Customized Thermal Overload Relay Factory

CDADA, cov chaw tsim khoom thiab cov chaw muag khoom nyob rau hauv Suav teb, muaj ntau yam khoom siv hluav taws xob tsawg, suav nrog thermal overload relays. Peb pab neeg ua haujlwm muab kev pabcuam OEM customization nrog rau kev pabcuam tomqab muag. Peb txais tos koj cov lus nug.

Dab tsi yog Thermal Overload Relay?

Lub Thermal Overload Relay yog ib qho khoom siv tiv thaiv uas tsim los hloov hluav taws xob lub cev muaj zog thaum nws nqus tam sim no ntau dhau rau lub sijhawm ntev, ua rau nws kub dhau. Tsis zoo li lub fuse lossis tus qauvCircuit Court breakeruas cuam tshuam rau tam sim no siab tam sim no (short circuits), TOR siv tus yam ntxwv hloov pauv lub sijhawm. Qhov no txhais tau tias lub sij hawm tripping txo qis raws li qhov tam sim no nce, zoo kawg nkaus mirroring lub peev xwm ntawm lub cev muaj zog windings.

Lub hauv paus ntawm peb cov thev naus laus zis tso siab rau lub hauv paus ntsiab lus bimetallic strip: ob hlau nrog sib txawv coefficients ntawm thermal expansion bonded ua ke. Thaum rhuab los ntawm lub cev muaj zog tam sim no, lub sawb khoov. Yog tias qhov tam sim no tshaj qhov chaw nyab xeeb rau lub sijhawm tshwj xeeb, lub sawb khoov kom txaus rau cov neeg siv khoom sib txuas, txiav lub zog rau lub tshuab hluav taws xob pib lub kauj.

Hom thiab Classifications

Peb lub peev xwm tsim khoom suav nrog tag nrho cov spectrum ntawm overload tiv thaiv technologies, tailored rau ntau yam kev xav tau kev lag luam.

Hom	Cov yam ntxwv tseem ceeb	Daim ntawv thov
Bimetallic Relay	Direct lossis indirect cua sov ntawm cov cua sov coils. Robust, yooj yim, thiab nqi-zoo.	Lub hom phiaj dav dav tiv thaiv lub cev muaj zog (twj, kiv cua, conveyors).
Electronic Relay	Solid-state, tsis muaj qhov txav. Nta tam sim no sensing, theem-tsis pom, thiab kev tiv thaiv hauv av.	Cov txheej txheem tseem ceeb, siab-inertia loads, thiab ib puag ncig txaus ntshai.
Solid State (SSR)	Siv tam sim no transformers thiab microprocessors. Zero txij nkawm, teb ceev heev.	High-performance servo motors thiab precision machinery.
Manual/Auto Reset	Phau ntawv: Yuav tsum muaj kev cuam tshuam tus neeg teb xov tooj kom rov pib dua (kev nyab xeeb). Auto: Resets cia li tom qab txias (tsis muaj neeg saib xyuas).	Phau Ntawv Qhia: Lub tshuab uas tsis xav txog rov pib dua yog qhov txaus ntshai. Nws pib: HVAC, twj tso kua mis nyob rau hauv tej thaj chaw deb.

Core Functions thiab Intelligent Protection

Peb Thermal Overload Relays tsis yog cov keyboards yooj yim xwb; lawv yog cov neeg txawj ntse saib xyuas lub cev muaj zog.

● Kev Tiv Thaiv Tshaj Tawm: Lub luag haujlwm tseem ceeb. Los ntawm kev sib koom ua ke tam sim no dhau lub sijhawm (I2tI2t), tus relay tiv thaiv lub cev muaj zog los ntawm thermal degradation. Nws tso cai rau ib ntus inrush tam sim no (pib lub cev muaj zog) yam tsis muaj kev cuam tshuam tsis zoo tab sis reacts decisively rau sustained overloads.

● Phase Failure Protection (Ib Phasing): Nyob rau hauv peb-theem system, yog tias ib theem poob lawm, lub cev muaj zog rub ntau dhau tam sim no ntawm ob theem ntxiv kom tswj tau lub zog. Peb cov relays muaj cov txheej txheem sib txawv (lossis kev ntsuas hluav taws xob) uas kuaj pom qhov tsis sib xws thiab mus ncig tam sim ntawd, tiv thaiv lub cev tsis muaj zog.

● Kev them nyiaj kub: Ib qho tseem ceeb rau kev lag luam ib puag ncig. Peb cov relays tau nruab nrog ib qho nyiaj npib bimetallic strips uas tiv thaiv qhov cuam tshuam ntawm qhov kub thiab txias hloov pauv. Qhov no ua kom paub tseeb tias qhov chaw mus txawv tebchaws tseem muaj tseeb txawm tias lub vaj huam sib luag nyob hauv lub tsev khaws khoom khov lossis lub chaw ua haujlwm kub (-20 ° C txog + 60 ° C).
