摘要
简述了过去老式双风机自动切换开关(或在磁力起动器中加装自制的转换装置)存在的隐患,QBZ-2×80/660(380)-SF矿用隔爆型风机用双电源真空电磁起动器的组成、工作原理和特点。
Has summarized the past old style double air blower automatic cut over switch (or installs the hidden danger which in magnetic starter self- made switching device) exists, QBZ -2 × 80/660 (380) - SF the mineral product flame - proof type air blower uses the double power source vacuum electromagnetism starter's composition, the principle of work and the characteristic.
