Изобретение относитс к строительству и предназначено дл молниезащиты объектов, занимаюи1их большую площадь включающих сооружени , имеющие большую высоту, расположенные в средней части объекта, и требующие над собой свободного пространства.The invention relates to construction and is intended for lightning protection of objects that occupy a large area including structures, having a large height, located in the middle part of the object, and requiring free space above themselves.

Известно молниезащитное устройство , включающее расположенный над защищаемым объектом молниеприемник в виде поддерживаемых опорами имеющими одинаковую высоту параллельных тросов. Тросы образуют общую зону защиты l.A lightning protection device is known, which includes an interception rod located above the protected object in the form of supports supported with supports having the same height of parallel cables. Cables form a common protection zone l.

Недостатком данного устройства в- л етс невозможность обеспечени свободного пространства над защищаемым объектом, а при защите больших площадей дл обеспечени высокой надежности защиты - увеличенный расход ме- JQ талла, за счет увеличени количества пар опор, соединенных между собой тросом, а также за счет увеличени их высоты, так как с увеличением рассто ни между опорами увеличиваетс стрела провеса троса.The disadvantage of this device is the impossibility of providing free space above the protected object, and when protecting large areas to ensure high reliability of protection, an increased consumption of JQ tal is achieved due to an increase in the number of pairs of supports interconnected by a cable, as well as by increasing their heights, as the sag of the cable increases as the distance between the supports increases.

Наиболее близким по технической сущности, к изобретению вл етс молниезащитное устройства, включающее опоры и штыревые вертикальные молнюесриемники , прикрепленные к верхней части опор, причем опоры расположены по периметру окружности вокруг защищаемого объекта. Дл образовани общей зоны защиты и дл обеспечени надежности защиты объекта количество опор должно быть не менее трех, а при защите объектов, занимающих большую площадь и более Cl3.The closest in technical essence to the invention is a lightning protection device, including supports and pin vertical lightning receivers attached to the upper part of the supports, with the supports located around the perimeter of the circle around the object to be protected. To form a common protection zone and to ensure the reliability of the protection of the object, the number of supports must be at least three, and when protecting objects that occupy a larger area and more than Cl3.

Недостатком данного устройства вл етс увеличенный расход металла, обусловленный необходимостью применени большого количества одиночных стержневых молниеотводов при защите объектов, занимающих большую площадь.The disadvantage of this device is increased metal consumption, due to the need to use a large number of single rod lightning rods for the protection of objects that occupy a large area.

Claims

The purpose of the invention is to reduce material consumption. 3 The goal is achieved by the fact that, in a lightning protection device, including supports and a pin vertical lightning receptacles attached to the upper part of the supports, each of the supports is provided with consoles located at an angle to each other, and the pin lightning receivers are located at the ends of the consoles. 1 shows a schematic of a lightning protection device, a general view of FIG. 2, a section A-A in FIG. 1; on fig.Z section bb in figure 1. The lightning protection device includes supports 1 located at some distance from object 2, made with two cantilevers 3 arranged in a horizontal plane at an angle to each other and attached to the top of the supports 1. At the ends of the consoles 3 vertical pin detectors are located. Axis 5 consoles can be located to each other at angles of 30 - 90 °. General protection zones of lightning arresters of the proposed design is shown in figure 1 and 2 by the dotted line. 5 When using a lightning protection device of this design, for the reliable protection of an object, only two supports can be installed, which leads to a significant reduction in material intensity. Claims of the invention A lightning protection device comprising supports and pin vertical lightning rods attached to the top of the towers, characterized in that, in order to reduce material consumption, each of the supports is provided with consoles angled to each other, and the pin lightning rods are located at the ends of the consoles.
