Die Verbindung des aktiven Leiters L’ mit dem aktiven Leiter L der Einspeisung kann durch den von der Steuervorrichtung The compound of the active conductor L ‘with the live conductor L of the feed can be done by the control device 5 5 gesteuerten Schalter controlled switch 4 4 unterbrochen bzw.
Emergency lighting system with special Endstromkreistopologie and endstromkreisbildende switching units. DE DEB4 en Electrical installations design, selection and erection. According to the invention a feed line z. Installation system for low-voltage LV distribution system electrical components. B pathway lighting to illuminate escape routes. For fire protection conditions, it is still often advantageous to encase the distribution box that integrity is guaranteed against the effects of fire.
Spring clamp connections – General requirements, test methods and practical guidance. Equipment protection by increased safety “e”. In einem Verteilerkasten wird aus der Zentrale der Ersatzstromversorgung eine Versorgungsleitung In a distribution box is removed from the center of the backup power supply is a supply line 1 1 angeschlossen, die in Dauerschaltung geschaltet ist. Roofed swimming pools and open air swimming baths. Equipment protection by intrinsic safety “i”.
Two conductors are always connected to the power and the backup power supply, the other two conductors only be switched due to a switch-on. Steuerstromkreise beschrieben Bild 1. Device for supplying power to a multi-voltage electrical system of a motor vehicle.
Thus, it is so common to go to a supplied through the emergency room area with at least 4 final circuits, two final circuits for Continuous and standby mode and two circuits for the alternate supply of the lamps. Emergency lighting system for buildings and rooms with official nature, has lights of different operating phases, where emergency lighting system is connected to supply line and switch units are arranged in fire area.
Mounting platform for electricity meter unit, has rapid coupling for connecting unit electrically and mechanically without tools; unit is moved parallel to platform to locking position. The installation cost of the final circuits is only slightly increased by the fact that now 5-pole cables must be used instead of the previously required 3-pole lines.
The final circuits such emergency lights contain a limited number of luminaires for. Conveyor transport system with number of separate sections – has separate motor drive and controller for each section with sensor inputs and communication between adjacent controllers.
For this purpose, in each output circuit of the junction box fuses are arranged, which cause not a short circuit in one end circuit further supplied from the distribution end circuits to be disturbed. Application deemed withdrawn, or ip right lapsed, due to non-payment of renewal fee.
Es ist nach VDE erforderlich, die Leuchten derartiger Stromkreise auf zwei gesondert abgesicherte Stromkreise, alternierend angeordnet, aufzuteilen. PVC insulated cables and sheathed power cables for rated voltages up to and including. Thus the need for an alternate installation required two circuits are only moved from the distribution box.
According to the invention an error ve by a fire short-circuit in the supply line to the final circuits to the additional fuses in the origin of the supply line does not affect the teul back-up power supply.
The final circuits are based on the prior art either constantly supplied with power or only when necessary, so that the lights off in accordance with its operating conditions and can be eliminated. However, this requires a high technical expenditure and is correspondingly susceptible to faults.
The invention is further illustrated by the images.
German DIN VDE Standards –
Is switched parallel to the first circuit. In undisturbed panel power supply is located on the supply line to the mains voltage, an optionally present protective conductor is not shown.
Circuitry for emergency lighting according to claim 1 or 2, characterized in that NL-L ‘the two end circuit common to the combined final circuits LN, L N have a common return conductor N have.
Dies erfordert jedoch sowohl Eingriffe in der Zentrale der Stromversorgung als auch in den einzelnen Leuchten, wiederum ein hoher Aufwand.
CONTA-CLIP – IEC/EN richtlijnen
Plane Welding PN Equipment protection by type of protection “n. Advantageous embodiments and further developments are contained in the dependent claims.
General requirements and particular requirements for clamping units for conductors from 0,2 mm2 up to 35 mm2 included. Rooms containing electrical sauna-heaters – installations site. Fundamental principles, assessment of general characteristics, definitions.
Are connected to the final circuit L’-N for the lighting circuit in readiness. Ancillary equipment – Protective conductor terminal blocks for copper conductors. At the output of the junction box is now located at least two separately fused final circuits each having a first and a second circuit for operating the lamp in continuous circuit with the stationary always under tension phase L and the return conductor N and a second circuit for operating the lamp in standby circuit with the connected phase L ‘and N as a common return conductor.
Is a function preserving against the effects of fire line. The respective output circuits are in turn divided into a first and a second circuit.
From these terminals from the lamp circuit of the lamp is powered. For this purpose, the individual lights can be equipped with modular components that perform centralized commands.
Sicherheitsbeleuchtung mit Tdil enbatterie. This in turn requires a high installation cost, if the control panel and the lighting of the final circuits are arranged at a greater distance.
Ancillary equipment – Terminal blocks dun copper conductors. Ancillary equipment – Safety requirements for fuse terminal blocks. Die jeweiligen Ausgangsstromkreise werden wiederum in einen ersten und einen zweiten Stromkreis unterteilt.
Both circuits are used for protection against overcurrents to final circuits, because a fault in a circuit not affected by the inventive arrangement of fuses S1, S2, S3 and S4, the function of the second circuit. According to the invention the required according to the prior art lead to the emergency lights with 4 final circuits is replaced by a single supply line with subsequent distribution box for the connection dinn the now shortened and reduced in the number of lines of the final circuits.
