Transformer nruab nrab point grounding kuj txee

Nyob rau hauv 6-35KV AC zog daim phiaj ntawm kuv lub teb chaws lub hwj chim system, muaj ungrounded nruab nrab cov ntsiab lus, grounded los ntawm arc suppression coils, high-resistance grounded, thiab me me-kuj grounded.Nyob rau hauv lub hwj chim system (tshwj xeeb tshaj yog lub nroog network fais fab mov system nrog cables raws li lub ntsiab kis tau tus mob kab), lub hauv av capacitive tam sim no loj, uas yuav ua rau qhov tshwm sim ntawm "intermittent" arc av overvoltage muaj tej yam kev mob "tseem ceeb", ua rau arcing. Daim ntawv thov ntawm qhov nruab nrab taw tes tiv thaiv grounding txoj kev rau tiam ntawm grounding overvoltage tsim ib tug tso tawm channel rau lub zog (them) nyob rau hauv daim phiaj-rau-hauv av capacitance, thiab injects resistive tam sim no rau hauv qhov txhaum point, ua rau lub grounding txhaum tam sim no coj mus rau hauv tus account. qhov tsis kam-capacitance xwm, txo thiab Theem lub kaum sab nraud qhov sib txawv ntawm qhov hluav taws xob txo qhov rov ua hluav taws xob tom qab tam sim no ntawm qhov chaw txhaum hla xoom thiab ua rau qhov "tseem ceeb" ntawm lub arc overvoltage, kom lub overvoltage txwv tsis pub dhau 2.6 lub sij hawm ntawm theem voltage, thiab nyob rau tib lub sij hawm guarantees high-rhiab heev hauv av txhaum kev tiv thaiv Cov khoom raug txiav txim thiab txiav tawm lub thawj thiab thib ob faults ntawm lub feeder, yog li zoo tiv thaiv cov kev ua haujlwm ntawm lub cev.
