Abstract: 1. A device of reactive armor for protection of hollow charges, comprising container, where at least two explosive reactive elements are located, each being three-layered, with the middle layer of explosive agent, coated with two metallic plates, and explosive reactive elements are installed at the angle to front wall of the container, characterized in that the angle between the explosive reactive elements and front wall of the container is 5...90 degree , explosive agent charge in explosive reactive elements is divided on at least two parts by partition, parallel to one of face sides, container being provided by protective screen, installed with a gap to back wall. 2. A device of reactive armor according to claim 1, characterized in that the adjacent explosive reactive elements are installed in parallel plains, and the distance between the adjacent explosive reactive elements is 5...20 of the thickness of their charge of explosive agent. 3. A device of reactive armor according to claim 1, characterized in that the explosive agent charge in explosive reactive elements is divided by T-shaped partition on three parts of squared shape so that these two parts are turned on the front or back walls of the container by short sides, and the third part of that charge is joining with long side to short sides of two other parts of the charges. 4. A device of reactive armor according to claim 1, characterized in that in explosive reactive element each part of divided explosive agent charge with corresponding metallic plates is made as a separate construction, and the partitions dividing the explosive agent charge are formed by intercontacting face walls of said separate constructions. 5. A device of reactive armor according to claim 1, characterized in that a stuff layer with the apparent density of 30...250 kg/m<3> is located in cavity of container between the adjacent explosive reactive elements. 6. A device of reactive armor according to claim 1, characterized in that the explosive reactive elements are completed with elastic elements, adjacent to the surface of explosive reactive elements. 7. A device of reactive armor according to claim 1, characterized in that that the explosive reactive elements are completed with elastic elements, installed inside of stuff layer, located between explosive reactive elements. 8. A device of reactive armor according to claim 1, characterized in that that the container is provided with additional screen, installed with a gap to face wall of the container. 9. A device of reactive armor according to claim 1 or 8, characterized in that the protective screen or additional screen or both of them are made of armor steel and have the thickness of 0.25...3.0 of the thickness of explosive agent charge of the explosive reactive element. 10. A device of reactive armor according to claim 5, characterized in that the stuff layer, placed between he explosive reactive elements is made of foamed polymeric material. 11. A device of reactive armor according to claim 6 or 7, characterized in that the elastic element is made as a plate from rubber or textolite, with the thickness of 0.3...4.0 of the thickness of explosive agent charge of explosive reactive element. 12. A device of reactive armor according to claim 6 or 7, characterized in that each elastic element is divided on two layers by partition, located inside of said elastic element and made of material with density 2700...7850 kg/m<3>, partition having thickness of 0.1... 0.5 of the thickness of the explosive agent charge of the explosive reactive element. 13. A device of reactive armor according to claim 8, characterized in that in the gaps between additional screen and face wall of the container, between back wall of container and protective screen and protected object, or the stuff layer with apparent density of 30...1950 kg/m<3> is located in any of this gaps. 14. A device of reactive armor according to claim 9, characterized in that the protective screen is common for 2...6 containers, and is provided with attachment point of the containers to the protective screen, and also the attachment points to protected object. 15. Built-up construction for protection of hollow charges, comprising a set of devices of reactive armor according to any preceding claims.
