Indima yomkhuseli wotyando

I-Surge, (Isixhobo sokukhusela i-Surge) sisixhobo esiyimfuneko ekukhuseleni umbane wezixhobo zombane.Umsebenzi womkhuseli wokutyanda kukunqanda umbane ogqithisayo ngokukhawuleza ongena kumgca wamandla kunye nomgca wokuhambisa umqondiso ngaphakathi koluhlu lwamandla ombane isixhobo okanye inkqubo enokumelana nayo, okanye ukukhupha umbane onamandla okhoyo emhlabeni ukukhusela izixhobo ezikhuselweyo okanye inkqubo. ekonakalisweni.zonakaliswe yimpembelelo.

Umgaqo womkhuseli weSurge

Umgaqo osebenzayo womkhuseli wokutya umi ngolu hlobo lulandelayo: umkhuseli wokutya ufakwe ngokubanzi kuzo zombini iziphelo zesixhobo esikhuselweyo kunye nesiseko.Phantsi kweemeko eziqhelekileyo zokusebenza, umkhuseli wokutyanda ubonisa ukukhuselwa okuphezulu kumbane oqhelekileyo wamandla ombane, kwaye phantse akukho nto ihamba ngayo ngoku, elingana nesekethe evulekileyo;xa i-overvoltage edlulayo isenzeka kwinkqubo, umkhuseli wokutya uya kusabela kwi-high-frequency transient overvoltages.I-voltage inikezela nge-impedance ephantsi, elingana nokujikeleza okufutshane kwizixhobo ezikhuselweyo.

1. Uhlobo lokutshintsha: Umgaqo wayo wokusebenza kukuba xa kungekho overvoltage ekhawulezileyo, inika i-impedance ephezulu, kodwa xa isabela kumbane ogqithisayo ngokukhawuleza, ukuxhatshazwa kwayo kutshintsha ngokukhawuleza kwixabiso eliphantsi, ukuvumela umbane wombane ukuba udlule.Xa zisetyenziswe njengezixhobo ezinjalo, izixhobo ziquka: izithuba zokukhupha, iibhubhu zokukhupha igesi, i-thyristors, njl.

2. Uhlobo lwe-Voltage-limiting type: Umgaqo wayo wokusebenza kukuba i-impedance ephezulu xa kungekho overvoltage ngokukhawuleza, kodwa i-impedance yayo iya kuqhubeka iyancipha ngokunyuka kwe-surge current kunye ne-voltage, kwaye i-voltage yangoku-i-voltage ibonakaliso kakhulu i-nonlinear.Izixhobo ezisetyenziselwa izixhobo ezinjalo zezi: zinc oxide, varistor, suppressor diode, avalanche diode, njl.

3. Shunt uhlobo okanye uhlobo lokuminxa

Uhlobo lwe-Shunt: ngokuhambelana nezixhobo ezikhuselweyo, zibonakalisa ukuthintela okuphantsi kwimibhobho yombane kunye ne-impedance ephezulu kumaza okusebenza aqhelekileyo.

Uhlobo lwe-Choke: Kuluhlu olunezixhobo ezikhuselweyo, zibonakalisa ukhuseleko oluphezulu kwimibhobho yombane kunye nokuphazamiseka okuphantsi kokusebenza okuqhelekileyo.

Izixhobo ezisetyenziswa njengezixhobo ezinjalo zibandakanya: iikhoyili eziminxayo, izihluzi ezigqithisayo, izihluzi ezisezantsi, i-1/4 ye-wavelength short-circuiters, kunye nokunye okunjalo.
