PROBLEM TO BE SOLVED: To provide a switch gear which enables the user to perform pull operation safely and to perform maintenance and inspection easily. SOLUTION: It becomes possible to pull out a DC high-speed breaker truck unit 3, a commutator circuit truck unit 5, and a commutation capacitor truck unit 6 separately by mounting a DC high-speed breaker, a commutator circuit, and a commutation capacitor individually on separate truck units 3, 5, and 6, and also, mounting the commutator circuit truck unit 5 and the commutation capacitor truck unit 6 on one axial flow device fixing frame 4. Thus, the pullout operation becomes easy, and besides the maintenance and inspection can be performed in a short time. COPYRIGHT: (C)2003,JPO
