Application of high-voltage insulated boots, classification of pressure rating and precautions
Application of high voltage insulated boots
High-voltage insulated boots are mainly used as auxiliary safety tools for electrician work in high-voltage power equipment, and can be used as basic safety equipment below 1kV. The product adopts anti-corrosion metal plate as the middle pad, steel anti-rust inner wrapper, and the boot type conforms to the principle of human body mechanics. It has advanced technology, flex resistance, aging resistance, strong water resistance, advanced technology, comfortable wearing and convenient movement. Features, can effectively prevent a variety of things from stabbing the soles of the feet, protecting the toe safety. Applicable to power mines, fire protection, factories, construction, forestry and other departments.
High-voltage insulated boots withstand pressure classification
The new standard stipulates that electrically insulated shoes are used as safety aids for electrical work. As a labor safety manager, this should be clearly understood. Often, some managers with insufficient electrical knowledge mistakenly believe that 6KV insulation shoes or 5KV cloth insulation shoes, the application range is 6KV or 5KV environment, which is very wrong. In electrical safety management, insulation tools are divided into basic safety tools and auxiliary safety equipment. The so-called basic safety equipment refers to safety equipment with sufficient insulation strength to withstand the electrical application voltage, such as insulating rods, insulating clamps, and insulation tables (ladders). The auxiliary safety tools are not enough to withstand the electrical operating voltage. In electrical work, the basic safety equipment (such as insulating mats, insulated shoes) can not touch the live parts. But it can prevent the impact of step voltage on the human body. Insulating shoes and cloth insulation shoes are mainly used as auxiliary safety tools under the power frequency of 1000V.
Voltage levels can generally be divided into: 6kv insulated boots, 20kv insulated boots, 25kv insulated boots and 35kv insulated boots. Use in environments that adapt to different voltage levels.
According to the requirements of the new standard, the thickness of the outer sole of the electric insulation shoe shall not be less than 4 mm, and the thickness shall not be less than 6 mm when the pattern cannot be measured. In the current market, the phenomenon of replacing the labor-insulated shoes with the life soles often occurs. It is the thickest part of the sole and it is less than 6 mm. The upper or sole of the insulated shoes purchased by the company shall have standard number, insulation type and voltage value. Companies should also understand the qualifications of manufacturers.
The length of the outer sole wear scar of the electric insulation shoes should be no more than 10mm; the wear reduction of the electric insulation cloth shoes is not more than 1.4cm3; the wear reduction of the 15kv and the electric insulation rubber boots is not more than 1.0cm3; the wear of the electric insulating rubber boots of 20kv and above The reduction is not more than 1.9cm.
The new standard GB12011-2000 for electric insulating boots has made specific provisions from production, packaging, transportation, storage and use. It not only constrains the manufacturer to continuously improve the quality, but also puts forward new requirements for the product users: when using, avoid sharp stab wound soles, keep the uppers dry during use, and avoid high temperature and corrosive substances. In particular, the labor safety supervision department should conduct the handover test for the purchase of new insulation shoes. After the product has been worn for 6 months, a preventive test should be carried out. For the defective product pierced by the sharp device, it should not be used as an insulated shoe.
Preventive test, for 6KV leather insulated shoes, 5KV voltage detection should be used. 5KV cloth shoes use 3.5KV testing. Implementing the new GB12011-2000 standard is the common responsibility of product manufacturers and users. Only by implementing the standards and grasping the requirements of the standards can the safety accidents caused by electric shocks be reduced. The new standard of GB12011-2000 electric insulation shoes is beneficial to manufacturers to improve product quality, is conducive to enterprise safety and production management, and improves the safety management level and safe operation level of enterprises to prevent electric shock accidents.
High voltage insulation boots precautions
1. Insulated shoes should be correctly selected according to the high and low voltage of the workplace. Low-voltage insulated shoes are forbidden to be used as safety aids on high-voltage electrical equipment. High-voltage insulated shoes (boots) can be used as auxiliary safety tools on high-voltage and low-voltage electrical equipment. However, no matter whether it is wearing low-voltage or high-voltage insulated shoes (boots), you should not touch the electrical equipment directly with your hands.
2, cloth insulation shoes can only be used in a dry environment to avoid wet cloth.
3. The use of insulated shoes (boots) must not be damaged.
4. When wearing insulated boots, the pants should be placed in the boot. When wearing insulated shoes, the trousers should not be long and the height of the outer edge of the sole should not be longer and the ground should be kept dry.
5, non-acid and alkali resistant rubber sole, can not be in contact with acid and alkali oil substances, and should prevent sharp objects from stabbing. Low-voltage insulated shoes cannot be used as insulated shoes if the bottom pattern is polished to reveal the internal color.
6. When purchasing insulated shoes (boots), check whether there are permanent insulation marks on the shoes, such as red lightning symbol, the sole has excellent voltage resistance, etc.; whether there is a certificate of conformity in the shoes, safety appraisal certificate, production license Number, etc.
The application of high-voltage insulated boots, the classification of pressure-resistant grades and precautions are introduced so much. Good insulation is a necessary condition for ensuring the normal operation of equipment and lines, and is also an important measure to prevent electric shock accidents. Therefore, it is very important to choose high-quality insulated boots with qualified quality. I hope that when you choose, you must not choose cheap or save things and choose some unqualified products. This will not only prevent danger but also cause serious consequences.
