Yakagadzirirwa Thermal Overload Relay Factory

CDADA, mugadziri uye mutengesi anobva kuChina, anopa huwandu hwakawanda hwemagetsi emagetsi emagetsi, kusanganisira thermal overload relays. Yedu tekinoroji timu inopa yakazara OEM kugadzirisa masevhisi uye mushure mekutengesa tekinoroji rutsigiro. Tinotambira kubvunza kwenyu.

Chii chinonzi Thermal Overload Relay?

A Thermal Overload Relay mudziyo wekudzivirira wakagadzirirwa kudzima mota yemagetsi kana ichikwevera yakawandisa ikozvino kwenguva yakareba, zvichiita kuti iwedzere kupisa. Kusiyana nefuse kana muyerocircuit breakeriyo inopindirana neinopopopo high current (maseketi mapfupi), TOR inoshandisa inverse-time character. Izvi zvinoreva kuti nguva yekufamba inodzikira sezvo yazvino ichiwedzera, inonyatso girazi rekupisa kwemota windings.

Mhedzisiro yetekinoroji yedu inotsamira pane bimetallic strip musimboti: masimbi maviri ane macoefficients akasiyana ekuwedzera kwekupisa akabatanidzwa pamwechete. Kana yapiswa nemotor current, strip inokotama. Kana iyo yazvino ikadarika iyo yakachengeteka kugadzika kwenguva yakati, tambo inokotama zvakakwana kuti ifambise maitirwo ekubatsira, kucheka simba kune mota yekutanga coil.

Mhando uye Zvikamu

Kugona kwedu kugadzira kunosanganisira huwandu hwakazara hwematekinoroji ekudzivirira, akagadzirirwa zvakasiyana siyana zvemaindasitiri.

Type	Key Features	Typical Application
Bimetallic Relay	Kudziya kwakananga kana kusiri kwakananga kuburikidza nemakoiri ekudziya. Yakasimba, yakapfava, uye inodhura-inoshanda.	General chinangwa chekudzivirira mota (pombi, mafeni, conveyors).
Electronic Relay	Solid-state, hapana zvikamu zvinofamba. Inoratidzira chaiyo yekunzwa ikozvino, chikamu-kurasikirwa kuona, uye kuchengetedzwa kwepasi.	Maitiro akakosha, yakakwirira-inertia mitoro, uye nharaunda dzine njodzi.

Core Mabasa uye Intelligent Dziviriro

Yedu Thermal Overload Relays haingori nyore switch; ivo vachengeti vakangwara vemota.

● Overload Protection: Basa rekutanga. Nekubatanidza yazvino nekufamba kwenguva ( I2tI2t ), iyo relay inodzivirira insulation yemota kubva mukudzikira. Iyo inobvumira kwechinguvana inrush currents (kutanga mota) pasina kunetseka kutsika asi inopindura zvine mutsindo kune yakaremerwa yakawandisa.

● Pase Failure Protection (Single Phasing): Muchikamu chezvikamu zvitatu, kana chikamu chimwe kikarasika, mota inokweva yakawandisa pane zvikamu zviviri zvasara kuchengetedza torque. Marelay edu ane muchina wakasiyana (kana kuti electronic sensing) unoona kusaenzana uku obva afamba ipapo ipapo, zvichiita kuti mota isatsva.

● Kuripira Tembiricha: Chinhu chakakosha chenzvimbo dzemaindasitiri. Marelay edu ane inoripira bimetallic strip inopesana nekuchinja kwetembiricha. Izvi zvinoita kuti nzvimbo yerwendo irambe yakarurama zvisinei kuti mapaneru ari mudura rinotonhora kana kuti pauriri hwefekitari inopisa (-20°C kusvika +60°C).

Rwendo Kirasi Sarudzo

Isu tinogadzira marelay anoenderana neakajairwa makirasi erwendo:

◆ Kirasi yechigumi

◆ Kirasi 10A/20: Yakajairwa kumainjiniya eruzhinji.

◆ Kirasi 30: Pakuremerwa kwepamusoro-soro (semuenzaniso, mafeni makuru, macentrifuges) anotora nguva yakareba kuti atange.

◆ Mashandisirwo Ekutanga uye Nyaya dzeKushandisa

◆ Industrial Manufacturing: Kudzivirira mabhandi ekutakurisa zvinhu, maoko emurobhoti, uye maspindle emuchina weCNC kuti asajame kana kuwandisa.

◆ HVAC Systems: Kuchengetedza mafeni mahombe ecentrifugal nemacompressor motors muzvivakwa zvekutengesa.

◆ Kuchenesa Mvura: Zvakakosha kudzivirira pombi dzinopinda mumvura uye maeerators kubva pakuoma kana kuvharika.

◆ OEM Michina: Yakabatanidzwa muzvigadziro zvemichina yekurongedza, machira, uye michina yekugadzira chikafu.

Precision Manufacturing

Yedu yekugadzira maitiro ndeye masterclass mune thermal engineering uye mechaniki chaiyo.

1. Main Raw Materials:

◆ Bimetallic Strips: Mwoyo wemudziyo. Isu tinoshandisa alloys epamusoro-giredhi (semuenzaniso, Nickel-Iron/Manganese-Mhangura) ane macoefficient ekuwedzera akaverengerwa kuti tive nechokwadi chekukotama kunoenderana tembiricha.

