Chii chinonzi discharge?Nei midziyo yemagetsi ichida chidimbu chekuburitsa bvunzo?
Kuputsika kwechikamu chekubuda kwemagetsi mukuvharwa kwemidziyo yemagetsi, iyo inogona kuitika pedyo nemakondukita kana kumwewo, kunonzi kuburitsa chikamu.
Nekuda kwesimba diki padanho rekutanga rekubuda muchidimbu, kubuda kwayo hakukonzerese kuparara kwe insulation, uye iyo intact insulation pakati pe electrode isati yaburitswa inogona kuramba ichimira kushanda kwemagetsi emidziyo.Nekudaro, pasi peiyo yenguva refu yekushanda voltage, kukuvadzwa kwekudzivirira kunokonzerwa nekubuda kwechikamu kunoramba kuchikura, izvo zvinozotungamira mukuitika kwetsaona yekudzivirira.Kwenguva yakareba, high-voltage magetsi ekushandisa akashandisa asiri-voltage uye anomira voltage bvunzo kuti atarise mamiriro ekudzivirira uye kudzivirira kuitika kwetsaona yekupwanya.Kunyangwe idzo nzira dzekuyedza dziri pamusoro dzichigona kutonga muchidimbu kana zvakananga kuvimbika kwekudzivirira, hurema hunogona kuitika senge kuburitsa chikamu kwakakosha.Izvo zvakaoma kuwana, uye iyo insulation ichakuvadzwa panguva yekumira voltage test, kuderedza hupenyu hwebasa.
Maererano nenhamba dzenyika yangu pamusoro pekukuvadzwa kwevashanduri ve110KV uye pasi, 50% inokonzerwa nekukura zvishoma nezvishoma kwekubuda kwechikamu pasi pemagetsi ekushanda.Kuburikidza nekuyedzwa kwechikamu chekuburitsa, zvinokwanisika kuona kana paine chikamu chekubuda, kuomarara uye nzvimbo mukati memidziyo yekuvharira nenguva, uye kutora matanho akakodzera ekudzivirira matambudziko asati aitika.Mumakore achangopfuura, yakayerwa voltage yemidziyo yemagetsi iri kuwedzera.Kune hombe-yakakwirira-yakakwirira magetsi magetsi emidziyo, zvinokwanisika kutsiva iyo yenguva pfupi-yakakwirira-voltage inomira voltage bvunzo neyenguva yakareba chikamu chekuburitsa bvunzo.
Mitemo inoenderana inotaridza kuti yakakwira-voltage magetsi emagetsi anofanirwa kuyedzerwa kuburitswa zvishoma kana abva mufekitori, uye mushure mekuyedzwa kwemheni, zvichingodaro, bvunzo yekuburitsa chikamu inofanirwa kuitwa zvakare kuti ive nechokwadi chekuti kuburitswa kwemidziyo inosiya. fekitari iri mukati mechikamu chakakodzera.Munguva yekutariswa kwefekitori yetransformer muchitoro, zvechokwadi pakanga paine imwe nhamba yevashanduri vaisakwanisa kubva mufekitori nekuda kwekubuda kwakawandisa.
Mukuwedzera, panguva yekushanda kwemidziyo, nekuda kwezvikonzero zvakasiyana-siyana, kubudiswa kwekutanga kwechikamu kunogona kuve kwakakodzerwa, uye kunogona kukura zvishoma nezvishoma kuva kusina kukodzera, uye nzvimbo itsva dzekubudisa zvishoma dzinogona kugadzirwa.Naizvozvo, kuyerwa kwenguva dzose kwekubuda kwechikamu chemidziyo yekushandisa nechikamu chekushandisa ndiyo imwe yenzira dzakakosha dzekutarisa kwekudzivirira, uye zvakare iri nzira iri nani yekutonga kwenguva refu yakachengeteka kushanda kwekudzivirira.Kana paine kusagadzikana mumidziyo, senge chromatographic ongororo inodarika kukosha kwekutarisisa, zvinonyanya kukosha kuita chidimbu chekuburitsa bvunzo kuti uone nzvimbo isina kujairika uye dhigirii.
