[0006] To achieve the above-mentioned purpose, the insulating anti-electric arc clothing provided by the utility model comprises a clothing body, and the clothing body is sequentially provided with a protective layer and an insulating layer from inside to outside.

[0007] The surface of the insulating layer is formed with wrinkles by hot pressing, the height of the wrinkles is 4-6 mm, the spacing between adjacent wrinkles is 6-10 mm, and the wrinkles are irregularly distributed.

[0008] The protective layer comprises an inner lining and a plurality of protective pieces, the protective pieces are fixed to the inner lining, and the protective pieces have a grid structure.

[0013] In some embodiments of the utility model, the buffer layer is further provided with a plurality of flat air passages, and the cavities are communicated through the air passages.

[0014] In some embodiments of the utility model, the insulation gas is nitrogen.

[0015] In some embodiments of the utility model, the insulation layer is formed by interweaving mica sheets and insulation fibers.

[0016] In some embodiments of the utility model, the folds are more dense at the joint parts of the clothing body and are adapted to the movement direction of the joints.

[0032] Referring to the accompanying Figures 1-6 The utility model provides a kind of insulating arc-proof clothes, insulating arc-proof clothes includes dress body 1000, dress body 1000 is sequentially provided with protective layer 200 and insulating layer 100 from inside to outside;

[0033] The surface of the insulating layer 100 is formed with wrinkles 110 by hot pressing, the height of the wrinkles 110 is 4-6mm, the distance between adjacent wrinkles 110 is 6-10mm, and the wrinkles 110 are irregularly distributed.

[0034] The protective layer 200 includes an inner lining 210 and a plurality of protective pieces 220, the protective pieces 220 are fixed to the inner lining 210, and the protective pieces 220 have a grid structure 221.

[0035] The inner lining 210 is detachably mounted on the insulating layer 100.

[0036] Based on the above technical features, the wrinkles 110 formed on the surface of the insulation layer 100 by hot pressing have a height of 4-6 mm, an irregular distribution, and a spacing of 6-10 mm between adjacent wrinkles 110. By setting the height and spacing, the distance of arc creeping on the surface of the insulation layer 100 is increased, making it difficult for the current to form a continuous conductive path on the surface of the insulation layer 100, thereby further improving the electrical insulation performance of the insulating clothing and effectively reducing the risk of electric shock. The irregularly distributed wrinkles 110 can disperse external stress and prevent stress concentration from damaging the insulation layer 100. In actual use, when the insulating clothing is subjected to external forces such as compression and friction, the wrinkles 110 can act as a buffer to protect the integrity of the insulation layer 100 and maintain its good insulation performance. The protective member 220 in the protective layer 200 has a grid structure 221, which has a certain elasticity and toughness. When an arc explosion produces a shock wave, the protective member 220 of the grid structure 221 can absorb and disperse the energy of the shock wave, reducing its impact on the human body and reducing the likelihood of mechanical damage to the human body. The grid structure 221 of the protective member 220 can effectively block arcs and splashed molten metal particles. When an arc contacts the grid structure 221, its energy is dispersed and attenuated; when molten metal particles hit the grid, they are intercepted and cannot directly contact the human body, thereby providing reliable protection against electric arcs for workers. The combination of the insulation layer 100 and the protective layer 200 achieves current insulation while meeting the protection requirements for arcs.

[0037] The inner liner 210 is detachably mounted on the insulation layer 100, which allows the protective layer 200 to be replaced or cleaned as needed. When the protective layer 200 is severely damaged or contaminated during use, the inner liner 210 can be easily detached from the insulation layer 100 for repair or replacement of a new protective layer 200, extending the service life of the insulating anti-arc clothing and reducing the cost of use. The inner liner 210 can be detachably connected to the insulation layer 100 through conventional detachable structures such as Velcro or zippers.

[0038] Further, the wrinkles 110 are provided with a plurality of through-hole structures that penetrate the insulation layer 100, and the aperture of the through-hole structure is 1-2 mm. When an arc occurs, it will produce high temperature and high pressure in a short time. If this high pressure is not released in time, it may cause the internal pressure of the clothing to rise sharply, thereby increasing the risk of arc penetration through the clothing. The presence of the through-hole provides a release channel for high-pressure gas, allowing the pressure to be quickly reduced and reducing the likelihood of insulation failure due to excessive pressure, thereby maintaining the insulation performance to some extent.

