Abstract

A medium voltage switchgear or control gear includes at least one first compartment; a cable compartment; a plurality of main components; and a plurality of auxiliary components. The plurality of main components is housed in at least one part of the at least one first compartment. The plurality of auxiliary components is housed in the cable compartment. The second connector is configured to connect to the first connector to connect a cable in the cable compartment to a component of the plurality of main components. The cable compartment is configured to be disconnected from the at least one first compartment and wherein the cable compartment is configured to be spatially separated from the at least one first compartment.

First claim

What is claimed is:

1. A medium voltage switchgear or control gear, comprising:
at least one first compartment comprising a side configured to provide a closed portion of the at least one first compartment;
a plurality of main switchgear or control gear components housed in the at least one first compartment, the plurality of main switchgear or control gear components comprising:
a first connector affixed to the side configured to provide the closed portion, and
at least one component of the plurality of main switchgear or control gear components connected to the first connector, the at least one component comprising a main busbar system, a circuit breaker, or a disconnector;

a cable compartment comprising an open side; and
a plurality of auxiliary switchgear or control gear components housed in the cable compartment, the plurality of auxiliary switchgear or control gear components comprising:
a medium voltage cable,
a second connector connected to the medium voltage cable, the second connector configured to be accessible through the open side of the cable compartment when the cable compartment is disconnected from the at least one first compartment and configured to connect to the first connector through the open side thereby connecting the medium voltage cable to the at least one component of the plurality of main switchgear or control gear components,
a cable connection bar having a first end and an opposing second end, the first end configured to connect to the second connector and the second end configured to connect to the medium voltage cable, and
a holder configured to hold the cable connection bar and the second connector in a connection position when the second connector is disconnected from the first connector, and configured to be removable when the second connector is disconnected from connected to the first connector,

wherein, when the at least one first compartment is connected to the cable compartment, the closed portion of the at least one first compartment is configured to cover the open side of the cable compartment, and
wherein, when the at least one first compartment is disconnected and spatially separated from the cable compartment, the first connector is configured to be disconnected from the second connector and the second connector is configured to be exposed through the open side of the cable compartment and enable access of the cable compartment through the open side.

2. The medium voltage switchgear or control gear according to claim 1 , wherein when the cable compartment is connected to the at least one first compartment, the medium voltage switchgear or control gear is configured to provide an arc proof outer surface.

3. The medium voltage switchgear or control gear according to claim 1 , wherein, when the cable compartment is connected to the at least one first compartment, the cable connection bar is configured to be held in the connection position by the holder.

4. The medium voltage switchgear or control gear according to claim 1 , wherein the holder is compatible with medium voltage operation within the medium voltage switchgear or control gear.

5. The medium voltage switchgear or control gear according to claim 1 , wherein a supporting template within the cable compartment is configured to fix the holder at a defined position.

6. The medium voltage switchgear or control gear according to claim 5 , wherein the supporting template is configured to be removed from the cable compartment.

7. The medium voltage switchgear or control gear according to claim 5 , wherein the supporting template is compatible with medium voltage operation within a within the medium voltage switchgear or control gear.

8. The medium voltage switchgear or control gear according to claim 1 , wherein the first connector is directly connected to or is part of the at least one component of the plurality of main switchgear or control gear components.

9. The medium voltage switchgear or control gear according to claim 1 , wherein the at least one first compartment comprises a plurality of compartments.

10. The medium voltage switchgear or control gear according to claim 1 , wherein the first connector comprises a threaded hole and the second connector comprises a screw, or the first connector comprises the screw and the second connector comprises the threaded hole.

11. A medium voltage switchgear or control gear, comprising:
at least one first compartment;
a plurality of main switchgear or control gear components housed in the at least one first compartment, the plurality of main switchgear or control gear components comprising: at least one component of the plurality of main switchgear or control gear components, the at least one component comprising a main busbar system, a circuit breaker, or a disconnector;
a cable compartment comprising:
a first part fixedly attached to the at least one first compartment, the first part comprising a first connector connected to the at least one component of the plurality of main switchgear or control gear component, and
a second part having at least one open side, the second part comprising:
a plurality of auxiliary switchgear or control gear components housed in the second part of the cable compartment, the plurality of auxiliary switchgear or control gear components comprising:
a medium voltage cable,
a second connector connected to the medium voltage cable, the second connector configured to be accessible through the at least one open side of the second part of the cable compartment when the second part of the cable compartment is disconnected from the first part of the cable compartment and configured to connect to the first connector of the first part of the cable compartment thereby connecting the medium voltage cable to the at least one component of the plurality of main switchgear or control gear components,
a cable connection bar having a first end and an opposing second end, the first end configured to connect to the second connector and the second end configured to connect to the medium voltage cable, and
a holder configured to hold the cable connection bar and the second connector in a connection position when the second connector is disconnected from the first connector, and configured to be removable when the second connector is disconnected from connected to the first connector,

wherein, when the first part of the cable compartment is connected to the second part of the cable compartment, the second part of the cable compartment is configured to close the first part of the cable compartment, and
wherein the second part of the cable compartment is configured to be spatially separated from the first part of the cable compartment, the first connector is configured to be disconnected from the second connector, and the second connector is configured to be exposed through the at least one open side of the second part of the cable compartment and enable access of the second part of the cable compartment through the at least one open side of the second part of the cable compartment.
