MCB Tripping Curve

Cov khoom siv hluav taws xob me me (MCB) ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov circuits thiab cov khoom siv. Cov circuit breakers me me no yog tsim los txiav txim siab qhov ntws ntawm hluav taws xob thaum pom qhov txhaum, tiv thaiv kev puas tsuaj rau lub kaw lus thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Ib qho tseem ceeb ntawm MCB yog hom kab nkhaus, uas txiav txim siab lub sijhawm teb thiab qhov ntsuas tam sim no ntawm lub circuit breaker thaum nws mus ncig. Kev nkag siab txog ntau hom kab nkhaus yog qhov tseem ceeb rau kev xaiv MCB kom raug rau ib daim ntawv thov tshwj xeeb.

Tus kab tripping ntawm lub circuit breaker me me yog hais txog kev sib raug zoo ntawm lub magnetic tripping current thiab lub rated current. Muaj ntau yam trip curves, txhua tus haum rau ntau hom loads thiab daim ntawv thov. Cov hom trip curve feem ntau rau MCBs suav nrog Hom A, Hom B, Hom C thiab Hom D. Txhua hom muaj cov yam ntxwv tshwj xeeb thiab haum rau ntau qhov xwm txheej, los ntawm kev tiv thaiv semiconductor electronic circuits mus rau qhov chaw pib hnyav.

Hom A tripping nkhaus yog tus cwj pwm los ntawm lub zog sib nqus tripping ntawm (2-3) Hauv. Nws yog qhov tsim nyog rau kev tiv thaiv semiconductor hluav taws xob circuits, ntsuas circuits ntawm cov transformers fais fab qis, lossis cov kab ke nrog cov kab ntev thiab cov hluav taws xob me me. Hom A MCBs yog tsim los muab kev teb sai rau cov qhov tsis zoo qis, ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob rhiab heev thiab circuits uas xav tau kev tiv thaiv meej.

Lub zog hluav taws xob sib nqus ntawm hom B tripping curve yog (3-5) Hauv. Cov MCB no yog tsim rau cov khoom siv tiv taus thiab cov hluav taws xob tsawg. Lawv feem ntau siv rau hauv cov tshuab faib hluav taws xob hauv tsev, cov khoom siv hauv tsev thiab kev tiv thaiv kev nyab xeeb tus kheej. Hom B MCBs muab kev tiv thaiv zoo rau ntau yam kev siv hauv tsev thiab kev lag luam.

Lub zog hluav taws xob ntawm hom C tripping curve yog (5-10) Hauv. Cov MCB no yog qhov tsim nyog rau cov khoom siv inductive thiab cov teeb pom kev zoo siab. Lawv feem ntau siv los tiv thaiv cov kab faib khoom thiab cov teeb pom kev zoo nrog cov hluav taws xob conduction siab. Hom C MCBs yog ntau yam thiab tsim nyog rau kev siv hauv ntau yam lag luam uas xav tau kev tiv thaiv cov khoom siv inductive.

Hom D tripping nkhaus yog tus yam ntxwv los ntawm lub zog sib nqus tripping ntawm (10-20) Hauv. Cov MCBs no yog tsim rau cov kab ke nrog cov khoom thauj inductive siab thiab cov inrush currents loj. Lawv feem ntau siv los tiv thaiv cov khoom siv nrog cov inrush currents siab, xws li transformers thiab solenoid valves. Hom D MCBs yog tsim los tiv taus cov khoom hnyav thiab muab kev tiv thaiv txhim khu kev qha hauv cov chaw ua haujlwm.

Hauv kev xaus, kev nkag siab txog cov kab nkhaus ntawm ntau hom miniature circuit breakers yog qhov tseem ceeb rau kev xaiv MCB kom raug rau ib daim ntawv thov tshwj xeeb. Txawm hais tias tiv thaiv cov hluav taws xob rhiab heev lossis cov khoom siv hnyav hauv kev lag luam, MCBs nrog hom kab nkhaus mus ncig tsim nyog yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kab ke hluav taws xob. Nrog lawv cov peev xwm sib txawv, MCBs tseem yog ib feem tseem ceeb ntawm kev nyab xeeb hluav taws xob thiab kev tiv thaiv hauv ntau yam lag luam.

Mutai Group tau sau ntau tshaj kaum xyoo ntawm kev tsim khoom thiab kev muag khoom hauvcov khoom siv hluav taws xob, cov contactors, ob lub zogcov hloov pauv hloov pauv tsis siv neeg (ATS) thiab lwm yam kev lag luam cuam tshuam. Peb tos ntsoov yuav muaj lub sijhawm los ua haujlwm nrog koj.
