Description

本発明は、ガス絶縁開閉装置（ＧＩＳ）を設置した屋内又は地下変電所等の変電設備に係り、特にこのガス絶縁開閉装置に電力ケーブルを接続するケーブル室の階高を低くすることができるガス絶縁開閉装置への電力ケーブル接続構造に関するものである。   The present invention relates to a substation facility such as an indoor or underground substation where a gas insulated switchgear (GIS) is installed, and in particular, a gas capable of lowering the floor height of a cable room connecting a power cable to the gas insulated switchgear. The present invention relates to a structure for connecting a power cable to an insulated switchgear.

ガス絶縁開閉装置は、遮断器、断路器、避雷器、母線など開閉装置の充電部を接地金属容器内に配置し、エポキシ樹脂注型品により絶縁支持すると共に、充電部と、接地金属容器との間を絶縁特性の優れたＳＦ６ガスなどを封入した構造の開閉装置である。例えば、屋内又は地下変電所に設置するガス絶縁開閉装置に電力ケーブルを接続するときは、図３に示すように、地下４階に変圧器５１を設置した変圧器室５２を設け、この変圧器室５２の上階層の地下３階に電力ケーブル５３を引き出すケーブル室５４を設け、このケーブル室５４の上階層の地下２階にガス絶縁開閉装置５５を設置した開閉器室５６を設けた地下変電設備において、ガス絶縁開閉装置５５に電力ケーブル５３を接続していた。 In the gas insulated switchgear, the charging part of the switchgear such as a circuit breaker, disconnector, lightning arrester, bus, etc. is placed in a grounded metal container, insulated and supported by an epoxy resin casting product, and between the charging part and the grounded metal container This is a switchgear having a structure in which SF 6 gas or the like having an excellent insulating property is sealed. For example, when connecting a power cable to a gas-insulated switchgear installed in an indoor or underground substation, as shown in FIG. 3, a transformer room 52 having a transformer 51 is provided on the fourth basement floor. A cable room 54 for drawing out the power cable 53 is provided on the third basement floor above the room 52, and a switch room 56 provided with a gas insulated switchgear 55 on the second basement floor above the cable room 54 is provided. In the facility, the power cable 53 is connected to the gas insulated switchgear 55.

一般に、ケーブル室５４において、電力ケーブル５３は、この電力ケーブル５３の許容曲げ半径以内で電力ケーブル５３を湾曲させてガス絶縁開閉装置５５に接続していた。そして、このガス絶縁開閉装置５５から接続母管５７を介して下層階の変圧器室５２の変圧器５１と接続していた。   Generally, in the cable chamber 54, the power cable 53 is connected to the gas insulated switchgear 55 by bending the power cable 53 within an allowable bending radius of the power cable 53. The gas-insulated switchgear 55 is connected to the transformer 51 in the transformer room 52 on the lower floor via the connection mother pipe 57.

ガス絶縁開閉装置に関する先行技術としては、特許文献１の実開平６−７４０１０号公報の「ガス絶縁開閉装置」がある。この「ガス絶縁開閉装置」では、図４に示すように、母線部分、遮断器部分および線路側機器部分を有し、線路側機器部分の電力ケーブル端末ブロックに電力ケーブルが直接接続されるガス絶縁開閉装置において、電力ケーブル端末ブロックの中心軸を、垂直軸に対して任意の角度だけ傾けた状態で設けることにより、電力ケーブル６１をガス絶縁開閉装置６２から斜め下方に引き出すようにした、構造のものが提案されている。このように従来では電力ケーブル６１をガス絶縁開閉装置６２から斜め下方に引き出すことにより、地下室が省略できるようになっている。
実開平６−７４０１０号 As a prior art relating to a gas insulated switchgear, there is "Gas insulated switchgear" disclosed in Japanese Utility Model Publication No. 6-74010. In this “gas insulated switchgear”, as shown in FIG. 4, a gas insulation having a bus part, a circuit breaker part, and a line side device part, in which a power cable is directly connected to a power cable terminal block of the line side device part. In the switchgear, the central axis of the power cable terminal block is provided in an inclined state with respect to the vertical axis so that the power cable 61 is drawn obliquely downward from the gas insulated switchgear 62. Things have been proposed. Thus, conventionally, the basement can be omitted by pulling the power cable 61 obliquely downward from the gas insulated switchgear 62.
Utility Kaihei 6-74010

