Ụkpụrụ na mmepụta nke nnyonye anya eletrọnịkị EMI

Tupu anyị akọwa ụkpụrụ nke nnyonye anya electromagnetic, anyị ghọtara ugbu a ihe kpatara EMI:

1. Ihe na-akpata EMI

Ụdị nnyonye anya elektrọn dị iche iche bụ isi ihe na-emetụta ndakọrịta nke akụrụngwa eletrọnịkị.Ya mere, ịghọta ihe kpatara nnyonye anya elektrọnik bụ ihe dị mkpa dị mkpa maka igbochi nnyonye anya elektrọn yana kwalite ndakọrịta elektrọnik nke ngwaahịa eletrọnịkị.Enwere ike kewaa ọgbọ nke nnyonye anya electromagnetic na:

nnyonye anya ime Ntụbiaka n'etiti ngwa eletrọnịkị dị n'ime

1) Ike ọkụ na-arụ ọrụ na-emepụta nnyonye anya kpatara site na ntanye site na ikesa ikesa na mkpuchi mkpuchi nke eriri.

2) A na-ejikọta mgbaàmà ahụ na ibe ya site na mgbochi nke waya ala, ike na-enye ọkụ na nnyefe nnyefe, ma ọ bụ mmetụta nke ntinye aka na-eme n'etiti wires.

3) Ụfọdụ ihe dị n'ime akụrụngwa ma ọ bụ usoro na-emepụta okpomọkụ, nke na-emetụta nkwụsi ike nke ihe ndị ahụ n'onwe ha na ihe ndị ọzọ.

4) Igwe ndọta na ọkụ eletrik na-emepụta site na ike dị elu na ihe ndị dị elu na-emetụta nnyonye anya nke ihe ndị ọzọ kpatara site na njikọ.

Ntinye aka na mpụga – mmetụta nke ihe ndị ọzọ karịa akụrụngwa eletrọnịkị ma ọ bụ sistemu na sekit, akụrụngwa ma ọ bụ sistemu.

1) voltaji dị elu nke mpụga na ọkọnọ ike na-egbochi sekit eletrọnịkị, akụrụngwa ma ọ bụ sistemu site na ntapu mkpuchi.

2) Akụrụngwa dị elu nke mpụga na-emepụta oghere magnetik siri ike na mbara igwe, nke na-egbochi sekit eletrọnịkị, akụrụngwa ma ọ bụ sistemụ site na njikọta inductance.

3) Oghere nnyonye anya electromagnetic na sekit ma ọ bụ sistemu eletrọnịkị.

4) Okpomọkụ nke gburugburu ebe obibi na-arụ ọrụ adịghị eguzosi ike, na-eme ka nnyonye anya kpatara mgbanwe na paramita nke sekit eletrọnịkị, akụrụngwa ma ọ bụ akụkụ dị n'ime nke usoro ahụ.

2. Ụzọ nnyefe nke nnyonye anya electromagnetic

Mgbe ugboro nke nnyonye anya isi iyi dị elu, na ogologo ogologo nke mgbaàmà nnyonye anya dị ntakịrị karịa nhazi nke ihe a na-etinye aka na ya, enwere ike iwere mgbaàmà nnyonye anya dị ka mpaghara radieshon, nke na-eme ka ike eletrik dị n'ụdị ụgbọ elu electromagnetic. wee banye n'ụzọ nke ihe etinyere.N'ụdị njikọ na njikọta, site na dielectric insulating, njikọ nke mgbochi nkịtị na-abanye na usoro ntinye aka.Ihe nrịbama nnyonye anya nwere ike ịbanye na sistemụ site na ntụzịaka ozugbo.

3. Usoro iji melite ndakọrịta electromagnetic

Iji kwalite ndakọrịta elektrọnik nke ngwaahịa eletrọnịkị, ịgba ala, mkpuchi na nzacha bụ ụzọ bụ isi iji gbochie EMI.

1) Grounding

Grounding bụ ụzọ ntụgharị ọkụ eletrik n'etiti ngwa eletriki na eletrọnịkị n'ime sistemu ruo ebe ntụaka ala.Na mgbakwunye na ịnye ala nchekwa nchekwa nke akụrụngwa, ala na-enyekwa akara ngosi akara dị mkpa maka ịrụ ọrụ akụrụngwa.Igwe elu ala dị mma bụ ahụ anụ ahụ nke nwere ikike efu na efu efu, nke enwere ike iji mee ihe dị ka ihe ntụnye aka maka nyocha mgbaàmà niile na sekit, na mgbaàmà ọ bụla na-egbochi ya na-agafe na ya agaghị emepụta ụda voltaji.Otú ọ dị, ụgbọ elu ala dị mma adịghị adị, nke na-achọ ka anyị tụlee ma nyochaa nkesa nke ike ala, na-eduzi nhazi ala na nyocha, ma chọpụta ebe kwesịrị ekwesị ala.Enwere ike kewaa ụzọ ala ala ụzọ: ala na-ese n'elu mmiri, ntọ ala otu ebe, ntọ ala ọtụtụ, na ngwakọ ala.Maka usoro sekit, e nwere nhọrọ: mgbanaka sekit, ike ala, na mgbama n'ala.

