Umgaqo wokhuseleko lokugqithiswa kwamandla izixhobo zokucima rhoqo

Umlinganiselo wokukhusela ukugqithisa kukusebenzisa i-varistor ngokuhambelana neziphelo ezimbini zombane wombane. I-varistor inomdla kakhulu kumbane. Xa i-voltage idlula ixabiso elithile, ixabiso layo lokumelana ngokukhawuleza liba lincinci, ukwenzela ukuba i-current inyuke ngokukhawuleza. Xa isixhobo sine-overvoltage, siya kudiliza i-varistor, ukwenzela ukuba zombini iziphelo zonikezelo lwamandla ziya kunqunyulwa, ngaloo ndlela zikhusele umva wokunikezelwa kwamandla kunye nokuphepha umngcipheko wokugqithisa, osebenzela injongo yokukhusela umbane. Ngethuba nje i-varistor iguqulwa rhoqo, izixhobo zinokusetyenziswa ngokuqhelekileyo, kodwa kufuneka sitshintshe i-varistor ngexesha, elinzima ukusebenza. Ukuba ayinakutshintshwa ngexesha, isiphaluka sesixhobo sinokonakala, kwaye nokuba nomlilo unokuvela kwiimeko ezinzima.

Ukukhuselwa kwe-overvoltage kunye nokukhuselwa kwe-undervoltage yezixhobo zokucima i-high-frequency kubaluleke kakhulu. Ngethuba nje ixabiso le-voltage yezixhobo zethu lidlula umda, ukukhanya kwesalathisi kwisixhobo kuya kukhanya kwaye i-alamu iya kukhutshwa ngokuzenzekelayo. Ngeli xesha, abasebenzi kufuneka bathathe amanyathelo ngokukhawuleza ukuphepha Imeko yamacandelo angcono iphinda ithintele ukwenzeka kweengxaki ezifana nomlilo. Ikhuselekile kwaye iyasebenza.
