Sei iyo AC Resonant Test System ichigadzira overvoltage?

Iyo yakakura iyo capacitance yechigadzirwa chakaedzwa uye kudonha kwekuita kweiyo test transformer, kunowedzera kujeka kwecapacitance kusimuka.Naizvozvo, kana isu tichiita iyo AC inomira voltage bvunzo yeakateedzana resonance yakakura-capacity test chinhu, inodiwa kuyera zvakananga voltage pakupera kwechinhu chekuyedza kudzivirira chinhu chekuyedza kuti chisave pasi pemhepo yakawandisa.

HV Hipot GDTF-800kVA/400kV AC Resonant Test System

Iyo overvoltage phenomenon yeakateedzana resonance test mudziyo inokonzerwa nezvinhu zvinotevera:

(1) Mhepo yekutanga inomanikidzwa kamwe kamwe pachinzvimbo chekuwedzera zvishoma nezvishoma kubva ku zero voltage.
(2) Kana pachine voltage yakakwira, kamwe-kamwe cheka magetsi, pane kudonha zvakaenzana kusvika pazero wobva wadzima voltage.Iyo inogona kuoneka kubva kushanduko yekushandura mhepo inotenderera kuti mamiriro maviri ari pamusoro apa achaita kuti overvoltage pachigadzirwa chakaedzwa, chisingabvumirwe.

Kune (1) kuvharirwa nedunhu rekutonga kudzivirira iyo isiri-zero voltage kubva pakumanikidzwa kungoerekana yamanikidzwa.
Kune (2) iyo nzira yekushanda yakakodzera inofanira kuitwa zvakasimba kudzivirira.
(3) Chinyorwa chebvunzo chinoputsika kamwe kamwe.Izvi zvinowanzosangana uye zvisingadzivisiki.Kana iyo yekubuda kweiyo bvunzo transformer yakabatana zvakananga kune yakaedzwa chigadzirwa, kana iyo yakaedzwa chigadzirwa ichidonha kamwe kamwe, mukana wekubuda kweiyo bvunzo transformer inokurumidza kumanikidzwa kusvika zero, izvo zvakaenzana nekamwe kamwe chiito pakubuda. kuguma kwekuedza transformer-imwe wave mberi yakanyanyisa kukwira Kukosha kwepamusoro kwemhepo yemhepo inoputika yakaenzana nekukosha kwepakarepo kweiyo pakarepo test voltage yechinhu chekuedza, asi polarity inopesana.Izvi zvinogadzira njodzi yakawandisa pane iyo longitudinal insulation yeyeyedzo transformer windings.

Nzira yekudzivirira ndeyekubatanidza inodzivirira inodzivirira ine yakakosha yekudzivirira kukosha munhevedzano pakati peiyo transformer inobuda magumo emagetsi frequency series resonance test device uye chinhu chekuedza, kuitira kuti impulse voltage yepolarity yakatarisana iite panhevedzano yedunhu. iyo inodzivirira resistor uye transformer inlet capacitance.Kwenguva pfupi yenguva, yakawanda yemagetsi inodonha pane inodzivirira kudzivirira.
