FIELD: safety.SUBSTANCE: protective shielding set from electric shock when working in area of induced voltage and from effects of electric fields of industrial frequency comprises costume in form of a jacket with a hood, trousers or overalls and a helmet, as well as gloves and boots. Hooded jacket, pants or overalls, helmet and lining of shoes made of a single layer of non-combustible heat-shielding double-sided fabric made weaving conductive metallised yarn and non-conductive heat-resistant yarns, wherein outer side of single-layer non-combustible heat-shielding double-sided fabric is current-conducting and shielding, and inside is dielectric, providingEFFECT: electrical insulation of user's body from current-conducting elements of set; screening set has a limit value of electric current flowing through body dressed in the human kit, no more than 6 mA, electrical resistance of a set of assemblies of less than 10 ohms, electrical resistance of hand protection of less than 30 ohms, electrical resistance of shoe at least 4,000 ohm and bypass ratio - ratio of electrical current flowing through set to force of an electric current flowing through user's body, a set of 5,300 while flowing through set current value 1 A, 9,300 when flowing through a set current value of 90 A, and shielding factor - ratio of voltage applied to set to voltage on body of user in space under clothes over 20,000 while in an electric field of 200 kV voltage source.7 cl, 1 dwg |
