Abstract

A switchgear or control gear includes: at least one first compartment; at least one second compartment; a plurality of main switchgear or control gear components including a main busbar system, a three position linear or rotational movement disconnector, a circuit breaker, and at least a first part of an insulated cable connection; and a plurality of auxiliary switchgear or control gear components including a disconnector drive and a circuit breaker drive. The plurality of main switchgear or control gear components are housed in the at least one first compartment. The plurality of auxiliary switchgear or control gear components are housed in the at least one second compartment. When one or more of the plurality of main switchgear or control gear components is energized, the at least one first compartment is hermetically sealable or maintainable at an internal air pressure greater than ambient air pressure.

First claim

What is claimed is:

1. A switchgear or control gear, comprising:
at least one first compartment wherein the at least one first compartment comprises a plurality of first compartments;
at least one second compartment wherein;
a plurality of main switchgear or control gear components comprising a main busbar system, a three position linear or rotational movement disconnector, a circuit breaker, and at least a first part of an insulated cable connection; and
a plurality of auxiliary switchgear or control gear components comprising a disconnector drive and a circuit breaker drive,
wherein the plurality of main switchgear or control gear components are housed in the at least one first compartment,
wherein the plurality of auxiliary switchgear or control gear components are housed in the at least one second compartment,
wherein when one or more of the plurality of main switchgear or control gear components is energized, the at least one first compartment is configured to be hermetically sealed or maintained at an internal air pressure greater than ambient air pressure, and
wherein when the plurality of main switchgear or control gear components are de-energized, the at least one first compartment is configured to enable an operator to access an interior of the at least one first compartment, and
wherein a primary compartment of the plurality of first compartments comprises a cable connection compartment within which is housed a second part of the insulated cable connection and a voltage sensor and a current sensor, and
wherein the circuit breaker is housed in a secondary compartment of the plurality of first compartments other than the cable connection compartment.

2. The switchgear or control gear according to claim 1 , wherein the at least one first compartment is arc proof.

3. The switchgear or control gear according to claim 1 , wherein the at least one first compartment complies with IP43 standards.

4. The switchgear or control gear according to claim 1 , wherein the at least one first compartment complies with IP54 standards.

5. The switchgear or control gear according to claim 1 , wherein the at least one first compartment is not configured to be filled with SF6 gas for operational purposes.

6. The switchgear or control gear according to claim 1 , wherein when the one or more of the plurality of main switchgear or control gear components is energized, the at least one first compartment is not filled with SF6 gas.

7. The switchgear according to claim 1 , wherein at least one sensor is located in the cable connection compartment, and wherein the at least one sensor is configured to monitor the components in the cable connection compartment.

8. The switchgear or control gear according to claim 1 , wherein a second part of the insulated cable connection and a voltage sensor and a current sensor are housed in the at least one second compartment.

9. The switchgear or control gear according to claim 1 , wherein at least one sensor is located in the at least one second compartment, and wherein the at least one sensor is configured to monitor the components in the at least one second compartment.

10. The switchgear or control gear according to claim 1 , wherein the main switchgear or control gear components comprises one or more of: an earthing switch, voltage indication, surge arrestor, UFES, IS-limitor, contactor, load-break switch, or fuse.

11. The switchgear or control gear according to claim 1 , wherein the at least one second compartment is open-sided.

12. The switchgear or control gear according to claim 1 , wherein the at least one first compartment comprises at least one door or removable wall section.
