    摘要: The present invention relates to a three phase switchgear or control gear, comprising at least one compartment (2, 11, 12, 13, 14), a plurality of components for a first phase, a plurality of components for a second phase, and a plurality of components for a third phase. The plurality of components for the first phase, the second phase and the third phase each comprise a connection to a main busbar (7), a circuit breaker actuator (1), a single phase circuit breaker pole (3), and a cable connection (6). The circuit breaker actuator and the single phase circuit breaker pole for the first phase are oriented along a first axis. The circuit breaker actuator and the single phase circuit breaker pole for the second phase are oriented along a second axis. The circuit breaker actuator and the single phase circuit breaker pole for the third phase are oriented along a third axis. The first axis, the second axis and the third axis are inclined to each other. The plurality of components for the first phase, the second phase and the third phase are housed in the at least one compartment.

    摘要: A voltage monitoring device comprises input connectors for receiving an input voltage, a linkage (7, 8, 14), a spring (12) for urging the linkage (7, 8, 14) towards a first stable position, and a solenoid (5) powered by the input voltage and adapted to displace the linkage (7, 8, 14) from the first position to a second position if a voltage applied to the solenoid (5) exceeds a first threshold, and to maintain the linkage in the second position while the voltage applied to the solenoid exceeds a second threshold lower than the first threshold. A switch (22) controlled by the linkage (7, 8, 14) is connected to the input connectors and to the solenoid (5) so as apply a first percentage of the input voltage to the solenoid (5) while the linkage (7, 8, 14) is in the first position and to apply a second percentage of the input voltage (Vcc) to the solenoid (5) while the linkage (7, 8, 14) is in the second position, the second percentage being less than the first percentage.

    摘要: The present invention relates to a switchgear or control gear, comprising at least one first compartment (2, 8, 12), a second compartment (1), a plurality of main switchgear or control gear components, and a plurality of auxiliary switchgear or control gear components. The plurality of main switchgear or control gear components comprises a main busbar system (3), a three position linear or rotational movement disconnector (4), a circuit breaker (5), and a cable connection. The plurality of auxiliary switchgear or control gear components comprises a disconnector drive (11) and a circuit breaker drive (10). The plurality of main switchgear or control gear components are housed in the at least one first compartment. The plurality of auxiliary switchgear or control components are housed in the second compartment. The circuit breaker and three position linear or rotational movement disconnector are mounted vertically in the at least one first compartment.
