Description

図1に示す受配電設備は5つの区画に分割されており、それぞれ第1の受電スイッチギヤ8、第2の受電スイッチギヤ9、第1の負荷給電スイッチギヤ10、第2の負荷給電スイッチギヤ11、第1の受電スイッチギヤ8と第1の負荷給電スイッチギヤ10との間に配置したVCT(Voltage and Current Transformer)用スイッチギヤ12に区画され
ている。そして、これらの各スイッチギヤ8、9、10、11、12はそれぞれ独立した筐体に区画されている。また、第1の受電スイッチギヤ8、第2の受電スイッチギヤ9、第1の負荷給電スイッチギヤ10、第2の負荷給電スイッチギヤ11には、それぞれ第1の断路器13、第2の断路器14、第3の断路器15、第4の断路器16が設置されている。なお、これらの各筐体は、通常の配電盤と称される気中絶縁の盤でもよいし、タンク内部に絶縁ガスを封入したガス絶縁形のスイッチギヤでもよい。
1 is divided into five sections, each of which includes a first power receiving switch gear 8, a second power receiving switch gear 9, a first load power switch gear 10, and a second load power switch. A VCT (Voltage and Current Transformer) switch gear 12 is arranged between the gear 11, the first power receiving switch gear 8 and the first load feeding switch gear 10. Each of these switch gears 8, 9, 10, 11, 12 is partitioned into independent housings. Further, the first power receiving switch gear 8, the second power receiving switch gear 9, the first load power feeding switch gear 10, and the second load power feeding switch gear 11 have a first disconnector 13 and a second disconnection, respectively. A device 14, a third disconnector 15, and a fourth disconnector 16 are installed. Each of these cases may be an air-insulated board called a normal switchboard or a gas-insulated switchgear in which an insulating gas is sealed inside the tank.

図2は、実施の形態1による受配電設備であるガス絶縁開閉装置の配置構成を示す図で、図1の回路構成を適用した単線接続図である。
図2に示すように、実施の形態1によるガス絶縁開閉装置は、VCT用スイッチギヤ12に隣接して第1の受電スイッチギヤ8と第1の負荷給電スイッチギヤ10が配置されると共に、第2の受電スイッチギヤ9と第2の負荷給電スイッチギヤ11が互いに隣接して配置されている。
FIG. 2 is a diagram showing an arrangement configuration of a gas insulated switchgear that is a power distribution facility according to the first embodiment, and is a single-line connection diagram to which the circuit configuration of FIG. 1 is applied.
As shown in FIG. 2, a gas insulated switchgear 1 according to the first embodiment, the first power-receiving switch gear 8 and the first load feeder switchgear 10 adjacent the VCT switch gear 12 is disposed, The second power receiving switch gear 9 and the second load feeding switch gear 11 are arranged adjacent to each other.

実施の形態1によるガス絶縁開閉装置1は前記のように構成されており、第2の受電ス
イッチギヤ9、第2の負荷給電スイッチギヤ11を交換する場合には、第1の断路器13、第3の断路器15を開くことで第2の受電スイッチギヤ9、第2の負荷給電スイッチギヤ11は停電状態となり、さらに第2の受電スイッチギヤ9、第2の負荷給電スイッチギヤ11は互いに隣接して配置されているため、第1の受電スイッチギヤ8、第1の負荷給電スイッチギヤ10の運転を停止することなく、安全に交換作業を行なうことができる。
The gas insulated switchgear 1 according to the first embodiment is configured as described above. When the second power receiving switch gear 9 and the second load feeding switch gear 11 are replaced, the first disconnector 13, By opening the third disconnector 15, the second power receiving switch gear 9 and the second load power feeding switch gear 11 are in a power failure state, and the second power receiving switch gear 9 and the second load power feeding switch gear 11 are mutually connected. Since they are arranged adjacent to each other, the replacement work can be performed safely without stopping the operation of the first power receiving switch gear 8 and the first load feeding switch gear 10.

以上のように、実施の形態1による受配電設備1によれば、2つの系統のうち一方の系統のスイッチギヤを交換する場合に、他方の系統の受電及び負荷給電スイッチギヤを分解することなくスイッチギヤの交換が可能となる。なお、実施の形態1の各スイッチギヤは通常の配電盤と称される気中絶縁の盤でもよいし、タンクの内部に絶縁ガスを封入したガス絶縁形のスイッチギヤでもよい。
As described above, according to the power distribution facility 1 according to the first embodiment, when the switch gear of one of the two systems is replaced, the power reception and load feeding switch gear of the other system are not disassembled. The switchgear can be replaced. Each switchgear of the first embodiment may be an air-insulated board called a normal switchboard, or a gas-insulated switchgear in which an insulating gas is sealed inside a tank.

また、図3において、符号19は、第2の受電スイッチギヤ9と第2の負荷給電スイッチギヤ11との相互間を接続する絶縁母線、例えば固体絶縁母線を示し、符号20は、固体絶縁母線19に装着される貫通型変流器を示している。なお、従来においては、第2の受電スイッチギヤ9と第2の負荷給電スイッチギヤ11との相互間の接続は、第2の受電スイッチギヤ9と第2の負荷給電スイッチギヤ11の側部壁面を貫通した水平母線で接続し、これをタンク内において絶縁ガスにて絶縁する構造であるため、変流器を配置する箇所に専用のタンクを配置する必要があった。 In FIG. 3, reference numeral 19 denotes an insulated bus that connects the second power receiving switch gear 9 and the second load feeding switch gear 11, for example, a solid insulated bus, and reference numeral 20 denotes a solid insulated bus. 1 shows a through-type current transformer attached to the body 19. Conventionally, the connection between the second power receiving switch gear 9 and the second load power feeding switch gear 11 is the side wall surface of the second power receiving switch gear 9 and the second load power feeding switch gear 11. connected by a horizontal generatrix passing through the which the order in the tank is a structure that insulated by insulating gas, it is necessary to place the dedicated tank at a location to place the current transformer.
