Description of drawings
The present invention is further described in conjunction with the accompanying drawings and embodiments for existing face.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structure cutaway view.
Among the figure: 1, conjoined clothes, 2, junction button, 3,4, the thermal stabilization shield gloves, 5,6, the conduction socks, 7, conductive fabric, 8, every combustion cloth, 9, the fine heat insulation felt of carbon, 10, the real silk lining.
The specific embodiment
As shown in Figure 1, high-voltage hot-line work comprises upper garment, trousers, cap (containing face shield), gloves, socks with thermal stabilization shield one clothes.Their annexation is: cap (containing face shield), upper garment and trousers are unified into thermal stabilization shield conjoined clothes 1, two thermal stabilization shield gloves 3,4 utilize the junction button 2 of conductive material making and the cuff of conjoined clothes 1 upper garment to link to each other respectively, and two conduction socks 5,6 utilize the junction button 2 of conductive material making and the leg opening of whole trousers of obeying to link to each other respectively.
As shown in Figure 2, what conjoined clothes 1,3,4 and two conductions of two thermal stabilization shield gloves socks 5,6 all adopted is four-layer structure, and outermost layer is a conductive fabric 7, the solution shielding properties, and electric conductivity, every electric index such as discharge capacity is to satisfy the requirement of livewire work.The second layer is every combustion cloth 8, solves the powerful problem of heat insulation felt, also plays certain heat-blocking action simultaneously, adopts carbon fiber sheet.The 3rd layer is the fine heat insulation felt 9 of carbon, solves heat-insulating problem, the heat-insulation blanket that thermal insulation layer is made for the carbon fibrillated short fiber.The innermost layer is a real silk lining layer 10, solves the wearing comfortableness problem.It is identical with the heat insulation one clothes of normal shielding that the style of clothes is connected with the distribution of shunt line.Described fire retardant adopts carbon fiber sheet.
Outermost conductive fabric 7 requires the dress material shield effectiveness must not be less than 40dB, dress material resistance must not be greater than 0.8 Ω, blowout current is greater than 5A, modification not when 200 ℃ of high temperature, do not change shielding properties. be the blended cloth of making by stainless steel fibre, fire resistance fibre, tussah silk and monel wire, the weight portion of four kinds of fibers is: 30 parts of stainless steel fibres, 37 parts of fire resistance fibres, 30 parts of tussah silks, 3 parts of monel wire. the softening point of fire resistance fibre that is to say that at 190 ℃ fiber begins softening the contraction in the time of 190 ℃; And begin to decompose during 235 ℃ of tussah silks, there is not softening contraction process. this raw-material combination, make the heat-shrinkable of yarn obtain changing. when weaving lining, added a certain amount of monel wire simultaneously, the conductive fabric that has so just guaranteed lining does not shrink modification in the time of 200 ℃, various performance indications do not change.
The second layer is stitched together every combustion cloth 8 and the 3rd layer of carbon fibre heat insulation felt 9 and forms the heat-insulating flame-retardant layer.The heat-insulating flame-retardant layer requires to glow 0 second time, after flame time 0 second, char length 0mm, no fusion, drippage; In the time of 200 ℃ 80 seconds, clothes internal layer temperature≤60 ℃.
The heat-insulating flame-retardant layer is determined: clothes heat insulation needs certain thickness and completely cuts off heat, need in light weight, not heat conduction, good flame resistance, the fiber that tensile strength is high is made heat insulation felt, the fiber that meets this condition has Nomex fiber, Kevlar fiber, pbo fiber, PBI fiber and carbon fibre, the proportion of comprehensive above-mentioned fiber, intensity, performance such as fire-retardant, finally selected carbon fibre, it is the proportion minimum in these fibers, intensity is the highest, and fire resistance is best, can be in the time of 100 ℃ not modification do not burn.Though carbon fibre single fiber brute force is the highest, but after making heat-insulation blanket by its short fiber, the tension brute force of heat-insulation blanket is very low, do not reach and take requirement, for the powerful problem of the tension that solves heat insulation felt, adopt fire retardant and heat insulation felt quilting together, make two-layer compound becoming one, effectively solved the tension problem.
Lining is selected silk broadcloth for use, has improved wearing comfortableness.
Above-mentioned apparel construction and material, outermost layer shielding, second layer anti-flaming thermal-insulation, not only certain heat can be completely cut off but also the tensile strength of heat insulation felt can be increased, when the fine heat insulation felt of the 3rd layer of carbon, this structure can guarantee 200 ℃ of high temp objects of human body contact, the skin sense temperature was less than 60 ℃ in 80 seconds.The innermost layer silk broadcloth is expected as the lining, can improve the comfortableness of clothes.
