Munguva yekushanda kwejenareta, kusungirirwa kunozoderera zvishoma nezvishoma pasi pekuita kwemunda wemagetsi, tembiricha uye mechanical vibration kwenguva yakareba, kusanganisira kuparara kwese uye kuderera kwechikamu, zvichikonzera kukanganisa.Iyo inomira voltage bvunzo yejenareta inzira inoshanda uye yakatwasuka yekuona simba rekudzivirira remajenareta, uye chinhu chakakosha chemukati mebvunzo dzekudzivirira.Naizvozvo, Hipot bvunzo zvakare inzira yakakosha yekuona kushanda kwakachengeteka kwejenareta.
HV Hipot GDVLF Series 0.1Hz Programmable Ultra-low Frequency(VLF) High Voltage Generator
Nzira yekushanda ye-ultra-low frequency standstand voltage test yejenareta yakafanana nenzira yekushanda yetambo iri pamusoro.Inotevera itsanangudzo yekuwedzera yenzvimbo dzakasiyana.
1. Muedzo uyu unogona kuitwa panguva yekuendesa, kuwedzeredza, kutsiva zvishoma kwema windings uye bvunzo dzenguva dzose.Iyo yekumira voltage bvunzo yemota ine 0.1Hz yekupedzisira-yakaderera frequency inoshanda zvakanyanya pakukanganisa kwekudzivirira kweiyo jenareta kupera kupfuura simba frequency inomira voltage test.Pasi pemagetsi emagetsi emagetsi, sezvo iyo capacitive ikozvino inoyerera ichibva kune waya tsvimbo inokonzera kudonha kukuru kwemagetsi painoyerera nepakati pe semiconductor anti-corona layer kunze kwekuvharirwa, iyo voltage pakuvharwa kwetambo yetambo pamagumo inoderedzwa;Panyaya ye-ultra-low frequency, iyo capacitor ikozvino yakadzikira zvakanyanya, uye kudonha kwevoltage pane semiconductor anti-corona layer zvakare yakaderedzwa zvakanyanya, saka voltage pamagumo ekudzivirira akakwira, izvo zviri nyore kuwana zvirema. .
2. Nzira yekubatanidza: Muedzo unofanirwa kuitwa muzvikamu, chikamu chakaedzwa chinomanikidzwa, uye chikamu chisina kuedzwa chipfupi-chinotenderedzwa pasi.
3. Zvinoenderana nezvinodiwa nemirairo yakakodzera, kukosha kwepamusoro kweiyo test voltage inogona kutariswa zvinoenderana neinotevera fomula:
Umax=√2βKUo Muforomo, Umax: ndiyo yepamusoro kukosha kwe0.1Hz test voltage (kV) K: kazhinji inotora 1.3 kusvika 1.5, kazhinji inotora 1.5
Uo: kukosha kwakatarwa kwejenareta stator inopeta Voltage (kV)
β: Yakaenzana coefficient ye0.1Hz uye 50Hz voltage, zvinoenderana nezvinodiwa nemirairo yenyika yedu, tora 1.2
Semuenzaniso: kune jenareta ine rated voltage ye13.8kV, nzira yekuverenga yetest voltage peak value ye-ultra-low frequency is: Umax = √2 × 1.2 × 1.5 × 13.8≈35.1 (kV)
4. Nguva yekuedza inoitwa maererano nemitemo yakakodzera
5. Muchigadziro chekumira magetsi, kana pasina ruzha rusina kujairika, kunhuwa, utsi uye kusagadzikana kwedata kuratidza, zvinogona kutorwa sekuti kuvharidzira kwakadzivirira muedzo wekuedzwa.Kuti unzwisise zviri nani mamiriro ekudzivirira, nzvimbo yepamusoro yekudzivirira inofanira kutariswa zvakakwana sezvinobvira, kunyanya kumhepo inotonhorera.Chiitiko chakaratidza kuti kutarisa kwechitarisiko kunogona kuwana zvisina kujairika jenareta insulation phenomena isingagone kuratidzwa nechiridzwa, senge yepasi corona, kubuda, nezvimwe.
