Abstract: A switchgear which includes a cable compartment enclosed by walls and a cover, and a cable connector arranged in the cable compartment. The cable connector is configured to electrically connect a cable to a cable bushing located in the cable compartment. cable connector includes a first portion to which the cable is connected and a metal plate arranged inside the cable compartment. The shortest distance between a main body and an outer surface of the first portion is in the range of 0 to 10 mm.

Abstract: A switchgear which includes at least one three-position disconnector arranged in a gas-tight space of a frame. Each phase of the disconnector includes first, second, and third fixed contacts and a moving contact. The first fixed contact is directly connected to a main busbar, so that the conductive main circuit has shorter wiring, saving floor space, and conductor materials. An outer surface of the moving contact is provided with a slot extending in an axial direction to accommodate rolling elements, which guide the moving contact to move through the second fixed contact and prevent it from rotating. The moving contact is provided with grooves, which accommodate contact pieces to realize connection with the corresponding fixed contact. The moving contact of each disconnector is coupled to the same drive shaft so that it is connected to an external operating mechanism via only one sealing point on the frame.

Abstract: Embodiments of the present disclosure relate to a switch device, comprising: a first three-position switch; a second three-position switch disposed below the first three-position switch; a circuit breaker disposed between the first three-position switch and the second three-position switch. A first interlock unit is disposed above the circuit breaker and connected to the circuit breaker and the first three-position switch, and configured to block a manual operation of the first three-position switch in a closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the first three-position switch is manually operated in an open state of the circuit breaker. A second interlock unit is disposed below the circuit breaker and connected to the circuit breaker and the second three-position switch, and is configured to block a manual operation of the second three-position switch in the closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the second three-position switch is manually operated in the open state of the circuit breaker.