また、地下室を省略するために、この特許文献１には、従来技術を表す記載として、「この第２の例においては、ケーブルヘッド容器内の下部において水平に取り付けられる。また、架台内の変流器も、ケーブルヘッドと同一高さで水平方向に取り付けられる。そして電力ケーブルは、ケーブルヘッド、変流器を通して水平方向に引き出され、処理部において曲げられてその高さ位置を変え、ＧＩＳフロアー上に敷設される。」構造のものが提案されている。   In addition, in order to omit the basement, this Patent Document 1 describes, as a description representing the prior art, “In this second example, it is attached horizontally at the lower part in the cable head container. The flutes are also mounted horizontally at the same height as the cable heads, and the power cables are pulled out horizontally through the cable heads and current transformers, bent at the processing section to change their height positions, and the GIS floor It is laid on top. "A structure is proposed.

しかし、電力ケーブルは、直角に曲げることができないため、接続する電力ケーブルの径のサイズが太くなればなるほど曲げ半径が長くなり、この電力ケーブルを湾曲させるための空間が必要になり、ケーブル室の階高が高くなり、地下建物の建設工事費が高額になっていた。   However, since the power cable cannot be bent at a right angle, the larger the diameter of the power cable to be connected, the longer the bending radius becomes, and a space for bending the power cable is required. The floor height was high and the construction cost of the underground building was high.

また、特許文献１に記載されている技術は、単純に電力ケーブルを処理するための地下室を省略することにより、建設工事費を低減しているだけである。複数本の電力ケーブルを引き出す必要がある屋内の変電所又は地下変電所には不向きなものであった。特に、ガス絶縁開閉装置の設置方向により、これに接続する電力ケーブルの引き出し方向が決められるので、電力ケーブルの引き込み方向性が特定されるという問題を有していた   Moreover, the technique described in patent document 1 is only reducing the construction construction cost by omitting the basement for processing an electric power cable. It was unsuitable for indoor substations or underground substations where it was necessary to draw out multiple power cables. In particular, since the direction of drawing out the power cable connected to the gas insulated switchgear is determined by the installation direction of the gas insulated switchgear, there is a problem that the direction of drawing in the power cable is specified.

更に、特許文献１に記載されているように、ガス絶縁開閉装置から電力ケーブルを斜め下方に引き出す構造のものでは、このガス絶縁開閉装置の周囲に電力ケーブルが引き出されるために、ガス絶縁開閉装置の保守・点検の際に、これらの電力ケーブルが作業上の邪魔になり、開閉器室の作業性が低下するという問題を有していた。   Further, as described in Patent Document 1, in the structure in which the power cable is drawn obliquely downward from the gas insulated switchgear, the power cable is pulled out around the gas insulated switchgear. During the maintenance and inspection of these, these power cables obstruct work, and there is a problem that workability of the switch room decreases.

本発明は、かかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、ケーブル室にガス絶縁母管接続部を設けることで、電力ケーブルを湾曲させるための空間を不要にしてケーブル室の階高を低くすると共に、このケーブル室において複数本の電力ケーブルは這わせることを可能にし、かつ電力ケーブルの引き込みの方向性の自由度を高め、また、ガス絶縁開閉装置の開閉器室の作業性を高めることができるガス絶縁開閉装置への電力ケーブル接続構造を提供することにある。   The present invention has been developed to solve such problems. That is, an object of the present invention is to provide a gas insulation mother pipe connection portion in a cable room, thereby eliminating the space for bending the power cable and lowering the floor height of the cable room. The power cable to the gas-insulated switchgear can be made to be twisted, and the degree of freedom in the direction of drawing in the power cable can be increased, and the workability of the switch-insulated room of the gas-insulated switchgear can be improved. It is to provide a cable connection structure.

