For systems with Umgehungssc.hie.neji kpmmen still patent claims: mais interlocking conditions added. From the examples given for interlocking conditions, 1. Method for controlling any number that applies to the entire system, i.e. the individual electrically controllable electrical switch, superordinate with 5 field-internal interlocking conditions from which each controlled switch has a position (higher-level interlocks), it is clear that signaling contact to control the loud switch as permanent signals during a program The following switch introduces must be constantly available after guidance. Ande patent 1540 072, if so marked, there are more or less large parts of this net that the higher-level interlocking conditions are continuous signals depending on the of each system group (1, 2) via the program through complex program-dependent To connect contacts (.53) each of a connection relay (.5) to the devices. If there are several switchgear busbars in a switchgear, common to all system groups (3) are switched and that the groups, for example with different chip switching relays (.5) of each Ajilagengruppe over 15 connections, are to be switched program-controlled, additional control contacts (.. 1, ...) of each then is with regard to the relatively large Field selection switch (2.1 ... 2.m) of this number of systems - different continuous signals for each group being controlled. location group has its own program control 2. The method according to claim 1, thereby moderately. One common for all system groups indicates that the excitation of each progression would 20 program control with the conventional switching relay (.5) via interlocking contacts (.52) methods an uneconomically large effort of all other relay relays (.5). ergeoen, since the program control by itself 3. The method as claimed in claim 1, characterized in that it cannot identify which continuous signals indicate that the field selection switches include a system group in which a program (2.1 .. .2.m) controlled relays (2.11 ... 4.11 ) 25 is performed. It would therefore be necessary to manually preselect the permanent signals for programs to be blocked using collective signals for a system group that is blocked with a normally open contact (.212; .312; .412). This method is cumbersome, illuminated (210; 310; 410) to influence the special when the program control is operated via program selection and the program sequence, because a telecontrol system is operated. 30 the larger telegram content has a larger 4. The method as claimed in claim 3, characterized in that it is required for the telecontrol system. It also indicates that the potentials of the additional busbars (210, 310, 410) can run as blocking potentials or program faults can occur in this separate preselection, the control that the preselection of the associated continuous signals under the current path of the programs to be blocked Switching coils in the relay block (5) 35 remains. Another difficulty arises from influencing or skipping switching that at least the continuous signals of various stages are placed on the busbars (70.1 ... 70.5) of the layer groups, but often also those of a system group, relay blocks (7). belong to different circuits that must not be connected to one another. 40 Another type of signal that can be counted among the permanent signals are the program blocking signals for certain fields. Example there are errors that cannot be switched off by the program control. Other FeI-45 which in turn are blocked for replacement switch programs, so-called ESB programs, for those under Use of a bypass rail to replace the circuit breaker in a bay with that of the coupling The invention relates to a method of controlling. Finally, such fields should be mentioned any number of electrically controllable electrical so in which z. B. the outgoing disconnector is missing, which is in Trafoscher Switch where every controlled switch is common over fields. When running the program in a position signaling contact to control the according to these fields must be the switching stage for the outgoing switching program initiates the following switch. separators can be skipped. The use of program controls in switching In the rarest of cases, the individual connections are systems has the task of removing the switching personnel 55 the same structure with regard to the loads and the switching processes depending on the number of busbars, so that - overall, the interlocking conditions in the shortest possible time - each system group can be carried out through such a time. For "On" and "Off" switching, a multitude of special features from any other program is sufficient in many cases to distinguish the locking position group that with the known management conditions of the field in which a switching program is carried out with an economically justifiable effort is sufficient target. If there is no common busbar earthing system for several system groups, program control can be built,
