重大设备事故

变电站防误闭锁装置是防止运行电气设备误操作引发的人身和重大设备事故发生的重要措施。

The anti-taking degating device in substation is an important measure to prevent personal and serious facility accidents caused by incorrect operation in electric equipment running .

轧机是钢铁企业中的重要设备，其在运行中受到重载、冲击等负荷作用，出现了一些用静力学难以解释的重大设备事故。

The rolling mill is the critical equipment in Iron and Steel industry , and when it runs , heavy accidents often appear , which are difficult in explaining with statics when suffering from the load including deadweight , impulsive forces and so on .

针对10kV、35kV配电系统电容电流过大，引起弧光接地过电压，造成重大设备损坏事故的情况，阐述电容电流的几种测量方法及估算方法。

The capacitance current is excessive in 10 kV and 35 kV distribution systems , and it would cause arc grounding overvoltage , thereby it would destroy power equipment and enlarge accident area . Several measuring and estimation methods of capacitance current are described .

特别是对安全管理的目的是确保人身伤亡事故、重大变电设备事故和电网事故为零。

Safety management is designed to not occurring personal casualties , major substation equipment accidents , incidents grid .

综合考虑重大危险设备的事故严重度和事故发生频度，应用概率论方法对风险度进行定量评价，建立定量概率风险评价方法。

The seriousness and frequency of accidents of the key dangerous equipment were comprehensively considered , the probabilistic method was used to make quantitative assessment , and found the quantitative probabilistic risk assessment method .

随之，一些冶金企业的重大设备频频发生各种事故，这些事故中，最常见的也是最严重的是以裂纹为特征的起重机金属结构的疲劳破坏。

However , various accidents are appearing in every metallurgical enterprise , among which the most common and serious is fatigue destroy in crane metal structures which mostly are troubles of fatigue crack .
