Ka pololei i waeia o ka huakai kaapuni a nalu

Pinepine, i ka manawa e hele mai e puku i ka pou pilina a me ka huakai kaapuni a nalu pono e auou caiaiai ma ka hoʻoponopono 'ole hou no? Ieoaeunoaa. I ka kipa i ka Shop electricians aneane mau ke ike i ka 99% o ka laulā o ka huakai kaapuni-nalu i manao maalea me ka'īkoi hālawa C. Alaila, ia i mea i keia mea i ka wale a me ka hiki pololei mana. He 'atikala ua hoʻolaʻa ai i ka loiloi' ia o kekahi o ka mea nui 'ano o ka huakai kaapuni-nalu -'īkoi hālawa.

Ka'īkoi curves o ka huakai kaapuni a-nalu komo o nā māhele:

• triggering overload hoomalu (thermal): ka mea kiekie oia ka mea pono, o ka pōkole o ka la i manawa;
• ka'īkoi ma pōkole i puhi ai (electromagnetic a hoʻokuʻu) ina o ka pono aku i ka i wahi o ka 'ohana ka palekana huakaʻi manawa, ua emi mai o 10 milliseconds.

No ka pōkole-kaapuni paialewa ma luna 20 manawa i ka Loipālākiōʻikena, manawa-he ano (aku curves) mai,ʻaʻole i lawa miomio make.

Nā polokalamu nui pōkole-kaapuni paialewa ua wehewehe aku ma kaʻikena kali curves (kēia pono a me ka ikehu). Ka huina manawa ia aku hiki e kaha like kokekau i ka palima o ke kumukuai o ka lākiō (I2t) / (I) 2.

O kéu hoʻomaopopo i ka selectivity ma waena o nā huakai kaapuni-nalu

Ma ka superimposing kaapuni nalu hālawa i ka hālawa kupuʻia kaapuni nalu ke kaha paha keia me ka hui pu ana o na manao selectively ma ka hihia o ka overload (selectivity no nā aiee o ka papa, a hiki i ka setpoint oi electromagnetic a kuapo). Oia hōʻoia mea kūpono ka wā kekahi o ka huakai kaapuni nalu elua mai ka hoʻoneʻe 'ia paha wahi; no ka mea, he manaʻo me ka ikaika napoo ana no hoi, ua 'ike hiki ke loaʻa' ana i loko o ka papaʻaina selectivity. E hoao i ka selectivity i pōkole-kaapuni ia mea pono e hoohalike i ka ikehu ano o na mea i elua.

Laʻana: e like me ka'īkoi hālawa i loko o ka huahelu, o ka huakai kaapuni nalu iC60 Schneider uila Acti 9 (hālawa C, he palena iki kala pono o 20 A) hoʻopioʻikena 100 A (a laila 5-pa i ka Loipālākiō papa In) o:
• ma ka liʻiliʻi 2 kekona;
• kekahi i kā mākou o 7 kekona.

Manawa au i ano

Koho i ka manawa pono ano pono ouschestvlyatsya e like me ke 'ano i malama i ka'ōnaehana like no ka hoomalu ana i ka pou'ōnaehana koi i manawa okoa. Ma keia e pili ana, i loko o ka nakeke ka unahiʻole, i 6 kekahi mau curves.
