Embodiment Construction
[0026] Below in conjunction with the accompanying drawings, the present invention will be further described by specific embodiments:
[0027] like figure 1As shown in the figure, the power supply system includes a power supply 1 and a three-phase line 2. There are several partition switches on the three-phase line 2, and a protection zone is formed between two adjacent partition switches. A differential protection system can be set on the partition switches. When a phase-to-phase short circuit occurs in the protection zone, the differential protection system controls the corresponding partition switch of the power inlet to trip to cut off the fault current. Several sectional switches can be set up in each protection zone. The sectional switches only need to have the ability to cut off the load current, and do not need to have the ability to cut off the short-circuit large current, so as to reduce the cost.
[0028] If the interphase short-circuit fault occurs at point F, the ...
