Three phase switchgear using single phase equipment in single casing

A three phase switchgear or control gear, comprising:

• a first compartment;
• a second compartment;
• a third compartment;
• a first plurality of components for a first phase;
• a second plurality of components for a second phase;
• and
• a third plurality of components for a third phase;
• wherein, each of the first, second, and third pluralities of components comprises a main busbar, a three position linear or rotational movement disconnector switch, a single phase circuit breaker pole, a circuit breaker single phase actuator and a cable connection;
• wherein for the first phase, the second phase, and the third phase, the main busbar, the three position linear or rotational movement disconnector switch, and the single phase circuit breaker pole are housed in the first compartment;
• wherein the cable connection for each of the first phase, the second phase, and the third phase is housed in the second compartment;
• wherein the second compartment comprises a first door or removable wall section, and wherein the switchgear or control gear is configured such that an operator can gain access to an inside of the second compartment via the first door or removable wall section whilst the switchgear or control gear is in operation;
• and
• wherein the circuit breaker single phase actuator for each of the first phase, the second phase, and the third phase is housed in the third compartment;
• wherein the third compartment comprises a second door or removable wall section, and wherein the switchgear or control gear is configured such that the operator can gain access to an inside of the third compartment via the second door or removable wall section whilst the switchgear or control gear is in operation;
• wherein the second compartment is separated from the first compartment by a first arc proof segregation;
• and
• wherein the third compartment is separated from the first compartment by a second arc proof segregation.
