Embodiment Construction

[0030] Fig. 1 is a cross-sectional view of the control module STM along the X-Y section line in Fig. 2, from which the "sandwich" sandwich structure of the control module STM can be seen especially. The control module STM has an intermediate plate MBL, in the recesses of which are accommodated an indicator slide AZS of a power switch (not shown) and a blocking slide VRS of a disconnector switch and a grounding switch (also not shown). The front side of the middle plate MBL is bounded by the cover plate ABL, and on the equipment side by the guard plate HBL. The control block area SKB is indicated by dashed lines, in which the switching levers necessary for controlling the power switches as well as the grounding and disconnecting switches are respectively installed.

[0031] Also shown in this view are the guide openings FUO in the center plate MBL which are adapted to the positions and contours of the indicator slides AZS and locking slides VRS and the positions of the indicato...

Abstract

The invention relates to position indicating devices and position locking devices for power circuit breaker systems, especially for air-insulated medium-voltage switchgears, having the following functional characteristics: ''power switching'', ''disconnecting'' and ''grounding''. The position indicating devices and position locking devices are integrated together in control modules (STM) and are realized in the form of indicating slides (AZS) and locking slides (VRS). Said middle plate is arranged between a front cover plate (ABL) and a holding plate (HBL) which faces the interior of the power circuit breaker systems. The middle plate (MBL), the cover plate (ABL) and the retaining plate (HBL) comprises a number of guide openings (FUO) which are adapted to the positions and contours of the indicating slides (AZS) and of the locking slides (VRS), a number of viewing openings (BEO) and a number of continuous openings (DUO).

Description

technical field [0001] The invention relates to a known device for displaying and locking the switching positions of a power switchgear, in particular an air-insulated medium-voltage switchgear with the functional characteristics "power switch", "isolation" and "grounding". Background technique [0002] A large number of power switching devices with these functional features are known correspondingly according to the relevant provisions of VDE 0670 part 1000 for position indication devices for power switches with disconnector function and earthing switch function and according to VDE 0670 part 6 ( Blocking devices / recommendations) are designed for the relevant provisions of blocking devices to exclude functions at the same time. [0003] The switching position indication device and the functional locking device of the power switching device are, for example, indicated by DE 44 45 081 A1, which are controlled to a large extent by separate levers and which correspond to differ...
