SPD backup omukuumi T1 series
Okulambika kw’ebintu
Okusinziira ku mutindo gwa GB18802.1, GB50057 ne Q/THQBOO1-2013, enkomerero y’omu maaso eya SPD loop erina okuyungibwa mu lunyiriri n’ebyuma ebikuuma amasannyalaze agasukkiridde ebyetaagisa omukozi w’ekiziyiza okuwuuma.
Olw’okuba fiyuzi ya kasasiro ne miniature circuit breaker tebisobola kukwatagana na SPD, amasannyalaze bwe gaba agatali ga bulijjo oba SPD bw’eyonooneka n’egwa, omuliro n’ebyuma byonoonebwa okumyansa, ekikosezza ennyo enkola eya bulijjo ey’okufulumya!
Mu kiseera kino, omuwendo omunene ogwa miniature circuit breakers ezikozesebwa wamu ne SPD teguyinza kukwatagana mu nsonga zino ennya:
1.The lightning current shock kyangu nnyo okwonoona-okukuuma okumyansa kulemererwa;
2.High residual voltage ya lightning impulse current-okwesigamizibwa kw'okukuuma okumyansa kw'ebyuma kukendeera;
3.The power frequency free-wheeling tegwa-amaanyi agaweebwa si ga bulijjo ate SPD eri ku muliro;
4.The lightning impact trips by mistake-okukuuma okumyansa kulemererwa.
Okusinziira ku mbeera eriwo kati nti tewali kyuma kya SPD-specific supporting overcurrent protection makolero mu makolero agakuuma omulabe, oluvannyuma lw’emyaka esatu egy’okunoonyereza n’okukulaakulanya n’okusoba mu mwaka gumu ogw’okugezesa okw’enjawulo okw’okukoppa obutonde mu laboratory, kikakasibwa nti SPD backup protector (SCB)
1.SPD amaanyi frequency freewheeling olugendo omuwendo 4A
2.Non-trip impulse current esinga 40kA (8/20);
3.Lightning impulse ebisigadde okunyigirizibwa. Okugonjoola ddala embeera eriwo nti SPD terina byuma bya njawulo bikuuma ebisukkiridde ku kasasiro; Ekiva butereevu mu nkolagana wakati wa SCB ne SPD kwe kulaba nga SPD tekwata muliro ate ng’okukosebwa kw’amasannyalaze g’omulabe tekugwa.
Omulimu n’obunene bw’okukozesebwa
SPD special external disconnector eyungibwa mu series ku SPD loop, era munda current sorting channel ekyuma kikozesebwa okutegeera amaanyi frequency small current quick break; Okukuba kw’omulabe ow’amasannyalaze amangi tekugwa. Okutuuka ku mulimu gw’amaanyi frequency small current SPD okukuuma omuliro n’okukosebwa kw’omulabe SPD okukuuma obutasalako; Ebintu bya SCB bikozesebwa byokka ku SPD loop overcurrent protection, oba backup current okukuuma. Nsaba temuzikozesa ku mikolo emirala.
Ekintu ekikolebwa mu bikozesebwas
1. Parameter-controlled tripping mechanism, esobola okutegeera okulonda okumenya okuyita mu current;
2. Voltage esigaddewo eya impulse current eri wansi, eyinza okugeraageranyizibwa ku ya fiyuzi;
3. Okukwatagana okw’amaanyi amangi, nga kulina obulamu obuwanvu obw’okuweereza;
4. Micro-menyese ekifaananyi, obuzito obutono, kirungi okulemererwa amasannyalaze okuzuula SPD;
5.Complete specifications, okutuukiriza ebisaanyizo by'okuwagira SPD ku T1, T2 ne T3 levels.
Okuteeka eggaali y’omukka eya 6.35mm clamp rail kutuukiriza ebyetaago by’okussaako mu nsi yonna.
