Small current neutral grounding system refers to isolated neutral or the three-phase system through arc suppression coil and high resistance grounding, when certain
When earth fault occurs for one phase, due to that cannot form short-circuit loop, earth-fault current is often smaller than load current more, so
This system is referred to as small current neutral grounding system.The criteria for classifying in China is：The system of X0/X1 ＞ 4~5 belongs to small current neutral grounding
System, wherein X0 are system zero-sequence reactance, and X1 is system forward-sequence reactance.The most common failure of small current neutral grounding system is single-phase connects
Ground, when singlephase earth fault occurs, every circuit for having capacitance over the ground will all have zero-sequence current by, due to zero-sequence current compared with
It is small, by the regulation of safe operation of power system code, can continue to run with 1~2 it is small when, but system non-faulting is relatively electric at this time
Pressure rise is line voltage, makes failure propagation if handling easily develop into line to line fault not in time, arc grounding can also cause complete set
System overvoltage, but since zero-sequence current is smaller, and have very big dispersiveness, investigating out ground path has certain difficulty, if system
In have arc suppression coil, difficult bigger.
Existing Small Electric Current Earthing And Routing Device cannot be managed concentratedly, cause administration fee to increase, enterprise
Use cost.
