Kuchepetsa kusungunula zida zamoto: shunt

Shunt: amagwiritsidwa ntchito kuwonetsa DC pano, yolumikizidwa ndi ammeter kuti iwonetsedwe

Cholinga: Khazikika lokhazikika shunt ndi shunt yakunja yoyenera kuyerekezera DC pano pansi pa 10kA ndikuchita molunjika pazida zowonetsera analog kuti ikukulitse muyeso wa DC wapano, kapena itha kuwonedwa ngati pakadali pano motsatana. standard resistor yomwe imagwiritsidwa ntchito pakuwerengera imatha kuonedwa ngati chizindikiro cha analog chamakono oyambira omwe amagwiritsidwa ntchito poyesa.

Mfundo zazikulu zamakono

1. Zowona kalasi: 2 ～ 4000A; 0.5 kalasi: 5000 ～ 10000A; Kalasi imodzi.

Zinthu zachilengedwe: -2 ～ + 40 ℃, kutentha pang’ono ≤60% (95 ℃).

3. Kuchita zambiri: 120% yamavotedwe apano, maola 2.

4. Kutsika kwa Voltage: 50mV60mV70mV100mV

5. Kutentha pakatundu: Kutentha kukangokhala kolimba, zomwe zidavotera pansipa 50A sizipitilira 80 ° C; Zomwe zidavoteledwa pamwambapa 50A sizipitilira 120 ° C.

Chithunzithunzi cha waya wa shunt

CHENJEZO

1. Palibe kukana kophatikizana komwe kumaloledwa pamalumikizidwe pakati pa chingwe (kapena bala yamkuwa) yoyendera yoyambira ya shunt ndi shunt. Ma sampling amagetsi achiwiri sangasankhidwe kuchokera pamalo osakhala ochepa.

2. Ndikulimbikitsidwa kuti makono omwe agwiritsidwa ntchito (kwa nthawi yayitali) asapitirire 80% yazomwe zidavoteledwa.
