Kuyesa kwamphamvu kwa dielectric (kupirira voteji).

Kuyesa mphamvu yamagetsi, komwe kumadziwika kuti standstand voltage test, ndi muyeso wa kuthekera kwa kutsekereza kwamagetsi kupirira kuwonongeka chifukwa cha kuchuluka kwamagetsi.Ndi njira yodalirika yowunika ngati mankhwalawo ndi otetezeka kugwiritsa ntchito.

Pali mitundu iwiri yoyesera mphamvu yamagetsi: imodzi ndi DC yolimbana ndi kuyesa kwamagetsi, ndipo ina ndi AC mphamvu pafupipafupi kuyesa voteji.Zipangizo zamagetsi zapakhomo nthawi zambiri zimayesedwa ndi ma frequency a AC mphamvu yamagetsi.Magawo oyesedwa ndi ma voliyumu oyeserera a mayeso a mphamvu yamagetsi amafotokozedwa ndikufotokozedwa muyeso lililonse lazinthu.

Kodi cholinga choyezera kulimba kwa zida zamagetsi ndi chiyani?

Zinthu zomwe zimakhudza mtengo woyezera wa kukana kwa kutchinjiriza ndi: kutentha, chinyezi, voteji yoyezera ndi nthawi yochitapo kanthu, zotsalira zotsalira pakumangirira ndi momwe zimakhalira pamtunda, ndi zina zotero. kukwaniritsa:

a.Kumvetsetsa za insulating katundu wa nyumba zoteteza.Kapangidwe kabwino ka insulating (kapena insulating system) yopangidwa ndi zida zapamwamba zotchingira zimayenera kukhala ndi zida zabwino zotsekera komanso kukana kwambiri;

b.Kumvetsetsa mtundu wa chithandizo cha kutchinjiriza kwa zinthu zamagetsi.Ngati chithandizo cha kutchinjiriza kwa zinthu zamagetsi sichili bwino, ntchito yotchinjiriza idzachepetsedwa kwambiri;

c.Kumvetsetsa chinyontho ndi kuipitsidwa kwa chotchinga.Pamene kusungunula kwa zipangizo zamagetsi kumakhala konyowa komanso kuipitsidwa, kukana kwake kutsekemera kumatsika kwambiri;

d.Yang'anani ngati kusungunula kumapirira kuyesa kwa voltage.Ngati kupirira kuyesedwa kwa magetsi kumachitidwa pamene kukana kwazitsulo zamagetsi kumakhala kochepa kuposa malire ena, kuyesa kwakukulu kumapangidwa, zomwe zimabweretsa kuwonongeka kwa kutentha ndi kuwonongeka kwa zipangizo zamagetsi.Chifukwa chake, miyeso yosiyanasiyana yoyeserera nthawi zambiri imanena kuti kukana kwa insulation kuyenera kuyesedwa musanayambe kuyezetsa magetsi.

Dielectric mphamvu (kupirira voteji) tester:

RK267 mndandanda, RK7100, RK9910, RK9920 mndandanda kupirira voteji (mphamvu dielectric) testers zigwirizane GB4706.1, malinga ndi gulu panopa anawagawa m'magulu AC limodzi ndi AC ndi DC wapawiri cholinga magulu awiri, malinga ndi linanena bungwe voteji osiyanasiyana m'gulu. monga 0-15kV kupirira voteji tester Ndipo mitundu iwiri ya voteji wapamwamba kwambiri kupirira voteji testers pamwamba 20kV.Mphamvu yotulutsa mphamvu ndi 0-100kV, ndipo mphamvu yotulutsa pakali pano imatha kufika 500mA.Chonde tchulani malo ogulitsa zinthu zina.

Zofunikira zotsutsana ndi zida zapakhomo sizokwera, ndipo 5kV imatha kukwaniritsa zofunikira zoyezetsa magetsi pazida zambiri zapakhomo.Mtengo wa RK2670AM, RK2671AM/BM/CM RK2671DMndi mtundu wamakono (AC ndi DC 10KV, 100ma yamakono),RK2672AM/BM/CM/DM/E/EM,RK2674A/B/C/-50/-100ndi mitundu ina ya kupirira ma voltage tester.

Pakati pawo RK267 ndikusintha pamanja,Mtengo wa RK71, RK99mndandanda amatha kuzindikira zokha, ntchito yolumikizirana.
