JL-207C Photocontrol Zero-Cross Protection Technology

Itekhnoloji yokukhusela i-Voltage zero-crossing protection, ukwenzela ukukhusela i-relay kwimveliso.

Indlela yokuqonda ukukhuselwa kukuba: ukunikezelwa kwamandla kwi-coil relay ilawulwa yi-microcomputer ye-single-chip, ngaloo ndlela ilawula ukuvala abafowunelwa be-relay.Kwangaxeshanye, indawo yokuqalisa iyenzeka ibe yindawo yombane onguziro we-AC sine wave.Abafowunelwa be-relay bavaliwe kufuphi nendawo yombane we-zero, enokunciphisa i-arcing yabafowunelwa, ngaloo ndlela ikhusela i-relay kwimpembelelo yemisinga emikhulu.

Iingcebiso zoMfanekiso

Umgca oblowu- iliza yesine yomsinga otshintshanayo

Umgca otyheli-indawo yokuqalisa ukuvala unxibelelwano lwe-relay

I-1-1 Inqaku le-trigger likummandla we-zero-voltage

I-1-2 i-Trigger point itenxa kwi-voltage engu-0

Ukuqukumbela

I-1-1 Kufuphi ne-trigger point kunye ne-voltage ye-zero, xa uqhagamshelwano luvaliwe, ukulahlekelwa komzimba we-relay's instantaneous current excessive current kungaphetshwa.

I-1-2 Xa umnxeba uvaliwe, kukho i-arc evela kwi-voltage ye-zero, ngoko xa umnxeba uvaliwe, akukho khuselo lokubuyisela.

Uthotho lwethu olunxulumene neVoltage zero-cross yemveliso yokhuseleko:207C, 207HP, 207E,207F, 205C, 215C, 243C,217C, 251C, njl.
