2. The drop-out fuse is used for independently connecting the lead of the voltage transformer, and the method can meet the safety requirement of live working, but has the following four defects:
1. because the single-pole installation switch is adopted in part of the areas, the space is limited, the equipment is complex and various, and the installation of the equipment is not carried out in enough space.
2. The use of drop-out fuses has the hidden trouble of increasing operation, if any one of them looks fusion tube drops, can lead to the secondary side equipment of switch to lose operating power and voltage signal, and the switch can't normally use. In addition, the fuse falls and can cause PT (potential transformer) secondary signal mistake to think that the circuit lacks the looks, and superior circuit breaker exists the risk of malfunction, and PT (potential transformer) can't open phase operation for a long time. The operation staff can not use the operating rod to replace the fusion tube due to space limitation.
