Description
【発明の詳細な説明】 この発明はガス絶縁開閉装置に関するもので。[Detailed description of the invention] This invention relates to gas insulated switchgear.
特にガス絶縁開閉装置の基礎上に長く布設される電力用
ガス絶縁母線の支持構造に関するものである。In particular, the present invention relates to a support structure for a long gas-insulated power bus bar installed on the foundation of a gas-insulated switchgear.
一般K、ガス絶縁母線はガス絶縁開閉装置において、主
として、しゃ断部を収納したしゃ断ユニットや断路部を
収納した断路ユニット等の各機能要素を結合させるため
に用いられることが多い。Generally speaking, gas insulated busbars are often used in gas insulated switchgear primarily to connect functional elements such as a breaker unit housing a breaker and a disconnection unit housing a disconnector.
その中で、送電線ユニットや変圧器ユニット等として各
々一群となっている開閉装置群の全てに亘って連絡する
いわゆる主母線は必然的に長尺となるものである。Among these, the so-called main bus bar, which connects all of the switchgear groups, each of which is a power transmission line unit, transformer unit, etc., is inevitably long.
基礎上に布設されたこのような主母線は通電や環境の影

縮量は基礎のそれより大きい。このため長い主母線両端
附近では、基礎忙設置された機器が、主母線の熱伸縮に
より強制的に変形されるという機械的な悪影響を受け、
これは主母線が長尺化されればされる程著しくなる。The temperature of such a main busbar installed on the foundation changes due to the influence of electricity and the environment. Similarly, temperature changes occur in the foundation itself, but gas-insulated busbars generally expand thermally due to the heat generated when electricity is applied and the effects of direct sunlight, and due to the difference in expansion coefficients, the amount of expansion and contraction due to heat is greater than that of the foundation. For this reason, near both ends of the long main bus bar, equipment installed on the foundation is subject to negative mechanical effects as it is forcibly deformed due to thermal expansion and contraction of the main bus bar.
This becomes more noticeable as the main bus line becomes longer.

するものである。Conventionally, there have been the following five structural examples as measures to solve this problem. Figures 1 and 2 show an example of the configuration of a conventional gas-insulated switchgear, in which a breaker l installed on the foundation is connected to a line input/output cable head via a current transformer and a joint busbar 3. This circuit is connected to the main bus line AK current transformer/coco disconnector S. In such a switchgear group, the main busbar is supported by supporting the main busbar, which is divided into each unit, from below using a fixed base lθ, as shown in Fig. 2. The installation is fixed at the location where it will be installed. The main busbars 6 are connected by an expansion joint 7 such as a bellows, and the end t of the tie rod g is movable in order to escape thermal expansion and contraction. As shown in Figure 3, the details of the movable structure are as follows: K, tie rod tK screwed double nut/4
Both the 7 flange portions 1 and 16 of the generatrix A are provided with a gap B to be free from thermal expansion and contraction.

、大がかりな補強装置13を必要とする欠点があった。In the conventional configuration as described above, one drawback is the cantilevered structure of the fixing base io shown in FIG. That is,
The body plate of the busbar O, which is a pressure vessel that receives gas pressure F reaching several 10 tons, is bolted to the base base with IC bolts/2 via the fixing base IO, which requires a large-scale installation. There was a drawback that a reinforcement device 13 was required.

A strong fixed stand is provided near both ends, the flanges or end plates of the metal container at both ends are joined to the foundation base buried underground, and the axial reaction force due to the pressure of the sealed gas is supported by the fixed stand. The company provides gas-insulated switchgear featuring the following characteristics.
