Transformer kwazvakarerekera point grounding resistance cabinet

Tsanangudzo Pfupi

Muiyo 6-35KV AC magetsi gidhi yesimba renyika yangu, kune nzvimbo dzisina kwazvakarerekera, dzakavakirwa kuburikidza nearc kudzvanya macoil, yakakwirira-kupokana yakadzika, uye kushoma-kupokana kwakadzika.Musimba remagetsi (kunyanya iyo yemaguta network magetsi ekupa system ine tambo semitsetse yekufambisa), pasi capacitive ikozvino yakakura, iyo inogona kuita kuti kuitika kwe "intermittent" arc pasi overvoltage ine chaiyo "yakakosha" mamiriro, zvichikonzera arcing. Iko kushandiswa kweiyo isina kwayakarerekera point resistance yekumisa nzira yekugadzirwa kwepasi overvoltage inoumba chiteshi chekuburitsa chesimba (chaji) mugidhi-kusvika-pasi capacitance, uye inobaya inopikisa ikozvino munzvimbo yekukanganisa, zvichiita kuti chikanganiso chepasi chitore. a resistance-capacitance nature, kuderedza uye The phase angle musiyano wevoltage inoderedza re-ignition rate mushure mekunge ikozvino pamhosva yadarika zero uye inotyora "critical" condition of the arc overvoltage, kuitira kuti overvoltage ishoma mukati me2.6 nguva dzechikamu chemagetsi, uye panguva imwechete inovimbisa yakakwirira-sensitivity pasi kuchengetedzwa kwekukanganisa Midziyo yacho inonyatso sarudza uye inocheka zvikanganiso zvekutanga uye zvechipiri zveanodyisa, nekudaro zvinodzivirira zvinobudirira kushanda kwakajairika kwehurongwa.
