Musiyano Pakati peHigh Voltage Load Switch uye High Voltage Circuit Breaker

Switch yemagetsi ane simba guru imhando yebasa riri pakati pe "high voltage circuit breaker" ne "high voltage isolation switch", "high voltage load switch" ne "high voltage fuse" zvinowanzo shandiswa mu "series"; Inoshandiswa kudzora ma "power transformers". "High voltage load switch" ine mudziyo uri nyore wekudzimisa "arc extinguishing", saka inogona kudzima "load current" uye overload current. Zvisinei, haigone kubvisa "short circuit current", saka inowanzo shandiswa mu "series" ne "high voltage fuse", ne "fuse" yekudzivirira "short circuit".

Switch yemagetsi ane simba guru imhando yebasa riri pakati pe "high voltage circuit breaker" ne "high voltage isolation switch", "high voltage load switch" ne "high voltage fuse" zvinowanzo shandiswa mu "series"; Inoshandiswa kudzora ma "power transformers". "High voltage load switch" ine mudziyo uri nyore wekudzimisa "arc extinguishing", saka inogona kudzima "load current" uye overload current. Zvisinei, haigone kubvisa "short circuit current", saka inowanzo shandiswa mu "series" ne "high voltage fuse", ne "fuse" yekudzivirira "short circuit".

Circuit breaker zvinoreva mudziyo wekuchinja unogona kudzima, kutakura nekudzima magetsi pasi pemamiriro enguva dzose edunhu uye kudzima, kutakura nekudzima magetsi pasi pemamiriro enguva isina kujairika edunhu mukati menguva yakatarwa. Macircuit breaker akakamurwa kuita macircuit breaker ane voltage yepamusoro uye macircuit breaker ane voltage yakaderera zvichienderana nekushandiswa kwawo. Kupatsanurwa kwemiganhu yemagetsi epamusoro nemagetsi akaderera hakuna kujeka. Kazhinji, ayo ari pamusoro pe3kV anonzi michina yemagetsi epamusoro.

Mabasa akasiyana:

Switch ine simba guru yakakodzera sisitimu yemagetsi yeAC 10KV, 50HZ, kana ine seti yakazara yemidziyo yekuparadzira uye switchgear yenetwork yeringi, nzvimbo dzakasanganiswa uye zvimwe zvinoshandiswa, zvinoshandiswa zvakanyanya mumapurojekiti ekuvaka nekushandura network, mabhizinesi emaindasitiri nekuchera migodhi, zvivakwa zvepamusoro nenzvimbo dzeveruzhinji, inogona kushandiswa se ring network yemagetsi kana terminal, inotamba basa rekugovera simba, kudzora nekudzivirira. Ine mabhenefiti ehukuru hwekutyoka, yakachengeteka uye yakavimbika, inogara kwenguva refu yemagetsi, inoshanda kakawanda, chimiro chakamanikana, saizi diki, huremu hwakareruka, uye hapana chikonzero chekugadzirisa. Ne off rated current, overload current. Inogona kutyora short circuit current uye kudzivirira michina kuti isashande pasina phase. Switch ine fracture iri pachena. Yakashongedzerwa ne grounding switch electric spring mechanism ine kugona kuvhara, iyo inogona kudzorwa kure nekure.

Macircuit breaker anogona kushandiswa kuparadzira simba remagetsi, kutanga mamota asingashande kakawanda, kuchengetedza tambo dzemagetsi nemamota, uye kudzima circuit otomatiki kana paine zvikanganiso zvakakura zve overload, short circuit uye undervoltage. Mabasa avo akafanana nekubatanidzwa kwe fusing switch uye over and under thermal relay. Uye kazhinji hapana chikonzero chekuchinja zvikamu mushure mekuputsa fault current. Parizvino, yave ichishandiswa zvakanyanya.
