Optimization Design of Direct Air Cold Low Pressure in Coal-fired Power Plant Factory with the Power Secondary System

In the coal-rich and water-poor area, choosing the air-cooling system has become the dominant way to save water resources. There are many important electrical equipments in the air-cooling system, it is may malfunction or even cause an accident when these devices are operating. We must design the secondary electrical wiring rationally, so it can removal the fault quickly, accurate and reliably when the main of the electrical equipment malfunctioned. It makes the air-cooling system maintained in good working condition is very important. This article summarizes the experience of many years of engineering practice and details the design of the secondary electrical wiring of the air-cooling system.
