Residual Current Circuit Breaker Factory Direct Price

CDADAyakavambwa muna 2004, kunyangwe matangiro edu akadzokera kuma1980s. Tichitora pamakumi emakore ehunyanzvi hunyanzvi, isu takashanduka kuita mugadziri akakura uye nyanzvi uye mutengesi weResidual Current Circuit Breakers. Tinokukoka iwe kuti ubatsirwe nesu kuti ubatsirwe kubva kune yakavimbika tekinoroji yekutsigira masevhisi uye yakananga-kubva-kufekitari mitengo.

Chii chinonzi Residual Current Circuit Breaker (RCCB)?

Imwe RCCB mudziyo wekuchengetedza magetsi wakagadzirirwa kubvisa sekiti pose painoona kusaenzana kuri pakati pemakondukita anogara (phase) nemanautral. Kusaenzana uku, kunozivikanwa se residual current kana leakage current, kunoratidza kuti magetsi arikuyerera nenzira yaasingatarisiri—zvichida nomumuviri womunhu kana kuti kupera simba.

Kusiyana neMCBkanaMCCB, RCCB haipapi zvakawandisa kana kudzivirira kwepfupi-sekete payoga (kunze kwekunge zvasanganiswa nazvo muRCBO). Chinangwa chayo chete ndechekuchengetedza hupenyu uye kudzivirira moto. Inoshanda zvichibva pa Kirchhoff's Current Law, apo huwandu hwemagetsi anopinda pajunction hunofanira kuenzana nehuwandu hwemhepo inobuda pairi. Kana ma "in" uye "out" currents akasiyana nekupfuura kunzwisiswa kwemudziyo (semuenzaniso, 30mA), RCCB inofamba.

Mhando uye Zvikamu

Yedu yekugadzira portfolio inovhara mhando dzakasiyana dzeRCCB kuti dzienderane nenzvimbo dzakasiyana dzemagetsi, kubva kudzimba dzechikamu chimwe kusvika kune dzakaoma-nhatu-chikamu maindasitiri grids.

Type	Mapango / Configuration	Key Features	Typical Application
Type AC	2-Banga (1P+N) / 4-Pti (3P+N)	Inoona sinusoidal AC yakasara mafungu.	General pekugara uye yekutengesa magetsi / magetsi maseketi.
Type A	2-Pole / 4-Pole	Inoona AC uye pulsating DC yakasara mafungu.	Masekete ane mitoro yemagetsi (washing machine, makomputa, dimmers).
Type F	2-Pole / 4-Pole	Inoona AC, pulsating DC, uye composite multi-frequency currents.	Specialized maseketi ane anosiyana kumhanya madhiraivha (VSD) uye Kirasi I midziyo.
Type B	4-Bango	Inoona ese Type A/F mafungu uye akatsetseka eDC asara mafungu.	Matatu-chikamu EV ekuchaja zviteshi, solar inverters, uye michina yekurapa.

Core Mabasa uye Intelligent Dziviriro

Mwoyo weRCCB yedu ndeye Zero-Sequence Current Transformer (Toroid). Ichi chikamu chinoramba chichitarisa iyo magnetic field inogadzirwa nekuyerera kwazvino.

Leakage Detection: Mumamiriro ezvinhu akajairika, magineti eLive and Neutral currents anodzima imwe neimwe. Kana nzira yekudonha kuvhu ichiitika (semuenzaniso, munhu anobata waya mhenyu), chiyero chinoputsika.

Rapid Disconnection: Transformer inoona iyi "residual" flux uye inoita kuti magetsi apinde mumhepo yechipiri. Iyi siginecha inokwidziridzwa (mumhando dzemagetsi) kana kuti inobata zvakananga relay inonzwika (mumhando dzemagetsi emagetsi), zvichiita kuti mechanical latch isunungure uye ivhure zvinobatika.

Sensitivity Ratings:

High Sensitivity (10mA - 30mA): Nekuda kuchengetedzwa kwakanangana nevanhu (kuchengetedzwa kwevanhu). Zvinosungirwa kudzimba dzekugezera, zvigadziko, uye matunhu ekunze.

Kunzwa zviri pakati nepakati (100mA - 300mA): Zvekudzivirira kudhumhana uye kudzivirira moto. Inoshandiswa mumabhodhi makuru ekugovera kuchengetedza tambo kubva pakukanganisa kwekudzivirira.

Yekutanga Zvikumbiro uye Nyaya dzekushandisa

Kuchengetedzwa Kwekugara: Kuiswa kunosungirwa mudzimba dzekugezera, makicheni, uye kunze kwekunze kudzivirira kuvhunduka kubva kumidziyo yakaita semaomesa ebvudzi kana maturusi emagetsi.

Industrial Machinery: Kudzivirira vashandisi kubva kumagetsi kuvhunduka kana uchibata simbi-cased midziyo kana inotakurika maturusi.

Healthcare Facilities: Kuve nechokwadi chekuchengetedzeka kwevarwere muzvipatara umo kunyangwe madiki ekudonha mafungu anogona kuuraya (uchishandisa Type B kana nyanzvi yekurapa IT masisitimu).

Renewable Energy: Kuchengetedza DC uye AC mativi e solar PV masisitimu uye EV yekuchaja zviteshi kubva kuzvikanganiso zvepasi.

