Pamusoro pekushandisa low voltage circuit breaker

Teerera kune anotevera mapoinzi paunenge uchiisa yakaderera-voltage circuit breakers:

1.Usati waisa mutsara wedunhu, zvakakosha kutarisa kana kusvibiswa kwemafuta panzvimbo yekushanda kwezvombo yakabviswa, kuitira kuti irege kupindira nekushanda kwayo.

2.Paunenge uchiisa chivharo chedunhu, inofanira kuiswa vertically kuti irege kukanganisa kurongeka kwekuita uye pa-off kukwanisa kwekusunungurwa, uye kuchengetedzwa kwekudzivirira kunofanira kuiswa.

3.Apo dhizaini yemagetsi yakabatana nebhari yebhasi, hapana torsional stress inobvumirwa, uye kukodzera kweiyo pfupi-circuit tripping value uye thermal tripping value inofanira kuongororwa.

4. Mutsetse wemagetsi unouya unofanirwa kubatanidzwa kune wepamusoro mbiru musoro padivi pekamuri yekudzimisa arc, uye mutsetse unobuda unofanirwa kubatanidzwa kune wezasi wekoramu musoro padivi rekuburitswa, uye tambo yekubatanidza ine yakakodzera mhiri-chikamu nzvimbo inofanira kusarudzwa maererano nemirairo kuti isakanganisa rwendo rwekupfuura.Izvo zvinodzivirira zve clasp.

5.Iyo wiring yemaitiro ekushanda uye magetsi emagetsi emagetsi emagetsi anofanira kunge akarurama.Panguva yekushanda kwemagetsi, kushandura kusvetuka kunofanira kudziviswa, uye simba-panguva haifaniri kudarika kukosha kwakatarwa.

6.Panguva yekuvhara uye kuvhura nzira yevanobatika, hapafanirwe kunge paine jamming pakati pechikamu chinofambiswa uye zvikamu zvekamuri yearc.

7.Kubatana kwepamusoro pekubatana kunofanira kunge kwakadzika, uye kushamwaridzana kunofanira kuva kwakasimba mushure mekuvhara.

8.Iyo pfupi yekufamba rwendo kukosha uye thermal rwendo kukosha kunofanirwa kuiswa nemazvo maererano nemutsara uye mutoro zvinodiwa.

9.Usati washandisa, shandisa 500V megohmmeter kuti uone kupikisa kwekudzivirira pakati pemuviri mhenyu uye chimiro, pakati pemapuranga, uye pakati pesimba remagetsi uye rutivi rwemutoro apo mhepo inoputika inobviswa.Ita shuwa kuti kudzivirira kwekudzivirira kwakakura kupfuura kana kuenzana ne10MΩ (marine circuit breaker Kwete pasi pe100MΩ).

Izvi zvinotevera zvinodikanwa zve low-voltage circuit breaker wiring:

1.Kune zviteshi zvewaya zvakafumurwa kunze kwebhokisi uye zviri nyore kusvika, kudzivirira kudzivirira kunodiwa.

2.Kana iyo yakaderera-voltage circuit breaker ine semiconductor tripping device, wiring yayo inofanira kusangana nechikamu chekutevedzana kwezvinodiwa, uye chiito chekugadzirisa chigadziro chinofanira kuvimbika.

Izvi zvinotevera kuisirwa, kugadzirisa uye bvunzo zvinodiwa zveDC fast circuit breakers: 1. Panguva yekuisa, zvinodikanwa kudzivirira muparadzi wedunhu kubva pakudonhedza, kudhumhana uye kudengenyeka kwechisimba, uye kutora matanho akakodzera ekurwisa-kudengenyeka pakati penheyo chiteshi simbi uye. hwaro.

2 .Kureba pakati pepakati pemapango emutsigiri wedunhu uye chinhambwe chemidziyo iri pedyo kana zvivako hazvifaniri kunge zvisingasviki 500 mm.Kana ichi chinodiwa chisingakwanisi kuzadzikiswa, zvinodikanwa kuisa arc barrier iyo kureba kwayo kusiri pasi pehupamhi hwese kweiyo-pole switch.Panofanira kuva nenzvimbo isingasviki 1000mm pamusoro pekamuri yekudzimisa arc.Kana ichi chinodiwa chisingagoni kuzadzikiswa, kana shanduko yemazuva ano iri pasi pe3000 amps, zvakakosha kuisa arc shield 200 mm pamusoro pekuvhiringidza kwemugadziri wedunhu;Isa arc baffles.

3.Iyo insulating lining mukamuri yekudzimisa arc inofanirwa kunge yakamira uye nzira yearc inofanira kuvhurwa.

4.The contact pressure, kuvhura kure, kuputsa nguva, uye kupikisa kwekudzivirira pakati pearc yekudzima kamuri yekutsigira screw uye iyo yekusangana mushure mekusangana kukuru kunogadziriswa kunofanirwa kusangana nezvinodiwa zvechigadzirwa technical zvinyorwa.
