ガス絶縁開閉装置が建物の地下に設置されるようになっ
た。(Prior Art) Generally, a gas insulated switchgear is configured by connecting gas insulated equipment such as a gas circuit breaker. Due to increased capacity of devices and restrictions on installation locations due to increased demand for electric power, large gas insulated switchgears have come to be installed in the basements of buildings.
また、ガス遮断器は大容量化に伴ない一層の高速動作が
必要となっている。このため、ガス遮断器の動作に際し
、大きな操作振動が発生し、この操作振動が建物に伝達
されることになる。この振動の伝達は近隣機器の誤動作
等の悪影eを発生させる。Furthermore, as gas circuit breakers increase in capacity, they are required to operate at higher speeds. Therefore, when the gas circuit breaker operates, large operational vibrations are generated, and this operational vibration is transmitted to the building. The transmission of this vibration causes adverse effects such as malfunction of neighboring devices.
そこで、ガス遮断器自体の操作振動を低減するか、振動
の伝達経路を制限することが必要となる。Therefore, it is necessary to reduce the operational vibration of the gas circuit breaker itself or to limit the vibration transmission path.
ところが、前者の方法はガス遮断器の遮断性能十現状で
は制約があるため実現できず、専ら後者の方法が採用さ
れている。However, the former method cannot be realized due to current limitations in the breaking performance of the gas circuit breaker, and the latter method is exclusively used.

ース3が複数の弾性支持体4を介して建屋床5トに載置
固定されている。Here, a conventionally used method will be explained using FIG. 3. That is, a gas insulated switchgear 2 including a gas circuit breaker 1 and the like is placed all together on a base 3. Furthermore, this base 3 is mounted and fixed on a building floor 5 via a plurality of elastic supports 4.
このように構成することにより、カス遮断器]て発生す
る操作振動は、数分の−に軽減され建屋床5に伝達され
る。これにより、ガス遮断器]か近接機器等に与える悪
影響は低減される。With this configuration, the operational vibration generated by the cass breaker is reduced to several minutes and transmitted to the building floor 5. As a result, the adverse effects on the gas circuit breaker and adjacent equipment are reduced.
そして、振動理論−1−弾性支持体4の剛性を弱くする
ことで、振動系の固有振動数を下げて振動伝達率を少な
くすることができろ。Vibration Theory - 1 - By weakening the rigidity of the elastic support 4, it is possible to lower the natural frequency of the vibration system and reduce the vibration transmissibility.
しかしながら、この場合カス絶縁開閉装置2の組立にあ
たり、各機器の据伺調整に多くの手間と時間とが必要で
ある。また、カス遮断器」操作時のガス絶縁開閉装置2
の振幅が増加する。さらに、地震時の振動増幅比すなわ
ち応答倍率か増加する。However, in this case, when assembling the cass insulation switchgear 2, much effort and time are required for on-site adjustment of each device. In addition, the gas insulated switchgear 2 when operating the "Cass circuit breaker"
The amplitude of increases. Furthermore, the vibration amplification ratio, that is, the response magnification during an earthquake, increases.
このようなことを考慮して、振動伝達率が決定されるの
で、振動伝達を所定値に低減することが回前(である。Since the vibration transmission rate is determined in consideration of such things, it is necessary to reduce the vibration transmission to a predetermined value.
(発明が解決しようとする課題)
このように、従来のガス絶縁開閉装置は、ベース及び弾
性支持体のみを介して建屋床に載置固定されているので
、振動伝達の低減に限界があった。(Problem to be solved by the invention) As described above, the conventional gas-insulated switchgear is mounted and fixed on the building floor only via the base and elastic support, so there is a limit to the reduction of vibration transmission. .
本発明は上記の点を考慮して成されたもので、振動伝達
低減を図った地下変電所用のガス絶縁開閉装置を提供す
ることを目的とする。The present invention has been made in consideration of the above points, and an object of the present invention is to provide a gas insulated switchgear for underground substations in which vibration transmission is reduced.
