<p>PURPOSE:To provide an easily-installed compact compound switch, by separably coupling a circuit breaker accommodated in a stationary insulator container to disconnecting switches accommodated in insulator tubes and providing penetrated current transformers around the bottoms of the insulator tubes. CONSTITUTION:The disconnecting switches 2A, 2B are accommodated in chambers 11, 21 defined in the insulator tubes 10, 20 thereby forming disconnecting switch units 10, 20. The circuit breaker 4 is, for example, a vacuum circuit breaker and is accommodated in the stationary insulator container 31 made of, for instance, epoxy resin, thereby forming a circuit breaker unit 30. The circuit breaker unit is separably coupled to the disconnecting switch units. The penetrated current transformers 3A, 3B are provided around the bottoms of the insulator tubes. Thereby, the dimensions are reduced. Thus, the easily-installed economical compound switch is formed.</p> |
