我局为了确保通讯,试制了一部可控硅逆变器.以往当交流市电停电之后,为了不中断对电传打字机及会议电话机等小容量负荷的供电,靠开自备柴油发电机供电.由于柴油机容量较大,开机要十多分钟的启动时间.同时,维护油机要占用一个值机人员,尤其在晚上一人值班,突然停电更感困难,而且晚间仅对一部电传机供电也很不经济.我们拟使用直流变交流的逆变器,在停电后可立即开机供电,甚至可以做到自动转换供电.因此,我们提出做一部用蓄电池供电的可控硅逆变器,以便在市电停电后对小容量负荷供给220V交流电.
In order to ensure communication, our bureau tried a thyristor inverter. In the past, when AC power was cut off, in order not to interrupt the supply of small-capacity loads such as teletypewriters and conference phones, Power supply.Because diesel engine capacity is bigger, boot to more than ten minutes of start-up time.At the same time, maintenance of the oil machine to occupy a check-in personnel, especially at night one person on duty, sudden power outages more difficult, and only a teleconverter at night Power supply is also very uneconomical.We intend to use the DC to AC inverter, power can immediately boot after power supply, and even can be automatically converted to power supply.Therefore, we proposed to do a battery-powered SCR inverter , In order to supply 220V alternating current to the small-capacity load after the mains cut off.
