摘要:
The invention pertains to an air-insulated middle voltage switching station, comprising a number of feedthrough post insulators (FPI) provided with busbar connections (BBC), which number corresponds to the number of phases, whereby said feedthrough post insulators (FPI) are removably connected to a post insulator supporting sheet (PISS). The inventive feedthrough post insulators (FPI) have a square outer edges(SOE) connected to square inner edges (SIE) between which clamping slots with concentric transverse edges (CTE) are provided. In the bearing area relative to the post insulator supporting sheets (PISS), the post insulators inner edges (PISE) contains post insulator guiding edges (PIGE), which go across cavities in the post insulator supporting sheets (PISS) and grows smaller into a trapezoid in the direction of the free area, with longitudinal surfaces (SL) facing the post insulator outer edges (PIOE).

The invention relates to a metal-clad, air-insulated medium voltage switchboard plant with one or more functional zones for receiving switchgear and/or cable connections and/or bus bars. The medium voltage switchboard is realized by means of a switchboard section (MSF...) having modular structure and a plant-oriented number of separate partition areas (SCR...) with separate pressure relief devices (DEE...). Said partition areas (SCR...) are interconnected with function-oriented bushing devices (DEE...). The switchboard sections with modular structure are used for realizing metal-clad air-insulated medium voltage switchboard plants used for energy supply and distribution.

The invention relates to an air-insulated metal-encapsulated middle voltage switching station, comprising a number of bushing-type current transformers (BCT) provided with cable connections (CC), which number corresponds to the number of phases. Said bushing-type current transformers (BCT) are removably connected to a transformer supporting sheet (TSS). The inventive bushing-type current transformers (BCT) have square outer edges (SOE) connected to square inner edges (SIE) between which slots with concentric transverse edges (CTE) are provided for clamping said transformers. In the bearing area relative to the post insulator supporting sheets (PISS), the transformer inner edges (TIE) have transformer guiding edges (TGE) and grow smaller into a trapezoid in the direction of the free area, with longitudinal surfaces (LS) facing the transformer inner edges (TIE).

The invention relates to switching stations comprising power switching devices, especially air-insulated medium-voltage switching stations, comprising busbars and cable branches for supplying and distributing power. The power switching devices (LE) each contain a contact unit (KE) and a switching tube (SR), whereby the contact units (KE), inside the power switching devices (LE), can be connected with earth potential bars (ES) according to need, and the contact units (KE), inside the switching stations (SA), can be connected to the busbars (SS) and to the cable branches (KA) according to need.
