【摘要】：本文调研了电气安全的发展现状、国内外电气安全标准的情况以及臭氧发生器现有标准中有关电气安全的部分要求,结合实验室现有的臭氧发生器的使用情况,对其电气安全进行了分析,并针对电气事故,提出一定的对策。主要研究内容如下： (1)调研分析了臭氧发生器可能发生的电气事故,主要有雷击事故、静电事故、触电事故以及火灾事故。重点研究了触电事故和火灾事故的产生原因及防护措施。 (2)深入探讨了火灾事故产生的原因在于绝缘劣化和设备过热。对比分析了导线绝缘材料及绝缘板的常用材料,选择出耐臭氧性、阻燃性及绝缘性能较好的硅橡胶作为导线的绝缘材料和环氧树脂作为绝缘板。针对导线截面积选择不当导致的导线发热现象,进一步研究了在高频高次电流作用下的导线截面积选择问题,并对臭氧发生器内的导线截面积选择给出建议。 (3)深入研究了触电事故发生的主要原因为接地不良,且良好的接地也能预防静电事故。针对臭氧发生器的特殊性,2kW的臭氧发生器要求接地电阻小于2Ω,设计接地电极的组合方式,并完成施工。对比分析了几种接地电阻测量方式的优缺点,选择接地电阻测试仪测量接地电阻,分析了理论计算结果与测量结果存在误差的原因,并给出相应的建议。实验表明,本文臭氧发生器电气事故的解决方法是成功的,为设备和人身的安全提供了有力的保障。
[Abstract]:This paper investigates the current situation of electrical safety, the situation of domestic and international electrical safety standards, and the requirements of some of the existing standards of ozone generator, combining with the use of the existing ozone generator in the laboratory. The electrical safety is analyzed, and some countermeasures are put forward in view of the electrical accident. The main contents are as follows: (1) the possible electrical accidents of ozone generator are investigated and analyzed, including lightning accident, electrostatic accident, electric shock accident and fire accident. The causes and protective measures of electric shock accident and fire accident are studied emphatically. (2) the causes of fire accidents are insulation deterioration and overheating. By comparing and analyzing the common materials of conductor insulation material and insulating board, silicone rubber with good ozone resistance, flame retardancy and insulation property was selected as insulation material of conductor and epoxy resin as insulation board. In view of the phenomenon of conductor heating caused by improper selection of traverse cross-sectional area, the problem of traverse cross-sectional area selection under the action of high-frequency and high-order current is further studied, and suggestions are given for the selection of traverse cross-sectional area in ozone generator. (3) the main cause of electric shock accident is poor grounding, and good grounding can prevent electrostatic accident. In view of the particularity of ozone generator (2kW), the grounding resistance of ozone generator is less than 2 惟. The combination mode of grounding electrode is designed and the construction is completed. This paper compares and analyzes the advantages and disadvantages of several kinds of grounding resistance measurement methods, selects the grounding resistance tester to measure the grounding resistance, analyzes the reasons for the error between the theoretical calculation results and the measurement results, and gives some corresponding suggestions. The experimental results show that the method of solving the electrical accident of ozone generator is successful and provides a powerful guarantee for the safety of equipment and person.
