I nā makahiki i hala iho nei, me ke kūkulu hohonu ʻana o nā ʻenehana hou ma Kina, ka hoʻololi piha ʻana o nā kahua kahua 5G, ka hoʻohana nui ʻana i nā lako uila uila a me ka hoʻomohala wikiwiki ʻana o ka mana photovoltaic, ke loaʻa nei nā koi no nā mea hana haʻahaʻa haʻahaʻa. kiʻekiʻe a kiʻekiʻe.No nā ʻoihana ʻoihana i ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā wahi ʻeha, hoʻoheheʻe ʻia ka hihia kaʻapuni arcing mamao palekana a me ka hawewe distortion kū'ē hoʻāʻo papahana, Delta, Delta mea kani ma ka hui ʻana i nā kumu loea kiʻekiʻe e hoʻomohala i ʻelua mau wahi e like me nā koi o ka hoʻāʻo kūikawā. nā mea hana, i hoʻolālā ʻia e kōkua i nā ʻoihana e hoʻoponopono i ka bottleneck o ka noi huahana, e hoʻokō i ka makemake o ka mea hoʻohana, e hoʻomaikaʻi i ka maikaʻi o ka hana huahana.

Molded case circuit breaker arcing safe distance test stand is mainly for plastic shell type circuit breaker in the process of installation and use, considering safety distance is not enough and can cause harm, like arcing fault pono e aʻo i ka plastic shell type circuit breaker on ʻO ke kī nui i ke kaʻina hana o ka ʻike ʻana i kahi mamao palekana, me ke kaapuni pili hoʻāʻo hou, nā koi hou aʻe a me nā ʻano hoʻāʻo, a me nā mea ʻē aʻe. degere o ka mana arc, a me nā kuhikuhina mamao palekana palekana huahana a me nā manaʻo hoʻonohonoho i manaʻo ʻia no kēlā me kēia

ʻO nā pōʻino o nā lele lele

ʻO ka mahana o Arc e like me ke kiʻekiʻe o nā kaukani degere Celsius, arc ponoʻī nō hoʻi ka conductivity uila, he koʻikoʻi loa ka pōʻino., e hoʻololi i ka ʻoihana uila uila uila jet o arc, hiki ke hoʻopololei pololei i ka switchgear, ka papa hoʻolaha, e like me ka hoʻopaʻa ʻana i ke kiʻi metala, e hōʻino ʻia ka mea hoʻokele metala, ʻike ʻia nā laina ʻano like ʻole o ka piʻi ʻana o ka uila, ka mea puhi ahi, nā lako ahi, hana i ka ʻO ke kūlana kahiko o ka insulation, a i ʻole nā ​​hewa pōkole, pahū, ahi, hoʻoweliweli i ka palekana o nā ola a me nā waiwai, I ka ʻaila, kemika, ka mining a me nā ʻoihana ʻē aʻe, pono e nānā nui ʻia i ka pōʻino o ke arc.

Hoʻopuka ʻo MCCB i kahi arc i ka wā e hoʻokaʻawale ʻia ai kāna mau mea hoʻopili neʻe a me nā pilina paʻa, a ʻo kahi hapa o ke arc a i ʻole kinoea i hoʻokuʻu ʻia e hoʻokuʻu i ke āpau arc mai ka lako mana o ka mea haʻihaʻi.ʻO ke arc ponoʻī he au nui.He mea maʻalahi ke hana i nā pōʻino kaapuni pōkole a hoʻopaʻa ʻia ma waena o C exposed conductor a me ka lepo.No ka hōʻoia ʻana i ka palekana, pono ka mea hoʻohana e mālama i kahi mamao mai ka ʻikepili i hāʻawi ʻia e nā mea hoʻohālike huahana a i ʻole nā ​​kikoʻī.

