高炉炼铁工艺具有不问断连续生产的特点,电源的可靠性对保证不间断连续生产至关重要。电源系统因故障意外停电,可能会导致高炉喷铁渣,并烧损风口,或者因煤气压力升高而得不到快速泄压,从而引起煤气爆炸和泄漏等危害人身安全的恶性事故;另外,电源系统故障停电也会导致控制系统失去控制和监视,对迅速发现故障点并及时开展应急处理和施救造成阻碍,还会对事故的后续分析和查明事故原因造成不利影响。因此,提高供配电系统供电的可靠性,是高炉炼铁工程电气设
Blast furnace ironmaking process has the characteristics of continuous production without interruption, the reliability of the power to ensure continuous production is not interrupted. Power system due to accidental power failure, may lead to blast furnace slag spray, and burn the tuyere, or because of the gas pressure is not fast relief pressure, causing gas explosion and leakage and other endanger the safety of human life accidents; In addition, A power outage in the event of a power system failure also results in the control system becoming out of control and monitoring, hindering the prompt detection of points of failure and timely emergency response and rescue operations. It also adversely affects the subsequent analysis of the incident and the identification of the cause of the accident. Therefore, to improve the reliability of power supply and distribution system, is the blast furnace iron and steel engineering electrical equipment
