Abstract

The invention provides an emergency power supply device for a nuclear power plant. The emergency power supply device comprises a plurality of switchboards and a plurality of cables with joints; the input end of each switchboard is connected into one diesel generating set; a bolt hole for connecting a cable is formed in the internal bus-bar of each switchboard; one cable is laid between every two switchboards in the plurality of switchboards; and the joints of the cables correspond to the positions of the bolt holes in the internal bus-bars of the switchboards. With the emergency power supply device of the invention adopted, power supply reliability is improved, design cost is reduced, and operation difficulty is controlled.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to an emergency power supply device for a nuclear power plant. Background technique [0002] Currently in the field of nuclear power, the generator set includes two diesel generator sets, one as a working unit and the other as a standby unit. Each diesel generator set is connected to a switchboard, one diesel generator set works normally, and the adjacent diesel generator set is used as a backup power supply. The corresponding specific execution process is as follows: when the diesel generator set corresponding to one of the two adjacent switchboards fails and the switchboard loses power, it is necessary to take the key from the key cabinet in the duty chief room to open the power-off switchboard cabinet. Push in the movable switch in the cabinet of the power-off switchboard, use the key to open the safety baffle of the trolley switch of the power-off switchboard, connect the...
