Embodiment Construction

[0041] Figure 1 to Figure 2 An example of a three-phase switchgear or control device for operation in a low, medium or high voltage substation is shown.

[0042] One example relates to a three-phase switchgear or control device 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; Multiple components for third phase. The components for the first phase, second phase and third phase each include connections to: main busbar 7 , breaker actuator 1 , single phase breaker pole 3 and cable connection 6 . The breaker actuators and single-phase breaker poles for the first phase are oriented along a first axis. The breaker actuators and single-phase breaker poles for the second phase are oriented along the second axis. The breaker actuator for the third phase and the single phase breaker poles are oriented along the third axis. The first axis, the second axis and the third axis are inclined...

Abstract

The invention relates to a three-phase switchgear or control device 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 various components for the third phase. A number of components for phase one, phase two and phase three each include connections to: main busbar (7), breaker actuator (1), single phase breaker pole (3) and cables Connector (6). The breaker actuators and single-phase breaker poles for the first phase are oriented along a first axis. The breaker actuators and single-phase breaker poles for the second phase are oriented along the second axis. The breaker actuators and single-phase breaker poles 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. A plurality of components for the first, second and third phases are housed in at least one compartment.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of the filing date of European Patent Application No. EP18214196.0 filed on December 19, 2018, the entire content of which is incorporated herein by reference. technical field [0003] The invention relates to a three-phase switchgear or control device for low-voltage, medium-voltage or high-voltage applications in substations. Background technique [0004] In state-of-the-art designs of switching devices and control gears (also referred to as control gears), primary circuits of three phases are arranged in parallel with each other. There is one common drive mechanism for the circuit breakers, one common drive for the disconnectors, and one common drive for the earthing switches of all three phases. [0005] Such an arrangement can be problematic for handling and maintenance purposes and has an associated risk of internal arc faults in the complete power circuit. [0006] There is...
