The invention discloses a redundant direct current rod power supply device equally sharing power. A direct current rod power supply is composed of two sets of power supplies which are mutually redundant and standby, the two sets of power supplies can independently work and also can work at the same time, control is not needed when the two sets of power supplies work at the same time, automatic equal power sharing can be realized, a load can be equally distributed, and when one set of power supply breaks down, the broken-down power supply automatically exits and the other set of power supply bears all the load, so that concentrated and redundant power supply on a low frequency power supply cabinet is realized, and the system reliability is improved.
