Abstract Because the inner-bridge connection substation saves a breaker and a isolator, the cost and area is reduced, and becomes the first choice when building the substation in the city and its surroundings. The secondary voltage and current circuit of inner-bridge substation are different from two-section single bus substation, it should be paid particular attention to design. The BZT ( standby power supply automatic swiching) applies in the inner-bridge substation is changed too. In this paper, the existing problems in design about voltage loop, current circuit and BZT of inner-bridge substation are improved.
