The invention discloses a direct-current power supply system, which is characterized in that: a pair of fuses of each group of output branch is sequentially arranged up and down in the same plane to replace the left and right arrangement mode of the conventional direct-current power supply system, an output layout that anodes are uniformly in the upper row and cathodes are uniformly in the lower row or the cathodes are uniformly in the upper row and the anodes are uniformly in the lower row is formed, and the anodes and the cathodes of the upper and lower rows are covered by adopting a single insulating plate, so equal potential areas of positive and negative voltages are respectively formed, the space of the anode or cathode operating area is increased, the safety of wiring is further increased, short circuit of the anode and the cathode of a single output branch can be prevented, and normal operation of equipment and personnel safety of installation and maintenance personnel are ensured.
Description
technical field [0001] The invention relates to a power supply system, in particular to a direct current power supply system. Background technique [0002] The DC power supply system is widely used, and it is an important part of the normal operation of electrical equipment. Such as figure 1 As shown, the DC power supply wiring method widely used at present is that the two fuses 10a, 11a (10b, 11b; 10c, 11c; 10d, 11d) in each group of output branches a (group b, c, d) are in the same The planes are placed side by side on the left and right, the left positive and the right negative, the positive and negative poles are placed on the same row, and the distance between the positive and negative poles is very close. The normal operation of electrical equipment may even endanger the personal safety of installation operators; in addition, an insulating plate 12a (12b, 12c, 12d) is arranged between the two fuses of each group of output branches, and the circuit structure is compli...
