Abstract

A circuit breaker is accommodated in a circuit breaker compartment such that a contacting/separating direction of a contact of the circuit breaker is along a vertical direction, a cable terminal of a first cable connected to one terminal of the circuit breaker via a first disconnector is accommodated in a first connection compartment such that a central conductor of the cable terminal is along the vertical direction, and a disconnector compartment which accommodates the first disconnector such that a contacting/separating direction of a contact of the first disconnector is along the vertical direction, is joined so as to be disposed between the circuit breaker compartment and the first connection compartment.

First claim

The invention claimed is:

1. A gas-insulated switchgear, wherein
a circuit breaker is accommodated in a circuit breaker compartment such that a contacting/separating direction of a contact of the circuit breaker is along a vertical direction,
a cable terminal of a first cable connected to one terminal of the circuit breaker is accommodated in a first connection compartment such that a central conductor of the cable terminal is along the vertical direction,
a cable terminal of a second cable connected to the other terminal of the circuit breaker directly or via a disconnector is accommodated in a second connection compartment such that a central conductor of the cable terminal is along the vertical direction,
insulation gas is sealed in each of the containers,
the first connection compartment and the second connection compartment are joined to the breaker container so as to be aligned horizontally in one direction or in opposite directions relative to the breaker container, and
a circuit breaker operating mechanism for switching the circuit breaker is disposed on an outer side, of the breaker container, in the contacting/separating direction of the contact.

2. A gas-insulated switchgear, wherein
a circuit breaker is accommodated in a breaker container such that a contacting/separating direction of a contact of the circuit breaker is along a vertical direction,
a cable terminal of a first cable connected to one terminal of the circuit breaker via a first disconnector is accommodated in a first connection compartment such that a central conductor of the cable terminal is along the vertical direction,
a cable terminal of a second cable connected to the other terminal of the circuit breaker directly or via a second disconnector is accommodated in a second connection compartment such that a central conductor of the cable terminal is along the vertical direction,
insulation gas is sealed in each of the containers,
the first connection compartment and the second connection compartment are joined to the breaker container so as to be aligned horizontally in one direction or in opposite directions relative to the breaker container, and
a circuit breaker operating mechanism for switching the circuit breaker is disposed on an outer side, of the breaker container, in the contacting/separating direction of the contact.

3. The gas-insulated switchgear according to claim 1 , wherein the cable terminal of the first cable and the cable terminal of the second cable are disposed so as to be oriented in opposite directions.

4. The gas-insulated switchgear according to claim 1 , wherein the cable terminal of the first cable and the cable terminal of the second cable are disposed so as to be oriented in a same direction.

5. The gas-insulated switchgear according to claim 2 , wherein
the first disconnector is accommodated in a disconnector compartment such that a contacting/separating direction of a contact of the first disconnector is along the vertical direction, and
the disconnector compartment has insulation gas sealed therein, and is joined so as to be disposed between the breaker container and the first connection compartment.

6. The gas-insulated switchgear according to claim 2 , wherein
the first disconnector is accommodated in the first connection compartment so as to be aligned with the cable terminal of the first cable in line such that a contacting/separating direction of a contact of the first disconnector is along the vertical direction, and
the first connection compartment is joined to the breaker container on a side opposite to a side on which the second connection compartment is joined to the circuit breaker compartment.

7. The gas-insulated switchgear according to claim 6 , wherein
the other terminal of the circuit breaker and the cable terminal of the second cable are connected to each other via the second disconnector, and
the second disconnector is accommodated in the second connection compartment so as to be aligned with the cable terminal of the second cable in line such that a contacting/separating direction of a contact of the second disconnector is along the vertical direction.

8. The gas-insulated switchgear according to claim 6 , wherein
an instrument transformer that is electrically connected to the other terminal of the circuit breaker is disposed on a side opposite to a side on which the second cable from the second connection compartment is led out.

9. The gas-insulated switchgear according to claim 6 , wherein
an arrester that is electrically connected to the other terminal of the circuit breaker is disposed on a side opposite to a side on which the second cable from the second connection compartment is led out.

10. The gas-insulated switchgear according to claim 1 , wherein
each of the containers includes divisional compartments into which each container is divided for each phase, and
a device to be accommodated in each container is divided for each phase so as to be accommodated in the respective divisional compartments.
