Khoom Description
Lub 27kV Load Break Switch muaj lub neej txhua yam tsis pub tsawg dua 10,000 kev ua haujlwm thiab lub neej ua haujlwm tam sim no tsawg kawg yog 500 kev ua haujlwm, ua tau raws li qhov yuav tsum tau ua kom ntev -lub sijhawm thiab nquag ua haujlwm hauv qhov chaw sab nraum zoov. Nws yog yoog tau rau ntau yam kev ua haujlwm sab nraum zoov thiab tuaj yeem tswj xyuas kev ua haujlwm ruaj khov hauv ib puag ncig uas muaj qhov kub thiab txias, av noo, plua plav, nag, thiab daus, ua kom pom muaj zog ib puag ncig adaptability thiab durability.
Hais txog kev ua haujlwm ntawm kev ua haujlwm, cov khoom lag luam yog qhov tseeb thiab ua haujlwm tau zoo. Kev kaw thiab qhib tib lub sijhawm yog tswj tsis pub dhau tsawg dua lossis sib npaug li 2 ms, kev sib cuag bounce tsawg dua lossis sib npaug li 3 ms, lub sijhawm kaw tsawg dua lossis sib npaug li 60 ms, thiab lub sijhawm qhib tsawg dua lossis sib npaug li 40 ms. Nws cov lus teb ceev ceev thiab zoo heev synchronization xyuas kom du thiab txhim khu kev qha thauj khoom tam sim no hloov, ua kom tsis txhob muaj hluav taws xob thaum lub sijhawm ua haujlwm.
Kev rwb thaiv tsev ua tau raws li cov qauv kev lag luam siab, nrog rau 1-feeb feeb- zaus tiv thaiv hluav taws xob (RMS) ntawm 60 kV rau kev sib cuag, theem- rau-theem, thiab theem- rau hauv av, thiab xob laim impulse withstand voltage (ncej) ntawm 150 kV rau tib txoj kev.
Kev tso tawm ib nrab yog tsawg dua lossis sib npaug li 10 pC ntawm qhov ntsuas hluav taws xob ntawm 1.2Ur / √3, ua kom qhov kev hloov pauv kom tiv thaiv kab sib chaws overvoltage surges thiab ib feem cuam tshuam kev cuam tshuam, yog li ua kom muaj kev nyab xeeb ntawm rwb thaiv tsev thiab kev ua haujlwm ruaj khov.
Nrog rau qhov ntsuas tam sim no ntawm 630 A, 27kV Load Break Switch yog tsim rau cov qauv siv hluav taws xob sib kis tau zoo hauv nruab nrab - thiab siab -voltage tis networks. Nws yog dav siv nyob rau hauv nroog faib network segmentation thiab cais, industrial park faib ceg tswj, nyob deb nroog fais fab kev sib cais cais, txhawb tis systems rau tshiab zog fais fab chaw nres tsheb, thiab sab nraum zoov substation daim ntaub ntawv. Lub tshuab hluav taws xob tuaj yeem ua haujlwm hauv kev sib koom tes nrog cov hluav taws xob hluav taws xob kom ua tiav cov txheej txheem kev tiv thaiv hluav taws xob, lossis nws tus kheej ua cov khoom hloov tam sim no thiab kev sib cais txhaum, muab lub hauv paus ruaj khov rau kev nyab xeeb, tsis tu ncua, thiab ua haujlwm zoo ntawm lub zog hluav taws xob.
