Abstract
A novel connecting system for a gas-insulated switchgear apparatus is disclosed. An electrical device is installed on a foundation adjacent to gas-insulated devices of respective phases in a predetermined indoor installation space, and bushing are arranged on the other side of the electrical device. The gas-insulated devices are connected to the bushings by gas-insulated bus bars respectively. Pits for gas-insulated bus bars are formed independently through the foundation of the electrical device, and a transport unit is laid in each of the pits. This transport unit is combined with a transfer unit mounted on each of the gas-insulated bus bars to transport the gas-insulated bus bars of respective phases to facilitate the laying thereof. The gas-insulated bus bars are thus laid in a short distance without reducing the strength of the foundation of the electrical device while at the same time facilitating the laying of the gas-insulated bus bars.
