大家了解真空饋電開關(guān)嗎，您知道真空虧電開關(guān)怎么使用嗎？下面我來(lái)為大家介紹真空饋電開關(guān)。
  KBZ-200/1140礦用隔爆型智能真空饋電開關(guān)，適用于煤礦井下，在交流50Hz，電壓為1140V或660V、電流至200A的中性點(diǎn)不接地三相電網(wǎng)中，具有欠壓、過(guò)載、短路、漏電閉鎖、漏電保護(hù)、選擇性漏電保護(hù)功能，并可外接遠(yuǎn)方分勵(lì)按鈕，用作總開關(guān)或分支開關(guān)，并具有風(fēng)電、瓦斯閉鎖功能。  KBZ-200真空饋電啟動(dòng)器技術(shù)數(shù)據(jù)