Hoʻoheheʻe ʻia ka pahu kaʻa kaʻa i ka wā e wāwahi ai i ka manawa pōkole nui, ʻo ka ʻokoʻa a me ke ʻano hoʻokaʻawale ʻana, ʻo ka ʻāpana o ka arc a i ʻole ka ionized gas arc e hoʻoheheʻe ana i ka waha mai ka hopena o ka mana kaapuni, ʻo ia ke ʻano o ka nui o kēia manawa, maʻalahi. e hoʻokumu i waena o ke kino conductive a me ke kino i hoʻopaʻa ʻole ʻia a me ka "ground" (nā pūʻulu piha o nā mea hana o ka pūpū metala e hoʻopaʻa ʻia ana) o ke kaapuni pōkole interphase a me ka ulia pōkole kaapuni.No ka hōʻoia ʻana i ka palekana, pono ka mea hoʻohana e haʻalele i kahi mamao e like me ka ʻikepili i hāʻawi ʻia e ka laʻana huahana a i ʻole ka manual aʻoaʻo.Inā ʻaʻole lawa ka mamao o ke kiʻekiʻe o ka pahu hoʻolaha a me ke keʻena, hiki ke koho ʻia nā huahana me ka mamao arc liʻiliʻi a i ʻole arc zero e hōʻoia i ka palekana o ka hoʻohana ʻana i ka uila.

ʻO ka mea hoʻoheheʻe kaapuni i hoʻoheheʻe ʻia i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ʻōnaehana ʻōnaehana nui, akā i ka wā wāwahi e hana ai i ka arc, arc i waho o ke ʻano o ka huahana i arc, arc he mea pōʻino, ʻo kāna ʻike pono e hoʻokō i nā kūlana kūpono a me nā ʻano, ʻo nā ʻano kumu nui. e ho'ēmi i ka mamao arc e komo pū me ka hoʻomaikaʻi ʻana i ke ʻano o ka hoʻopili ʻana a me ka ʻōnaehana hoʻopau arc e hoʻomaikaʻi i ka hana o ka hoʻopau ʻana i ke arc, ka hoʻohana ʻana i ka mea hoʻoheheʻe arc, ka hoʻohana ʻana i ke ʻano palena palena o kēia manawa, ka hoʻokomo ʻana i ka ʻehā o ka hanauna ʻehā o ka hoʻomaha ʻana, a me ka hoʻopau ʻana i ka pahu pahu keena.

Molded case circuit breaker waveform distortion resistance ho'āʻo kū mea nui ma ka malamalama o ka kūikawā noi kūlana o ka plastic shell type circuit breaker, e like me ka hoʻokaʻawale like ʻole o ka ukana nonlinear maʻamau a me ka puʻunaue harmonic rate, a me ke kaʻina hoʻāʻo o ka hoʻokolohua simulation, systematic analysis. ma ka ʻikepili hoʻāʻo hiki ke hoʻohālikelike i nā ʻano haʻahaʻa harmonic nonlinear, hoʻouka hopena, haʻahaʻa malignant;Hiki ke hoʻolālā mua ʻia kona ʻano haʻahaʻa a me ka mana hana e like me ka noi hoʻāʻo, a hiki ke hoʻouka ʻia e like me ka manawa holo i hoʻonohonoho ʻia.He maʻalahi a maʻalahi ka hana ʻana o nā mea hana, a ua hoʻohana nui ʻia i ka ʻōnaehana hoʻokolohua uila a me nā ʻano o nā ʻano mana uila hoʻomohala huahana hoʻāʻo.

Harmonic generation device in power system is the harmonic source, is a non-linear uila lako.Me ka hoʻohana ākea o nā mea uila uila mana nui a me nā ukana nonlinear like ʻole i loko o ka ʻōnaehana, ua ʻike nui ʻia ka pollution harmonic i hana ʻia e lākou.I mea e kāohi ai i ka harmonics o ka ʻōnaehana, pono mākou e hoʻomaopopo i nā ʻano o kēlā me kēia kumu harmonic.

Hoʻokaʻawale ʻia nā kumu harmonic like ʻole i:

(1) Kumu harmonic ʻano o kēia manawa.

Loaʻa i ka ʻōnaehana harmonic nā hiʻohiʻona o ke kumu o kēia manawa, a ʻo kāna ʻike harmonic e pili ana i kāna mau hiʻohiʻona ponoʻī a ʻaʻohe mea pili i nā ʻōnaehana ʻōnaehana.ʻO ka mea hoʻoponopono o ka kānana inductance ʻaoʻao DC no ke kumu harmonic ʻano o kēia manawa.

