Three phase switchgear or control gear

1. A switchgear, comprising:

at least one first compartment, being configured to be arc proof and comprising:

a second compartment that is a cable connection compartment; and

a third compartment;

a fourth 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 main busbar system,

a three position linear or rotational movement disconnector, and

a circuit breaker;

a cable connection, the cable connection housed in the second compartment, and the circuit breaker and the three position linear or rotational movement disconnector are mounted vertically one above the other in the third compartment; and

a plurality of auxiliary switchgear or control gear components, the plurality of auxiliary switchgear or control gear components comprising a disconnector drive and a circuit breaker drive, the disconnector drive and the circuit breaker drive being mounted vertically one above the other in the fourth compartment;

wherein an interior door is located in a wall segregating the second compartment from the third compartment, wherein the switchgear is configured such that the interior door must be in position to provide an arc proof segregation between the second compartment and the third compartment for a user to be able to at least partially enter the second compartment when any components, including the three position linear or rotational movement disconnector and the circuit breaker, in the third compartment are energized, and wherein the interior door is configured to operate automatically,

wherein the second compartment has an exterior door or removal wall section in an exterior wall of the second compartment,

wherein the interior door located in the wall segregating the second compartment from the third compartment closes automatically when the exterior door or removable wall section in the exterior wall of the second compartment is open.

2. The switchgear according to claim 1 , wherein, when the plurality of main switchgear or control gear components are de-energized, the at least one first compartment is configured to enable the user to access an interior of the at least one first compartment.

3. The switchgear according to claim 1 , wherein a voltage sensor and a current sensor are housed in the second compartment.

4. The switchgear according to claim 1 , wherein:

at least one sensor is located in the second compartment, and

the at least one sensor is configured to monitor components, including the cable connection, in the second compartment.

5. The switchgear according to claim 1 , wherein:

at least one sensor is located in the third compartment, and

the at least one sensor is configured to monitor the components in the third compartment.

6. The switchgear according to claim 1 , wherein the fourth compartment is open-sided on at least one side.

7. The switchgear according to claim 1 , wherein the third compartment has at least another door or removal wall section in an exterior wall of the third compartment.

8. The switchgear according to claim 1 , wherein the third compartment is sized such that the user can gain access to the interior of the third compartment without being able to completely enter the third compartment.

9. The switchgear according to claim 1 , wherein:

at least one sensor is located in the fourth compartment, and

the at least one sensor is configured to monitor components, including the disconnector drive and the circuit breaker drive, in the fourth compartment.

10. The switchgear according to claim 1 , wherein one or more of the plurality of auxiliary switchgear or control components are housed in a removable module within the fourth compartment.
