Kusarudza ano waya muchinjikwa-chikamu - basa rakanaka, asi basa

Mumwe vanonyatsokwanisa zvemagetsi kudzidza kukosha kutarisirwa mutoro pamusoro wiring anogona pakarepo kuita chikamu ano waya. The basa iri nyore, zviri kudzidziswa kugadzirisa sangano zvekushandisa Profile, kubva chikuru kune tertiary. Zvinofanira kurangarirwa kuti, nokusarudza waya, zviri nani kuti vanokubvumira yakakura kupfuura parutivi duku.

In maindasitiri miti Masvomhu ose anodiwa anoitwa nyanzvi vane unyanzvi hwakasiyana magetsi engineering, saka nemambure parameters takatsunga kwete nheyo 'kugadzira, kuti tine ", uye optimized maererano kurerutsa mari, pasi rwokugadzira mirayiro. Pane mwero mitemo magetsi mano pano, uye vari kutungamirirwa mainjiniya, achiita chikamu pakusarudza magetsi waya. RB (redhiyo zvivako Terms mano) zvinodiwa kuverenga rimwe zvemagetsi-wakachenjera.

Zvinetso kana vanhu vasina zvinodiwa zvakakwana, kuedza kuti kugadzwa kana wiring kuzvitsinhanisa mumusha mavo kana panguva yokurenda. Selection of waya muchinjikwa chikamu - zviri basa. Kuita izvozvo nepasipo unogona panguva yakanakisisa nezvisarudzo nokuva vaputse kuvimbika varinamire uye kushandura nomukondombera waya. Pamusoro nezvedambudziko rako vasingadi kunyange kuda kutaura rudzi moto.

Kuti tinzwisise zvakaipira zvikanganiso zviri kusarudzwa kubva waya anofanira kuziva mitemo nyore, inobva chikoro wefizikisi kosi.

saka:

The yemagetsi nemishonga ane muitisi riri Proportional kuti kureba kwayo uye resistivity zvakananga. Muchinjikwa-Chikamu pamusoro zvinopesana, zvakunoita navo nekwekupedzesera:

R = (ρ X L) / S,

apo:

• R - kukosha resistivity, akayera mu ohms;
• ρ - resistivity, i.e. ari kurwisa kuti muitisi iri acho 1 mm 1 M uye chikamu ^2;
• L - Kureba wiring, m;
• S - kondakita muchinjikwa-sectional nzvimbo mm ^2.

The resistivity kwakasiyana pakati simbi dzakasiyana. Somuenzaniso, nokuti sirivha, zviri pamusoro 0,016 Ohm x mm ² / m ^2, pane imwe Platinum - 0.1, uye kuti zvendarama - 0.02. Zvisinei, waya muchinjikwa-chikamu kusarudzwa razvino hakudi kushandiswa anokosha simbi (chikonzero chakajeka).

Zvino nokuti mutoro. Kusaita zvikanganiso zviri chitsama ano kuti dzichayerera iri tambo, zvakakwana kuziva nyore payakavakirwa mutemo Ohm kwakaita kuti dunhu rine resistive mutoro:

W = U x I,

apo:

• W - simba akayera mu watts or;
• U - mains voltage (pano zviri 220 volts);
• I - ano ukoshi (ampere).

Kutaura zvazviri, Volt-Amps zvakasiyana W, asi maererano kwakavakirwa, iro hunodzorwa yezvakaita basa mutoro (incandescent mwenje, Heaters uye zvichingodaro. P.), musiyano uyu anogona kuregeredzwa.

VaGumbo simba rose midziyo yemagetsi, zvinokwanisika kuti kuisa huwandu mutoro muna Watts kuti achaita kuti kusarudzwa Muchikamu kuitika pamusoro waya.

Zvadaro zvose nyore. Sezvo goridhe kana Platinum waya kashoma anoshandisa kunyange Abramovich kufarira ndemamwe simbi zvakawanda zvakajairika. Kana kusarudza chinoitwa vachida inodhura. waya, mhangura, ose mativi millimeter (kana sezvo unoratidzwa Electricians "mativi") anogona kupfuura kusvika 10 Amps. Mune ehupfumi ose aruminiyamu mwero 8 amps, asi zviri isingadhuri.

Kazhinji, kusarudza mudzimba ari kuitika waya muchinjikwa-chikamu anoitwa muchifarira aruminiyamu waya saizi nehafu dzakaenzana (nzira yokubudisa) uye polkvadrata (okuvimba). Appliance kana zvimwe vatengi simba-unoparadza zvinoda vakaparadzana waya bushings kondakita chikamu iri 2.5 mm ^2.

Zvakakosha kuyeuka kuti chokubatanidza mhangura waya pamwe aruminiyamu hazviiti. pakupedzisira nokuvhiringidza ichi anorasikirwa ayo conductive ehupfumi.
