Umthengi waseGuangdong uthengela ibhetshi yePD- Izixhobo zovavanyo zasimahla kwi-HV HIPOT

Kutshanje, abathengi baseFoshan, eGuangdong bathenge ibhetshi ye-GDYT yothotho lwe-PD-Simahla yovavanyo lweSeti kwi-HV HIPOT.Ngentsebenziswano esebenzayo yabalingane bokuvelisa kwiworkshop, kwaye ngokomhla wokunikezelwa kwekhontrakthi, ibhetshi yezixhobo zokuvavanya iye yahlolwa kwaye yathunyelwa kakuhle.

Iseti ye-GDYT yovavanyo lwePD-Simahla iseti isetyenziswa ikakhulu kuvavanyo lwamandla ombane wokumelana novavanyo lweziguquli, iziguquli zamandla, izaphuli zesekethe ezinevoltage ephezulu, i-capacitors yokudibanisa, ii-capacitor bushings, iiswitshi, njl. .Inqanaba le-insulation lixhomekeke kumbane wefrikhwensi yamandla.Ngexesha elifanayo, umlinganiselo wokukhupha inxalenye yeemveliso ezingentla nawo unokuqhutywa.

ukwakheka kwemveliso:

• Amandla amatyeli okumelana nesixhobo sovavanyo lombane: ukulawula imveliso yombane ophakamileyo ochaziweyo we-transformer ngaphandle kovavanyo lokukhupha,
• Umtshina wokukhupha inxalenye: Hlalutya kwaye ukhangele i-pulse yokukhupha eyenziwa yimveliso yokuvavanya, bonisa i-pulse waveform ngeendlela ezahlukeneyo zokuhlalutya;
• Akukho siguquli sovavanyo lokukhuphela ngokungaphelelanga: I-non-partial discharge test transformer ibonelela ngokuzinzile konikezelo lwamandla aphezulu ombane kuyo yonke isethi yezixhobo zovavanyo.
• Isixhobo sokuzihlukanisa kunye nokucoca: Umbane ophezulu we-voltage obonelelwa ngumguquli wokuvavanya uguqulwa ube ngumbane ococekileyo ophezulu we-voltage ngokusebenzisa ukuhlukaniswa kunye nesixhobo sokucoca;
• Ngaphandle kokukhutshwa kwenxalenye yokudibanisa i-capacitor: Fumana isignali ye-pulse kwisiphaluka esiphezulu sombane kwaye ubone ukukhutshwa kwenxalenye yemveliso evavanyiweyo ngesixhobo sokukhupha inxalenye;
• Ukumelana nokukhuselwa: khusela izixhobo zokuvavanya amandla aphezulu kunye nemveliso evavanyiweyo;

Iimbonakalo:

• Kuphuhliswe ngempumelelo i-cylinder ye-epoxy insulating ye-non-partial discharge kunye nenani elincinci lokukhupha inxalenye.
• Umbane we-impedance uphantsi, ongcono kunomgangatho wesizwe.
• Ukusebenzisa iteknoloji yokulawula ngokuzenzekelayo, inezinga eliphezulu lokuzenzekelayo kunye nekhono elinamandla lokuchasana nokuphazamiseka.
• Ukusebenzisa isixhobo sokukhusela sombane esikhawulezayo, ukuthembeka okuphezulu.

I-HV HIPOT iphumelele iindumiso ezivela kubathengi "ngoyilo lwemveliso olunengqiqo, umgangatho ozinzileyo nothembekileyo, umgangatho ophezulu kunye nenkonzo efike ngexesha", umgangatho obalaseleyo wemveliso, kunye nenkonzo egqibeleleyo emva kokuthengisa.Ixhasa umgaqo womthengi kuqala kwaye igxininisa ekudaleni iimvavanyo zokuthintela amandla aphezulu kwishishini lokulinganisa umbane.Umenzi wezixhobo.
