<p>PURPOSE:To simplify and miniaturize structure by housing a first disconnecting switch and a second disconnecting switch connected to the first terminal conductor section and second terminal conductor section of a circuit breaker respectively into a common tank, using the tank as a basic unit and forming first and second opening sections for connecting equipments. CONSTITUTION:Circuit breakers CB and first and second disconnecting switches DS1 and DS2 unified with the circuit breakers are housed into a tank 1 only by three phase sections. In each circuit breaker CB, interrupting sections including moving contacts and fixed contcts are housed into shells 3 with first and second terminal conductor sections 3b and 3c arranged at intervals in the axial direction of the insulating cylindrical sections 3 and insulating cylindrical sections 3a, and the fixed contacts and moving contacts are connected to the first terminal conductor sections 3b and the secand terminal conductor sections 3c respectively. First and second opening sections 6A and 6B for connecting equipments connected to the circuit breakers CB through both disconnecting switches are formed in positions corresponding to the first and second disconnecting switches DS1 and DS2 of the tank 1 respectively.</p> |
