Bayanan

DC MCCB (DC Molded Case Circuit Breaker) na naman daga da ya tsohon rawarwa da kontrola da aka fadada don cikin abubuwan DC power. Ana amfani da tsarin packaging da kuma shiga mai kyau da aka dogara da jamiyar current detection, fault judgment, da kuma instantaneous breaking. Tsarin da take da shi shine in yin gina da adalci a kan electrical energy a cikin abubuwan DC power distribution circuits, inda ya yi tabbacin da kuma kawo hankali da kisan faults kamar overload, short circuit, da kuma undervoltage a cikin circuit. Wannan ya taimaka wajen samun sarrafa da kasa da abubuwan DC power supplies, power distribution equipment, da kuma downstream loads (kamar energy storage systems, photovoltaic inverters, DC motors, da sauransu), kuma ya zama muhimmin yanayi don in tabbatar da duk da cewa ana yi waƙo da kasa da adalci a kan abubuwan DC power systems.

Abubuwan

• Mai Kyau da DC Breaking Capacity: Aka yi da wannan bayan da "difficult arc extinction" na iya haɗa a cikin abubuwan DC, ana amfani da sabbin DC arc-extinguishing system (kamar multi-slit arc-extinguishing chamber da kuma magnetic blow device). An san Ics (rated short-circuit breaking capacity) a matsayin kadan da kadan da kiloamperes (misali, 50KA~100KA, ta hanyar model), wanda zai iya kawo hankali da kisan fault arcs da kuma tabbatar da breaking reliability.

• Accurate Fault Protection: Ana amfani da abubuwan protection kamar overload long-time delay, short circuit short-time delay, instantaneous short circuit, da kuma undervoltage protection. Ana iya set protection parameters da kuma taimakawa da rated current da kuma load characteristics na abubuwan DC, don in tabbatar da duk da cewa an yi waƙo da kasa a kan abubuwan DC power distribution scenarios na different power levels.

• Wide Voltage and Current Adaptability: An samu voltage level da ya kusa DC 24V~1500V (da za su iya amfani a low-voltage da medium-voltage DC systems), da kuma rated current range da ya kusa dari tens of amperes to several hundreds of amperes (misali, 63A~630A). Zan iya tabbatar da duk da cewa ana yi waƙo da kasa a kan abubuwan power distribution na different scenarios kamar energy storage power stations, data center UPS, da kuma photovoltaic DC combiner boxes.

• High Environmental Adaptability: Ana amfani da insulating materials da ke da takardukar high and low temperature, anti-aging, da kuma sealed structure. An samu operating temperature range da ya kusa -30℃~+70℃, da kuma ya ke da dustproof da moisture-proof performance (wasu models suna da IP40 protection level), kuma zan iya tabbatar da duk da cewa ana yi waƙo da kasa a kan abubuwan complex environments kamar outdoors, computer rooms, da kuma industrial workshops.
