Khoom Description
Nws txais ib tug ncej-hom peb-theem khoom- kaw ncej kev sib xyaw ua ke, nrog rau tam sim no transformers thiab voltage sensors integrated nyob rau hauv tus ncej. Ua ke nrog ib qho chaw ruaj khov - hlau nplaum kev khiav hauj lwm mechanism thiab peb -theem linkage transmission system, nws ua tiav synchronous thiab kev sib koom ua haujlwm ntawm tag nrho peb theem.
Cov cuab yeej txhawb nqa ob qho tib si hluav taws xob qhib thiab kaw nrog rau cov hom kev taug kev los ntawm phau ntawv. Cov txheej txheem taug kev los ntawm phau ntawv yog nruab nrog lub tshuab ua haujlwm sib cuam tshuam los tiv thaiv kev ua haujlwm tsis raug, thiab ua haujlwm - hauv lub tshuab hluav taws xob ua kom pom tus naj npawb ntawm kev qhib thiab kaw haujlwm hauv lub sijhawm.
Nws muaj kev tiv thaiv IP65 thiab lub neej txhua yam tsis pub tsawg dua 10,000 lub sijhawm ua haujlwm, ua rau nws yog ib qho tseem ceeb ntawm cov cuab yeej siv los txhawb kev hloov kho cov phiaj xwm ntse thiab ua kom muaj kev nyab xeeb thiab ruaj khov. Interlock hom Recloser siv lub tshuab nqus tsev ua lub arc - tua nruab nrab, muab kev ua tau zoo thiab txhim khu kev qha arc - tua kev ua haujlwm.
Qhov ntsuas hluav taws xob tam sim no yog 16 kA, qhov ntsuas luv luv - lub sijhawm tiv thaiv tam sim no yog 16 kA rau 3 vib nas this, thiab qhov ntsuas luv luv - lub peev xwm tawg tsis pub tsawg dua 30 ua haujlwm. Cov cuab yeej tuaj yeem teb sai sai rau luv luv- qhov ua txhaum ntawm lub voj voog, cuam tshuam qhov cuam tshuam tam sim no, thiab rov qab kho lub zog sai sai los ntawm nws txoj haujlwm txuas rov qab, txo qis hluav taws xob poob.
Kev rwb thaiv tsev ua tau raws li cov qauv siab rau siab- cov khoom siv hluav taws xob, nrog lub zog ntsuas hluav taws xob- zaus tiv taus qhov hluav taws xob ntawm 70 kV thoob plaws qhov sib chwv thiab cov ntsuas hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob ntawm 170 kV theem- mus rau - av thiab theem - mus rau -theem. Qhov tsawg kawg nkaus sab nraud creepage nrug yog 31 mm / kV, ua rau cov khoom siv tiv thaiv kab sib chaws overvoltage surges thiab hnyav ib puag ncig xws li kub, high humidity, thiab plua plav, yog li ua kom ntev - haujlwm ruaj khov.
Kev tsim qauv ua haujlwm sib npaug kev nyab xeeb thiab yooj yim, ua raws li kev ua haujlwm tshawb fawb ntawm "O-0.5 s-CO-2 s-CO-5 s-CO." Cov kev ua haujlwm tau sib koom ua ke thiab meej, thiab cov khoom siv sib cuam tshuam thiab cov txee ua haujlwm cuam tshuam nrog kev tuav phau ntawv txhawm rau txhim kho kev ua haujlwm nyab xeeb thaum tso cai rau cov neeg ua haujlwm saib xyuas cov khoom siv hauv lub sijhawm.
Interlock hom Recloser yog dav siv nyob rau hauv siab -voltage distribution network upgrades, loj-scale ntse substation tsim, siab-voltage fais fab faib systems nyob rau hauv industrial parks, daim phiaj{3}}kev twb kev txuas tej yaam num rau tshiab zog fais fab nroj tsuag, thiab ntev- fais fab kis tej yaam num. Lawv ua tau raws li qhov tseem ceeb ntawm kev tiv thaiv thiab kev tswj cov kev xav tau ntawm siab -voltage fais fab system thaum ua raws li kev txhim kho ntawm cov kab hluav taws xob ntse automation thiab kev nyab xeeb, tso lub hauv paus ruaj khov rau kev ua haujlwm tsis tu ncua, ua haujlwm zoo, thiab muaj kev nyab xeeb ntawm lub zog hluav taws xob.
