacer 5 and the conducting rod of tubulose
There is certain gap between 4 rear end face, the position of one of them the second heat emission hole 33 and the position of this gap are adapted.
