Abstract
In a hybrid type gas insulation switch gear apparatus, a main enclosure including a first cylindrical section have a base and a second cylindrical section branched from the base. A bushing is mounted on the cylindrical section and including a hollow insulating housing having a housing space and a central conductor extended in the hollow insulating housing. A first insulating spacer is provided in the first cylindrical section and configured to separate the first hollow space into first and second segment spaces. An insulating enclosure is also mounted to the second cylindrical section and including an enclosure space. A second insulating spacer is provided between the insulating enclosure and the second cylindrical section and configured to separate the enclosure space from the second hollow space. A disconnecting switch is formed in the first segment space of the first cylindrical section and a circuit breaker is also formed in the insulating enclosure.
