GIS transition bus and GIS

Abstract

The invention relates to a GIS transition bus and a GIS, the transition bus comprises a transition connection shell, a support insulator and a connection conductor, the transition connection shell is used to conveniently realize fixed assembly of a three-phase common box cylinder and a single-phase voltage transformer, the transition connection shell has a smooth reducing section, the radial size of the front end of the transition connection shell is smaller than that of the rear end; and the connection conductor is provided with an inclined extension section, so that a conductive plugging terminal is arranged corresponding to the center of the transition connection shell. According to the transition bus for the GIS, fixed assembly of the three-phase common-box cylinder and the single-phase voltage transformer is conveniently achieved through the transition connection shell, the single-phase voltage transformer and any phase of conductor can be conductively connected through the connecting conductor matched with the conductive insert, electricity taking operation is achieved, and through the inclined extension section on the connection conductor, centering arrangement of the single-phase voltage transformer is convenient to achieve, centering outgoing is convenient, and the overall arrangement coordination of GIS parts is improved.

Description

technical field [0001] The invention belongs to the field of gas insulated switchgear, and in particular relates to a transition bus for GIS and the GIS. Background technique [0002] At present, the isolating switches used by 126kV GIS of domestic and foreign manufacturers are basically three-phase common tanks, and the single-phase PTs and arresters are arranged upwards. The PTs and arresters are generally connected to the isolating switch through a transition welding shell. In practical engineering applications, in order to reduce the overall height of GIS, it is considered to arrange the voltage transformer in the horizontal direction of the disconnector, such as the three-phase common box type gas-insulated metal-enclosed switchgear disclosed in the Chinese utility model patent with the authorized announcement number CN201667503U , which is connected to a voltage transformer at the horizontal side port of the isolating switch through a pot insulator, and the voltage tra...
