"Control room for transformer stations in electricity supply networks"

Substations in electricity supply networks · are of appropriate Control rooms are monitored and controlled. It is known to have control, unlocking and feedback lines the switchgear of a fast & ddes to a marshalling panel to connect. The marshalling panel is equipped with a multiple

number of individual relays connected, e.g. in so-called Auxiliary relay rails' are accommodated. Single wires for feeding through locking, Feedback, synchronization and control conditions are switched. A control panel can also be found on the marshalling panel and a telecontrol device must be connected.

A substation control room according to the state of the art mentioned has the disadvantage that the necessary interconnection -a large number of Individual wires in the marshalling panel according to the installation plans at the installation site must take place, which gives rise to many possible errors In addition, there are cost-consuming test runs before every start-up necessary.

The innovation has therefore -the task · set; a control room to create for substations in Elektrizitätsv'ersprgungsnetzen, with the interlocking, feedback, synchronizing and i? ndungen are preconnected. '. ■

I> he innovation has the advantage that no single wire connections are necessary at the installation site and thus the possible occurrence of circuit errors is eliminated. Furthermore is for the relay cards the use of standardized switch card sizes and standardized switchgear cabinets possible, so that development costs for the mechanical No assembly required.

The innovation is shown symbolically in the drawing. Figure 1 shows the symbol representation of a substation according to the innovation.j In Figure 2 are built-in grip strips of relay cards Drawn in supervision for feedback conditions.

Switching devices 1 of a control panel 2 have control, unlocking and feedback lines 3 which are routed directly or collectively via a control cabinet Q to relay cards 5. A connection between the individual relay cards of individual switch panels 2 is interconnected within the mechanical structure of the relay cards 5. The relay cards are advantageous. 5 mechanically constructed in standard cabinets (not shown), which can accommodate more relay cards 5 than are currently necessary, so that when the system is expanded with additional switch panels, relay cards only need to be plugged in. The necessary cross-connections between possible switch panels are then already connected in advance.

The relay cards 5 are still, via lines 6 with a Control panel 7 connected. In addition, remote control, e.g. of network control centers, is possible via suitable telecontrol devices 8. possible via the cable connection 9.

In Figure 2, the handle strips 10, 11, 12, 13, 14 of relay cards, for return conditions advantageously 'with return, meldebildprn 15, 16, 17, 18, 19 of the respective switch field provided so that a, each complete Plant is obtained, namely, since the relay cards 5 in a row according to functions and columns according to .Schschfeldern in which not drawn standard cabinet are arranged. while the handle strips 10, i.1, 12, 13 »" 14 the columns of the individual Represent switch panels of the substation.

Claims (4)

: iit ■: claims for protection 1. Control room for substations in electricity supply networks, through this. characterized in that one relay card for the locking, feedback, Synchronization and control conditions of a switching field provided is (Figure 1). spifueii 1, wobsi the relsislcartsn in Standard cabinets are constructed mechanically, thereby marked that the standard cabinets more Can accommodate relay cards than are necessary for the initial expansion of the substation. 3. Control room according to claim 1 and 2, characterized marked that the relay cards are columnar according to panels (10, 11, 12, 15, 14) and aeilen are arranged according to function * 4. Control room according to claim 1 "to 3» thereby characterized that the individual relay cards for the feedback conditions with a handle bar (10) are provided, which carries a feedback image of the respective control panel (15).
