Kev faib tawm ntawm cov khoom siv tiv thaiv xob laim.

Muaj ntau homcov khoom siv hluav taws xob, suav nrog cov khoom ntes hlau oxide, cov khoom ntes hlau oxide kab, cov khoom ntes hlau oxide kab tsis muaj qhov sib txawv, cov khoom ntes hlau oxide tsho tiv thaiv uas muaj rwb thaiv tsev tag nrho, thiab cov khoom ntes uas tshem tau.

Cov hom arresters tseem ceeb yog tubular arresters, valve arresters thiabcov khoom siv zinc oxideLub hauv paus ntsiab lus ua haujlwm tseem ceeb ntawm txhua hom xob laim ntes yog txawv, tab sis lawv lub ntsiab lus ua haujlwm yog tib yam, txhua yam los tiv thaiv cov xov hlau sib txuas lus thiab cov khoom siv sib txuas lus los ntawm kev puas tsuaj.

Cov cuab yeej ntes raj
Lub raj xa hluav taws xob no yog ib qho chaw tiv thaiv uas muaj peev xwm tua hluav taws xob ntau. Nws muaj ob qhov chaw sib txuas. Ib qho chaw nyob hauv huab cua, hu ua qhov chaw sab nraud. Nws txoj haujlwm yog cais lub zog hluav taws xob ua haujlwm thiab tiv thaiv cov yeeb nkab tsim roj kom tsis txhob ntws los ntawm cov yeeb nkab. Qhov thib ob raug hlawv los ntawm cov hluav taws xob xau; lwm qhov raug teeb tsa rau hauv cov yeeb nkab cua thiab hu ua qhov chaw sab hauv lossis qhov chaw tua hluav taws xob arc. Lub peev xwm tua hluav taws xob arc ntawm lub raj xa hluav taws xob muaj feem cuam tshuam nrog qhov loj ntawm cov hluav taws xob zaus txuas ntxiv mus. Qhov no yog qhov chaw tiv thaiv hluav taws xob, uas feem ntau siv rau kev tiv thaiv hluav taws xob ntawm cov kab hluav taws xob.

Lub valve hom arrester
Lub valve homtus ntesNws muaj ib qho chaw hluav taws xob thiab ib lub phaj valve resistor. Cov khoom siv ntawm lub phaj valve resistor yog silicon carbide tshwj xeeb. Lub valve chip resistor ua los ntawm silicon carbide tuaj yeem tiv thaiv xob laim thiab hluav taws xob siab, thiab tiv thaiv cov khoom siv. Thaum muaj hluav taws xob siab, qhov chaw hluav taws xob tawg, qhov tsis kam ntawm lub phaj valve poob qis, thiab hluav taws xob tam sim no nkag mus rau hauv av, uas tiv thaiv cov xov hlau lossis cov khoom siv hluav taws xob los ntawm kev puas tsuaj ntawm hluav taws xob tam sim no. Nyob rau hauv qhov xwm txheej ib txwm muaj, qhov chaw hluav taws xob yuav tsis tawg, thiab qhov tsis kam ntawm lub phaj valve resistor siab, uas yuav tsis cuam tshuam rau kev sib txuas lus ib txwm ntawm kab sib txuas lus.

Cov khoom siv tiv thaiv zinc oxide
Zinc oxide xob laim arresteryog lub cuab yeej tiv thaiv xob laim nrog kev ua tau zoo tshaj plaws, lub teeb yuag, tiv taus kev ua qias tuaj thiab kev ua haujlwm ruaj khov. Nws feem ntau siv cov yam ntxwv zoo non-linear volt-ampere ntawm zinc oxide los ua kom tam sim no ntws los ntawm lub arrester me me heev (microamp lossis milliampere theem) ntawm qhov hluav taws xob ua haujlwm ib txwm muaj; thaum lub overvoltage ua haujlwm, qhov kev tiv thaiv poob qis, tso pa tawm lub zog overvoltage kom ua tiav cov txiaj ntsig ntawm kev tiv thaiv. Qhov sib txawv ntawm hom arrester no thiab cov arrester ib txwm muaj yog tias nws tsis muaj qhov sib txawv thiab siv cov yam ntxwv tsis-linear ntawm zinc oxide los tso tawm thiab tawg.

Ob pebcov khoom siv hluav taws xobtau qhia saum toj no. Txhua hom arrester muaj nws tus kheej qhov zoo thiab cov yam ntxwv. Nws yuav tsum tau siv rau hauv ntau qhov chaw sib txawv kom ua tiav qhov kev tiv thaiv xob laim zoo.
