Switchgear Unit (CRU): mitundu, makhalidwe, akuti

Nkhaniyi itithandiza kudziwa za switchgear wathunthu. makhalidwe luso lawo, mitundu ndi kuika adzapatsidwa.

Mbali

Switchgear Unit (CRU) - chipangizo wopangidwa mwa matabwa, amene kuwonjezekeredwa mu zikuchokera:

• makina kuyamba ndi mphamvu zotha zida kasamalidwe;
• chipangizo chitetezo
• achepetsa chipangizo;

Komanso zigawo zina optional, anasonkhana ndi wokonzeka ntchito.

Cholinga kulandira ndi kugawa zina magetsi Intaneti atatu gawo ndi pafupipafupi opaleshoni 50 Hz ndi voteji oposa 1000 V.

Switchgear Unit (CRU) lagawidwa mitundu iwiri, kunja ndi mkati unsembe. Zomera m'nyumba anayikidwa mu kapena pa malo a. makina onga anasonkhana ndi busbar lapansi. Pamene ntchito voltages opaleshoni pamwamba 35 kV ntchito mpweya Intaneti kudzipatula 110 kV kutchinjiriza ndi chimateteza mpweya.

Monga ulamuliro, mu switchgear ntchito masiwichi ano mkulu-voteji zingalowe ngati chitetezo ndi kusintha chipangizo, koma pali zambiri lotha zomera kuti amene anaika masiwichi mafuta.

Kufalitsa makabati, switchgear RN 6 anapangidwa ntchito panja ndipo anawagawa mitundu iwiri ya ntchito: pakubwezeretsa, mu mbali zonse ndi mbali akuyang'ana bolodi wapadera, ndipo n'kupuma, kumene mbali zonse ndi mbali anaika moyo wautali utumiki.

Unsembe wa unsembe panja

Switchgear panja unsembe ayenera kukonzekera msonkhano, kotero loyamba maziko onse anagwira. Maselo kusuntha mu mawonekedwe odzaza pamaso zipangizo zonse zakonzedwa. Kenako unpacked ndi trolley anagubuduza kunja kwa nyumba imene switchgear waikidwa. Ikani selo dongosolo malinga ndi dongosolo. Unsembe akuyamba ndi koopsa. Kamodzi kutsimikizidwa unsembe olondola a nduna ya, gulu lotsatira. Nkofunika kuti maselo alibe kuima pa cham'mbali.

Mizere pamwamba pa denga kukhazikitsidwa m'mabokosi anaika. M'pofunikanso kuti apereke kuyatsa m'dera pafupi mukachipinda. Mkulu-voteji chingwe kudzera mzere n'kukathera switchgear pa apeza mu chitseko kumbuyo kwa nduna ya. Kenako switchgears unsembe panja wokonzeka ntchito.

Kulengedwa

switchgears Calculated (KRU) 6/10 kV voteji ayenera kuonetsetsa ntchito yachibadwa mbali zonse wokwera m'menemo. KRU ofanana mu maonekedwe ndi lalikulu selo zitsulo, mkati amene wokwera switchgear, chitetezo ndi zipangizo wothandiza. Chivundikiro akunja selo kulengedwa kuchokera mapepala zitsulo, chopangidwa kuonjezera mphamvu structural ndi chitetezo yochepa dera atsopano a zipangizo zina ili pafupi.

Kufalitsa makabati, switchgear RN 6 okonzeka ndi Kutentha wapadera m'deralo, limene panopa-kuyeza zipangizo zambiri ntchito m'nyengo yozizira.

Zofunika ndi kusintha mphamvu

Switchgear Unit (CRU) 10 kV ali Zotsatira zolongosoka mwadzina:

• kotunga opaleshoni voteji - 6, 10, 35, 110 kW;
• mafakitale opaleshoni mzere pafupipafupi - 50 Hz;
• Zikugwira ntchito Current - 630 A;
• tripping apano - 12,5, 20, 25, 35, 40 Ka;
• kutchinjiriza - mlengalenga;
• lembani dera - wosatsogoleredwa;
• kutayipa panopa thiransifoma - akukankha-6;
• kutayipa mphamvu thiransifoma - TM 25;
• Drive Mtundu - magetsi.

Dera switchgear kukana anatsimikiza zochokera magawo zida umene wamangidwa mu chipangizo lophimba wokwera kuti izo galimoto. Kusintha zipangizo, amene anaika mu switchgear, ayenera bwinobwino ntchito pa katundu oveteredwa ndi kupirira mayesero mkombero pa mkulu kumatula panopa, zimene zalembedwa mu specifications zipangizo mkati.

Membala slider ndi digiri ya chitetezo

Retractable chinthu chimene ndi zida kusinthitsa, akhoza opatsirana onse pamanja ndi umakaniko. Pochita zimenezi, ngolo ya ndidzadutsa pa njira ngakhale ❖ kuyanika popeza ali ndithu zambiri kulemera.

makabati onse switchgear muyenera kukhala omasuka pa ntchito ndi tinapangidwa chitonthozo unsembe, kukonza ndi m'malo mbali. Mu kwambiri makabati switchgear pa trolley kutsetsereka anagubuduza kunja kwa maselo tithe kugwira ntchito polankhula kwa anzanu ndi yoikidwiratu a dera waukulu disconnector logwirana mawindo wapadera.

