Ts'ebetsong ea ho sebetsa mochine o se nang mojaro, ho tla ba le ntho e ke keng ea qojoa ea 'mele, ke hore, ho khaola.Bothata ba ts'ebetso ea overvoltage ka lebaka la ho khaoha ha sekhechana sa potoloho bo ka thibeloa ka ho nka mehato e latelang:
1. Ntlafatsa motheo oa tšepe
Ho ntlafatsa motheo oa tšepe ho na le phello e itseng ea ho fokotsa hona joale ha ho na mojaro.Hobane hona joale magnetizing hona joale le tšepe tahlehelo hona joale hammoho theha ha ho mojaro hona joale, 'me magnetizing hona joale tla hlahisa matla a khoheli,' me tšepe mantlha tahlehelo tla etsa hore ho lahleheloa ke tšepe hona joale, kahoo tšepe ea mantlha ea transformer ke ntlha ea bohlokoa ea ho. fokotsa ho se be le moroalo hona joale.Ho tsoela pele ho ntlafatsa sebopeho sa mantlha le ho ntlafatsa boleng ba tšepe ea tšepe ke mehato e 'meli ea motheo.Lijo-thollo tse batang li ka sebelisoa sebakeng sa lishiti tsa tšepe tsa silicon, hobane sistimi ea matla a khoheli ea lithollo tse kolobisitsoeng ka serame e batla e phahame.Ha transformer e fetoloa, mokokotlo oa tšepe o tlameha ho hlahlojoa le ho hlahlojoa ka thata ho latela litekanyetso tsa boleng bo nepahetseng.
2. Maqhubu a amohela mofuta o tangled
HV HIPOT GDB-P e fetolelang karo-karolelano ea motlakase
Transformer ea 220kV ke transfoma ea mantlha.Haeba mokhoa o ts'oanelang o tsitsitse, matla a parasitic a transformer a tla eketseha.The ferekaneng matsoelintsoeke ke ho kenya thinya e 'ngoe ea matsoelintsoeke ka ho toba pakeng tsa motlakase haufi le thinya, e le hore capacitance longitudinal ea matsoelintsoeke e eketseha,' me ka sebele phapang e ka bang teng pakeng tsa thinya e haufi e tla eketseha ka ho eketsehileng, e le hore boteng ba In ketsahalo. ka lebaka la overvoltage phenomenon, motlakase oa pele o ka ajoa ka ho lekana har'a li-turning.
3. Sebelisa sesebelisoa se nang le sehanyetsi se tšoanang
Motsotsong oa ho khaoha ha hajoale, matla a khoheli ho inductor a tla fetoloa matla a motlakase ho tjhaja capacitor.Ka nako ena, haeba sesebelisoa se hokahane ka tsela e ts'oanang le sehanyetsi, matla a khoheli a ka har'a inductor a ka lokolloa.Ka mor'a hore sesebelisoa se nang le ho hanyetsa ka mokhoa o ts'oanang se koaloe pele ho khaoha ha hona joale, phetoho e ts'oanang ea ho hanyetsa e khutšoanyane.Ka mor'a ho khaola ha hona joale, sesebelisoa se tšoasa R84Th N resistor ho etsa hona joale, e le hore matla a khoheli a matla a motlakase ho inductor a sebelisoe.
