Gịnị bụ atụ nkesa

Instrument nkesa na-eji RPA analysis na sekit na sekit n'ihi na ugbu a na voltaji ụkpụrụ. Nke a bụ mkpa iji ọsọ agba anọ nchedo oge ike na-arụ ọrụ dị ka setpoint, eletriki engineer n'oge nyere. A, na sekit na sekit na-eji RPA ji atụ ugbu a na voltaji nkesa. Ka anyị tụlee nke ọ bụla ụdị iche iche.

Voltaji nkesa na-eji na-echebe nghazi nke a ụdị nkwado, nke a na-eduziri na-akwanyere ndị ngụda adọ mgbanwe akụkụ ma hazie nchedo n'ụwa kpatara na-enyemaka nke coils ejikọrọ na ihe na-emeghe triangle atụmatụ.

Atụ voltaji nkesa na-rụrụ na ọtụtụ Kern: onye na-ejikọrọ na a "kpakpando" ụkpụrụ, nke abụọ - na a "gbajiri Delta". Taa, n'ichepụta osisi emepụta nkesa na a atọ ntụmadị, nke na-eji maka aza ajụjụ.

N'ihi RU-35-110 kV arụnyere atọ -phase transformer voltaji. Òtù nke ọ bụla nke onye ogige n'ịnyịnya ígwè ọrụ. N'ihi RU 6-10 kV na-akacha eji atọ-adọ TN na otu ngwugwu.

Atụ ugbu a nkesa na-eji niile Uzbekistan ma guzosie ike na a phased n'ụzọ. Ndị a nkesa na-mere nke monolithic taya, nke bụ isi cell. Bus ofu abụọ asọfe ebe, e nwere ike ịbụ na ọtụtụ, onye ọ bụla asọfe (dịrị gaba n'ime ebe isi) e mere maka a kpọmkwem na klas nke ziri ezi na kpọmkwem ike.

Cores bụ mmepụta circuit nchedo, n'ihe na metering. Ọ dị mkpa ka na nke ugbu a nkesa ka mgbe nwere raskorochennyh isi, ma ọ bụghị eriri igwe ga-akpọ, na-arụ ọrụ na ihe ize ndụ nke ịbụ ndị gburu electrocution.

Mgbe wụnye ji atụ ugbu a nkesa ga-ga dị ka esereese input-mmepụta voltaji (L1 - input A2 - mkpụrụ). On a na-adabere na direction Vektọ nke ugbu a nke ọ bụla na-adọ. Dị ka ihe n'ụzọ anụ ahụ, n'etiti Vektọ nke osimiri, nke windings jikọọ na a "kpakpando" ga-abụ 120 degrees. Ọ bụrụ na n'ihi ihe ụfọdụ na-Vektọ na-ndokwa dị iche, ị ga-agbanwe njikọ isi TT, swapping mmalite ruo ọgwụgwụ.

Ugbu nkesa na-eji nchedo obere sekit na sekit na nzukọ nke ndị esi nchebe. Atụ ugbu a nkesa - ihe dị mkpa àgwà nke oge a electrification, ọ bụ a ihe mmetụta, nke jikoro nke ugbu a bara uru na ya direction.

Eletriki transformer na-eji na-efu usoro. Nke a mmewere mkpa maka RU-0,4-6-10 kV, ebe ọ bụ na ọrụ nke transformer (ke ufọk donut) iji chebe circuit elu voltaji n'ala kpatara. Ya bụ isi cell - bụ ya onwe ya a feeder, nke na-gabiga a bagel. Ebe ọ bụ na nke abụọ napụrụ uru nke dịgasị dị ka a mgbanwe nke ndọta nke feeder.

N'ihi ya, nkesa n'ihi na ugbu a na voltaji n'ihe - bụ ntọala nke nchebe. Site na ha oge a microprocessors nwere onwe ha gbakọọ ike, ndị na-eguzogide nke yinye ngalaba, na akụkụ n'etiti ugbu a na voltaji. Nchoputa na-adịghị mkpa a ga-enyocha, dị ka ngwá ọrụ ọgbara ọhụrụ a rụrụ na ọhụrụ technology.

Taa, ezi a ewu ewu na ngwaọrụ, nke bụ a ngwọta zuru ezu na-agụnye circuit Oké mmali, disconnectors, nakwa dị ka ewu na-ugbu a na voltaji nkesa - na ọ bụ adaba na ezi uru.
