HYXHX akatevedzana akangwara arc kudzvinyirira mudziyo
rondedzero yechigadzirwa
Kuti ugadzirise dambudziko renguva refu re overvoltage ye arc grounding, vazhinji vavo vakashandisa kuisa arc suppression coils panzvimbo yakarerekera kutsiva capacitive ikozvino kudzvinyirira mukana we arc kuitika pane kukanganisa.Zviripachena, chinangwa cheiyi nzira ndechekubvisa iyo arc, asi nekuda kweakawanda maitiro eiyo arc kudzvanya coil pachayo, zvakaoma kubhadhara zvinobudirira iyo capacitive ikozvino, kunyanya kukuvadzwa kunokonzerwa neiyo yakakwira frequency chikamu kune magetsi ekushandisa. haigoni kukurirwa.Pahwaro hweiyo arc kudzvinyirira coil, kambani yedu yakagadzira YXHX yakangwara arc kudzvinyirira mudziyo.
kushanda musimboti
● Kana iyo system iri kushanda zvakajairika, iyo microcomputer controller ZK yechishandiso inoramba ichiona chiratidzo chemagetsi chinopiwa nevoltage transformer PT.
● Kana iyo yakavhurika triangle voltage U yevoltage transformer PT yekubatsira yechipiri inotendeuka kubva kune yakaderera kugona kune yakakwirira, inoratidza kuti sisitimu yakashata.Panguva ino, microcomputer controller ZK inotanga pakarepo, uye panguva imwe chete maererano nePT yechipiri inobuda masaini Ua, Ub, Uc Shanduko kutonga rudzi rwekukanganisa uye mutsauko wechikamu:
A. Kana iri single-phase PT disconnection fault, iyo microcomputer controller ZK icharatidza mutsauko wechikamu uye chiratidzo chekudzima chekukanganisa kwekudzima, uye inoburitsa passive switch yekubata chiratidzo panguva imwe chete.
B. Kana iri simbi pasi kukanganisa, microcomputer controller ZK acharatidza chikamu musiyano uye pasi hunhu chiratidzo chepasi chikanganiso, uye panguva imwe chete kubuda passive chinja kuonana chiratidzo.Inogonawo kutumira murairo wekuvhara wekuita kune vacuum contactor JZ mukhabhineti maererano nezvinodiwa zvemushandisi., inogona kudzikisa zvakanyanya iyo yekusangana voltage uye nhanho voltage, izvo zvinoita kuti uve nechokwadi chekuchengetedzwa kwemunhu.
C. Kana iri arc ground kukanganisa, microcomputer controller ZK inoratidzira pasi kukanganisa chikamu musiyano uye pasi hunhu zviratidzo, uye panguva imwechete inotumira murairo wekuvhara kune vacuum contactor JZ yechikamu chekukanganisa kuti ishandure zvakananga arc pasi kupinda. ivhu resimbi, uye pasi arc inokonzerwa neviri The arc voltage pamagumo inokurumidza kuderedzwa kusvika zero, uye chiedza chearc chinodzima zvachose.Kana gidhi remagetsi rinonyanya kuve nemitsara yekumusoro, iyo vacuum contactor JZ yemuchina inongovhura mushure memasekondi mashanu.Kana iri kukanganisa kwenguva pfupi, iyo system inodzokera kune yakajairika.Kana iri kukanganisa zvachose, ichashanda zvakare kugadzirisa zvachose overvoltage.Basa uye zvinobuda passive switch yekubata chiratidzo
D. Kana mudziyo wacho wakashongedzerwa otomatiki mutsara wekusarudza basa, apo yechipiri yakavhurika katatu voltage U yevoltage transformer PT inobatsira kubva pakuderera kusvika kune yakakwira, iyo diki ikozvino yekugadzika mutsara yekusarudza module pakarepo inoita data pa zero-sequence ikozvino. yemutsara wega wega Kana pasina imwe-chikamu chepasi chikanganiso, ichadzokera kune yakajairika;kana pane simbi yepasi inokanganisa, mutsara wekukanganisa uchasarudzwa maererano neamplitude ye zero-sequence current yemutsara.Kuunganidzwa kwedata kunoitwa pane zero-sequence ikozvino yemutsara, uye mutsara wakashata unosarudzwa zvinoenderana nemusimboti wekuti shanduko yehuwandu hwemutsara unokanganisa ndiyo yakakura pamberi uye mushure mekunge arc yekudzika yadzimwa.
Zvimwe zvekushandisa
● Ichi chishandiso chinogona kuve chakagadzirirwa otomatiki mutsara wekusarudza basa zvinoenderana nemushandisi zvinodiwa.