2) mkpuchi

Nchekwa bụ iji elu mechiri emechi nke conductive ma ọ bụ electromagnet iji kewapụ oghere dị n'ime na mpụta.Na-ekpochapụ nnyonye anya radieshon na oghere.Kewara n'ime ihe mkpuchi elektrọnịkị, nchekwa ọkụ eletrik na mkpuchi oghere magnetik.

Enwere ike ime atụmatụ mkpuchi ahụ na ma ebe nnyonye anya yana ihe etinyere.Maka ntinye nnyonye anya, nhazi nke akụkụ mkpuchi nwere ike ibelata mmetụta na akụrụngwa ndị ọzọ gbara ya gburugburu;maka ihe a na-etinye aka, ọ nwere ike ibelata mmetụta nke nnyonye anya mpụga na ebili mmiri electromagnetic na akụrụngwa.

Nchekwa na-arụ ọrụ: Tinye ebe nnyonye anya n'ime ahụ mkpuchi iji gbochie ike eletriki na akara nnyonye anya ịbanye n'ime oghere dị n'èzí.

Nchekwa na-agafe agafe: idobe akụrụngwa nwere mmetụta n'ime ahụ mkpuchi ka nnyonye anya mpụga ghara emetụta ya.

3) Nzacha

Ihe nzacha pụtara na-ezo aka na usoro iji wepụta akara bara uru na akara izizi agwakọtara na mkpọtụ ma ọ bụ nnyonye anya.Ihe nzacha EMIbụ components iji nweta nzacha.

N'ezie, mgbe ngwaọrụ na-arụ ọrụ, ọ ga-emepụtakwa ụda dị iche iche.Mgbanwe ọkụ ọkụ bụ isi iyi nnyonye anya siri ike, na akara EMI ọ na-ebute ọ bụghị naanị na-adị ọtụtụ ugboro, mana nwekwara nnukwu njupụta.Site na mgbasawanye nke mgbaàmà ahụ, ụda ndị a na-egbochi ihe ndị na-esote ọkwa, na nchịkọta nke nnyonye anya dị otú ahụ nwere ike imecha mee ka arụ ọrụ na-adịghị mma nke sekit dum.N'iburu n'uche na a na-ehichapụ mgbaàmà mmepụta nke ngwaọrụ ahụ nwere nnukwu mkpọtụ na nnyonye anya doro anya na ngwaọrụ dị ala iji nyochaa ụda mkpọtụ ahụ, nnyonye anya na ngwaọrụ dị ala ga-ebelata, na usoro ahụ ga-arụ ọrụ nke ọma.

DREXSOnye isi ụlọ ọrụ EMI

Ọ bụrụ na ịchọrọ nchekwa EMI dị irè, DREXS na-enye durable na ihe nzacha EMI a pụrụ ịdabere na ya maka ngwa ọ bụla.Ihe nzacha anyị dabara adaba maka ngwa ndị ọkachamara na mpaghara ndị agha na ahụike, yana maka ebe obibi na ụlọ ọrụ mmepụta ihe.Maka ngwa chọrọ ngwọta omenala, ndị otu ọkachamara anyị nwere ike chepụta nzacha EMI iji mezuo ihe ị chọrọ.

Site na ahụmịhe afọ 15 na idozi nnyonye anya elektrọn, DOREXS bụ onye nrụpụta ntụkwasị obi nke ihe nzacha EMI dị elu maka ngwa ahụike, agha na azụmaahịa.Emebere ihe nzacha EMI anyị niile iji zute ụkpụrụ ụlọ ọrụ wee rube isi n'iwu EMC.Chọgharịa nhọrọ nke nzacha EMI ma ọ bụ nyefee arịrịọ ngụ aha omenala iji nweta nzacha EMI zuru oke maka mkpa gị.Maka ozi ndị ọzọ gbasara omenala DREXS na ihe nzacha EMI ọkọlọtọ, biko kpọtụrụ anyị.
