急需翻译一篇英语文章

本人是学电力系统的，只能帮你提供电气工程方面的文章。 电气安全概述一、Electrical safety task :1) to study various electrical accident and the mechanism of reasons, the patterns and characteristics and protective measures. (2) to study the use of electrical methods, electrical monitoring, Electrical inspection and electrical control methods to evaluate the safety of the electricity system and electricity production solve the security problems. 二、Electrical Safety Work content ： 1) Study and to take effective security measures. (2) research and the dissemination of advanced electrical safety technology to improve electrical safety standards.(3) Develop and implement technical standards for security and safety technology point of order. (4) Establish and implement a safety management system. (5) in the thinking of electrical safety and electrical safety education. (6) analyze the case, find out the cause of the accident and the law. 三、Guarantee the security of electricity fundamentals :(1) Electrical Insulation. Maintain distribution lines and electrical equipment in good insulation, is to guarantee personal safety of electrical equipment and the normal operation of the most basic elements. Electrical Insulation whether the performance of good, by measuring the insulation resistance, crushing strength, Leakage Current and dielectric loss, and other parameters measured. (2) a safe distance. Electrical safety distance is the body charged objects close to the body, such as dangerous without the safety and reliability of distance. If body charged with the ground between the body charged with charged between, and the human body charged between body charged with other facilities and equipment between shall maintain a certain distance. Usually, the distribution lines and changes and distribution installations near work, it should consider a safe distance from the line that changed, Distribution Equipment safe distance, a safe distance from the maintenance and safe operation of distance. 3) safety carrying capacity. Conductor set the security flow is allowed to persist through the internal conductor CURRENT. Conductor sustained through the current security set excess flow, heat conductors will exceed the allowable values, damage to the insulation, even lead to leakage and fire. Therefore, in accordance with the security conductor containing a conductor cross section to determine flow and the selection of equipment is very important. (4) signs. Clearly, accurate, uniform signs is to ensure that electricity security of the important factors. Generally, a color logo signs, badges and signs model markings, and so on. A different color marker nature of the different uses wire; General badges as a sign of dangerous places signs; Model equipment as a sign of special signs. 四、Security technology of electrical equipment basic requirements。 electrical accident statistics show that the electrical equipment as structural defects, installation of poor quality and can not meet the safety requirements caused by the large proportion of accidents. Therefore, in order to ensure personal safety and equipment safety, technical aspects of electrical equipment have the following requirements :1) exposed on the ground and the personal touch easier Charged equipment, should take protective measures reliable. (2) charged equipment and the ground and some other parts should be charged to maintain a safe distance.(3) easy to over-voltage power system, there should be a lightning lightning line arrester, Protection gap voltage protection, and other devices. (4) low voltage power system should be grounded, zero protection device. (5) to all high voltage electrical equipment to be taken to install high voltage circuit breakers and fuses different types of protection measures; Low-voltage electrical equipment to be used with correspondingly low electrical protection measures for the protection. (6) in electrical equipment, the siting of safety signs should be located. (7) According to some electrical equipment characteristics and requirements, should take special security measures. 5, electrical accidents basic reasons for the classification and the classification by electrical accident occurred in the form of disaster can be divided into personal accident, equipment accident, the electrical fire and explosion accidents By accident when the circuit conditions can be divided into short-circuit accidents, break accident, grounding accidents, leakage accident; according to the seriousness of the incident can be divided into serious accidents, serious accidents, incidents general; by the extent of injury. can be divided into death, serious injury, three minor injuries. 由于本人学士不够,只能帮你这点小忙了。一、电气安全工作的任务： （1） 研究各种电气事故及其发生的机理、原因、规律、特点和防护措施。 （2） 研究运用电气方法，即电气监测、电气检查和电气控制等方法来评价电力系统的安全性和解决生产中用电的安全问题。 二、 电气安全工作的内容 （1） 研究并采取各种有效的安全技术措施。 （2） 研究并推广先进的电气安全技术，提高电气安全水平。 （3） 制定并贯彻安全技术标准和安全技术规程。 （4） 建立并执行各种安全管理制度。 （5） 开展有关电气安全思想和电气安全知识的教育工作。 （6） 分析事故实例，从中找出事故原因和规律。 三、 保证用电安全的基础要素 （1） 电气绝缘。保持配电线路和电气设备的绝缘良好，是保证人身安全和电气设备正常运行的最基本要素。电气绝缘的性能是否良好，可通过测量其绝缘电阻、耐压强度、泄漏电流和介质损耗等参数来衡量。 （2） 安全距离。电气安全距离，是指人体、物体等接近带电体而不发生危险的安全可靠距离。如带电体与地面之间、带电体与带电体之间、带电体与人体之间、带电体与其他设施和设备之间，均应保持一定距离。通常，在配电线路和变、配电装置附近工作时，应考虑线路安全距离，变、配电装置安全距离，检修安全距离和操作安全距离等。 （3） 安全载流量。导体的安全载流量，是指允许持续通过导体内部的电流量。持续通过导体的电流如果超过安全载流量，导体的发热将超过允许值，导致绝缘损坏，甚至引起漏电和发生火灾。因此，根据导体的安全载流量确定导体截面和选择设备是十分重要的。 （4） 标志。明显、准确、统一的标志是保证用电安全的重要因素。标志一般有颜色标志、标示牌标志和型号标志等。颜色标示表示不同性质、不同用途的导线；标示牌标志一般作为危险场所的标志；型号标志作为设备特殊结构的标志。 四、 安全技术方面对电气设备基本要求 电气事故统计资料表明，由于电气设备的结构有缺陷，安装质量不佳，不能满足安全要求而造成的事故所占比例很大。因此，为了确保人身和设备安全，在安全技术方面对电气设备有以下要求： （1） 对裸露于地面和人身容易触及的带电设备，应采取可靠的防护措施。 （2） 设备的带电部分与地面及其他带电部分应保持一定的安全距离。 （3） 易产生过电压的电力系统，应有避雷针、避雷线、避雷器、保护间隙等过程电压保护装置。 （4） 低压电力系统应有接地、接零保护装置。 （5） 对各种高压用电设备应采取装设高压熔断器和断路器等不同类型的保护措施；对低压用电设备应采用相应的低电器保护措施进行保护。 （6） 在电气设备的安装地点应设安全标志。 （7） 根据某些电气设备的特性和要求，应采取特殊的安全措施。 五、 电气事故的分类及基本原因的分类 电气事故按发生灾害的形式，可以分为人身事故、设备事故、电气火灾和爆炸事故等；按发生事故时的电路状况，可以分为短路事故、断线事故、接地事故、漏电事故等；按事故的严重性，可以分为特大性事故、重大事故、一般事故等；按伤害的程度，可以分为死亡、重伤、轻伤三种。
