Abstract: 1. A reactive armor structure for protection against hollow explosive charge jets, said structure comprising an enclosure in which at least two reactive explosive elements are arranged, each of them is a three-layered element, the medium layer is an explosive charge lined with two metal plates, and the reactive explosive elements are positioned at an angle to the enclosure front wall, characterized in that the angle between the reactive explosive elements and the enclosure front wall is 5..90 degree , the explosive charge is divided in the reactive explosive element into at least two portions by a partition parallel to one of its face walls, the enclosure is provided with a protective shield installed with a gap respective to the container back wall. 2. A reactive armor structure according to claim 1, characterized in that neighboring reactive explosive elements are positioned in parallel planes, and the distance between the neighboring reactive explosive elements is 5...20 of the charge thickness of the explosive product. 3. A reactive armor structure according to claim 1, characterized in that the explosive charge of the reactive explosive elements is divided by a T-shaped partition into three rectangular compartments so that these two compartments abut the front or the back wall of the enclosure by their short sides, while the third side abuts by its longer side to the short sides of two other portions of the charge. 4. A reactive armor structure according to claim 1, characterized in that each portion of the divided charge together with the lining metal plates in the reactive explosive element is designed as a separate assembly, and the dividing partitions are formed be contacting face walls of these assemblies. 5. A reactive armor structure according to claim 1, characterized in that a filling layer with an apparent density 30...250 kg/m<3> is arranged in the enclosure cavity between neighboring reactive explosive elements. 6. A reactive armor structure according to claim 1, characterized in that the protective shield is made of high-strength armored steel and has a thickness 0,5...3,0 of the charge thickness of the reactive explosive element. 7. A reactive armor structure according to claim 1, characterized in that the reactive explosive members are elastic elements abutting the surface of the reactive explosive elements. 8. A reactive armor structure according to claim 1, characterized in that the reactive explosive members are elastic elements arranged inside the filling layer between the reactive explosive element. 9. A reactive armor structure according to claim 5, characterized in that the filling layer arranged between the reactive explosive elements is a foamed polymer material. 10. A reactive armor structure according to claim 6, characterized in that the protecting shield is common for 2..5 enclosures, and provided with fastening units to fasten enclosures to the protecting field, and fastening units to fasten the shield to an object to be protected. 11. A reactive armor structure according to claim 7, characterized in that the elastic element is made as a rubber plate and has a thickness 0,3...4,0 of the charge thickness of the reactive explosive element. 12. A reactive armor structure according to claim 7 or 8, characterized in that each elastic element is divided by a partition into two layers arranged inside of this elastic element and made of a material having density 2700...7850 kg/m<3>, wherein the partition has a thickness 0,1...0,5 of the charge thickness of the reactive explosive element. 13. An assembly arrangement for protection against hollow explosive charge jets, comprising a set of reactive armor structures according to any preceding claim.
