Mtetezi woteteza wa SPD T1 mndandanda
Chidule cha malonda
Malinga ndi miyezo ya GB18802.1, GB50057 ndi Q/THQBOO1-2013, mbali yakutsogolo ya lupu ya SPD iyenera kulumikizidwa motsatizana ndi zida zotetezera mphamvu zamagetsi zomwe wopanga chitetezo cha surge amafunikira.
Popeza fuse ndi miniature circuit breaker sizingagwirizane ndi SPD, pamene magetsi sakuyenda bwino kapena SPD ikawonongeka ndikulephera kugwira ntchito, moto ndi zida zimawonongeka ndi mphezi, zomwe zakhudza kwambiri ntchito yabwinobwino yopangira!
Pakadali pano, ma miniature circuit breakers ambiri omwe amagwiritsidwa ntchito limodzi ndi SPD sangafanane ndi mfundo zinayi izi:
1. Kugwedezeka kwa mphamvu ya mphezi n'kosavuta kuwononga - chitetezo cha mphezi chimalephera;
2. Mphamvu yotsalira yamagetsi yamagetsi - kudalirika kwa chitetezo cha mphezi pazida kumachepa;
3. Kuthamanga kwa mphamvu kosalekeza sikumagunda - magetsi sakuyenda bwino ndipo SPD ikuyaka;
4. Kugundana kwa mphezi kumadutsa molakwika - chitetezo cha mphezi chimalephera.
Poganizira momwe zinthu zilili panopa kuti palibe chipangizo choteteza mphamvu yamagetsi chothandizira pamagetsi cha SPD m'makampani oteteza mphezi, patatha zaka zitatu za kafukufuku ndi chitukuko komanso zaka zoposa chimodzi zoyeserera zachilengedwe mu labotale, zatsimikiziridwa kuti chitetezo chosungira cha SPD (SCB) ndi chothandiza kwambiri.
1. Mtengo wa ulendo wa SPD frequency freewheeling trip 4A
2. Mphamvu yamagetsi yosayenda ndi yayikulu kuposa 40kA (8/20);
3. Kuchepetsa mphamvu yamagetsi. Kuthetsa vuto lomwe lilipo pano kuti SPD ilibe zida zapadera zotetezera mphamvu yamagetsi; Zotsatira za mgwirizano pakati pa SCB ndi SPD ndikuwonetsetsa kuti SPD sigwira moto ndipo mphamvu yamagetsi yamagetsi siikugwa.
Ntchito ndi kuchuluka kwa ntchito
Cholumikizira chapadera chakunja cha SPD chimalumikizidwa motsatizana pa SPD loop, ndipo chipangizo chosinthira chamkati chamagetsi chimagwiritsidwa ntchito kuti chizimitsa magetsi pang'ono mwachangu; Mphamvu yamagetsi yayikulu siyimagunda. Kukwaniritsa ntchito ya mphamvu yamagetsi yaying'ono chitetezo cha moto cha SPD ndi mphamvu yamagetsi chitetezo cha SPD chosalekeza; Zogulitsa za SCB zimagwiritsidwa ntchito poteteza magetsi pang'onopang'ono a SPD loop, kapena chitetezo chamagetsi chosungira. Chonde musagwiritse ntchito nthawi zina.
Mbali ya malondas
1. Njira yoyendetsera zinthu yoyendetsedwa ndi magawo, yomwe imatha kuzindikira kuswa kwamagetsi kosankha;
2. Mphamvu yotsalira ya mphamvu ya impulse ndi yotsika, yomwe ingafanane ndi ya fuse;
3. Kulumikizana ndi mphamvu zambiri, ndi moyo wautali wautumiki;
4. Kapangidwe kakang'ono kosweka, voliyumu yaying'ono, kothandiza kuti mphamvu ilephere kuzindikira SPD;
5. Kukwaniritsa zofunikira zonse, kukwaniritsa zofunikira zothandizira SPD pamlingo wa T1, T2 ndi T3.
Kukhazikitsa njanji ya clamp ya 6.35mm kukukwaniritsa zosowa za kukhazikitsa padziko lonse lapansi.
