Description

この発明に係るスイッチギヤは、遮断器が収容される遮断器室と、遮断器室の後方にあって母線が収容される母線室と、遮断器室の側方にあって外線ケーブル及びその外線ケーブルと遮断器とを接続する接続導体が収容されるケーブル室とが、仕切板で区画されたスイッチギヤにおいて、遮断器室と母線室との仕切板に、有底筒状の第１の絶縁支持部材が、開口面を遮断器側に向けて設けられ、遮断器室とケーブル室との仕切板に、有底筒状の第２の絶縁支持部材が、開口面を第１の絶縁支持部材の開口面と同方向に向けて設けられ、第１の絶縁支持部材の側面に貫通支持された母線と、遮断器の１次側導体の接触子とが、第１の絶縁支持部材の内部で接続されると共に、第２の絶縁支持部材に挿入支持された接続導体の一端部と、遮断器の２次側導体の接触子とが、第２の絶縁支持部材の内部で接続され、母線と遮断器と接続導体と両絶縁支持部材とで１回路の主回路モジュールが構成されたものである。 Switchgear according to the present invention includes a circuit breaker chamber breakers is accommodated, a bus chamber bus is accommodated In the rear of the circuit breaker chamber, external cables and there on the side of the circuit breaker chamber a cable chamber in which connection conductor for connecting the cross unit shielding the external cable is accommodated in a switch gear are partitioned by a partition plate, the partition plate with the circuit breaker compartment and the bus chamber, a bottomed cylindrical first the insulating support member is provided toward the cross-side shielding the opening surface, the partition plate with the circuit breaker compartment and the cable compartment, a bottomed cylindrical second insulating support member, the opening face first provided toward the same direction as the opening surface of the insulating support member, a busbar which is penetrated supported on the side surface of the first insulating supporting member, and contacts the primary conductor of the breakers is first insulating support is connected inside the member, one end portion of the insertion supporting connection conductor to the second insulating supporting member, breakers of And the contact of the following side conductor, is connected in the second insulating supporting members, the main circuit module 1 circuit in the bus and breakers connecting conductor and the two insulating support members are those composed.

この発明のスイッチギヤによれば、遮断器室と母線室との仕切板に有底筒状の第１の絶縁支持部材を設け、遮断器室とケーブル室との仕切板に有底筒状の第２の絶縁支持部材を設け、第１の絶縁支持部材の内部で母線と遮断器の１次側導体の接触子とを接続すると共に、第２の絶縁支持部材の内部で接続導体の一端部と遮断器の２次側導体の接触子とを接続し、母線と遮断器と接続導体と両絶縁支持部材とで１回路の主回路モジュールを構成したので、母線と遮断器、及び、遮断器とケーブル接続導体の接続経路が簡単になると共に支持部が少なくて済むので支持部品を削減できる。また、一回路あたりの主回路導体長を短くすることができるので、スイッチギヤ全体の縮小化を図ることが可能となる。 According to the switchgear of the present invention, the first insulating support member having a bottomed cylindrical shape is provided on the partition plate between the circuit breaker chamber and the busbar chamber, and the bottomed cylindrical shape is provided on the partition plate between the circuit breaker chamber and the cable chamber. a second insulating support member is provided, along with connecting the contacts of the primary conductor of the cross unit shielding the bus inside the first insulating supporting member, one end of the connection conductor inside the second insulating supporting member parts and barrier connects the contacts of the secondary side conductor cross-sectional unit, since constituting the main circuit module 1 circuit in the bus and breakers and connecting conductor and the two insulating support members, bus and breakers, and, it can be reduced support component so requires less supporting portion together with the connection path of the breakers and the cable connecting conductor is simplified. In addition, since the main circuit conductor length per circuit can be shortened, the entire switch gear can be reduced.

以上のように、実施の形態１によるスイッチギヤによれば、遮断器室と母線室との仕切板に有底筒状の第１の絶縁支持部材を設け、遮断器室とケーブル室との仕切板に有底筒状の第２の絶縁支持部材を設け、第１の絶縁支持部材の内部で母線と遮断器の１次側導体の接触子とを接続すると共に、第２の絶縁支持部材の内部で接続導体の一端部と遮断器の２次側導体の接触子とを接続し、母線と遮断器と接続導体と両絶縁支持部材とで１回路の主回路モジュールを構成したので、母線と遮断器、及び、遮断器とケーブル接続導体の接続経路が簡単になると共に、支持部が少なくて済むので支持部品を削減できる。また、一回路あたりの主回路導体長を短くすることができるので、スイッチギヤ全体の縮小化を図ることが可能となる。 As described above, according to the switchgear according to the first embodiment, the first insulating support member having a bottomed cylindrical shape is provided on the partition plate between the circuit breaker chamber and the busbar chamber, and the partition between the circuit breaker chamber and the cable chamber is provided. the bottomed cylindrical second insulating supporting member provided in the plate, internally as well as connecting the contacts of the primary conductor of the cross unit shielding the generatrix of the first insulating supporting member, a second insulating support member of internally connecting the contacts of the secondary side conductor sectional unit shielding an end portion of the connecting conductor, since constituting the main circuit module 1 circuit in the bus and breakers connecting conductor and the two insulating support members , bus and breakers, and, together with the connection path breakers and the cable connecting conductor is simplified, thereby reducing the support component so requires less support. In addition, since the main circuit conductor length per circuit can be shortened, the entire switch gear can be reduced.
