Embodiment Construction

[0041] see figure 1 with Figure 1a , for the single busbar structure, a set of vertically telescopic 0° isolating switch 2 is adopted, and the three-phase moving contacts in the vertically telescoping 0° isolating switch 2 are arranged along a direction parallel to the tubular busbar 4 .

[0042] An insulating rod 1 is set above the movable contact of the vertical telescopic 0° isolating switch 2 along the direction parallel to the tubular bus 4 at a set height, and the three-phase static in the vertically telescopic 0° isolating switch 2 The contacts 3 are distributed on the insulating rod 1 at a set interval, and the tubular busbars 4 of each phase fixed on the tubular busbar frame are connected to the static contacts 3 of the corresponding phases in the vertical telescopic 0° isolating switch through the down conductor 15 connect.

[0043] Such as figure 1 As shown, a suspension beam 6 is arranged at the bottom of the tubular busbar frame, and the insulating rod 1 is ...

Abstract

The invention discloses a disconnecting switch arrangement structure for a transformer substation power distribution unit. The disconnecting switch arrangement structure is characterized in that a vertical telescopic 0-degree disconnecting switch is adopted, and each movable contact in the 0-degree disconnecting switch is arranged along a direction parallel to a tubular bus bar; an insulating bar is arranged above the movable contacts of the 0-degree disconnecting switch along the direction parallel to the tubular bus bar according to a set height; each static contact in the 0-degree disconnecting switch is distributed on the insulating bar at set intervals; each tubular bus bar fixedly arranged on a tubular bus bar framework is connected with each corresponding static contact in the 0-degree disconnecting switch through leads. By adopting the disconnecting switch arrangement structure, the longitudinal size of a power distribution unit area can be reduced effectively, the floor area of a transformer substation is reduced, and the application range of an AIS (Automatic Identification System) power distribution unit is enlarged.

Description

technical field [0001] The invention relates to an isolating switch arrangement structure for an AIS substation power distribution device. Background technique [0002] According to different insulation types of equipment, substation power distribution devices can be divided into GIS (Gas Insulated Switchgear, gas insulated fully enclosed switch), HGIS (Hybrid Gas Insulated Switchgear, mixed gas insulated switch), AIS (Ais Insulated Switchgear, air insulated switch) Three types, currently the most widely used are GIS and AIS power distribution devices. Among them, the GIS power distribution device is reliable in operation, compact in layout, and occupies a small area. Larger, not suitable for tight urban areas. HGIS equipment is between AIS and GIS, and its type is basically the same as GIS, but does not include bus equipment. Because the area is much larger than GIS, the investment savings are limited compared with GIS, and the application range is small. [0003] Subst...
