varistor na-arụ ọrụ dị mkpa na sekit.Mgbe overvoltage na-eme n'etiti ọkwa abụọ nke varistor, e nwere ike iji njirimara nke varistor mee ihe iji kpoo voltaji na uru voltaji dị ntakịrị, nke mere na iji gbochie voltaji na sekit, na-echebe sekit na-esote.
Yabụ ị maara ihe okwu ndị a: voltaji nominal, voltaji varistor, voltaji residual, nguzogide mkpuchi, ikike dị ugbu a, na leakage ugbu a pụtara maka varistors?Ọ bụrụ na ị maghị, gụọ akụkọ a ka ị mụta.
1. Nominal voltaji (V): A makwaara dị ka voltaji akara, na-ezo aka na voltaji uru gafee varistor mgbe a DC ugbu a nke 1m gafere.
2. Varistor voltaji: Ọnụ ego voltaji tụrụ na nsọtụ abụọ nke varistor mgbe otu ihe dị ugbu a (1mA DC) na-agafe na varistor.
3. Residual voltaji ruru: Mgbe ugbu a site na varistor bụ ụfọdụ uru, voltaji eme na nsọtụ abụọ nke varistor a na-akpọ residual voltaji nke ugbu a uru.Oke voltaji fọdụrụnụ bụ oke nke voltaji fọdụrụ na voltaji ọnụ.
4. Mgbochi mkpuchi: nguzogide DC nke insulator n'okpuru ọnọdụ akọwapụtara.Mgbochi mkpuchi nke varistor na-ezo aka uru nguzogide n'etiti waya ndu (pin) nke varistor na mkpuchi mkpuchi nke resistor.
5. Ikike ịgba ọsọ (kA): ọnụ ahịa kacha elu ugbu a na-ekwe ka ọ gafere site na varistor n'okpuru oge a kapịrị ọnụ na ọnụ ọgụgụ nke oge, n'okpuru ngwa nke ọkọlọtọ mkpali ugbu a.
6. Leakage current (mA): na-ezo aka na nke ugbu a na-agafe na varistor n'okpuru okpomọkụ a kapịrị ọnụ na oke DC voltaji.