Malinga ntchito, unsembe angakhale mtundu wina wa ntchito. CRU ayenera kutsatira Akasakaniza ndi makina structural mphamvu, kutchinjiriza ndi kukana kuti zinthu aukali opaleshoni. Category malawi Crewe:

• V3 - lakonzedwa kuti ntchito m'madera ndi makope zachilengedwe mpweya;
• V4 - lakonzedwa kuti zipinda ndi nyengo yokumba.

Kamangidwe ka switchgear ndi wokhazikika pa Phokoso limene zimenezi pa kusinthitsa osinthasintha masiwichi mkulu-voteji, komanso pamene anasamutsa unit. Pankhaniyi, zipangizo onse ayenera kugwira ntchito, ndipo kulandirana chitetezo sanalembedwepo pa ntchito pa mitengo mwadzina.

Switchgear angathe kupanga zinthu zosiyanasiyana nyengo ntchito magetsi a m'deralo kapena kuzirala.

yokumba

Pamene ntchito switchgear kufunika nthawi bungwe anayendera luso ndi kusamalira zipangizo, amene aikidwa mu khungu, komanso kusaka.

Kuyang'aniridwa ndi ntchito zida nawo zamagetsi ntchito kapena yemwe ntchito ya unsembe. Malinga ndi zofunika panopa chitetezo, kugwira ntchito ndi makhazikitsidwe magetsi sikuloledwa munthu, pamene ntchito ndi KRU ayenera osachepera awiri.

Antchito amene zikugwira unsembe kukonza ayenera aphunzitsidwe ndi ndi kulolerana gulu osati poyerekeza IV, ndi Ayeneranso kudziwa za zipangizo mu msonkhano switchgear, ndi kupereka njira magetsi ntchito mbali.

Unsembe ndi voteji opaleshoni 35 kV

Switchgear mkulu voteji mndandanda BM-4 ntchito kufala mphamvu Intaneti atatu gawo ndi mafakitale mains pafupipafupi 50 Hz ndi voteji opaleshoni 35 kV.

Switchgear selo ndi dongosolo mchimake ndi mapepala kanasonkhezereka zitsulo amene anagwirizana ndi china chotulutsa kapena rivet. Mkati wokwera masiwichi mkulu-voteji, voteji tiransifoma, switchgear, zipangizo ndi isolator.

Chotero switchgear anaikira utumiki ziwiri. Pamene anaika mu ang'ono-kakulidwe zomera wobala kusinthidwa KRU njira utumiki. Kukhalabe kutentha mu maselo, pali khungu. Komanso mpumulo kuthamanga, amene angaoneke ngati modes ntchito mwadzidzidzi kapena vuto mafunde kusokoneza kuli nthambi amene anaika pa ntsoyi ya selo.

Zida chizindikiro K-63

Switchgear chizindikiro K-63 amapangidwa thupi zitsulo sankalimbana nafe kuliika kwa zogwiriziza, mkati limene liri lonse zitetezeni switchgear ndi thiransifoma zida. Switchgear mtundu switchgear K-63 komanso ena, ukunenedwa kwa HIV ndi kufalitsa magetsi mu Intaneti atatu gawo ndi pafupipafupi mafakitale 50 Hz ndipo ndi voteji opaleshoni ya 6 kV.

Nkhani ina KRU K-63 ndi kuti angagwiritsidwe ntchito ngati chipangizo thiransifoma. Waukulu kusinthitsa zipangizo K-63 ndi mkulu-panopa masiwichi BB / Tel ntchito yolandirana electromechanical kapena MPD.

Maselo K-63 anapangidwa kuti unsembe mu malo, ndipo thiransifoma akhoza ili panja. K-63 ndi anasonkhana ndi dongosolo limodzi busbar, kumene magetsi akudyetsedwa kudzera mkulu-voteji switchgear selo kulowa mu anakonza padengapo.

Unit K-594 mtundu: ulemu

Switchgear KRU chizindikiro K-594, ngati khwekhwe onse pamwamba, ntchito voteji Intaneti kV 6-10 ndi pafupipafupi opaleshoni 50 Hz.

Monga ulamuliro, KRU K-594 ntchito substations, zomera mphamvu, maofesi ulimi njanji. Switchgear msonkhano KRU-594, mtengo wa potsata pa katundu ndi kugula dera, wangwiro polumikiza Motors mkulu-voteji ndi zina makina magetsi. Ubwino waukulu switchgear ndi:

• actuators onse magetsi anasonkhana ku selo imodzi ndipo Ndakwaniritsa pa fakitale;
• Izo kumawonjezera chitetezo cha mbewu yokha, komanso ogwira ntchito;
• onse a zinthu zovuta kwambiri ndi wokwera pa anagubuduza kunja ngolo, zimene zimachititsa zovuta ntchito pa ntchito yokonza zipangizo;
• maselo KRU si bulky, choncho kwambiri kupulumutsa danga mu chipinda.

Switchgear Unit (CRU) K-594 mndandanda ndi specifications kuti akhoza kusintha pa nkhani za kuwonjezeka kapena mwayamba kufooka imaŵerengedwa akalozera mwadzina wa ogula, umene chikugwirizana switchgear.

Pomaliza

KRU - ndi njira yodalirika kugwirizana ogula ndi lofunika kwambiri odalirika ndi yosavuta kugwiritsa ntchito, ndi kukonzanso zosavuta ndi kukonza. Iwo achita kutchuka kwawo mu dziko msika monga zida zodalirika mphamvu kufala.