本発明によれば、変圧器室（１）と、該変圧器室（１）と別の階層に設けた開閉器室（３）と、前記変圧器室（１）と開閉器室（３）との間の階層に設けたケーブル室（２）と、から成る屋内又は地下変電所等に用いられる変電設備に電力ケーブル（９）とを接続する電力ケーブル接続構造であって、前記ケーブル室（２）に、その階高が低くなるように、前記開閉器室（３）に設置したガス絶縁開閉装置（５）から略垂直にガス絶縁母管（７）を引き出し、該ガス絶縁母管（７）の軸方向に対して略直交するようにケーブルヘッド（８）を接続して成るガス絶縁母管接続部（６）を配置し、前記ガス絶縁母管接続部（６）のケーブルヘッド（８）に、電力ケーブル（９）を接続した、ことを特徴とするガス絶縁開閉装置への電力ケーブル接続構造が提供される。   According to the present invention, the transformer room (1), the switch room (3) provided on a different level from the transformer room (1), the transformer room (1) and the switch room (3) A power cable connection structure for connecting a power cable (9) to a substation facility used in an indoor or underground substation, etc. 2), the gas insulation mother pipe (7) is pulled out almost vertically from the gas insulated switchgear (5) installed in the switch room (3) so that the floor height is lowered, and the gas insulation mother pipe ( 7) A gas insulated mother pipe connecting portion (6) formed by connecting the cable head (8) so as to be substantially orthogonal to the axial direction of 7) is arranged, and the cable head ( 8) is connected to a power cable (9), and is connected to a gas insulated switchgear. Structure is provided.

前記ガス絶縁母管接続部（６）は、前記ケーブル室（２）における前記ガス絶縁開閉装置（５）から垂直に引き出したガス絶縁母管（７）に、該ガス絶縁母管（７）の軸方向に対して周囲方向へその向きを変位可能にケーブルヘッド（８）を接続したものである。   The gas insulation mother pipe connection portion (6) is connected to the gas insulation mother pipe (7) drawn vertically from the gas insulation switchgear (5) in the cable chamber (2). The cable head (8) is connected so that its direction can be displaced in the circumferential direction with respect to the axial direction.

前記ケーブル室（２）の下階層に変圧器室（１）を、該ケーブル室（２）の上階層に開閉器室（３）をそれぞれ設ける。   A transformer room (1) is provided in the lower level of the cable room (2), and a switch room (3) is provided in the upper level of the cable room (2).

上記構成の発明では、電力ケーブル（９）は、ガス絶縁開閉装置（５）から垂直に引き出したガス絶縁母管（７）の軸方向に対して周囲方向へその向きを自由に変えられるケーブルヘッド（８）に接続してあるので、この電力ケーブル（９）はケーブル室（２）において水平方向かつ所望の向きに引き出される。このように電力ケーブル（９）は、ガス絶縁母管接続部（６）を介在して水平に接続できるために、電力ケーブル（９）の径のサイズに左右されずに、ケーブル室（２）の階高を低くすることができ、屋内又は地下変電所の建設工事費を低減できる。   In the invention with the above-described configuration, the power cable (9) is a cable head that can freely change its direction in the circumferential direction with respect to the axial direction of the gas insulated mother pipe (7) drawn vertically from the gas insulated switchgear (5). Since it is connected to (8), this power cable (9) is drawn out in the cable chamber (2) in a horizontal direction and in a desired direction. Thus, since the power cable (9) can be connected horizontally via the gas-insulated mother pipe connection part (6), the cable chamber (2) is not affected by the size of the diameter of the power cable (9). The floor height can be lowered, and the construction cost of the indoor or underground substation can be reduced.

ケーブル室（２）において、多数本の電力ケーブル（９）を這わせることにより、ガス絶縁開閉装置（５）を設置した開閉器室（３）においては、複数の電力ケーブル（９）を引き出していないので、この開閉器室（３）での作業性を高めることができる。また、ガス絶縁母管接続部（６）を介在させることにより、ケーブル室（２）における、電力ケーブル（９）の引き出しの方向性の自由度を高めることができるので、あらゆる方向へ電力ケーブル（９）を引き出すことができる。   In the cable room (2), a large number of power cables (9) are arranged so that a plurality of power cables (9) are drawn out in the switch room (3) where the gas insulated switchgear (5) is installed. Since there is no, workability | operativity in this switch room (3) can be improved. Further, by interposing the gas-insulated mother pipe connection portion (6), the degree of freedom in the direction of drawing out the power cable (9) in the cable chamber (2) can be increased, so that the power cable ( 9) can be pulled out.