● Iyo HYLX diki ikozvino yekugadzika mutsara yekusarudza mudziyo wakagadzirwa nekambani yedu inonyanya kusarudza mutsara maererano neamplitude ye zero-sequence ikozvino yemutsetse kana sisitimu iri simbi yakadzika, uye inosarudza mutsara unonyanya zvichienderana nekungoerekana kwachinja zero. -kutevedzana ikozvino kwemutsara pamberi uye shure kwechigadziro chinoshanda kana sisitimu yakadzikwa nearc light.Iyo inokunda kukanganisa kweiyo yakajairwa mutsara wekusarudza mudziyo, sekunonoka kusarudzwa kwemutsara kumhanya uye yakaderera mutsara kusarudzwa kwechokwadi kana arc yakadzikwa.
● Ichi chishandiso chinogona kunge chakashongedzerwa nebasa rekubvisa (kubvisa) resonance (vibration) zvinoenderana nezvinodiwa nemushandisi.
●Chishandiso ichi chinogona kuve neyakagadzirirwa anti-saturation voltage transformer yakagadziridzwa nekambani yedu uye yekutanga-yezvino-inomisa resonance eliminator, iyo inoparadza zvakanyanya mamiriro eferromagnetic resonance uye inodzivirira "kupisa PT" uye Kana "kuputika PT inishuwarenzi" tsaona;inogona zvakare kuve yakashongedzerwa neiyo microcomputer resonance yekubvisa mudziyo kubvisa ferromagnetic resonance zvinoenderana nezvinodiwa nemushandisi.
chigadzirwa muenzaniso
chiyero chekushandisa
● Ichi chigadzirwa chakakodzera 3 ~ 35kV medium voltage power system;
Chishandiso chakakodzera masisitimu emagetsi apo nzvimbo isina kwayakarerekera haina kudzika pasi, iyo isina kwayakarerekera poindi inodzika kuburikidza nearc kudzvanya coil, kana iyo isina kwayakarerekera poindi inodzika kuburikidza nekupikisa kwepamusoro;
● Ichi chigadziri chinokodzera magetsi emagetsi anotungamirirwa netambo dzetambo, akavhenganiswa magetsi emagetsi emagetsi uye mitsara yepamusoro, uye magetsi emagetsi anotungamirirwa nemitsetse yepamusoro.

Features
Apo chigadziro chiri kushanda zvakajairika, chine basa rekuisa chitunha mubhabhineti;panguva imwecheteyo, ine basa rekugadzirisa alarm alarm uye kuvhara;iyo system metal ground fault alarm, basa rekufambisa iyo system ground fault point;basa rekubvisa arc light grounding uye system resonance;low voltage uye overvoltage alarm function;uye basa rekurekodha ruzivo senge fault alarm yekubvisa nguva, kukanganisa hunhu, kukanganisa chikamu musiyano, system voltage, kuvhura matatu-yemahara voltage, uye pasi capacitance ikozvino, iri nyore pakubata kukanganisa uye kuongororwa.
● Kana imwe-chikamu chepasi chikanganiso chikaitika muhurongwa, chigadziro chinogona kudzikisa zvakananga chikamu chinokanganisa kuburikidza nechikamu chakakosha-kuparadzanisa vacuum contactor inenge 30mS.Kana iyo arc yakadzimwa, iyo arc ichadzimwa pakarepo, uye iyo arc ivhu overvoltage ichadzikamisa iyo online voltage level, iyo inogona kunyatso dzivirira The phase-to-phase short circuit inokonzerwa ne-single-phase grounding uye arrester kuputika njodzi inokonzerwa arc grounding overvoltage;kana iri simbi inogadzika, inogona kuderedza zvakanyanya iyo yekusangana voltage uye nhanho voltage, iyo inobatsira pakuchengetedza kuchengetedzwa kwemunhu (simbi ivhu inogona kusetwa zvinoenderana nezvinodiwa nemushandisi) chiito);kana ikashandiswa mugedhi remagetsi inotongwa nemitsara yekumusoro, iyo vacuum contactor inovhura otomatiki mushure mekunge mudziyo washanda kwemasekonzi mashanu.Kana iri kukanganisa kwenguva pfupi, iyo system inodzokera kune yakajairika.Deredza kukanganisa kwe overvoltage.
● Kana kukanganisa kwehurongwa kunoitika, chigadziro chicharatidza chikamu chekukanganiswa kwekukanganisa uye kubuda kwezviratidzo zvekubatana panguva imwe chete, kuitira kuti mushandisi akwanise kuvharira chigadziro chekudzivirira chinogona kukonzera kusashanda nekuda kwekubviswa.
●Tekinoroji yemuchina ye "intelligent switch (PTK)" inogona kudzivirira kuitika kwe ferromagnetic resonance, uye kudzivirira zvine mutsindo kubva mutsaona dzakaita sekutsva uye kuputika kunokonzerwa nesystem resonance.
● Mudziyo une RS485 interface uye unotora yakajairwa MODBUS yekutaurirana protocol kuti ive nechokwadi chekuti mudziyo unopindirana nehurongwa hwese hwekutarisa uye kuona kutapurirana kwedata uye mabasa ekushandisa kure.
