摘要
根据国家标准并参考IEC标准对控制电路的要求,通过对直接启动的一用一备、两用一备湿式消防灭火系统喷淋泵控制电路的讨论,探讨目前广泛应用的控制电路可靠性和经济性的提升。
Discussion about directly started wet type fire fighting system spray pumps in a one‑in‑use,one‑backup mode or a two‑in‑use,one‑backup mode is done in accordance with the applicable national standards and IEC standard to find out ways to promote reliability and cost efficiency of the currently widely used control circuits.
