The invention discloses an intensive phase-change switch. The intensive phase-change switch can be switched among the power generation state, the water pumping state and the switching-off state through movement of the first fixing part and the second fixing part in the box body, and the B-phase switch moving contact and the C-phase switch moving contact are both arranged on the second fixing part, so that when the second fixing part moves, the B-phase switch moving contact and the C-phase switch moving contact can be switched to the switching-off state. The B-phase switch moving contact and the C-phase switch moving contact can move along with the second fixing piece, and the possibility that one of the B-phase switch moving contact and the C-phase switch moving contact moves upwards and the other one moves downwards is avoided, so that the B-phase switch moving contact and the C-phase switch moving contact cannot move upwards and downwards. Compared with an existing three-phase intensive phase-change switch, the three-phase intensive phase-change switch is simple in structure, higher in transmission efficiency and better in reliability and stability, the V'wire outlet side terminal cannot be conducted with the V wire inlet side terminal and the W wire inlet side terminal at the same time, and the W 'wire outlet side terminal cannot be conducted with the V wire inlet side terminal and the W wire inlet side terminal at the same time, so that compared with the existing three-phase intensive phase-change switch, the three-phase intensive phase-change switch is simple in structure, higher in transmission efficiency and better in reliability and stability.
Description
technical field [0001] The invention relates to the field of pumped-storage power stations, in particular to an intensive type commutation switch. Background technique [0002] The commutation switch for pumped storage power station can be divided into two structural types according to the different ways of commutation, one is a three-phase five-pole independent type, and the other is a three-phase intensive type. These two types of commutation switches can be combined with other switches to form a complete set of pump-storage switchgear, but the overall structure of the two combinations is significantly different. With the construction and operation of more and more pumped-storage power stations in my country, the functional requirements of users for the complete switchgear are basically stable, and on the premise that the commutation switch meets the basic parameter requirements of pumped-storage power stations, users expect it to be more economical , simpler and more reli...