本発明は、屋内又は地下変電所に変圧器室と、この変圧器室と別の階層に開閉器室とを設け、これらの変圧器室と開閉器室との間の階層にケーブル室を設けたものである。このケーブル室において、ガス絶縁開閉装置から略垂直にガス絶縁母管を引き出し、ガス絶縁母管の軸方向に対して略直交するようにケーブルヘッドを接続して成るガス絶縁母管接続部に、電力ケーブルを接続することにより、ケーブル室の階高を低くしたものである。   The present invention provides a transformer room in an indoor or underground substation, a switch room at a level different from the transformer room, and a cable room at a level between the transformer room and the switch room. It is a thing. In this cable room, the gas insulation bus pipe is connected to the gas insulation bus pipe connecting portion so that the gas insulation bus pipe is pulled out substantially vertically from the gas insulated switchgear and the cable head is connected substantially perpendicular to the axial direction of the gas insulation bus pipe. By connecting the power cable, the floor height of the cable room is lowered.

以下、本発明の好ましい実施の形態を図面を参照して説明する。
図１は本発明のガス絶縁開閉装置への電力ケーブル接続構造を示す斜視図である。
本発明のガス絶縁開閉装置への電力ケーブル接続構造は、変電所、特に屋内の変電所又は地下変電所に用いる。例えば地下変電所は、地下４階に変圧器室１を設け、この変圧器室１の上階層の地下３階にケーブル室２を設け、更にこのケーブル室２の上階層の地下２階に開閉器室３を設けたものである。この変圧器室１には、変圧器４を設置し、開閉器室３には、ガス絶縁開閉装置５を設置した構成のものである。このガス絶縁開閉装置５は、上述したように遮断器、断路器、避雷器、母線など開閉装置の充電部を接地金属容器内に配置し、エポキシ樹脂注型品により絶縁支持すると共に、充電部と、接地金属容器との間を絶縁特性の優れたＳＦ６ガスなどを封入した構造の開閉装置である。
図示例では、ケーブル室２を挟んで、その下階層に変圧器室１を、上階層に開閉器室３を配置した例を示しているが、逆に下階層に開閉器室３を、上階層に変圧器室１を配置することも可能である。また、変圧器室１から開閉器室３についても、地下４階から地下２階に限定されないことは勿論である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a power cable connection structure to a gas insulated switchgear according to the present invention.
The power cable connection structure to the gas insulated switchgear according to the present invention is used for substations, particularly indoor substations or underground substations. For example, an underground substation has a transformer room 1 on the fourth floor, a cable room 2 on the third basement floor above the transformer room 1, and a cable room 2 on the second basement floor in the upper floor. A chamber 3 is provided. The transformer room 1 is provided with a transformer 4, and the switch room 3 is provided with a gas insulated switchgear 5. As described above, the gas insulated switchgear 5 has a charging part of a switchgear such as a circuit breaker, a disconnector, a lightning arrester, a busbar, etc. disposed in a grounded metal container and insulated and supported by an epoxy resin casting product. The switchgear having a structure in which SF 6 gas having excellent insulating properties is sealed between the ground metal container and the like.
In the illustrated example, the transformer room 1 is arranged in the lower layer and the switcher room 3 is arranged in the upper layer with the cable room 2 interposed therebetween, but conversely, the switcher room 3 is arranged in the lower layer. It is also possible to arrange the transformer room 1 in a hierarchy. Of course, the transformer room 1 to the switch room 3 are not limited to the fourth basement to the second basement.

