【摘要】：随着社会经济的不断发展,人们对电能的需求越来越大,对电能的质量也提出了更高的要求,为我们提供电能的电力系统包括众多的电气设备,电气试验能及时发现电气设备故障隐患,监测设备运行状况,根据电气试验结果有计划对设备进行停电检修,避免电气设备故障临时停电,保证电力系统安全、经济运行。本文首先通过分析宁海供电公司电气试验工作现状,指出了电气试验安全工作的重要意义;其次分析了近几年电气试验人身伤亡事故,对事故发生的原因进行了分析,总结出电气试验过程中常见的违章和误操作,并针对这些安全隐患提出相应的对策。在发生事故隐患时通过切断试验电源终止高压试验的方法阻止事故的发生。在试验区域布置红外警戒防止人员误闯试验危险区域;利用低频无线传感技术识别试验工作人员的位置,防止试验工作人员人身触电;通过脚踏开关的设计限制试验监护人的位置,确保监护人履行好监护职责。高压试验安全防护系统研制成功后,通过功能测试,并在宁海县供电公司35kV长街变和宁海县雁苍山电力设备厂有限公司投入使用,安全防护系统的三重保护有效的保证试验现场人员和试验工作人员的人身安全。
[Abstract]:With the development of social economy, the demand for electric energy is increasing, and the quality of electric energy is also required. The electric power system that provides us with electric energy includes many electrical equipments. Electrical test can find hidden trouble of electrical equipment in time, monitor operation condition of equipment, carry out outage maintenance according to the result of electrical test, avoid temporary outage of electric equipment fault, ensure safe and economical operation of power system. By analyzing the current situation of electrical test work in Ninghai Power supply Company, this paper points out the important significance of electrical test safety work, and then analyzes the personal casualty accident of electrical test in recent years, and analyzes the causes of the accident. The common violations and misoperation in electrical test are summarized, and the corresponding countermeasures are put forward in view of these hidden dangers. The high voltage test is stopped by cutting off the test power when the hidden trouble occurs. The infrared warning is arranged in the test area to prevent the personnel from breaking into the dangerous area of the test by mistake, and the low frequency wireless sensor technology is used to identify the position of the test worker to prevent the test worker from being electrocuted. The position of the test guardian is limited by the design of the pedal switch to ensure that the guardian performs the duty of guardianship. After the development of the safety protection system for high voltage test, it passed the function test and put into use in the 35kV Changjie Substation of Ninghai Power supply Company and the YanCangshan Electric Power equipment Factory Co., Ltd of Ninghai County. The triple protection of the safety protection system effectively ensures the personal safety of the test site personnel and the test workers.
