由于大功率家电诸如空调、电暖器、电热水器等电器用电量的骤增,原有的用电网又很难全面增容,因而低电压现象极为普遍。当电压低至180伏以下时,日光灯不易启辉,且有损灯管寿命。严格地讲,低电压现象应属供电质量问题,这一现象短期内很难解决。虽然市场上已有低压启辉器问世,但优劣混杂,价格不便宜,且属小商品,一般商店又不愿经营。
As the high-power appliances such as air conditioners, heaters, electric water heaters and other electrical power surge, the original power grid is difficult to full capacity, and thus the phenomenon of low voltage is extremely common. When the voltage is as low as 180 volts, fluorescent lamp is not easy to start, and detrimental to lamp life. Strictly speaking, the phenomenon of low voltage power quality should be a problem, this phenomenon is difficult to solve in the short term. Although the market has been available low-voltage starter, but the pros and cons, the price is not cheap, and is a commodity, the general store and unwilling to operate.