図２はガス絶縁母管接続部の拡大側面図である。
本発明ではケーブル室２において、ガス絶縁母管接続部６を設けることにより、このケーブル室２の階高が低くなるようにした。このガス絶縁母管接続部６は、ガス絶縁開閉装置５から略垂直にガス絶縁母管７を引き出し、このガス絶縁母管７の軸方向に対して略直交するようにケーブルヘッド８を接続して成るものである。このガス絶縁母管接続部６のケーブルヘッド８に電力ケーブル９を接続したものである。変圧器室１からケーブル室２を経て開閉器室３まで貫通しているものは、Ｔｒ一次接続母管１０である。 FIG. 2 is an enlarged side view of the gas-insulated mother pipe connecting portion.
In the present invention, by providing the gas insulation mother pipe connection portion 6 in the cable chamber 2, the floor height of the cable chamber 2 is lowered. The gas insulated bus pipe connecting portion 6 draws the gas insulated bus pipe 7 from the gas insulated switchgear 5 substantially vertically, and connects the cable head 8 so as to be substantially orthogonal to the axial direction of the gas insulated bus pipe 7. It is made up of. A power cable 9 is connected to the cable head 8 of the gas-insulated mother pipe connection portion 6. What penetrates from the transformer room 1 through the cable room 2 to the switch room 3 is a Tr primary connection pipe 10.

このように電力ケーブル９は、ケーブル室２において、ガス絶縁母管接続部６を介在して水平に接続することにより、電力ケーブル９の径のサイズに左右されないので、従来のように電力ケーブル９を湾曲させるための空間が不要になり、ケーブル室２の階高を低くすることができる。また、多数の電力ケーブル９は、ケーブル室２において這わせることにより、ガス絶縁開閉装置５を設置した開閉器室３においては、多数の電力ケーブル９を引き出していない。即ち、ガス絶縁開閉装置５の周囲に多数の電力ケーブル９が引き出されないので、この開閉器室３おけるガス絶縁開閉装置５の保守、点検等の作業性を高めることができる。   Thus, since the power cable 9 is connected horizontally in the cable chamber 2 with the gas insulation mother pipe connection portion 6 interposed therebetween, the power cable 9 is not affected by the size of the diameter of the power cable 9. A space for curving the cable becomes unnecessary, and the floor height of the cable chamber 2 can be lowered. In addition, since a large number of power cables 9 are arranged in the cable chamber 2, the large number of power cables 9 are not drawn out in the switch chamber 3 in which the gas insulated switchgear 5 is installed. That is, since a large number of power cables 9 are not drawn around the gas insulated switchgear 5, workability such as maintenance and inspection of the gas insulated switchgear 5 in the switch chamber 3 can be improved.

ガス絶縁母管接続部６は、ケーブル室２におけるガス絶縁開閉装置５から垂直に引き出したガス絶縁母管７に、ガス絶縁母管７の軸方向に対して周囲方向へその向きを変位可能にケーブルヘッド８を接続することにより、ケーブル室２における、電力ケーブル９の引き出しの方向性の自由度を高めることができる。   The gas-insulated mother pipe connecting portion 6 can be displaced in the circumferential direction relative to the axial direction of the gas-insulated mother pipe 7 to the gas-insulated mother pipe 7 drawn vertically from the gas-insulated switchgear 5 in the cable chamber 2. By connecting the cable head 8, the degree of freedom in the direction of drawing out the power cable 9 in the cable chamber 2 can be increased.

なお、本発明は、複数階層構成の屋内又は地下変電所におけるケーブル室２において、電力ケーブル９を水平方向に引き出す構造であれば、上述したガス絶縁母管７とケーブルヘッド８とから成るガス絶縁母管接続部６の形態に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。   In the cable room 2 in the multi-tiered indoor or underground substation, the present invention is a gas insulation composed of the gas insulation mother pipe 7 and the cable head 8 as long as the power cable 9 is pulled out in the horizontal direction. Needless to say, the present invention is not limited to the form of the mother pipe connecting portion 6 and can be variously changed without departing from the gist of the present invention.

本発明のガス絶縁開閉装置への電力ケーブル接続構造は、文字通りガス絶縁開閉装置について利用することができるが、電力ケーブルを引き出す構造の電力流通設備であれば、ガス絶縁開閉装置以外の設備にも利用することができる。   The power cable connection structure to the gas-insulated switchgear according to the present invention can literally be used for a gas-insulated switchgear. Can be used.
