Embodiment Construction

[0019] Please refer to the accompanying drawings, a switch device 10 according to a preferred embodiment of the present invention has a first terminal 12A and a second terminal 12B. The first terminal 12A and the second terminal 12B are respectively connected to corresponding electrical conductors (not shown), such as a power line, a bus or a part thereof. In this embodiment, for example, the first terminal 12A can be connected to a part of the power supply system (not shown), and the second terminal 12B can be connected to a feeder for an electronic device (not shown) or other components of the system. Some provide power.

[0020] The switch device 10 further includes a switch 14 and a selector 16 connected to the switch 14 . The switch 14 is used for electrically connecting or disconnecting the first terminal 12A and the second terminal 12B. Specifically, the switch 14 includes a plurality of first electrical contacts 15A and second electrical contacts 15B. At least one o...

Abstract

A switching apparatus for use with multi-phase electrical supply systems comprising a switch device comprising first and second contacts that are actuatable between an open state and a closed state by switch actuation means; a selector device coupled to the switch device and comprising a movable contact that is actuatable between at least two states by selector actuation means; and a base. The switch device and the selector device extend from the base, and at least part of the switch actuation means and at least part of the selector actuation means are provided at the base. The selector actuation means comprises a drive shaft coupled to the drive means, the drive shaft extending from the base along the selector device actuation axis.

Description

technical field [0001] The invention relates to a switchgear of a power supply system, in particular to a switchgear applied to a switchgear of the power supply system. Background technique [0002] As an existing switch device, a draw out circuit breaker (DOCB) has the functions of switching and isolation. The withdrawable circuit breaker is movable between a connection position and a disconnection position relative to a switch cabinet housing. In the connected position, the withdrawable circuit breaker performs the function of a switch through the normal operation of the circuit breaker. In the disconnected position, the withdrawable circuit breaker provides the isolation function. The withdrawable circuit breaker usually includes an interlock mechanism to prevent the circuit breaker from closing when the withdrawable circuit breaker is in the intermediate position (between the connected position and the disconnected position), and to prevent the withdrawable circuit bre...
