<p>PURPOSE:To absorb expansion and compression of a gas-insulated transmission line formed of a long gas-insulated bus due to the atmospheric temperature. CONSTITUTION:One or more bents are provided at a long gas-insulated bus 1, and a piston 13 provided with a passage 18 is coupled to a vessel 3 for constituting the bus 1. The passage 18 is so provided in size as not to respond at the piston 13 to the period of a vibration at the time of an earthquake, and the vessel 3 is operated equivalent to the case so as to be integrally fixed to a base 9. However, if liquid 16 is slowly expanded like a temperature rise, the liquid 16 is moved through a passage 19 provided in a cylinder 11 and the passage 18 provided in the piston 13. Thus, it can cope with the deformation of a transmission line due to a temperature change.</p> |