(2) kumu harmonic ʻano uila

ʻO MCCB waveform distortion resistance test bench ua like ia me ka mana kiʻekiʻe-hana harmonic generator, ʻekolu-phase hana kūʻokoʻa, hiki ke hana i ʻekolu-phase, hoʻokahi-phase mode, harmonic manawa a hiki i 41 mau manawa.Hiki ke hoʻolālā kūʻokoʻa ka pae a me ka amplitude o kēlā me kēia harmonic, hiki ke hoʻohālikelike i ke kūpaʻa maʻamau a me ka ukana inductive a me ka ukana nonlinear paʻakikī.Hiki ke hoʻohālikelike a hana hou ʻia ka harmonic i hana ʻia e nā ukana like ʻole.

Loaʻa i nā ʻāpana papahana ka nalu kumu a me ka volta harmonic, ka manawa, ka mana, ka pae, amplitude, etc.

Hiki ke hoʻololi mau ʻia ka amplitude o ka ukana hopena.

Hiki iā ia ke hoʻomaopopo i kahi simulation o nā ʻano hana like ʻole, e like me ka lōʻihi o ka mokuʻāina, ka uila, ka manawa, nā ʻāpana mana, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia e like me ka manawa i hoʻonohonoho ʻia.

He kiʻekiʻe ka pololei o kēia manawa, ʻo ka pololei a hiki i ± 1%, 10A ma lalo ʻaʻole i emi iho ma mua o ka hoʻohui a i ʻole 0.1A;

THD haʻahaʻa harmonic (3-5) precision ʻaʻole i oi aku ma mua o ±2%, hookahi harmonic deviation he ±8%, hookahi hawewe distortion rate maʻiʻo ≥40%, huina harmonic distortion rate ≥100%;

I ka manawa like, loaʻa i nā mea hana ka hana o ka hoʻoulu hou ʻana o ka ikehu AC, hiki iā ia ke hānai i ka 100% AC ikehu puka o ka huahana i hoʻāʻo ʻia i ka mana mana, me ka ʻole o ka hoʻoulu ʻana i ka wela, ka mālama ʻana i ka ikehu a me ka mālama ʻana i ke kaiapuni.

ʻO ka hana hou ʻana o ka hawewe: hiki ke hoʻonohonoho pono ʻia ka hāmeʻa e like me ka faila hawewe i hoʻopaʻa ʻia a hōʻuluʻulu ʻia paha ma kahi, i ʻike ai i ka hana e hiki ke hana hou ʻia ka hawewe ukana ma kahi a i ʻole nā ​​hiʻohiʻona ukana i koi ʻia.

Hiki ke hoʻonohonoho ʻia nā kūlana simulation e like me nā koi:

1) Hiki ke hoʻohālikelike i ka ukana ʻekolu a me ka ukana hoʻokahi;

2) Hiki ke hoʻonohonoho kaʻawale ʻia ka volta, ka manawa a me ka mana o ka hawewe kumu a me ka hawewe harmonic;

3) Hiki ke hoʻonohonoho ʻia ka hawewe kumu a me ka volta harmonic, ka manawa a me ka mana i kēlā me kēia amplitude, phase, power factor a me nā ʻāpana ʻē aʻe;

4) Hiki ke hoʻonohonoho kaʻawale ʻia nā ʻāpana amplitude a me ka pae o kēlā me kēia harmonic, kūʻokoʻa kekahi i kekahi, a ʻaʻole pili kekahi i kekahi;

5) Hiki ke hoʻololi mau ʻia ka amplitude o ka ukana hopena;

6) Hiki ke hoʻomaopopo i nā ʻano like ʻole o ka simulation mokuʻāina hana, ka lōʻihi o nā mokuʻāina like ʻole, ka uila, ka manawa, nā ʻāpana mana;

7) Hiki ke hoʻonohonoho kūʻokoʻa.
