Embodiment 1

[0056] Such as figure 1 As shown, the GIS provided by this embodiment includes a circuit breaker, an isolating switch 1 and a busbar connection device, wherein the isolating switch includes a tank body 11, and three phases are arranged on the tank body 11, and the GIS busbar connection device is connected to the three phases, and the busbar passes through the GIS The bus connection device is connected with the three phases on the tank body 11 .

[0057] In this embodiment, the GIS bus bar connecting device includes three joints, each of which is connected to one bus bar, and these three joints are respectively the first joint 2 , the second joint 3 and the third joint 4 . The three phases on the tank are arranged in a straight line, and the direction of the three phases is consistent with the extension direction of the main busbar. The direction of the three phases is set to be the front and rear direction. The phase is the side phase. The first joint 2 is connected to the m...

Embodiment 2

[0067] The difference between this embodiment and Embodiment 1 lies in that in Embodiment 1, the structures of the second joint and the third joint are the same. However, in this embodiment, the structures of the second joint and the third joint are different, and the specific difference lies in the different sizes of the second joint and the third joint. In other embodiments, the second conductor in the second joint is a split structure with two sections connected, or the second conductor in the second joint is in an integral structure.

Embodiment 3

[0069] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the first joint is arranged on the middle phase of the three phases, the second joint is arranged on a phase in front of the middle phase, and the third joint is arranged on On a phase behind the intermediate phase. In this embodiment, however, the second joint is arranged on the middle phase of the three phases, the third joint is arranged on a phase on the front side of the middle phase, and the first joint is arranged on a phase on the back side of the middle phase. In other embodiments, the third connection is arranged on an intermediate phase among the three phases, the first connection is arranged on a phase on the front side of the intermediate phase, and the second connection is arranged on a phase on the rear side of the intermediate phase.

Description

technical field [0001] The invention relates to the technical field of GIS, in particular to a GIS bus connection device and a GIS. Background technique [0002] At present, the busbars in GIS with a voltage level below 252KV are usually arranged in a common box. The isolating switch in the GIS is arranged in a line with three phases and is consistent with the extension direction of the main busbar. The common box bus is connected through the common box busbar. Connect to three phases on the disconnect switch. The existing common-box busbar connection structure usually adopts the structure provided by the patent specification whose authorized announcement number is CN202172242U. The common-box busbar connection structure includes a shell, a T-shaped conductor and two L-shaped conductors. Three The pot insulators arranged in a line, the T-shaped conductor is fixed on the middle pot insulator, and the two L-shaped conductors are respectively fixed on the pot insulators on bot...
