Description

{MOVABLE LIGHTNING PROTECTION EQUIPMENT FOR MILITARY FACILITY}

The present invention relates to a mobile lightning prevention device for military facilities installed to prevent lightning damage to military facilities such as radars installed outdoors.

As shown in FIG. 1, the conventional mobile lightning protection device (1) for military facilities has a lightning arrester on a plurality of carts (20) moving along a rail (10) installed around the military facility (2) in which the radar is accommodated. It takes a configuration in which the support 30 is mounted.

Due to the difference in the circumferential length of the inner rail 11 and the outer rail 12, the rail 10 has an inner wheel 21 and an outer wheel 22 as shown in FIG. 2 in the conventional bogie 20. This individually driven method was adopted. In this case, the inner and outer wheels 21 and 22 must rotate according to the correct ratio, but if differences in electrical characteristics such as voltage drop or change in current occur during the individual driving process, serious malfunction or damage may occur. There were concerns.

In addition, the lightning arrester strut 30 mounted on the bogie 20 is a fixed prop as shown in FIG. 3, and not only is there an inconvenience in that installation and disassembly must be accompanied by climate change, but the installed lightning arrester strut 30 Because it is affected by the wind, the wire 31 is connected to the ground and fixed as shown in the drawing. However, in order to move the bogie 20, the wire 31 must be released, so it is possible to quickly respond to emergency situations. There was a problem that there was no

In addition, in FIG. 2, the wheels 21 and 22 of the bogie 20 may freeze with the rails 11 and 12 in the winter, making driving impossible. In this case, the wheels 21 and 22 of the bogie 20 are frozen by pushing the bogie 20 by manpower. There was the inconvenience of having to separate the attached wheels (21, 22) and rails (11, 12) or heat the frozen area with a portable torch.

In addition, the lightning arrester support 30 is grounded by contacting the ground terminal 32 installed on the cart 20 to the fence-shaped ground 40 installed on the outside of the rail 10, as shown in FIG. 4. However, in order to allow abnormally high voltages or currents such as lightning to pass without difficulty, an improvement plan was required to significantly reduce the contact resistance between the ground terminal 32 and the ground 40.

Therefore, the purpose of the present invention is to provide a mobile lightning protection device for military facilities that has an improved configuration compared to the prior art, such that a bogie equipped with a lightning arrestor support can move smoothly along a rail installed around the facility.
