Basic requirements and protective measures for live line work

safety protective measures are important to ensure the safety of production workers in live line work. However, everyone has never thought that the expensive experimental box may not be one of the measures suitable for us. Live line work has special requirements, and live line work tools bear the effect of both electrical and mechanical loads in the working state. Therefore, the selection of safety protective equipment is very important

carefully select protective appliances

the new capacity of domestic power batteries in 2016 is 2.8 times that in 2015

safety protective appliances for live line operation should not only have high electrical insulation strength, but also have good moisture-proof performance and wearability, which can ensure safety and facilitate the operation of power workers. The quality of tools is directly related to the safety of operators and equipment. Therefore, tools and instruments for live working should be safe and reliable, with reasonable structure, sufficient strength, advanced technology, light and flexible. Tools with good water splashing performance should also be selected for working in rainy days and water washing tools and instruments. The most basic protective equipment in live working includes:

insulating gloves and protective gloves. Insulating gloves are the most important personal protective equipment for operators in live working. As long as they contact live bodies, whether they are live or not, operators must wear gloves before working. Insulating gloves should have both high-performance electrical insulation strength and mechanical strength, good elasticity and durability, and soft service performance, so as to minimize the discomfort and fatigue of hands. Soft leather gloves are only used as mechanical protection of insulating gloves to prevent the insulating gloves from being cut, torn or punctured. They cannot be used alone as protection against electric shock. Leather protective gloves should be made of special leather. While providing sufficient mechanical strength protection, they should also have good service performance. The size should be consistent with the insulating gloves. The top of the opening and the top of the opening of the rubber insulating gloves should maintain a minimum clearance distance

insulating clothing and insulating pants. Insulating clothes and insulating pants are made of EVA resin material, with good insulation performance, moderate mechanical strength, soft and light, and comfortable to wear. The insulating clothing needs to be strictly tested before leaving the factory to provide comprehensive insulation protection. Among them, the insulated pants are of strap design

insulating boots. Insulating boots are auxiliary insulation safety appliances used in live line operation. In addition to good electrical insulation, they must also have a certain physical and mechanical strength to prevent puncture or wear. Long insulating boots can be used with insulating pants to provide comprehensive personal insulation, and the front of group A is pasted to the rubber film for safety protection

insulating cap. Ordinary safety helmets cannot be used in live working because their insulation characteristics are not stable enough. During live working, insulating helmets shall be used, and high-density composite polyester materials shall be used. While meeting the mechanical strength of helmet testing standards, it shall also meet the relevant electrical testing standards for live working of power distribution, and its dielectric strength shall pass the 20kV testing test

protective glasses. Live line work is usually carried out in the air, so eye protection is very important. The correct use of safety glasses can avoid the stimulation of sunlight, effectively prevent the risk of eye injury caused by splashing of dust, iron filings and other objects, prevent the stimulation of smoke and chemicals on the eyes, and prevent the impact on the line of sight caused by the condensation of water vapor

do a good job in the maintenance of protective equipment

carefully select protective equipment during operation to ensure the safe and smooth operation of live line operation. After the operation is completed, the maintenance of safety protection equipment should also not be ignored. Since such appliances are easily damaged plastic or rubber products, and there are various metal equipment on the operation site, protective appliances are very easy to be scratched or damaged during operation. Therefore, relevant personnel carrying out live line operation should carefully check the appliances before and after the operation, find problems in time, and prevent accidents caused by insulation protection damage

because these appliances are airtight, they will make the human body feel uncomfortable and cause a lot of sweat when used, especially in summer, these appliances will be soaked by human sweat, so operators should remove the water stains immediately after use to avoid the chemical reaction between salt and alkali contained in sweat and plastic and rubber clothing, which will reduce the service life of protective appliances