Precision Manufacturing: Kubva Raw Material kusvika Kupedzwa Chigadzirwa

Yedu yekugadzira maitiro ndeye symphony yechokwadi magineti uye mechanic engineering.

1. Main Raw Materials:

Zero-Sequence Transformer Core: Made from high-permeability Permalloy (Nickel-Iron alloy) kana Nanocrystalline strips. Ichi chinyorwa chakakosha pakuona maminetsi ekudonha mafungu pasina saturation.

Rwendo Relay/Solenoid: A very sensitive polarized relay inoshandura siginecha yemagetsi kubva patransformer kuita machanicha kufamba.

Housing: Plame-retardant Polycarbonate (PC) kana Nylon (PA66), yakagadzirwa kuti isabatike uye isingachinji.

Contacts: Silver-Cadmium-Oxide (AgCdO) kana Silver-Nickel (AgNi) yekuchinja kwakavimbika uye kushomeka.

2. Kugadzira & Kugadzirisa Mafambiro Ekushanda:

Sravana Sameeralu Serial 4th Sravana Sameeralu Serial 4th Toroid Winding: Iyo precision transformer core yakakuvadzwa nezviuru zvemajana e Ultra-fine copper wire. Izvi zvinofanirwa kuitwa nekuchenjerera zvakanyanya kudzivirira kupfupisa majana.

Core Encapsulation: Magineti core yakavharirwa muepoxy resin kuti ichengetedze kubva pakuzunguzika uye kunyorova, zvichiita kuti igare yakamira kwenguva refu.

Assembly: Toroid inoiswa yakatenderedza nzira yekondakita (kana kuti makondukita anopfuura nayo). Iyo nzira yekufamba yakabatanidzwa kune hombe yekubata latch.

Calibration (Sensitivity Setting): Iri ndiro danho rinokosha zvikuru. Isu tinoshandisa chaiyo yazvino masosi kuisa jekiseni rekudonha (semuenzaniso, 30mA). Iyo coil yerwendo inogadziridzwa zvine mutsindo kudzamara yanyatsoita pachikumbaridzo.

Yakasimba Hunhu Kudzora uye Kuedza Mayero

Tinotevedzera IEC/EN 62423 uye IEC/EN 61008 zviyero. Kuedza kwedu kwakagadzirwa kuti tive nechokwadi chokuti mudziyo unoshanya chete pazvinofanira, uye nguva dzose pazvinenge zvichiita.

Zviyero Zvokuedzwa uye Fekitari Yekuongorora Maitiro:

Test Item	Standard Reference	Yedu Factory Standard & Method
Rwendo Current Test	Inosimbisa kunzwa (IΔn).	Jekiseni zvazvino pa 1.0 x IΔn (inofanira rwendo <300ms) uye 0.5 x IΔn (haifanire kufamba).
Nguva Kunonoka Muedzo	Inosimbisa kumhanya kwekushanda.	Jekiseni 5 x IΔn (e.g., 150mA). Mudziyo unofanirwa kupinda mu < 40ms (General Type) kana mukati menguva yakatarwa yeRudzi S (Selective).
Dielectric Simba	Inosimbisa kuparadzaniswa.	Yakaiswa 2000V AC kweminiti 1 pakati pemapopu/pokuburitsa materminals nefuremu. Hapana kuparara.
Mechanical Operation	Inosimbisa kusimba kwe latch.	2,000 macycles e ON/OFF operation pasina kukundikana.
Short-Circuit Withstand	Inosimbisa kugona kwekupona.	RCCB inofanira kumira neshort-circuit current (e.g., 3kA kana 6kA) pasina kuputika kana kubata moto (yakasimbiswa nefuse protection).

Yedu Yekugadzira Kugona: Mutsetse, Zvishandiso, uye Chikwata

Nzvimbo yedu yakashongedzerwa kubata hutete hwemagineti inonzwa zvikamu.

Production Line: Tinoshandisa automated toroidal winding machines anoita kuti maturn count arambe achichinja, zvinova zvakakosha pakuziva kwazvino.

Advanced Equipment:

Precision Leakage Yazvino Calibrators: Zvishandiso zvine hunyanzvi zvinokwanisa kugadzira mvura inovhuvhuta ine resolution ye0.1mA yekunyatsogadzirisa rwendo.

Magnetic Shielding Chambers: Inoshandiswa panguva yekubatanidza kudzivirira magineti ekunze kuti asakanganise magadzirirwo anonzwisa tsitsi.

Automatic Test Mabhenji: 100% yemayunitsi anoedzwa rwendo rusati rwapakurwa.

Nyanzvi Chikwata:

Magnetic Engineers: Nyanzvi mukugadzira geometry ye transformer ye zero-sequence kuti iwedzere kunzwisiswa.

Calibration Technicians: Vashandi vakadzidziswa zvikuru vanomboona masikirwo erwendo emhando dzakasimba.

Hunhu Hwakanaka: Yakazvipira kuongorora maitiro ekukundikana uye kuona kuvimbika kwenzira yerwendo.

Sarudza yedu Yasara Yazvino Circuit Breakers. Hatingogadziri masiwichi; isu mainjiniya rugare rwepfungwa runobva pakuziva dunhu rako riri kutarisa musana wako.
