Kev daws teeb meem rau cov tsev.

Surges - ib tug underestimated txaus ntshaiSurges yog ib qho kev pheej hmoo tsawg tsawg. Cov voltage pulses (transients) uas tsuas yog siv sij hawm sib cais thib ob yog tshwm sim los ntawm ncaj qha, nyob ze thiab tej thaj chaw deb xob laim tawm tsam lossis hloov kev ua haujlwm ntawm cov khoom siv hluav taws xob.xob laim ncaj nraim thiab nyob ze Cov hluav taws xob ncaj nraim los yog nyob ze yog xob laim tawm hauv lub tsev, nyob ze ze lossis hauv cov kab nkag mus rau hauv lub tsev (xws li hluav taws xob qis hluav taws xob, kev sib txuas lus thiab cov ntaub ntawv kab). Lub amplitude thiab lub zog cov ntsiab lus ntawm lub resulting impulse tam sim no thiab impulse voltages raws li zoo raws li txuam electromagnetic teb (LEMP) considerably hem lub system kom tiv thaiv. Cov hluav taws xob tam sim no uas tshwm sim los ntawm hluav taws xob ncaj qha mus rau hauv ib lub tsev ua rau muaj peev xwm nce ntau ntawm 100,000 volts ntawm tag nrho cov khoom siv hauv av. Surges yog tshwm sim los ntawm qhov hluav taws xob poob ntawm cov pa hauv av impedance thiab qhov tshwm sim muaj peev xwm sawv ntawm lub tsev nrog kev hwm rau ib puag ncig. Qhov no yog qhov kev ntxhov siab tshaj plaws ntawm cov tshuab hluav taws xob hauv cov tsev. Nyob rau hauv tas li ntawd mus rau lub voltage poob ntawm cov pa earthing impedance, surges tshwm sim nyob rau hauv lub hluav taws xob installation ntawm lub tsev thiab nyob rau hauv cov kev sib txuas systems thiab pab kiag li lawm vim lub induction nyhuv ntawm lub xob laim electromagnetic teb. Lub zog ntawm cov induced surges thiab qhov tshwm sim impulse tam sim no qis dua ntawm cov hluav taws xob ncaj qha impulse tam sim no. Tej thaj chaw deb xob laim Tej thaj chaw deb xob laim are lightning strikes far away from the object to be protected, in the medium-voltage overhead line network or in its close proximity as well as cloud-to-cloud discharge. Hloov kev ua haujlwm Hloov kev ua haujlwm of power utilities cause surges (SEMP - Switching Electromagnetic Pulse) of some 1,000 volts in electrical systems. They occur, for example, when inductive loads (e.g. transformers, reactors, motors) are switched off, arcs are ignited or fuses trip. If power supply and data lines are installed in parallel, sensitive systems may be interfered with or destroyed. Kev tiv thaiv kev siv hluav taws xob thiab cov ntaub ntawv kaw lus Kev puas tsuaj nyob rau hauv thaj chaw, chaw ua haujlwm thiab kev tswj hwm vaj tse thiab cov chaw tsim khoom lag luam yuav tshwm sim hauv, piv txwv li, cov khoom siv hluav taws xob, cov ntaub ntawv thev naus laus zis thiab xov tooj, kev tswj hwm ntawm cov chaw tsim khoom los ntawm cov chaw nres tsheb thiab cov tswj cov cua txias lossis teeb pom kev zoo. . Cov txheej txheem rhiab heev no tsuas tuaj yeem tiv thaiv los ntawm lub tswv yim kev tiv thaiv zoo. Hauv cov ntsiab lus no, kev sib koom tes siv cov cuab yeej tiv thaiv hluav taws xob (tam sim no xob laim thiab surge arresters) yog qhov tseem ceeb. Lub luag haujlwm ntawm xob laim tam sim no ntes yog tso tawm lub zog siab yam tsis muaj kev puas tsuaj. Lawv raug ntsia kom ze li sai tau mus rau qhov chaw uas cov hluav taws xob nkag mus rau hauv lub tsev. Surge arresters, nyob rau hauv lem, tiv thaiv cov khoom siv davhlau ya nyob twg. Lawv raug ntsia kom ze li sai tau rau cov khoom siv tiv thaiv. Nrog nws cov khoom siv liab / kab hauv tsev rau cov khoom siv hluav taws xob thiab nws tsev neeg cov khoom siv daj / kab rau cov ntaub ntawv, THOR muaj cov khoom siv tiv thaiv kev sib haum xeeb. Modular portfolio tso cai rau tus nqi-optimized siv cov tswv yim tiv thaiv rau txhua hom tsev thiab qhov ntau thiab tsawg.
