Kufunika kwa VLF kupirira voteji chipangizo kuti jenereta kupirira voteji mayeso

Pa ntchito katundu jenereta, kutchinjiriza pang'onopang'ono kuwonongeka pansi zochita za magetsi munda, kutentha ndi kugwedera makina kwa nthawi yaitali, kuphatikizapo kuwonongeka wonse ndi kuwonongeka pang'ono, chifukwa cha zolakwika.Kuyesa kwamagetsi kwa ma jenereta ndi njira yothandiza komanso yolunjika yodziwira mphamvu yotchinjiriza ya ma jenereta, ndipo ndizofunikira pamayeso odzitetezera.Chifukwa chake, kuyesa kwa Hipot ndi njira yofunikira yowonetsetsa kuti jenereta ikugwira ntchito bwino.

HV Hipot GDVLF Series 0.1Hz Programmable Ultra-low Frequency(VLF) High Voltage Generator

Njira yogwiritsira ntchito ma ultra-low frequency teststand voltage test kwa jenereta ndi yofanana ndi njira yopangira chingwe pamwambapa.M'munsimu ndi kufotokoza kowonjezera kwa malo osiyanasiyana.
1. Mayesowa amatha kuchitidwa panthawi yopereka, kukonzanso, kusintha pang'ono kwa ma windings ndi mayesero achizolowezi.Kuyesa kwamagetsi kwamagetsi a 0.1Hz kopitilira muyeso-otsika kumakhala kothandiza kwambiri pakuwonongeka kwa mapesi a jenereta kuposa ma frequency amagetsi kupirira mayeso amagetsi.Pansi pa mphamvu pafupipafupi voteji, popeza capacitive panopa ukuyenda kuchokera waya ndodo kuchititsa lalikulu voteji dontho pamene umayenda mu semiconductor odana ndi corona wosanjikiza kunja kutchinjiriza, voteji pa kutchinjiriza wa waya ndodo kumapeto yafupika;Pankhani ya ultra-low frequency, capacitor current imachepetsedwa kwambiri, ndipo kutsika kwa voteji pa semiconductor anti-corona wosanjikiza kumachepetsedwanso kwambiri, kotero kuti voteji kumapeto kwa kutchinjiriza ndipamwamba, zomwe zimakhala zosavuta kupeza zolakwika. pa
2. Njira yolumikizira: Mayeso amayenera kuchitidwa pang'onopang'ono, gawo loyesedwa limakhala lopanikizidwa, ndipo gawo lomwe silinayesedwe limafupikitsidwa mpaka pansi.​
3. Malinga ndi zofunikira za malamulo oyenerera, nsonga yapamwamba yamagetsi oyesera imatha kutsimikiziridwa motsatira njira iyi:

Umax=√2βKUo Mu chilinganizo, Umax: ndiye mtengo wapamwamba wa 0.1Hz test voltage (kV) K: nthawi zambiri imatenga 1.3 mpaka 1.5, nthawi zambiri imatenga 1.5

Uo: mtengo wovoteledwa wa jenereta yokhotakhota ya Voltage (kV)

β: Mphamvu yofanana ya 0.1Hz ndi 50Hz voliyumu, malinga ndi zofunikira za malamulo adziko lathu, tengani 1.2

Mwachitsanzo: kwa jenereta ndi voteji oveteredwa 13.8kV, mawerengedwe njira ya mayeso voteji pachimake mtengo wa kopitilira muyeso-otsika pafupipafupi ndi: Umax = √2× 1.2×1.5×13.8≈35.1(kV)
4. Nthawi yoyesera ikuchitika motsatira malamulo oyenerera
5. Pogwiritsa ntchito mphamvu zamagetsi, ngati palibe phokoso lachilendo, kununkhiza, utsi ndi kuwonetsera kosasunthika kwa deta, zikhoza kuganiziridwa kuti kusungunula kwalimbana ndi mayesero.Kuti mumvetse bwino momwe kutsekemera kumakhalira, malo a pamwamba pa kusungunula ayenera kuyang'aniridwa mozama momwe angathere, makamaka mayunitsi a mpweya wozizira.Zomwe zachitika zawonetsa kuti kuyang'anira mawonekedwe kumatha kupeza zochitika zachilendo zamtundu wa jenereta zomwe sizingawonekere ndi chida, monga ma corona, kutulutsa, ndi zina zambiri.