◆ Heater Elements: Precision-wound resistance wire (Nichrome) kana kuti heavy-duty copper bars inogadzira kupisa kunoenzanirana neskweya yezvino ( I2RI2R ).

◆ Contacts: Silver-Nickel (AgNi) kana Silver-Cadmium-Oxide (AgCdO) yevabatsiri (NC/NO), tichiona kusaina kwakavimbika kuPLC kana kuti contactor.

◆ Zvimba: High-simba,-flame-retardant Polyamide (PA66) kana Bakelite, yakagadzirirwa kushingirira kushushikana kwekushisa kwakanyanya.

2. Kugadzira & Kugadzirisa Mafambiro Ekushanda:

◆ Component Fabrication: Kudhinda chaiko kwebimetallic strips nemacoil eheta.

◆ Kugadzirisa: Nhanho yakakosha zvikuru. Iyo relay inopfuudzwa nepamusoro-ikozvino calibration tunnel. Technicians gadzirisa "current setting dial" kuti iite zvemakanika pre-stress the bimetallic strip, kuona kuti inofamba neamperage chaiyo (semuenzaniso, 10A, 16A).

◆ Assembly: Bimetallic strip, hita, and trip mechanism (kusanganisira lever inosiyanisa yekudzivirira kurasikirwa) zvakabatanidzwa ne microscopic tolerances.

◆ Potting (Optional): Panzvimbo dzakaoma, muchina wemukati wakavharirwa muepoxy resin kudzivirira kukoromoka uye kukuvadzwa kwekudengenyeka.

◆ Rigorous Quality Control and Testing Standards

Tinotevedzera IEC/EN 60947-4-1 uye GB/T 14048.4 zviyero. Yedu yemhando yekuvimbisa mapuroteni akagadzirirwa kuti ive nechokwadi chekuti relay inotevedzera iyo mota yekudziya curve zvakakwana.

Zviyero Zvokuedzwa uye Fekitari Yekuongorora Maitiro:

Test Item	Standard Reference	Yedu Factory Standard & Method
Trip Kirasi Verification	Inosimbisa nguva-yazvino curve.	Yakaedzwa pa 7.2 x Yakayerwa Zvazvino. Kirasi 10 inofanira kufamba mu <10s; Kirasi 20 mu <20s.
Cold State Calibration	Inosimbisa chokwadi kubva pakatanga kutonhora.	Yazvino yakasimudzwa ku 1.05 x Setting. HAUfanire kufamba mu <2 maawa. Zvino yasimudzwa ku 1.2 x Setting. Inofanirwa kufamba mu <2 maawa.
Phase Kukundikana Test	Inosimbisa kuchengetedzwa kwechikamu chimwe chete.	Imwe nhanho yazvino yakaiswa ku0, imwe payakayerwa ikozvino. Relay inofanira kufamba mukati menguva yakatarwa (semuenzaniso, <2 mins).
Ambient Temp Compensation	Inosimbisa kugadzikana mukupisa/kutonhora.	Yakaedzwa mukamuri yemamiriro ekunze pa -20°C uye +60°C. Musiyano wenzvimbo yerwendo unofanirwa kuva < ±5%.
Mechanical Life	Inosimbisa kusimba.	1,000 kusvika 10,000 macycles ekuseta patsva nemafambisirwo erwendo pasina kutadza kushanda.

Kugona Kwedu Kwekugadzira

Nzvimbo yedu yakashongedzerwa kubata iyo yakatetepa fizikisi yekupisa manejimendi.

◆ Production Line: Tinoshandisa semi-automated assembly lines zvakanyatsogadzirirwa kuti tikwanise kubata bimetallic strips zvinonzwisa tsitsi, kudzivirira mechanical stress inogona kushandura kupisa kwawo.

Advanced Equipment:

◆ High-Current Calibration Bench: Inokwanisa kubaya majekiseni anosvika 1000A kutevedzera kuremerwa uye kuona nguva dzerwendo nemamillisecond nemazvo.

◆ Environmental Climate Chambers: Inoshandiswa kuyedza kutembiricha muripo wetembiricha pane yakazara tembiricha yeindasitiri.

◆ Laser Welding Stations: Nekugadzira kubatanidza kwakasimba, kushoma-resistant pakati pezvinhu zvinodziya nematerminals.

Nyanzvi Chikwata:

◆ Thermal Engineers: Nyanzvi mukufambisa kupisa nesayenzi yezvinhu vanogadzira bimetallic geometry.

◆ Calibration Technician: Vashandi vane hunyanzvi hwepamusoro vanokwenenzvera nzira dzerwendo kuti vaone kuti relay yega yega inosangana nezvinodiwa zveKirasi 10A/20/30.

◆ Quality Assurance: Yakazvipira kuongorora "trip curve" kuenderana kudzivirira dambudziko ririkuitika mumunda.

Sarudza yedu Thermal Overload Relays. Hatingogadziri zvinhu; isu tinogadzira kuvimbika kunoita kuti mota dzako dzirambe dzichimhanya uye mitsetse yako yekugadzira ichifamba.