[0039] Meanwhile, the through holes are arranged to make the current need to bypass the holes when conducting on the surface of the material, thereby increasing the creepage distance. The longer creepage distance means that it is more difficult for the current to form a continuous conductive path on the surface of the insulating material, thereby improving the electrical insulation performance of the material and reducing the possibility of arc propagation along the surface of the material.

[0040] The through holes, the corrugations 110 and the protective layer 200 can work together. When the arc impacts the garment, the corrugations 110 first buffer part of the energy, the through holes release pressure and heat, and the protective member 220 of the protective layer 200 further disperses the arc energy, and the three work together to enhance the insulation and protection effect of the entire protection system.

[0041] The grid structure 221 of the protective member 220 includes metal wires and plastic wires that are cross-woven to form, and every several plastic wires are inserted with a metal wire. The metal wires have good electrical conductivity, and when the arc contacts the grid structure 221 of the protective member 220, the metal wires can quickly disperse the current generated by the arc. Since every several plastic wires are inserted with a metal wire, the metal wires are connected to each other to form a conductive path, which can guide the energy of the arc to a larger area, thereby reducing the damage of the arc to the protective layer 200 and the human body. The cross-woven metal wires and plastic wires can intercept the arc and the splashed molten metal particles. The strength of the metal wires can resist a certain impact force, and the plastic wires can play a buffering and supporting role, and the combination of the two makes the grid structure 221 perform well in blocking the arc and buffering the impact.

[0042] Specifically, the plastic wires have good insulation performance, and the interval arrangement of the plastic wires can effectively isolate the adjacent metal wires to prevent the current from conducting randomly between the metal wires, and ensure that the protective member 220 as a whole still maintains good insulation performance under normal circumstances.

[0043] It should be noted that the grid structure 221 can be arranged at important parts of the human body, such as the chest, back or abdomen, to improve the protection effect of the important parts of the human body.

[0044] In this embodiment, the garment body 1000 is further provided with a buffer layer 300, and the garment body 1000 is sequentially provided with the buffer layer 300, the protective layer 200 and the insulation layer 100 from inside to outside; the buffer layer 300 is provided with a plurality of flat cavities 310, and the cavities 310 are filled with insulating gas; the design of the flat cavities 310 increases the flexibility and elasticity of the buffer layer 300, so that the garment can better fit the human body curve and reduce the restriction on human activities; the insulating gas filled in the cavities 310 can further enhance the impact resistance. When the shock wave is generated by the explosion of the arc, the insulating gas in the cavities 310 can be compressed to absorb and disperse the energy of the shock wave.

[0045] The insulation gas itself has good insulation characteristics, and filling in the cavities 310 further improves the insulation performance of the buffer layer 300. This makes the buffer layer 300 play a dual role in preventing electric arc and insulation, cooperating with the external protective layer 200 and the insulation layer 100, to form a more reliable insulation protection system. Even if the electric arc breaks through the protection of the outer layer, the insulation gas in the buffer layer 300 can prevent the conduction of current to the human body to a certain extent, providing additional safety protection for the operating personnel.

[0046] Further, the buffer layer 300 is also provided with a plurality of flat air passages 320, and the plurality of cavities 310 are connected in communication through the plurality of air passages 320; the flat air passages 320 provided on the buffer layer 300 connect the plurality of cavities 310 in communication, and when the cavities 310 are impacted by the shock wave generated by the explosion of the electric arc, the pressure balance between the cavities 310 can be realized. When a cavity 310 is subjected to a larger pressure, the gas can flow rapidly to other cavities 310 through the air passages 320, avoiding damage to the buffer layer 300 caused by excessive local pressure; the gas flow also helps to maintain the uniformity of the distribution of the insulation gas, avoiding the decline of the insulation performance caused by the accumulation or stratification of the gas.

[0047] Specifically, the insulation gas is nitrogen, which realizes buffering while meeting the insulation effect.

[0048] The insulation layer 100 is formed by interweaving mica sheets and insulation fibers to realize the insulation protection effect; the protective layer 200 is made of fiber or composite material, and the buffer layer 300 can be made of fabric composite material or polyester fiber material, which is not specifically limited here.

[0049] Further, at the joint parts of the clothing body 1000, the wrinkles 110 are more dense and the direction is adapted to the movement direction of the joint; the dense wrinkles 110 not only increase the surface area to disperse stress, but also form a complex path on the surface to increase the creepage distance and improve the electrical insulation performance of the joint parts.

[0050] In the embodiment, the clothing body 1000 includes a garment 1100 and trousers 1200, realizing protection of the human torso and lower limbs.

[0051] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
