220A DC odklopnik opravi eno nalogo, ki je va\u0161 BMS sam ne more: zagotovi fizi\u010dni prekinitev v vezju.<\/strong> Va\u0161 BMS \u0161\u010diti celice pred prekomernim tokom in kratkimi stiki, vendar ko morate delati na paketu, izolirati inverter ali izklopiti napajanje v sili, potrebujete nekaj, kar lahko dejansko izklopite. Ta 2-polni DC odklopnik sedi med va\u0161o baterijo in inverterjem, doda za\u0161\u010dito pred kratkim stikom poleg BMS in vam daje vidno to\u010dko za odklop.<\/p>

Zakaj 220A DC odklopnik presega zana\u0161anje samo na BMS<\/h3>

BMS je za\u0161\u010ditna naprava, ne stikalo. Prekine tok, ko nekaj ni v redu, vendar vam ne omogo\u010da, da po potrebi izolirate paket \u2014 in ne bo odpravil trdega kratkega stika na glavni DC napajalni liniji tako kot odklopnik. Dodajanje odklopnika vam prinese tri stvari, ki jih BMS sam ne more:<\/p>

  • Ro\u010dni odklop<\/strong> za vzdr\u017eevanje, nadgradnje in nujne primere<\/li>
  • Odpravljanje kratkega stika<\/strong> ocenjeno na 7,5kA<\/li>
  • Napaka, ki jo lahko vidite<\/strong> \u2014 spro\u017een odklopnik vam poka\u017ee, da se je nekaj zgodilo, namesto da bi vas pustil ugibati<\/li><\/ul>

    AC odklopniki ne sodijo v baterijsko vezje<\/h4>

    To je najve\u010dja napaka. Izmeni\u010dni tok prehaja skozi ni\u010dlo 50-60 krat na sekundo, in ta ni\u010delni prehod omogo\u010da AC odklopniku, da ugasne oblok, ko se spro\u017ei. Enosmerni tok nima ni\u010delnega prehoda, zato oblok \u0161e naprej gori. AC odklopnik lahko ne uspe odpraviti napake v baterijskem sistemu, kar je prav situacija, ki jo mora odklopnik re\u0161iti.<\/p>

    Kaj pomeni ocena 220A v praksi<\/h3>

    Najpogostej\u0161a konfiguracija v DIY skladi\u0161\u010dnem paketu je 200A BMS. Ta odklopnik je ocenjen na 220A, korak vi\u0161je, kar vam daje rezervo za za\u010detni tok brez prevelike velikosti naprave ali kabla.<\/p>

    Ena pravila, ki \u0161tejejo bolj kot tabela: nikoli ne namestite odklopnika z oceno pod stalnim tokom va\u0161ega sistema in nikoli ne namestite kabla z oceno pod odklopnikom.<\/p>

    Fitting a DC Circuit Breaker Into a DIY Battery Box<\/h3>

    At 78 \u00d7 38 \u00d7 63mm and 225g, this breaker fits inside a battery enclosure or a tight cabinet instead of needing its own panel.<\/p>

    1. Mount it where you can reach it.<\/strong> A breaker you cannot access is decoration.<\/li>
    2. Follow the LINE and LOAD markings<\/strong>, and confirm the wiring diagram in the manual before connecting.<\/li>
    3. Torque the terminals to spec<\/strong> and re-check after the first thermal cycle.<\/li>
    4. Keep AC and DC separate.<\/strong> This device goes on the DC side between battery and inverter.<\/li>
    5. Leave room for the cables.<\/strong> Thick DC cable needs bend radius.<\/li><\/ol>
