Embodiment 1

[0014] As shown in accompanying drawing 1, it is the general diagram of the integrated lightning protection device of railway signal microelectronic equipment of the present invention, and lightning-terminating device (SLE) prevents direct strike lightning, and its effect is to induce thunder or intercept lightning, promptly lead lightning current down. The form and spacing of the lightning-terminating device are designed according to the shape of the building and the layout of the equipment. According to the structure of the building in the signal machine room, the lightning-terminating device of the present invention adopts a roof lightning protection net structure, which is composed of a grid not greater than 3m×3m. The grid consists of Hot-dip galvanized flat steel cross-welded construction. Multiple independent lightning rods are installed in areas where outdoor electronic equipment is concentrated.
