| 1、绝缘靴、鞋跟普通的靴、鞋有什么不同? 1. What's the difference between insulating boots and shoes with regular heels? 绝缘靴、鞋跟普通的靴、鞋在设计上不同,绝缘靴、鞋在结构设计上采用绝缘橡胶材料制作的围条,绝缘层形成密闭的绝缘体系来保护足部。 普通的靴、鞋则不同,普通的靴、鞋的大底与海绵不是用的绝缘材料,绝缘性能很低容易漏电。有的泄漏电流高达30mA远远超出安全电流,绝缘靴鞋逐只进行电性能检验,合格后方可出厂。普通靴鞋没有此项要求。 Insulating boots, heel ordinary boots and shoes in the design, safety boots, shoes made of rubber insulation material in the structural design of round bar, airtight insulation system insulating layer formed to protect the foot. Ordinary boots, shoes are different, ordinary boots, shoe and sponge are not used insulation materials, insulation performance is very low and easy to leak electricity. Some leakage current as high as 30mA is far beyond the safety current, the insulation shoe shoe is tested by the electric property only, qualified rear can leave the factory. Regular boot shoes are not required. 2、绝缘防护用具为什么要保持干燥状态下穿戴? 2. Why should the insulating equipment be kept dry? 绝缘防护用具在干燥状态下穿戴是使用者必须注意的大问题,因为绝缘防护用具如果含有一定量的水分,使其绝缘体的体积电阻与表面电阻值大大降低。水是导体,由于水的存在,使绝缘体的绝缘性能大大降低甚至破坏。因为水的原子构成角∠HOH=105°具有强的极性能生成离子导电,再一个水中有许多杂质在热、光、电的作用下能发生化学变化而生成导电体,而破坏绝缘性能,所以保持绝缘防护用具的干燥,能极大地提高安全性能。 Wear insulating protection appliance in a dry condition is a huge problem, users must pay attention to, because insulation protection appliance if contain a certain amount of moisture, make its insulators volume resistance and surface resistance value is reduced greatly. Water is a conductor, and because of the presence of water, the insulation of the insulator is greatly reduced and even destroyed. Because the atoms of water < HOH = 105 ° Angle has a strong polar generated ion conductive performance and then a water has many impurities under the action of heat, light, electricity, chemical changes can happen and generate the conductive body, and destroy the insulation performance, so keep dry insulation protection appliance, can greatly improve the safety performance. 3、绝缘防护用具的绝缘性能好坏的最主要指标是什么? 3. What are the main indicators of the insulation performance of insulating protective appliances? 绝缘防护用具(绝缘靴、鞋、手套等)穿戴的目的是防止触电伤害主要是人体通过电流造成,因此绝缘体的防护性能的好坏主要看在一定的电压下所通过的泄漏电流的大小,如果泄漏电流是在安全电流数值范围之内是安全的,否则是不安全的。如果施加一定的电压,尽管没有造成击穿,但泄漏电流过大同样造成人体伤害。 Insulated protective appliances (insulating boots, shoes, gloves, etc.) to wear the purpose is to prevent electric shock damage mainly due to the human body through the current, therefore an insulator protective performance is good or bad depends mostly under a certain voltage by the size of the leakage current, if the leakage current is in the range of safe current numerical is safe, it is not safe. If a certain voltage is applied, although no breakdown is caused, the leakage current is too large to cause human injury. 4、绝缘防护用品为什么要进行预防性试验? 4. Why should I have a preventive test? 进行预防性试验,是电力行业的严格规定保证人身的安全万无一失。绝缘防护用品有的三包期比较长,在这么长的时间内,由于其老化作用或贮存等条件造成的变化,从安全第一的角度用户在使用前进行预防性试验是必须的。属于绝缘靴鞋如果超出三包还可以进行预防性试验,合格后,方可使用。 To carry out preventive test, it is the strict regulation of electric power industry to ensure the safety of the person. Insulation protection articles 3 bag period is longer, in such a long time, because of its ageing effect or storage conditions caused by the change, from the Angle of safety first, the user before use preventive test is a must. If you have more than three bags, you can use them. |
