SPD Backup Mtetezi T2 mndandanda

Chidule cha mankhwala

Malinga ndi miyezo ya GB18802.1, GB50057 ndi Q/THQBOO1-2013, mapeto akutsogolo a SPD loop ayenera kulumikizidwa motsatizana ndi zida zodzitchinjiriza mopitilira muyeso zomwe zimafunidwa ndi wopanga zida zoteteza. SPD, pamene magetsi ndi osadziwika kapena SPD ikuwonongeka ndikulephera, moto ndi zipangizo zimawonongeka ndi mphezi, zomwe zakhudza kwambiri ntchito yachibadwa yopangira!

Pakalipano, oyendetsa madera ang'onoang'ono omwe amagwiritsidwa ntchito limodzi ndi SPD sangathe kufanana ndi mfundo zinayi zotsatirazi:

 

Poganizira momwe zinthu zilili pano kuti palibe chipangizo cha SPD chothandizira chitetezo champhamvu kwambiri pamakampani oteteza mphezi, patatha zaka zitatu za kafukufuku ndi chitukuko komanso kupitilira chaka chimodzi chazoyeserera zosiyanasiyana zoyeserera zachilengedwe mu labotale, zikutsimikiziridwa kuti chitetezo cha SPD. (SCB)

1.SPD mphamvu pafupipafupi freewheeling ulendo mtengo 4A

2.Non-trip impulse current ndi yaikulu kuposa 40kA(8/20);

3.Mphenzi impulse residual depression. Kuthetsa kwathunthu zomwe zikuchitika pano kuti SPD ilibe zida zapadera zodzitetezera; Zotsatira zachindunji za mgwirizano pakati pa SCB ndi SPD ndikuwonetsetsa kuti SPD sikugwira moto komanso mphezi zomwe zikuchitika pano sizikuyenda.

 

Ntchito ndi kuchuluka kwa application

 

SPD cholumikizira chakunja chapadera chimalumikizidwa pamndandanda wa SPD loop, ndipo chipangizo chamkati chosinthira chamkati chimagwiritsidwa ntchito kuzindikira ma frequency amagetsi ang'onoang'ono omwe akupumira mwachangu; Kuwomba kwamphezi sikudutsa. Kukwaniritsa ntchito ya mphamvu pafupipafupi yaing'ono pompano SPD chitetezo moto ndi mphezi zimakhudza SPD chitetezo mosalekeza; Zogulitsa za SCB zimagwiritsidwa ntchito poteteza SPD loop overcurrent, kapena chitetezo chapano. Chonde musagwiritse ntchito nthawi zina.

 

Zogulitsa

1. Njira yodutsamo yoyendetsedwa ndi parameter, yomwe imatha kuzindikira kuthyolako kosankha;

2. Mphamvu yotsalira ya mphamvu yamagetsi ndi yochepa, yomwe ingafanane ndi fuse;

3. Kulumikizana kwamphamvu kwambiri, ndi moyo wautali wautumiki;

4. Mawonekedwe ang'onoang'ono osweka, voliyumu yaying'ono, yabwino kulephera kwa mphamvu kuzindikira SPD;

5.Mafotokozedwe athunthu, kukwaniritsa zofunikira zothandizira SPD pamagulu a T1, T2 ndi T3.

Kuyika kwa 6.35mm clamp njanji kumakwaniritsa zofunikira padziko lonse lapansi.
