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.

Claims (43)

1 . A switchgear comprising:

a cable compartment enclosed by walls and a cover;

a cable connector arranged in the cable compartment and configured to electrically connect a cable to a cable bushing located in the cable compartment,

wherein the cable connector comprises:

a first portion to which the cable is connected; and

a second portion extending perpendicular to the first portion and having a first end connected to the cable bushing and a second end opposite to the first end; and

a metal plate arranged inside the cable compartment and comprising a main body arranged adjacent the first portion,

wherein the metal plate further comprises a support portion supporting the second portion at a position adjacent the second end;

wherein a shortest distance between the main body and an outer surface of the first portion is in a range of 0 to 10 mm.

2 . The switchgear of claim 1 , wherein the shortest distance between the main body and the outer surface of the first portion is 0 mm.

3 . The switchgear of claim 1 , wherein the metal plate further comprises a bending portion extending from the main body towards the cable;

wherein the first portion comprises an end for connecting the cable; and

wherein a shortest distance between the bending portion and the end of the first portion is in the range of 0 to 10 mm.

4 . The switchgear of claim 3 , wherein the bending portion comprises a notch accommodating the cable.

5 . The switchgear of claim 1 , wherein the main body extends vertically and is positioned between the first portion and the cover.

6 . The switchgear of claim 1 , wherein two or more cable connectors are connected to the cable bushing in series; and

wherein two or more metal plates are arranged and the main body of each metal plate is arranged adjacent a corresponding first portion.

7 . The switchgear of claim 1 , wherein a first end of the main body is fixed to a roof wall of the walls.

8 . The switchgear of claim 1 , wherein three cable connectors are respectively connected to a respective cable of three-phase cables; and

wherein the metal plates for the three-phase cables are formed as an integrated plate.

9 . The switchgear of claim 1 , further comprising a bus compartment located above the cable compartment, the bus compartment comprising:

a bus bar and a busbar bushing;

a bus connector connecting the bus bar to the busbar bushing;

a further metal plate arranged inside the bus compartment and positioned around the bus connector;

wherein a shortest distance between the further metal plate and the bus connector is in the range of 0 to 10 mm.

10 . The switchgear of claim 9 , wherein the further metal plate is comprises a hole.

11 . The switchgear of claim 9 , further comprising:

a circuit breaker compartment located between the bus compartment and the cable compartment; and

a venting channel for venting gases out of the switchgear upon occurrence of an arc fault in the cable compartment or the bus compartment.

12 . The switchgear of claim 1 , wherein the thickness of the cover is up to 3 mm.

13 . The switchgear of claim 12 , wherein the cover is made of a single-layer metal plate.

14 . The switchgear of claim 1 ,

wherein the metal plate further comprises an opening for receiving the first portion.

15 . A switchgear comprising:

a cable compartment enclosed by walls and a cover;

a cable connector arranged in the cable compartment and configured to electrically connect a cable to a cable bushing located in the cable compartment,

wherein the cable connector comprises a first portion to which the cable is connected;

a metal plate arranged inside the cable compartment and comprising a main body arranged adjacent the first portion; and

a bus compartment located above the cable compartment, the bus compartment comprising:

a bus bar and a busbar bushing;

a bus connector connecting the bus bar to the busbar bushing; and

a further metal plate arranged inside the bus compartment and positioned around the bus connector,

wherein a shortest distance between the further metal plate and the bus connector is in a range of 0 to 10 mm.
