The power distribution box may include one or more outlets coupled to one or more portions of the one or more panels of the housing. The power distribution box may include one or more output plugs configured to receive one or more power distribution whips. The one or more output plugs may be configured to couple to one or more portions of the one or more panels of the housing. The power distribution box may include one or more circuit breakers coupled to one or more portions of the one or more panels of the housing. The power distribution box may include at least one power whip coupled to an output plug of the one or more output plugs.
Abstract:
El centro de transformación incluye un equipo de alta tensión (1), un transformador (2) y un cuadro de baja tensión (3), conectados consecutivamente entre sí en el orden referido, de manera que dichos tres componentes forman un conjunto o unidad compacta al estar el equipo de alta tensión (1) y cuadro de baja tensión (3) montados directamente sobre la tapa de dicho transformador. El conexionado entre el equipo de alta tensión (1) y el transformador (2) se realiza directamente a través del módulo de protección (7) con que van equipados los centros de transformación eléctrica, mientras que el conexionado entre el transformador (2) y el cuadro de baja tensión (3) se realiza también directamente a través de una prolongación vertical de la tapa del transformador, a modo de torreta (6), de la que acceden al exterior las conexiones (12) al transformador y a las que se conectan directamente los embarrados del cuadro de baja tensión (3).
Abstract:
The present invention relates to a high-voltage switchgear station comprising a plurality of electric apparatus. According to the invention, the electric apparatus are arranged in an air-insulated, earthed metal enclosure (1). The invention also relates to a switchgear module for use in such a switchgear station. The module according to the invention comprises a metal enclosure (1) with air-insulated electric apparatus enclosed therein. The invention also relates to a method of constructing a high-voltage switchgear station. According to the method, the switchgear station is built out of modules according to the invention, the apparatus therein being connected together, and the metal enclosures being earthed.
Abstract:
A feeder power source (1) for a network power system (10) includes a network transformer (12) having a delta three-phase primary winding (18) and a three-phase secondary winding (72); a three-phase primary feeder (6) electrically connected to the delta three-phase primary winding; a three-phase secondary bus (77) electrically connected to the three-phase secondary winding; and a three-phase electrical switching apparatus (4) structured to open and close the three-phase primary feeder. A network protector (62) includes a network relay (64) and a three-phase circuit breaker (76) structured to open and close the three-phase secondary bus. A first circuit (2;20;34) is electrically connected between at least one phase of the three-phase primary feeder and ground, and is structured to unbalance shunt impedance to the three-phase primary feeder ground. A second circuit (40) detects a shift in system neutral (N) and detects that the three-phase primary feeder is opened by the three-phase electrical switching apparatus.
Abstract:
The invention relates, amongst others, to a local network station (50-58). According to the invention, the local network station comprises an internal data bus (230), to which a central communication device (240) of the local network station and at least one sensor and at least one actuator are connected by means of a respective data bus interface, the central communication device is suited to receive an operating state signal of the at least one sensor via the internal data bus and forward same to an external control device via an external communication system, and the central communication device is further suited to receive control commands of the external control device via the external communication system and to forward same to the at least one actuator via the internal data bus.
